Introduction
Current (past 30-day) vaping among U.S. adolescents has
increased dramatically in recent years.1,2 Rates almost doubled
from 2017 (11.0% of 12th graders) to 2018 (20.9%), the largest
substance use increase ever observed in the 44-year history of
the national Monitoring the Future study.1 Vapes have been
the most commonly used tobacco product among adolescents
since 2014,2 and more than 5 million middle and high school
students were current vape users in 2019.3 These dramatic
increases have offset reductions in cigarette smoking, fueling an
overall increase in adolescent current tobacco use.1,4
This explosion of vaping is concerning because of the risks
associated with adolescent vape use. Adolescents who vape are
more likely than non-users to initiate cigarette smoking and
escalate smoking among those who have already experimented
with cigarettes,5-11 though this association may be due to
shared risk factors for vaping and smoking.12 Researchers are
beginning to understand the chemical constituents and health
implications of vape juice and aerosols, which include carcino-
gens and irritants.8,13-17 Although long-term health effects are
unknown, vaping may be associated with short-term risks
including respiratory symptoms, asthma, and bronchitis among
adolescents.8,18,19 In addition, nicotine exposure affects
adoles-
cent brain development, leading to long-term cognitive issues
including memory and attention impairment.20-22
Despite the alarming increase, teens who vape remain a
minority of the adolescent population.3 Little is known about
which youth are at the greatest risk beyond demographic
descriptions, leaving public health interventionists with a lim-
ited understanding of who should be prioritized in prevention
efforts. Current vaping is more prevalent among male, non-
Hispanic White, higher socioeconomic status, and lesbian, gay,
and bisexual adolescents and young adults.23-27 In addition,
young current vape users often have friends and family mem-
bers who vape or who accept vaping,28 and use other
substances
including cigarettes and marijuana.29-31

ABSTRACT
BACkgRoUnd: Adolescent vaping continues to rise, yet little is
known about teen vape users beyond demographics. Effective
intervention
requires a deeper understanding of the psychographics and
interests of adolescent vape users to facilitate targeted
communication
campaigns.
MeTHodS: We analyzed the 2017-2018 weighted cross-sectional
online survey data from Virginia high school students (N =
1594) to iden-
tify and describe subgroups of adolescents who vaped.
Participants reported 30-day vape use, identification with 5 peer
crowds (Alterna-
tive, Country, Hip Hop, Mainstream, Popular), social
prioritization, agreement with personal values statements, social
media and smartphone
use, and television and event preferences. We compared vaping
rates and frequency by peer crowd using a chi-square analysis
with follow-
up testing to identify higher-risk crowds and confirmed
associations using binary and multinomial logistic regression
models with peer crowd
scores predicting vaping, controlling for demographics. We then
used chi-square and t tests to describe the psychographics,
media use,
and interests of higher-risk peer crowds and current vape users
within those crowds.
ReSUlTS: Any current vaping was the highest among those with
Hip Hop peer crowd identification (25.4%), then Popular
(21.3%). Stronger
peer crowd identification was associated with increased odds of
any current vaping for both crowds, vaping on 1 to 19 days for
both crowds,
and vaping on 20 to 30 days for Hip Hop only. Compared with
other peer crowds and non-users, Hip Hop and Popular youth
and current
vape users reported greater social prioritization and agreement
with values related to being social and fashionable. Hip Hop
and Popular
youth and current vape users reported heavy Instagram and
Snapchat use, as well as unique television show and event
preferences.
ConClUSIonS: Hip Hop and Popular adolescents are most likely
to vape and should be priority audiences for vaping prevention
cam-
paigns. Findings should guide the development of targeted
health communication campaigns delivered via carefully
designed media
strategies.

2 Tobacco Use Insights
Audience psychographics move beyond demographics to
provide health communicators with critical insights about val -
ues, identities, and interests that can inform effective messag-
ing and campaign strategies.32-35 In addition, these insights are
critical for the effective planning and execution of modern
digital media campaigns that rely on interest-based targeting
to deliver digital advertisements to the intended audience.36
Past studies describing ever and current vape users have typi -
cally focused on vaping attitudes and beliefs,37-40 or have used
psychographics and motivations to segment adult, but not ado-
lescent, vape users into discrete subgroups.41,42 Only a few
studies have examined the psychographics of adolescent or
young adult vape users, revealing that novelty-seeking, sensa-
tion-seeking, and lower social conservatism are generally asso-
ciated with ever and current vaping in these
populations.27,43,44
From this basis, we seek to expand health communicators’
understanding of the psychographics, identities, media use, and
interests of adolescent current vape users to inform the devel -
opment of effective vaping prevention campaigns.
Knowing which adolescents vape, what other substances
they use, what they care about, and what influences them is
crucial to addressing adolescent vaping. Commercial market-
ing, including vape marketing, relies on audience segmentation
to identify population subgroups with shared desires and needs
for whom a tailored brand can be built and marketed via tar -
geted media channels.45 In health communications, a similar
approach is necessary to counter industry marketing by identi -
fying adolescent subgroups at the greatest risk for vaping,
developing targeted campaigns that appeal to their shared val -
ues, beliefs, and interests, and delivering campaign content via
specific media channels and strategies to ensure the target
audience is reached.45 Health campaigns designed around the
psychographics of their target audiences are effective,45-47 but
this approach requires a clearly defined audience with unique
characteristics for whom appealing content can be tailored.
Importantly, campaigns must both tailor messaging (by select-
ing messaging that caters to audience preferences, values, and
interests to capture attention and increase persuasion) and tar-
get media delivery (by selecting highly specialized media chan-
nels and using state-of-the-art ad-targeting technologies) to
effectively reach their target audiences in the modern, cluttered
media environment.47 Although much is known about the
demographics of adolescent vape users, health educators lack
crucial information about their values, influences, and interests
that is necessary to define an audience and deliver effective,
targeted communications.
To fill this gap, we used online survey data to describe the
risk profile, psychographic characteristics, and interests of ado-
lescent current vape users in a single U.S. state. We had 2 pri -
mary objectives: to identify potential target audiences for
adolescent vaping prevention campaigns and to describe the
psychographics, media use, and interests of these higher-risk
youth to inform campaign planning. First, we sought to define
potential target audiences by applying a peer crowd audience
segmentation approach. Peer crowds are macro-level subcul-
tures with shared interests, values, and norms47,48 which
are associated with adolescent and young adult health
behaviors49-57 and have served as the basis for targeted health
interventions.58-64 For example, the Commune campaign
target-
ing Hipster peer crowd young adults resulted in reductions in
cigarette smoking associated with stronger anti-tobacco atti-
tudes among those recalling the campaign,58,62 whereas
engage-
ment with the Down and Dirty campaign was associated with
stronger anti-chewing tobacco attitudes and lower odds of cur-
rent use among Country peer crowd teens.61 In this study, we
examined vaping behavior for 5 adolescent peer crowds previ -
ously established in the literature: Alternative (counterculture,
value creativity and uniqueness), Country (patriotic, value hard
work and being outdoors), Hip Hop (confident, value over-
coming struggles and proving themselves), Mainstream
(future-oriented, value organization and stability), and Popular
(extroverted, value socializing and
excitement).47,49,50,52,54,55,61
After identifying the highest risk peer crowds, we sought to
create a profile of these audiences by examining their broader
health risk profiles, psychographics (social prioritization and
personal values), digital behaviors (social media and smart-
phone use), and interests (television shows and events). With
this information, we aimed to identify and describe segments
of adolescents most in need of targeted vaping interventions to
provide clear guidance for health message development and
media targeting.
Methods
Sample and design
We collected cross-sectional online survey data from high
school students ages 13 to 19 living in the U.S. state of Virginia
(N = 1594). Participants were recruited from November 2017
to January 2018 using paid Instagram and Facebook advertise-
ments that directed interested individuals to a screener to
determine eligibility (13-19 years old, current high school stu-
dent, and Virginia resident). Eligible youth were invited to par-
ticipate in the full survey and provided electronic assent (ages
13-17) or consent (ages 18-19). We delivered a parental opt-
out form via email for participants ages 13 to 17. Qualified
participants who completed the full survey received a US$10
electronic gift card incentive. We implemented numerous fraud
prevention and detection measures to maximize data integrity,
including concealing eligibility criteria during screening, col -
lecting email addresses to prevent duplicate completi ons, and
reviewing responses for inconsistencies. Chesapeake IRB
approved the study (No. Pro00023204).
Measures
To address our research objectives, we examined participant
demographics; current vaping, tobacco, and other substance
use; peer crowd identification; 2 psychographic measures,
namely, social prioritization65 and personal values; social
media
Stalgaitis et al 3
and smartphone use; and television show and event
preferences.
Demographics. Participants provided their birthdate, from
which we calculated their age. Participants also indicated their
gender (male, female) and race/ethnicity (Hispanic, non-His-
panic White, non-Hispanic Black, non-Hispanic Asian-Pacific
Islander, and non-Hispanic other including multiracial and
American Indian or Alaska Native).
Past 30-day vape use. Participants reported the number of days
in the past 30 days on which they used e-cigarettes or vapes,
with response options of 0, 1 or 2, 3 to 5, 6 to 9, 10 to 19, 20 to
29, and all 30 days. To mirror commonly reported statistics, we
examined both any current vaping (1-30 days) and frequency of
vaping defined as occasional use (1-19 days) or frequent use
(20-30 days).66
Past 30-day tobacco and substance use. Participants also
reported
the number of days in the past 30 days on which they used
cigarettes; cigars, cigarillos, and little cigars (cigar products);
smokeless tobacco; hookah; alcohol; marijuana; and prescrip-
tion medication without a prescription. Those who reported
any past 30-day use were considered current users of that item.
Peer crowd identif ication. Participants completed Rescue
Agency’s I-Base Survey®, a photo-based tool that measured
identification with 5 peer crowds: Alternative, Country, Hip
Hop, Mainstream, and Popular. The I-Base Survey has identi-
fied consistent patterns of peer crowd prevalence and health
risks in adolescents across the United States.49-52,55,57,61,64
In
brief, participants viewed a grid of 40 photos of unknown
female adolescents and selected 3 who would best and 3 who
would least fit with their main group of friends; they then
repeated the process with male photos. Photos were presented
in random order to each participant to reduce order effects, and
represented a mix of races/ethnicities and peer crowds deter-
mined through prior qualitative research. Participants earned
positive points for the peer crowds of photos selected as the
best fit and negative points for those selected as the least fit,
resulting in a score ranging from –12 to 12 for each of the 5
crowds. For analyses, we assigned participants to each crowd
with which they had at least some identification, defined as a
score of 1 or more on the I-Base Survey for that crowd. Partici-
pants could be assigned to more than 1 peer crowd as they
could score positively for multiple crowds.
Social prioritization index. Participants completed the social
prioritization index (SPI), a validated measure of the degree to
which an individual places importance on their social life that is
associated with young adult cigarette use.58,59,65 The SPI
included 13 questions: 8 items wherein participants selected 1
response that best described them from a pair (up for anything/
pick and choose what to do, outgoing/low-key, center of
attention/lay low, street smart/book smart, partier/studier, wing
it/plan it out, the carefree one/the responsible one, in a picture I
. . . strike a pose/smile big); 3 true or false items (In groups of
people, I am rarely the center of attention; I have considered
being an entertainer or actor; I can look anyone in the eye and
tell a lie with a straight face); 1 item asking how many nights
they went out for fun in the past week (0-1, 2-3, 4-5, 6-7
nights);
and 1 item asking how late they typically stayed out when they
went out for fun (9:59-10:59 pm, 11:00 pm-12:59 am, 1:00-
2:59 am, 3:00 am or later). To calculate the SPI score (range:
0-17), participants received 1 point for each socially oriented
selection for the 8 descriptive pairs and 3 true/false questions,
and received 0 points for selecting 0-1 nights per week or 9:59-
10:59 pm, 1 point for 2-3 nights per week or 11:00 pm-12:59
am,
2 points for 4-5 nights per week or 1:00-2:59 am, and 3 points
for 6-7 nights per week or 3:00 am or later.
Personal values. Participants viewed 26 personal values state-
ments (e.g., I think it is more important to live in the moment
than focus on the future) and rated each on a 5-point Likert-
type scale from 1 (strongly disagree) to 5 (strongly agree).
Past 7-day social media use. Participants reported if they had
consumed or created content on 6 social media platforms in the
past 7 days: Facebook, Instagram, Twitter, Tumblr, Snapchat,
and Pinterest.
Lifetime smartphone use. Participants were asked if they had a
smartphone, and if so, if they had ever used their smartphone
to engage in 9 different activities (e.g., listen to an online radio
or a music service such as Pandora or Spotify; watch movies or
TV shows through a paid subscription service like Netflix).
Television show preferences. Participants selected all television
shows they regularly watched from a list of 24 broadcast and
streaming shows popular with youth (e.g., 13 Reasons Why,
Ridiculousness).
Event preferences. Participants selected all events they
regularly
attended from a list of 25 leisure time events youth might
attend (e.g., sports games, high school dances).
Statistical analysis
Respondents were required to complete the survey, so no data
were missing. Data were weighted to the gender, race/ethnicity,
and urban/rural demographics of Virginia teens for all analy-
ses. As a first step, we ran weighted and unweighted frequen-
cies and means for demographic measures.
To address our first objective of identifying which adoles -
cents were at the greatest risk, we used chi-square tests to com-
pare the rates of current vaping and vaping frequency among
those who did and did not identify with each crowd, using
follow-up z tests with Bonferroni correction to identify specific
4 Tobacco Use Insights
significant differences. To confirm that associations persisted
while controlling for demographics, we ran separate binary and
multinomial logistic regression models for each peer crowd,
with a single peer crowd’s score (range: –12 to 12) predicting
odds of current vaping, or of occasional or frequent vaping,
while controlling for age, gender, and race/ethnicity. We also
ran binary logistic regression models for each crowd to predict
odds of any current cigarette, cigar product, smokeless tobacco,
hookah, alcohol, and marijuana use, and any current prescrip-
tion medication misuse, to understand the broader risk profile
of the peer crowds. We ran separate models for each peer crowd
to avoid multicollinearity associated with including all 5 scores
in a single model.
After identifying 2 peer crowds at elevated risk for vaping,
we addressed our second objective of developing interest-based
profiles of these potential target audiences by describing their
psychographics (SPI and personal values), social media and
smartphone use, and television and event preferences. We first
compared frequencies and means for those who did and did
not identify with the 2 crowds of interest, using chi-square tests
and t tests to identify significant differences. Then, within the
2 peer crowds, we compared frequencies and means between
current vape users and non-users, using chi-square tests and t
tests to identify significant differences. This approach allowed
us to identify the characteristics of the 2 peer crowds of interest
to inform campaign content and media targeting, as well as to
hone in on psychographics and interests that specifically char -
acterized current vape users within the higher-risk crowds.
Due to the relatively small subset of participants who were fre-
quent vape users, we focused on any current use to improve the
reliability of results. Tables present items that differed signifi -
cantly between groups in at least 1 analysis and had endorse-
ment rates above 5.0%.
Results
The weighted mean age of the sample was 16.47 years, and
about half identified as female (50.8%) and as non-Hispanic
White (55.3%) (Table 1). The most common peer crowd iden-
tifications were Popular (63.1%) and Mainstream (62.6%).
Race/ethnicity and gender breakdowns differed by crowd
(Supplemental Appendix Table 1).
Consistent with 2018 National Youth Tobacco Survey
results,2 20.6% of Virginia high school students in our sample
currently vaped (Table 2). A significantly greater proportion of
those with any Hip Hop peer crowd identification currently
vaped (25.4%) than those with no Hip Hop identification
(18.0%, P < .001). In binary logistic regression models using
each peer crowd score (–12 to 12) to predict odds of current
vaping while controlling for demographics, a 1-point increase
in the Popular score was associated with a 4% increase in odds
of current vaping, whereas a 1-point increase in the Hip Hop
score was associated with a 10% increase.
Further differentiating current vape users in the sample,
17.0% were occasional vape users (1-19 days in the past 30
days)
and 3.7% were frequent users (20-30 days). Those with any
Hip Hop identification reported higher rates of occasional
vaping (21.2%) than others (14.6%, P < .05). Although rates of
frequent vaping did not differ significantly for any peer crowd,
stronger Hip Hop identification was associated with greater
odds of both occasional and frequent vaping. Stronger Popular
identification was associated with greater odds of occasional
vaping only. In addition, stronger Hip Hop identification was
associated with greater odds of current cigarette, cigar product,
hookah, alcohol, and marijuana use, whereas stronger Popular
identification was associated with lower odds of use for many
products.
Based on the chi-square tests and logistic regression results,
we identified the Hip Hop and Popular peer crowds as being at
elevated risk for vaping. We then characterized the psycho-
graphics (Table 3), social media and smartphone use (Table 4),
and interests (Table 5) of Hip Hop and Popular youth in gen-
eral, as well as Hip Hop and Popular current vape users in
particular.
Overall, Hip Hop participants were social, trendy individu-
als interested in hip hop/rap music and sports. Compared with
those with no Hip Hop identification, Hip Hop youth had
higher SPI scores, in particular describing themselves as par -
tiers, street smart, and carefree (Table 3). Hip Hop youth more
often agreed that they make decisions quickly, are fashionable,
are social people with lots of friends, and are tougher than most
people. In contrast, they less often agreed that they are patri -
otic, good students, care what others think about them, care
about keeping their bodies free from toxins, and follow the
rules. A greater proportion of Hip Hop youth used Snapchat in
the past week and used their smartphones to look up sports
scores or analyses than those with no Hip Hop identification
(Table 4). Many TV shows more often endorsed by Hip Hop
youth revolved around hip hop/rap musical interests, such as
Love & Hip Hop, The Rap Game, and Wild ’N Out (Table 5).
Similarly, Hip Hop youth more often indicated that they regu-
larly attend hip hop concerts and dance clubs than others, as
well as basketball and football games.
Characteristics of vape users within the Hip Hop peer
crowd largely reflected an amplification of the broader crowd’s
profile. Hip Hop vape users had higher SPI scores than non-
users within the crowd, and they described themselves as par-
tiers, street smart, carefree, and up for anything (Table 3). They
more often agreed that they are fashionable, use their clothes to
express their identity, and are tough, and less often agreed that
they follow the rules, follow tradition, and care about keeping
their bodies free from toxins than non-users. A greater propor-
tion of Hip Hop vape users reported using Snapchat, Instagram,
and Twitter in the past week than non-users (Table 4). Hip
Hop vape users also more often reported using their smart-
phones to look up sports scores and analyses, stream music, and
make video calls than non-users. Hip Hop vape users more
often reported watching 2 cartoon shows, The Boondocks and
Bob’s Burgers, than non-users (Table 5). Similar to the overall
Stalgaitis et al 5
crowd, a greater proportion of Hip Hop vape users indicated
that they attend dance clubs, hip hop concerts, basketball
games, and football games than non-users.
Popular youth shared some characteristics with Hip Hop
youth, but also differed in key ways. Although Popular and Hip
Hop youth both reported higher SPI scores than others, the
specific SPI items they endorsed often differed (Table 3).
Though both Hip Hop and Popular youth described them-
selves as partiers, Popular youth also described themselves as
the center of attention, outgoing, and up for anything, which
were not significant in Hip Hop analyses. Similar to Hip Hop
youth, Popular youth more often agreed that they are fashion-
able and are social people with lots of friends. However,
Popular
youth also more often agreed that they care about being good
students, keeping their bodies free from toxins, and being
patriotic, items with which Hip Hop youth less often agreed.
Popular youth also more often agreed that family is important,
that they try to follow tradition, and that they are religious than
other youth. Popular youth more often reported using
Instagram, Snapchat, and Twitter than other youth and more
often used their smartphones to look up sports scores or analy-
ses and to stream music or video content (Table 4). Compared
with others, Popular youth more often reported watching teen
dramas, including 13 Reasons Why, Jane the Virgin, Pretty
Little
Liars, and Riverdale (Table 5). Sports were favored by Popular
youth, as they more often reported attending basketball, foot-
ball, baseball, and soccer games than others. They also more
often reported attending church events, community service
events, high school dances, and pop and country music
concerts.
Popular vape users shared many traits with the broader
Popular crowd as well as with Hip Hop vape users. Similar to
Hip Hop vape users, Popular vape users reported higher SPI
scores than non-users, describing themselves as outgoing,

12 Tobacco Use Insights
partiers, street smart, carefree, and up for anything (Table 3).
Popular vape users also more often agreed that they care about
being fashionable, social, and tough than non-users and less
often agreed that they care about keeping their bodies free
from toxins and following the rules, similar to Hip Hop vape
users. Although, overall, Popular youth more often agreed that
they value family, tradition, and religion than other youth,
Popular vape users less often agreed with these items than non-
users. Similar to the broader Popular peer crowd and to Hip
Hop vape users, Popular vape users more often reported using
Instagram and Snapchat, and using their smartphones to look
up sports scores and place video calls (Table 4). Popular vape
users, like Hip Hop vape users, more often reported watching
The Boondocks and Bob’s Burgers than non-users (Table 5).
Similar to the broader Popular crowd, Popular vape users more
often reported attending sports games, high school dances, and
concerts than non-users, though they less often reported
attending church events.
Discussion
This study identified a subset of adolescents at the greatest risk
for vaping, and the psychographic characteristics and interests
that should inform the creation of targeted health communica-
tions messages and media delivery strategies for these youth.
The Hip Hop and Popular peer crowds were at the greatest risk
for current vaping, aligning with earlier representative data
from Virginia and similar studies of young adults.52,53,56
Interestingly, although both crowds were at increased risk for
current vaping, their broader risk profiles diverged, indicating a
need for differentiated health messaging for the 2 crowds. Hip
Hop youth had greater odds of vaping frequently, which may
indicate an escalation to nicotine addiction, and were more
likely to use other tobacco products and substances. Popular
youth, however, were at increased risk for occasional vaping
only, with reduced risk for several other substances including
cigarettes.
Understanding the psychographics and interests of Hip
Hop and Popular youth, and Hip Hop and Popular current
vape users in particular, provides insights for health communi -
cations campaign development and hints at possible explana-
tions for differential risk by crowd. Hip Hop and Popular youth
and current vape users reported higher mean SPI scores than
other youth, and endorsed personal values related to being
fashionable and sociable. These findings paint a psychographic
portrait of Hip Hop and Popular youth and current vape users
as individuals who care about their social lives, are trend sensi -
tive, and are strongly influenced by their social environments.
This portrait aligns with vape marketing campaigns, which
often feature celebrities, associate vaping with socializing and
partying, and use sleek, modern designs reminiscent of trendy
technology such as iPhones,37,67-69 all of which likely appeal
to
the youth described here. To effectively counter industry mar-
keting and media depictions that may appeal to Hip Hop and
Popular adolescents, health educators must create relevant
messaging that breaks the connection between vaping and
social status or trendiness, and motivates youth to reconsi der
vaping as a key feature of their social lives. Furthermore, as
cur-
rent vape users in this study cared less about following rules
and protecting their bodies from toxins than non-users, cam-
paign messaging must look beyond authoritative tones and
typical scare tactic messaging to cultivate a socially influential
brand that can persuade higher-risk youth to avoid vaping by
speaking directly to their priorities and values.
Hip Hop and Popular adolescents and current vape users
also reported extensive smartphone and social media use, in
particular the use of Instagram, Snapchat, sports analysis sites,
and video/music streaming services. Heavy social media use
may contribute to adolescent vaping as user- and industry-
generated vaping content abounds across platforms,70-74 and
early research suggests that heavier social media use and expo-
sure to vape advertisements on social media are associated with
willingness and intentions to vape.75 Given the known associa-
tion between exposure to online tobacco marketing and adoles-
cent tobacco initiation and progression,76,77 heavy social
media
use among Hip Hop and Popular adolescents may further
explain why these youth vape. At the same time, these findings
can guide health communicators in selecting relevant cam-
paign channels and delivering content via targeted advertise-
ments. Vaping prevention campaigns must meet higher-risk
adolescents where they are to deliver messaging to the target
audience using the cutting-edge ad-targeting technology
employed by commercial advertisers. Although not yet ubiqui -
tous in public health, the targeted placement of paid campaign
advertising has been successfully applied to deliver health com-
munications to intended audiences for initiatives including the
U.S. Food and Drug Administration’s The Real Cost general
market and Fresh Empire Hip Hop adolescent tobacco educa-
tion campaigns.35,61,78,79 In addition, to counter the
abundance
of pro-vaping content youth encounter online, health commu-
nication campaigns must cultivate active, appealing social
media presences to establish themselves as relatable and trust-
worthy social influencers and interject tailored prevention mes -
saging into the pro-vaping social media environments of
higher-risk youth.80,81
Finally, Hip Hop and Popular youth and current vape users
reported specific television and event preferences. Although
vaping is currently rare in television programming,82,83
exposure
to vape advertisements on television and to vaping in other
forms of media including music videos is common and may
promote positive attitudes toward vaping among youth.84-89
Although it is unclear if Hip Hop and Popular adolescents are
disproportionately exposed to vape advertisements or onscreen
vaping, continued monitoring is warranted to track how vaping
is depicted over time and if exposure to vaping in media is asso-
ciated with risks similar to that of exposure to cigarette
smoking
in movies.90 In addition, little is known about vape industry
sponsorship or promotion at events, an important topic for
future work given the tobacco industry’s historical use of events
Stalgaitis et al 13
for product promotion.91,92 Although less is known about how
television and event preferences may influence vaping ri sk, this
information is incredibly useful to health educators for cam-
paign tailoring and media targeting. Interests can be used to
build media targeting profiles that concentrate message delivery
and dosage on those most at risk, increasing chances for suc-
cessful attention and persuasion. Television preference data can
inform media buys,93 identify potential influencer partnerships,
and reveal opportunities to engage with the target audience
about relevant televised events.81 Event preference data can
inform the selection of relevant settings for advertisements and
identify opportunities for in-person engagement with the target
audience. With this wealth of information, health educators can
develop targeted health communication interventions that
effectively reach and persuade higher-risk adolescents.
Although the Hip Hop and Popular peer crowds shared
some psychographics and preferences, differences between the
crowds indicate that separate campaigns are necessary. In par -
ticular, different messaging approaches are needed to appro-
priately address the more frequent, established nature of
vaping among Hip Hop youth, who may require cessation
resources, and the less frequent, possibly social nature of vap-
ing among Popular youth. Experimental studies have demon-
strated the promise of peer crowd-targeted smoking prevention
messaging,94-96 and evaluation studies of peer-crowd-targeted
campaigns reveal success in addressing cigarette and smoke-
less tobacco use.58-62,64 Peer crowd targeting may also be a
means of more effectively addressing tobacco use disparities.
Previous literature suggests that non-Hispanic White youth
are at the greatest risk for vaping,23-25,27 but this study indi-
cates that the Hip Hop peer crowd, which overrepresents
racial/ethnic minorities (Supplemental Appendix Table 1),50-
52,54 is at the greatest risk for frequent vaping, identifying a
higher-risk group that might otherwise be missed by cam-
paigns using demographic segmentation. This study provides
a preliminary insight into who these youth are, what they care
about, and the media they consume; future research must test
potential campaign messages with youth from the targeted
peer crowd to ensure that tailored content resonates and moti -
vates positive behavior change.
Limitations
It is important to note several limitations of this study.
Generalizability is unclear as we surveyed a convenience sam-
ple recruited via social media from a single state, although peer
crowd risk findings did align with previous observations from
varied samples and locations.52,53,55,56 We did not collect
vape
brand preferences, and did not distinguish between vaping
nicotine, tetrahydrocannabinol (THC) or marijuana products,
and flavors only, which should be explored to determine if users
of different products have unique characteristics and interests.
We also cannot discern causality, such as whether any of these
psychographic characteristics or interests predisposed teens to
increased interest in vaping, or if targeted industry marketing
or other factors may have contributed to disparities.
Conclusions
Tackling adolescent vaping requires understanding who is at the
greatest risk and how to reach them with relevant, persuasive
messaging. Although current vaping is increasingly common
among U.S. adolescents, risk is not evenly distributed, and pre-
vention efforts should rely on psychographic segmentation,
audience tailoring, and media targeting to effectively and effi -
ciently reach higher-risk adolescents.45 Although establishing a
deeper understanding of the psychographics and interests of
higher-risk adolescents may appear burdensome, in fact it is
nec-
essary to ensure that limited public health funds are spent on
the
populations facing the greatest challenges,46 particularly in
today’s online media environment where platform targeting
tools cater toward advertisers who know the interests of their
audiences. Our findings provide a detailed portrait of adoles -
cents who are at increased risk for current vaping, information
which should directly inform health communication campaign
planning. Future campaigns should incorporate our findings to
create messages relevant to the psychographics and risk profiles
of these youth, which are delivered using carefully selected
media
strategies reflecting the greatest opportunities to reach the
target
audience efficiently. Addressing the urgent adolescent vaping
crisis requires looking deeper than demographics to understand
and leverage knowledge about who adolescent vape users are
and
what they care about, to create health communications cam-
paigns that appeal to and persuade those at the greatest risk.

EMPIRICAL RESEARCH
Schools Influence Adolescent E-Cigarette use, but when?
Examining

Abstract
Schools are important contexts for adolescent health and health-
risk behaviors, but how stable is this relationship? We
develop a conceptual model based on Ecological Systems
Theory describing the changing role of schools for adolescent
health outcomes—in this case, teen e-cigarette use. To examine
this change, we fit Bayesian multilevel regression models to
two-year intervals of pooled cross-sectional data from the
2011–2017 U.S. National Youth Tobacco Survey, a school-
based
study of the nicotine use behaviors of roughly 65,000 middle
and high school students (49.5% female; 41.1% nonwhite; x
̄
age of 14.6 ranging from 9 to 18) from over 700 schools. We
hypothesized that school-level associations with student e-
cigarette use diminished over time as the broader popularity of
e-cigarettes increased. Year-specific variance partitioning
coefficients (VPC) derived from the multilevel models indicated
a general decrease in the extent to which e-cigarette use
clusters within specific schools, suggesting that students across
schools became more uniform in their propensity to vape
over the study period. This is above and beyond adjustments for
personal characteristics and vicarious exposure to smoking
via friends and family. Across all years, model coefficients
indicate a positive association between attending schools where
vaping is more versus less common and student-level odds of
using e-cigarettes, suggesting that school contexts are still
consequential to student vaping, but less so than when e-
cigarettes were first introduced to the US market. These
findings
highlight how the health implications of multiply-embedded
ecological systems like schools shift over time with
concomitant changes in other ecological features including
those related to policy, culture, and broader health practices
within society. Though not uniformly reported in multilevel
studies, variance partitioning coefficients could be used more
thoughtfully to empirically illustrate how the influence of
multiple developmentally-relevant contexts shift in their
influence
on teen health over time.

Introduction
Use of electronic cigarettes (“e-cigarettes”) among adoles-
cents has rapidly proliferated. Between 2011 and 2015, the
prevalence of current e-cigarette use climbed from 0.6% to
5.3% among US middle schoolers, and from 1.5% to 16%
among high schoolers (Singh et al. 2016a). More recent
estimates suggest continued increases from 2015-2018 with
the widening popularity of novel “vaping” modalities
including Juul devices (Gentzke et al. 2019). These patterns
have emerged alongside historic lows in conventional
tobacco use among teens who now favor vaping over
smoking (Johnston et al. 2016). Conventional smoking
remains among the most powerful correlates of adolescent
e-cigarette use (Lippert 2018), though evidence suggests a

bi-directional relationship with e-cigarette use being linked
to a higher probability of future smoking, even among
tobacco-abstinent teens (Bunnell et al. 2015; Coleman et al.
2014; Leventhal et al. 2015; Wills et al. 2015). In addition
to the health risks associated with vaping (Chun et al. 2017;
El-Hellani et al. 2018; Larcombe et al. 2017; Moheimani
et al. 2017), the link between vaping and conversion to
smoking has driven interest in how the traits of adolescents
and the contexts they engage with most are associated with
vaping.
Schools have long been recognized as critical contexts
that shape youth health-risk behaviors (Alexander et al.
2001; Bonell et al. 2013a; Bonell et al. 2013b; Ellickson
et al. 2003), including vaping (Corsi and Lippert 2016;
Lippert 2018). However, recent population-wide trends call
to question whether adolescent e-cigarette use has remained
concentrated in particular schools or if the likelihood of
vaping has become more uniform among students across
schools. Responding to this question, the current study
draws on Ecological Systems Theory (Bronfenbrenner
1977; Bronfenbrenner and Morris 1998) to investigate two
research questions: (1) How has the school clustering of
vaping—a measure of the extent to which schools differ
based on their prevalence of student e-cigarette use—
changed between 2011 and 2017 as the population-wide
prevalence of youth vaping increased? (2) How is the pre-
valence of school-level e-cigarette use associated with a
student’s odds of vaping net of key influences from one’s
family and peer group? To answer these questions, pooled
cross-sectional data from the 2011 to 2017 National Youth
Tobacco Surveys (NYTS) are used to decompose variance
partitioning coefficients from multiyear multilevel regres-
sion models of students nested within schools across the
US. Variance partitioning components (VPC) provide an
empirical estimate of school influence and a measure of the
similarity of e-cigarette use or abstinence between students
within schools. Thus, year-specific VPCs allow an assess-
ment of change in the school clustering of teen vaping over
a period when adolescent e-cigarette use emerged as a
population health concern.
The Ecology of Youth Vaping
According to Ecological Systems Theory, youth develop-
ment is guided by influences across multiply-embedded
systems. These include features within the exosystem and
macrosystem – broad societal influences such as public
policy, culture, and population-wide trends—and the
microsystem, or those institutions and relationships nearest
to youth such as schools, families, and peers. Connections
between and within the two systems are made via the
mesosystem, a “system of systems” comprised of the reci-
procal relationships among ecological features, such as
federal policies in the exosystem that alter family- or
school-based processes in the microsystem. A fifth dimen-
sion of the ecological model is the chronosystem, which
reflects the developmental implications of both an indivi -
dual’s stage in the life course and the sociohistorical context
within which ecological systems are embedded and
experienced. This aspect of ecological theory is critical for
the purposes of this study, though the chronosystem has
received less attention than features within the microsystem
(Tudge et al. 2016).
Schools and Youth Health Behaviors
The association between school contexts and youth vaping
is made clearer by the conceptual model developed by
Frohlich and colleagues (Abel and Frohlich 2012; Frohlich
et al. 2002; Frohlich, Corin and Potvin 2001), a complement
to ecological theory. The model describes the interplay
between contextual and agentic factors that produce—and
are produced by—community features. According to this
model, health behaviors are viewed as “generated prac-
tices,” or products of both structural conditions and self-
determination. This perspective is rooted in Weber’s dis-
tinction between “life chances”—features of social structure
that free or constrain human agency, and “life choices”—
the health behaviors enacted by individuals responding to
structural demands and opportunities (Hays 1994). Abel and
Frohlich (2012) elaborate on self-determination by
describing it in terms of its contextual embeddedness, or the
“socially-structured development, acquisition, and applica-
tion of structural and personal resources by individuals in a
given context,” (p. 239). Under this view, the consequences
of human agency can be understood as both the healthy and
unhealthy practices among individuals responding to con-
textual demands and opportunities, which reinforces the
“collective health lifestyles” practiced among community
members (Frohlich, Corin and Potvin 2001).
Like ecological theory, this model acknowledges the
developmental importance of school environments and the
reciprocal nature of relationships among features within and
between ecological systems. Evidence from countless stu-
dies lends empirical support to these claims. Given the
recency of vaping as a population health concern much of
this research is focused on other related outcomes, such as
conventional tobacco use. These studies show that students
—even low-risk students—attending schools with high
rates of smoking are themselves more likely to smoke
(Alexander et al. 2001; Leatherdale and Manske 2005). The
association between school-level factors and adolescent
smoking has proven robust to a range of confounders at the
individual, family, and neighborhood levels (Dunn et al.
2015). Evidence from a limited number of studies on
schools and e-cigarette use also show that youth attending
1900 Journal of Youth and Adolescence (2019) 48:1899–1911
schools where vaping is common are more likely to vape
(Corsi and Lippert 2016).
The mechanisms linking schools to youth health-risk
behaviors are not entirely clear, but may include norms and
the provision of both social and material resources. Norms
include the health beliefs, attitudes, and policies that inhere
within school communities. While school-based policies
have shown inconsistent and often null associations with
adolescent health behaviors, especially smoking (Coppo
et al. 2014; Galanti et al. 2014), the beliefs and attitudes
held among one’s schoolmates have been shown to corre-
late with one’s own beliefs, attitudes, and behaviors. For
instance, there is a persistent and inverse association
between average school-level student attainment and
attendance and student-level substance use (Bonell et al.
2013b), suggesting that school environments supporting
norms that emphasize student achievement discourage
behaviors incompatible with academic success. Conversely,
youth attending schools with lenient norms risk developing
beliefs and attitudes compatible with substance use. For
example, youth attending schools with high versus low rates
of vaping are more likely to believe that e-cigarettes are
harm-free and less addictive than combustible cigarettes,
irrespective of their actual e-cigarette use (Lippert 2018).
In schools with lenient norms that fail to correct students’
misconceptions of the risks associated with e-cigarettes,
pupils are more likely to have access to social and material
resources needed to vape. This includes peer modeling of
vaping behaviors and use of peers’ vaping devices. As a
learned behavior, initiating e-cigarette use is facilitated by
peer modeling and demonstrations. Indeed, a recent mixed-
methods study of adolescents and young adults found that
one-third of the sample first began experimenting with e-
cigarettes because an e-cigarette using friend introduced
them to the practice (Kong et al. 2015). Analysis of quali -
tative data from the same study suggests that when one
member of a peer group acquires an e-cigarette, offers to
use the device are soon made to other group members.
Other learned behaviors associated with e-cigarettes include
performative aspects of use, such as “vaping tricks”
demonstrated by friends or a desire to “look cool,” espe-
cially for younger adolescents (Roditis et al. 2016). Given
the social functions of e-cigarette use it is not surprising that
a recent study showed leisure time activities among e-
cigarette using teens is often centered on a mutual interest in
vaping activities (Evans-Polce et al. 2018).
A Model for Changing School-Level Influence
The temporal stability of the link between school features
and youth health behaviors has not been widely investi-
gated. Ecological Systems Theory acknowledges that the
influence of such systems on youth development is
conditioned by the sociohistorical context in which they are
experienced (Bronfenbrenner and Morris 2006). In the case
of adolescent e-cigarette use, recent changes in the exo and
macrosystems warrant closer inspection of how the role of
schools has changed for teen vaping. These cross-system
relationships are described in Fig. 1.
Following the ecological model, adolescent e-cigarette
use is considered a product of factors found across multiply-
embedded systems, namely the microsystem (school,
family, peer, and individual factors) and exo or macro-
systems (policy, media, culture, and population-wide trends
in e-cigarette use). The conceptual model in Fig. 1 under-
scores the influence that features within the exo and mac-
rosystems have on both schools as well as individual
behaviors. At the level of the exosystem, state and federal
policies on e-cigarettes have a bearing on both individual
consumption (e.g., new minimum age restrictions for pur-
chase) and school functionings (e.g., regulations on e-
cigarette sales near schools). At the level of the macro-
system, cultural shifts—the population-wide rise in e-
cigarette use; youth-targeted marketing campaigns—not
only have direct influences on youth behaviors, but they
also modify the association between school features and
youth behaviors. For instance, the role that peers play in
disseminating beliefs and attitudes about the safety and
benefits of vaping (e.g., looking cool or demonstrating
adult-like behavior) could be augmented, or even sup-
planted by, messages circulating throughout social media
within the macrosystem. Indeed, recent evidence shows that
advertising of e-cigarettes to adolescents has climbed dra-
matically over recent years (Duke et al. 2014; McCarthy
2016), and exposure to such advertising, including celebrity
endorsements via social media, is linked to higher odds of
Fig. 1 Conceptual model of the interdependent association
between
schools and e-cigarette use
Journal of Youth and Adolescence (2019) 48:1899–1911 1901
teen use (Camenga et al. 2018; Hammig, Daniel-Dobbs and
Blunt-Vinti 2017; Pasch et al. 2018; Phua, Jin and Hahm
2018; Singh et al. 2016b). Under this scenario, the impor-
tance of schools to teen vaping could have diminished over
time as analogous influences from other ecological systems
became more pronounced—a phenomenon we refer to as
system drift.
Conversely, other changes in the exo and macrosystems
could have enhanced the relevance of schools to teen vaping
via the mechanisms described earlier. Recently expanded
regulations on e-cigarettes by the FDA (U.S. Food and Drug
Administration 2016) imposed mandatory minimum age
requirements on e-cigarette sales, even though research
shows that sales of e-cigarettes to minors is still common
(Levinson 2018). Should e-cigarettes become more difficult
for youth to purchase, adolescents will rely more on peer-
mediated access organized within schools, raising the
importance of schools to adolescent vaping. Additionally,
important shifts in how teens vape could have strengthened
the role that schools played in facilitating the initial emer -
gence of adolescent e-cigarette use. Manufacturers of
technologically-novel “next-gen” e-cigarette devices have
targeted teenagers in their marketing (Chu et al. 2018) and
to great effect, as devices like Juul have become popular
among youth (Krishnan-Sarin et al. 2019). The evolution of
vaping devices over time could have required localized
peer-to-peer demonstrations of use, peer-mediated access to
vaping materials, and flexible school-based cultural norms
that permit vaping, bringing schools back into focus as the
broader prevalence of teen vaping climbed.
Current Study
While either scenario—diminishing or increasing school-
level influences—is possible, no empirical attention has
been given to how the clustering of adolescent e-cigarette
use within schools has shifted over recent years. Respond-
ing to the lack of attention to shifting school influences on
teen health, Ecological Systems Theory and conceptual
models of school environments and adolescent health (Abel
and Frohlich 2012; Frohlich et al. 2002; Frohlich, Corin and
Potvin 2001) are used to address the following research
questions: (1) How has the school clustering of vaping
changed between 2011 and 2017 as the population-wide

Tobacco Use Insights Volume 13: 1–15 © The Author(s) 2020 Article reuse guidelines: sagepub.com/journals-permissions DOI: 10.1177/1179173X20945695 Introduction Current (past 30-day) vaping among U.S. adolescents has increased dramatically in recent years.1,2 Rates almost doubled from 2017 (11.0% of 12th graders) to 2018 (20.9%), the largest substance use increase ever observed in the 44-year history of the national Monitoring the Future study.1 Vapes have been the most commonly used tobacco product among adolescents since 2014,2 and more than 5 million middle and high school students were current vape users in 2019.3 These dramatic increases have offset reductions in cigarette smoking, fueling an overall increase in adolescent current tobacco use.1,4
  • 2. This explosion of vaping is concerning because of the risks associated with adolescent vape use. Adolescents who vape are more likely than non-users to initiate cigarette smoking and escalate smoking among those who have already experimented with cigarettes,5-11 though this association may be due to shared risk factors for vaping and smoking.12 Researchers are beginning to understand the chemical constituents and health implications of vape juice and aerosols, which include carcino- gens and irritants.8,13-17 Although long-term health effects are unknown, vaping may be associated with short-term risks including respiratory symptoms, asthma, and bronchitis among adolescents.8,18,19 In addition, nicotine exposure affects adoles- cent brain development, leading to long-term cognitive issues including memory and attention impairment.20-22 Despite the alarming increase, teens who vape remain a minority of the adolescent population.3 Little is known about which youth are at the greatest risk beyond demographic descriptions, leaving public health interventionists with a lim- ited understanding of who should be prioritized in prevention efforts. Current vaping is more prevalent among male, non- Hispanic White, higher socioeconomic status, and lesbian, gay, and bisexual adolescents and young adults.23-27 In addition, young current vape users often have friends and family mem- bers who vape or who accept vaping,28 and use other substances including cigarettes and marijuana.29-31 The Vaping Teenager: Understanding the Psychographics and Interests of Adolescent Vape Users to Inform Health Communication Campaigns Carolyn Ann Stalgaitis , Mayo Djakaria and Jeffrey Washington Jordan
  • 3. Research Department, Rescue Agency, San Diego, CA, USA. ABSTRACT BACkgRoUnd: Adolescent vaping continues to rise, yet little is known about teen vape users beyond demographics. Effective intervention requires a deeper understanding of the psychographics and interests of adolescent vape users to facilitate targeted communication campaigns. MeTHodS: We analyzed the 2017-2018 weighted cross-sectional online survey data from Virginia high school students (N = 1594) to iden- tify and describe subgroups of adolescents who vaped. Participants reported 30-day vape use, identification with 5 peer crowds (Alterna- tive, Country, Hip Hop, Mainstream, Popular), social prioritization, agreement with personal values statements, social media and smartphone use, and television and event preferences. We compared vaping rates and frequency by peer crowd using a chi-square analysis with follow- up testing to identify higher-risk crowds and confirmed associations using binary and multinomial logistic regression models with peer crowd scores predicting vaping, controlling for demographics. We then used chi-square and t tests to describe the psychographics, media use, and interests of higher-risk peer crowds and current vape users within those crowds. ReSUlTS: Any current vaping was the highest among those with Hip Hop peer crowd identification (25.4%), then Popular (21.3%). Stronger
  • 4. peer crowd identification was associated with increased odds of any current vaping for both crowds, vaping on 1 to 19 days for both crowds, and vaping on 20 to 30 days for Hip Hop only. Compared with other peer crowds and non-users, Hip Hop and Popular youth and current vape users reported greater social prioritization and agreement with values related to being social and fashionable. Hip Hop and Popular youth and current vape users reported heavy Instagram and Snapchat use, as well as unique television show and event preferences. ConClUSIonS: Hip Hop and Popular adolescents are most likely to vape and should be priority audiences for vaping prevention cam- paigns. Findings should guide the development of targeted health communication campaigns delivered via carefully designed media strategies. keywoRdS: E-cigarette, vaping, adolescent, psychographics, peer crowd, personal value, social media, health communication ReCeIVed: November 26, 2019.

  • 6. Knowing which adolescents vape, what other substances they use, what they care about, and what influences them is crucial to addressing adolescent vaping. Commercial market- ing, including vape marketing, relies on audience segmentation to identify population subgroups with shared desires and needs for whom a tailored brand can be built and marketed via tar - geted media channels.45 In health communications, a similar approach is necessary to counter industry marketing by identi - fying adolescent subgroups at the greatest risk for vaping, developing targeted campaigns that appeal to their shared val - ues, beliefs, and interests, and delivering campaign content via specific media channels and strategies to ensure the target audience is reached.45 Health campaigns designed around the psychographics of their target audiences are effective,45-47 but this approach requires a clearly defined audience with unique characteristics for whom appealing content can be tailored. Importantly, campaigns must both tailor messaging (by select- ing messaging that caters to audience preferences, values, and interests to capture attention and increase persuasion) and tar- get media delivery (by selecting highly specialized media chan- nels and using state-of-the-art ad-targeting technologies) to effectively reach their target audiences in the modern, cluttered media environment.47 Although much is known about the demographics of adolescent vape users, health educators lack crucial information about their values, influences, and interests that is necessary to define an audience and deliver effective, targeted communications. To fill this gap, we used online survey data to describe the risk profile, psychographic characteristics, and interests of ado- lescent current vape users in a single U.S. state. We had 2 pri - mary objectives: to identify potential target audiences for adolescent vaping prevention campaigns and to describe the psychographics, media use, and interests of these higher-risk youth to inform campaign planning. First, we sought to define potential target audiences by applying a peer crowd audience
  • 7. segmentation approach. Peer crowds are macro-level subcul- tures with shared interests, values, and norms47,48 which are associated with adolescent and young adult health behaviors49-57 and have served as the basis for targeted health interventions.58-64 For example, the Commune campaign target- ing Hipster peer crowd young adults resulted in reductions in cigarette smoking associated with stronger anti-tobacco atti- tudes among those recalling the campaign,58,62 whereas engage- ment with the Down and Dirty campaign was associated with stronger anti-chewing tobacco attitudes and lower odds of cur- rent use among Country peer crowd teens.61 In this study, we examined vaping behavior for 5 adolescent peer crowds previ - ously established in the literature: Alternative (counterculture, value creativity and uniqueness), Country (patriotic, value hard work and being outdoors), Hip Hop (confident, value over- coming struggles and proving themselves), Mainstream (future-oriented, value organization and stability), and Popular (extroverted, value socializing and excitement).47,49,50,52,54,55,61 After identifying the highest risk peer crowds, we sought to create a profile of these audiences by examining their broader health risk profiles, psychographics (social prioritization and personal values), digital behaviors (social media and smart- phone use), and interests (television shows and events). With this information, we aimed to identify and describe segments of adolescents most in need of targeted vaping interventions to provide clear guidance for health message development and media targeting. Methods Sample and design We collected cross-sectional online survey data from high
  • 8. school students ages 13 to 19 living in the U.S. state of Virginia (N = 1594). Participants were recruited from November 2017 to January 2018 using paid Instagram and Facebook advertise- ments that directed interested individuals to a screener to determine eligibility (13-19 years old, current high school stu- dent, and Virginia resident). Eligible youth were invited to par- ticipate in the full survey and provided electronic assent (ages 13-17) or consent (ages 18-19). We delivered a parental opt- out form via email for participants ages 13 to 17. Qualified participants who completed the full survey received a US$10 electronic gift card incentive. We implemented numerous fraud prevention and detection measures to maximize data integrity, including concealing eligibility criteria during screening, col - lecting email addresses to prevent duplicate completi ons, and reviewing responses for inconsistencies. Chesapeake IRB approved the study (No. Pro00023204). Measures To address our research objectives, we examined participant demographics; current vaping, tobacco, and other substance use; peer crowd identification; 2 psychographic measures, namely, social prioritization65 and personal values; social media Stalgaitis et al 3 and smartphone use; and television show and event preferences. Demographics. Participants provided their birthdate, from which we calculated their age. Participants also indicated their gender (male, female) and race/ethnicity (Hispanic, non-His- panic White, non-Hispanic Black, non-Hispanic Asian-Pacific
  • 9. Islander, and non-Hispanic other including multiracial and American Indian or Alaska Native). Past 30-day vape use. Participants reported the number of days in the past 30 days on which they used e-cigarettes or vapes, with response options of 0, 1 or 2, 3 to 5, 6 to 9, 10 to 19, 20 to 29, and all 30 days. To mirror commonly reported statistics, we examined both any current vaping (1-30 days) and frequency of vaping defined as occasional use (1-19 days) or frequent use (20-30 days).66 Past 30-day tobacco and substance use. Participants also reported the number of days in the past 30 days on which they used cigarettes; cigars, cigarillos, and little cigars (cigar products); smokeless tobacco; hookah; alcohol; marijuana; and prescrip- tion medication without a prescription. Those who reported any past 30-day use were considered current users of that item. Peer crowd identif ication. Participants completed Rescue Agency’s I-Base Survey®, a photo-based tool that measured identification with 5 peer crowds: Alternative, Country, Hip Hop, Mainstream, and Popular. The I-Base Survey has identi- fied consistent patterns of peer crowd prevalence and health risks in adolescents across the United States.49-52,55,57,61,64 In brief, participants viewed a grid of 40 photos of unknown female adolescents and selected 3 who would best and 3 who would least fit with their main group of friends; they then repeated the process with male photos. Photos were presented in random order to each participant to reduce order effects, and represented a mix of races/ethnicities and peer crowds deter- mined through prior qualitative research. Participants earned positive points for the peer crowds of photos selected as the best fit and negative points for those selected as the least fit, resulting in a score ranging from –12 to 12 for each of the 5
  • 10. crowds. For analyses, we assigned participants to each crowd with which they had at least some identification, defined as a score of 1 or more on the I-Base Survey for that crowd. Partici- pants could be assigned to more than 1 peer crowd as they could score positively for multiple crowds. Social prioritization index. Participants completed the social prioritization index (SPI), a validated measure of the degree to which an individual places importance on their social life that is associated with young adult cigarette use.58,59,65 The SPI included 13 questions: 8 items wherein participants selected 1 response that best described them from a pair (up for anything/ pick and choose what to do, outgoing/low-key, center of attention/lay low, street smart/book smart, partier/studier, wing it/plan it out, the carefree one/the responsible one, in a picture I . . . strike a pose/smile big); 3 true or false items (In groups of people, I am rarely the center of attention; I have considered being an entertainer or actor; I can look anyone in the eye and tell a lie with a straight face); 1 item asking how many nights they went out for fun in the past week (0-1, 2-3, 4-5, 6-7 nights); and 1 item asking how late they typically stayed out when they went out for fun (9:59-10:59 pm, 11:00 pm-12:59 am, 1:00- 2:59 am, 3:00 am or later). To calculate the SPI score (range: 0-17), participants received 1 point for each socially oriented selection for the 8 descriptive pairs and 3 true/false questions, and received 0 points for selecting 0-1 nights per week or 9:59- 10:59 pm, 1 point for 2-3 nights per week or 11:00 pm-12:59 am, 2 points for 4-5 nights per week or 1:00-2:59 am, and 3 points for 6-7 nights per week or 3:00 am or later. Personal values. Participants viewed 26 personal values state- ments (e.g., I think it is more important to live in the moment than focus on the future) and rated each on a 5-point Likert-
  • 11. type scale from 1 (strongly disagree) to 5 (strongly agree). Past 7-day social media use. Participants reported if they had consumed or created content on 6 social media platforms in the past 7 days: Facebook, Instagram, Twitter, Tumblr, Snapchat, and Pinterest. Lifetime smartphone use. Participants were asked if they had a smartphone, and if so, if they had ever used their smartphone to engage in 9 different activities (e.g., listen to an online radio or a music service such as Pandora or Spotify; watch movies or TV shows through a paid subscription service like Netflix). Television show preferences. Participants selected all television shows they regularly watched from a list of 24 broadcast and streaming shows popular with youth (e.g., 13 Reasons Why, Ridiculousness). Event preferences. Participants selected all events they regularly attended from a list of 25 leisure time events youth might attend (e.g., sports games, high school dances). Statistical analysis Respondents were required to complete the survey, so no data were missing. Data were weighted to the gender, race/ethnicity, and urban/rural demographics of Virginia teens for all analy- ses. As a first step, we ran weighted and unweighted frequen- cies and means for demographic measures. To address our first objective of identifying which adoles - cents were at the greatest risk, we used chi-square tests to com- pare the rates of current vaping and vaping frequency among those who did and did not identify with each crowd, using follow-up z tests with Bonferroni correction to identify specific
  • 12. 4 Tobacco Use Insights significant differences. To confirm that associations persisted while controlling for demographics, we ran separate binary and multinomial logistic regression models for each peer crowd, with a single peer crowd’s score (range: –12 to 12) predicting odds of current vaping, or of occasional or frequent vaping, while controlling for age, gender, and race/ethnicity. We also ran binary logistic regression models for each crowd to predict odds of any current cigarette, cigar product, smokeless tobacco, hookah, alcohol, and marijuana use, and any current prescrip- tion medication misuse, to understand the broader risk profile of the peer crowds. We ran separate models for each peer crowd to avoid multicollinearity associated with including all 5 scores in a single model. After identifying 2 peer crowds at elevated risk for vaping, we addressed our second objective of developing interest-based profiles of these potential target audiences by describing their psychographics (SPI and personal values), social media and smartphone use, and television and event preferences. We first compared frequencies and means for those who did and did not identify with the 2 crowds of interest, using chi-square tests and t tests to identify significant differences. Then, within the 2 peer crowds, we compared frequencies and means between current vape users and non-users, using chi-square tests and t tests to identify significant differences. This approach allowed us to identify the characteristics of the 2 peer crowds of interest to inform campaign content and media targeting, as well as to hone in on psychographics and interests that specifically char - acterized current vape users within the higher-risk crowds. Due to the relatively small subset of participants who were fre- quent vape users, we focused on any current use to improve the
  • 13. reliability of results. Tables present items that differed signifi - cantly between groups in at least 1 analysis and had endorse- ment rates above 5.0%. Results The weighted mean age of the sample was 16.47 years, and about half identified as female (50.8%) and as non-Hispanic White (55.3%) (Table 1). The most common peer crowd iden- tifications were Popular (63.1%) and Mainstream (62.6%). Race/ethnicity and gender breakdowns differed by crowd (Supplemental Appendix Table 1). Consistent with 2018 National Youth Tobacco Survey results,2 20.6% of Virginia high school students in our sample currently vaped (Table 2). A significantly greater proportion of those with any Hip Hop peer crowd identification currently vaped (25.4%) than those with no Hip Hop identification (18.0%, P < .001). In binary logistic regression models using each peer crowd score (–12 to 12) to predict odds of current vaping while controlling for demographics, a 1-point increase in the Popular score was associated with a 4% increase in odds of current vaping, whereas a 1-point increase in the Hip Hop score was associated with a 10% increase. Further differentiating current vape users in the sample, 17.0% were occasional vape users (1-19 days in the past 30 days) and 3.7% were frequent users (20-30 days). Those with any Hip Hop identification reported higher rates of occasional vaping (21.2%) than others (14.6%, P < .05). Although rates of frequent vaping did not differ significantly for any peer crowd, stronger Hip Hop identification was associated with greater odds of both occasional and frequent vaping. Stronger Popular identification was associated with greater odds of occasional vaping only. In addition, stronger Hip Hop identification was
  • 14. associated with greater odds of current cigarette, cigar product, hookah, alcohol, and marijuana use, whereas stronger Popular identification was associated with lower odds of use for many products. Based on the chi-square tests and logistic regression results, we identified the Hip Hop and Popular peer crowds as being at elevated risk for vaping. We then characterized the psycho- graphics (Table 3), social media and smartphone use (Table 4), and interests (Table 5) of Hip Hop and Popular youth in gen- eral, as well as Hip Hop and Popular current vape users in particular. Overall, Hip Hop participants were social, trendy individu- als interested in hip hop/rap music and sports. Compared with those with no Hip Hop identification, Hip Hop youth had higher SPI scores, in particular describing themselves as par - tiers, street smart, and carefree (Table 3). Hip Hop youth more often agreed that they make decisions quickly, are fashionable, are social people with lots of friends, and are tougher than most people. In contrast, they less often agreed that they are patri - otic, good students, care what others think about them, care about keeping their bodies free from toxins, and follow the rules. A greater proportion of Hip Hop youth used Snapchat in the past week and used their smartphones to look up sports scores or analyses than those with no Hip Hop identification (Table 4). Many TV shows more often endorsed by Hip Hop youth revolved around hip hop/rap musical interests, such as Love & Hip Hop, The Rap Game, and Wild ’N Out (Table 5). Similarly, Hip Hop youth more often indicated that they regu- larly attend hip hop concerts and dance clubs than others, as well as basketball and football games. Characteristics of vape users within the Hip Hop peer crowd largely reflected an amplification of the broader crowd’s profile. Hip Hop vape users had higher SPI scores than non-
  • 15. users within the crowd, and they described themselves as par- tiers, street smart, carefree, and up for anything (Table 3). They more often agreed that they are fashionable, use their clothes to express their identity, and are tough, and less often agreed that they follow the rules, follow tradition, and care about keeping their bodies free from toxins than non-users. A greater propor- tion of Hip Hop vape users reported using Snapchat, Instagram, and Twitter in the past week than non-users (Table 4). Hip Hop vape users also more often reported using their smart- phones to look up sports scores and analyses, stream music, and make video calls than non-users. Hip Hop vape users more often reported watching 2 cartoon shows, The Boondocks and Bob’s Burgers, than non-users (Table 5). Similar to the overall Stalgaitis et al 5 crowd, a greater proportion of Hip Hop vape users indicated that they attend dance clubs, hip hop concerts, basketball games, and football games than non-users. Popular youth shared some characteristics with Hip Hop youth, but also differed in key ways. Although Popular and Hip Hop youth both reported higher SPI scores than others, the specific SPI items they endorsed often differed (Table 3). Though both Hip Hop and Popular youth described them- selves as partiers, Popular youth also described themselves as the center of attention, outgoing, and up for anything, which were not significant in Hip Hop analyses. Similar to Hip Hop youth, Popular youth more often agreed that they are fashion- able and are social people with lots of friends. However, Popular youth also more often agreed that they care about being good students, keeping their bodies free from toxins, and being patriotic, items with which Hip Hop youth less often agreed.
  • 16. Popular youth also more often agreed that family is important, that they try to follow tradition, and that they are religious than other youth. Popular youth more often reported using Instagram, Snapchat, and Twitter than other youth and more often used their smartphones to look up sports scores or analy- ses and to stream music or video content (Table 4). Compared with others, Popular youth more often reported watching teen dramas, including 13 Reasons Why, Jane the Virgin, Pretty Little Liars, and Riverdale (Table 5). Sports were favored by Popular youth, as they more often reported attending basketball, foot- ball, baseball, and soccer games than others. They also more often reported attending church events, community service events, high school dances, and pop and country music concerts. Popular vape users shared many traits with the broader Popular crowd as well as with Hip Hop vape users. Similar to Hip Hop vape users, Popular vape users reported higher SPI scores than non-users, describing themselves as outgoing, Table 1. Unweighted and weighted sample descriptive statistics.

Similar to the broader Popular crowd, Popular vape users more often reported attending sports games, high school dances, and concerts than non-users, though they less often reported attending church events. Discussion This study identified a subset of adolescents at the greatest risk for vaping, and the psychographic characteristics and interests that should inform the creation of targeted health communica- tions messages and media delivery strategies for these youth. The Hip Hop and Popular peer crowds were at the greatest risk for current vaping, aligning with earlier representative data from Virginia and similar studies of young adults.52,53,56 Interestingly, although both crowds were at increased risk for current vaping, their broader risk profiles diverged, indicating a need for differentiated health messaging for the 2 crowds. Hip Hop youth had greater odds of vaping frequently, which may indicate an escalation to nicotine addiction, and were more likely to use other tobacco products and substances. Popular youth, however, were at increased risk for occasional vaping only, with reduced risk for several other substances including cigarettes. Understanding the psychographics and interests of Hip Hop and Popular youth, and Hip Hop and Popular current vape users in particular, provides insights for health communi - cations campaign development and hints at possible explana- tions for differential risk by crowd. Hip Hop and Popular youth and current vape users reported higher mean SPI scores than other youth, and endorsed personal values related to being fashionable and sociable. These findings paint a psychographic portrait of Hip Hop and Popular youth and current vape users as individuals who care about their social lives, are trend sensi - tive, and are strongly influenced by their social environments.
  • 256. This portrait aligns with vape marketing campaigns, which often feature celebrities, associate vaping with socializing and partying, and use sleek, modern designs reminiscent of trendy technology such as iPhones,37,67-69 all of which likely appeal to the youth described here. To effectively counter industry mar- keting and media depictions that may appeal to Hip Hop and Popular adolescents, health educators must create relevant messaging that breaks the connection between vaping and social status or trendiness, and motivates youth to reconsi der vaping as a key feature of their social lives. Furthermore, as cur- rent vape users in this study cared less about following rules and protecting their bodies from toxins than non-users, cam- paign messaging must look beyond authoritative tones and typical scare tactic messaging to cultivate a socially influential brand that can persuade higher-risk youth to avoid vaping by speaking directly to their priorities and values. Hip Hop and Popular adolescents and current vape users also reported extensive smartphone and social media use, in particular the use of Instagram, Snapchat, sports analysis sites, and video/music streaming services. Heavy social media use may contribute to adolescent vaping as user- and industry- generated vaping content abounds across platforms,70-74 and early research suggests that heavier social media use and expo- sure to vape advertisements on social media are associated with willingness and intentions to vape.75 Given the known associa- tion between exposure to online tobacco marketing and adoles- cent tobacco initiation and progression,76,77 heavy social media use among Hip Hop and Popular adolescents may further explain why these youth vape. At the same time, these findings can guide health communicators in selecting relevant cam- paign channels and delivering content via targeted advertise-
  • 257. ments. Vaping prevention campaigns must meet higher-risk adolescents where they are to deliver messaging to the target audience using the cutting-edge ad-targeting technology employed by commercial advertisers. Although not yet ubiqui - tous in public health, the targeted placement of paid campaign advertising has been successfully applied to deliver health com- munications to intended audiences for initiatives including the U.S. Food and Drug Administration’s The Real Cost general market and Fresh Empire Hip Hop adolescent tobacco educa- tion campaigns.35,61,78,79 In addition, to counter the abundance of pro-vaping content youth encounter online, health commu- nication campaigns must cultivate active, appealing social media presences to establish themselves as relatable and trust- worthy social influencers and interject tailored prevention mes - saging into the pro-vaping social media environments of higher-risk youth.80,81 Finally, Hip Hop and Popular youth and current vape users reported specific television and event preferences. Although vaping is currently rare in television programming,82,83 exposure to vape advertisements on television and to vaping in other forms of media including music videos is common and may promote positive attitudes toward vaping among youth.84-89 Although it is unclear if Hip Hop and Popular adolescents are disproportionately exposed to vape advertisements or onscreen vaping, continued monitoring is warranted to track how vaping is depicted over time and if exposure to vaping in media is asso- ciated with risks similar to that of exposure to cigarette smoking in movies.90 In addition, little is known about vape industry sponsorship or promotion at events, an important topic for future work given the tobacco industry’s historical use of events

Stalgaitis et al 13 for product promotion.91,92 Although less is known about how television and event preferences may influence vaping ri sk, this information is incredibly useful to health educators for cam- paign tailoring and media targeting. Interests can be used to build media targeting profiles that concentrate message delivery and dosage on those most at risk, increasing chances for suc- cessful attention and persuasion. Television preference data can inform media buys,93 identify potential influencer partnerships, and reveal opportunities to engage with the target audience about relevant televised events.81 Event preference data can inform the selection of relevant settings for advertisements and identify opportunities for in-person engagement with the target audience. With this wealth of information, health educators can develop targeted health communication interventions that effectively reach and persuade higher-risk adolescents. Although the Hip Hop and Popular peer crowds shared some psychographics and preferences, differences between the crowds indicate that separate campaigns are necessary. In par - ticular, different messaging approaches are needed to appro- priately address the more frequent, established nature of vaping among Hip Hop youth, who may require cessation resources, and the less frequent, possibly social nature of vap- ing among Popular youth. Experimental studies have demon- strated the promise of peer crowd-targeted smoking prevention messaging,94-96 and evaluation studies of peer-crowd-targeted campaigns reveal success in addressing cigarette and smoke- less tobacco use.58-62,64 Peer crowd targeting may also be a means of more effectively addressing tobacco use disparities. Previous literature suggests that non-Hispanic White youth are at the greatest risk for vaping,23-25,27 but this study indi- cates that the Hip Hop peer crowd, which overrepresents racial/ethnic minorities (Supplemental Appendix Table 1),50-
  • 259. 52,54 is at the greatest risk for frequent vaping, identifying a higher-risk group that might otherwise be missed by cam- paigns using demographic segmentation. This study provides a preliminary insight into who these youth are, what they care about, and the media they consume; future research must test potential campaign messages with youth from the targeted peer crowd to ensure that tailored content resonates and moti - vates positive behavior change. Limitations It is important to note several limitations of this study. Generalizability is unclear as we surveyed a convenience sam- ple recruited via social media from a single state, although peer crowd risk findings did align with previous observations from varied samples and locations.52,53,55,56 We did not collect vape brand preferences, and did not distinguish between vaping nicotine, tetrahydrocannabinol (THC) or marijuana products, and flavors only, which should be explored to determine if users of different products have unique characteristics and interests. We also cannot discern causality, such as whether any of these psychographic characteristics or interests predisposed teens to increased interest in vaping, or if targeted industry marketing or other factors may have contributed to disparities. Conclusions Tackling adolescent vaping requires understanding who is at the greatest risk and how to reach them with relevant, persuasive messaging. Although current vaping is increasingly common among U.S. adolescents, risk is not evenly distributed, and pre- vention efforts should rely on psychographic segmentation, audience tailoring, and media targeting to effectively and effi - ciently reach higher-risk adolescents.45 Although establishing a deeper understanding of the psychographics and interests of
  • 260. higher-risk adolescents may appear burdensome, in fact it is nec- essary to ensure that limited public health funds are spent on the populations facing the greatest challenges,46 particularly in today’s online media environment where platform targeting tools cater toward advertisers who know the interests of their audiences. Our findings provide a detailed portrait of adoles - cents who are at increased risk for current vaping, information which should directly inform health communication campaign planning. Future campaigns should incorporate our findings to create messages relevant to the psychographics and risk profiles of these youth, which are delivered using carefully selected media strategies reflecting the greatest opportunities to reach the target audience efficiently. Addressing the urgent adolescent vaping crisis requires looking deeper than demographics to understand and leverage knowledge about who adolescent vape users are and what they care about, to create health communications cam- paigns that appeal to and persuade those at the greatest risk.

Venechuk3 Received: 12 June 2019 / Accepted: 2 August 2019 / Published online: 24 August 2019 © Springer Science+Business Media, LLC, part of Springer Nature 2019 Abstract Schools are important contexts for adolescent health and health- risk behaviors, but how stable is this relationship? We develop a conceptual model based on Ecological Systems Theory describing the changing role of schools for adolescent health outcomes—in this case, teen e-cigarette use. To examine this change, we fit Bayesian multilevel regression models to two-year intervals of pooled cross-sectional data from the 2011–2017 U.S. National Youth Tobacco Survey, a school- based study of the nicotine use behaviors of roughly 65,000 middle and high school students (49.5% female; 41.1% nonwhite; x ̄ age of 14.6 ranging from 9 to 18) from over 700 schools. We hypothesized that school-level associations with student e-
  • 281. cigarette use diminished over time as the broader popularity of e-cigarettes increased. Year-specific variance partitioning coefficients (VPC) derived from the multilevel models indicated a general decrease in the extent to which e-cigarette use clusters within specific schools, suggesting that students across schools became more uniform in their propensity to vape over the study period. This is above and beyond adjustments for personal characteristics and vicarious exposure to smoking via friends and family. Across all years, model coefficients indicate a positive association between attending schools where vaping is more versus less common and student-level odds of using e-cigarettes, suggesting that school contexts are still consequential to student vaping, but less so than when e- cigarettes were first introduced to the US market. These findings highlight how the health implications of multiply-embedded ecological systems like schools shift over time with concomitant changes in other ecological features including those related to policy, culture, and broader health practices within society. Though not uniformly reported in multilevel studies, variance partitioning coefficients could be used more thoughtfully to empirically illustrate how the influence of multiple developmentally-relevant contexts shift in their influence on teen health over time. Keywords Adolescence ● Schools ● E-Cigarettes ● Multilevel Introduction Use of electronic cigarettes (“e-cigarettes”) among adoles- cents has rapidly proliferated. Between 2011 and 2015, the prevalence of current e-cigarette use climbed from 0.6% to 5.3% among US middle schoolers, and from 1.5% to 16% among high schoolers (Singh et al. 2016a).

In addition to the health risks associated with vaping (Chun et al. 2017; El-Hellani et al. 2018; Larcombe et al. 2017; Moheimani
  • 284. et al. 2017), the link between vaping and conversion to smoking has driven interest in how the traits of adolescents and the contexts they engage with most are associated with vaping. Schools have long been recognized as critical contexts that shape youth health-risk behaviors (Alexander et al. 2001; Bonell et al. 2013a; Bonell et al. 2013b; Ellickson et al. 2003), including vaping (Corsi and Lippert 2016; Lippert 2018). However, recent population-wide trends call to question whether adolescent e-cigarette use has remained concentrated in particular schools or if the likelihood of vaping has become more uniform among students across schools. Responding to this question, the current study draws on Ecological Systems Theory (Bronfenbrenner 1977; Bronfenbrenner and Morris 1998) to investigate two research questions: (1) How has the school clustering of vaping—a measure of the extent to which schools differ based on their prevalence of student e-cigarette use— changed between 2011 and 2017 as the population-wide prevalence of youth vaping increased? (2) How is the pre- valence of school-level e-cigarette use associated with a student’s odds of vaping net of key influences from one’s family and peer group? To answer these questions, pooled cross-sectional data from the 2011 to 2017 National Youth Tobacco Surveys (NYTS) are used to decompose variance partitioning coefficients from multiyear multilevel regres- sion models of students nested within schools across the US. Variance partitioning components (VPC) provide an empirical estimate of school influence and a measure of the similarity of e-cigarette use or abstinence between students within schools. Thus, year-specific VPCs allow an assess- ment of change in the school clustering of teen vaping over a period when adolescent e-cigarette use emerged as a population health concern.
  • 285. The Ecology of Youth Vaping According to Ecological Systems Theory, youth develop- ment is guided by influences across multiply-embedded systems. These include features within the exosystem and macrosystem – broad societal influences such as public policy, culture, and population-wide trends—and the microsystem, or those institutions and relationships nearest to youth such as schools, families, and peers. Connections between and within the two systems are made via the mesosystem, a “system of systems” comprised of the reci- procal relationships among ecological features, such as federal policies in the exosystem that alter family- or school-based processes in the microsystem. A fifth dimen- sion of the ecological model is the chronosystem, which reflects the developmental implications of both an indivi - dual’s stage in the life course and the sociohistorical context within which ecological systems are embedded and experienced. This aspect of ecological theory is critical for the purposes of this study, though the chronosystem has received less attention than features within the microsystem (Tudge et al. 2016). Schools and Youth Health Behaviors The association between school contexts and youth vaping is made clearer by the conceptual model developed by Frohlich and colleagues (Abel and Frohlich 2012; Frohlich et al. 2002; Frohlich, Corin and Potvin 2001), a complement to ecological theory. The model describes the interplay between contextual and agentic factors that produce—and are produced by—community features. According to this model, health behaviors are viewed as “generated prac- tices,” or products of both structural conditions and self- determination. This perspective is rooted in Weber’s dis-
  • 286. tinction between “life chances”—features of social structure that free or constrain human agency, and “life choices”— the health behaviors enacted by individuals responding to structural demands and opportunities (Hays 1994). Abel and Frohlich (2012) elaborate on self-determination by describing it in terms of its contextual embeddedness, or the “socially-structured development, acquisition, and applica- tion of structural and personal resources by individuals in a given context,” (p. 239). Under this view, the consequences of human agency can be understood as both the healthy and unhealthy practices among individuals responding to con- textual demands and opportunities, which reinforces the “collective health lifestyles” practiced among community members (Frohlich, Corin and Potvin 2001). Like ecological theory, this model acknowledges the developmental importance of school environments and the reciprocal nature of relationships among features within and between ecological systems. Evidence from countless stu- dies lends empirical support to these claims. Given the recency of vaping as a population health concern much of this research is focused on other related outcomes, such as conventional tobacco use. These studies show that students —even low-risk students—attending schools with high rates of smoking are themselves more likely to smoke (Alexander et al. 2001; Leatherdale and Manske 2005). The association between school-level factors and adolescent smoking has proven robust to a range of confounders at the individual, family, and neighborhood levels (Dunn et al. 2015). Evidence from a limited number of studies on schools and e-cigarette use also show that youth attending 1900 Journal of Youth and Adolescence (2019) 48:1899–1911
  • 287. schools where vaping is common are more likely to vape (Corsi and Lippert 2016). The mechanisms linking schools to youth health-risk behaviors are not entirely clear, but may include norms and the provision of both social and material resources. Norms include the health beliefs, attitudes, and policies that inhere within school communities. While school-based policies have shown inconsistent and often null associations with adolescent health behaviors, especially smoking (Coppo et al. 2014; Galanti et al. 2014), the beliefs and attitudes held among one’s schoolmates have been shown to corre- late with one’s own beliefs, attitudes, and behaviors. For instance, there is a persistent and inverse association between average school-level student attainment and attendance and student-level substance use (Bonell et al. 2013b), suggesting that school environments supporting norms that emphasize student achievement discourage behaviors incompatible with academic success. Conversely, youth attending schools with lenient norms risk developing beliefs and attitudes compatible with substance use. For example, youth attending schools with high versus low rates of vaping are more likely to believe that e-cigarettes are harm-free and less addictive than combustible cigarettes, irrespective of their actual e-cigarette use (Lippert 2018). In schools with lenient norms that fail to correct students’ misconceptions of the risks associated with e-cigarettes, pupils are more likely to have access to social and material resources needed to vape. This includes peer modeling of vaping behaviors and use of peers’ vaping devices. As a learned behavior, initiating e-cigarette use is facilitated by peer modeling and demonstrations. Indeed, a recent mixed- methods study of adolescents and young adults found that one-third of the sample first began experimenting with e- cigarettes because an e-cigarette using friend introduced
  • 288. them to the practice (Kong et al. 2015). Analysis of quali - tative data from the same study suggests that when one member of a peer group acquires an e-cigarette, offers to use the device are soon made to other group members. Other learned behaviors associated with e-cigarettes include performative aspects of use, such as “vaping tricks” demonstrated by friends or a desire to “look cool,” espe- cially for younger adolescents (Roditis et al. 2016). Given the social functions of e-cigarette use it is not surprising that a recent study showed leisure time activities among e- cigarette using teens is often centered on a mutual interest in vaping activities (Evans-Polce et al. 2018). A Model for Changing School-Level Influence The temporal stability of the link between school features and youth health behaviors has not been widely investi- gated. Ecological Systems Theory acknowledges that the influence of such systems on youth development is conditioned by the sociohistorical context in which they are experienced (Bronfenbrenner and Morris 2006). In the case of adolescent e-cigarette use, recent changes in the exo and macrosystems warrant closer inspection of how the role of schools has changed for teen vaping. These cross-system relationships are described in Fig. 1. Following the ecological model, adolescent e-cigarette use is considered a product of factors found across multiply- embedded systems, namely the microsystem (school, family, peer, and individual factors) and exo or macro- systems (policy, media, culture, and population-wide trends in e-cigarette use). The conceptual model in Fig. 1 under- scores the influence that features within the exo and mac- rosystems have on both schools as well as individual behaviors. At the level of the exosystem, state and federal
  • 289. policies on e-cigarettes have a bearing on both individual consumption (e.g., new minimum age restrictions for pur- chase) and school functionings (e.g., regulations on e- cigarette sales near schools). At the level of the macro- system, cultural shifts—the population-wide rise in e- cigarette use; youth-targeted marketing campaigns—not only have direct influences on youth behaviors, but they also modify the association between school features and youth behaviors. For instance, the role that peers play in disseminating beliefs and attitudes about the safety and benefits of vaping (e.g., looking cool or demonstrating adult-like behavior) could be augmented, or even sup- planted by, messages circulating throughout social media within the macrosystem. Indeed, recent evidence shows that advertising of e-cigarettes to adolescents has climbed dra- matically over recent years (Duke et al. 2014; McCarthy 2016), and exposure to such advertising, including celebrity endorsements via social media, is linked to higher odds of Fig. 1 Conceptual model of the interdependent association between schools and e-cigarette use Journal of Youth and Adolescence (2019) 48:1899–1911 1901 teen use (Camenga et al. 2018; Hammig, Daniel-Dobbs and Blunt-Vinti 2017; Pasch et al. 2018; Phua, Jin and Hahm 2018; Singh et al. 2016b). Under this scenario, the impor- tance of schools to teen vaping could have diminished over time as analogous influences from other ecological systems became more pronounced—a phenomenon we refer to as system drift. Conversely, other changes in the exo and macrosystems
  • 290. could have enhanced the relevance of schools to teen vaping via the mechanisms described earlier. Recently expanded regulations on e-cigarettes by the FDA (U.S. Food and Drug Administration 2016) imposed mandatory minimum age requirements on e-cigarette sales, even though research shows that sales of e-cigarettes to minors is still common (Levinson 2018). Should e-cigarettes become more difficult for youth to purchase, adolescents will rely more on peer- mediated access organized within schools, raising the importance of schools to adolescent vaping. Additionally, important shifts in how teens vape could have strengthened the role that schools played in facilitating the initial emer - gence of adolescent e-cigarette use. Manufacturers of technologically-novel “next-gen” e-cigarette devices have targeted teenagers in their marketing (Chu et al. 2018) and to great effect, as devices like Juul have become popular among youth (Krishnan-Sarin et al. 2019). The evolution of vaping devices over time could have required localized peer-to-peer demonstrations of use, peer-mediated access to vaping materials, and flexible school-based cultural norms that permit vaping, bringing schools back into focus as the broader prevalence of teen vaping climbed. Current Study While either scenario—diminishing or increasing school- level influences—is possible, no empirical attention has been given to how the clustering of adolescent e-cigarette use within schools has shifted over recent years. Respond- ing to the lack of attention to shifting school influences on teen health, Ecological Systems Theory and conceptual models of school environments and adolescent health (Abel and Frohlich 2012; Frohlich et al. 2002; Frohlich, Corin and Potvin 2001) are used to address the following research questions: (1) How has the school clustering of vaping changed between 2011 and 2017 as the population-wide
