4. Instruments
• Hatch (2002) and Marshall and Rossman (1995)
contend that in-depth interviewing, participant
observation and reviewing of documents are the
primary data gathering strategies in qualitative
research.
• Bassey (1999) and Merriam (1998) have argued
that data collection in case study research mainly
involves interviewing, observing and analyzing
documents.

5. Instruments
• Patton (1990) argues, "no single source of
information can be trusted to provide a
comprehensive perspective on the
phenomenon…
• Each type of data source has strengths and
weaknesses, researchers combine different
sources to validate and cross-check findings
(p. 244).

6. Interviewing
• "An interview is a conversation, usually between
two people. But it is a conversation where one
person-the interviewer-is seeking responses for a
particular purpose from the other person: the
interviewee" (Gillham, 2000b, p. I).
• It is a tool for gathering information (Denscombe,
1998).
• Understanding the experience of people and what
meanings they derive from those experiences is at
the heart of in- depth interviewing (Seidman, 1998)

7. Interviewing
The purpose of interviewing is to find out what is in
and on someone else's mind ... we interview people
to find out from them those things we cannot
directly observe ... we cannot observe feelings,
thoughts, and intentions. We cannot observe
behaviors that took place at some previous point in
time. We cannot observe situations that preclude
the presence of an observer. We cannot observe
how people have organized the world and the
meanings they attach to what goes on in the world.
We have to ask people questions about those things.
Patton (1 990, p. 278)

8. Interviewing
• Interviews fall into three categories : structured,
semi structured and open-ended interviews (B
erg, 2001 ; Marshal! & Rossman, 1995).
• This categorization is based on the degree to
which it is structured (Bogdan & Biklen, 1998;
Gillham, 2000b; Marshal! & Rossman, 1995) and
the extent to which the interviewee is allowed to
shape the interview's content (Bogdan & Biklen,
1998).

9. Instruments
• In addition to face to face interviews and
telephone interview, group interviewing or
focus group interviewing is among many other
specific types of interviews that are used in
research (Gillham, 2000a, pp. 81-89).

10. structured interview
• The structured interview is used when the
researcher knows the ground that he would
cover during the interviews, and he/she further
assumes that questions included in the interview
schedule would seek all or nearly all the
information related to the topic of study (Berg,
2001).
Dr. Chandana Kasturiarachchi-

10

11. Unstructured or Open-ended
interviews
• unstructured or open-ended interviews, the
researcher does not assume that he knows
what ground to cover and, therefore, he
would not have a set of questions to ask.
Dr. Chandana Kasturiarachchi-
chacmb@gmail.com
11

12. Semi- structured interviews
• Semi- structured interviews, although there is a
predetermined set of questions, the interviewers
are free, in fact expected, to probe beyond the
answers to these questions.
Dr. Chandana Kasturiarachchi-
chacmb@gmail.com
12

13. Focus Group Interviews
• In this type of interview, a small group of people
is brought together in order to explore their ideas
about a particular topic (Denscombe, 1998)
• Berg (2007) highlights many advantages of focus
group interviewing. Among these, most notable
are: "it permits the gathering of a large amount
of information from potentially large group of
people in relatively short period of time" (Berg,
2007, p. 148)
Dr. Chandana Kasturiarachchi-

14. Participant Observation
• In the participant observation process, "the
researcher carefully observes, systematically
experiences, and consciously records in detail the
many aspects of a situation" (Glesne, 1999, p. 46)
.
Dr. Chandana Kasturiarachchi-

15. Participant Observation
• One has to spend a considerable amount of time
in the setting for observation (Marshall &
Rossman, 1995), this method of data collection is
very basic to all qualitative studies (Hatch, 2002;
Marshall & Rossman, 1995; Merriam, 1998;)
• because it allows the researcher to experience
reality from the participants ' perspectives
(Denscombe, 1998; Hatch, 2002; Merriam, 1998;
Patton, 1990) .

16. Documents
• Documents include a wide range of material :
photographs, videos, memos, diaries,
memorabilia of all sorts (Bogdan & Biklen,
1998), logs, announcements, formal policy
statements (Marshall & Rossman, 1995),
annual reports, and so on.

17. Documents
• Bogdan & Biklen (1998) have identified three
main types of documents : personal, official
and popular culture documents.

18. Questionnaire
• A questionnaire is a set of questions given to
participants on paper to be answered by them. In
qualitative research, a questionnaire is used to
learn about characteristics, attitudes or beliefs
among a particular group or a sample population
(Marshall & Rossman, 1995).
• But the usefulness of the questionnaire is limited
to the fact that the researcher would have to rely
completely on the respondents' honesty and
accuracy of their answers (p. 96)
Dr. Chandana Kasturiarachchi-
chacmb@gmail.com
18

19. Questionnaire
• The type of questions contained in a
questionnaire is mostly factual, straightforward
and, to some extent, open-ended (Gillham,
2000b; Marshall & Rossman, 1995).
• They allow the collecting of small amounts of
data from a large group within a short period of
time; they are relatively easy to analyze; and,
they are impersonal.

21. Introduction
• Interviews are particularly useful for getting the
story behind a participant's experiences. The
interviewer can pursue in-depth information
around a topic. Interviews may be useful as follow-
up to certain respondents to questionnaires, e.g.,
to further investigate their responses. Usually
open-ended questions are asked during interviews.

22. Design your interview
• Before you start to design your interview
questions and process, clearly articulate to
yourself what problem or need is to be
addressed using the information to be gathered
by the interviews. This helps you keep clear
focus on the intent of each question.
Dr. Chandana Kasturiarachchi-
chacmb@gmail.com

23. Types of Interviews
• Informal, conversational interview - no predetermined questions are
asked, in order to remain as open and adaptable as possible to the
interviewee's nature and priorities; during the interview, the
interviewer "goes with the flow".
• General interview guide approach - the guide approach is intended to
ensure that the same general areas of information are collected from
each interviewee; this provides more focus than the conversational
approach, but still allows a degree of freedom and adaptability in
getting information from the interviewee.
• Standardized, open-ended interview - here, the same open-ended
questions are asked to all interviewees (an open-ended question is
where respondents are free to choose how to answer the question, i.e.,
they don't select "yes" or "no" or provide a numeric rating, etc.); this
approach facilitates faster interviews that can be more easily analyzed
and compared.
• Closed, fixed-response interview - where all interviewees are asked the
same questions and asked to choose answers from among the same set
of alternatives. This format is useful for those not practiced in
interviewing.

24. Types of Topics in Questions
Patton notes six kinds of questions. One can ask
questions about:
• Behaviors - about what a person has done or is doing
• Opinions/values - about what a person thinks about a topic
• Feelings - note that respondents sometimes respond with "I
think ..." so be careful to note that you're looking for feelings
• Knowledge - to get facts about a topic
• Sensory - about what people have seen, touched, heard,
tasted or smelled
• Background/demographics - standard background questions,
such as age, education, etc.
Note that the above questions can be asked in terms of past,
present or future.

25. Sequence of Questions
• Before asking about controversial matters (such as
feelings and conclusions), first ask about some
facts. With this approach, respondents can more easily
engage in the interview before warming up to more
personal matters.
• Intersperse fact-based questions throughout the
interview to avoid long lists of fact-based questions, which
tends to leave respondents disengaged.
• Ask questions about the present before questions about
the past or future. It's usually easier for them to talk
about the present and then work into the past or future.
• The last questions might be to allow respondents to
provide any other information they prefer to add and
their impressions of the interview.

26. Wording of Questions
• Wording should be open-ended. Respondents should be
able to choose their own terms when answering questions.
• Questions should be as neutral as possible. Avoid wording
that might influence answers, e.g., evocative, judgmental
wording.
• Questions should be asked one at a time.
• Questions should be worded clearly. This includes
knowing any terms particular to the program or the
respondents' culture.
• Be careful asking "why" questions. This type of question
infers a cause-effect relationship that may not truly exist.
These questions may also cause respondents to feel
defensive, e.g., that they have to justify their response,
which may inhibit their responses to this and future
questions.

27. Conducting Interview
• Occasionally verify the tape recorder (if used) is working.
• Ask one question at a time.
• Attempt to remain as neutral as possible. That is, don't show strong
emotional reactions to their responses. Patton suggests to act as if
"you've heard it all before."
• Encourage responses with occasional nods of the head, "uh huh"s, etc.
• Be careful about the appearance when note taking. That is, if you jump
to take a note, it may appear as if you're surprised or very pleased about
an answer, which may influence answers to future questions.
• Provide transition between major topics, e.g., "we've been talking
about (some topic) and now I'd like to move on to (another topic)."
• Don't lose control of the interview. This can occur when respondents
stray to another topic, take so long to answer a question that times
begins to run out, or even begin asking questions to the interviewer.

28. Immediately After Interview
• Verify if the tape recorder, if used, worked
throughout the interview.
• Make any notes on your written notes, e.g., to
clarify any scratchings, ensure pages are
numbered, fill out any notes that don't make
senses, etc.
• Write down any observations made during the
interview. For example, where did the interview
occur and when, was the respondent particularly
nervous at any time? Were there any surprises
during the interview? Did the tape recorder
break? Dr. Chandana Kasturiarachchi-

29. Preparation for Interview
• Choose a setting with little distraction. Avoid loud lights or
noises, ensure the interviewee is comfortable (you might
ask them if they are), etc. Often, they may feel more
comfortable at their own places of work or homes.
• Explain the purpose of the interview.
• Address terms of confidentiality. Note any terms of
confidentiality. (Be careful here. Rarely can you absolutely
promise anything. Courts may get access to information, in
certain circumstances.) Explain who will get access to their
answers and how their answers will be analyzed. If their
comments are to be used as quotes, get their written
permission to do so. See getting informed consent.

30. Preparation for Interview
• Explain the format of the interview. Explain the type of
interview you are conducting and its nature. If you want
them to ask questions, specify if they're to do so as they
have them or wait until the end of the interview.
• Indicate how long the interview usually takes.
• Tell them how to get in touch with you later if they want
to.
• Ask them if they have any questions before you both get
started with the interview.
• Don't count on your memory to recall their answers. Ask
for permission to record the interview or bring along
someone to take notes.

32. TIPS FOR EFFECTIVE RESEARCH
INTERVIEWS
• Make sure the research question is clear.
• Develop a check list of the questions to be
asked during the interview.
• Express clearly the purpose of the interview.
• Start with a neutral question to facilitate free
flow of information.
• Use open-ended questions so that the
respondent can choose his answer.
Dr. Chandana Kasturiarachchi-
chacmb@gmail.com
32

33. TIPS FOR EFFECTIVE RESEARCH
INTERVIEWS
• Limit the content of each question with a
single idea to avoid confusion.
• Reduce questions that give responses of `yes'
or `no', because they give limited information.
• Do not influence the respondent by asking
leading questions.
• If you have not understood the response ask
the respondent to repeat and clarify.
• Do not assume answers.
Dr. Chandana Kasturiarachchi-

33

34. TIPS FOR EFFECTIVE RESEARCH
INTERVIEWS
• Do not pass judgments.
• Avoid irrelevant discussions.
• When you change the tack, inform the
respondent that you are doing so.
• Keep the interview short.
• At the end of the interview summarize the
points reported and ask the respondent if the
summary is correct.
