Mixed method design is often noted as a methodology capitalizing on the advantage of in-depth study in qualitative approaches and the power of generalization in quantitative approaches.
To be useful, acknowledging the fundamental assumption underpinning these two approaches is paramount. Qualitative approach is individualistic where the findings are rich in explaining a phenomenon of interest in context while quantitative approach is normative where the findings represent an average pattern of a phenomenon of interest in a population.

2. Mixed methods: what it is?
“mixed methods research is the type of
research in which a researcher or team of
researchers combines elements of qualitative
and quantitative research approaches for the
broad purpose of breadth and depth of
understanding and corroboration”
Jonson, Onwuegbuzie and Turner, 2007
3. Current uses (purpose) of
mixed methods
• Triangulation (tap on the strength of each
method)
• Provides a better understanding
• Exploratory concept
• Explanatory concept
understanding human phenomena
Creswell, 2009
Webb et al 1996
Plano Clark, Creswell, 2007
4. The beginning of mixed methods
• Evolves from a single study using multi-trait or
multi-method research – 1959 by Campbell &
Fiske
• Started off as mixing of methods
– Later, the debates focus on the validity of findings,
missing philosophical underpinning
interpretation of findings
(sense making)
5. The debate on mixed methods
It is about researchers’ worldview
The 2 contradicting worldviews are incompatible and
incommensurable.
Trapped in these two paradigm (Symonds, 2008)
Quantitative Qualitative
Objective reality that is observable
and discoverable
Multiple reality as constructed by
society
Post-positivist Constructivist
Objective Interpretive
Distancing researchers from
researched
Researchers actively contribute to
data, analysis, results and
interpretation
6. Further development to
reconcile the debate
• Need to have philosophical assumptions that
guide the direction of data collection and
analysis(Bryman, 1984; Sale, 2002; Creswell and clark 2007; Biesta, 2010)
– Guide researcher on what is researchable
– Anchor the interpretation of results
7. Pragmatism
• Pragmatism: American philosophy
• Focus on the purpose of the research and its
practicality (Tashakkori & Teddlie, 1998; Nastasi & Hitchcock & Brown, 2010;
Biesta, 2010)
8. Pragmatism
Knowledge
• is regarded both as constructed and as a function of a
people environment interaction
• is meaningful if there is a practical consequence to it
(Biesta, 2010; Greene, 2010)
The practicality was not highlighted in the traditional
debates about
ontology and epistemology
(positivist vs constructivist)
9. Purpose & Assumptions
Purpose of the
study
Lived-experience
Social processes –
theory building
Representativeness
in a population
Methods (comes with
assumptions)
Phenomenology
GTM
Quantitative
It is from the assumptions that we draw and
limit our inferences – avoiding over claiming
10. The fundamental assumptions
• qualitative approach is individualistic where the
findings are rich in explaining a phenomenon of
interest in an individual context
purpose: to infer the findings to the understanding of an
individual (or a phenomenon)
• quantitative approach is normative where the
findings represent an average pattern of a
phenomenon of interest in a population
purpose: to infer the findings to a population
11. This presentation:
• To demonstrate logic reconciliation of study
findings from two methods with different
assumptions with an example

• Many of the illness can be treated or prevented
• Primary care doctors have a role of engaging male
patients into health care
14. Objectives (purpose) of the study
To develop an explanatory model of the process of how
primary care doctors (PCDs) make the decision to undertake
men’s health check-ups in Malaysia
1. First, it aims to identify the determinants and process of
individual doctors’ decision making.
2. Second, to quantify the average impact of each determinant,
and rank its average significance on the decision-making
processes among Malaysian PCDs.

25. Issues in comparing
the two results
• Why is there a discrepancy?
– Which are the important determinants?
– Which one do we trust?
– Which is more valid?
The answer:
Which perspective are we coming from?
26. The fundamental assumptions
• qualitative approach is individualistic where the
findings are rich in explaining a phenomenon of
interest in an individual context
purpose: to infer the findings to the understanding of an
individual (or a phenomenon)
• quantitative approach is normative where the
findings represent an average pattern of a
phenomenon of interest in a population
purpose: to infer the findings to a population
A revisit to slide 10
27. The relevance of qualitative
findings: understanding a doctor
My main concern is what
would men think about me if
I am to engage them in
health check
I am worry that I am not
competent enough to offer
men’s health check
28. The relevance of quantitative
findings: understanding Malaysian PCDs
Most would think perception of receptivity to discuss men’s health
determines their decision to engage them with health checks
29. Combining the two
• They simply explain two different phenomena
• Helping a doctor: understand him/her as an
individual PCD
• Helping to draft a policy/group interventions:
understand what most PCDs think
30. Practicality of mixed methods
Most people
are unhappy
about seeing
doctors, but
what about
you?
Applying an understanding about an
average to an individual
31. Conclusion
• Mixed methods: what is the purpose and
phenomena of interest.
• Assumptions must be acknowledged
• Appropriate inference depends on the rigor of
methodology and interpretation of findings
• Correct inference leads to appropriate
practical solution
