“Not everything that can be counted counts. Not everything that counts can be counted.”
“Not everything that can be counted counts. Not everything that counts can be counted.” -William Bruce Cameron “Informal Sociology: A Casual Introduction to Sociological Thinking”
Learning Objectives By the end of this session, fellows will be able to: • Identify when qualitative methodology is appropriate for answering a research question • Understand qualitative research principles for data collection, analysis and dissemination • Understand the challenges associated with collecting and managing qualitative data
Overview • Concepts that underlie qualitative research • What is it? • How and why is it useful? • What’s its relationship to quantitative methods? • Qualitative methods • Study design • Data gathering • Analysis & dissemination
What is qualitative research? • The study of things in their natural setting, qualitative researchers attempt to make sense of or interpret phenomena in terms of the meanings people bring to them. • Denzin and Lincoln (1994)
Why qualitative research? • To understand participants’ perspectives and the meanings they construct • How participants “make sense of things” • To develop a “profound grasp of the obvious.” • To examine reasons • To discover what variables might be important, generate hypotheses or theory (Hurley RE.Qualitative research and the profound grasp of the obvious. Health Services Research,1999;34:1119-1136)
Qualitative and Quantitative Research: Different ways of seeking the truth Qualitative • Constructivist • Inductive Generate hypothesis • Subjective Emphasizes meaning/ interpretation • Contextual “thicker data” on relatively few cases Quantitative • Positivist • Deductive Test hypothesis • Objective Emphasize measurement • Generalized “thinner data” on a large number of cases
Qualitative and quantitative data provide complementary insights Mixed Qualitative Quantitative • Address different research questions • Provide different perspectives about the same question
Advantages and Disadvantages of Qualitative Research Limitations Strengths Provides deep insight Understand alternate viewpoints through subjective data Exploratory research and hypothesis generation Not reliant on pre-defined variables Generalizability Time consuming Methods not as well-known as quantitative study designs Expense
Qualitative research requires rigor • Asking appropriate research questions • Developing appropriate study designs • Conducting data acquisition activities that are justifiable, innovative, and ethical • Employing analyses that are trustworthy • Producing evidence that is relevant and useful

Defining a research question • What problem in the universe are you trying to understand? • What are the gaps in the literature? • How will your study contribute to the literature by addressing identified gaps?
Case Example • Problem in the universe • Many parents are refusing to vaccinate their children • Gaps in the literature • Existing research is quantitative and/or relies on hypothetical (not real-time) decision-making • How will your qualitative study contribute? • “…(it will) describe the full range of mothers' attitudes about vaccinating their children and the promoters and inhibitors of mothers' acceptance of vaccinations during the time when mothers are actively deciding whether to vaccinate their infants.”
Identifying the researcher(s) • Will there be one researcher or a research team? • What skills and perspectives are available? • Consider consulting external researchers
Sampling Strategies • Sampling strategies • Typical cases (average) • Extreme cases (outliers) • Maximum variation sampling (range) • Snowball (chain) sampling • Iterative • Move back and forth between sampling and analyzing data • Thematic saturation • No more emergent patterns in the data
Gaining IRB approval • Be explicit and specific about what qualitative research is, how and why it is appropriate • Describe the researcher(s) and their experience with qualitative inquiry • Protect subjects and their data • Protect non-subjects you encounter • Note strategies to mitigate any harm to participants

Data Collection Techniques 1-on-1 Interviewing Focus groups Observing Video-taping Studying documents Administering questionnaires (with questions that generate descriptions) Eliciting narrative writing Gathering diaries Collecting drawings
Observation preparatory work • Have a clear purpose of the observation • Make explicit any model or interpretive framework • Identify examples of what to include and what to exclude • Reflexivity: know your biases • Formatting: consider an observation guide
Open-ended observation notes http://josephmcgee.wordpress.com/tag/ethnographic/
1-on-1 Interviews • One-on-one interviews represent a conversational partnership • Purpose: to obtain information about the participant’s feelings, thoughts, beliefs and experiences • Ask what, how and why questions • Consider: variable interview formats Highly structured Informal, open-ended
Focus Groups • Interviewing small groups of people • Relatively quick and inexpensive way to obtain a lot of data • Purpose: to foster a dialogue that clarifies or expands the participants’ views on the topic of interest • Consider: impact of group dynamics
Data collection: Observation • Purpose: describe and understand social action • Ethnography: studying a culture • Close, prolonged observation • Observation shifts between breadth to depth • Focused Observation: • Brief periods of observation that focus on a particular event or activity • Observation check list Focused Observation Ethnography

Data Analysis • Grounded theory • Iterative “coding” • Identify emerging concepts and themes • Generate hypotheses • Content Analysis to analyze documents • Using word counts to describe material • Can be quantitative and/or qualitative
Organize data into codes then themes • Codes are meant to label pertinent data • In vivo codes use participant terms • “Sociological constructs” use researcher terms • Organize codes into categories • Build categories into themes, lessons learned, takeaways • This is a process of inductive reasoning
Example coding map Theme Selective Coding Selective Coding Concept A Concept B Axial Coding Open Coding Open Coding Indicator Indicator Indicator Indicator
Example: Vaccine refusal Trust Selective Coding Selective Coding Environmental Inhibitors Knowledge Axial Coding Open Coding Open Coding Bad experience with past vaccination Skepticism of others around them Doesn’t know effects of disease Believes disease is not around

Trustworthiness • Triangulation • Methods • Observer • Participants • Peer debriefing • Member checking • Audits • Detailed evidence
Demonstrating rigor in qualitative results • Credibility - confidence in the 'truth' of the findings • Transferability - showing that the findings have applicability in other contexts • Dependability - showing that the findings are consistent and could be repeated • Confirmability - a degree of neutrality or the extent to which the findings of a study are shaped by the respondents and not researcher bias, motivation, or interest.
Dissemination • Make the research question clear • Describe the sampling strategy • Describe the researcher(s)
Dissemination • Show the data • Use quotes wisely • Be brief • Demonstrate rigor to build trustworthiness • Note the limitations to your study • Conclude with how the findings add to the body of knowledge
Journals to be aware of • Qualitative Health Research • Sociology of Health & Illness • Anthropology & Medicine • Social Science & Medicine • Studies in Medical Anthropology
