Why Qualitative Public Health?

‘Real science’ does not begin with numbers, quantification, and statistical analysis…
in medicine, scientists work with non-numerical data… qualitative data are by no means a weak form of data;
rather, they are a different form that requires different, complex, and systematic analysis.
““
Kuckartz and McWhertor (2014) Qualitative Text Analysis, p.2

Qualitative research is an inquiry process of understanding
based on distinct methodological traditions of inquiry that explore a social or human problem.
The researcher builds a complex, holistic picture, analyses words,
reports detailed views of informants, and conducts the study in a natural setting.
““

Uses of Qual. Research in Public Health
1. To study the social, cultural, economic, and political factors that influence health and disease
2. To examine interactions between stakeholders3. To capture the “whole person” in their lifeworld4. To explore how people and communities interpret
health and disease5. To explore unanticipated meanings and connections

“Key Elements” of Qual Health Research
1. Full literature review of background information2. Choose a conceptual framework3. Choose a sampling strategy4. Recruit participants ethically5. Collect data in focus groups or interviews6. Analyze data by immersion, coding, grouping, linking to theory7. Present; publish; give feedback to community

Sampling in Qualitative Health Research
Not a goal of representative or fully generalizable; instead, the goal is to interpret a particular context and apply results to that or similar contexts. 1. Deviant sampling (study the extremes)2. Maximum variation (most diverse views)3. Homogenous sampling (study characteristics in depth)4. Snowball sampling (hard to reach)

Tips for Ensuring Qualitative Rigor
1. Prolonged engagement (multiple visits or interviews)2. Method and analysis grounded in theory3. Extensive and diverse sample4. Multiple methods (interviews, observation, casual discussion)5. Triangulation across different sources, perspectives6. Negative case analysis; highlight what contradicts your theory7. Diverse interviewers, peer debriefing, and multiple coders8. Respondent validation (community reviews your findings and reports)9. Clear documentation and data trail of all methodological decisions

Five Methodological ApproachesPhenomenology: studies how humans make sense and meaningEthnography: develop nuanced picture of social system or cultureInstitutional Ethnography: explore relations between organizations and human experienceGrounded Theory: build up from the data to theoretical insightDiscourse Analysis: what people are doing/building with language

What to know about qualitative analysis with CAQDAS softwareHOW DO I ACTUALLY ANALYZE MY INTERVIEWS AND OBSERVATIONS?

Data type and data analysis are not the same!
Kuckartz and McWhertor (2014) Qualitative Text Analysis, p.3; table from Bernard & Ryan 2010
![Page 18: Qualitative Research Methods for Public Health](https://reader033.fdocuments.us/reader033/viewer/2022042907/5886f0bd1a28abba528b6a85/html5/thumbnails/18.jpg)
Qualitative Data Analysisa. Typically starts with individual cases and builds up to a
hypothesis or argument.b. But depends on whether qualitative study is exploratory,
descriptive, hypothesis-testing, or evaluative (Diekmann 2007)c. Often begins with a close reading, and moves on to building
themes, case studies, categories, or concepts, which are shared along with descriptions and evocative quotations.
d. Most useful to provide a “rich understanding” for practitioners or to develop ideas to be tested using representative sample.

Whether to use qualitative analysis software:
Reasons to use
• Build complex codes • Test relationships• Handle large data• Good for teams
Reasons not to use
• Cost• Learning curve• Simple or few
interviews

Questions to ask before using software:
* How many interviews, observations, photos, news clippings, or fieldnotes have I collected?
* How in depth does my analysis need to be? * Does my advisor recommend a certain method of coding? * Have I studied a given method of coding or analysis? * Is software likely to help with this method for this project? * Do you need software skills for the job market?
