1 Pamina M. Gorbach, MHS, DrPH University of California, Los Angeles (UCLA) Using Qualitative Methods in STD/HIV Behavioral Research

2 What is qualitative research? "Qualitative" research is the study of the words and the meaning behind behaviors. Seeks to answer "WHY" people practice certain behaviors Collects words for data.

3 What is quantitative research? ”Quantitative" research is the study of numbers. Asks "how many" people practice "how many" different behaviors. Main tool is the survey. The aim is to find numerical patterns in responses to survey questionnaires or observed behaviors. Indicates magnitude of people's decisions and behaviors.

4 Uses of Qualitative methods QUALITATIVEQUANTITATIVE RESULTS Model 1 Steckler et al. 1992 1. A tool to generate ideas. 2. A preliminary step in developing a quantitative study.

5 Uses of Qualitative methods QUALITATIVE QUANTITATIVE RESULTS Model 2 Steckler et al. 1992 3. To help understand the results of a quantitative study.

6 Uses of Qualitative methods QUALITATIVE QUANTITATIVE RESULTS Model 3 Steckler et al. 1992 4. The primary data collection method – sometimes but not necessarily along with a quantitative study like a survey

7 Main Data Collection Methods In-depth individual interviews In-depth individual interviews Focus groups Focus groups Participant observation Participant observation Pile sorting Pile sorting

8 Individual Interviews AKA Ethnographic interview = open-ended, in-depth interview with one individual. Probes; collects respondent’s perspective and words; follows guide; level of structure varies. WHEN??? Complex subject matter and knowledgeable respondents Highly sensitive subject matter Geographically dispersed respondents Peer pressure an issue - social desirability a threat

9 Individual Interviews ADVANTAGES: Most in-depth. Why behaviors are practiced. Most in-depth. Why behaviors are practiced. Data on how people think and talk; conceptualizations of behavior. Data on how people think and talk; conceptualizations of behavior. Exact words people & language use amongst themselves. Exact words people & language use amongst themselves. “Emic” perspective = insider’s perspective. “Emic” perspective = insider’s perspective.DISADVANTAGES: Based on a few people, usually not systematic sample, but purposeful or convenience sample. Based on a few people, usually not systematic sample, but purposeful or convenience sample. Not generalizable. Not generalizable. Interviews very long, lots of data! Time consuming to analyze.

10 Focus Groups Open-ended group interviews that promote discussions between participants on specific topics. Usually 6-8 individuals matched by age, gender or ethnicity. WHEN? Group interaction important Cost and timing issues Idea generation Problem identification and definition goal Evaluating messages for an intervention

11 Focus Groups ADVANTAGES: Some people more comfortable and talk more openly in group settings. Natural way some people talk about problems and personal issues in some cultures. Some people more comfortable and talk more openly in group settings. Natural way some people talk about problems and personal issues in some cultures. Collects information on social norms. Collects information on social norms. DISADVANTAGES Difficult to access practice of very personal or sensitive behaviors in groups - may only learn about behavior people will admit in front of others. Difficult to access practice of very personal or sensitive behaviors in groups - may only learn about behavior people will admit in front of others. Not GENERALIZABLE Not GENERALIZABLE Transcribing time consuming - often 30-40 pages each! Difficult to identify speakers. analytic challenge! Transcribing time consuming - often 30-40 pages each! Difficult to identify speakers. analytic challenge!

12 Participant Observation The researcher becomes participant in social event or group under study and records observations. Tell or not tell group being studied that it’s a study?? Advantages: Data is very deep and detailed. Disadvantages: Difficult to systematically collect; especially in middle of important moment - hard to take notes so details may be forgotten. Analytic methods for observation notes not well described.

13 Guidelines for Qualitative Data Collection Don’t let interviewer/ facilitator dominate Don’t let interviewer/ facilitator dominate Control interviews/ FGD Control interviews/ FGD Avoid questions TOO open – burden on respondent Avoid questions TOO open – burden on respondent LISTEN!!! Ask followup questions LISTEN!!! Ask followup questions Record so have direct quotations Record so have direct quotations Use probes – start with neutral ones like pauses & repetition Use probes – start with neutral ones like pauses & repetition

17 ANALYTIC APPROACH CASE: focuses on each person or each unit. When variation in individuals primary focus of the study. Use all the data from each person. Cross-Case: Groups together answers from different people to common questions; analyze different perspectives on central issues. BOTH: Start with case descriptions then describe variations in answers to common questions.

18 How will Theory be Used? Apply existing? Apply existing? Develop grounded? Develop grounded?

19 Content or Theme Analysis WHAT: The identification of common themes and exploration of differences in how these themes are expressed and applied in a particular cultural context. HOW: Careful review of written transcripts noting specific words used by respondents to understand their systems of meaning. Spradley; 1979

20 CODE: an abbreviation or symbol used to classify words in the text by categories. CODING: process to identify categories of meaning. CODING TEXT Miles and Huberman; 1984

21 DESCRIPTIVE: Summarizes, describes, or defines. e.g., CONCEPTUAL: Addresses the deeper meeting or concept behind something e.g., TYPES OF CODES

22 Coded Text

23 Coding Strategies Individual – review and code alone Individual – review and code alone Consensual – review and code transcripts “together” and come to a consensus regarding codes in dispute Consensual – review and code transcripts “together” and come to a consensus regarding codes in dispute Separate – two or more researchers code text separately then compare Separate – two or more researchers code text separately then compare

24 Making a Matrix or Display Once the data are coded, develop a matrix that displays identified categories by groups of respondents. Enter short quotes or summarizing remarks from coded text into appropriate boxes in the matrix by category following a precise set of decision rules and criteria.

25 Making a Display Gorbach, PM et al 1997

26 More Displays Gorbach, PM et al 1997

27 Partnership Type by Group And More Displays!

28 Themes Underlying constructs that emerge from the codes and patterns observed in the data and/or were predetermined by the researcher and are later verified by the data Underlying constructs that emerge from the codes and patterns observed in the data and/or were predetermined by the researcher and are later verified by the data

29 Themes From Display: “Emerge” (1) Look for patterns (2) Build a logical chain of evidence (3) Make contrasts and comparisons (4) Cluster (5) Count - carefully

30 VERIFYING THEMES (1) Follow up on surprises (2) Triangulate - > other interviews, surveys (3) Make some if-then tests (4) Check out rival explanations (5) FEEDBACK - from informants, experts, colleagues, friends!

31 Presenting Themes

32 A Continuum of Disclosure Factors that influence HIV disclosure for MSM who disclose at different rates Disclosure much less likely Disclosure much more likely Sometimes Disclosure Nobody’s Business Denial Undetectable VL Just Sex Shared Responsibility Rejection Drugs Public Place More than “Just Sex” I am responsible Private Place Knew his Status He asked me Jail

33 Reasons to Not Notify: Hetero Men and Women Reasons to Not Notify: Hetero Men and Women Fear of gossip “I’m not going to tell noone because then it would be embarrassing on me - they would tell everybody else and I don’t want to be know as having no STDs.” 19 year old African American Male - GC “No, I figured they would go tell. That would be the talk of Seattle for me.” 15 year old African American Woman - CT Using Quotes: In Text

34 Feelings Regarding Sex: Women Who Test Positve for HPV Doesn’t want to have sex “Oh yeah, it did. Right now, like I said, I don't want to really meet no guys, I mean, I could meet them, talk to them, but as further as having sex, no.” L2: 21/L/new/STD Scared/concerned to infect partners “Yeah I felt depressed, I'm like damn, can't have sexual, I'm scared to have sex with somebody, cause I'm scared I might give it to him…” A9: 21/AA/middle/STD Feel more vulnerable can acquire something else “ I'm really not messing around, you know, that much no more, I don't, cause I don't, I just don't like the fact that, you know, like, somebody coulda, gave me something, or something like that, you know, and the act like, cool, they act like they don't have nothing, probably because they didn't' go and check ” A5: 22/A/middle/STD

35 Shared Responsibility Sometimes Disclosure “It’s a 50-50 street…they should ask as well as I should tell.” (30/W/SEA) “We have responsibility in the sense that, yes, we should tell them…but they have the responsibility to ask. It’s a 50-50 thing. It just depends on who initiates it.” (35/AA/LA) “I am usually expecting someone else to say something, and if they don’t, I assume that they are positive or that it does not make any difference to him.” (52/W/SEA)

36 Text in Manuscripts From: Gorbach PM, Galea J, Amani B, Shin A, Celum C, Kerndt P, Golden M. Don’t ask, Don’t Tell: Patterns of HIV Disclosure Among HIV Positive Men Who Have Sex with Men (MSM) with Recent STI Practicing High Risk Behavior In Los Angeles and Seattle. Sexually Transmitted Infections, 2004 December, 80(6):512-517.

38 Data Analysis: Review of Steps Data Analysis: Review of Steps 1. Collect data (conduct interviews/focus groups) 2. Manage data - transcribe interviews 3. Choose theoretical approach: grounded or applied 4. Determine analytic approach - case or cross-case 5. Code transcripts 6. Create matrices, displays - data reduction 7. Conduct theme analysis - identify themes 8. Draw conclusions - present themes

39 Improving Qualitative Data Quality Data collection - consider strengths & weakness of indepth interviews vs focus groups (convenience, social desirability, efficiency) Data collection - consider strengths & weakness of indepth interviews vs focus groups (convenience, social desirability, efficiency) Sampling – can move beyond convenience or “purposive” toward more representative Sampling – can move beyond convenience or “purposive” toward more representative Analytic approach – use software for data management & text analysis, develop matrices during analysis, identify theme through content analysis, compare themes by sub-groups Analytic approach – use software for data management & text analysis, develop matrices during analysis, identify theme through content analysis, compare themes by sub-groups
