Interviews & Focus Groups: Definition
- Types of intensive, qualitative research which generate data through directed, social interaction
- interviews involve questioning an individual or group with expertise or experience regarding your subject
- focus groups involve fostering discussion among groups of people with expertise or experience regarding your subject
Interviews & Focus Groups: Uses
- Research intangibles
- Intangibles = beliefs, values, attitudes, articles of faith, motives, desires ot passions a.k.a. personal & cultural traits
- In-depth study of particular individual or group
- sample popular opinion with interviews
- sample popular opinion with Focus groups
- major assumption:
- individual or group is representative of entire population
- intangible qualities of individual or group are representative of entire population
- knowing something about individual or group tells us something about entire population
Interviews & Focus Groups: Advantages
- interview and Focus groups (primary data)
- Focus Groups vs. Interviews
- Cost -less expensive
- Reliability – Interpersonal vs. group communication
- Focus Groups vs. Survey/Observation
- Faster -fixed, brief time-span
- Cost – Little if no time spent on the field
- Access – Easier to recruit volunteers
- Focus Groups vs. Interviews
- interviews and Focus Groups
- Lack historical perspective, “snapshot”
- Define the research problem
- Review the literature
- Select research method
- Design your research program
Treatment of human subjects
- ethical considerations
- do not place your participants at any risk
- propriety and modesty
- treat your participants with dignity and respect
Sample Strategy
- Participants must be able to answer your research question for representative sample, you must know entire population
- Set sample guidelines in relation to your analytical categories (e.g. if religious faith is a category, ensure all faiths represented)
- Each analytical category requires its own stratum
- Once they strategy set, recruit participation until each quota is filled result will be a “stratified” random sample
Sample Size
- Size of focus groups
- 6-10 people is the optimum number
- Number of focus groups
- any number of distinct focus groups is possible
- simple exploration / test question = 1-3 groups
- main research methods > 3 groups
- considerations: size of entire population
- number of analytical categories
Setting
- Location of interview or focus group can affect quality of data collected
Establish an interpretice context
- specific sources and location used
- mode of interpretation
- as always, justify your research decisions
Draft an Interview Guide
- Interview Guide- Pre-determined list of issues and questions to be addressed during interview (resembles coding schedule for content analysis)
- identify categories first
- Remaining questions second
- Researchers nmust ote time permitted for each question (e.g. 30 sec? 15 min?)
Recruit Participants
- If using focus groups, use your sampling strategy
Collect data
- use your interview guide
Data preparation and analysis
- organize answer in most appropriate way
- can count responses, as in content analysis
- Can create time line, as in historical research
- Can group data into themes, as in policy research
- look for signposts and patterns
- explain the patterns
