IDI vs Group
Individual Interview Group InterviewResearch Objective• Explore life of individual in depth• Create case histories through repeated interviews over time• Test a survey
• Orient the researcher to a field of inquiry and the language of the field• Explore a range of attitudes, opinions, and behaviors• Observe a process of consensus and disagreement
Topic Concerns• Detailed individual experiences, choices, biographies• Sensitive issues that might provoke anxiety
• Issues of public interest or common concern• Issues where little is known or of a hypothetical nature
Participants• Time-pressed participants or those difficult to recruit (e.g., elite or high-status participants)•Participants with sufficient language skills (e.g., those older than seven)• Participants whose distinctions would inhibit participation
• Participants whose backgrounds are similar or not so dissimilar as to generate conflict or discomfort• Participants who can articulate their ideas• Participants who offer a range of positions on issues
