Qualitative Research Methods

When should I do interviews?

  • when looking at experiences, perceptions, constructions, in which your subjects are invested in the situation
  • can generate thick, rich data from a relatively small number of participants
  • advantages of being able to probe into above areas, without predetermining results (with exception of structured interview)

Types of interviews

  • structured -- both questions and answer categories are set in advance, commonly used in quantitative approaches
  • semi-structured -- interviewer follows guide of questions, but these can be adapted in the moment, with follow-up questions to trace emerging areas of interest
  • unstructured -- questions mostly driven by the participant’s context, with perhaps general topics to guide the interviewer

Drawbacks of interviews

  • might be difficult with sensitive issues, due to lack of anonymity and individual interaction. Some people may be more comfortable discussing certain topics in a group setting
  • time-consuming for the interviewer, to conduct, transcribe, and analyze
  • less breadth of content -- will likely be smaller sample size than other methods
  • may not empower participants -- they don’t have direct control over what you produce as result of interaction
  • limited access to actual experience -- relying upon participant’s ability to recall and articulate experience, and limited by interviewer’s structure of questions
  • only one perspective on particular event, doesn’t fully represent motivations or perceptions of other actors
