Interviews

Source: Dave Davis and St. Michael's Hospital http://www.stmichaelshospital.com/pdf/research/kt/interviews.pdf

What:
A conversation with a purpose.
Purpose:
To gain an in-depth understanding of individuals' perspectives, practices, and experiences.

Advantages:

  • Obtain personal, detailed understanding of areas being studied.
  • Can be used in conjunction with other strategies, for example to assist in survey design or to help explain practice patterns.

Disadvantages:

  • Conducting interviews and analyzing data requires extensive time and effort.
  • Lack of anonymity may limit respondents' openness.
  • Limited to a smaller sampling number.
  • Data is based on self-report.

Interview Tips:

Interviews can be structured, unstructured, or semi-structured. Semi-structured interviews utilize a series of open-ended questions as a guide:

  • Identify purpose and suitable sampling strategy. Purposive sampling is the selection of people who have background/experience related to the purpose of the interview.
  • Develop and pilot test interview question guide: questions should be neutral, sensitive, and clear, begin with open-ended questions and end with closed-ended questions, questions should flow.
  • Prepare interviewee: explain purpose of interview and types of questions to be asked, obtain consent, discuss issues of confidentiality, choose appropriate time and setting (can be in-person or by telephone).
  • During interview: establish comfortable rapport, repeat purpose of interview, ask probing questions, demonstrate active listening, be non-judgmental, allow for interviewee to express his/her own ideas and meanings, ensure that have understood interviewee?s meanings, maintain focus.
  • Record interviews: write notes during or after interview and/or audiotape (request permission), which can then be transcribed.
  • Thank respondents and provide contact information in case they have further information.
  • Analyze data: maintain open-mind (be aware of preconceived notions), read data, take notes, code data, review for emerging themes.
