   The interviewer The role of the interviewer is to help motivate participants to share their thoughts and feelings on the topic you are studying. He or she needs to be able to listen carefully, to know when to seek clarifying information, and to pay attention to non-verbal as well as verbal responses. Be interested: It is crucial that the interviewer is genuinely interested in both the subject matter and in the participants.

completed at the end of the interview. Items may include issues such as whether the
participant appeared comfortable or anxious, truthful or dishonest, sober or under the
influence of drugs, etc. This will help you make decisions later during the analysis phase
about the validity of a given interview, and can be invaluable especially if the data do
