How is an In-Depth Interview conducted?
IDIs are normally carried out face to face, but occasionally can be done over the phone.A mix can be accomplished with the use of web cams, FaceTime, Skype or similar videoconferencing tools when both parties have them available.
A discussion guide is used to frame the conversation. Many questions are open-ended rather than yes/no or multiple choice format. Because an IDI can veer off in many directions, it is important to leave adequate time for tangential paths to be explored.
