The In Depth Interview Method

This paper aims to provide the best practice to implement effectively one of the most common methods of data collection: the in depth interview. Having already discussed the diversity of research methods to collect data, given the nature and insights of the in depth interview in the previous part (In depth interview: An important method of qualitative data collection), this guideline focuses on evolving a practical consideration in preparing, implementing and applying the in depth interview method.

 Establish the personal contact
 Regard the ethical issues through the seven-stage of interviewing

...of the validity, reliability, generalisability and the improvement of the data quality are always necessary when interviewing. It is suggested to make a good preparation to overcome the issues affecting the data quality. (For more details, see Section: Necessary Actions to Have a Good Preparation for the Interview Process).
• Time consuming: It can take a lot of time to go through the process of interviewing. See the Section of “A Consideration of the Time Frames” to manage a good time line of conducting the data collection by the in depth interview.
• Participants versus Interviewers: Participants can cause difficulty in the interview (such as giving a long answer, changing their emotions, interviewing the interviewer, having memory problems). The interviewer must be trained adequately to be able to use the interview techniques in dealing with intricate situations.
