The type of research conducted by Mallory in the above question, can be termed as In-Depth Interviews.
A qualitative research technique known as "in-depth interviewing" involves conducting lengthy one-on-one interviews with a smallgroup of respondents to learn more about their viewpoints on a certain concept, plan, or circumstance.
The interview is not overly planned, but it does cover a few subjects based on a guide, allowing the interviewer to explore themes pertinent to the interviewee.
The interviewer examines the information generated by the interview during the interview.
In order to gain a deep grasp of attitudes, perspectives, motivations, etc., interviewers have a larger opportunity to ask follow-up questions, probe for more information, and circle back to critical questions later in the interview.
