Final answer:
The ideal focus group size is between six to ten participants, with a preference for the lower end for sensitive subjects such as interviewing illegal immigrants separated from their children.
Step-by-step explanation:
The recommended size of focus groups generally ranges between six to ten participants. This size is small enough to allow everyone the chance to speak and large enough to provide a diversity of perspectives. In the sensitive case of interviewing illegal immigrants who were separated from their children, it might be wise to aim at the lower end of this range to ensure a comfortable and safe environment that encourages open discussion. Ensuring the confidentiality and providing incentives, much like the bus passes and gift certificates mentioned in Mini-Case Study Six, could improve participation and the quality of data collected. Moderating in a neutral environment rather than one associated with the issues under discussion might yield more candid and varied responses.
When considering the format and size of focus groups, researchers should also reflect on the characteristics of their target population and the complexity of the issue, which may warrant smaller groups. This is particularly important given the sensitive nature of the subject matter and the potential vulnerabilities of the participants.
The recommended size for focus group interviews with illegal immigrants who were separated from their children would depend on several factors. Generally, focus groups should have between 6 and 12 participants to allow for a diverse range of perspectives while maintaining an intimate and interactive environment. However, in the case of conducting focus group interviews with a sensitive population like illegal immigrants who have experienced trauma, it may be more appropriate to have smaller groups of around 4 to 6 participants.
