Answer to Question 1
ANS: C
Facilitators should prepare themselves to be effective moderators of the discussion, but to not develop preconceived ideas about the topic as this may hinder their ability to hear the perspectives of the group members. Encouraging group members to stretch their thinking and to share their perspectives is the role of an effective facilitator. It is important to instruct group members at the outset of the meeting that all views are valid and helpful to the researcher in understanding the topic. Once rapport is established with the group, one of the facilitator's roles is to reflect on inconsistencies among the participants and in their own thinking to challenge ideas and increase group interaction.
Answer to Question 2
ANS: D
Involving 4 to 12 participants in a discussion that lasts 45 to 90 minutes is typical for focus groups. Four to 12 participants is considered an appropriate size for a focus group, although 3 1/2 hours is longer than the typical focus group runs. Three participants is smaller than the typical number of participants, and a half-hour is less time than is needed to generate a rich discussion of the phenomenon of interest. Involving more than 12 participants in a focus group may limit hearing the perspective of less vocal members of the group and can be unwieldy. In addition, 3 hours is longer than typical focus groups last.
