What is the typical group size in behavioral obesity treatment?

• A. 10-15
• B. 5-9
• C. 15-25
• D. 20-30

Answer: (A)

Group size in behavioral obesity treatment is chosen to balance peer support with the clinician’s ability to provide individual attention. A moderate-sized group, about ten to fifteen participants, offers enough diversity of experiences for useful modeling and motivation, while still allowing the facilitator to give personalized feedback, monitor progress, and manage the session effectively. If the group is too small, you miss out on the benefits of peer interaction and shared problem-solving. If it’s too large, it’s harder for everyone to participate, for members to receive individualized guidance, and for the group to stay cohesive. For these reasons, the typical format uses roughly ten to fifteen participants.
