Behavioral treatment of obesity with monetary contracting: two-year follow-up

Abstract

Reported is a 2-year follow-up of a behavioral weight reduction program for men using monetary contracts of varying size and group versus individual contingencies. Although initial weight losses were large, in the absence of an effective maintenance program weight losses at two years were modest, similar to those obtained with less effective initial weight loss procedures. Group contracts were significantly more effective in producing long term loss than individual contracts. Reported behaviors associated with weight loss at 2 years are presented.
