Abstract
Self-monitoring combined with contingency contracting resulted in weight loss, modification of dysfunctional eating habits, and increased or sustained exercise rates for two obese, mentally retarded adolescent females with Prader-Willi syndrome. Contingency contracting between clients and their parents/caregivers was used to specify consequences for daily self-monitoring, reduced caloric intake, weight loss, and exercise. Punishment for food stealing was also employed. Results suggest that contingency contracting is an effective technique for producing long-term weight loss in obese mentally retarded adolescents. Further, these techniques offer an alternative to the clinician considering solely dietary restriction or surgical intervention.
