A successful behavioral weight-loss program for moderately-retarded teenagers

Area of Science:

• Behavioral psychology
• Obesity research
• Developmental disabilities

Background:

• Obesity is a significant health concern in young adults.
• Effective weight management strategies are needed for individuals with intellectual disabilities.
• Behavioral interventions show promise for weight reduction.

Purpose of the Study:

• To evaluate the efficacy of a behavioral weight-reduction program.
• To assess the usefulness of specific behavioral techniques for weight loss.
• To determine the long-term effectiveness of the intervention.

Main Methods:

• A 14-week behavioral treatment program was implemented.
• Techniques included external/self-reinforcement, stimulus control, self-monitoring, and energy expenditure.
• Subjects received live or video-taped instruction.
• A wait-list control group was used for comparison.

Main Results:

• Behavior-therapy subjects achieved significantly greater weight loss than the control group.
• No significant difference in weight loss was found between live and video-taped intervention groups.
• Weight loss was maintained during subsequent maintenance and follow-up periods.

Conclusions:

• Behavioral weight-reduction programs are effective for moderately-retarded young adults.
• Both live and video-taped delivery methods are viable for this population.
• The intervention promotes sustained weight management.
