    Summary

    Response-cost interventions, with or without reinforcement, effectively reduced weight in overweight girls. While some weight was regained post-treatment, the reinforcement group maintained a significant difference from controls.

    Area of Science:

    • Pediatric Obesity
    • Behavioral Health
    • Weight Management Interventions

    Background:

    • Childhood obesity is a significant public health concern.
    • Effective, evidence-based weight reduction strategies for children are crucial.
    • Parental involvement is a key factor in pediatric weight management.

    Purpose of the Study:

    • To evaluate the efficacy of two response-cost based weight reduction treatments in overweight girls.
    • To compare a response-cost plus reinforcement strategy with a response-cost only strategy.
    • To assess the long-term effects of these interventions.

    Main Methods:

    • Fifteen overweight girls (5-11 years) were randomized into three groups: response-cost plus reinforcement, response-cost only, and a no-treatment control.

  • Interventions involved weekly meetings with financial penalties for non-adherence and failure to meet weight-loss goals.
  • The reinforcement group included parental facilitation of reinforcement and stimulus control techniques.

    • Main Results:

    • Both response-cost groups achieved significantly greater weight loss than the control group after 12 weeks.
    • At an 8-week follow-up, the response-cost plus reinforcement group maintained significant weight loss, while the response-cost only group showed a trend.
    • A 31-week follow-up indicated no significant treatment effect but a trend towards slower weight gain in the reinforcement group.

    Conclusions:

    • Response-cost interventions are effective for pediatric weight reduction in the short term.
    • Parental reinforcement may enhance the long-term maintenance of weight loss in children.
    • Further research is needed to optimize sustained weight management strategies for childhood obesity.
