Outcome Measures

Primary Outcomes (2)

  • Binge Eating Frequency (Continuous)

    Binge eating will be assessed by interview and self-report and the primary outcome is frequency. Frequency will be defined continuously (analyzed dimensionally).

    Post-treatment (4 months)

  • Body Mass Index (Percent Weight Loss)

    BMI is calculated using measured height and weight. Percent weight loss, where negative values represent proportional weight loss, is calculated as the difference between weight at post-treatment and baseline weight, divided by baseline weight. By definition, all participants have 0% weight loss at baseline.

    Post-treatment (4 months)

Secondary Outcomes (1)

  • Number of Participants Meeting Response Criteria
