What this study is
The goal of this controlled trial is to learn whether a brief single-session intervention (SSI) can reduce binge eating symptoms by targeting overvaluation of weight/shape in women with recurrent binge eating.
The main questions it aims to answer are:
- Does assessment alone reduce binge eating severity and overvaluation of weight/shape compared to a control group undergoing minimal assessment?
- Does adding a values-based reflection and goal-setting component (the full SHAPE intervention) add benefits beyond the assessment alone?
Researchers will compare three groups:
1. assessment-only, 2. full SHAPE intervention, and 3. minimal assessment control to see if both active conditions outperform the control, and whether the full intervention adds any benefits beyond the assessment itself
Participants will:
- Complete a semi-structured eating disorder assessment (Eating Disorder Examination)
- Depending on assignment, also complete a values-based reflection and goal-setting exercise with psychoeducation
- Complete follow-up assessments evaluating binge eating severity, overvaluation of weight/shape, clinical impairment, binge frequency, and related outcomes.
