About this study
Official title: Testing a Single-session Consultation for Reducing Binge Eating
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:
Read more
- 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:
- assessment-only,
- full SHAPE intervention, and
- 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.
- Conditions
- Binge Eating, Binge Eating Behaviour, Binge Eating/Loss of Control Eating, Body Image, Body Image Disturbance
- Being tested
- Assessment-only, values-based reflection and goal-setting/action-planning exercises, Minimal-Assessment Control
- Keywords
- single session, single-session consultation, single-session intervention, binge eating, disordered eating, binge-spectrum disorder, body image, body image concerns, weight/shape concerns, overvaluation, loss of control eating
- Medical subject headings
