Study summary

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.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • ≥ 18 years old
  • Identify as cisgender female
  • self-reported ≥ 18.5 kg/m²
  • Rate the extent to which their weight or shape influences how they feel about themselves as a "4" or higher on a 7-point Likert scale on screening measures
  • ≥1 binge eating episode every 2 weeks (i.e., ≥ six episodes over 3 months) at the time of screening

Exclusion criteria

Exclusion Criteria:

  • \< 18 years old
  • Assigned male at birth
  • Gender identity different from biological sex indicated on birth certificate
  • Purging behaviors (i.e., self-induced vomiting, laxative misuse, or diuretic misuse) ≥ 1x/week in the last 3 months at the time of screening.
  • Engaged in structured psychological therapy or counseling (defined as attending sessions > 1x/month in the past 3 months)
  • Prior participation in studies that include administration of the EDE interview at Ohio University (IRB-FY24-403, IRB-FY25-330, and IRB-21-F-14).
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Oct 2025; primary completion for Oct 2026, 12 months later.

Of 68 non-industry interventional studies with no phase under Bulimia, half reached primary completion within 26 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 52. This study's planned 12 months is below that.

Counting every sponsor, half of 70 studies reached it within 26 months; a quarter within 10 and three quarters within 52.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 20, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
