Effectiveness of peer-led dissonance-based eating disorder prevention groups: results from two randomized pilot trials.
Trial report in Behaviour research and therapy, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 27 papers, 2 of them syntheses that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThe present preliminary trials tested whether undergraduate peer leaders can effectively deliver a dissonance-based eating disorder prevention program, which could facilitate broad dissemination of this efficacious intervention.
methodIn Study 1, female undergraduates (N=171) were randomized to peer-led groups, clinician-led groups, or an educational brochure control condition. In Study 2, which improved a design limitation of Study 1 by using completely parallel outcome measures across conditions, female undergraduates (N=148) were randomized to either immediate peer-led groups or a waitlist control condition.
resultsIn Study 1, participants in peer- and clinician-led groups showed significantly greater pre-post reductions in risk factors and eating disorder symptoms than controls (M d=.64 and .98 respectively), though clinician- versus peer-led groups had higher attendance and competence ratings, and produced stronger effects at posttest (M d=.32) and at 1-year follow-up (M d=.26). In Study 2, participants in peer-led groups showed greater pre-post reductions in all outcomes than waitlist controls (M d=.75).
conclusionsResults provide novel evidence that dissonance-based eating disorder prevention groups led by undergraduate peers are feasible and produce greater reductions in eating disorder risk factors and symptoms than minimal-intervention control conditions, but indicate that effects are smaller for peer- versus clinician-led groups.
