Inclusive dissonance-based body image interventions for college students: Two randomized-controlled trials of the EVERYbody Project.

Objectives: Two randomized-controlled studies explored the feasibility, acceptability, and efficacy of the EVERYbody Project, a gender-inclusive, diversity-focused, dissonance-based body image intervention for college students.

Method: Trial 1 (N = 98; 80% female, 14% male, and 6% gender-expansive) piloted the two-session intervention delivered by an expert (faculty or staff) and peer cofacilitators compared to a waitlist control. Trial 2 (N = 141; 79% female, 15% male, and 6% gender-expansive) utilized peer leaders, comparing the EVERYbody Project to a video and expressive writing intervention. Around half of the participants in both trials self-identified in one or more specific marginalized identity category. Changes in eating disorder symptoms and risk factors were assessed through 1-month follow-up. Trial 1 also assessed the intervention's impact on students with marginalized identities through qualitative interviews.

Results: In Trial 1, the EVERYbody Project produced greater reductions in eating disorder symptoms, internalized appearance norms, body dissatisfaction, and negative affect compared to the waitlist control through 1-month follow-up, with medium effect sizes. The impact was similar in students with marginalized and majority identities, and qualitative interviews suggested specific positives of the intervention. In Trial 2, there were significant changes in two of four outcomes for participants in the EVERYbody Project compared to the video and expressive writing intervention, but overall, the intervention impact was modest.

Conclusions: The EVERYbody Project is a feasible and acceptable inclusive dissonance-based body image program. It appears to be beneficial when delivered via experts, but research is needed to establish whether the program can be delivered using peer leaders with greater impact.
