Differential effects of community involvement on eating disorder prevention outcomes in sexual minority men.

Prior research has been conflicted on whether gay community involvement serves as a risk or protective factor for body image and eating disorders (EDs) in sexual minority men (SMM), perhaps given that prior research has examined community involvement unidimensionally. The present study examined whether non-appearance-based ("social activism") and appearance-based ("going out/nightlife") community involvement differentially predicted ED prevention outcomes in SMM. SMM ( N  = 73) enrolled in a randomized controlled trial of an ED prevention program completed measures of community involvement, drive for muscularity, body dissatisfaction, and bulimic symptoms at pre-intervention, post-intervention, and 1-month follow-up. "Social activism" community involvement moderated intervention effects for drive for muscularity and body dissatisfaction scores, but not bulimic symptoms, such that those who placed higher importance on social activism demonstrated expected improvements, while those who placed lower importance on social activism did not exhibit expected improvements. "Going out/nightlife" community involvement did not moderate intervention outcomes; however, greater importance of going out/nightlife was associated with increased body dissatisfaction. Findings support that the impact of community involvement on body image and ED risk for SMM may be nuanced. Encouraging community involvement through activism could help enhance ED prevention efforts for SMM.
