Abstract：
OBJECTIVE: Gay and bisexual men are at an increased risk for eating disorders (EDs) and muscle dysmorphia (MD) compared with their heterosexual counterparts. Existing dissonance-based (DB) EDs prevention programs for this population have been evaluated in the United States; however, these programs have not been evaluated in the Brazilian context. Thus, we investigated the feasibility, acceptability, and efficacy of a DB ED prevention program (i.e., the PRIDE Body Project) among Brazilian cisgender gay and bisexual men.
METHODS: Eligible men were randomly assigned to either a DB intervention (n = 74) condition or an assessment-only control (AOC) condition (n = 75). Participants completed measures assessing ED and MD risk and protective factors at baseline, post-intervention, 1-month, 6-month, and 1-year follow-up. Those in the intervention condition also completed acceptability measures.
RESULTS: Feasibility and acceptability ratings were highly favorable. Regarding efficacy, post-intervention results were not significant, except for self-objectification, which showed a significantly greater decrease in the DB condition compared with the AOC condition at all time-points of follow-ups (Cohen\'s d = -0.31 to -0.76). At follow-up, the DB condition showed significantly greater decreases in appearance-ideal internalization, drive for muscularity, self-objectification, ED and MD symptoms at 1-month, 6-month, and 1-year follow-ups (d = -0.33 to -0.92) compared with the AOC condition. Significant increases were observed in the DB compared with the AOC condition for body appreciation at 1-month, 6-month, and 1-year follow-ups (d = 0.31-0.81).
CONCLUSIONS: Results support the feasibility, acceptability, and efficacy of the PRIDE Body Project up to 1-year in Brazilian cisgender gay and bisexual men.

摘要：
目的：与异性恋者相比，男同性恋者和双性恋者患进食障碍（ED）和肌肉畸形（MD）的风险增加。在美国，已经评估了针对该人群的现有基于不和谐的（DB）ED预防计划；但是，这些项目尚未在巴西的背景下进行评估。因此，我们调查了可行性，可接受性,和DBED预防计划的有效性(即，PRIDEBody项目）在巴西顺性同性恋和双性恋男性中。
方法：符合条件的男性被随机分配到DB干预（n=74）或只评估对照（AOC）条件（n=75）。参与者在基线时完成了评估ED和MD风险和保护因素的措施，干预后,1个月,6个月,和1年随访。处于干预状态的人也完成了可接受性措施。
结果：可行性和可接受性评级非常好。关于功效，干预后结果不显著，除了自我客观化，在所有随访时间点，与AOC条件相比，DB条件的下降幅度明显更大（Cohen'sd=-0.31至-0.76）。在后续行动中,DB条件显示外观理想内化的下降幅度明显更大，驱动肌肉发达，自我客观化,1个月时的ED和MD症状，6个月,与AOC条件相比，随访1年（d=-0.33至-0.92）。与1个月时身体升值的AOC条件相比，DB中观察到显着增加，6个月,和1年随访（d=0.31-0.81）。
结论：结果支持可行性，可接受性,PRIDE身体项目在巴西顺性同性恋和双性恋男性中的效力长达1年。
