Gay males have increased risk for eating disorders compared to heterosexual males, establishing a need to develop and empirically evaluate programs to reduce risk for this population. The present study investigated the acceptability and efficacy of a cognitive dissonance-based (DB) intervention (The PRIDE Body Project(©)) in reducing eating disorder risk factors among gay males in a university-based setting.
Eighty-seven gay males were randomized to either a 2-session DB intervention (n = 47) or a waitlist control condition (n = 40). Participants completed eating disorder risk factor assessments pre-intervention, post-intervention, and at 4-week follow-up, and those receiving the intervention completed post-treatment acceptability measures.
Acceptability ratings were highly favorable. Regarding efficacy, the DB condition was associated with significantly greater decreases in body dissatisfaction, drive for muscularity, self-objectification, partner-objectification, body-ideal internalization, dietary restraint, and bulimic symptoms compared to waitlist control from pre- to post-intervention. Improvements in the DB group were maintained at 4-week follow-up, with the exception of body-ideal internalization. Body-ideal internalization mediated treatment effects on bulimic symptoms.
Results support the acceptability and efficacy of The PRIDE Body Project(©) and provide support for theoretical models of eating pathology in gay men.
与异性恋男性相比,男同性恋者患饮食失调症的风险增加,因此需要开发并通过实证研究评估针对该人群降低风险的项目。本研究调查了基于认知失调的干预措施(PRIDE 身体项目(©))在减少基于大学的同性恋男性饮食失调风险因素方面的可接受性和疗效。
87 名男同性恋者被随机分为 2 节基于认知失调的干预组(n = 47)或候补名单对照组(n = 40)。参与者在干预前、干预后和 4 周随访时完成了饮食失调风险因素评估,接受干预的参与者在治疗后完成了可接受性测量。
可接受性评分非常高。关于疗效,与候补名单对照组相比,基于认知失调的条件与身体不满、肌肉发达驱力、自我客体化、伴侣客体化、身体理想化内化、饮食限制和暴食症状从干预前到干预后显著减少有关。在 4 周随访时,DB 组的改善得以维持,除了身体理想化内化。身体理想化内化介导了治疗对暴食症状的影响。
结果支持 PRIDE 身体项目(©)的可接受性和疗效,并为男同性恋者饮食失调的理论模型提供了支持。
