This study investigated whether an expanded tripartite influence model would represent gay men's experiences. This model was extended by adding partners and gay community involvement as sources of social influence and considering dual body image pathways (muscularity and body fat dissatisfaction) to muscularity enhancement and disordered eating behaviors. Latent variable structural equation modeling analyses upheld this model for 346 gay men. Dual body image pathways to body change behaviors were supported, although three unanticipated interrelationships emerged, suggesting that muscularity and body fat concerns and behaviors may be more integrated for gay men. Internalization of the mesomorphic ideal, appearance comparison, muscularity dissatisfaction, and body fat dissatisfaction were key mediators in the model. Of the sources of social influence, friend and media pressure to be lean, gay community involvement, and partner, friend, media, and family pressures to be muscular made incremental contributions. Unexpectedly, certain sources were directly connected to body change behaviors.
本研究旨在探讨扩大的三方影响模型是否能够代表男同性恋者的体验。该模型通过增加伴侣和同性恋社区的参与作为社会影响的来源，并考虑到双重身体形象途径（肌肉发达和身体脂肪不满）来增强肌肉发达和饮食失调行为，从而得到了扩展。潜在变量结构方程模型分析支持了该模型在 346 名男同性恋者中的应用。双重身体形象途径与身体变化行为之间存在关联，但出现了三个意外的相互关系，表明男同性恋者对肌肉发达和身体脂肪的关注和行为可能更加融合。中胚层理想的内化、外貌比较、肌肉发达不满和身体脂肪不满是该模型的关键中介因素。在社会影响的来源中，朋友和媒体对瘦的压力、同性恋社区的参与以及伴侣、朋友、媒体和家庭对肌肉发达的压力都做出了额外的贡献。出乎意料的是，某些来源与身体变化行为直接相关。
