Studies of the Tripartite Influence Model conducted with female samples suggest that thinness-oriented pressures, internalization, and appearance comparisons may be risk factors for disordered eating. However, limited work has investigated this model among men utilizing measures specifically designed to assess both muscularity- and thinness-oriented processes, which characterize male body image concerns. To address this gap, the current study examined the Tripartite Influence Model of disordered eating among men using a battery of such measures. A convenience sample of 265 male undergraduates completed validated, self-report measures of disordered eating, muscularity- and thinness-oriented appearance pressures, internalization, and appearance comparisons. Path analyses supported a slightly modified version of the Tripartite Influence Model, indicating direct and indirect paths from sociocultural pressures to disordered eating via internalization and appearance comparisons. These results provide support for a version of the Tripartite Influence Model among men. Specifically, muscularity- and thinness-oriented pressures appear to be related to disordered eating among college men via indirect pathways involving thin internalization, muscular internalization, and appearance comparisons. Future work is needed, however, to examine whether the model would generalize to muscularity-oriented disordered eating.
对女性样本进行的三方影响模型研究表明，追求消瘦的压力、内化和外貌比较可能是饮食失调的风险因素。然而，利用专门设计的评估肌肉和消瘦过程的测量方法来研究男性的这一模型的工作有限，这些过程是男性身体形象关注的特征。为了解决这一差距，本研究使用了一系列此类测量方法，在男性中检验了饮食失调的三方影响模型。一个由 265 名男性本科生组成的方便样本完成了经过验证的、自我报告的饮食失调、肌肉和消瘦导向的外貌压力、内化和外貌比较的测量。路径分析支持三方影响模型的一个略有修改的版本，表明社会文化压力通过内化和外貌比较对饮食失调有直接和间接的影响。这些结果为男性三方影响模型提供了支持。具体来说，肌肉和消瘦导向的压力似乎通过涉及消瘦内化、肌肉内化和外貌比较的间接途径与大学生的饮食失调有关。然而，未来需要进一步的研究来检验该模型是否适用于以肌肉为导向的饮食失调。
