The Tripartite Influence Model posits that sociocultural influences mediated by internalization and social comparison are predictors of disordered eating and body change behaviours. This study aimed to test the Tripartite Influence Model among Brazilian male university students, which has not been tested yet. 707 undergraduate students of the five Brazilian regions, completed measures of sociocultural influences, internalization, social comparison, body and muscularity dissatisfaction, disordered eating and body change behaviours. Structural equation modelling analyses showed good model-fitting. Parental influence was related to internalization, while peer influence with social comparison. Media influences were related to both internalization and social comparison. Internalization and social comparison are mediating variables that are related to body dissatisfaction and muscularity dissatisfaction. Finally, muscularity dissatisfaction was associated with body change behaviours.
三方影响模型认为，社会文化影响通过内化和社会比较的中介作用是饮食失调和身体改变行为的预测因素。本研究旨在检验三方影响模型在巴西男大学生中的适用性，目前尚未对此进行测试。来自巴西五个地区的 707 名本科生完成了社会文化影响、内化、社会比较、身体和肌肉不满意、饮食失调和身体改变行为的测量。结构方程模型分析表明模型拟合良好。父母的影响与内化有关，而同伴的影响与社会比较有关。媒体的影响与内化和社会比较都有关。内化和社会比较是中介变量，与身体不满和肌肉不满意有关。最后，肌肉不满意与身体改变行为有关。
