Abstract:

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. Seven hundred seven (N = 707) males (Mage = 23.98 years, SD = 4.07), 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 (χ²(2790) = 10548.421; p = .0001; χ²/df = 3.78; CFI = .79; PCFI = .75; RMSEA = .064 [90% CI = .062-.065]). 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. Implications for future research and prevention programmes are discussed.
