Social body comparison and internalization: mediators of social influences on men's muscularity-oriented body dissatisfaction.

Research suggests that body dissatisfaction (BD) is prevalent among males and associated with unhealthy outcomes. Consistent with the well-validated Tripartite Influence Model, internalization of an ideal body figure and social body comparison have received support as predictors of men's dissatisfaction with their muscularity. However, empirical investigations with males that include both constructs are lacking. The current study examined the associations of both constructs with muscularity-oriented BD in a sample of college men (n=204). Results from hierarchical regression analyses revealed that internalization and social body comparisons had unique relations with men's muscularity-oriented BD. A structural equation model indicated that both constructs mediated the relationship between social influences and muscularity BD. Preliminary data on targets of male body comparisons also were presented. These findings provide evidence for extension of the Tripartite Influence Model to males, particularly when constructs are assessed in ways that are reliable and valid for this population.
