Abstract
The tripartite influence model of body image and eating disturbance is a recent theoretical approach that includes a test of direct (peer, parental, and media factors) and mediational links (internalization of societal appearance standards, appearance comparison processes) as factors potentially leading to body dissatisfaction and eating disturbance. The theory was evaluated in the current study in a sample of 391 adolescent females. A structural equation model that evaluated the tripartite model replicated previous findings reported by Keery, van den Berg and Thompson (2004) [Keery, H., van den Berg, & Thompson, J. K. (2004). A test of the tripartite influence model of body image and eating disturbance in adolescent girls. Body Image: An International Journal of Research, 1, 237-251.]. Additionally, a second model extended these findings, suggesting that peer and media influences are more important than parental influences. The results are discussed in light of the need for prevention programs to incorporate formative influences and mediational processes in the construction of intervention strategies.
