Abstract:
The tripartite model of influence proposes that three primary core sources of influence-parents, peers and media-contribute to the development of body dissatisfaction and disordered eating. In the current study, this model was examined in a sample of 205 undergraduate women. This study added to previous research by investigating mother and father criticism separately and by examining the potential moderating effects of parental attachment in the pathway to body dissatisfaction. Results indicated partial support for the tripartite model of influence. Sociocultural influences (media) were found to be a significant predictor of body dissatisfaction, but not parental or peer criticism. Anxious attachment was found to be a significant moderator on the effects of sociocultural attitudes in body dissatisfaction. Limitations and future research implications are discussed.
