Abstract

The Tripartite Influence Model of body image and eating disturbance proposes that three formative influences (peer, parents, and media) affect body image and eating problems through two mediational mechanisms: internalization of the thin-ideal and appearance comparison processes. The current study evaluated this model in a sample of 325 sixth through eighth grade girls. Simple path analyses indicated that internalization and comparison fully mediated the relationship between parental influence and body dissatisfaction and partially mediated the relationship between peer influence and body dissatisfaction. Additionally, internalization and comparison partially mediated the relationship between media influence and body dissatisfaction. Six a priori SEM models based on the full Tripartite Influence Model were also evaluated. A resulting model was found to be an adequate fit to the data, supporting the viability of the Tripartite Model as a useful framework for understanding processes that may predispose young women to develop body image disturbances and eating dysfunction.

摘要

身体意象与饮食失调的三方影响模型提出，三种形成性影响因素（同伴、父母和媒体）通过两种中介机制影响身体意象和饮食问题：瘦理想的内化和外貌比较过程。本研究在325名六年级至八年级女孩的样本中对该模型进行了评估。简单路径分析表明，内化和比较完全中介了父母影响与身体不满之间的关系，部分中介了同伴影响与身体不满之间的关系。此外，内化和比较部分中介了媒体影响与身体不满之间的关系。还评估了基于完整三方影响模型的六个先验结构方程模型。结果发现一个模型与数据拟合良好，支持三方模型作为理解可能使年轻女性易患身体意象障碍和饮食功能障碍的过程的有用框架的可行性。
