Body image issues associated with eating disorders involve attitudinal and perceptual components: individuals' dissatisfaction with body shape or weight, and inability to assess body size correctly. While prior research has mainly explored social pressures produced by the media, fashion, and advertising industries, this paper focuses on the effects of personal networks on body image, particularly in the context of internet communities. We use data collected on a sample of participants to websites on eating disorders, and map their personal networks. We specify and estimate a model for the joint distribution of attitudinal and perceptual components of body image as a function of network-related characteristics and attributional factors. Supported by information gathered through in-depth interviews, the empirical estimates provide evidence that personal networks can be conducive to positive body image development, and that the influence of personal networks varies significantly by body size. We situate our discussion in current debates about the effects of computer-mediated and face-to-face communication networks on eating disorders and related behaviors.
个体对身体形状或体重的不满，以及无法正确评估身体大小的能力。虽然之前的研究主要探讨了媒体、时尚和广告行业产生的社会压力，但本文侧重于个人网络对身体意象的影响，特别是在互联网社区的背景下。我们使用在饮食失调网站上收集的参与者样本数据来绘制他们的个人网络。我们指定并估计了一个模型，用于将身体意象的态度和感知成分的联合分布作为网络相关特征和归因因素的函数。通过深入访谈收集的信息提供了证据，证明个人网络有助于积极的身体意象发展，并且个人网络的影响因体型而异。我们将讨论置于当前关于计算机中介和面对面交流网络对饮食失调和相关行为影响的辩论中。
