College represents a unique vulnerability period for the development of body dissatisfaction (BD) and disordered eating among women. Research has suggested that these public health concerns may be at least partly explained by social comparison and objectification theories, two prominent social psychological theories. Humans engage in social comparisons with others in order to understand how and where they fit into the world. Objectification theory holds that the feminine body has been constructed as an object to be gazed upon; given this, females learn to view themselves from an observer's perspective and to treat themselves as objects to be looked at. This proposal will extend previous research by examining how these two theories fit into an elaborated version of Stice's (1994) socio-cultural model of disordered eating and by using an experience sampling/ecological momentary assessment (EMA) approach, which involves assessing participants multiple times per day in their natural environments. Specifically, this proposal will use novel methodology (i.e., EMA), test social comparison and objectification as factors that may explain the relation between thin ideal internalization and BD in the socio-cultural model of disordered eating, and utilize rigorous prospective analyses - doing these 3 things will fill important gaps in the literature. A sample of 200 college women will participate, which will include 2 self-report questionnaire sessions (at the start and end of an academic semester) and a 2-week EMA component (i.e., via their personal computers, participants will complete a short set of questions 3x/daily mid-semester). Constructs assessed will include: pressure for thinness, thin ideal internalization, social comparison, body surveillance (the indicator of objectification), BD, and disordered eating. Key hypotheses: 1) increases in momentary social comparison and body surveillance will be associated with subsequent increases in BD and disordered eating; 2) momentary instances of social comparison and body surveillance will mediate the relation between thin ideal internalization and BD; 3) a socio-cultural model incorporating social comparison and body surveillance will provide a better fit to the data than a model that does not incorporate these constructs. Multilevel and structural equation modeling will be utilized to test these hypotheses. Results may inform future prevention programs for college women by identifying relevant and mutable behaviors that impact BD/disordered eating.

大学代表了身体不满（BD）和女性饮食不足的独特脆弱时期。研究表明，这些公共卫生问题至少可以通过社会比较和客观化理论（两种著名的社会心理理论）来解释。人类与他人进行社会比较，以了解他们如何以及适合世界的地方。客观化理论认为，女性身体已被构造为要注视的对象。鉴于这一点，女性从观察者的角度学会看自己，并将自己视为要看的对象。该提案将通过研究这两种理论如何融入Stice（1994）的详细版本的社会文化饮食模型，并使用经验抽样/生态瞬时评估（EMA）方法来延长以前的研究，该模型涉及在自然环境中每天多次评估参与者。具体而言，该提案将使用新颖的方法（即EMA），测试社会比较和客观化作为可能解释无序饮食社会文化模型中薄薄的理想内在化与BD之间关系的因素，并利用严格的前瞻性分析 - 进行这3件事将填补文献中重要的空白。样本 200名大学妇女将参加，其中包括2个自我报告问卷调查会议（在学术学期的开头和结束时）和2周的EMA组件（即，通过其个人计算机，参与者将完成一组简短的问题3x/Daily每日学者）。评估的结构将包括：薄的压力，薄的理想内在化，社会比较，身体监视（客观化指标），BD和饮食无序。关键假设：1）瞬间社会比较和身体监视的增加将与随后的BD和饮食无序的饮食增加有关； 2）社会比较和身体监视的瞬间实例将调解理想内在化与BD之间的关系； 3）与不包含这些结构的模型相比，结合社会比较和身体监视的社会文化模型将为数据提供更好的拟合。多级和结构方程模型将用于检验这些假设。结果可以通过确定影响BD/无序饮食的相关和可变行为来为未来的大学妇女提供预防计划。
