DESCRIPTION (provided by applicant): This application is in response to PA: NIMH Small Grants Program (PA-03-039). Because of the increased prevalence of eating disorders and their chronic nature, theoretically examining their precipitating and perpetuating mechanisms are essential for establishing effective prevention and treatment programs. The most empirically supported theory for the acquisition and maintenance of eating disorders is the socio-cultural model, which identifies the mass media's portrayal of the culturally-ideal physique of a thin and lean physique for women and a lean and muscular physique for men as the impetus behind increases in eating disorder symptoms (e.g., increased body dissatisfaction, anger, anxiety, depression). The most significant source of data examining the media effects on eating disorder symptoms are laboratory experimental studies that expose participants to images of the ideal physique to determine their immediate impact on eating disorder symptoms. Because these studies have contradictory results and methods, a meta-analytic synthesis of this literature and its moderating mechanisms is required before the effects of the mass media's portrayal of the ideal physique on eating disorder symptoms are determined. The objective of this study will be to meta-analytically review the laboratory research examining the acute exposure to the media's portrayal of the ideal physique on eating disorder symptoms and the mechanisms that moderate this effect. This objective will aid in understanding the Surgeon General's Report on Mental Health conclusion that mental illness and related health problems must be understood in a social and cultural context, and it will provide important information for further research in this area and for developing effective media-literacy interventions.

描述（由申请人提供）：本申请是在回应PA：NIMH小额赠款计划（PA-03-039）。由于饮食失调的患病率增加及其慢性性质，从理论上研究其沉淀和永久化机制对于建立有效的预防和治疗方案至关重要。获得和维持饮食失调的最具经验支持的理论是社会文化模型，该模型将大众媒体对女性瘦而瘦的文化理想体格和男性瘦而肌肉发达的体格的描述确定为饮食失调症状增加背后的动力（例如，增加的身体不满、愤怒、焦虑、抑郁）。研究媒体对进食障碍症状影响的最重要的数据来源是实验室实验研究，这些研究将参与者暴露在理想体格的图像中，以确定其对进食障碍症状的直接影响。由于这些研究有矛盾的结果和方法，荟萃分析综合文献及其调节机制之前，需要确定大众媒体的理想体质的饮食失调症状的写照的影响。本研究的目的将是荟萃分析审查实验室研究，研究急性暴露于媒体对饮食失调症状的理想体质的描述以及缓和这种影响的机制。这一目标将有助于理解卫生部长关于精神健康的报告的结论，即必须在社会和文化背景下理解精神疾病和相关的健康问题，并将为这一领域的进一步研究和制定有效的媒体扫盲干预措施提供重要信息。
