Late Adolescent Body Dissatisfaction and Psychopathology

描述(申请人提供)：身体不满是饮食病理和抑郁的有力预测因素，这是女性在成年初期面临的两个最常见的精神问题。相当多的初露头角的成年人经历过身体不满，但很少有研究系统地调查从青春期后期到初露头角的成年过程中心理社会对身体不满的影响。此外，很少有研究评估男性对身体的不满或病理性肌肉生长的症状。这项研究考察了父母、朋友和浪漫伴侣要求苗条或肌肉发达的压力影响青春期后期身体不满的理论模型，这反过来又会导致抑郁症状、饮食紊乱和成年初期的肌肉形成病理。这一模式将在200名17岁的青少年(50%为男性)及其母亲、密友和浪漫伴侣的社区样本中进行探索。多名记者将被用来评估身体的不满和瘦身和肌肉发达的压力。这些措施还将评估吸引力文化理想的内在化、抑郁症状、饮食紊乱和病理性肌肉建设。扫描电子显微镜将被用来测试压力变瘦/肌肉、身体不满和精神病理学的理论模型。文化理想的内化将被测试为压力和身体不满的调停者。LGCM将研究哪些关系最能预测身体不满程度和随时间变化的情况。这一结果将增强我们对成年初期身体不满的心理社会风险和保护因素的理解，并将有助于改进对患有抑郁症、进食和/或肌肉形成病理风险的新兴成年人的临床预防和干预。

DESCRIPTION (provided by applicant): Body dissatisfaction is a robust predictor of eating pathology and depression, two of the most common psychiatric problems faced by females in emerging adulthood. A significant number of emerging adults experience body dissatisfaction, yet little research has systematically investigated psychosocial influences on body dissatisfaction during the transition from late adolescence to emerging adulthood. In addition, very few studies have assessed males' body dissatisfaction or symptoms of pathological muscle-building. This study examines the theoretical model that parent, friend, and romantic partner pressure to be thin or muscular affect late adolescent body dissatisfaction, which in turn leads to symptoms of depression, disordered eating, and muscle-building pathology in emerging adulthood. This model will be explored in a community sample of 200 17-year-olds (50% male) and their mothers, close friends, and romantic partners. Multiple reporters will be used to assess body dissatisfaction and pressure to be thin and muscular. Measures also will assess internalization of cultural ideals of attractiveness, symptoms of depression, disordered eating, and pathological muscle-building. SEM will be used to test a theoretical model of pressure to be thin/muscular, body dissatisfaction, and psychopathology. Internalization of cultural ideals will be tested as a mediator of pressure and body dissatisfaction. LGCM will examine which relationships are most predictive of levels and changes in body dissatisfaction over time. The results will enhance our understanding of psychosocial risk and protective factors for body dissatisfaction in emerging adulthood and will help to foster improvements in clinical preventions and interventions for emerging adults at risk for depression, eating, and/or muscle-building pathology.
