Late Adolescent Body Dissatisfaction and Psychopathology

描述（由申请人提供）：身体不满意是饮食病理和抑郁症的一个强有力的预测因子，这是女性在成年初期面临的两个最常见的精神问题。大量的新兴成年人经历身体不满，但很少有研究系统地调查从青春期后期到成年期的过渡期对身体不满的心理社会影响。此外，很少有研究评估男性对身体的不满或病理性肌肉增生的症状。这项研究探讨了理论模型，父母，朋友和浪漫的伴侣压力是薄或肌肉影响青少年后期的身体不满，这反过来又导致抑郁症的症状，饮食失调，肌肉建设病理在成年初。该模型将在200名17岁的青少年（50%为男性）及其母亲，亲密朋友和浪漫伴侣的社区样本中进行探索。将使用多名报告者来评估身体不满和压力，以保持苗条和肌肉发达。这些措施还将评估吸引力的文化理想的内在化，抑郁症的症状，饮食失调和病理性肌肉锻炼。SEM将用于测试瘦/肌肉压力、身体不满和精神病理学的理论模型。文化理想的内化将作为压力和身体不满的调解人进行测试。LGCM将研究哪些关系最能预测身体不满意度的水平和变化。研究结果将增强我们对成年后身体不满意的心理社会风险和保护因素的理解，并将有助于促进改善临床预防和干预措施，为有抑郁症，饮食和/或肌肉建设病理风险的成年人提供帮助。

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.
