Recent research suggests specific body image aspects, namely weight/shape dissatisfaction, overvaluation of weight/shape, weight/shape preoccupation, and fear of weight gain, have distinct roles in eating disorder (ED) onset and maintenance. The aim of this study was to investigate unique associations between these body image aspects and ED onset, distress, and quality of life in a community sample of adolescents prospectively after 1 year. Adolescents (n = 1,327; 51% female; age range 11-19 years) who completed Waves 1 and 2 of the EveryBODY Study and did not meet criteria for an ED at Wave 1 completed measures of ED symptoms, distress, and quality of life impairment. Results showed that 18.2% of participants (70% female) met criteria for an ED at Wave 2. Only weight/shape dissatisfaction was prospectively associated with onset of any ED. No other body image aspect was uniquely associated with greater distress nor lower quality of life in longitudinal analyses. However, all body image aspects were independent correlates of ED diagnosis within Wave 2. These findings suggest that dissatisfaction might operate as a risk factor for ED development in adolescence, whereas overvaluation, preoccupation, and fear of weight gain could be more proximal markers of ED psychopathology. Therefore, these body image phenomena should be assessed as separate constructs as they may play unique roles in ED onset and classification. ED prevention efforts in adolescence may need to target dissatisfaction first, whereas a focus on other aspects of body image may be more important for early intervention programs.

身体形象方面在预测一年后青少年饮食失调发作中的独特作用。

最近的研究表明，特定的身体形象方面，即体重/体型不满意、对体重/体型的高估、对体重/体型的关注以及对体重增加的恐惧，在饮食失调 (ED) 的发生和维持中具有不同的作用。本研究的目的是在 1 年后前瞻性地调查青少年社区样本中这些身体形象方面与 ED 发病、痛苦和生活质量之间的独特关联。完成了 EveryBODY 研究的第 1 波和第 2 波但不符合第 1 波 ED 标准的青少年（n = 1,327；51% 为女性；年龄范围为 11-19 岁）完成了对 ED 症状、痛苦和生活质量的测量减值。结果显示，18.2% 的参与者（70% 女性）在第 2 波时符合 ED 的标准。只有体重/体型不满意与任何 ED 的发生前瞻性相关。在纵向分析中，没有其他身体形象方面与更大的痛苦或更低的生活质量相关。然而，所有身体形象方面都是第 2 波中 ED 诊断的独立相关因素。 这些发现表明，不满可能是青春期 ED 发展的一个危险因素，而高估、全神贯注和对体重增加的恐惧可能是更接近的 ED 标志物精神病理学。因此，这些身体形象现象应作为单独的结构进行评估，因为它们可能在 ED 发病和分类中发挥独特的作用。青春期的 ED 预防工作可能需要首先针对不满，而关注身体形象的其他方面对于早期干预计划可能更为重要。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
