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.

身体影像方面在预测一年后青少年进食障碍发作中的独特作用。

最近的研究表明，特定的身体图像方面，即体重/形状不满意，体重/形状的过高估定，体重/形状的过分关注以及对体重增加的恐惧，在进食障碍（ED）发作和维持中具有独特的作用。这项研究的目的是调查在1年后的青少年社区样本中这些身体图像方面与ED发作，困扰和生活质量之间的独特关联。青少年（n = 1,327； 51％的女性；年龄范围11-19岁），他们完成了EveryBODY研究的第1和第2浪，并且在第1浪中未达到ED的标准，从而完成了ED症状，痛苦和生活质量的测量损害。结果显示，在第二波中，有18.2％的参与者（70％为女性）符合ED的标准。只有体重/形状不满意与任何ED的发作均相关。在纵向分析中，没有其他身体图像方面与更大的痛苦或更低的生活质量具有独特的关联。但是，所有身体图像方面都是第二波内ED诊断的独立相关因素。这些发现表明，不满情绪可能是青春期ED发生的危险因素，而过高的评估，专注和对体重增加的恐惧可能是ED的更近端指标。心理病理学。因此，这些身体图像现象应作为单独的构造物进行评估，因为它们可能在ED发作和分类中起独特作用。青春期ED预防工作可能首先需要针对不满，而对身体影像的其他方面的关注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）。
