Prospective studies have found inconsistent relations between social support deficits and future increases in eating disorder symptoms. Furthermore, no prospective study has tested whether elevated eating disorder symptoms predict a future erosion of social support. Accordingly, the current study investigated the prospective reciprocal relations between perceived social support from both parents and peers and eating disorder symptoms in adolescent girls. In this study, 496 adolescent girls reported perceived social support and completed an eating disorder diagnostic interview annually for 7 years. Deficits in perceived peer, but not parental, support predicted future increases in eating disorder symptoms (p = .019, partial r = -.10). Furthermore, initial eating disorder symptoms predicted future reductions in perceived peer support (p = .016, partial r = -.11) but not parental support. Interestingly, these relations became nonsignificant when we controlled for negative affect and body mass index, suggesting that comorbid mood disorders and elevated body weight might partially drive these relations. Although both relations were small in magnitude, these results suggest low perceived peer support is a risk factor for future escalations in eating disorder symptoms and that elevated symptoms may contribute to a further erosion of peer support, creating a cyclical relation that maintains eating pathology. Conversely, high levels of perceived peer support could serve as a protective factor against future increases in eating pathology. These findings should advance interpersonal theories of eating pathology and inform the design of more effective prevention programs. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

社会支持与饮食失调症状之间的前瞻性相互关系。

前瞻性研究发现，社会支持缺陷与未来饮食失调症状的增加之间存在不一致的关系。此外，还没有前瞻性研究测试饮食失调症状的加重是否预示着未来社会支持的侵蚀。因此，当前的研究调查了青春期女孩从父母和同龄人那里获得的社会支持与饮食失调症状之间的预期相互关系。在这项研究中，496 名青春期女孩报告了所感受到的社会支持，并在 7 年内每年完成一次饮食失调诊断访谈。感知到的同伴支持（而非父母支持）的缺陷预示着未来饮食失调症状的增加（p = .019，部分 r = -.10）。此外，最初的饮食失调症状预示着未来感知到的同伴支持会减少（p = .016，部分r = -.11），但不能预测父母支持。有趣的是，当我们控制负面情绪和体重指数时，这些关系变得不显着，这表明共病情绪障碍和体重升高可能部分驱动这些关系。尽管这两种关系的幅度都很小，但这些结果表明，感知到的同伴支持度低是未来饮食失调症状升级的一个风险因素，而症状的升高可能会导致同伴支持的进一步削弱，从而形成一种维持饮食病理学的周期性关系。相反，高水平的同伴支持可以作为防止未来饮食病理增加的保护因素。这些发现应该推进饮食病理学的人际理论，并为更有效的预防计划的设计提供信息。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
