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).
前瞻性研究发现，社会支持不足与未来进食障碍症状的增加之间存在不一致的关系。此外，尚无前瞻性研究测试过升高的进食障碍症状是否预示着未来社会支持的减少。因此，本研究调查了青少年女孩感知到的来自父母和同伴的社会支持与进食障碍症状之间的前瞻性互惠关系。在这项研究中，496 名青少年女孩报告了感知到的社会支持，并在 7 年内每年完成一次进食障碍诊断访谈。感知到的同伴支持不足，但不是父母支持不足，预测了未来进食障碍症状的增加（p =.019，偏相关系数 = -.10）。此外，初始进食障碍症状预测了未来感知到的同伴支持的减少（p =.016，偏相关系数 = -.11），但不是父母支持。有趣的是，当我们控制了负面情绪和体重指数时，这些关系变得不显著，这表明共患情绪障碍和体重升高可能部分导致了这些关系。虽然这两种关系的程度都很小，但这些结果表明，低水平的感知到的同伴支持是未来进食障碍症状恶化的危险因素，而升高的症状可能导致同伴支持的进一步减少，从而形成维持进食障碍的循环关系。相反，高水平的感知到的同伴支持可以作为预防未来进食障碍增加的保护因素。这些发现应该推进进食障碍的人际理论，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）。
