The association between disordered eating and depression has been established, but less is known about the temporal relations between these two disturbances. Accordingly, the current study examined the reciprocal relations between depressive and bulimic symptoms over an 8-year period, with longitudinal data from a community sample of 496 female adolescents. Depressive symptoms predicted future increases in bulimic symptoms, and bulimic symptoms likewise predicted increases in depressive symptoms, controlling for earlier levels of symptoms for each outcome. These results provide evidence consistent with the hypothesis that the two disorders contribute reciprocally to each other, and indicate that successful prevention or treatment of one disorder may yield effects for the other. However, the relatively small predictive effect sizes imply that some third variable may contribute to both conditions (e.g., temperamental negative affectivity).
饮食失调与抑郁症之间的关联已经确立，但对于这两种紊乱之间的时间关系却知之甚少。因此，本研究利用来自496名女性青少年社区样本的纵向数据，考察了8年间抑郁症状与暴食症状之间的相互关系。抑郁症状预示着未来暴食症状会增加，而暴食症状同样预示着抑郁症状会增加，同时对每个结果的早期症状水平进行了控制。这些结果提供了与以下假设一致的证据，即这两种障碍相互作用，并且表明成功预防或治疗其中一种障碍可能会对另一种障碍产生影响。然而，相对较小的预测效应量意味着可能有某个第三变量导致了这两种情况（例如，气质性消极情感）。
