Despite theoretical propositions regarding the transactional interplay between depressive symptoms and friendship experiences (e.g., Coyne, 1976), few studies have tested interpersonal theories of depression in adolescence. The current study used cross-lagged panel models to test longitudina, reciprocal associations of adolescents' depressive symptoms with self- and friend-reported positive friendship quality, conflict, and detachment over 3 time points spanning 6 months in a community sample (N = 186; 69.9% female; 87.6% White; Mage = 15.68 years). Gender and age differences were also considered. Results support theories positing both friendship- and symptom-driven change for associations between depressive symptoms and positive quality, whereas detachment predicted a cycle of increased depressive symptoms and later increased detachment. Moreover, only adolescents' (not friends') perceptions of friendship were linked with adolescents' depressive symptoms. Implications for future research on interpersonal theories of depression and for intervention efforts to reduce depressive symptoms and support adolescents' relationships are discussed.

尽管有关于抑郁症状和友谊经历之间交易相互作用的理论命题（例如，Coyne，1976），但很少有研究检验青春期抑郁的人际关系理论。当前的研究使用交叉滞后的面板模型测试了社区样本中3个时间点的经度，青春期抑郁症状与自我和朋友报告的积极友谊质量，冲突和脱离的相互关系（N  = 186） ; 69.9％女性; 87.6％白色; M年龄= 15.68岁）。还考虑了性别和年龄差异。结果支持理论，该理论假设友谊和症状驱动的变化可导致抑郁症状与阳性质量之间的关联，而超脱则预示着抑郁症状加重且后来超脱现象增加的周期。而且，只有青少年（而非朋友）的友谊观与青少年的抑郁症状有关。讨论了对人际关系抑郁理论的未来研究以及减轻抑郁症状和支持青少年关系的干预措施的意义。
