This study tested the diathesis-stress component of Beck's (1967) cognitive theory of depression. Initially, participants completed measures assessing cognitive organization of the self-schema and depressive symptoms. One year later, participants completed measures assessing cognitive organization of the self-schema, depressive symptoms, and negative life events. Hierarchical multiple regression analyses, controlling for initial depression, indicated that more tightly interconnected negative content was associated with greater elevations in depressive symptoms following the occurrence of life events. More diffusely interconnected positive content for interpersonal self-referent information also interacted with life events to predict depressive symptoms. Cognitive organization dimensions showed moderate to high stability across the follow-up, suggesting that they may be trait-like vulnerability factors. Implications for the cognitive vulnerability-stress model of depression are discussed.
本研究检验了贝克（1967）抑郁认知理论中的素质-应激成分。最初，参与者完成了评估自我图式认知组织和抑郁症状的测量。一年后，参与者完成了评估自我图式认知组织、抑郁症状和负面生活事件的测量。在控制初始抑郁的情况下，层次多重回归分析表明，在生活事件发生后，与抑郁症状升高相关的是更加紧密互联的消极内容。人际自我参照信息的更广泛互联的积极内容也与生活事件相互作用，从而预测抑郁症状。认知组织维度在随访中表现出中等至高度的稳定性，表明它们可能是特质性的脆弱因素。讨论了抑郁的认知易损性-应激模型的含义。
