摘要： 目的·探讨强迫症患者的抑郁症状、归因方式与强迫症状之间的作用关系。方法·以符合《精神疾病诊断与统计手册（第四版）》诊断标准的70例强迫症患者为研究对象，使用耶鲁 - 布朗强迫量表（Yale-Brown Obsessive-Compulsive Scale，Y-BOCS）评估其强迫症状的严重程度，贝克抑郁量表第2版（Beck Depression Inventory- Ⅱ，BDI- Ⅱ）测量其抑郁症状，归因方式问卷（Attributional Style Questionnaire，ASQ）测量其归因方式。分析患者的强迫症状、抑郁症状与归因方式之间的相关性，及强迫症状在其中的中介作用。结果·归因方式中负性事件普遍维度与强迫症状及抑郁症状均呈正相关（均P<0.05），且强迫症状与抑郁症状亦呈正相关（P=0.000）。中介效应分析显示，强迫症状在负性事件普遍维度与抑郁症状间的中介效应大小为0.105（95%CI 0.031～0.218），效应占比为44.20%。结论·强迫症患者的强迫症状可能在归因方式中的负性事件普遍维度与抑郁症状间起完全中介作用。

Abstract:
Objective · To explore the relationship among depressive symptoms, attributional style and obsessive-compulsive symptoms in patients with obsessive-compulsive disorder. Methods · Seventy patients with obsessive-compulsive disorder who met the diagnostic criteria of Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) (DSM- Ⅳ) were selected. The Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) was used to evaluate the severity of obsessive-compulsive symptoms, the Beck Depression Inventor- Ⅱ (BDI- Ⅱ) was used to measure the depressive symptoms, and the Attributional Style Questionnaire (ASQ) was used to measure the attributional style. The correlations among obsessive-compulsive symptoms, depressive symptoms and attributional style as well as the mediating role of obsessive-compulsive symptoms between attributional style and depressive symptoms were analyzed. Results · The globality dimension of negative events in attributional style was positively correlated with obsessive-compulsive symptoms and depressive symptoms (both P<0.05), and obsessive-compulsive symptoms were also positively correlated with depressive symptoms (P=0.000). The mediating effect analysis showed that the mediating role of obsessive-compulsive symptoms between the globality dimension of negative events and depressive symptoms was 0.105 (95%CI 0.031-0.218), with an mediating effect ratio of 44.20%. Conclusion · Obsessive-compulsive symptoms in patients with obsessive-compulsive disorder may play a completely mediating effect between the globality dimension of negative events in attribution style and depressive symptoms.
