强迫症症状分类量表(修订版)中文版的信效度研究

摘要

Objective: To examine the reliability and validity of Chinese version of obsessive-compulsive inventory ( OCI-R) . Method:299 undergraduate students and 90 patients with obsessive-compulsive disorder ( OCD) were evaluated using Yale-Brown obsessive-compulsive scale ( Y-BOCS) by psychiatrist individual ly and finished OCI-R. After a 4-weeks interval the questionnaire was retested in 44 patients with OCD. ResultS:The retest reliability and Cronbach^ alpha reliability coefficients of total score were 0. 690(P <0. 05) and 0. 88, respectively. The confirmatory factor analysis result: x2 = 403. 07, v = 120, n = 299; GFI = 0. 87, RM SEA =0. 086;CFI =0. 96;NNFI =0. 95. Each item scores and subscale score were correlated with total score of OCI-R significantly (r =0. 450 ~0. 660,P <0. 01 ;r =0. 662 ~0. 782,P <0.01 .respectively). The total score of OCI-R was positively associated with that of Y-BOCS in the sample of patients with OCD( n = 90) ( r = 0. 422, P <0.01). Conclusion: Reliability and validity of the Chinese version of obsessive-compulsive inventory-re vised meet psychometric standard, and it could be an effective instrument for measuring obsessive-compulsive disorders in Chinese context.%目的:评价中文版强迫症症状分类量表(修订版)(OCI-R)在正常人群和强迫症患者中的信、效度.方法:采用中文版耶鲁-布朗强迫症量表(Y-BOCS)对299例在校大学生及90例强迫症患者进行评定,同时要求每位被试者自行完成OCI-R中文版的评估.其中44名强迫症患者于4周后进行再次测试.结果:OCI-R中文版Cronbach's alpha=0.88,重测信度r=0.690(P ＜0.05).OCI-R验证性因素分析结果:X2=403.07,v=120,n=299;拟合优度指数(GFI)=0.87;近似误差均方根(RMSEA)=0.086；比较拟合指数(CFI)=0.96；非标准拟合参数(NNFI)=0.95.OCI-R各条目在总量表中的负荷值r =0.450～0.660(P ＜0.01),各维度在总量中的负荷值r=0.662 ～0.782(P ＜0.01).强迫症患者中OCI-R总分与Y-BOCS总分之间相关系数r=0.422(P＜0.01).结论:OCI-R(修订版)中文译本具有良好的信效度,符合心理测试要求,可适用于中国人群强迫症状的测量.
