强迫症症状分类量表(修订版)中文版的信效度研究

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’salpha=0.88,重测信度r=0.690(P<0.05)。OCI-R验证性因素分析结果:χ2=403.07,ν=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。

Reliability and validity of Chinese version of obsessive-compulsive inventory-revised

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 individually and finished OCI-R.After a 4-weeks interval the questionnaire was retested in 44 patients with OCD.Results:The retest reliability and Cronbach’s alpha reliability coefficients of total score were 0.690(P<0.05)and 0.88,respectively.The confirmatory factor analysis result:χ2=403.07,ν=120,n=299;GFI =0.87,RMSEA=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-revised meet psychometric standard,and it could be an effective instrument for measuring obsessive-compulsive disorders in Chinese context.
