摘要目的 对精神分裂症认知功能评测量表(Schizophrenia Cognition Rating Scale,SCoRS)中文版的信度和效度进行研究.方法 对112例精神分裂症患者作SCoRS、精神分裂症认知功能简明成套测评量表(BACS)、个人和社会功能量表(PSP)评测.使用主成分分析法、信度分析法及相关分析对所得数据进行统计分析.结果 信度分析显示,Cronbach α=0.963,条目经标准化后Cronbach α=0.964,HotellingT2=248.948,F=10.767,P=0.000,去掉任意一条对信度系数的影响均小于0.01.主成分分析:KMO统计量为0.864.因子分析显示:因子1包括条目1,3,4,5,6,7,8,9,11,反映神经认知功能状态;因子2包括条目10,17,18,19,20,反映社会认知功能状态;因子3包括条目2,12,13,14,15,16,主要反映日常生活功能状态.SCoRS自评分、知情者评分、评定者评分总分与PSP总分及其社会中有益的活动、个人和社会关系、自我照料等因子分均呈中度相关.SCoRS因子分中,除自评分因子3与PSP总分无显著相关性外,余各项之间均存中度显著相关性.SCoRS各评分与扰乱及攻击行为之间不具有显著相关性.SCoRS自评分、知情者评分、评定者评分总分与PSP总分及因子分与BACS复合分及各分测验分之间均呈显著相关性.结论 SCoRS(中文版)是一种良好的认知功能评测工具,适用于汉语地区精神分裂症患者认知功能损害评测.

abstractsObjective To investigate the reliability and validity of the Chinese version of the schizophrenia cognition rating scale ( SCoRS) . Methods 112 cases of schizophrenia or schizophreniform disorder inpatients were recruited and assessed using the SCoRS( Chinese version) ,the brief assessment of cognition in schizophrenia (BACS) and personal and social performance scale(PSP). The principle component analysis,reliability analysis and correlation analysis were used to analyze the data. Results Standardized Cronbach α = 0.964. All the 20 i-tems were significantly correlated. Except item 1 ,9,18,19 ( r=0. 830,0. 890,0. 871,0. 890) ,the interrater correlation coefficiency (ICC) of the rest of the items was over 0.9. The ICC of global rating scores between two raters was 0. 921. Factor analysis procedure identified three factors. Factor 1 reflected the neurocognitive state; factor 2 reflected the social cognitive state;and factor 3 mainly reflected the daily life function. The SCoRS rating scores were significantly correlated with the BACS and PSP scores. Conclusion The validity and reliability of SCoRS are acceptable. SCoRS is a useful tool for assessing the deficits of the cognitive function for Chinese schizophrenia patients.
