Abstract:
Objective 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.
