中文版修订社会快感缺失量表的信效度

目的 分析中文版修订社会快感缺失量表（RSAS-C）的信度和效度.方法 采用RSAS-C对314名正常健康者和204名精神分裂症患者进行评估,随机抽取75名正常者和102名患者间隔两周后进行重测,评估重测信度,以多伦多述情障碍量表（TAS-20）总分和阳性与阴性症状量表（PANSS）的阴性症状分为效标,计算效标关联效度.结果 信度检验：总样本、患者组和正常组RSAS-C的Cronbach α系数分别为0.787、0.804和0.759;分半信度分别为0.715、0.740和0.676;重测信度分别为0.902、0.916和0.831.效度检验：总样本、患者组和正常组RSAS-C得分与TAS-20总分间的相关系数分别为0.261、0.398和0.154,患者组RSAS-C得分与PANSS阴性症状分的相关系数为0.303,差异有统计学意义（均P＜0.01）.精神分裂症患者RSAS-C得分显著高于正常健康者,表明RSAS-C具有较好的实证效度.结论 RSAS-C有较好的信度和效度,可用于中国正常人群和精神分裂症患者人群快感缺失状况的评估.

Reliability and validity of the Chinese-Version of the Revised Anhedonia Scale

Objective To evaluate the reliability and validity of the Revised Social Anhedonia Scale-Chinese Version （RSAS-C）.Methods 314 healthy subjects and 204 schizophrenic patients were asked to completed the RSAS-C.Two weeks later,75 healthy subjects and 102 schizophrenic patients who were randomly selected from the total sample completed the RSAS-C again to compute the test-retest reliability.The criterion-related validity was evaluated by correlating the RSAS-C with the total score of TAS-20 and the Negative score of PANSS.Results （1） The Cronbach α-coefficient for RSAS-C of total sample,patient group and control group were 0.787,0.804,0.759 respectively.The split half of reliability of those were 0.715,0.740,0.676.And the test-retest reliability of those were 0.902,0.916,0.831.（2） The scores of total sample,patient group and control group for RSAS-C correlated with TAS-20 total score were 0.261,0.398,0.154（all P＜0.01）.The negative score of PANSS correlated with the score for RSAS-C of patient group was 0.303 （P＜ 0.01）.（3） Schizophrenic patients had higher scores of the RSAS-C than the healthy subjects,it suggested that the RSAS-C had good discriminant validity.Conclusion RSAS-C has good reliability and validity in application to Chinese people.
