中文版修订躯体快感缺失量表的信度和效度

Reliability and Validity of Chinese Version of Revised Physical Anhedonia Scale

目的对中文版修订躯体快感缺失量表(RPAS-C)的信度和效度作初步分析。方法采用RPAS-C对202名精神分裂症患者及311名正常人进行评估,2周后随机抽取其中100名精神分裂症患者和74名正常人进行重测。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)的阴性症状分为校标,计算校标关联效度。结果总样本RPAS-C的Cronbach'sα系数为0.850,分半信度为0.796,重测信度为0.909,患者组与正常组的Cronbach'sα系数、分半信度和重测信度趋于一致;患者组RPAS-C得分高于正常组,差异具有统计学意义(P<0.01);总样本、患者组和正常组RPAS-C得分与述情障碍总分间的相关系数分别为0.316、0.422和0.237,患者组RPAS-C得分与PANSS阴性症状分的相关系数为0.448,具有显著统计学意义(均P<0.01)。结论 RPAS-C具有较好的信度和效度,可用于中国精神分裂症患者人群和正常人群躯体快感缺失的评估。

Objective To develop a cross-culture revision of Revised Physical Anhedonia Scale( RPAS) and evaluate its reliability and validity of the Chinese version. Methods A total of 202 schizophrenic patients and 311 healthy subjects were measured with a selfrating instrument,Chinese version of Revised Physical Anhedonia Scale( RPAS- C); 100 schizophrenic patients and 74 healthy subjects were retested by RPAS- C. The criterion- related validity was evaluated by correlating the RPAS- C with the total score of TAS- 20 and the Negative score of PANSS. Results The Cronbach's α of RPAS- C was 0. 850 in total sample,the split half of reliability was 0. 796,and the test-retest reliability was 0. 909( P < 0. 01); The patient group and the normal group tended to be coincide. The patient group had higher scores of RPAS- C than the normal group,and the difference was statistically significant( P < 0. 01). The total score of TAS- 20 was positively associated with that of RPAS- C in the total sample,the patient group and the normal group,the correlation coefficients were 0. 316,0. 422 and 0. 237; The negative score of PANSS was correlated with the score of RPAS- C which completed by patients( r = 0. 448,P < 0. 01). Conclusion RPAS- C has good reliability and validity,it can be used to assess physical anhedonia of Chinese patients with schizophrenia and normal population.
