摘要
目的:对用于测定精神分裂症患者阴性症状的简明阴性症状量表中文版(BNSS-C)的临床效度、信度进行检验.方法:经原作者同意,汉化英文版BNSS.选取163例诊断符合国际疾病和相关健康问题统计分类第十版(ICD-10)精神分裂症诊断标准的住院和社区慢性患者,进行BNSS-C、阴性症状量表(SANS)及阳性与阴性症状量表(PANSS)的评定.随机选取其中43例患者间隔2周进行BNSS-C测量,用于计算重测信度.在住院患者中选取7例患者,由5名主试共同评定,用于计算评定者间信度.结果:全部受试完成BNSS-C半结构式访谈.量表的标准化Cronbachα值为0.93,5个分量表的Cronbachα值在0.86~0.95间;量表的重测信度为0.82,评定者间信度为0.93.因子分析获得主观体验缺损和情感表达缺损2个因子,共解释了总方差的71.6%;BNSS-C总分与PANSS总分、PANSS阴性症状分、SANS总分均正相关(r =0.24 ~0.77,P<0.01).以SANS除认知维度外的4个维度(情感平淡或迟钝;思维贫乏;意志缺乏;兴趣/社交缺乏)任一维度总评分≥3为标准,将受试分为阴性症状组和非阴性症状组,测得BNSS量表的灵敏度为69.6% (95%CI:0.50~0.83),特异度为85.0% (95%CI:0.78~0.90).结论:简明阴性症状量表中文版具有可接受的计量心理学特征,可应用于中国文化背景下慢性精神分裂症患者阴性症状的评估.
Objective: To test the validity and reliability of the Chinese version of the Brief Negative Symp- tom Scale (BNSS-C), which is used to assess the negative symptoms in schizophrenia patients. Methods: With au- thorized permission by the author, the BNSS was translated into Chinese and adapted. Totally 163 inpatients and chronic outpatients meeting the diagnosis criteria for schizophrenia according to the International Classification of Diseases and Related Health Problems, Tenth Revision (ICD-10) were recruited and tested with the BNSS-C, SANS and PANSS. Another 43 patients randomly selected received test and retest of BNSS-C at 2 weeks interval for the test-retest reliability. Seven inpatients were assessed by 5 examiner for the inter-tester reliability. Results: All pa- tients completed the BNSS-C. The Cronbach alpha were 0.93 for the BNSS-C total score and 0. 86 -0.95 for the 5 subscales. The test-retest reliability coefficient and inter-tester reliability coefficient were 0. 82 and 0. 93 ( P 〈 0. 001). The Exploratory factor analysis revealed a two-factor (impairment of subjective experience and impairmentof observable behavior) solution that accounted for 71.63% of the variance. The BNSS-C total scores were posi- tively correlated with the PANSS total scores, PANSS negative scale scores and SANS total scores (r = 0. 24 - 0. 77, P 〈0. 001). Sensitivity and specificity for the combination of the BNSS dimensions using the SANS index were 69. 6% (0. 50 -0. 83) and 85.0% (0. 78 -0. 90), respectively. Conclusion: The reliability and validity of the BNSS-C meet psychometrics requirements for assessing negative symptoms in Chinese chronic patients with schizo- phrenia.
