摘要:
目的 考察阴性症状自评量表(SNS)中文版的效度和信度,为精神分裂症患者阴性症状 的评定提供有效和实用的新工具。方法 选取符合美国精神障碍诊断与统计手册第4 版(DSM- Ⅳ)诊断 标准的住院精神分裂症患者120 例,进行认知功能成套测验(MCCB)的评定,选取认知功能保存相对完 好(总分≥ 40 分)的患者79 例,进行SNS、简明阴性症状量表(BNSS)、阳性与阴性症状评估量表(PANSS) 及卡尔加里抑郁量表(CDSS)评定,来评估量表的结构效度、关联效度和内部一致性信度;2 周后,随机 选取其中30 例患者进行重测。结果 探索性因子分析抽取主观体验缺损和情感表达缺损2 个因子,共 解释总方差的72.56%。效度分析表明,SNS 总分与BNSS 总分、PANSS 阴性症状分、PANSS 总分正相关 (r=0.36、0.26、0.30,P< 0.05),各维度分与BNSS总分正相关(r=0.25~0.37,均P< 0.05)。量表内部一致 性系数为0.88,各维度内部一致性系数介于0.58~0.76;量表重测信度(ICC)为0.79,各维度的ICC分别 为0.42、0.82、0.41、0.81、0.34(P< 0.01)。结论 阴性症状自评量表中文版具备较好的心理计量学特征, 可以用于临床量化评估具备一定认知功能的精神分裂症患者的阴性症状。

Abstract:
Objective To explore the reliability and validity of Chinese version of the Self-Evaluation of Negative Symptoms( SNS), so as to provide an effective and practical new tool for the assessment of negative symptoms in schizophrenia. Methods Totally 120 inpatients with schizophrenia meeting the diagnosis criteria of Diagnostic and Statistical Manual of Mental Disorders, Fourth Education( DSM-Ⅳ) were recruited and tested with MATRICS Consensus Cognitive Battery( MCCB). 79 patients with relatively good cognitive function( total score ≥ 40) were evaluated by SNS, Brief Negative Symptom Scale( BNSS), Positive and Negative Symptom Assessment Scale( PANSS) and Calgary Depression Scale( CDSS), to evaluate the construct validity, relevance validity and internal consistency reliability of the scale. 30 inpatients of them were randomly selected and retested after 2 weeks. Results The exploratory factor analysis revealed a two-factor( impairment of subjective experience and impairment of observable behavior) solution that accounted for 72.56% of the variance. Validity analysis showed that the total score of SNS was positively correlated with BNSS, PANSS negative symptoms and PANSS( r=0.36,0.26,0.30,P < 0.05), and each dimension score was positively correlated with BNSS total score( r=0.25-0.37, all P<0.05). The Cronbach's alpha for the SNS total score was 0.88 and for 5 subscales were between 0.58-0.76. The test-retest reliability coefficient for the SNS total score was 0.79( P<0.001) and for 5 subscales were between 0.34-0.82( P< 0.01). Conclusions The Chinese version of the SNS has good psychometric characteristics and can be used to quantitatively evaluate the negative symptoms of schizophrenia patients with certain cognitive function.
