目的 :以阳性和阴性症状量表 (PANSS)中文版为基础 ,进一步分析其心理测量特质 ,并简要介绍临床应用。方法 :选取 10 5例诊断符合国际疾病分类手册第 10版 (ICD -10 )中精神分裂症标准的患者进行PANSS评定 ,对原始评定结果进行因子分析、信度分析。结果 :因子分析提出 5个因子 ,分别是 :阴性症状、阳性症状、兴奋敌对、焦虑抑郁、认知缺损 ;信度分析显示量表的标准化Cronbachα值为 0 870 7,5个维度的Cronbachα值在 0 743 4-0 90 44间 ,项目间具有内在的一致性。结论 :PANSS中文版有较好的信、效度 ,适用于精神分裂症症状的量化评估。

Objective:To study the reliability, validity of PANSS(Chinese version) and its implication.Methods:105 schizophrenic patients were recruited and were evaluated using PANSS. The principle component analysis and reliability analysis were used to study the factor structure and internal reliability, homogeneity among items.Results:Factor analysis resulted in a five-factor: negative, positive, excitement-hostile, anxiety/depression, cognitive defect. The internal consistency reliability was 0.87 (Cronbach α). The internal consistency reliability of the 5 dimensions ranged from 0.74～0.90.Conclusion:The structure, validity and reliability of PANSS (Chinese version) are acceptable. PANSS can be used to assess the symptoms of schizophrenia in Chinese patients.
