The purpose of the present study is to test interrater reliability of the Japanese version of the Positive and Negative Syndrome Scale (PANSS) and to examine factors possibly affecting the reliability. The study group conducted the PANSS rating on 20 patients with DSM-IV schizophrenia. For the analysis of interrater reliability, intraclass correlation coefficient (ICC) was calculated. The ICC for individual items of the PANSS ranged from 0.26 to 0.92, and those for the positive, negative, and general psychopathology subscales were 0.85, 0.83 and 0.75, respectively. The Cronbach's alpha coefficient for the subscales were 0.84, 0.87 and 0.76, respectively. The interrater reliability and the internal consistency were satisfactory and similar to those obtained in the antecedent studies. No salient training effect was found in a sequential analysis of the concordance rate. It is concluded that the Japanese version of the PANSS is a reliable and efficient tool for comprehensive assessment of the schizophrenic syndrome.
本研究的目的是检验日本版阳性与阴性症状量表（PANSS）的评分者间信度，并探讨可能影响该信度的因素。研究组对20例符合DSM-IV精神分裂症诊断标准的患者进行了PANSS评定。为分析评分者间信度，计算了组内相关系数（ICC）。PANSS各项目的ICC范围为0.26至0.92，阳性、阴性和一般精神病理学分量表的ICC分别为0.85、0.83和0.75。各分量表的Cronbach's alpha系数分别为0.84、0.87和0.76。评分者间信度和内部一致性令人满意，与先前研究结果相似。在一致性率的序贯分析中未发现显著的训练效应。结论是，日本版PANSS是全面评估精神分裂症综合征的可靠且有效的工具。
