To our knowledge, there have been no published studies validating commonly used psychopathology rating scales in older outpatients with schizophrenia. We studied specific psychopathology rating scales (three subscales of the Brief Psychiatric Rating Scale: positive symptoms, negative symptoms, and depression subscales; the Scale for Assessment of Positive Symptoms; the Scale for the Assessment of Positive Symptoms; the Scale for the Assessment of Negative Symptoms; and the Hamilton Depression Rating Scale) in 101 (age > 45 years) DSM-III-R-diagnosed schizophrenia outpatients. We found high interrater reliability (intra-class correlated coefficient > or = .77) on these scales. Using principal components analysis, we demonstrated satisfactory construct validity, suggesting three factors-positive symptoms, negative symptoms, and depressive symptoms.
据我们所知，尚无已发表的研究对老年精神分裂症门诊患者常用的精神病理学评定量表进行验证。我们对101名（年龄>45岁）经DSM-III-R诊断的精神分裂症门诊患者研究了特定的精神病理学评定量表（简明精神病评定量表的三个分量表：阳性症状、阴性症状和抑郁分量表；阳性症状评定量表；阳性症状评定量表；阴性症状评定量表；以及汉密尔顿抑郁评定量表）。我们发现这些量表具有较高的评定者间信度（组内相关系数≥0.77）。通过主成分分析，我们证明了其具有令人满意的结构效度，提示三个因素——阳性症状、阴性症状和抑郁症状。
