背景阳性与阴性症状量表（PANSS）可称为精神分裂症的评定标准。这是众所周知的，并经常使用。在科学研究和临床实践中，通常无法为评分员提供使用量表的广泛培训。问题是，在这种条件下，是否可以保证量表的心理测量特性。法在为期2年的药物利用研究利培酮，1895精神分裂症门诊患者进行了评估，他们的治疗精神科医生，谁是工作条件下的常规护理，使用修改版本的阳性和阴性症状量表（PANSS/m）。医生无法接受使用该量表的培训。对这些评级的结果进行了分析，将平均值和内部一致性与Kay等人的原始结果（Kay等人，精神分裂症阳性和阴性综合征量表（PANSS））进行比较。Schizophr Bull 1987;13：261），并对总样本和分裂样本进行因子分析。结果阳性分量表的平均值相似（分别为6.5和6.4），阴性分量表的平均值（分别为11.9和8.0）略高于Kay等人的原始结果。阳性和阴性分量表的内部一致性（分别为0.80和0.87，以及0.73和0.83）与Kay等人相似。总样本和子样本的析因解相同。讨论各分量表的得分反映了精神分裂症门诊患者阴性症状的优势。阶乘解支持PANSS的阳性和阴性分量表。PANSS/m在常规治疗条件下易于使用，是一种良好且稳健的量表。
Background. The Positive and Negative Syndrome Scale (PANSS) can be called the standard for the assessment of schizophrenic disorders. It is well-known and routinely used. In scientific studies and clinical practice extensive training of raters in the use of the scale can often not be provided. The question is whether under such conditions psychometric properties of the scale can be guaranteed. Method. In a 2-year drug utilization study on risperidone, 1895 schizophrenic outpatients were assessed by their treating psychiatrists, who were working under conditions of routine care, using a modified version of the Positive and Negative Symptom Scale (PANSS/m). Physicians could not be trained in the use of the scale. The results of these ratings were analysed, comparing means and internal consistency with the original Kay et al. results (Kay et al. The positive and negative syndrome scale (PANSS) for schizophrenia. Schizophr Bull 1987;13:261), and by factor analysis for the total sample and split halves. Results. Means for the positive subscale were similar (6.5 and 6.4, respectively) and means for the negative subscale (11.9 and 8.0, respectively) slightly higher than the original Kay et al. results. Internal consistency of the positive and negative subscales (0.80 and 0.87, and 0.73 and 0.83, respectively) were similar to Kay et al. The same clear factorial solution was found for the total sample and the subsamples. Discussion. Scores for the subscales reflect the predominance of negative symptoms in schizophrenic outpatients. The factorial solution supports the positive and negative subscales of the PANSS. The PANSS/m was easy to use under conditions of routine treatment and is a good and robust scale.
