The present evaluation focused on the inter-rater reliability of single items and subscales of the Positive and Negative Syndrome Scale (PANSS) before and after a standardized rater training. The results of two independent studies comprising n=23 (study I) and n=12 (study II) psychiatrists and videotaped interviews with schizophrenic patients were analysed. Chance-corrected coefficients of rating agreement with expert standards (weighted kappa) were computed for single items and subscales of the PANSS. The results clearly demonstrate the importance of rater trainings. After three training sessions, 90% of the PANSS items reached an acceptable level of reliability (kappa(w)>0.40) in both evaluated studies, and for 80% of the PANSS items values of kappa(w)>0.60 were achieved.
本次评估聚焦于标准化评分者培训前后阳性和阴性症状量表（PANSS）单个条目及分量表的评分者间信度。分析了两项独立研究的结果，这两项研究分别有n = 23名（研究I）和n = 12名（研究II）精神科医生，以及对精神分裂症患者的录像访谈。针对PANSS的单个条目及分量表，计算了与专家标准的机遇校正评分一致性系数（加权kappa）。结果清楚地表明了评分者培训的重要性。在三次培训课程后，在两项评估研究中，90%的PANSS条目达到了可接受的信度水平（kappa(w)>0.40），并且80%的PANSS条目达到了kappa(w)>0.60的值。
