Abstract

Factor analysis was performed on OPCRIT checklist psychotic symptoms rated on 102 patients with DSM-III-R schizophrenia. An initial three-factor solution produced positive, negative, and disorganisation factors. However, application of the scree test suggested five substantive factors, with the positive factor dividing into three factors characterised, respectively, by paranoid symptoms, first rank delusions and first rank hallucinations.

摘要

对102名符合DSM-III-R精神分裂症标准的患者使用OPCRIT检查表评定的精神病症状进行了因子分析。最初的三因子解决方案产生了阳性、阴性和紊乱因子。然而，碎石图检验表明存在五个实质性因子，其中阳性因子又分为分别以偏执症状、一级妄想和一级幻觉为特征的三个因子。
