Eighty inpatients and 20 outpatients with ICD-10 schizophrenia were assessed with the Manchester Scale (MS) and the scale for the assessment of Subjective Experience of Deficits in Schizophrenia (SEDS). A factor analysis on MS scores yielded a three-factor solution: negative symptoms, positive symptoms, and anxious-depressive factor. On the other hand, a factor analysis on SEDS scores provided a seven-factor solution. The first factor, "awareness of social incompetence (ASI)," positively correlated with the anxious-depressive factor. ASI may reflect a negative cognitive attitude of persons who easily become depressive. The second factor, "subjective cognitive disturbance (SCD)," positively correlated with the positive-symptoms factor. SCD might represent a subtle disturbance, which can also produce positive symptoms. We found no factor on SEDS that correlated with the negative-symptoms factor. It was noted that a selection and comparison of items and the cultural background of subjects should be considered.
对80名住院患者和20名患有国际疾病分类第十版（ICD - 10）精神分裂症的门诊患者，采用曼彻斯特量表（MS）和精神分裂症缺陷主观体验评估量表（SEDS）进行评估。对MS评分进行因子分析得到一个三因子解：阴性症状、阳性症状和焦虑抑郁因子。另一方面，对SEDS评分进行因子分析得到一个七因子解。第一个因子“社交无能意识（ASI）”与焦虑抑郁因子呈正相关。ASI可能反映了容易抑郁者的消极认知态度。第二个因子“主观认知障碍（SCD）”与阳性症状因子呈正相关。SCD可能代表一种细微的障碍，也可产生阳性症状。我们发现SEDS中没有与阴性症状因子相关的因子。需要注意的是，应考虑项目的选择和比较以及受试者的文化背景。
