One hundred and fifty-five DSM-IIIR schizophrenic patients were assessed for positive and negative symptoms using Andreasen's Scale for Assessment of Positive Symptoms (SAPS) and the Scale for Assessment of Negative Symptoms (SANS). Interrelationships of individual positive and negative symptoms were examined using a factor analysis. Results of the factor analysis are consistent with Liddle's proposition that there are three syndromes underlying symptomatology in schizophrenia: disorganization; psychomotor poverty and reality distortion.
使用安德烈亚森阳性症状评定量表(SAPS)和阴性症状评定量表(SANS)对155名DSM-IIIR精神分裂症患者的阳性和阴性症状进行评估。使用因子分析检查个体阳性和阴性症状之间的相互关系。因子分析结果与利德尔的观点一致,即精神分裂症症状学背后存在三种综合征:紊乱;精神运动性迟钝和现实扭曲。
