Sixty-seven schizophrenic chronic outpatients (DSM-III-R criteria) were examined to study the relationship between symptoms through intercorrelational and factor analysis. Three factors were identified and associated with clusters of symptoms: factor 1 (affective flattening, alogia, avolition-apathy and anhedonia-asociality), factor 2 (formal thought disorder and bizarre behaviour) and factor 3 (hallucinations and delusions). Strong associations between factor 1 and high functional impairment were found. In this population, the segregation of the symptoms could fit into a three-syndrome model, these results agree with findings obtained from samples in which acute symptoms predominated.
对67名慢性精神分裂症门诊患者（符合DSM-III-R标准）进行了检查，通过相互关联分析和因子分析研究症状之间的关系。确定了三个因子，并与症状群相关：因子1（情感平淡、言语贫乏、意志缺乏-淡漠和快感缺失-社交退缩），因子2（形式思维障碍和怪异行为），因子3（幻觉和妄想）。发现因子1与高功能损害之间存在强烈关联。在这一群体中，症状的分离符合三综合征模型，这些结果与以急性症状为主的样本所得结果一致。
