This study provides a description of replicated findings of limited heterogeneity in DSM-III schizophrenics. Based now on a sample of 145 schizophrenics, in 1984 and 182 in 1991 it is suggested that the diagnosis is primarily given to chronic patients with poor prognoses, in turn restricting the utility of a process-reactive conceptualization of schizophrenia.
本研究描述了对精神分裂症诊断与统计手册第三版（DSM-III）中精神分裂症患者有限异质性的重复研究结果。基于1984年的145名精神分裂症患者样本以及1991年的182名患者样本，研究表明该诊断主要针对预后较差的慢性病患者，这反过来限制了精神分裂症过程反应性概念化的效用。
