Patients who meet DSM-III criteria for schizophrenia were compared with those who meet DSM-II, but not DSM-III, criteria. Comparisons included measures of positive symptoms, negative symptoms, and social competence both before extended hospitalization and during a 7-year follow-up. The measure of positive symptoms was the only variable that differed significantly between groups at initial assessment. Positive symptoms were more stable and predictive for DSM-III schizophrenics than for DSM-II schizophrenics. The measure of negative symptoms was the most stable and predictive variable for the DSM-II schizophrenics. Increased homogeneity for the DSM-III schizophrenics was not found for most measures.
将符合精神分裂症DSM-III标准的患者与符合DSM-II但不符合DSM-III标准的患者进行了比较。比较内容包括在长期住院前以及7年随访期间的阳性症状、阴性症状和社交能力指标。阳性症状指标是初始评估时两组之间唯一有显著差异的变量。与DSM-II精神分裂症患者相比，阳性症状在DSM-III精神分裂症患者中更稳定且更具预测性。阴性症状指标对DSM-II精神分裂症患者来说是最稳定且最具预测性的变量。对于大多数指标而言，未发现DSM-III精神分裂症患者的同质性增加。
