The authors investigated the factors relating to the observation that in a large state hospital, there is an age-related increase in the ratio of patients with a DSM-II diagnosis of paranoid schizophrenia to those with a diagnosis of nonparanoid schizophrenia. Elderly inpatients (N = 1,518) treated over a 5-year period were studied and the hypotheses of proportionately greater numbers with late onset of paranoid conditions, longer lengths of stay for recently admitted paranoid patients, and changing diagnosis over time were tested and rejected. The data suggest that the buildup among the elderly of those diagnosed under DSM-II to have paranoid conditions is due to patients admitted well before age 54. The authors discuss the reasons for the poor prognosis of this group.
在一家大型州立医院，被诊断为偏执型精神分裂症（DSM-II诊断标准）的患者与被诊断为非偏执型精神分裂症的患者之比呈现出与年龄相关的增长。研究了在5年期间接受治疗的老年住院患者（N = 1518），并对偏执型疾病起病较晚的患者比例更高、近期入院的偏执型患者住院时间更长以及诊断随时间变化的假设进行了检验并予以否定。数据表明，按照DSM-II诊断为患有偏执型疾病的老年人增多是由于54岁之前就已入院的患者。作者讨论了该组患者预后不良的原因。
