The Delusions-Symptoms-States Inventory (DSSI) was administered to 33 chronic non-paranoid schizophrenic patients resident on long-stay wards. It was found that the vast majority of cases (81 per cent) produced symptom patterns conforming to the hierarchy of classes of personal illness model, but with a radically different distribution among the classes from that in acutely ill patients. Within the model a half of the patients were allotted to the two lowest classes--Class 0 (Symptom-free) and Class 1 (Dysthymic States). When each set of items was considered separately and independently of the model, it was found that a half of the group professed to have recently experienced delusions. Affective states and depressive symptoms were reported by over a third of the patients.
对33名长期住在病房的慢性非偏执型精神分裂症患者进行了妄想-症状-状态量表（DSSI）测试。结果发现，绝大多数病例（81%）呈现出符合个人疾病模型类别层次的症状模式，但各类别之间的分布与急性病患者截然不同。在该模型中，一半的患者被归为两个最低类别——0类（无症状）和1类（心境恶劣状态）。当分别且独立于该模型考虑每组项目时，发现该组中有一半的人声称最近经历过妄想。超过三分之一的患者报告了情感状态和抑郁症状。
