103 patients were admitted for the first time to the psychiatric hospital (Institute of Psychiatry and Neurology in Warsaw) between 1976-1983 and received a research diagnosis of schizophrenia (in accordance with the ICD-9 criteria). The course and clinical pattern of the illness were analyzed at a follow-up in 65 patients--rehospitalized in the 5th year from their first admission. As regards the clinical pattern analysis, it was focused mostly on positive and negative symptoms occurrence, as assessed using the Andreasen Scales (SANS, SAPS). The data obtained from the case reports were statistically tested and the results were presented in the tables according to the research questions. The frequency of occurrence of at least one negative symptom was found to be high in the group under study (in 72% of patients during the first hospitalization and in 83% at the five-years' follow-up). The increment in the frequency of occurrence pertained also to all groups of negative symptoms, which is concordant with many authors, results.
1976年至1983年间，103名患者首次入住华沙精神病学与神经病学研究所的精神病院，并接受了精神分裂症的研究诊断（符合ICD - 9标准）。对65名患者进行了随访分析，这些患者在首次入院后的第5年再次住院，分析了疾病的病程和临床模式。在临床模式分析方面，主要关注使用安德烈亚森量表（SANS，SAPS）评估的阳性和阴性症状的出现情况。对病例报告获得的数据进行了统计检验，并根据研究问题将结果列于表格中。在所研究的组中，发现至少出现一种阴性症状的频率很高（首次住院期间72%的患者出现，五年随访时83%的患者出现）。出现频率的增加也适用于所有阴性症状组，这与许多作者的结果一致。
