Over 90% of the 1202 patients investigated in the 9 centres collaborating in the International Pilot Study of Schizophrenia were traced 2 years after the initial examination and on the average over 75% of them were re-examined, using standardized instruments and methods. Results indicate that patients diagnosed as schizophrenic on the basis of standardized assessments and clearly specified diagnostic criteria demonstrated very marked variations of course and outcome over a 2-year period. Schizophrenic patients in the centres in developing countries had considerably better course and outcome than schizophrenic patients in the centres in developed countries.
在参与精神分裂症国际试点研究的9个中心所调查的1202名患者中，超过90%在初次检查2年后被追踪到，平均超过75%的患者接受了重新检查，采用的是标准化工具和方法。结果表明，根据标准化评估和明确规定的诊断标准被诊断为精神分裂症的患者，在2年期间病情过程和预后呈现出非常明显的差异。发展中国家各中心的精神分裂症患者的病情过程和预后明显好于发达国家各中心的精神分裂症患者。
