摘　　要：目的:考察精神分裂症患者的未来想象在具体性、情绪效价、内容三个方面存在的缺损。方法:选取符合美国精神障碍诊断与统计手册第4版(DSM-IV)诊断的精神分裂症患者25名,选取在性别、年龄、受教育年限、IQ上相匹配的健康者25名作为正常对照,通过未来事件句子补全任务,探讨精神分裂症患者未来想象能力的缺损。结果:与正常对照相比,精神分裂症患者在进行未来情景想象时,想象的事件过于泛化,缺乏具体性信息[(0.13±0.10)vs.(0.31±0.12),P<0.01],在控制了工作记忆、言语记忆等功能后,缺损仍然存在[F(1,54)=6.60,P<0.05];在情绪方面,精神分裂症患者的积极情绪想象较少[(0.36±0.20)vs.(0.48±0.16),P<0.01];在内容方面,精神分裂症患者更多的想象和住院有关[0(0,0.64)vs.0,P<0.01]以及无法分类的事件[0.36(0.09,0.64)vs.0.09(0,0.36),P<0.01]而较少的想象和个人事业有关的事件[0(0,0.27)vs.0.18(0,0.45),P<0.01]。结论:本研究结果表明精神分裂症患者的未来想象在具体性上存在缺损。此外,精神分裂症患者想象的事件较为消极。Objective：To investigate the episodic future thinking in patients with schizophrenia from three per-spectives including the specificity,emotional valence,and content.Methods：Totally 25 patients with schizophrenia who met the Diagnostic and Statistical Manual of Mental Disorder,Fourth Edition （DSM-Ⅳ）criteria and 25 healthy controls matched with gender,age,and years of education participated in this study.The Sentence Completion for E-vents in the Future Test （SCEFT）was used to test episodic future thinking.Results：Schizophrenia patients showed deficits in episodic future thinking[（0.13 ±0.10）vs.（0.31 ±0.12）,P 〈0.01].They had problems in imaging the specific events even after controlling for working memory and verbal memory [F（1,54）=6.60,P 〈0.05].More-over,they generated less positive events compared with the healthy controls [（0.36 ±0.20）vs.（0.48 ±0.16）,P 〈0.01].As to the content,schizophrenia patients generated more events about hospitalization [0 （0,0.64）vs.0,P 〈0.01],more events that were unclassifiable [0.36 （0.09,0.64）vs.0.09 （0,0.36）,P 〈0.01],and less events re-lated with personal career [0 （0,0.27）vs.0.18 （0,0.45）,P 〈0.01].Conclusion：It suggests that schizophrenia patients show deficits in episodic future thinking.They have problems in imaging the specific events,and they have more negative thinking.
