精神病高危综合征人群的心理理论特征

目的：探讨精神病高危综合征人群的心理理论特征。方法共纳入140名受试者，其中高危组70名，与之匹配的健康对照70名，分别对两组受试者进行功能大体评定（GAF）、失言觉察任务（FPT）、眼神阅读任务（RMET）评估，比较两组人群心理理论的差异。结果在GAF中，高危组和对照组当前GAF得分（t＝－32．79，P＜0．01）及GAF减分值（t＝27．99，P＜0．01）的差异有统计学意义；在FPT中，高危组的失言故事识别、失言故事理解和对照故事识别得分均低于对照组，差异有统计学意义（P＜0．01）；在RMET中，与对照组相比，高危组的反应时间延迟、反应准确率下降，差异均有统计学意义（P＜0．01）。结论精神病高危综合征人群存在心理理论能力受损。

Theory of Mind in individuals with clinical high risk of psychosis

Objective To investigate the characteristics of Theory of Mind in individuals with high risk of psychosis .Methods A total of 70 participants with high risk of psychosis and 70 controls were involved .Global Assessment Function (GAF)、Faux Pas Text (FPT ) and Reading the Mind in the Eyes Text (RMET) were assessed to examine the Theory of Mind .Results There were significant differences in GAF total score(t= -32 .79 ,P< 0 .01) and GAF subtraction(t= 27 .99 ,P< 0 .01) between two groups .The scores of faux pas story ,faux pas story to understand and control story recognition in high risk group were significantly lower than that of control group (P<0 .01) .The high risk group showed si‐ginificantly longer reaction time and lower response accuracy than control group in RMET (P<0 .01) . Conclusions The Theory of Mind is impaired in individuals with high risk of psychosis .
