摘　　要：目的:探讨分裂型人格障碍者的社会认知功能特征。方法:应用分裂型人格问卷(schizotypal personality questionnaire,SPQ)从某大学2007年度入学的4461名大学生中筛选SPQ高分者(总分>38分),应用DSM-IV轴II人格障碍用临床定式访谈版(Structured Clinical Interview for DSMIV Axis Ⅱ,SCIDⅡ)进行面谈,并据DSM-IV诊断标准确定分裂型人格障碍(schizotypal personality disorder,SPD)者。共41名SPD者、53名SPQ高分者(不符合任何人格障碍标准)和37名对照组学生(SPQ≤18的低分者)完成本研究。应用Ekman标准面孔库中的面孔生成刺激材料,研究受试的面孔不同程度性别识别(分低、中、高3等程度的男女识别)和面孔不同程度表情识别(分低、中、高3等程度的高兴、厌恶和恐惧情绪的识别)能力,分析其判断正确率。结果:(1)性别识别。总体正确率在3组之间差异无统计学意义(F=0.71,P=0.494);组别与性别程度之间有交互作用(F=3.83,P=0.016),后续分析发现仅在低程度男性面孔识别正确率方面3组之间存在差异(F=3.40,P=0.036),进一步两两比较显示,SPD组的判断正确率明显低于对照组[(21.13±20.86%)vs.(35.43±30.15%),P=0.010];(2)表情识别。总体正确率在3组之间差异有统计学意义(F=3.44,P=0.035),SPD组的正确率低于对照组[(45.14±18.21%)vs.(54.66±18.24%),P=0.039];组别与表情程度之间存在交互作用(F=3.04,P=0.044),在中等程度高兴和中等程度厌恶表情识别方面上,对照组正确率均高于其他2组[(73.64±28.64)vs.(71.34±20.34)、(57.46±31.96),(60.13±28.04)vs.(52.94±24.44)、(43.44±22.22);均P<0.05]。结论:分裂型人格障碍患者的面孔表情识别能力受损,提示他们可能存在社会认知功能障碍。Objective： To explore the characteristic of social cognition of schizotypal personality disorder （SPD） . Methods： SPD subjects were screened from 4461 freshmen in a Shanghai university in 2007 with the Raine＇s schizotypal personality questionnaire （SPQ） . High SPQ scorers were defined as those top 10 percent of SPQ scores and they were interviewed by psychiatrists with the Structured Clinical Interview for DSM-IV Axis Ⅱ （ SCID- Ⅱ）, and were diagnosed according to the DSM-IV criteria. There were three groups, including the SPD group （n =41 ）, the control group of students with a SPQ score in low 10 percent （n =37）, and the high SPQ group of students with the high SPQ score but without any DSM-IV personality disorder diagnosis （ n = 53 ） . Social cognition was investigated using facial emotion and gender recognition tasks, which was designed using the Ekman Standard Faces Database. Result： （ 1 ） Facial gender recognition. There was no significant difference in total accura- cy among the three groups （ F =0. 71, P =0. 494 ）, but the interaction of group with facial gender intensity was significant （F = 3. 83, P = 0. 016 ）, and post hoc test revealed that SPD group performed significantly worse than the control group and the high SPQ group on low intensity male facial recognition [ （21.13 ±20. 86} % vs. （35. 43 ±30. 15）%, P =0. 010 ] . （2） Facial emotional expression recognition. There was significant difference in total accuracy among the three groups （ F = 3.44, P = 0. 035 ）, and it was lower in SPD group than in the control group [ （45.14 ± 18. 21 ） % vs. （54. 66 ± 18. 24） %, P =0. 039] . The interaction of group with facial emotion intensity was significant （ F = 3.04, P = 0. 044）, and post hoc test found that the group difference was particularly significant on the middle intensity of happy and disgust facial emotion. Conclusion： Facial emotion recognition is impaired in patients with schizotypal personality disorder （ SPD）, wh
