摘　　要：目的探究自杀意念大学生在注意偏向上是否存在情绪干扰。方法采用大学生人格问卷(UPI)和艾森克人格问卷(EPQ)相关题目结合结构式访谈对4 669名大学生进行筛查,抽取其中一部分有自杀意念大学生(自杀意念组,n=32)及正常大学生(对照组,n=32)使用情绪图词Stroop实验范式,考察有自杀意念大学生和正常大学生对情绪信息的注意偏向。结果 2组被试的反应时间比较差异有统计学意义(F=5.76,P<0.05)。自杀意念组大学生对情绪词语有更加突出的反应延迟特点(F=8.20,P<0.01);自杀意念组大学生在图词一致时反应时间与对照组比较差异无统计学意义(P>0.05),图词不一致时,反应时间显著长于对照组(t=3.70,P<0.01)。结论有自杀意念大学生与正常大学生相比,表现出了明显的情绪干扰,且具有更多的负性认知偏向。有自杀意念大学生在图词不一致的情况下有更多的反应延迟存在。Objective To explore whether college students with suicidal ideation have emotional interference in attentional bias. Methods A total of 4 669 college students were screened by the key questions of University Personality Inventory and Eysenck Personality Questionnai combined with structured interviews. The study employed emotional picture-word Stroop pattern to look into characteristics of attentional bias to emotional information in college students with suicidal ideation（ n = 32） and normal students（ n = 32） respectively. Results There was statistically significant difference in reaction time between college students with suicidal ideation and normal students（ F = 5. 76,P 0. 05）. College students with suicidal ideation had more obvious reaction delay than students without suicidal ideation on emotional words（ F = 8. 20,P 0. 01）; there was no statistically significant difference in reaction time of picture-word consistent task between college students with suicidal ideation and normal students,reaction time of college students with suicidal ideation was significantly higher than that of the normal students in picture-word inconsistent task（ t = 3. 70,P 0. 01）. Conclusion College students with suicidal ideation have emotional interference on their attentional bias; college students with suicidal ideation have much more negative cognitive bias than students without suicidal ideation and they have more reaction delay when the picture and word are inconsistent.
