分离(转换)性障碍男性新兵对情绪面孔注意偏向的研究

Research on attention bias of emotional faces in male recruiters with dissociative(conversion)disorder

目的了解分离(转换)性障碍男性新兵对情绪面孔的注意偏向及发生阶段。方法选择2018年9-12月贵港市某精神病专科医院诊断的分离(转换)性障碍男性新兵(患者组)和2018年9月入伍的健康男性新兵(对照组)作为分析对象,采用个体匹配对照分析,以线索-靶子范式探究分离(转换)性障碍男性新兵是否存在对负性情绪面孔的注意偏向及注意偏向的发生阶段。结果患者组与对照组对正性、中性和负性情绪面孔的提示效应得分与0的差异均有统计学意义(均P<0.01);患者组与对照组对正性、中性和负性情绪面孔的反应时长差异无统计学意义(P>0.05);患者组总体平均反应时长为(420.17±98.74)ms,对照组为(395.22±87.97)ms,两组差异有统计学意义(t=2.22,P<0.05);患者组对负性情绪面孔的警觉得分与0的差异有统计学意义(t=2.91,P<0.05),维持得分与0的差异无统计学意义(P>0.05),对正性情绪面孔的警觉得分与维持得分与0的差异均无统计学意义(均P>0.05);对照组对正性、负性情绪面孔的警觉得分、维持得分与0的差异均无统计学意义(均P>0.05)。结论分离(转换)性障碍男性新兵平均反应时间较长,表现出对负性情绪面孔的注意偏向的特征,且这种注意偏向发生在注意警觉阶段。

Objective To explore the attention bias of emotional faces and occurrence stages in male recruits with dissociative(conversion)disorder.Methods Male recruits with dissociative(conversion)disorder diagnosed in a psychiatric hospital in Guigang City from September to December 2018(patient group)and healthy male recruits enrolled in the army in September 2018(control group)were selected as research subjects.Individual matching control study was used to explore whether male recruits with dissociative(conversion)disorder had attention bias to negative emotional faces and the occurrence stage of attention bias with clue-target paradigm.Results There were significant differences in the prompting effect score and 0 of positive,neutral and negative emotional faces between patient group and control group(all P<0.01).There were no significant differences in the response time of positive,neutral and negative emotional faces between patient group and control group(P>0.05).The overall average response time of the patient group[(420.17±98.74)ms]was longer than that of the control group[(395.22±87.97)ms],and difference was statistically significant between the two groups(t=2.22,P<0.05).In the patient group,there was a significant difference between the alert score of negative emotional faces and 0(t=2.91,P<0.05),there was no significant difference between the maintenance score and 0(P>0.05),and there were no significant differences between the alert score and the maintenance score of positive emotional faces and 0(both P>0.05).In the control group,there were no significant differences between the alert score and the maintenance score of positive and negative emotional faces and 0(all P>0.05).Conclusion The average response time of male recruits with dissociative(conversion)disorder is long,showing the characteristics of attention bias to negative emotional faces,and this attention bias occurs in the stage of attention alertness.
