青少年焦虑障碍患者的情绪记忆特点

The characteristics of emotional memory in adolescent with anxiety disorders

目的探讨青少年焦虑障碍患者情绪记忆的特点。方法选取40例符合DSM-5诊断标准的青少年焦虑障碍患者为焦虑障碍组和性别、年龄和受教育程度与之匹配的正常青少年40人作为正常对照组。对两组受试者进行情绪记忆试验任务测评。结果(1)情绪记忆测试中,青少年焦虑障碍组[(2.10±0.75)分]的负性图片评分显著小于正常对照组[(2.76±0.92)分](t=-3.29,P<0.05),而正性和中性图片评分均差异无统计学意义(P >0.05)。(2)青少年焦虑障碍组的正性(0.24±0.09)、中性图片再认正确率(0.22±0.10)和总再认正确率(0.25±0.08)均显著低于正常对照组[(0.33±0.08),(0.32±0.14),(0.33±0.09),t=-4.28,-4.28,-3.85,均P<0.05],负性图片的再认正确率差异无统计学意义(P >0.05);焦虑障碍组中负性与正性、中性图片再认正确率间存在差异有统计学意义(F=3.39,P<0.05);正常对照组中,三组图片的再认正确率差异无统计学意义(F=0.04,P >0.05)。(3)青少年焦虑障碍组正性图片再认正确率和总再认正确率与汉密尔顿焦虑评分呈负相关(r=-0.494,P<0.05)。结论青少年焦虑障碍患者存在情绪记忆缺损,且其正性情绪记忆缺损与焦虑严重程度呈负相关。

Objective To explore the characteristics of emotional memory in adolescent with anxiety disorders.Methods Totally 40 adolescent patients with anxiety disorders who met the DSM-5 diagnostic criteria were selected as the anxiety disorder group,40 normal adolescents matched with anxiety disorder group in terms of gender,age and education level served as the control group.All subjects of the two groups were implemented by emotional memory test task.Results(1)In emotional memory test,the negative picture score of adolescent anxiety disorder group(2.10±0.75)was significantly lower than that of control group(2.76±0.92)(t=-3.29,P<0.05).There were no significant difference in positive and neutral picture scores between the two groups(P >0.05).(2)Compared with control group,the positive picture,neutral picture and total recognition accuracy of adolescent anxiety disorder group both were significantly decreased((0.24±0.09)vs(0.33±0.08),(0.22±0.10)vs(0.32±0.14),(0.25±0.08)vs(0.33±0.09))(t=-4.28,-4.28,-3.85,all P<0.05).There was no significant difference in negative picture recognition accuracy between the two groups(P >0.05).In adolescent anxiety disorder group,there were significant differences in the correct recognition rates of negative pictures,positive pictures and neutral pictures in anxiety disorder group(F=3.39,P<0.05),while there was no significant difference in the control group(F=0.04,P >0.05).(3)The positive picture recognition accuracy and total recognition accuracy in adolescent anxiety disorder group were negatively correlated with Hamilton Anxiety Scale(HAMA)(F=0.04,P<0.05).Conclusion Adolescent anxiety disorders exist in emotional memory defects,and its positive emotional memory deficit is negatively correlated with the severity of anxiety.
