青少年抑郁障碍病人注意偏向特点

目的探讨青少年抑郁障碍病人对情绪面孔图片的注意偏向特点。方法选取65例符合ICD-10诊断标准的青少年抑郁障碍病人为抑郁组，以性别、年龄和受教育程度与之匹配的正常青少年55人作为对照组。采用点探测范式，对受试者进行注意偏向任务测评。结果抑郁组在中性、负性图片注意反应时均高于对照组(P<0.01), 抑郁组注意偏向值大于对照组(P<0.01)，2组间注意反应准确率差异无统计学意义(P>0.05)。抑郁组中，负性注意反应时高于中性(P<0.05)，对照组内两者反应时差异无统计学意义(P>0.05)。HAMD量表评分与抑郁组中性和负性注意反应时呈正相关关系(r=0.315, r=0.413, P<0.01)。结论青少年抑郁障碍病人对负性情绪图片存在注意偏向效应。

Characteristics of attention bias in adolescents with major depression disorder

ObjectiveTo investigate the characteristics of attention bias for emotional face images in adolescents with major depression disorder.MethodsA total of 65 adolescents with major depression disorder who met the ICD-10 diagnostic criteria were recruited as the depresson group, and 55 healthy adolescents matched with depressive disorder group in terms of gender, age and education level were recruited as control group.The attention bias task was evaluated by point detection paradigm.ResultsThe attention response of neutral and negative images in depression group were both significantly higher than those in control group(P<0.01), and the attention bias value of depresson group was significantly higher than that of control group(P<0.01), but there was no statistical significance in the accuracy of attention response between the two groups(P>0.05).In depresson group, the negative attention response was significantly higher than neutral attention response(P<0.05), while there was no significant difference between the negative and neutral attention response in control group(P>0.05).HAMD scale score was positively correlated with neural and negative attention response in depresson group(r=0.315, r=0.413, P<0.01).ConclusionsAdolescents with major depression disorder have attention bias effect for negative emotional images.
