注意偏向矫正训练对青少年焦虑障碍的干预试验

An intervention trial of attentional bias modification training in adolescents with anxiety disorders

目的:探讨注意偏向矫正训练(ABMT)对青少年焦虑障碍的干预效果。方法:纳入符合ICD-10诊断标准青少年焦虑障碍患者60例,随机分为注意偏向矫正训练组(AB组,n=30)和无注意偏向矫正训练组(NAB组,n=30)。AB组予以连续10 d的注意偏向矫正训练,NAB组予以连续10d无注意偏向矫正训练。两组矫正前后,均采用注意偏向测定任务测评对负性刺激及中性刺激的注意偏向正确率及反应时及状态特质焦虑问卷(STAI)测评焦虑情绪的改变。结果:训练后,AB组注意偏向值的改变幅度大于NAB组[(16.3±8.2)ms vs.(-6.6±5.9)ms,P<0.05],AB组STAI中状态焦虑分降低幅度大于NAB组[(7.5±5.0)vs.(4.1±5.9),P<0.05]。结论:注意偏向矫正训练有效改善住院青少年焦虑障碍状态焦虑。

Objective:To investigate the effect of attention bias modification training(ABMT) in adolescents with anxiety disorders.Methods:Sixty adolescent patients with anxiety disorders meeting ICD-10 diagnostic criteria were included.They were randomly divided into the attentional bias modification training group(AB group, n=30) and the repeated exposure group(NAB group, n=30).The AB group received attention bias modification training for 10 consecutive days, while the NAB group received no attention bias modification training for 10 consecutive days.Before and after training, the attentional bias test was used to evaluate the accuracy and the response time of attentional bias for negative and neutral stimuli and State-Trait Anxiety Inventory(STAI) was used to evaluate the change of anxiety.Results:After training, the change amplitude of attention bias in AB group was greater than that in NAB group [(16.3±8.2) msvs.(-6.6±5.9) ms, P<0.05].And the reduction of state anxiety scores in STAI in AB group was greater than that in NAB group [(7.5±5.0) vs.(4.1±5.9),P<0.05].Conclusion:Attentional bias modification training could reduce the state anxiety of hospitalized adolescents with anxiety disorders more effectively.
