采用一种成熟的视觉探测任务，考察大样本焦虑障碍青少年对威胁面孔的注意偏向。研究参与者包括101名儿童和青少年（7- 18岁），他们患有广泛性焦虑症，社交恐惧症和/或分离焦虑症，参加了一项多部位焦虑治疗研究。分别招募了非焦虑青年（n = 51;年龄9 - 18岁）。参与者被管理的计算机视觉探测任务，呈现对面部描绘威胁（愤怒），积极（快乐）和中性的表情。他们按下一个响应键来指示探针的空间位置，该探针在每次试验中取代了其中一张脸。注意力偏差分数是根据对每种情绪面孔类型的探测的反应时间计算出来的。与健康的年轻人相比，焦虑的参与者对威胁面孔表现出更大的注意力偏见。焦虑症患者的这种威胁偏见在焦虑症患者中没有显着差异。对快乐面孔的注意偏向不存在组间差异。这些结果表明，儿童焦虑症与对威胁的注意偏向有关。未来的研究可能会检查焦虑青年的认知偏差随治疗而变化的方式。
To examine attention bias towards threat faces in a large sample of anxiety-disordered youths using a well-established visual probe task. Study participants included 101 children and adolescents (ages 7- 18 years) with generalized anxiety disorder, social phobia and/or separation anxiety disorder enrolled in a multi-site anxiety treatment study. Non-anxious youths (n = 51; ages 9 - 18 years) were recruited separately. Participants were administered a computerized visual probe task that presents pairs of faces portraying threat (angry), positive (happy) and neutral expressions. They pressed a response-key to indicate the spatial location of a probe that replaced one of the faces on each trial. Attention bias scores were calculated from response times to probes for each emotional face type. Compared to healthy youths, anxious participants demonstrated a greater attention bias towards threat faces. This threat bias in anxious patients did not significantly vary across the anxiety disorders. There was no group difference in attention bias towards happy faces. These results suggest that pediatric anxiety disorders are associated with an attention bias towards threat. Future research might examine the manner in which cognitive bias in anxious youth changes with treatment.
