Computerized cognitive bias modification for social anxiety disorder has in several well conducted trials shown great promise with as many as 72% no longer fulfilling diagnostic criteria after a 4 week training program. To test if the same program can be transferred from a clinical setting to an internet delivered home based treatment the authors conducted a randomized, double-blind placebo-controlled trial.
After a diagnostic interview 79 participants were randomized to one of two attention training programs using a probe detection task. In the active condition the participant was trained to direct attention away from threat, whereas in the placebo condition the probe appeared with equal frequency in the position of the threatening and neutral faces.
Results were analyzed on an intention-to-treat basis, including all randomized participants. Immediate and 4-month follow-up results revealed a significant time effect on all measured dimensions (social anxiety scales, general anxiety and depression levels, quality of life). However, there were no time x group interactions. The lack of differences in the two groups was also mirrored by the infinitesimal between group effect size both at post test and at 4-month follow-up.
We conclude that computerized attention bias modification may need to be altered before dissemination for the Internet.

在几项精心设计的试验中，计算机化认知偏差矫正治疗社交焦虑症显示出了巨大的潜力，多达 72%的患者在为期 4 周的训练计划后不再符合诊断标准。为了检验是否可以将相同的程序从临床环境转移到基于互联网的家庭治疗，作者进行了一项随机、双盲、安慰剂对照试验。
在经过诊断访谈后，79 名参与者被随机分配到两个注意训练程序中的一个，使用探针检测任务。在主动条件下，参与者被训练将注意力从威胁上转移开，而在安慰剂条件下，探针以相同的频率出现在威胁和中性面孔的位置上。
对所有随机参与者进行意向治疗分析。即时和 4 个月随访结果显示，所有测量维度（社交焦虑量表、一般焦虑和抑郁水平、生活质量）均有显著的时间效应。然而，没有时间与组间的交互作用。在两个组之间也没有差异，这反映在测试后和 4 个月随访时的组间效应大小都非常小。
我们得出结论，计算机化的注意偏差矫正可能需要在互联网传播之前进行修改。
