While attention modification programs (AMP) have shown promise as laboratory-based treatments for social anxiety disorder, trials of internet-delivered AMP have not yielded significant differences between active and control conditions. To address these inconsistencies, we examined the moderational and mediational role of attention bias in the efficacy of attention training. We compared data reported by Carlbring et al. (2012) to an identical AMP condition, with the exception that participants were instructed to activate social anxiety fears prior to each attention training session (AMP + FACT; n = 39). We also compared all attention training groups to an internet-delivered cognitive-behavioral therapy (iCBT) condition (n = 40). Participants in the AMP + FACT group experienced greater reductions in social anxiety symptoms than both active (n = 40) and control (n = 39) groups reported by Carlbring et al., and did not differ in symptom reductions from the iCBT group. Higher attention bias predicted greater symptom reductions for participants who completed AMP, but not for the control group. Moreover, change in attention bias mediated the relationship between AMP group (active condition reported by Carlbring et al. versus AMP + FACT) and change in social anxiety symptoms. These results suggest the importance of interpreting findings related to symptom change in attention training studies in the context of bias effects.

虽然注意力矫正程序（AMP）作为社交焦虑障碍的实验室治疗方法已显示出前景，但互联网提供的AMP试验在活性条件和对照条件之间并未产生显著差异。为了解决这些不一致的问题，我们研究了注意力偏差在注意力训练效果中的调节和中介作用。我们将卡尔布林等人（2012年）报告的数据与相同的AMP条件进行了比较，不同之处在于，参与者被指示在每次注意力训练课程之前激活社交焦虑恐惧（AMP + FACT；n = 39）。我们还将所有注意力训练组与互联网提供的认知行为疗法（iCBT）条件（n = 40）进行了比较。AMP + FACT组的参与者在社交焦虑症状方面的减轻程度比卡尔布林等人报告的活性组（n = 40）和对照组（n = 39）都更大，并且在症状减轻方面与iCBT组没有差异。较高的注意力偏差预测了完成AMP的参与者症状减轻程度更大，但对照组则不然。此外，注意力偏差的变化介导了AMP组（卡尔布林等人报告的活性条件与AMP + FACT）与社交焦虑症状变化之间的关系。这些结果表明，在偏差效应的背景下解释注意力训练研究中与症状变化相关的结果的重要性。
