注意过程中的偏差被认为在社交焦虑障碍（SAD）的病因学和维持中起着至关重要的作用。本研究的目的是探讨一个旨在训练注意力朝向积极线索的方案和一个旨在训练注意力朝向消极线索的方案的有效性。在一项随机、对照、双盲设计中，将这两种训练条件对选择性注意力和社交焦虑的影响与对照训练条件进行了比较。使用修改后的点探测任务，并通过互联网提供。共有129名被诊断患有SAD的人被随机分配到这三种情况之一，并参加了为期14天的日常训练/控制课程。所有三组的参与者在训练前平均都没有表现出注意力偏差。重要的是，注意偏向变化的结果表明，在三种条件下，对威胁的选择性注意没有显著差异。然而，社交焦虑的症状显着减少，从前到后续评估在所有三个条件下（dwithin = 0.63-1.24），与程序旨在训练对威胁线索生产的注意，相对于控制条件，显着更大的减少社会恐惧。 在训练条件下，旨在诱导对积极线索的注意偏向和控制条件之间的社交焦虑结果没有显着差异。据我们所知，这是第一个随机对照试验，其中一个条件旨在诱导注意偏向负面线索产生更大的情绪效益比控制条件。有趣的是，症状的变化不太可能是由注意过程的变化机制引起的，因为偏见本身没有检测到变化。这一发现的影响，为今后的研究注意偏向修改社交焦虑进行了讨论。ClinicalTrials.gov NCT01463137
Biases in attention processes are thought to play a crucial role in the aetiology and maintenance of Social Anxiety Disorder (SAD). The goal of the present study was to examine the efficacy of a programme intended to train attention towards positive cues and a programme intended to train attention towards negative cues. In a randomised, controlled, double-blind design, the impact of these two training conditions on both selective attention and social anxiety were compared to that of a control training condition. A modified dot probe task was used, and delivered via the internet. A total of 129 individuals, diagnosed with SAD, were randomly assigned to one of these three conditions and took part in a 14-day programme with daily training/control sessions. Participants in all three groups did not on average display an attentional bias prior to the training. Critically, results on change in attention bias implied that significantly differential change in selective attention to threat was not detected in the three conditions. However, symptoms of social anxiety reduced significantly from pre- to follow-up-assessment in all three conditions (dwithin = 0.63–1.24), with the procedure intended to train attention towards threat cues producing, relative to the control condition, a significantly greater reduction of social fears. There were no significant differences in social anxiety outcome between the training condition intended to induce attentional bias towards positive cues and the control condition. To our knowledge, this is the first RCT where a condition intended to induce attention bias to negative cues yielded greater emotional benefits than a control condition. Intriguingly, changes in symptoms are unlikely to be by the mechanism of change in attention processes since there was no change detected in bias per se. Implications of this finding for future research on attention bias modification in social anxiety are discussed. ClinicalTrials.gov NCT01463137
