简要总结
Attentional bias has primarily been investigated as a primary cognitive etiology of social anxiety symptoms. Previous research has found that individuals with high social anxiety showed facilitated attentional engagement to threat stimuli or delayed disengagement of attention from threat. Attentional Bias Modification Training (ABMT) was developed through applying the attentional mechanism in social anxiety. During ABMT, participants are deliberately induced to shift their attention away from threat stimuli and toward neutral stimuli. Despite its proven effectiveness, a recent meta-study found that the effect size of ABMT is significant but too small. As a result, the current study focuses on improving the existing ABMT by incorporating integrative factors into attention training. The current study aims to integrate bottom-up and top-down cognitive processes in ABMT. Participants will be randomly assigned to one of two conditions (active or placebo training) and will complete the ABMT for three weeks. The ABMT's efficacy will be assessed by comparing pre- and post-training measures.
详细描述
Individuals with at least mild level of social anxiety symptoms will be invited to the current study. Participants will be randomly assigned to one of the two attention training conditions: a Integrated Attentional Bias Modification (I-ABM) training or placebo training (PLT). Before and after the training, participants will complete computerized tasks (e.g., attention network task, dot-probe task) and self-report questionnaires.
The basic design of I-ABM training will follow the dot-probe task, which will ask participants to swipe or tap on the probe in the correct direction. The I-ABM training aims to shift attention away from threatening stimuli or improve the inhibitory control ability. The PLT training will have the same basic design, but this will not include therapeutic components. Participants will complete the training three times per week for three weeks (a total of 9 training sessions), and there will be post-training and a 2-week follow-up assessment.

研究组 & 干预措施
Integrated ABM (I-ABM)
The I-ABM will include four progressively difficult levels of training blocks, each containing 72 trials. Participants will be required to tap or swipe the probe in the correct direction during the first and second levels of training. The inhibitory control components will be included in the third and fourth levels, where participants should not respond to the probe under certain conditions. Each training will take 10-15 minutes, and participants will complete the sessions three times a week for three weeks.
干预措施: Attentional Bias Modification Training (ABMT) (Other)
Placebo Training (PLT)
The PLT has four training blocks that follow the same basic design as the I-ABM training. However, the PLT will not aim to change social anxiety-related attention bias. Participants will simply swipe or tap the probe regardless of the stimuli condition, which is expected to exert a minimum level of effect on changing the attention bias linked to social anxiety. Participants will complete the training three times per week for three weeks.
干预措施: General Attention Control Training (Other)
结局指标
主要结局
Change in Mini-Social Phobia Inventory (Mini-SPIN) across Pre-training, Post-training, and 2-week follow up
时间窗: Pre-training (before the first mobile training), Post-training (after three weeks of training), 2-Week follow-up (two weeks after the post training assessment)
The Mini-Social Phobia Inventory (Mini-SPIN; Connor et al., 2001) is a 3-item measure which assesses the degree to which an individual experiences fear or avoidance in social situations. The measure uses a 5-point-Likert rating scale ranges from 0="not at all" to 4="extremely", with a total score range of 0-12. At a cutoff score of 6, the Mini-SPIN showed sensitivity of 89% and specificity of 90% for detecting generalized social anxiety disorder (Connor et al., 2001). The higher the scores, the more severe the symptoms of social anxiety.
次要结局
- Change in Depression, Anxiety, and Stress Scale (DASS-21) across Pre-training, Post-training, and 2-week follow-up(Pre-training (before the first mobile training), Post-training (after three weeks of training), 2-Week follow-up (two weeks after the post training assessment))
- Change in Liebowitz Social Anxiety Scale (LSAS-SR) across Pre-training, Post-training, and 2-week follow-up(Pre-training (before the first mobile training), Post-training (after three weeks of training), 2-Week follow-up (two weeks after the post training assessment))
