简要总结
The study has two goals. First to develop a computer-based intervention meant to alter cognitive biases that contribute to ongoing PTSD symptoms. Second, we sought to pilot test the intervention in a small sample of veterans for feasibility and acceptability.

研究组 & 干预措施
Attentional Bias Retraining
Each participant receives 12 sessions. The first three sessions are baseline (assessment only) sessions. The last four sessions must be treatment sessions. The attentional bias intervention starts randomly on sessions 4 - 8, and continues until the end of the 12 sessions.
干预措施: Attentional bias retraining (Behavioral)
结局指标
主要结局

时间窗: Change from Baseline and Post-treatment (1 month after last training session)
PCL-M assess the 17-cardinal symptoms of PTSD.
次要结局
- Attentional bias scores(Change from Baseline and Post-treatment (1 month after last training session))
