NCT02041572

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Post-traumatic Checklist - Military version (PCL-M)

    PCL-M assess the 17-cardinal symptoms of PTSD.

    Change from Baseline and Post-treatment (1 month after last training session)

Secondary Outcomes (1)

  • Attentional bias scores

    Change from Baseline and Post-treatment (1 month after last training session)

Other Outcomes (1)

  • Daily of PTSD symptoms, specifically hyperarousal and intrusive symptoms (nightmares, reenactments, and triggered and untriggered recall)

    Change from Baseline and Post-treatment (1 month after last training session)

Study Arms (1)

Attentional Bias Retraining

OTHER

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.

Behavioral: Attentional bias retraining

Interventions

Participants complete a computer-based intervention, which is designed to correct cognitive biases associated with PTSD by training to attend to neutral information rather than the trauma-related cue words.
