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.

Condition or disease Intervention/treatment Phase
Posttraumatic Stress Disorder Behavioral: Attentional bias retraining Not Applicable

Detailed Description:

Aim 1: Develop Attentional Bias Retraining protocol (Phase 1)

  • 1.1 Computerized assessment & retraining programs
  • 1.2 Procedures and measures

Aim 2: Implement in pilot sample (Phase 2)

  • 2.1: Assess feasibility and tolerability
  • 2.2: Collect pilot data to plan future studies
  • 2.3: Efficacy estimates based on changes in response time to dot probe task

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 22 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Masking Description: The transition point from the assessment only version of the attention bias program to the retraining/ bias correction version was randomized at the participant level and occurred between weeks 4 and 7 of the 10-week study.
Primary Purpose: Treatment
Official Title: Attentional Bias Retraining in Veterans
Study Start Date : May 2012
Actual Primary Completion Date : December 2012
Actual Study Completion Date : June 2015

Arm Intervention/treatment
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.
Behavioral: Attentional bias retraining
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.

Primary Outcome Measures :
  1. Post-traumatic Checklist - Military version (PCL-M) [ Time Frame: Change from Baseline and Post-treatment (1 month after last training session) ]
    PCL-M assess the 17-cardinal symptoms of PTSD.

Secondary Outcome Measures :
  1. Attentional bias scores [ Time Frame: Change from Baseline and Post-treatment (1 month after last training session) ]
    Attentional bias scores represent participants cognitive bias to orient towards trauma-relevant information more quickly than neutral information.

Other Outcome Measures:
  1. Daily of PTSD symptoms, specifically hyperarousal and intrusive symptoms (nightmares, reenactments, and triggered and untriggered recall) [ Time Frame: Change from Baseline and Post-treatment (1 month after last training session) ]
    Participants filled out daily symptom log nightly
