Veterans with Posttraumatic Stress Disorder (PTSD) will be randomly assigned to either Attention Bias Modification Treatment (ABMT) designed to reduce bias toward threat or a placebo control condition not designed to change attention patterns. Outcome measures will be PTSD, anxiety, depression, and alexithymia symptoms as measured by standard psychological interviews and questionnaires. Participants will also be invited to participate in physiological testing before and after receiving AMBT or placebo to serve as additional outcome measures and assess brain functioning, heart rate, and muscle tension.

The investigators expect to see significant PTSD symptom reduction in the Attention Bias Modification Treatment (ABMT) group relative to the placebo control group in which no symptomatic relief is expected. At the end of the study, if ABMT is shown to be effective, we will offer active ABMT to those participants randomly assigned to the placebo arm if they would like to receive the treatment.

Further study details as provided by Creighton University:

Primary Outcome Measures:
  • Will Posttraumatic Stress Disorder and Symptom decrease with intervention [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    Using Clinician-Administered PTSD Scale (CAPS): The clinician-Administered PTSD Scale (CAPS) is a 30-item structured interview that corresponds to the DSM-IV criteria for PTSD (Blake, Weathers, Nagy, Kaloupek, Charney, & Keane, 1995) to assess symptoms of PTSD outcome.

Secondary Outcome Measures:
  • Other psychiatics symptoms (ie Depression, Anger, Anxiety) [ Time Frame: 8 weeks ] [ Designated as safety issue: No ]
    To assess potential decrease in psychiatric symptoms associated with PTSD, by comparing pre intervention and post intervention scores on psychological measures of deprssion, anger and anxiety.

Estimated Enrollment: 60
Study Start Date: April 2012
Estimated Study Completion Date: December 2014
Estimated Primary Completion Date: December 2014 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Attention Bias Modification Treatment
Attention training using a computerized spatial attention task (dot-probe) designed to alter threat-bias attention patterns.
Behavioral: Attention Bias Modification Training Protocol
Attention Bias Modification computerized training sessions administered 2 times per week for 4 weeks making a total of 8 training sessions.
Placebo Comparator: Placebo
This is a task designed to look like Attention Bias Modification Treatment but without the therapeutic manipulation.
