NCT01564667

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Will Posttraumatic Stress Disorder and Symptom decrease with intervention

    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.

    8 weeks

Secondary Outcomes (1)

  • Other psychiatics symptoms (ie Depression, Anger, Anxiety)

    8 weeks

Study Arms (2)

Attention Bias Modification Treatment

EXPERIMENTAL

Attention bias modification training using a computerized spatial attention task (dot-probe) designed to alter threat-bias attention patterns away from threat.

Behavioral: Attention Bias Modification Training Protocol

Attentional Control Training

ACTIVE COMPARATOR

Attention control training using a computerized spatial attention taks (dot-probe) counter balances training toward and away from threat.

Behavioral: Attention Bias Modification Training Protocol

Interventions

Attention Bias Modification computerized training sessions administered 2 times per week for 4 weeks making a total of 8 training sessions.
