Abstract

Highlights: A novel cognitive training program (HIC) and control program (LIC) were tested. The HIC program improved cognition and re-experiencing symptoms, relative to the LIC program. Both groups showed reductions in general distress symptoms. Abstract: Post-traumatic stress disorder (PTSD) is a chronic and debilitating condition characterized by persistent intrusive memories. Although effective treatments exist for PTSD, there is a need for development of alternative treatments. Diminished ability to control proactive interference may contribute to re-experiencing symptoms and may be a novel intervention target. The present study tested an intervention designed to modify proactive interference control clinicaltrials.gov identifier: (NCT02139137 ). Forty-two women with PTSD were randomly assigned to a computerized cognitive training or a control condition. The impact of these programs on cognitive performance and symptoms was assessed. PTSD re-experiencing symptoms and interference control performance improved significantly more for individuals in the training group relative to those in the control group. Other PTSD and general distress symptoms improved equally over time in both groups. Cognitive training of this type may hold promise as a novel intervention for reducing PTSD symptoms, although the mechanism of action and implications for models of PTSD requires future study.
