Cognitive Training to Address Functioning and Symptoms in Veterans With Posttraumatic Stress Disorder
VA Office of Research and Development
Summary
The proposed study will test a novel, computerized treatment for posttraumatic stress disorder (PTSD) to determine if it helps Veterans functionally recover as measured by reduced cognitive disability and PTSD symptoms. To do so, investigators will evaluate the effects of a cognitive training program that is designed to improve people's ability to manage information in working memory. Investigators will measure self-reported symptoms and disability alongside day-to-day cognition and functioning. The project support the VA Office of Research and Development's mission to improve Veteran participation in their lives and community by determining if this new approach can improve recovery from trauma and exploring for whom the intervention works.
Description
Posttraumatic stress disorder (PTSD) is a prevalent and debilitating condition among Veterans, associated with high healthcare utilization, physical comorbidities, and increased suicide risk. Despite the effectiveness of first-line psychotherapies for PTSD, these treatments do not universally address the neuropsychological deficits often seen in PTSD, such as impaired executive functioning, which contributes to both poor functional recovery and exacerbation of symptoms. There is a critical need for novel interventions targeting executive functioning to complement existing therapies and improve…

Interventions
- BehavioralCOGENT (Cognitive ENhancement Training)
COGENT is a computer-administered cognitive training program and consists of a modified working memory capacity task. COGENT was designed to contain high interference across trials, and requires participants to consistently, actively manage control over working memory interference. By requiring repeated practice with utilization of interference control across trials, COGENT is thought to enhance plasticity of cognitive systems used to manage how information enters and subsequently is removed from working memory, leading to improved performance over time.
- BehavioralST (Sham Training)
The sham training (ST) requires participants to remember the same total number of items as in COGENT; however, this training contains relatively less proactive interference across trials and is designed to be an "inert" version of the experimental program. The sham training condition will allow us to evaluate differences based on the proposed working memory interference training element, rather than general elements of the task (e.g., regular staff contact, contact time, general computer interface time).
