Cognitive Training for Functioning in PTSD

2026年7月14日 更新者:VA Office of Research and Development

Cognitive Training to Address Functioning and Symptoms in Veterans With Posttraumatic Stress Disorder

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.

詳細な説明

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 outcomes. The investigator team has developed Cognitive ENhancement Training (COGENT), a low-burden, computer-based neurotherapeutic program designed to improve executive functioning. Preliminary data suggest COGENT may improve cognitive and affective symptoms in Veterans with PTSD, but larger, rigorous trials are needed to assess its clinical utility.

COGENT represents a promising innovation in PTSD treatment by focusing on enhancing executive functioning, which is directly implicated in the regulation of PTSD symptoms. Unlike existing therapies, COGENT targets cognitive deficits that drive symptom severity using a relatively brief, computer-administered format, offering a potential alternative pathway for improving recovery. If successful, this intervention could provide a scalable, cost-effective, and easily integrated treatment for Veterans with PTSD, improving their daily functioning and reducing symptom burden.

Specific Aims: 1) Evaluate the impact of COGENT on clinical functioning and PTSD symptoms. Investigators hypothesize that COGENT will lead to significant reductions in cognitive disability and re-experiencing symptoms relative to a control group. 2) Assess the real-world effects of COGENT on cognitive, emotional, and functional outcomes using smartphone-based ecological momentary assessments. Investigators hypothesize that COGENT will improve cognitive performance, reduce mood symptoms, and decrease functional impairment in everyday settings. Exploratory Aim) Identify predictors of treatment outcomes. This will explore how baseline cognitive performance and sociodemographic and clinical characteristics (e.g., traumatic brain injury history) influence the response to COGENT.

Successful outcomes from this will support the translation of COGENT into VA care. If effective, COGENT could be either provided as direct-to-Veteran services or integrated into routine clinical practice within the existing PTSD treatment programs as a cost-effective, widely accessible option for improving cognitive and clinical outcomes. Further research will explore potential for widespread dissemination and individual-level tailoring to optimize treatment benefits for Veterans with PTSD.

介入・治療
実験的:Cognitive ENhancement Training (COGENT)
Participants will be Veterans assigned to the active cognitive training program, Cognitive ENhancement Training (COGENT).
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.
偽コンパレータ:Sham Training (ST)
Participants will be Veterans assigned to the sham training comparator (ST), a non-training cognitive program matched for time and memory demands.
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).

結果測定
メジャーの説明
時間枠
Change in World Health Organization Disability Assessment Schedule (WHODAS 2.0), cognitive domain
時間枠:baseline, post (week 10), 3-month follow-up, 6-month follow-up
The WHODAS is a widely used, standardized tool designed to assess the level of disability experienced by individuals across various health conditions, including mental health disorders like PTSD. The WHODAS measures disability across six domains of functioning. The current project will utilize the cognition domain score to measure cognitive disability. A simple score for the WHODAS 2.0 ranges from 36-180 with higher scores indicating the degree of functional limitations.

メジャーの説明
時間枠
Baseline neuropsychological performance
時間枠:baseline, post (week 10)
A brief neuropsychological test battery will be used to predict response to the study intervention, based on evidence from previous work demonstrating that individuals with lower initial cognitive functioning may experience greater improvement in symptoms. The neuropsychological battery will consist of the Delis-Kaplan Executive Functioning System (DKEFS) Verbal Fluency, TestMyBrain (TMB) Trails, TMB Digit Symbol Matching and Choice Reaction Time, Wechsler Adult Intelligence Scale-IV (WAIS-IV) (Digit Span, Letter Number Sequencing), AX Continuous Performance Test from the Cognitive Neuroscience Test Reliability and Clinical applications for Schizophrenia (CNTRaCS) battery, and the California Verbal Learning Test-II (CVLT-II). The Montreal Cognitive Assessment (MoCA) screening will also be administered. All measures will be scored using published norms and a composite z-score by domain will be calculated, with higher scores indicating greater cognitive performance.

Global functioning (WHODAS 2.0)
時間枠:baseline, post (week 10), 3-month follow-up, 6-month follow-up
Change in global functional impairment related to social and life responsibilities will be measured by the WHODAS 2.0 (mobility, self-care, getting along, life activities, participation subscales) as part of measuring broad functional effects. A simple score for the WHODAS 2.0 ranges from 36-180 with higher scores indicating the degree of functional limitations.

Global functioning (IPF)
時間枠:baseline, post (week 10), 3-month follow-up, 6-month follow-up
Change in global functioning will be measured by the Inventory of Psychosocial Functioning (IPF), as part of measuring broad functional effects. The IPF measures PTSD-related impairment in social and life responsibilities, such as romantic and family relationships, work, friendships and socializing, parenting, education, and self-care. Items are scored on a 0 (never) to 6 (always) scale, with higher scores indicating greater functional impairment.

A composite score, Positive Activities for Cognitive Engagement (PACE), will be used to measure COGENT effects on day-to-day functioning. This composite score will be generated from results of ecological momentary assessment (EMA) surveys and ecological momentary cognitive testing (EMCT), which will be administered to participants via smartphone 3 times per day for the 7-day period directly after the baseline and post-treatment visits.
