Using acceptance and commitment therapy techniques to enhance treatment engagement in veterans with posttraumatic stress disorder

Evidence-based treatments for posttraumatic stress disorder (PTSD) are available for veterans, but many do not benefit due to low treatment engagement. This may be partially due to avoidance behaviors characteristic of individuals with PTSD. Acceptance and Commitment Therapy (ACT) is a transdiagnostic treatment approach that aims to reduce avoidance. The authors propose the use of adjunctive ACT techniques to enhance engagement with treatment for PTSD. ACT techniques such as cognitive defusion and values clarification have been shown to promote engagement with other cognitive-behavioral treatments, but no studies to date have examined these techniques as adjuncts to treatment for PTSD. Because of its focus on reducing avoidance, ACT is uniquely suited for promoting treatment engagement with the “gold standard” treatments for PTSD. The authors review the existing research on ACT as an adjunctive intervention, discuss specific concepts and techniques from ACT that are relevant to PTSD, and provide recommendations for future research.
