The proposed study will address the specific objectives of the National Pain Management Strategy by helping to assure that clinicians practicing in the VA healthcare system are adequately prepared to assess and manage chronic pain effectively, especially when comorbid with PTSD. Knowledge gained from the proposed study could potentially be utilized by psychologists and other healthcare providers across the VA system nationwide who are currently engaged in Cognitive Behavioral Therapy treatment programs for chronic pain and PTSD. Given that Cognitive Behavioral Therapy has been shown to be efficacious for pain and PTSD, but not for comorbid pain and PTSD, it is imperative that a new integrated treatment be evaluated that has the potential to address the unmet needs of this large population. Thus, this study will have important implications for the delivery of pain management services to veterans and others with chronic pain and PTSD.
