Telemedicine has the potential to profoundly influence the delivery of specialized care to the remote veteran population suffering with PTSD. Preliminary research supports telemedicine technology as a possible solution to improve access to mental health services for veterans with PTSD. The proposed research is a treatment-outcome study that will assess the clinical efficacy of conducting an Anger Management Therapy (AMT) group treatment intervention using a videoteleconferencing (VTC) modality as compared to the traditional in-person modality with veterans who have PTSD and reside in remote locations on the Hawaiian Islands. AMT is a manual-guided cognitive-behavioral, skill based group intervention that has been used nationwide in VA substance abuse programs and most recently has been adopted by many VA PTSD Clinical Teams to treat anger-related to the sequelae of PTSD.
