Project Background/Rationale: Approximately 15 to 17% of current Iraq war veterans meet full
diagnostic criteria for MH problems such as post-traumatic stress disorder (PTSD) (Hoge et
al., 2004). Prolonged Exposure (PE) is an empirically supported treatment for PTSD (Foa
1997; Schnurr et al., 2007), and has been adopted by the Department of Veterans Affairs
(DOVA) as one of the treatments of choice for the disorder, as evident by the DOVA-sponsored
national training of clinicians to use PE. It is therefore important to employ treatment
delivery methods that maximize the likelihood that all veterans in need, including veterans
residing in rural settings, and veterans who avoid DOVA settings due to the stigma of
receiving mental health treatment, will receive interventions such as PE. The May, 2005
Committee on Veterans Affairs, Subcommittee on Health has identified Telemedicine as a DOVA
priority area to address this need. The present proposal is to study whether PE delivered
via Telemedicine is as effective as PE delivered In Person. Telemedicine has been chosen
for its ability to overcome what appear to be two major barriers to mental health care
(Frueh et al., 2000): the difficulty that rural-residing veterans face in reaching VAMC
facilities, and the stigma veterans perceive related to receiving mental health treatment.
Indeed, if effective, PE delivered via telemedicine may address the problem inherent in the
finding that 42% of those screening positive for PTSD indicate that they are interested in
receiving help, but only 25% actually receive services (Hoge, et al., 2006).
Project Objectives: Although effective treatments for PTSD exist and have been adopted by
the Veterans Affairs Medical Centers (VAMC), barriers to care of a social (e.g., stigma) and
geographic (e.g., rural) nature prevent many veterans in need from receiving care.
Telemedicine might address this need. The major objective of this study is to determine if
PE delivered via Telemedicine is as effective as In Person PE in terms of (1) clinical; (2)
process; and (3) economic outcomes.
Project Methods: We propose to use a randomized between groups repeated measures (baseline,
post-treatment, 3& 6-month followups) design with 226 OIF-OEF veterans diagnosed with PTSD
to assess the relative effectiveness, measured in terms of symptoms, patient satisfaction,
and costs, of PE delivered via Telemedicine vs. In Person formats. We hypothesize that no
differences (i.e., non-inferiority) between the two formats will be evident in terms
treatment gains, patient satisfaction, treatment attrition, patient satisfaction and direct
health care costs.
Anticipated Impacts on Veterans Health care: This study will provide important information
regarding whether PE delivered via home-based Telemedicine equipment is as effective as
traditional In Person delivery of PE for post-traumatic stress disorder. If shown to be as
effective as In Person treatment, a new, innovative, and cost effective intervention
delivery system for PTSD will have initial empirical support.
