|Study Design:||Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Investigator, Outcomes Assessor)
Primary Purpose: Health Services Research
|Official Title:||Prolonged Exposure (PE) for PTSD: Telemedicine vs. In Person|
- 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 (PTSD and Depression); (2) Process (Treatment Satisfaction and Attrition); and (3) Economic (Cost) Outcomes. [ Time Frame: 6 months ]Per protocol treatment completers completed at least 6 90-minute sessions of Prolonged Exposure either In Person or via Telemedicine. Treatment dropout is defined as initiating treatment but completing fewer than 6 sessions. Per protocol, participants could have as many as 12 treatment sessions.
- PCL Scores at Pre and Post Treatment [ Time Frame: 6 months ]PTSD Checklist-Military (PCL-M): The PCL is a 17 Item Self Report Measure of PTSD Symptoms Based on the DSM-IV Criteria. The PCL uses a 5-point Likert scale response format ranging from not at all to frequently. Total scores on the PCL range from 17 to 85 (lower scores indicate less symptom severity). The instrument is highly correlated with the Clinician Administered PTSD Scale (r = .93), has good diagnostic efficiency (> .70), and robust psychometrics with a variety of trauma populations (Blanchard, 1996), including combat veterans (Magruder, Frueh, et al, 2005). The minimum score possible on this measure is 17, and the highest possible score is 85.
- BDI Scores at Pre and Post Treatment [ Time Frame: 6 months ]Beck Depression Inventory-II (BDI-II): (BDI; Beck et al., 1961): The BDI-II is a 21-item self-report scale, is among the most widely used instruments to measure depression. Beck and Steer (1984) demonstrated that the BDI-I has high internal consistency (α = .86 - .91). Lower scores indicate less symptom severity, and higher scores indicate more severe depressive symptoms. Raw scores of 0-13 indicates minimal depression; 14-19 indicates mild depression; 20-28 indicates moderate depression; 29-63 indicates severe depression. The lowest possible score on this measure is 0, and the highest possible score is 63.

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: The investigators 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. The investigators 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.
