Optimizing Treatment Response in VA Specialized Intensive/Inpatient PTSD Programs

Not Applicable

Completed

• Conditions: PTSD
• Interventions: Behavioral: Group PE

• Registration Number: NCT03533608
• Lead Sponsor: VA Office of Research and Development

Brief Summary

Prolonged Exposure therapy (PE) is a first-line treatment for posttraumatic stress disorder; however few VA patients receive this treatment. One of the barriers to PE receipt is that this treatment is only available in an individual (one-on-one) format, whereas many VA mental health clinics provide the majority of their psychotherapy services in group format. In particular, PTSD residential rehabilitation programs (RRTPs) offer most programming in group format. Thus, the current study was designed to pilot test a group format of PE in RRTPs.

Detailed Description

Fifty Veterans who are currently receiving treatment in the PTSD RRTP at a Midwest VA will be recruited to participate in a Group PE protocol. Participants will engage in 12, 90-minute sessions of Group PE over the course of 6 weeks. Treatment consists of psychoeducation, rationale for treatment, and in vivo exposure to reduce trauma-related avoidance and thereby improve PTSD symptoms. PTSD symptoms will be measured via the PCL-5. The goal of this pilot study will be to determine whether or not it will be feasible to conduct a full-scale trial of Group PE in the current setting by testing the process, resources, management, and scientific basis of the planned trial. As such, the proposed study will primarily assess feasibility outcomes and not efficacy outcomes. The investigators will assess number of participants screened, number meeting inclusion criteria, adherence of participants to the proposed treatment (measured via number of sessions attended), standard deviation of the outcome measure (PCL-5), response rates to questionnaires, and loss to follow-up. The investigators will also measure clinicians' adherence to protocol and acceptability of the treatment to patients.

Arm && Interventions

Group	Intervention	Description
Group PE	Group PE	Participants will engage in twelve 90-minute sessions of Group PE over the course of 6 weeks. Treatment consists of psychoeducation, rationale for treatment, and in vivo exposure to reduce trauma-related avoidance and thereby improve PTSD symptoms.

Primary Outcome Measures

Name	Time	Method
Change in Depression Symptoms	Baseline, 6 weeks, 2-months	Depressive symptoms will be measured via the PHQ-9 at baseline, 6-weeks, and 2-months. The PHQ-9 is a 9-item self-report measure that assesses the presence and severity of depressive symptoms. Patients are asked to rate the presence of symptoms over the past 2 weeks on a 4-point likert scale ranging from 0-3 (not at all, several days, more than half the days, nearly every day). Individual items are summed together and Total scores ranging from 5-9 indicate mild depression, 10-14 indicate moderate depression, 15-19 indicate moderately severe depression, and 20-27 indicate severe depression. Change = (Week 6 score-Baseline score) and (2 month score-Baseline score).
Change in PTSD Symptoms	Baseline, 6-week, and 2-months	PTSD symptoms will be measured via the PCL-5 at baseline, 6-week, and 2-months. The PCL-5 is a 20-item self-report measure that assesses the presence and severity of PTSD symptoms. Patients are asked to rate how bothered they are by each item in the past month on a 5-point likert scale ranging from 0-4 (not at all, a little bit, moderately, quite a bit, extremely). Items are summed together and a PCL-5 cut point score of 33 is used for provisional PTSD diagnosis. Change = (Week 6 score-Baseline score) and (2 month score-Baseline score).
