Predicting Treatment Outcomes With Intensive Outpatient Treatment for PTSD
The open-label clinical study explores potential modifiable predictors of treatment outcomes in a sample of 55 military service members and veterans with clinically significant PTSD symptoms who receive Intensive Outpatient Prolonged Exposure (IOP-PE).
- Posttraumatic Stress Disorder
- Eligible Ages
- Between 18 Years and 70 Years
- Eligible Genders
- Accepts Healthy Volunteers
- Active duty military service members or veterans (18 years or older) who were impacted by Hurricane Harvey.
- Significant PTSD symptoms as measured by a Posttraumatic Stress Disorder Checklist (PCL-5) score of 34 or higher.
- Able to speak and read English (due to standardization of outcome measures)
- Able to participate in a three-week intensive outpatient program
- Current manic episode or psychotic symptoms requiring immediate stabilization or hospitalization (as determined by the bipolar and psychosis modules of the Mini International Neuropsychiatric Interview (MINI) and clinical judgment)
- Current and severe alcohol use warranting immediate intervention based on clinical judgment.
- Evidence of a moderate or severe traumatic brain injury (as determined by the inability to comprehend the baseline screening questionnaires)
- Current suicidal ideation severe enough to warrant immediate attention (as determined by the Depressive Symptoms Index - Suicidality Subscale and the Self-Injurious Thoughts and Behaviors Interview short form) and corroborated by a clinical risk assessment by a credentialed provider.
- Other psychiatric disorders severe enough to warrant designation as the primary disorder as determined by clinician judgment
- Study Type
- Intervention Model
- Single Group Assignment
- Intervention Model Description
- This is a prospective, one-group, exploratory clinical study.
- Primary Purpose
- None (Open Label)
Intensive Outpatient Program - Prolonged Exposure
|Participants will complete fifteen weekday 90-minute Prolonged Exposure therapy sessions over three consecutive weeks plus seven augmentations designed to maximize treatment outcomes. If necessary, the treatment window may be extended for another week.||

Intensive Outpatient Prolonged Exposure (IOP-PE) is a three-week, intensive, individualized program that combines massed Prolonged Exposure with military-relevant treatment augmentations to treat posttraumatic stress disorder (PTSD; Peterson et al., 2018). Recent findings indicate that IOP-PE significantly decreased combat-related PTSD in post-9/11 service members and veterans (Peterson et al., 2019). However, IOP-PE is costly and requires a considerable commitment from the patient. Being able to prospectively identify which patients benefit most from IOP-PE will help treatment providers and patients make well-informed decisions about clinical care. The primary aim of this prospective, exploratory clinical study is to investigate potential predictors of treatment outcome following 15 sessions of IOP-PE delivered over 3-weeks in a sample of 55 military service members and veterans (i.e., individuals who have retired or separated from the US Armed forces, active duty personnel, reservists, and National Guardsmen/women) with significant PTSD symptoms. A follow-up assessment will be conducted one-month following the completion of treatment.
Predictor variables will include the following:
Aim 1: The PTSD Beliefs Inventory, the Dispositional Resilience and Disability Inventory, and the Credibility/ Expectancy Questionnaire.
Aim 2: The Disability-Recovery Implicit Association Test.
Aim 3: The Treatment Motivation Questionnaire and Service Connection Status
Aim 4: The Insomnia Severity Index, the Dimension of Anger Reactions-5, Patient Health Questionnaire-9, the Quick Drinking Screen, and the Pain Intensity, Enjoyment, and General Activity (PEG) Scale.
