Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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).

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

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.

Group Type OTHER

Intensive Outpatient Program - Prolonged Exposure

Intervention Type BEHAVIORAL

Prolonged Exposure for Posttraumatic Stress Disorder (PE for PTSD; Foa, Hembree, \& Rothbaum, 2007) is an empirically supported behavioral therapy that utilizes exposure-based interventions to target the psychological mechanisms (i.e., avoidance; maladaptive cognitive changes) thought to maintain trauma-related symptoms. IOP-PE includes 15 days of PE treatment delivered over three consecutive weeks. The standard outpatient PE protocol has modified with seven treatment augmentations to meet the unique needs of post-9/11 veterans.

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

1. Active duty military service members or veterans (18 years or older) who were impacted by Hurricane Harvey.
2. Significant PTSD symptoms as measured by a Posttraumatic Stress Disorder Checklist (PCL-5) score of 34 or higher.
3. Able to speak and read English (due to standardization of outcome measures)
4. Able to participate in a three-week intensive outpatient program

Exclusion Criteria

1. 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)
2. Current and severe alcohol use warranting immediate intervention based on clinical judgment.
3. Evidence of a moderate or severe traumatic brain injury (as determined by the inability to comprehend the baseline screening questionnaires)
4. 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.
5. Other psychiatric disorders severe enough to warrant designation as the primary disorder as determined by clinician judgment
