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.
