Shared Decision Making in PTSD Treatment

Summary

The purpose of this research study is to learn about how Shared Decision Making, when used to decide treatment, impacts treatment engagement, retention, and outcomes for active duty military personnel seeking treatment for posttraumatic stress disorder (PTSD). Shared Decision Making between the service member and the therapists will be used to match patients to 1 of 3 different types of therapy for PTSD: (1) Prolonged Exposure (PE) therapy, (2) Cognitive Processing Therapy (CPT), or (3) Written Exposure Therapy (WET) in 1 of 2 different frequencies: (1) massed (daily) or (2) spaced (weekly).

Detailed Description

The primary objectives of the project are to evaluate the relationships between patient characteristics, patient treatment preferences, treatment engagement, and treatment outcomes for active duty services members engaging in a Shared Decision Making pre-intervention followed by evidence-based PTSD treatment. A secondary objective is to evaluate the impact of Shared Decision Making to match patients to evidence-based cognitive behavioral treatments for PTSD. Aim 1: To conduct a partially randomized preference trial to examine the relationships between patient characteristics, treatment preferences, and treatment outcomes for active duty service members engaging in a Shared Decision Making pre-intervention followed by evidence-based treatment for PTSD. Research Question 1: What are the PTSD treatment initiation rates and completion rates for active duty service members engaging in a Shared Decision Making pre-intervention prior to starting an evidence-based treatment for PTSD? Research Question 2: Will patient characteristics (i.e., age, gender, military pay grade, racial-ethnic identity, deployment history) predict patient preference for a treatment type, session frequency, or treatment modality? Research Question 3: Will strength of preference in a specific treatment type, session frequency, or treatment modality predict PTSD treatment initiation, treatment completion, or PTSD symptom reduction? Aim 2: To evaluate the impact of Shared Decision Making on PTSD treatment completion and PTSD symptom reduction for active duty military personnel. Hypothesis 1: Patients who engage in Shared Decision Making will show higher rates of treatment completion as compared to prior PTSD randomized controlled trials (RCTs) with active duty service members Hypothesis 2: Patients who engage in Shared Decision Making will show larger reductions in PTSD symptoms from pre-to posttreatment as compared to benchmarked outcomes from prior PTSD RCTs with active duty service members. Treatment gains will be maintained over time, consistent with prior research.
