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.
