Study Characteristics

Objectives

  • The primary objective is to compare the effectiveness of Prolonged Exposure (PE) and Cognitive Processing Therapy (CPT) for reducing the severity of PTSD symptoms.
  • The secondary objective is to compare the effectiveness of PE and CPT for reducing the severity of comorbid mental health problems and service utilization and improving functioning and quality of life.
  • The tertiary objective is to examine whether discrepancy between patient preferences and treatment assignments reduces the effectiveness of each treatment.

Exploratory analyses will examine whether demographic and clinical characteristics predict differential response to PE and CPT.
