Cognitive Processing Therapy for Post-Traumatic Stress Disorder: A Systematic Review and Meta-Analysis

Last updated: August 11, 2015
Project Number: HT0009
Result type: Report

CADTH has undertaken a project on cognitive processing therapy (CPT) for adults who suffer from post-traumatic stress disorder (PTSD). PTSD is characterized by intrusive or distressing thoughts, nightmares, and flashbacks of past exposure to traumatic events such as the sudden death of a loved one, serious accidents, natural disasters, sexual or physical assault, child sexual or physical abuse, exposure to combat, and torture. CPT is a type of cognitive behavioural therapy that aims to provide a person who has PTSD with the skills to handle distressing thoughts and regain control of his or her life.

This systematic review addresses the effectiveness of CPT offered in an individual or group setting to alleviate the symptoms of PTSD, improve remission rates, and increase quality of life. In addition, this review will attempt to evaluate treatment compliance and completion rates, as well as contextual considerations such as health equity and access, patient preferences, implementation, and costs.
