The use of practice assignments in cognitive processing therapy to promote cognitive and emotional change: A case study

Abstract

Cognitive processing therapy (CPT) is a first‐line treatment for posttraumatic stress disorder (PTSD). The primary goals of CPT are to identify and challenge dysfunctional cognitions resulting from the trauma to promote a more balanced set of beliefs and reduce manufactured emotions; encouraging expression of natural emotions further promotes symptom improvement. Between‐session assignments (homework) are an integral part of learning and practicing the skills developed during CPT, and these assignments are theorized to reinforce the proposed mechanisms of symptom change. This article begins with a brief description of the theoretical foundations of CPT and an overview of the session content of the CPT protocol, followed by a case study illustrating the use of CPT with the written account (CPT + A) with a survivor of childhood sexual assault. Although the client demonstrated some avoidance, her successful completion of practice assignments throughout treatment allowed her to identify and examine thoughts contributing to feelings of guilt and self‐blame as well as negative beliefs about the world. She was able to reduce her assimilated and overaccommodated stuck points to form a more balanced view of the trauma, and also process her natural emotions, resulting in a significant reduction of PTSD symptoms. The role of homework at each session and how the assignments addressed the proposed mechanisms of change in CPT are discussed, and recommendations to increase clients’ engagement in practice assignments in CPT are provided.
