Feasibility, Safety, and Acceptability of Cognitive Processing Therapy for PTSD Following a Recent Suicide Attempt: A Case Study

Abstract

While cognitive processing therapy (CPT) has been found to be highly effective in the treatment of posttraumatic stress disorder (PTSD) and comorbid suicidal ideation, it is unknown how soon after a suicide attempt this treatment may be safe and effective. This case study investigates the effectiveness of weekly, telehealth-delivered CPT for a client with PTSD following a suicide attempt on the anniversary of a traumatic event. Results indicate a clinically meaningful reduction in PTSD symptoms and loss of PTSD diagnosis, as measured by the PTSD Checklist for DSM-5 (PCL-5), and a lack of further suicidal ideation or attempts. These results were maintained at long-term follow-ups at 1-, 3-, and 12-month periods. Qualitative data from the client further supported the effectiveness and acceptability of treatment. This case study suggests the potential of CPT as a valuable intervention for individuals with PTSD recovering from suicide attempts and highlights the importance of further research in this area. In support of this, the case study also suggests the use of nuanced suicide risk assessments, such as the fluid vulnerability theory (FVT), to respond to fluctuations in suicide risk in high-risk clients.
