The effectiveness of cognitive behavioral therapy with respect to psychological symptoms and recovering autobiographical memory in patients suffering from post-traumatic stress disorder

OBJECTIVES Given the persistence of post-traumatic stress disorder (PTSD) and its major impact on everyday life, it is important to identify effective treatments. In additional to pharmacological treatments, psychotherapeutic treatments are also highly effective. The aim of the present study was to investigate, among a sample of patients suffering from PTSD, the influence of an additional cognitive behavioral therapy (CBT) intervention on their symptoms of PTSD, depression, and anxiety, and on autobiographical memory. METHODS A total of 40 patients suffering from PTSD (mean age: 31.64 years; 78.6% female patients) and under psychopharmacological treatment were randomly assigned to an intervention or control condition. The intervention consisted of ten group sessions (one 60-90 minute session per week) of CBT. At baseline and 10 weeks later, a series of self-rating and experts'-rating questionnaires were completed. RESULTS Over time, symptoms of PTSD, depression, and anxiety decreased; however, greater improvement was observed in the experimental than the control condition. Likewise, as a general pattern of results, memory performance improved over time, though again this improvement was greater in the experimental condition. CONCLUSION Compared to a control condition, additional CBT improves the treatment of PTSD, with respect to both symptoms and autobiographical memory.
