Evaluation of cognitive restructuring for post-traumatic stress disorder in people with severe mental illness.

BACKGROUND: A cognitive-behavioural therapy (CBT) programme designed for post-traumatic stress disorder (PTSD) in people with severe mental illness, including breathing retraining, education and cognitive restructuring, was shown to be more effective than usual services. AIMS: To evaluate the incremental benefit of adding cognitive restructuring to the breathing retraining and education components of the CBT programme (trial registration: clinicaltrials.gov identifier: NCT00494650).
METHOD: In all, 201 people with severe mental illness and PTSD were randomised to 12- to 16-session CBT or a 3-session brief treatment programme (breathing retraining and education). The primary outcome was PTSD symptom severity. Secondary outcomes were PTSD diagnosis, other symptoms, functioning and quality of life.
RESULTS: There was greater improvement in PTSD symptoms and functioning in the CBT group than in the brief treatment group, with both groups improving on other outcomes and effects maintained 1-year post-treatment.
CONCLUSIONS: Cognitive restructuring has a significant impact beyond breathing retraining and education in the CBT programme, reducing PTSD symptoms and improving functioning in people with severe mental illness. © The Royal College of Psychiatrists 2015.
