- What is the clinical effectiveness of group cognitive processing therapy for adults with post-traumatic stress disorder, anxiety disorders, or mood disorders?
- What are the evidence-based guidelines associated with the group cognitive processing therapy for adults with post-traumatic stress disorder, anxiety disorders, or mood disorders?
Evidence from one systematic review, two randomized controlled trials and two non-randomized controlled trials suggested that compared with other group therapies, group cognitive processing therapy had a similar effect in improving clinical symptoms (post-traumatic stress disorder- or depression-related, and sleep disorders) in adult patients with post-traumatic stress disorder. Patients treated with individual cognitive processing therapy had greater improvements in post-traumatic stress disorder severity than group cognitive processing therapy. However, the clinical effectiveness of group cognitive processing therapy relative to other treatments for post-traumatic stress disorder should be interpreted with caution, due to the compromised quality and the small sample size in the majority of the included trials.One evidence-based clinical practice guideline developed in Australia suggests that group cognitive behavioral therapy may be provided as adjunctive to, but not be considered an alternative to, individual trauma-focused therapy.
