Objective. Transdiagnostic models of psychopathology assume that the commonalities across disorders may outweigh their differences. While these models acknowledge that disorder-specific symptoms and features undoubtedly exist, the same underlying factors are perceived to cause and maintain various disorders. In recent years, this approach has received growing attention and several new forms of therapy have been developed based on it. These may be well-suited for the treatment of mixed-diagnosis groups or individuals with comorbid disorders, and as such, they hold the promise of being very cost-effective. One of the most established transdiagnostic treatments is the Unified Protocol (UP), designed to help patients suffering from depression and the full range of anxiety disorders. The purpose of the present study is to review the evidence regarding the efficacy and effectiveness of the UP for the transdiagnostic treatment of adult anxiety and depression. Methods. For this review, systematic literature searches were performed using the PsychInfo and PubMed online databases in October 2018. The search term used was “Unified Protocol”. The search yielded 114 results in PsychInfo and 138 in PubMed. Ten of these matched the following study selection criteria and were included in the current review: a) the study measured either the efficacy or effectiveness of the cognitive-behavioral UP therapy developed by Barlow (2011), b) treatment was delivered face-to-face in either individual or group setting, c) treatment followed the UP therapist guide without major modifications, d) participants suffered from an anxiety disorder or depression, e) participants were over 18 years of age, d) the study was published in 2015 or later, and f) the study was published in English in a peer-reviewed journal. Results and conclusions. The UP appeared both efficacious and efficient in reducing the severity of adult anxiety and depression as well as the number of comorbid diagnoses; however, there were some conflicting findings regarding recovery rates and effect sizes. The results achieved were comparable to those achieved using diagnosis-specific cognitive-behavioral therapy. The UP treatment had a positive impact on the patients’ functioning and quality of life and the amount of positive and negative affect they experienced. Treatment retention was generally high, particularly when treatment was delivered individually, and the UP received high ratings from those who participated in the studies. All in all, the current empiric evidence regarding the UP appears fairly promising. However, these results must be interpreted with caution, as the research concerning the UP is still in its infancy and a large part of it has been conducted by researchers affiliated with the treatment.
