Different manuals have been developed for evidence-based psychotherapies of mood and anxiety disorders. Barlow and colleagues studied a unified protocol for the transdiagnostic treatment in a randomized equivalence trial of 233 adult patients with various anxiety disorders. Reduction in symptom severity with the unified protocol was statistically equivalent to reductions with single-disorder protocols after 16 to 21 weeks of treatment and at the 6-month follow-up. In an Editorial, Roy-Byrne discusses the importance of the study for the dissemination of psychotherapy for anxiety disorders.
