Transdiagnostic CBT. Recent research18 suggests that mood and anxiety disorders may have more commonalities than differences in underlying biological and psychological traits. Because the symptoms of anxiety and depressive disorders tend to overlap, and their rate of comorbidity may be as high as 55%,23 so-called transdiagnostic treatments have been developed. Transdiagnostic treatments target impairing symptoms that cut across different diagnoses. For example, patients with depression, anxiety, or substance abuse might share a common difficulty with regulating and coping with negative emotions.
In a preliminary comparison trial,24 46 patients with social anxiety disorder, panic disorder, or GAD were randomly assigned to transdiagnostic CBT (n = 23) or diagnosis-specific CBT (n = 23). Treatments were based on widely used manuals and offered in 2-hour group sessions across 12 weeks. Transdiagnostic CBT was found to be as effective as specific CBT protocols in terms of symptom improvement. Participants attended an average of 8.46 sessions, with similar attendance in each protocol. Fourteen participants (30%) discontinued treatment, similar to attrition rates reported in other trials of transdiagnostic and diagnosis-specific CBT.
Transdiagnostic treatments may facilitate the dissemination of empirically supported treatments because therapists would not be required to have training and supervision to competency in delivering multiple manuals for specific anxiety disorders. This could be attractive to busy practitioners with limited time to learn new treatments.
Bottom Line Efficacy of cognitive-behavioral therapy (CBT) for depression and anxiety is well established. Although no specific technique defines CBT, a common practice is to educate an individual about interrelationships between behaviors/activities, thoughts, and mood. CBT techniques can be customized to treat specific anxiety disorders, such as panic disorder, obsessive-compulsive disorder, and generalized anxiety disorder.
