Transdiagnostic Behavior Therapy (TBT) for Generalized Anxiety Disorder

Generalized anxiety disorder (GAD) is a highly prevalent disorder that has a number of overlapping symptoms with and is frequently comorbid with other affective disorders. Despite its prevalence, the evidence-based therapies (EBTs) for GAD have lagged behind the EBTs for the other affective disorders. The newly developed transdiagnostic psychotherapies may be well suited to the highly overlapping and comorbid presentations of GAD. The present case study involves a veteran with GAD receiving Transdiagnostic Behavior Therapy (TBT), a transdiagnostic behavioral intervention designed for veterans with affective disorders, but has yet to be investigated in GAD, a disorder with a significant cognitive component. The veteran case completed 8 sessions of TBT. Significant symptom improvements were evidenced at post-treatment assessment and sustained at follow-up. The present case study provides very preliminary evidence to suggest that transdiagnostic EBTs, such as TBT, may be a potentially effective treatment for GA
