Generalized anxiety disorder (GAD) is characterized by chronic worry that interrupts normal functioning. Some research has shown cognitive behavioral therapy (CBT) as an effective treatment for GAD, but only half of people treated with CBT for GAD experience treatment benefits long-term. Standard CBT for GAD may lose effectiveness over time because it does not address interpersonal and emotional processing problems. This study will determine the safety and feasibility of training therapists to deliver a version of CBT with additional therapeutic techniques for addressing interpersonal interactions and emotional processing.
