Efficacy of Adding Interpersonal and Emotional Processing Therapy Techniques to Cognitive Behavioral Therapy to Treat Generalized Anxiety Disorder

Generalized Anxiety Disorder Clinical Trial

Official title:
Cognitive and Interpersonal Therapies for Generalized Anxiety

Clinical Trial Summary

This study will test a version of cognitive behavioral therapy for generalized anxiety disorders that incorporates interpersonal and emotional processing techniques.

Clinical Trial Description

Generalized anxiety disorder (GAD) is characterized by chronic worry that interrupts normal functioning. Some research has shown cognitive behavioral therapy (CBT) to be 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 efficacy of a version of CBT with additional therapeutic techniques for addressing interpersonal interactions and emotional processing among adults with GAD. Participation in this study will include 14 weeks of treatment and 2 years of follow-up visits. All participants will receive 14 weekly, 2-hour, individual therapy sessions and one maintenance session scheduled after completing treatment. During the first hour of each session, all participants will receive standard CBT. Participants will be randomly assigned to receive one of two therapies during the second hour: training in interpersonal and emotional processing techniques or listening therapy. Participants may continue taking their current medications if they maintain a fixed dosage and keep a daily dairy of medication use, starting 2 weeks before study entry and lasting throughout treatment. In-depth study assessments will take place at baseline and after completing the 14 weeks of therapy. Assessments will include clinical interviews, self-report questionnaires, and a physiological measurement session. Questions will pertain to anxiety symptoms, self-perceptions, emotional experience, and perceptions of the world. The physiological measurement session will involve recording bodily reactions, including brain waves, heart rate, eye movement, and breathing, while performing simple perceptual tasks. Brief psychological assessments will also follow each therapy session. Follow-up assessments conducted 6, 12, and 24 months after completing treatment will involve interviews and questionnaires as well as recording a week's worth of medication diaries. ;
