The Center for the Treatment and Study of Anxiety (CTSA) is an internationally renowned research and clinical facility that offers state-of-the-art treatment programs specifically designed for Obsessive-Compulsive Disorder (OCD), Posttraumatic Stress Disorder (PTSD), Social Anxiety (SAD), Panic Disorder (PD), Agoraphobia, Generalized Anxiety Disorder (GAD), Specific Phobias, Trichotillomania, and Excoriation Disorder.

The Center was founded in 1979 by Edna B. Foa, Ph.D. We offer evidence-based treatment for children, adolescents, and adults in traditional outpatient (1-2x weekly) and intensive outpatient (daily treatment for 6 weeks) levels of care.

CTSA’s Intensive Outpatient Program (IOP) for OCD is a completely telehealth clinical service for adult patients with moderate to severe OCD in PA, NJ, and DE seeking a higher level of outpatient care delivered in a condensed timeframe. The IOP is a daily treatment program delivered in a fully virtual format that consists of approximately 4 hours per day of treatment 5 days per week for 6 weeks. Treatment includes daily individual sessions with a licensed psychologist, exposure therapy with an individual therapist, and group therapy.
