This project will test a measure of treatment quality, Exposure Guide, for therapists using exposure therapy for youths and young adults with anxiety or OCD. We anticipate that users of this measure will be able to complete it reliably, find it acceptable, and that the measure will predict patient outcome. This project will include 40 therapists treating 300 anxious youth and young adults ages 5-21 at a large community mental health agency. Results of this study will establish the Exposure Guide as a measure of exposure quality in real world settings.
