Randomized Controlled Trial of the BraveBot Intervention as an Adjunctive Treatment for Young People With Anxiety and Related Disorders Receiving Outpatient, Exposure-Based Cognitive Behavioral Therapy

Summary

This study is testing a digital tool called BraveBot for young people who are receiving cognitive behavioral therapy (CBT) for anxiety, OCD, or related problems. BraveBot is a computer program, not a person. It talks with youth through their phone or computer while they do "face-your-fears"-style exposure therapy homework that their therapist has assigned. Sometimes an exposure is done with BraveBot's real-time coaching, and sometimes on their own; after each exposure, youth answer a few short questions about how it went. Rather than dividing participants into separate groups, the study randomizes each individual exposure homework assignment. Every time a young person opens an eligible exposure, the system makes a 1:1 random assignment deciding whether that exposure is completed with BraveBot's support or independently (self-guided). The main goal is to learn whether using BraveBot helps youth understand their exposure assignments better, put in more effort, stick with exposures when they are hard, feel more capable, and find exposures more helpful in "fighting back" against anxiety. The study also examines whether BraveBot increases the likelihood that assigned exposures are completed, and explores effects on anxiety symptoms and how safe, easy to use, and useful BraveBot feels for youth, their therapists, and parents. BraveBot does not replace the therapist, diagnose, or design exposures; it only supports the homework the clinician has assigned, and is used under clinician oversight. A built-in safety system can detect possible risk-related language, pause the session, show crisis resources (such as 988), and notify the treating clinician. The study is conducted within routine outpatient psychology clinics at Mass General Brigham. Up to 40 youth ages 12-22 will take part.
