Radical Openness for Adolescents Pilot

Eligible patient (n=30) and healthy (n=30) adolescents and young adults will attend a baseline session where they will undergo an ERP neural assessment and fill out questionnaires. 8 patient participants interested in participating in a 4 month free RO DBT therapy trial will participate in weekly individual and skills class sessions. At the end of this 4 months, they will complete a second follow-up session where they will undergo an event related potential (ERP) neural assessment and fill out questionnaires. 8 of the remaining 30 patient participants who do not want to complete the free therapy trial will have the option to return for a second follow-up session where they will undergo an ERP neural assessment and fill out questionnaires while undergoing treatment as usual (outside of therapy trial).
