The Cognitive Behavioral Intervention for Trauma in Schools (CBITS) program is a school-based, group and individual intervention. It is designed to reduce symptoms of post-traumatic stress disorder (PTSD), depression, and behavioral problems, and to improve functioning, grades and attendance, peer and parent support, and coping skills. In this 2-day workshop, participants will receive an overview of the mental, health and academic consequences of childhood trauma and PTSD, an introduction to the history and evidence base of CBITS, thorough session by session demonstrations and supervised practice of each core concept for both group and individual sessions, and guidance on implementation and site planning. Following the workshop, each cohort will be invited to participate in phone-based clinical coaching support to enhance their competency and problem-solve barriers to implementation of CBITS.
