Youth PTSD Treatment (YPT) is a theory-based, 12-session, manual-driven protocol for individual treatment for 3-18 year-old children and adolescents. Youth PTSD Treatment has shown effectiveness in a trial of 7-18 year-old children. The preschool version, Preschool PTSD Treatment, has also shown effectiveness in a randomized trial of 3-6 year-old children. Both were developed by Mike Scheeringa, MD, MPH (in collaboration with Judy Cohen and Lisa Amaya-Jackson). This model shares many similarities with Trauma-Focused CBT, which many people may be familiar with, but differs in how anxiety management, exposure work, inclusion of parents, and very young children are approached.
