The purpose of this research is to assess a stepped care model of a telehealth parenting program for children ages 2-6 years old with a neurodevelopmental diagnosis and behavior problems. Families will complete an online intake assessment, 6 group-based tele-health Parent-Child Interaction Therapy (PCIT) sessions, and an online post intervention assessment. Some families may receive additional individual virtual booster sessions and will complete a second online post assessment.
