Active Autistic Disorder

The primary objective of this research study is to improve outcomes involving core social-communication symptoms for young children with ASD or social communication delays by increasing access to clinically validated early behavioral intervention through a telehealth parent coaching model. The investigators will test the hypothesis that telehealth-delivered Naturalistic Developmental Behavioral Intervention parent coaching (TC) is non-inferior to in-person coaching (IPC) for the treatment of core social-communication symptoms in toddlers with either a social communication delay or ASD.
