telehealth parent-implemented intervention for young children with autism spectrum disorder (asd)

Conditions: Autism Spectrum Disorder

Summary: the primary objective of this research study is to improve outcomes involving core social-communication symptoms for young children with asd 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 asd.

the primary objective of this research study is to improve outcomes involving core social-communication symptoms for young children with asd 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 asd. the secondary hypothesis is that feasibility (defined as parent fidelity) of tc is non-inferior to ipc. an exploratory objective is to guide clinical decision-making for telehealth implementation by examining the heterogeneity of treatment response across the two treatment arms. the investigators will test the hypothesis that baseline child behavioral dysregulation, active engagement, developmental quotient, and parent stress moderate child social-communication outcomes. after completing eligibility testing, eligible children will be randomized into the tc or ipc condition. each condition will involve twice weekly coaching sessions over 12 weeks. at the end of the twelve weeks, participants will be reassessed.
