A+ Treatment/Feasibility of Adapted ESDM-informed Caregiver Coaching Delivered Remotely for Children With ASD (Autism Spectrum Disorder) and ADHD (Attention Deficit Hyperactivity Disorder)

This study will evaluate the feasibility of adapted ESDM-informed caregiver coaching in children with comorbid ASD and ADHD, who are between 36 and \<132 months of age. There will be no study provided medication treatment in this study. Children will either be on ADHD medication prescribed by their own personal provider or will not be taking any ADHD medication (this will be documented by the study). The provided behavioral treatment will be eight \~60-minute sessions in ESDM-informed caregiver coaching delivered remotely through telehealth, for 8 consecutive weeks. The behavioral treatment is provided to children through Early Start Denver Model (ESDM)-informed caregiver coaching strategies, implemented within the child's typical daily routine by the caregiver.
