This study was conducted to first evaluate the effects caregivers’ fidelity of the Cool Versus Not Cool (CNC) intervention using remote behavioral skills training (BST) and second, to evaluate subsequent treatment effects when caregivers implement intervention with their child with ASD. The components of behavioral skills training used were instruction, modeling, role-playing, and feedback. Past research has not evaluated the effects of the CNC intervention on children with ASD’s social skills when implemented by their caregivers. Thus, this research was needed to evaluate the effectiveness of remote based BST and the effectiveness of caregiver-implemented CNC intervention. Results suggested that remote-based BST is a useful training strategy to train caregivers and to support caregiver-implemented CNC to improve children with ASD’s social skills. During follow up and generalization conditions across dyads, caregiver and child skills maintained. During generalization, caregiver skills maintained when teaching new social skills for Caregiver 1 and Caregiver 2, but not entirely for Caregiver 3. / Applied Behavioral Analysis
