Both naturalistic communication and parent-implemented interventions are evidence-based practices for young children with disabilities, but demonstrations of effective methods for teaching parents to implement naturalistic interventions successfully with their children are still warranted. The purpose of this study was to examine the effects of a training and coaching program on parent implementation of naturalistic teaching strategies and on concomitant child communication skills using a telepractice service-delivery model (i.e., Internet-Based Parent-Implemented Communication Strategies [i-PiCS]). We found that parents learned to implement the targeted naturalistic teaching strategies with fidelity when, and only when, they were provided with training and coaching over the Internet. The parents' implementation of these strategies also corresponded with positive changes in their children's communication skills. The limitations and implications of this investigation are discussed.
