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.

Participation is a central aspect of human functioning and a key focus of research and practice in the intellectual disability field. However, there is not an accepted definition of participation that guides research and practice. To inform the development of a definition, a scoping review of the intellectual disability literature from 2001-2015 was conducted. Findings suggest that existing research rarely uses definitions of participation, but does examine participation across multiple domains and addresses issues of access and inclusion. Less focus was placed on individual aspects of participation such as meaning, responsibility, and choice. Based on the findings, implications for future research and practice are provided.
