Social-communication deficits associated with autism spectrum disorder often lead to undesirable outcomes in other domains, such as interpersonal relationships, employment, and participation in community activities. Parents may be ideal implementers of interventions to address these deficits when provided with instruction that is efficacious and feasible. This study evaluated a web-based group training and multimodal communication protocol of individualized parent coaching to improve parent implementation of communication intervention components. Results indicated a moderate functional relation between the parent-coaching intervention and parent implementation of the instructional behaviors. Implications and suggestions for future research are discussed.
