Caregivers of young children who have or are at risk for disabilities may struggle supporting their child’s language development. This study used a tailored rapid coaching intervention to teach a caregiver different naturalistic language interventions that can be used with their child during play. Evidence-based naturalistic skills for increasing child communication were chosen to teach the caregiver based on baseline levels of skills. The purpose of this study was to evaluate the effectiveness of a tailored RCI (training and coaching) with caregivers of children with developmental disabilities. Like other studies, this study involved evaluating child-level communication but extended child measures by including as assessment of happiness behaviors. Child happiness behaviors were recorded and assessed across the study to evaluate the social validity of the caregiver coaching intervention. In addition, a speech-language pathologist collaborated with the research team to assist in selecting instructional language targets for the child.
