Social deficits are one of the defining symptoms of autism spectrum disorder and affect a child’s ability to build relationships with others. These deficits put children with autism at a disadvantage when most of their world is focused on building connections with others – family, friendships, and community ties. Sunny Starts, a service-learning project, was created to specifically meet the needs of families with young toddlers with autism. The primary focus of Sunny Starts is to enhance the quality of the parent-child relationship by teaching parents a basic teaching interaction and to arrange the child’s environment in ways that are mutually reinforcing. The purpose of this experiment is to study the effects of the Sunny Starts DANCE training package, a responsive parent training program, on three levels of parent and child behaviors: 1) teaching episodes, 2) turn taking, social attending, vocal requests, and 3) synchronous engagement. Participants included two parent-child dyads. Parent training included 5-minute video assessments, video review, descriptions, rationales, modeling, practice, and feedback. The effects of the parent training were evaluated using a concurrent multiple baseline across participants. Results indicate parent teaching episodes and child behaviors (turn taking, social attending, and verbal requests) increased during the intervention phase. The duration of parent-child synchronous engagement maintained at high levels and slightly increased.
