Children with autism spectrum disorder (ASD) are often delayed in acquiring social initiation skills utilized during common early childhood activities. A multiple probe design was utilized to assess the efficacy of a shared book reading intervention to increase the independent commenting of three young children with ASD. The intervention resulted in participant's acquisition of social commenting in the form of independent pointing and verbal commenting to gain social attention from an adult. The results suggest that young children with ASD can independently initiate social interactions during shared book reading when these behaviors are systematically taught and reinforced. Implications for practice and directions for future research aimed toward generalization and improving the implementation of shared book reading interventions are discussed.
