Impairments in social communication are widely recognized as one, if not, the core deficits in children with autism spectrum disorder (ASD). Many of the social communicative behaviors that contribute to sustaining reciprocal conversation are lacking in children with ASD. Specifically, impairments include ignoring or rejecting conversational bids, deficits in sustaining conversation and contingently responding to conversational partners. In addition, researchers have noted children with ASD's impairment in asking appropriate questions during social conversation. Consequently, the development of interventions that target social communication deficits in this population is of marked importance. Naturalistic behavioral interventions have shown promising results in ameliorating the social communicative deficits in children with autism. In addition to demonstrating rapid acquisition and spontaneous use of the target behavior, these types of intervention usually demonstrate generalization effects and meaningful outcomes. The purpose of this study was to examine whether intervention strategies incorporating motivational variables can improve the use of contingent queries. Furthermore, the study examined whether the improvements in contingent queries lead to improvements in conversational skills in children with autism. A nonconcurrent multiple baseline design across participants was employed to address the research question. The results indicated that the intervention led to (a) increased use of contingency queries in both environmental conversation and abstract conversation (b) increased synchronous discourse (c) increase in the diversity of responses and (d) increased turn taking during conversation. Furthermore, that data suggest both maintenance and generalization of treatment gains. Clinical and theoretical implications are discussed.
