The purpose of this project is to develop and pilot test a web-based enhancement of the classroom-based Advancing Social-Communication and Play (ASAP) intervention to support collaborations between home and school. ASAP was designed to develop joint attention (i.e., shared attention toward an object or event with another person) and symbolic play (i.e., pretending), both pivotal skills for young children with Autism Spectrum Disorders (ASD). Although there is evidence that ASAP is efficacious, there is little evidence of generalization across school and home contexts. Further, providing a greater connection between the two settings will help establish a more comprehensive assessment of the child's needs as part of ASAP. This new website, Promoting ASAP Collaboration through Technology (PACT), will be designed to generate individualized implementation recommendations based on child needs, and allow for electronic communication between school providers and parents who are implementing ASAP across school and home settings.
