The purpose of this Small Business Innovation Research (SBIR) Phase I grant is to develop Educating Adults About Children With Autism Spectrum Disorders (EACA), an educational training program for school personnel who regularly interact with children in grades 1 through 5 with autism spectrum disorders (ASDs). EACA is an innovative multimedia training program specifically designed to meet the pressing need for educational resources for adults who interact with the growing numbers of children with ASDs entering the public education system. Customized sections for adults in public school settings, such as paraeducators (i.e., personal assistants/one-on-one aides), administrators, bus drivers, and librarians, will effectively engage and train these adults to positively interact with a child with autism, manage problem behaviors, and foster social inclusion in various school settings. Program components will include a training facilitator's guide, participant workbook, and audiovisual program supplement to be used during in-person staff trainings. At the end of the Phase I project, researchers will conduct a pilot study using a randomized experimental/lagged control design with paraeducators to determine acceptability and usability as well as to assess effectiveness in increasing participants' knowledge related to understanding ASDs and promoting positive attitudes toward children with ASDs.
