The purpose of this project was to develop a grant proposal to fund a support program for adult siblings providing continuing care for their siblings with autism spectrum disorder (ASD) at The Arc of San Diego, San Diego, California. The proposed support program will include psycho-educational speakers, activities, and networking opportunities in a safe, culturally competent, and nonjudgmental setting. A review of literature was conducted to examine information on typically developing siblings having a sibling with ASD and the support needs for the typically developing sibling across the life span. The goal of the proposed program is to provide continued support to adult sibling caregivers who are providing care for their siblings diagnosed with ASD. This project required identification of a potential funding source and completion of a grant application to fund the program at The Arc of San Diego. Actual submission and funding of the grant application was not required for the successful completion of this project.
