This study analyzed National Institutes of Health ASD services research funding from 2008 to 2018 to examine funding patterns, evaluate the impact of IACC objectives, and identify future directions. Approximately 9% of total funds were allocated to services research. This investment remained relatively stable across time and lacked diversity across domains (e.g., area of focus, ages sampled, implementation strategies used). While advancements were observed, including increased prevalence of projects focused on adult samples and on dissemination/implementation and prevention areas, greater investment in service research is critically needed.Journal of autism and developmental disordersTrends Over a Decade in NIH Funding for Autism Spectrum Disorder Services Research.PMC8035332P50MH113662P50 MH113662Horwitz SMMatheis MCervantes PENelson KLHoagwood KESeag DEMEstabillo JPeth-Pierce RfalseTrends Over a Decade in NIH Funding for Autism Spectrum Disorder Services Research.Investments in autism spectrum disorder (ASD) research, guided by the Interagency Autism Coordinating Committee (IACC), have focused disproportionately on etiology over a well-established stakeholder priority area: research to improve accessibility and quality of community-based services.
