About The Study: In this cross-sectional study, U.S. adults with intellectual and developmental disabilities experienced substantially higher rates of mental health conditions, treatment use, and cost-related barriers compared with those without functional impairments. These findings highlight critical gaps for accessible, affordable, and disability-informed mental health services and policy reforms to address systemic inequities.
