Community integration is preferred by people with intellectual and developmental disabilities; community integration is also associated with positive outcomes. Yet, many people with intellectual and developmental disabilities, especially with higher support needs, remain isolated. This exploratory study examined the relationship between community integration, significant support needs, and emergency department utilization of people with intellectual and developmental disabilities (n = 251) by analyzing secondary Personal Outcome Measures® interview data. We found an interaction between community integration and comprehensive behavior support needs, wherein people with intellectual and developmental disabilities with comprehensive behavior support needs who participated in the life of the community had 78% fewer emergency department visits than those people with comprehensive behavior support needs who did not participate in the community. Not only is community integration preferred by people with intellectual and developmental disabilities, our research suggests it can also produce improved health outcomes for those with comprehensive behavior support needs.
