Continuity and security includes people with intellectual and developmental disabilities (IDD) not only having resources to meet their basic needs, but also includes the amount of change and disruption people have in their lives and the control they have over that change. We explored the impact of continuity and security on people with IDD's (n = 325) quality of life by analyzing Personal Outcome Measures interviews. Continuity and security not only significantly increased overall quality of life, but it also positively impacted two thirds of the different outcomes, ranging from health to relationships to rights. A stronger community infrastructure is needed to promote the continuity and security, and, by extension, quality of life of people with IDD.
