Metropolitan Atlanta Developmental Disabilities Surveillance Program
The two principal objectives of the Metropolitan Atlanta Developmental Disabilities Surveillance Program (MADDSP) are to (a) provide regular and systematic monitoring of prevalence rates of selected developmental disabilities according to various demographic characteristics of children and their mothers and (b) provide a framework for initiating special studies of children who have the selected developmental disabilities by establishing a population-based case series of such children. The case definition for inclusion in MADDSP is a child who: (a) is 8 years old any time during the study year of interest; (b) whose parent(s) or legal guardian(s) reside in the five-county metropolitan Atlanta area at some time during the study year of interest; and © who has one of more of the following disabilities: intellectual disability, cerebral palsy, hearing loss, vision loss, and/or autism spectrum disorder.
