Product Description:
In their recent editorial, the editors of Autism, David Mandell and Luc Lecavalier (2014), question the validity of the Centers for Disease Control and Prevention (CDC) Autism and Developmental Disabilities Monitoring (ADDM) Networks estimates of the prevalence of autism spectrum disorder (ASD) in US communities. They argue that true prevalence studies must be based on direct, clinical examinations of individuals, rather than comprehensive reviews of clinical and educational records from multiple sources. They also argue that the continued increases in ASD prevalence over time as well as variations in prevalence among sites within the ADDM Network are evidence that the prevalence estimates must not be valid. Both of these arguments reveal a lack of understanding of the methods and purposes of public health surveillance, and a surprising lack of familiarity with previous studies of the epidemiology of developmental disabilities.
