Aggressive and destructive behaviors are an ongoing challenge for many children, adolescents, and adults with intellectual and developmental disabilities (I/DD). What's behind these high-risk behaviors, and how can professionals help manage them? Discover the answers in this comprehensive text, the most up-to-date compendium of knowledge on addressing challenging behaviors in the least restrictive settings using evidence-based, empirically supported practices.
