This authoritative handbook reviews the breadth of current knowledge about developmental disabilities: neuroscientific and genetic foundations; the impact on health, learning, and behavior; and effective educational and clinical practices. Leading authorities analyze what works in intervening with diverse children and families, from infancy through the school years and the transition to adulthood. Chapters present established and emerging approaches to promoting communication and language abilities, academic skills, positive social relationships, and vocational and independent living skills. Current practices in positive behavior support are discussed, as are strategies for supporting family adaptation and resilience. "This well-written and comprehensive handbook is the most thorough and up-to-date volume available on evidence-based practice, research, and policy issues related to developmental disabilities. Written by the most knowledgeable leaders in the field, each chapter will serve as an invaluable reference on critical issues that cut across the disciplines of education, health care, and social services. The Handbook is essential reading for anyone who cares about making current knowledge a prelude to a bright future for people with developmental disabilities and their families." -Michael L. Hardman, PhD, Department of Teaching and Learning and Department of Special Education, University of Utah
