Various reports in the national media have focused on a potentially significant rise in the incidence of autism during the past decade. As such, providing occupational therapy practitioners with a comprehensive guide for practice with people with an autism spectrum disorder (ASD) continues to be a primary goal of this best-seller. Recognizing that young children grow into adolescents and adolescents grow into adults, this updated edition includes additional content applicable to adults as well as incorporates the findings from the explosion of recent research in this area. Using the Occupational Therapy Practice Framework as a guide, the 24 revised and new chapters provide the information occupational therapy practitioners need to work with individuals with an ASD in client- centered and occupation-based practice.
