This book addresses behavior safety and clinical practice with persons who have intellectual and developmental disabilities (IDD). It focuses on safety concerns among children, youth, and adults with IDD who are susceptible to accidents and personal injury, lack self-preservation skills to prevent and avoid risk exposure, demonstrate behavior that is harmful (e.g., abuse, aggression, and property destruction), and receive restrictive and potentially unsafe interventions. The book examines characteristics of service settings, including strategies that promote environmental safety, training of care providers to implement safety protocols, and mitigation of risk factors associated with disease transmission. In addition, it describes evidence-based practices at the person-specific, intervention, and organizational levels, featuring service recommendations and directions for future research. Key areas of coverage include: Concepts and principles of behavior-based safety (BBS). Safety assessment and measurement. Prevention and risk-avoidance strategies. Safety skills training with children, youth, and adults. Environmental factors associated with personal safety. Clinical practice guidelines and evidence-based research support. Behavior Safety and Clinical Practice in Intellectual and Developmental Disabilities is an essential resource for professionals and practitioners as well as researchers, professors, and graduate students across such disciplines as developmental, clinical child, and school psychology, public health, social work, special education, applied behavior analysis, organizational behavior management, and all related psychology, education, and behavioral health fields.
