Addressing the major advances in biomedical, psychological, social, and environmental sciences over the past decade, Developmental-Behavioral Pediatrics, 5th Edition, remains the reference of choice for professionals in a wide range of fields, including medicine and health care, education, social service, advocacy, and public policy. This foundational, pioneering resource emphasizes children’s assets and liabilities, not just categorical labels. Comprehensive in scope, it offers information and guidance on normal development and behavior, psychosocial, and biologic influences on development, developmental disorders, neurodevelopmental disabilities, and mental health conditions. It also discusses tools and strategies for diagnosis and management, including new assessments that can be used in telehealth encounters.
