Behavioral pediatrics is a multidisciplinary field that involves many healthcare specialists revolving around the practicing pediatrician and primary care clinician; also, various additional, associated fields of training have developed such as developmental-behavioral pediatrics, neurodevelopmental pediatrics, pediatric psychodermatology and medical care for those of all ages with developmental disabilities. Experts in psychiatry and psychology work closely with pediatric clinicians in a variety of professional relationships, including co-located and non-co-located mental health settings. Pediatricians can provide a wide variety of care to children and adolescents with complex disorders, depending on their training as well as interests, and this book seeks to provide au courant perspectives in behavioral pediatrics. Behavioral health screening remains an important task of pediatricians and behavioral pediatricians as they evaluate their pediatric patients.
