American Academy of Pediatrics. The new morbidity revisited: a renewed commitment to the psychosocial aspects of pediatric care. Committee on Psychosocial Aspects of Child and Family Health

In 1993, the American Academy of Pediatrics adopted the policy statement "The Pediatrician and the 'New Morbidity.'" Since then, social difficulties, behavioral problems, and developmental difficulties have become a main part of the scope of pediatric practice, and recognition of the importance of these areas has increased. This statement reaffirms the Academy's commitment to prevention, early detection, and management of behavioral, developmental, and social problems as a focus in pediatric practice.
