Diagnosis to Function: Classification for Children and Youths

This article provides an overview of a newly approved World Health Organization framework and classification system for human functioning. The International Classification of Functioning, Disability, and Health (ICF) identifies dimensions of human functioning and describes a common language for clinical practice, research, and policy development across disciplines and service systems. This presentation highlights the development of a version of the ICF for children and youths (ICF-CY) and its potential utility in developmental and behavioral pediatrics. Clinical, research, and policy dimensions are described. Limitations related to scope and clarity of the framework are also outlined. The article proposes that serious consideration be given the ICF-CY as an integrated system to clarify constructs, improve communication, and encourage coordination of health services for children and youths.
