DC:0-3R is the 2005 revision of ZERO TO THREE’s Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood (DC:0-3).
ZERO TO THREE published DC:0-3 in 1994 to address the need for a systematic, developmentally based approach to the classification of mental health and developmental disorders in the first 4 years of life. It was the first-ever attempt by a group of experienced clinicians to formulate a useful scheme that would complement, but not replace, existing medical and developmental frameworks.
In the 10 years since its publication, DC:0-3 has become increasingly valued as a complement to The Diagnostic and Statistical Manual of Mental Disorders of the American Psychiatric Association (DSM-III-R) and the International Classification of Diseases of the World Health Organization (ICD 9). DC:0-3 has been published in 8 additional languages, increasing its accessibility to clinicians around the world.
Introducing DC:0-3R, an article from the September 2005 ZERO TO THREE Journal, provides an overview of the 2005 revision.
