DC:0–5™ Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood (V2.0 Print)

DC:0–5™ (Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood) Version 2.0 is the definitive diagnostic manual for professionals working with children from birth through age 5. Used worldwide by clinicians and early childhood specialists, it offers a developmentally grounded approach to identifying and treating mental health and developmental disorders in the earliest years, when intervention matters most.

First introduced in 1994 and widely trusted across disciplines, Version 2.0 sharpens clinical precision through a comprehensive five-axis system that integrates developmental context, relationships, and psychosocial stressors. It equips professionals to diagnose conditions not fully addressed in other systems, apply criteria with confidence, communicate clearly across teams, and align with standardized diagnostic codes. The result is earlier identification, stronger care planning, and better outcomes for children and families.

Fully updated to reflect current research and clinical practice, Version 2.0 includes refined guidance for children up to age 5, expanded considerations for younger ages, and updated diagnostic algorithms for emerging and evolving disorders.
