Clinical use and implementation of the diagnostic classification of mental health and developmental disorders of infancy and early childhood

Abstract

The Diagnostic Classification of Mental Health and Developmental Disorders of Infancy and Early Childhood (DC: 0–5) was developed to provide a framework for diagnosis of infants and young children, and a training curriculum supports implementation of the manual in clinical practice. This study surveyed 100 mental health clinicians (93% female and 53% Latinx/Hispanic) who had completed training in the DC: 0–5 classification system and worked with infants/young children and their families primarily in urban, public insurance‐funded, community mental health settings in the United States. The survey explored their use of the diagnostic manual in clinical practice as well as supports and barriers to implementation. Survey results indicated a high level of adoption of the manual in clinical practice, although all five axes and the cultural formulation were used less often than the Axis I Clinical Disorders section. Barriers to implementation included systemic issues such as agency and billing requirements necessitating simultaneous use of other diagnostic manuals, lack of supports and expertise within their agency, and difficulty making time to fully utilize the manual. The findings suggest that policy and systems changes may be needed to enable clinicians to fully integrate the DC: 0–5 into their case conceptualizations.

Assessment and Diagnostic Classification Using DC:0-5 in Early Childhood Mental Health Clinics: The Protocol for the Developmental Psychiatry Diagnostic Challenges Study (DePsy)

“…In providing a framework for the standardized psychiatric assessment of psychopathology in infants, toddlers, and preschool children [4], the DC:0-5 is currently widely used by clinicians working in the field of infant and early childhood mental health [21]. In contrast to its clinical utility, studies empirically corroborating the DC:0-5 are scarce.…”
