Trauma and Very Young Children.

This article examines the intersection of early childhood mental health and trauma. Working definitions, incidence, and prevalence of trauma events for this population are outlined with an emphasis on children younger than age 4 years. Trauma impacts on early childhood development are reviewed, with attention to clinical consequences, protective factors, and resilience. Best practices for assessment, screening tools, and treatment methods are presented based on the current research. Future implications include clinician and researcher partnerships to increase the number of effective screening and intervention tools for addressing trauma in very young children.
