Handbook of Preschool Mental Health: Development, Disorders, and Treatment offers a comprehensive exploration of psychiatric disorders in children aged 2 to 6 years. Edited by Joan L. Luby, this second edition has been thoroughly revised to include the latest scientific and clinical advancements. Leading researchers delve into how behavioral and emotional problems emerge during this period of rapid development and brain changes, providing insights on conditions such as conduct disorders, attention-deficit/hyperactivity disorder, anxiety disorders, depressive disorders, autism spectrum disorder, attachment disorders, and sleep disorders. The handbook reviews a range of interventions for preschoolers and their caregivers, including detailed descriptions of clinical techniques. New to this edition are contributions from many new authors, an increased focus on brain development and neural correlates, a section on risk and resilience that includes chapters on sensitive periods of development and the early environment, and chapters dedicated to parent-child interaction therapy, cognitive-behavioral therapies, attachment-based therapies, and translational approaches to early intervention. This authoritative resource is essential for mental health professionals, researchers, and educators working with young children.
