This handbook explores the rapid growth in childhood developmental disabilities (DD) treatments. It reviews current evidence-based treatments for common psychopathologies and developmental disorders and evaluates the strengths of the treatments based on empirical evidence. Spanning infancy through the transition to young adulthood, chapters provide definitions, etiologies, prevalence, typical presentation and variants, assessment and diagnostic information, and age considerations. Chapters also review established and emerging psychological approaches and pharmacotherapies for cognitive, behavioral, emotional, medical, academic, and developmental issues as diverse as mood disorders, the autism spectrum, memory problems, feeding disorders, Tourette syndrome, and migraines. The wide range of topics covered aids practitioners in working with the complexities of young clients’ cases while encouraging further advances in an increasingly relevant field. Topicsfeatured in this handbook include:An introduction to Applied Behavior Analysis. Parent training interventions. Treatment strategies for depression in youth. Assessment and treatment of self-injurious behaviors in children with DD. Treatment approaches to aggression and tantrums in children with DD. Interventions for children with eating and feeding disorders. The Handbook of Childhood Psychopathology and Developmental Disabilities Treatment is a must-have resource for researchers, graduate students, clinicians, and related therapists and professionals in clinical child and school psychology, pediatrics, social work, developmental psychology, behavioral therapy/rehabilitation, child and adolescent psychiatry, and special education.
