This book presents an integrated and coordinated framework for assessing developmental, psychological, and behavioral disorders in early childhood. Expert contributors advocate for natural-environment methods in addition to standardized measures in assessing academic and social skills as well as age-specific behavior problems in young children. Chapters model collaborations between clinicians, family, and daycare and school personnel, address diagnostic and classification issues, and conceptualize assessment as flexible, ongoing, and, as necessary, leading to coordinated services. The book gives practitioners and researchers critical tools toward establishing best practices in an increasingly complex and important area, leading to better prevention and intervention outcomes. Included in the coverage: • Standardized assessment of cognitive development. • Authentic and performance-based assessment. • The use of Response to Interve ntion (RTI) in early childhood. • Collaboration in school and child care settings. • Anxiety disorders, PTSD, OCD, and depression in young children. • Sleeping, feeding/eating, and attachment problems in early childhood. is an essential resource for clinicians and related professionals, researchers, and graduate students in child and school psychology; assessment, testing, and evaluation; occupational therapy; family studies, educational psychology; and speech pathology.
