An unparalleled resource for accurately diagnosing an array of childhood problems Psychodiagnostic Assessment of Children: Dimensional and Categorical Approaches provides comprehensive guidelines for assessing and diagnosing a broad spectrum of childhood disorders. In this groundbreaking new text, Randy Kamphaus (coauthor of the BASC and BASC-II) and Jonathan Campbell discuss both theoretical and practical aspects of the field. Their detailed coverage provides students and professionals with important research findings and practical tools for accurate assessment and informed diagnosis. This monumental new work begins by explaining dimensional (e.g., classification methods that emphasize quantitative assessment measures such as behavior rating scales) and categorical (e.g., classification methods that emphasize qualitative assessment measures such as clinical observation and history-taking) methods of assessment and diagnosis. It then highlights assessment interpretation issues related to psychological assessment and diagnosis. The remainder of the text covers constructs and core symptoms of interest, diagnostic standards, assessment methods, interpretations of findings, and case studies for all of the major childhood disorders. The disorders include: * Mental retardation * Learning disability * Autism spectrum disorders * Depression * Anxiety disorders * Traumatic brain injuries * Eating disorders * Attention deficit hyperactivity disorder * Conduct disorder * Oppositional defiant disorder * Substance abuse and dependence * Subsyndromal and hypersyndromal impairments
