Up-to-date information on successfully assessing children and adolescents in clinical settings This book showcases state-of-the-art assessment methods, instruments, and processes in the clinical assessment of children and adolescents. Written by leading experts, the book highlights skills and specific procedures that are relevant and distinctive for the assessment of different age groups and in different contexts so that professionals can plan interventions effectively. After an introduction to the basic concepts and approaches to the clinical assessment of children and adolescents, four further sections explore the diagnosis of psychological problems, the conceptualization of clinical problems and interventions, the assessment of intervention progress and outcomes, and the assessment of specific groups and in special contexts. The contributions are full of practical examples to address issues such as clinical judgement and bias, results integration, multi-informant data collection, and incremental validity.
