Unique in the breadth and depth of its coverage, this volume reviews the principal methods for assessing psychopathology in children aged 6-17. Chapters from preeminent scholars describe interviewer- and respondent-based diagnostic interviews; scales and interviews used for specific disorders, such as the disruptive, anxiety, and pervasive developmental disorders; and key biological measures. Also addressed are the empirical and theoretical bases of DSM-IV and ICD-10 classifications, cross-cultural and developmental issues, the assessment of family impairment history, and retrospective adult assessment of childhood. This book provides up-to-date knowledge that is central to effective clinical and research practice.
