This handbook, with accompanying clinical workbook, provides information on the nature, diagnosis, assessment, and treatment of attention deficit hyperactivity disorder (ADHD). In-depth treatment guidelines are supported by updated documentation on outcomes. The book includes contributions from leading scientist-practitioners, who report on their respective areas of expertise. The volume begins with an historical perspective on ADHD, laying out its primary symptomatology and diagnostic criteria. Information is provided on the nature of ADHD, its prevalence, etiologies, and developmental course, comorbid psychiatric disorders, and associated cognitive and neuropsychological deficits. It critically evaluates DSM-IV diagnostic criteria and explains ADHD as a developmental problem of self-control. A comprehensive range of assessment and management approaches is then presented. The clinical interview, the medical examination, and the completion and scoring of behavior rating scales are described, as are applications of other tests. Eight case examples help facilitated effective diagnosis and treatment planning. Designed for practical use, the volume delineates recommendations for biopsychosocial interventions in clinical, school, and community settings. Modalities covered include parent counseling and training, family therapy with teens with ADHD, classroom management, including an account of a highly successful peer mediation program, and pharmacological approaches for individuals with ADHD. Three chapters focus specifically on adults with ADHD. A clinical workbook that provides a master set of the assessment and treatment forms, questionnaires, and recommended handouts accompanies the book. (Each chapter includes references.) (CR)
