Some ten to twenty percent of school-age populations have mental health problems requiring intervention, and current policy initiatives identify evidence-based therapies as the most effective and relevant forms of treatment. This handbook helps bridge the gap between children’s needs and services, and between research, training, and practice, by reviewing EBTs across a wide spectrum of conditions. With more than thirty chapters and over fifty leading contributors, the Handbook covers a wider range of disorders and age ranges than competitor volumes. Several EBT options, both proven and promising, are offered for each covered disorder, bolstered by case examples, tables, and reference lists. Features include chapters on implementation issues such as diversity, family treatment, assessment strategies, and community settings, and step-by-step guidance for the researcher looking to gather empirical support for therapies.
