Between 10 and 20 per cent of children and adolescents suffer from psychological problems serious enough to warrant psychological treatment (Carr, 1993 ). For clinical psychologists working with children and adolescents, and for those who use and fund these psychological services, a central concern is what psychological interventions are most effective for which particular problems (Kendall and Chambless, 1998; Paul, 1967). Our book aims to answer this question. Our answer is based on a thorough review of rigorously conducted treatment outcome research.
