This handbook provides a comprehensive discussion of the key elements which should be part of any successful programme tailored to the needs of children with diagnosable mental, behavioural, or emotional disorders. The overall goal of the book is to provide an overview of the psychological services available to children and adolescents in school and services community settings. The book is divided into five parts: "Framing the Issues," "Delivering Psychological Services in Diverse Settings," "Preventive Interventions," "Treatments with Specific Populations," and "System-Level Consultation."
