This book explores the factors necessary for successful implementation of interventions that foster productive relationships and ecologies to establish, reinforce, and sustain adaptive patterns of emotional and behavioral functioning across childhood and into adulthood. Although there has been a concerted focus on developing evidence-based programs and practices to support the needs of children and youth with emotional and behavioral disorders, there has been less emphasis on the developmental, social, and environmental factors that impact the implementation and effectiveness of these approaches. Chapters from leading experts tackle this complexity by drawing on a range of disciplines and perspectives including special education; mental health services; school, clinical, and community psychology; social work; developmental psychology and psychopathology; and prevention science. An essential resource for scholars and students interested in emotional and behavioral disorders, this volume crafts an essential framework to promote developmentally meaningful strategies for children and youth with even the most adverse experiences and intensive support needs.
