This volume attains a central goal of the field of Developmental Psychopathology, that of facilitating the mutually enriching interplay between research and practice. An eminent group of theoreticians, researchers, and clinicians, many of whom span all three areas in their professional pursuits, bring their knowledge to bear on aspects of prevention and intervention. Contributors discuss issues confronting those invested in preventing or ameliorating psychopathology and describe innovative programs that have been developed to demonstrate the effectiveness of various therapeutic strategies for addressing issues such as Attention Deficit Hyperactivity Disorder, parenting in substance abusers, attachment relationships between foster parents and infants in their care, preventive interventions for children with depressed parents, and school-based preventive interventions. Professionals invested in developing and evaluating prevention and intervention programs, those providing treatment, and those decision makers who need to ascertain which services are most effective and, thereby, warrant funding, will all find this volume to be invaluable.
