Based on over a decade of research and best practice, this book explores programs that have targeted eight areas identified as the most pressing social problems affecting infants, children and youth. These include developmental problems in infancy and early childhood, child maltreatment, youth violence and developmental delays. Each program is closely examined and the characteristics that make it successful are described, along with the challenges that still need to be addressed. Other areas examined are: adolescent substance abuse risky sexual behaviour dating violence marital conflict and divorce. The interplay between the science of research and the art of practice is emphasised, showing how such preventive work can help save time, money and resources. ‘Invaluable in assisting our communities in using an ounce of prevention early on instead of relying on a pound of cure later.’ ?From the foreword by Judith Carta, PhD.
