The main aim of this guide is to provide technical advice for setting up policies and programmes for child maltreatment prevention and victim services that take into full account existing evidence on the effectiveness of interventions and that use the scientific principles of the public health approach. This will encourage the implementation of scientifically testable interventions and their evaluation. It is hoped that, in this way, the guide will contribute to a geographical expansion of the evidence base to include more evaluations of interventions from low-income and middle-income countries, and a greater variety of evaluated interventions. The long-term aim is to be able to prepare evidence-based guidelines on interventions for child maltreatment. This guide is intended for policy-makers and programme planners working at national, provincial and municipal levels in the sectors of health, social services and the law.
