Child maltreatment is a global public health problem. It can have detrimental and long-lasting effects on the development and health of children and occurs most frequently at the hands of parents and caregivers. These guidelines provide evidence-based recommendations on parenting interventions for parents and caregivers of children aged 0-17 years that are designed to reduce child maltreatment and harsh parenting, enhance the parent-child relationship, and prevent poor parent mental health and child emotional and behavioural problems. The guidelines are relevant to low-, middle- and high-income countries in all world regions. The recommendations in these guidelines are intended for a wide audience, including policy makers, development agencies and implementing partners, government health and social workers, and nongovernmental organizations.
