Parenting is a critical influence on the development of children across the globe. This handbook brings together scholars with expertise on parenting science and interventions for a comprehensive review of current research. It begins with foundational theories and research topics, followed by sections on parenting children at different ages, factors that affect parenting such as parental mental health or socioeconomic status, and parenting children with different characteristics such as depressed and anxious children or youth who identify as LGBTQ. It concludes with a section on policy implications, as well as prevention and intervention programs that target parenting as a mechanism of change. Global perspectives and the cultural diversity of families are highlighted throughout. Offering in-depth analysis of key topics such as risky adolescent behavior, immigration policy, father engagement, family involvement in education, and balancing childcare and work, this is a vital resource for understanding the most effective policies to support parents in raising healthy children.
