Abstract Parent-child physical aggression, including both physical punishment and abuse, remains a prevalent problem in the United States. In this paper, we briefly review the prevalence and harms of parent-child aggression and discuss changes in social norms and policies over the past several decades. Then, we discuss broad social policies influencing risk for parent-child physical aggression, policies relevant to reducing and preventing physical abuse, and policies relevant to reducing and preventing physical punishment. We close by considering future directions to strengthen research and evaluation and accelerate progress toward ending parent-child physical aggression.
