For decades, parents have debated whether spanking is an effective form of discipline or whether it may cause more harm than good. A large review of research spanning 50 years suggests that spanking is associated with a range of negative long-term outcomes. Published in the Journal of Family Psychology, the analysis examined data from more than 160,000 children and found consistent links between spanking and poorer developmental outcomes.

According to the researchers, children who were spanked were more likely to exhibit aggressive behavior, mental health difficulties, antisocial behavior, and learning challenges as they grew older. Although the study distinguished spanking from physical abuse, the authors concluded that many of the long-term effects were similar in nature, though generally less severe in cases of spanking.

Lead researcher Elizabeth Gershoff said the findings suggest that spanking often has the opposite effect of what parents intend. Rather than improving behavior, it may increase defiance and raise the likelihood that children will use physical punishment with their own children later in life, potentially continuing the cycle across generations.

In light of these findings, many child development experts recommend positive discipline strategies instead of physical punishment. Approaches such as setting clear expectations, praising positive behavior, using logical consequences, and calmly discussing problems can help children develop self-control while strengthening the parent-child relationship. Researchers emphasize that discipline is most effective when it teaches appropriate behavior, encourages trust, and supports healthy emotional development.
