Smacking children can lead to mental health issues

A new study reveals the lasting impact.

A new study from the University of Texas at Austin and the University of Michigan found physical discipline during infancy can be detrimental to both behaviour and mental health in later years.

Researchers studied data collected from more than 160,000 children over a 50 year period. They discovered that smacking, defined as an open-handed hit on the behind or extremities, led to anti-social behaviours, aggression and mental health issues in adulthood.

“We found that spanking was associated with unintended detrimental outcomes and was not associated with more immediate or long-term compliance, which are parents’ intended outcomes when they discipline their children,” says Elizabeth Gershoff, an associate professor of human development and family sciences at The University of Texas at Austin.

“The upshot of the study is that spanking increases the likelihood of a wide variety of undesired outcomes for children. Spanking thus does the opposite of what parents usually want it to do,” adds study co-author Andrew Grogan-Kaylor, an associate professor at the University of Michigan School of Social Work.

Not only that, but the team were able to further identify that those who were smacked more likely to do the same to their own children – showing a direct example physical punishment being passed from generation to generation.

According to a 2014 UNICEF report, a whopping 80 per cent of parents worldwide still smack their children.

In New Zealand, the "anti-smacking" law was passed in 2007 after a nationwide referendum, and removed the defence of "reasonable force" for adults who smacked their children.

Gershoff hopes that the new research educates and encourages parents to try positive and non-punitive forms of discipline.

“We as a society think of spanking and physical abuse as distinct behaviors,” she says. “Yet our research shows that spanking is linked with the same negative child outcomes as abuse, just to a slightly lesser degree.”
