April 12, 2010 -- Moms who spank their 3-year-olds may be increasing their
children's risk of aggressive behavior, such as bullying, by the time they turn
5, a study shows.
The study, published in the May issue of Pediatrics, adds to evidence
suggesting that spanking and other types of corporal punishment set kids up for
aggressive behaviors later in life.
"Children need guidance and discipline; however, parents should focus on
positive, non-physical forms of discipline and avoid the use of spanking,"
study researcher Catherine A. Taylor, PhD, an assistant professor of community
health sciences at Tulane University School of Public Health and Tropical
Medicine in New Orleans, tells WebMD in an email. "This message is consistent
with that of the American Academy of Pediatrics, which 'strongly opposes
striking a child for any reason.'"
Taylor and colleagues asked about 2,500 mothers how often they had spanked
their 3-year-old child in the past month. Nearly half of the moms said they had
not spanked their child during the previous month, 27.9% said they spanked
their 3-year-old once or twice within the last month, and 26.5% percent said
they spanked their child more than twice in the past month.
The researchers also asked moms questions about their child's aggressive
behavior, such as whether they were bullies, cruel, mean, destructive, and/or
prone to getting into fights with others at age 3 and again at age 5.
Although other studies have shown a link between spanking and aggressive
behavior, the new study solidifies the connection because the researchers
controlled for other maternal risk factors that might have explained the link,
such as neglect, maternal use of drugs and alcohol, maternal stress and
depression, and the physical or psychological maltreatment of the child.
"This study reinforces that any kind of violence or physical aggression in
the home is another risk factor for kids being more aggressive in the future,"
says Patricia Hametz, MD, director of the Injury and Violence Prevention Center
and assistant clinical professor of pediatrics at Columbia University and
director of the general pediatrics inpatient service at New York-Presbyterian
Morgan Stanley Children's Hospital in New York City.
"The way you discipline depends on the age of the child, and pediatricians
should give age-appropriate suggestions about how to discipline toddlers,"
Hametz tells WebMD. "Some people like time-outs, which remove a child from
whatever it is that is overstimulating them."
Another tactic is to reward good behavior. "Praising, pointing out, and
literally rewarding good behavior is a better discipline strategy than
punishing bad behavior after it happens," she says.
Jennifer E. Lansford, PhD, a research scientist at the Duke University
Center for Child and Family Policy in Durham, N.C., agrees. "These findings
suggest that spanking has the unintended consequence of increasing children's
aggressive behavior, so the implication for parents would be that they should
not use corporal punishment, but find other ways of managing their children's
misbehavior and promoting good behavior," she says in an email.
This may include teaching about good and bad behavior and trying to prevent
misbehavior rather than just reacting to it once it has occurred, she suggests.
"Parents can use reward systems such as sticker charts, where a child earns a
sticker or something else for good behavior, and special privileges such as
extra time with mom or dad can be offered for completing the sticker
The new findings make sense to child psychologist Vincent J. Barone, PhD, an
associate professor of pediatrics at the University of Missouri-Kansas City
School of Medicine and the director of Developmental and Behavioral Sciences
South Clinic at Children's Mercy Hospital and Clinics, also in Kansas City.
"The findings in this research are consistent with what we know about
violent experiences for children. Whether a violent video game or corporal
punishment, children learn aggressive attitudes and act them out when they are
exposed to violence," he says. "Children don't learn peaceful ways of solving
conflict when they are exposed to violence."
Barone usually suggests that parents briefly describe the inappropriate
behavior and then use a time-out.
Also, he suggests, "use your attention and passion to describe and praise
positive behaviors such as cooperation, thoughtfulness, and respect for
