Student Bullies More Likely To Use Alcohol, Marijuana
Students who bully their classmates are more likely than others to use substances such as alcohol, cigarettes and marijuana, according to a new study by researchers at Ohio State University.
“Our findings suggest that one deviant behavior may be related to another,” said Kisha Radliff, lead author of the study and assistant professor of school psychology at the Ohio State University.
“For example, youth who bully others might be more likely to also try substance use. The reverse could also be true in that youth who use substances might be more likely to bully others.”
Students who were both perpetrators and victims of bullying were also more likely to be substance users than kids who were uninvolved or were victims only.
The researchers used data from a survey of 74,247 students enrolled in all public, private and Catholic middle and high schools in Franklin County, Ohio (which includes Columbus).
Among the 152 questions on the survey were eight that involved bullying, either as a victim or perpetrator.
Students were asked about how often they told lies or spread false rumors about others, pushed people around to make them afraid, or left someone out of a group to hurt them. They were also asked how often they were the victims of such actions.
The survey also asked how often the students used cigarettes, alcohol and marijuana.
For this study, users were defined as those who reported using these substances at least once per month.
The results showed that bullying was more common among middle-school students than those in high school, while substance use was more prevalent among high-school students.
About 30 percent of middle-school students were bullies, victims or bully-victims, compared to 23 percent of those in high school.
Fewer than 5 percent of middle-school youth used cigarettes, alcohol, or marijuana.
But among high-school students, about 32 percent reported alcohol use, 14 percent used cigarettes and 16 percent used marijuana.
However, substance use varied depending on involvement in bullying, the researchers found. For instance, among middle-school students, only 1.6 percent of those not involved in bullying reported marijuana use, while 11.4 percent of bullies and 6.1 percent of bully-victims used the drug. The survey found that 2.4 percent of victims were marijuana users.
Among high school students, 13.3 percent of those not involved in bullying were marijuana users — compared to 31.7 percent of bullies, 29.2 percent of bully-victims, and 16.6 percent of victims.
Similar results were found for alcohol and cigarette use.
Since percentages do not tell the whole story, the researchers also used a statistical analysis that showed that bullies and bully-victims had much higher than expected levels of substance use, Radliff said.
“That suggests there is a relationship between experimenting with substances and engaging in bullying behavior,” she said.
Statistically, however, there was no connection between being a victim and substance use among middle-school students, she added.
The use of cigarettes and alcohol was statistically greater for victims in high school, but there was no statistically significant effect on marijuana use.
Nevertheless, it was the bullies and bully-victims who were the most likely to be substance users.
Radliff said the study might lead to improvements in anti-bullying initiatives.
“Many schools are mandating anti-bullying programs and policies, and we think they need to take this opportunity to address other forms of deviant behavior, such as substance use,” she said.
This could be particularly important in middle school, where bullying is more prevalent, but substance use is still fairly rare.
“If we can intervene with bullies while they´re in middle school, we may be able to help them before they start experimenting with substance use,” she said.
The study appears in the April 2012 issue of the journal Addictive Behaviors.
