Peer approval is the best indicator of the tendency for new college students to drink or smoke, even if they don’t want to admit it, according to a new study.

This new finding is key to help universities address the problems of underage or binge drinking, says lead author Nancy Rhodes, an associate professor in the advertising and public relations department at Michigan State University.

“…the messages need to come from peers themselves, not authority figures.”

“We need to change our intervention approach to amplify the voices of those who don’t approve of this kind of behavior, such as students who are disturbed at 3 am by drunk dormmates arriving home,” Rhodes says.

“We suggest that emphasizing the social costs of these behaviors may be a promising strategy. Most importantly, the messages need to come from peers themselves, not authority figures.”

Previous studies and social-norm approaches to curb these risky behaviors have focused on the perceived prevalence of students who drink or smoke, not whether the behavior is socially approved.

“Students don’t want to admit they’re influenced by friends.”

“More than their family’s influence or how many students they think are participating in a risky behavior, students choose to drink or smoke based on if they believe their small circle of peers will approve,” says Rhodes, who studies persuasion and social influence.

“Students don’t want to admit they’re influenced by friends. They think they are making independent choices, but the reality is they are seeking acceptance.”

Rhodes’ research involved 413 first-year college students living in on-campus residence halls. The researchers chose first-year students because they’re developing their independence and behavioral attitudes away from their families.

The researchers tested students on how quickly they responded to descriptions of drinking and smoking mixed in with other behaviors. They answered “yes” or “no” if they believed their family and friends wanted them to engage in those behaviors.

Students who quickly indicated their peers approved of them drinking signified higher drinking and smoking intentions. On the contrary, how quickly they indicated their parents approved of drinking and smoking had no effect on intention.

“This is referred to as cognitive accessibility, or the ease of activating something from memory,” Rhodes says. “How quickly do they respond to the questions? How quickly do they say their friends want them to drink? How quickly do they say their friends want them to play drinking games? How fast they agree is what matters and predicts future behavior.”

The research appears in Health Education and Behavior.
