How accurate are college student’s perceptions of the percent of their peers that misuse prescription drugs? Do these normative perceptions influence their own personal misuse? A recent study explored these questions in relation to the misuse ofprescription stimulants by college students. In this study, a random sample of undergraduates (n=1,106) from a large university completed an online questionnaire where they self-reported their misuse of prescription stimulants, consumption of alcohol, as well as their normative perceptions related to these issues. In this study, 89% of participants perceived that the typical college student had misused prescription stimulants at least once in their lifetime. However, only 19% of participants reported actual lifetime misuse of prescription stimulants, with only 10% of this population reporting misuse on three or more occasions. In addition, a positive correlation existed between perceived norms and personal misuse, suggesting students whom overestimated their peer’s misuse were more likely to misuse themselves. Take Away: This study adds to the growing body of literature that demonstrates higher normative perceptions of substance misuse often stimulate greater personal use. When implementing prevention resources for prescription drug misuse, consider addressing actual v. perceived misuse—chances are, correcting this misperception may prove effective.
