Assessing Adolescent Vaping Norms and Perceptions in a Statewide Multi-Community Project.

: Adolescent e-cigarette use has increased dramatically in recent years and is quickly becoming a serious public health issue. While studies have identified the influence of social norms on the use of traditional cigarettes, few have examined these factors in the context of e-cigarettes and other vaping devices. : The goal of this study was to examine social norms predictors of past 30-day e-cigarette use among high school students in 10 communities located in Minnesota. : In our sample (N = 3,285), students who believe most students in their school vape daily are more likely to have vaped in the past 30 days than those who believe most students vape weekly or less frequently. Further, students were likely to have used e-cigarettes in the past 30 days if they perceived that most students approved of vaping (i.e., they disagreed with the statement that, "vaping is not a good thing for anyone their age to do"). Findings from this study highlight social norms related to perceptions that increase the likelihood of past 30-day e-cigarette use. : Results from this study lend themselves to norms-based prevention science strategies that are critical to reducing e-cigarette use among high school students.
