Where college students look for vaping information and what information they believe.

This convergent mixed methods study examined how information sources influence college students' beliefs and knowledge about vaping. College students either completed a survey ( = 522; January-April, 2016) or were interviewed ( = 33; 2015-2016). College students completed an online survey asking 'where' students had heard about e-cigarette and 'what' they had heard. Responses were quantified and a chi-square analysis was conducted. Additional college student e-cigarette users were interviewed about the credibility of information sources. Thematic analysis was conducted with the coded interviews. There was a significant relationship between information sources for e-cigarettes (social sources, media, advertising, education/research) and the messages they recalled. Friends who vaped and e-cigarette users were the most credible information sources. Confirmation bias and scientific impotence bias characterized assessment of e-cigarette information. Health education specialists working on college campuses should provide accurate information via communication channels most unitized by college students.
