2.1. Sample
A self-administered online survey via Qualtrics was sent to a simple random sample of 5000 currently enrolled University of Florida (UF) undergraduate students. The total undergraduate population at UF was 35,043 (female: 19,355 (55.2%), male: 15,688 (44.8%)). A request was made to the UF Office of Institutional Planning and Research for the simple random sample of currently enrolled undergraduate students. The Excel file received only contained student emails with no other identifying information provided. No incentives were provided to students for participation. Data were collected from 25 April to 3 June 2017. In order to participate in the study, students had to: (1) be currently enrolled (full-time or part-time) at the University of Florida, (2) be undergraduate students, (3) have the ability to read and write in English, and (4) have a valid UF email address. Overall, 1087 students completed the survey, resulting in a response rate of 21.7%.Potential respondents were emailed an introductory letter describing the study, potential benefits and harms of participation, Institutional Review Board (IRB) contact information and approval/number, and an individualized/personalized link to the survey. Additionally, respondents were not offered an incentive to take the survey. Respondents had two weeks to complete the survey after they started. Consistent with the Dillman Total Design Method of survey administration, after the introductory email, three automated personalized reminder emails were sent to non-respondents every three days [
