feel dizzy/slur their speech, stumble/find it hard to walk, and fall asleep without intending to. A SRE score, representing the average number of drinks needed to feel these intoxicating effects, was calculated. The higher the SRE score, the lower the effect per drink, and the lower the LR (Schuckit et al, 2009). Drawing from the participants who completed the initial Spit for Science survey within the first four weeks of the study (83% of the 2022 individuals), those with SRE scores greater or less than 0.25 standard deviations from the mean were considered eligible for the study, in order to compare individuals who clearly had a low versus high LR. Schuckit et al. (2012) used the same criterion for distinguishing low LR and high LR individuals; however, the overall mean SRE score (5.3, SD=2.12) in that study was lower than that of the present study (seen in Table 1). Enrollment was capped approximately four weeks after the initial survey to facilitate the timeline of the prevention programs; during this time, 323 of the invited 572 students expressed interest in participating (56.5%) and 231 were enrolled in the study. Participants included 171 females (72.2%), and the self-reported race/ethnicity was 0.4% American
