More than 1,800 random late-night blood alcohol tests with matched surveys have been conducted every night of the week spanning every month of the school year. 60% of students sampled had a BAC level of 0.00% and 75% were at 0.05% or less. Very strong social norms messages can be developed from these data to bolster the credibility of self-report based media campaigns. Protocols for data collection, sample BAC distributions, and an assessment of the agreement of measured BAC levels with estimated BAC levels from self report survey data with will be presented. Cost-effective implementation strategies will be presented.
