Using an e-mail prompted web-based questionnaire, 19 participants were asked to report both BAC estimates and subsequently measured BAC levels over the course of 27 days. Results from the 14 subjects who reported drinking during that time period suggest that BAC estimation improves over the first four drinking events, only when controlling for amount of alcohol consumed. BAC estimate accuracy was found to decrease as number of drinks and measured BAC increased. Participants were more likely ...
