Description: The prevalence of Alcohol Use Disorders is rapidly increasing among college students. The use of real time monitoring in conjunction with contingency management procedures to reduce alcohol consumption has only recently been developed. Therefore, the purpose of this study was to learn more about natural patterns of alcohol consumption in college-aged adults. A second goal was to evaluate a novel, handheld technology for obtaining reliable samples over extended time periods. College students were given a SoberLinkTM SL2 breathalyzer for eight weeks to monitor their drinking behaviors and asked to self-report the number of drinks consumed each day. Participants received one to three text messages per day to provide breath samples and earned monetary rewards for submitting samples within the allotted time. The results of this study showed that college students tend to consume alcohol during the evening hours and mostly on the weekends. There was a weak to medium correlation between average breath alcohol concentration and conditional average drinks. Compliance with prompts ranged between 77 and 84 percent and monetary earnings ranged between $152 and $160. Naturalistic observations of college drinking may aid in the development of interventions to prevent excessive drinking and the SL2 breathalyzer may have great potential to be used in a number of therapeutic approaches.
