To determine the frequency of adolescent binge drinking, participants were asked to report how often they drank 6 or more cans, bottles, or drinks of beer, wine, or liquor in the last 6 months. A summed score reflecting the number of times adolescents drank 6 or more drinks of beer, wine, and liquor was created, with greater scores indicating greater frequency of binge drinking. The distribution was skewed (approximately 20% of participants reported binge drinking at least once in the last 6 months). Therefore, binge drinking was logarithmically transformed for the analyses.
