. Introduction
Alcohol use is a major social problem throughout the world. One particularly alarming aspect over several
decades has been that of alcohol use by adolescents (Chung & Martin, 2011; Kornblum & Julian, 2007). The
social concern about adolescent alcohol use is exacerbated by the fact that early alcohol use is associated with an
increased risk for problem behaviours, such as legal problems (Rockhole, 2011). More specifically, alcohol is the
main cause of death for people less than 21 (NIAAA, 2005).
