  1. aAnalyses employed Action scale as a continuous measure (see Table 1). Median split values on this table are provided for descriptive purposes.
  2. bAUDIT-C is a composite measure that consists of respondents scores on frequency of drinking, drinks per drinking day, and frequency of five or more drinks on one occasion. Scores range from 0–12.
