PLAN= plan to drink over the weekend (1=Yes, 0=No); GOAL= willingness to commit to a drinking-limit goal over the weekend (1=Yes, 0=No); BINGE= any weekend binge drinking episode (1= greater than 4/3 drinks for men/women, 0=less than 5/4 drinks for men/women); MAX= most number of alcoholic drinks consumed over any one occasion over the weekend (continuous); Time= Weeks (1–6).
