a There were only means for self-characterization at baseline for the prototype and combination condition. Differences for contemplation and trying to reduce drinking are significant at P<.05. Analyses were corrected for age and level of education.
b Original Drinktest and Combined differ.
c Original Drinktest and Prototype differ, and Original Drinktest and Combined differ.
