Process evaluation




Awareness of drinking





T2 posttest 5.33 (1.56) 5.64 (1.44) 5.51 (1.51) 5.65 (1.43) 5.53 (1.49)
Contemplation of intervention





T2 posttestb 2.83 (1.91) 3.23 (2.05) 3.28 (1.96) 3.70 (2.18) 3.23 (2.04)
Tried to reduce drinking





T2 posttestc 4.49 (2.09) 5.00 (2.09) 4.95 (2.13) 5.22 (2.11) 4.89 (2.12)
Self-characterization





T1 baseline
5.42 (0.92)
5.46 (0.87)

T2 posttest
5.57 (0.86)
5.66 (0.83)

T3 follow-up
5.63 (0.84)
5.73 (0.82)

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.
