Latent growth curve analyses according to the intention-to-treat principle revealed that participants in the experimental condition had significantly lower weekly alcohol consumption compared to participants in the control condition that was sustained at 3-month follow-up (intercept=--2.60, P<.001; slope=0.16, P=.08). Additional linear regression analyses indicated that this intercept difference resulted from significantly higher levels of alcohol units per week for participants in the control condition compared to those in the experimental condition at 1-month (beta=--2.56, SE 0.74, Cohen's d=0.20, P=.001), 3-month (beta=--1.76, SE 0.60, Cohen's d=0.13, P=.003), and 6-month (beta=--1.21, SE 0.58, Cohen's d=0.09, P=.04) follow-up intervals. Latent growth curve analyses further indicated that participants in the experimental condition had a significantly lower frequency of binge drinking compared to participants in the control condition that was sustained at 6-month follow-up (intercept=--0.14, P=.01; slope=0.004, P=.19). This intercept difference resulted from higher levels in this outcome for participants in the control condition relative to participants in the experimental condition at 1-month (beta=--1.15, SE 0.06, Cohen's d=0.16, P=.01), 3-month (beta=--0.12, SE 0.05, Cohen's d=0.09, P=.01), and 6-month (beta=--0.09, SE 0.05, Cohen's d=0.03, P=.045) follow-up intervals. Conclusions: The WDYD intervention was shown to be effective in preventing an increase in weekly alcohol consumption and frequency of binge drinking directly after the intervention. This effect was sustained 3 and 6 months after the intervention.
