The model predicting alcohol abuse at Time 1 yielded a significant multivariate effect for the onset of regular drinking, F(6,424)=2.78, p<.05. As shown in Figure 1, individuals with an early onset of regular drinking drank more frequently to get high, F(2,213)=7.29, p<.01, and to get drunk, F(2,213)=5.73, p<.01. In addition, those with an early onset of regular drinking had higher MAST scores, F(2,213)=4.29, p<.05, in comparison to those with a later onset of regular drinking (see Figure 2).
