The MANOVA model predicting alcohol abuse at Time 2 from the substance use onset variables also yielded a significant multivariate effect for the onset of regular drinking, F(6,434)=6.28, p<.001. Results indicated that individuals with an early onset of regular drinking drank more frequently to get high, F(2,218)=15.38, p<.001, and to get drunk, F(2,218)=5.40, p<.01, during their early 20s (see Figure 1). Young adults who had an early onset of regular drinking also had higher MAST scores, F(2,218)=9.61, p<.001, in comparison to those with a later onset of regular drinking (see Figure 2).
