The results support all three original hypotheses. Regarding Hypotheses 1, recognizing that any intervention could do harm, the data in Table 2 and the main time effect in Table 3 indicate that drinking levels decreased over time or remained unchanged for all six LR status by education group pairings. Regarding Hypothesis 2, the predicted pattern of greater decreases in heavy drinking for Low LR participants in the LRB Group was observed, with statistical significance remaining even when considering racial/ethnic backgrounds. This conclusion was supported in Table 3 by the 3-way interactions for LR by education group by time for maximum quantities, and a trend (p=.06) for usual quantities. The Hypothesis 3 prediction that High LR students would decrease drinking more in the SOTA Group was also consistent with the results, perhaps because predispositions toward heavy drinking by High LRs may relate to risk factors other than Low LR (e.g., impulsivity or negative affect), and these predispositions may have been easier for students to identify with in the SOTA Group where those issues were discussed more extensively.
