program based on level of response to alcohol, but these LR-tailored prevention programs may have incremental effects over standard programs when protocol adherence – and exposure to the educational content – is high. However, our results do support the effectiveness of prevention programs for individuals at high risk for alcohol problems based on low LR to alcohol. In both prevention programs, individuals with a low LR showed a greater decrease over time than those with a high LR, particularly in high-risk behaviors like heavy episodic drinking (MAX24 and days drinking four or more drinks). As high LR individuals did not experience as great a benefit as low LR individuals from either program, it may be that any kind of prevention program is advantageous to high-risk individuals, with programs tailored toward specific risk factors potentially providing incremental benefits if protocol adherence is high.
