Regarding Hypothesis 2, SRE-T scores correlated more closely with heavy drinking and alcohol problems than SRE-5. This result is consistent with the concept that SRE-5 might primarily reflect a person’s sensitivity to alcohol, whereas SRE-T values are also likely to reflect the depth of development of intersession alcohol tolerance. It is also possible that the stronger association of SRE-T to alcohol problems might reflect the combination of three timeframes in that measure compared to the single timeframe for SRE-5. While the relative performance of the two SRE measures had been noted in a few prior studies (e.g., Schuckit and Smith, 2012), a direct comparison of the two scores across multiple generations and across men and women had not been reported before. Hopefully, these results will encourage future investigators to include both measures in future studies.
