An Exploratory Factor Analysis of the Stimulant, Sedative, and Affective Responses to Alcohol.

This study extends upon the literature evaluating the biobehavioral effects of alcohol by examining a novel combination of SR to alcohol measures. This study demonstrates that the proposed low arousal positive domain, which loaded onto the tension reduction factor, provides novel information not captured by previous SR measures. Going forward, studies of alcohol's subjective effects should use this dimensional approach to reduce multiple comparisons across a wide range of scales and to build a literature grounded on the underlying structure of SR as a translational phenotype for AUD.
