[Clarification Notice: A clarification for this article was reported online in on Aug 18 2022 (see record 2022-92429-001). In the original article, simultaneous linear regression analyses examined the role of sex and trait impulsivity differences in participants' unintoxicated level of behavioral impulsivity and sensitivity to alcohol-induced increases in disinhibition. High levels of trait impulsivity were associated with higher unintoxicated disinhibition; however, no sex difference in this relationship was obtained. Similarly, high attention impulsivity was associated with elevated unintoxicated disinhibition, but no sex difference in this relationship was obtained. It is likely that the inclusion of participants with ADHD in the original analyses disproportionately accounted for the sex differences initially obtained. This reanalysis suggests that behavioral disinhibition serves as a broad indicator of trait impulsivity in both men and women.] Objective: Higher trait impulsivity is associated with more impulsive responding on certain behavioral measures of disinhibition. Additionally, behavioral disinhibition is acutely elevated following alcohol consumption. The present study examined the possibility that trait impulsivity may predict individual differences in sensitivity to the disinhibiting effect of alcohol. Specifically, the present study tested the hypothesis that those with elevated trait impulsivity also experience heightened sensitivity to the disinhibiting effect of alcohol, which might further compound their tendency toward impulsive action.
