[Clarification Notice: A clarification for this article was reported online inTo test this hypothesis, data from six studies were aggregated to comprise a sample of 190 young adults. Participants completed the Barratt Impulsiveness Scale-11 (BIS-11), and behavioral disinhibition was assessed using a cued go/no-go task following consumption of 0.65 g/kg alcohol and a placebo.Alcohol increased disinhibition overall, but higher impulsivity did not predict increased sensitivity to alcohol-induced disinhibition. In men, higher levels of trait impulsivity predicted heightened disinhibition in the unintoxicated state following placebo, but this relationship was not present in women.These findings suggest significant sex differences in the relationship between trait impulsivity and disinhibition. This sex difference may explain inconsistent research findings in studies assessing links between trait and behavioral measures of impulsivity. The data also point to trait impulsivity and sensitivity to alcohol-induced disinhibition as independent constructs. (PsycInfo Database Record (c) 2022 APA, all rights reserved). |
