Effects Of Acute Alcohol Consumption On Executive Cognitive Functioning In Naturalistic Settings, Michael Lyvers, Juliette Tobias-Webb

Laboratory studies have demonstrated that acute alcohol intoxication can disrupt performance on neuropsychological tests of executive cognitive functioning such as the Wisconsin Card Sorting Test (WCST). However, the generalizability of such findings to typical self-regulated alcohol intake in social settings can be questioned. In the present study, 86 young adults were recruited at Australian bars to perform a computer version of the WCST. Participants displayed blood alcohol concentrations (BACs) across a range from 0 to 0.15%. Although self-report measures of typical alcohol consumption, impulsivity, and frontal lobe related everyday functioning were all intercorrelated in line with other recent findings, multiple …

Objective: To explore the factorial validity of the Toronto Alexithymia Scale (TAS-20) in an alcohol dependent population. Methods: Confirmatory factor analyses were conducted using structural equation modelling to evaluate the stability of the factor structure of the TAS-20. Based on previously reported factor structures, 1-factor, 2-factor and 3-factor models were examined, using maximum likelihood estimation. Results: Four of the five fit indices considered indicated a superior fit for the 3-factor model compared to the 2-factor and 1-factor models. Conclusion: This study demonstrates that the original 3-factor model of the TAS-20 was a more plausible fit to the data compared to …
