Why the study?
Does perceived intoxication or actual BAC better predict performance impairment after alcohol consumption in adults aged 21 to 40?
Does perceived intoxication or actual BAC better predict performance impairment after alcohol consumption in adults aged 21 to 40?
Perceived intoxication may be a better indicator of acute performance impairment than actual blood alcohol concentration.
Perceived intoxication may better flag impairment risk than BAC; leaves open real-world applicability and needs prospective validation.
The purpose of this study was to report the relationship among perceived intoxication, performance impairment, and actual blood alcohol concentration (BAC) levels. Fifteen subjects, aged 21 to 40, completed both single- and double-dose sessions of alcohol consumption. BACs, reaction and anticipation time, and perceived intoxication data were collected during both sessions. Analysis of data showed that perceived intoxication was significantly related to performance impairment, but the actual BAC was not.
