abstract="OBJECTIVE: Research into cognitive performance during a hangover has produced  equivocal findings. This study investigated the reliability of inducing hangover  symptoms and effects on cognitive performance (including applied tasks) under  standardised conditions. <br><br>METHOD: Twenty-one participants (13 M; 24 ± 3 years)  completed two identical trials, involving alcohol consumption and an overnight  laboratory stay. Outcome measures included: hangover severity (a single-item  'Hangover' rating, and a sum of hangover symptoms [Overall Symptoms Score (OSS)]),  cognitive function (trail making test), simulated driving (standard deviation of  lateral position; lane crossings), and typing performance. Spearman's correlations  were used to assess reliability between trials for all participants, and when  ratings of 'Hangover' were consistent. <br><br>RESULTS: Participants demonstrated reliable  'Hangover' rating change from baseline (Trial A: 2.0 [2.0]; Trial B: 2.0 [2.0], rho  = 0.680, p = 0.001), but not for OSS (Trial A: 8.0 [12.0]; Trial B: 5.0 [9.0], rho =  0.309, p = 0.173). Performance in cognitive/applied tasks (range rho = 0.447-0771)  was consistent, except simulated driving (range rho = 0.035-0.272), however the  impairment was trivial. The subgroup analysis did not reveal substantial changes in  reliability. <br><br>CONCLUSION: A single 'Hangover' rating was a reliable way of  determining 'mild' to 'moderate' hangover severity. The present data could be used  to assist the methodological design of future hangover research.<p /> <p>Language: en</p>",
