Psychological and behavioural factors that contribute to alcohol consumption and alcohol hangover occurrence and severity in Australia

Alcohol is frequently consumed and present in many aspects of daily life, yet excessive consumption can result in alcohol hangovers. This thesis implies that less favourable perceptions around alcohol abstinence continue to exist and individuals' own alcohol use should be considered. Estimated blood alcohol concentration (eBAC) was calculated with two methods, with both methods demonstrating decreasing hangover resistance with increasing eBACs. Several psychological factors are significantly associated with hangover severity. Higher levels of mental resilience are associated with decreased hangover severity, whereas lower mood and high scores on avoidant coping strategies are associated with increased hangover severity.
