The Roles of Alcohol Availability, Overserving, and Enforcement in Recreational and Social Settings on Alcohol Misuse and Harms: A Comparison of Australia and the United States.

Objective: To examine how alcohol availability, overserving, and enforcement in recreational and social settings are related to alcohol misuse and alcohol-impaired driving among young adults in Victoria, Australia and Washington State, United States.

Method: Longitudinal data came from 1,430 participants in Victoria (n = 757; 52% female) and Washington (n = 673; 53% female), surveyed in 2014 (age 25) and 2018 (age 29) from the International Youth Development Study, a population-based, cross-national study to examine factors influencing substance use. Path modeling tested associations between age 25 perceptions of the alcohol environment, age 25 social alcohol consumption, and age 31 alcohol-related harms.

Longitudinal associations between adult-supervised drinking during adolescence and alcohol misuse from ages 25-31 years: A comparison of Australia and the United States.

Prior studies suggest that adult supervised drinking in adolescence predicts greater adolescent alcohol misuse. Long-term follow up data examining how adult supervised drinking during adolescence relates to alcohol misuse in adulthood are lacking. Longitudinal data from the International Youth Development Study tested associations between adult supervised drinking during adolescence (ages 13-16; 2002-2004) and adult alcohol misuse (ages 25-31; 2014, 2018, 2020).
