Etiological Development of Alcohol Use and Dependence From Adolescence to Midlife in a Longitudinal Community Study of Twins

Key Points

• Longitudinal study design tracking twins' alcohol use and dependence from adolescence into midlife.
• Comparative analysis of alcohol consumption patterns and dependence symptom counts over time.
• Alcohol use and dependence show distinct patterns in adolescence but converge in adulthood.
• Alcohol dependence measures do not effectively distinguish from alcohol consumption over time.
