Alcohol use disorder is a major problem worldwide and can result in a number of significant physical, social and economic consequences. Specifically when comparing the prevalence of alcohol use disorders in the United States and Spain, it is much higher in the United States, at 13.9% compared with 1.5% in Spain. While there are a number of factors that contribute to a person’s risk, this thesis focuses on possible cultural explanations for these differences. After analyzing current literature surrounding alcohol trends and differing cultures in the US and Spain, the differences could be attributable to the dry drinking culture in the US, and the culture surrounding university - living and college towns in the US. The findings of this study suggest that culture, norms and attitudes surrounding drinking have a large impact on alcohol use disorder, and the US could benefit from implementing strategies to change these norms and attitudes surrounding alcohol, as well as train healthcare providers to have effective, brief counseling conversations.
