Influence of Shared Environments in Development of Alcohol Use Disorder: A Scoping Review

Abstract

Background: The influence of shared genetic vulnerability is well-known in the development of alcohol use disorder. However, there is a dearth of studies on shared environments. Hence, the present study aimed to ascertain the influence of shared environments in the development of alcohol use disorder. Aim: To examine the influence of adverse childhood experiences, parental bonding, and temperament in the development of alcohol use disorder. Methods: Preferred Reporting Items for Systematic reviews and Meta-Analysis extension for Scoping Reviews (PRISMA-ScR) guidelines were followed. Studies were identified through search engines such as PubMed, Embase, and Psych Info, CINAHL databases. Peer-reviewed articles in English published during 2000 - 2021 were included for the review. Results: About 47 articles were considered for the scoping review. Shared environmental factors such as adverse childhood experiences or childhood trauma within 18 years of life, novelty, adventure seeking, cyclothymia, and immediate need for gratification contribute to alcohol use disorder development. Positive parenting is associated with a lower incidence of AUD. Conclusion: Understanding the influence of shared environments and providing tailor-made psycho-social interventions would reduce the risk and prevent alcohol use disorder development..
