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

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 PsychInfo, 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..
