Background: Consumption of alcohol is a persistent social issue which is escalated when alcohol is easily available to the adolescents. The big five personality traits are seen to be relevant in the use of alcohol among adolescents. Early use of alcohol is a robust cause in developing alcohol dependency in later stages of life. Purpose: The present study aims to understand the role of personality traits and age of initiation of alcohol use among adolescents. Methodology: Different databases like PubMed and Google Scholar were used to find research papers for this review paper. Past 16-year papers were considered for this study. Results: Researchers have shown that impulsivity, extraversion, sensation seeking, being less open to experiences, non-conscientiousness have a relationship with alcohol use among adolescents. Friends’ alcohol use, poor parent child relationship, childhood adversity, parents’ alcohol consumption and extreme temperament profile are seen to be significantly associated with early age onset for drinking. Conclusion: Personality traits and age have an impact on adolescents’ alcohol use. Considerable research has been done in the are of personality however, more attention needs to be focused on the age of initiation for using alcohol. This study will help in devising measures for adolescents at an early stage thereby preventing them from being dependent on alcohol.
