Introduction and background

Understanding the intricate relationship between personality factors and alcohol use has become increasingly crucial in contemporary research. The interplay between an individual's psychological makeup and their propensity for alcohol consumption is complex, influencing the onset, progression, and outcomes of alcohol use disorders (AUDs). The significance of delving into the realm of personality factors lies in its potential to enhance our comprehension of the multifaceted nature of alcohol-related behaviors [1]. The exploration of personality factors in the context of alcohol use provides valuable insights into the predisposing factors that contribute to the initiation and maintenance of problematic drinking behaviors. Individuals vary widely in their responses to alcohol, and these variations are often rooted in diverse personality traits. Investigating these traits not only aids in identifying those at risk for alcohol-related issues but also informs targeted intervention and prevention strategies [2].

Understanding the role of personality factors can shed light on why specific individuals may be more prone to engage in risky drinking behaviors or develop AUDs. In contrast, others may exhibit more controlled patterns of alcohol consumption. This knowledge is essential for developing tailored prevention and treatment approaches that address the unique needs of individuals based on their personality profiles [3]. AUDs represent a spectrum of conditions characterized by problematic alcohol consumption, ranging from mild to severe. These disorders pose significant individual health risks and contribute to societal challenges, including impaired workplace productivity, increased healthcare costs, and social ramifications. The complexity of AUDs necessitates a comprehensive understanding that goes beyond mere biological or environmental perspectives, prompting researchers to investigate the role of personality factors in shaping these disorders [4].

A key personality factor, impulsivity, characterizes the tendency to act on immediate urges without considering potential consequences. This trait has demonstrated a significant and close association with alcohol use, marking it as an influential factor in understanding patterns of drinking behavior. High levels of impulsivity are consistently identified as a risk factor for problematic drinking and the development of AUDs. Individuals exhibiting impulsive tendencies may encounter challenges in inhibitory control, finding it difficult to resist the immediate gratification associated with alcohol consumption [7]. The intricate relationship between impulsivity and alcohol use unveils valuable insights into the cognitive processes that underlie decision-making related to drinking behaviors. Understanding how impulsivity contributes to alcohol use is crucial for the development of targeted interventions, as it addresses the specific challenges impulsive individuals face in regulating their behavior around alcohol. By exploring the nuances of this relationship, researchers and clinicians can refine prevention and treatment strategies that address the cognitive components of impulsivity, ultimately contributing to more effective approaches for mitigating the risk of problematic alcohol use in individuals characterized by this personality trait [8].

Neuroticism

Neuroticism, a personality trait characterized by emotional instability, anxiety, and a propensity to experience negative emotions, emerges as a significant factor in the realm of alcohol use and misuse. Individuals exhibiting high neuroticism scores often turn to alcohol as a coping mechanism, seeking relief from emotional distress and negative affective states. The association between neuroticism and alcohol-related behaviors underscores the intricate interplay between emotional well-being and patterns of alcohol consumption. To address this relationship, it becomes imperative to comprehend how neuroticism contributes to the development and maintenance of problematic drinking behaviors. Unraveling the link between neuroticism and alcohol use is essential for the design of interventions that delve into the emotional underpinnings of drinking, aiming to promote healthier coping mechanisms instead of alcohol reliance. By understanding the role of neuroticism, clinicians and researchers can tailor interventions that address the specific emotional vulnerabilities of individuals with high neuroticism scores, ultimately fostering strategies that diminish the risk of alcohol-related issues and contribute to overall emotional well-being [9].

Extroversion

Extroversion, a personality trait characterized by sociability, assertiveness, and a preference for social interaction, introduces a nuanced dynamic to the landscape of alcohol use. While extroverted individuals may exhibit a greater inclination toward engaging in social drinking, the relationship between extroversion and problematic alcohol use requires careful examination. The impact of extroversion on alcohol consumption patterns extends beyond mere social preferences, offering insights into the intricate social dynamics that shape drinking behaviors. Exploring this association provides a valuable lens through which to understand how extroversion may influence an individual's susceptibility to alcohol-related issues [10]. Extroverted individuals, drawn to social interactions and group settings, may find themselves in environments where alcohol is prevalent, potentially impacting their drinking behaviors. Additionally, the nuanced relationship between extroversion and problematic alcohol use suggests that peer influence and social context play integral roles. Studying the influence of extroversion on alcohol consumption not only deepens our understanding of the social determinants of drinking behaviors but also allows for the identification of specific risk factors associated with this personality trait. This knowledge is critical for informing preventive strategies that account for social dynamics, peer influence, and the unique vulnerabilities of extroverted individuals, ultimately contributing to more targeted interventions in mitigating the risk of problematic alcohol use within this specific personality profile [10].

Agreeableness

Agreeableness, identified by a propensity toward cooperation, trust, and interpersonal warmth, introduces a distinctive perspective on its potential influence on alcohol use, particularly within social relationships. Individuals characterized by high agreeableness may be less inclined to engage in risky drinking behaviors, as their cooperative and accommodating nature tends to foster responsible drinking in social settings. The relationship between agreeableness and alcohol use hinges on the interplay between this personality trait and social dynamics [11]. The cooperative and trusting nature of individuals high in agreeableness can contribute to the establishment of social norms that discourage excessive alcohol consumption. Investigating the role of agreeableness in alcohol use provides valuable insights into how certain personality traits shape the dynamics of social interactions, influencing drinking behaviors within social circles. This exploration contributes to a more comprehensive understanding of how personality factors intersect with social contexts, shedding light on the potential protective influence of agreeableness in mitigating the risk of problematic alcohol use. Recognizing the impact of agreeableness on alcohol-related behaviors is pivotal for tailoring preventive strategies and interventions that leverage the positive social dynamics associated with this personality trait, ultimately contributing to a more nuanced and practical approach to addressing alcohol use within different personality profiles [12].

Conscientiousness

Conscientiousness, defined by self-discipline, goal-directed behavior, and a commitment to rules, establishes a compelling and inverse relationship with alcohol use and misuse, and individuals characterized by high conscientiousness exhibit responsible and controlled drinking patterns, reflecting their disciplined approach to decision-making. In contrast, lower conscientiousness is correlated with an elevated risk of experiencing alcohol-related problems, suggesting a potential vulnerability to impulsive or less-regulated drinking behaviors. Exploring the influence of conscientiousness on drinking behaviors unveils valuable insights into the cognitive and behavioral mechanisms that underpin responsible alcohol consumption [13]. Highly conscientious individuals tend to prioritize self-regulation and goal-oriented decision-making, shaping their approach to alcohol in a controlled manner. Understanding this association is pivotal for designing prevention and intervention strategies tailored to individuals with varying levels of conscientiousness. Emphasizing self-regulation, goal-setting, and adherence to responsible drinking norms can be particularly effective in interventions targeting those with lower conscientiousness. By recognizing the protective nature of conscientiousness against problematic drinking, clinicians and researchers can develop strategies that harness these inherent traits, ultimately contributing to more effective approaches in preventing and addressing alcohol-related issues within diverse personality profiles [14].
