The Multiple, Distinct Ways that Personality Contributes to Alcohol Use Disorders

Area of Science:

• Psychology
• Psychiatry
• Addiction Research

Background:

• Personality traits are demonstrably associated with problematic alcohol involvement, including alcohol use disorders (AUDs).
• The precise mechanisms and causal pathways linking personality to alcohol use and related problems require further elucidation.
• Existing theoretical models offer explanations for the personality-AUD relationship, but a comprehensive understanding remains incomplete.

Purpose of the Study:

• To summarize and critically review existing theoretical models that explain the relationship between personality and alcohol use disorders (AUDs).
• To explore the causal pathways through which personality traits may influence risky drinking behaviors and the development of AUDs.
• To identify future research directions and potential frameworks for integrating diverse models of the personality-AUD association.

Main Methods:

• Literature review and synthesis of theoretical models.
• Critical analysis of proposed causal mechanisms linking personality traits to alcohol involvement.
• Discussion of empirical evidence supporting or refuting theoretical propositions.

Main Results:

• Several theoretical models posit causal links between specific personality traits and increased risk for alcohol use disorders (AUDs).
• These models often focus on constructs such as impulsivity, negative emotionality, and sensation-seeking as key mediators.
• The review highlights the complexity of the personality-AUD relationship, suggesting multifactorial influences.

Conclusions:

• Personality is a significant factor in the etiology of alcohol use disorders (AUDs).
• Understanding the theoretical underpinnings of this relationship is crucial for developing targeted prevention and intervention strategies.
• Future research should aim to integrate existing models and test them within comprehensive frameworks to advance the field.
