The relationship between anxiety disorders and alcohol use: predictors and predictive modeling

Anxiety disorders (AD) and risky alcohol use are often interrelated, creating a vicious cycle that reduces treatment efficacy and patients’ quality of life. A study involving 120 AD patients identified key predictors of risky alcohol consumption. Patients with generalized anxiety disorder were found to have a 2.3 times higher risk of alcohol abuse compared to those with episodic anxiety. Key risk factors included high levels of neuroticism, emotional discomfort, phobic reactions, and a lack of adaptive coping strategies. Using CHAID analysis and logistic regression, researchers developed a predictive model with high accuracy (AuROC=0.937), which takes into account both clinical and individual psychological characteristics. The results highlight the importance of considering the type of anxiety and associated psychological traits when designing prevention programs. For patients with generalized anxiety, the focus should be on reducing emotional discomfort and phobic reactions, while for those with episodic anxiety, developing emotional support-seeking skills and addressing neuroticism are crucial. The findings align with current understanding of the relationship between anxiety disorders and alcohol use, offering practical recommendations for clinical practice. The study contributes to a deeper understanding of the mechanisms underlying the transition from moderate to risky alcohol use in patients with anxiety disorders and suggests directions for further research, including the role of coping strategies and the development of comprehensive prevention models.
