The role of anxiety in predicting drinking behaviour

Area of Science:

• Clinical Psychology
• Psychopharmacology
• Addiction Medicine

Background:

• Alcohol use disorder is a significant public health concern.
• Previous research indicates age of onset and ondansetron treatment influence drinking behaviors.
• The role of anxiety reduction in treatment outcomes requires further elucidation.

Purpose of the Study:

• To determine if reduced anxiety predicts improved drinking outcomes in alcoholics.
• To assess if anxiety reduction's predictive power extends beyond age of onset and ondansetron treatment.
• To investigate the impact of anxiety changes on end-state drinking behavior.

Main Methods:

• A 2x4 factorial randomized clinical trial involving early and late-onset alcoholics.
• Participants received placebo or varying doses of ondansetron with weekly group cognitive behavioral therapy.
• Weighted least squares regression analyzed the influence of ondansetron dose, age of onset, pre-treatment drinking, and anxiety on drinking outcomes.

Main Results:

• Changes in anxiety level significantly predicted end-state drinking behavior.
• Decreased anxiety during treatment correlated with fewer drinks per day at the final visit.
• Anxiety reduction accounted for a significant proportion of variance in drinking outcomes.

Conclusions:

• Reduced anxiety is a significant predictor of improved drinking outcomes in alcoholics.
• Anxiety management may be a crucial therapeutic target in alcohol use disorder treatment.
• These findings add to the understanding of factors influencing treatment success beyond medication and onset age.
