What this trial studies

This study aims to explore the motivations behind alcohol self-administration in individuals aged 21 to 65 with alcohol use disorder. Participants will undergo intravenous alcohol administration followed by a progressive ratio self-administration task, where they will press a button to receive doses of alcohol. The study will assess how factors such as desire for reward, emotions, and cognitive functioning influence their motivation to consume alcohol. Additionally, participants will complete questionnaires and provide blood samples for biomarker analysis related to stress and inflammation.

Who should consider this trial

Good fit: Ideal candidates are adults aged 21 to 65 who have a current diagnosis of alcohol use disorder and have consumed alcohol in the past 30 days.

Not a fit: Patients who are currently seeking treatment for alcohol use or have a history of treatment in the past 30 days may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved understanding and treatment strategies for individuals with alcohol use disorder.

How similar studies have performed: Other studies have explored motivations for alcohol use, but this specific approach combining intravenous administration and progressive ratio self-administration is relatively novel.
