Motivation for IV Alcohol Self-Administration in Humans
Sponsor: University of California, Los Angeles
Summary
The goal of this translational study is to understand different reasons why people between the ages of 21 and 65 with alcohol use disorder are motivated to self-administer alcohol. The main questions it aims to answer are: * How does a person's desire for a reward affect their motivation to self-administer alcohol? * How does a person's emotions affect their motivation to self-administer alcohol? * How does a person's cognitive functioning affect their motivation to self-administer alcohol? Participants will be asked to complete questionnaires about their mood, habits, and functioning and will complete an IV alcohol administration that will include pressing a button to receive additional doses of IV alcohol.

Interventions
Intravenous Alcohol
Participants will receive intravenous alcohol (6% ethanol v/v in saline; obtained from the Ronald Reagan UCLA Medical Center Investigational Drug Service) over the course of an alcohol challenge. During the challenge, participants will be administered alcohol designed to reach target BrACs of 20, 40, and 60 mg%, each over 15 min. After reaching the last target BrAC (0.06 g/dl) participants will complete a self-administration (SA) paradigm. Participants will be invited to work (button press) for alcohol according to a log-linear progressive ratio schedule.
