Clinical Trial Summary

This study will provide the first rigorous integrative test of the hypothesis that rapid rises in estradiol (a female hormone) increase the rewarding and disinhibiting effects of alcohol and that such increased sensitivity correlates with increased alcohol use. Identification of the behavioral mechanisms by which estradiol surges can increase alcohol use would provide a critical advancement of neurobiological theory of alcohol abuse in women, an understudied area, as well as provide new directions for personalization of alcohol abuse treatment in women. In this study, naturally-cycling women will be examined daily over their menstrual cycle using an integrative combination of daily ecological assessments of hormone fluctuations and alcohol use along with strategically-timed laboratory tests of their acute sensitivity to the rewarding and disinhibiting effects of a controlled dose of alcohol.

Intervention

Drug:
Placebo
Participants will attend two identical laboratory sessions to test sensitivity to the rewarding and disinhibiting effects of a controlled dose of alcohol, once during the early follicular phase and once during the late follicular phase. The test battery consists of measures of rewarding effects and alcohol (or placebo) effects on disinhibition and impulsive choice. The placebo consists of 300 ml of lemon-flavored soda with a small amount (3 ml) of alcohol floated on top.
Alcohol
Participants will attend two identical laboratory sessions to test sensitivity to the rewarding and disinhibiting effects of a controlled dose of alcohol, once during the early follicular phase and once during the late follicular phase. The test battery consists of measures of rewarding effects and alcohol effects on disinhibition and impulsive choice. The alcohol dose consists of 0.60 g/kg absolute alcohol that produces a peak blood-alcohol concentration of 80 mg/dl. Doses will be mixed with a carbonated, non-caffeinated, lemon-flavored soda and consumed within 10 minutes.

Outcome

Type Measure Description Time frame Safety issue
Primary Attentional Bias (Early Follicular Phase) Attentional bias is measured by the visual dot-probe task and provides an implicit assessment of the rewarding properties of alcohol as indicated by the degree to which an acute dose of alcohol increases the drinker's attention to alcohol cues. 1 day
Primary Attentional Bias (Late Follicular Phase) Attentional bias is measured by the visual dot-probe task and provides an implicit assessment of the rewarding properties of alcohol as indicated by the degree to which an acute dose of alcohol increases the drinker's attention to alcohol cues. 1 day
Primary Disinhibition (Early Follicular Phase) Disinhibition wil be measured by the cued go/no-go task, which requires participants to respond quickly to go targets and inhibit responses to no-go targets. 1 day
Primary Disinhibition (Late Follicular Phase) Disinhibition wil be measured by the cued go/no-go task, which requires participants to respond quickly to go targets and inhibit responses to no-go targets. 1 day
