This study will test the reliability of a procedure for self-administering ethanol (alcohol) intravenously (through a vein), using a computer-assisted method. People ordinarily self-administer alcohol through drinking alcoholic beverages, but blood alcohol levels resulting from drinking vary greatly among individuals. For research on alcohol dependence and treatment, a tool for achieving precise blood levels is needed. In addition to testing this method of alcohol administration, the study will examine self-administration behavior and resulting breath alcohol concentration, the effects of alcohol on the participants, and differences between men and women in alcohol self-administration. Healthy normal volunteers between 21 and 45 years of age may be eligible for this study. Participants are assigned to one of two study groups. Group 1 undergoes three 7-hour study sessions and group 2 participates in two sessions, each of which includes the following procedures: * Breathalyzer and urine tests for alcohol and illicit drug use. * Urine pregnancy test for women. * Light lunch. * Questionnaire about health and recent drinking. Alcohol infusion: Subjects are seated in a comfortable chair and instructed on how to use a computer to give themselves a short infusion of alcohol through a catheter (plastic tube) that has been inserted into a vein in their the arm. Sensors are placed on their chest to monitor heart beat and their neck to record skin blood flow. At the start of the session, subjects complete questionnaires about any drug effects and urges to drink they may be feeling. They are trained on how to use the computer to administer alcohol and are then allowed to self-administer alcohol through the catheter any time they like, as long as their peak breath alcohol level does not exceed 0.1 g% (a level that would result from ingestion of 4 to 6 drinks in most people). If that point is reached, the computer automatically inactivates self-administration until the level is lowered again. Breathalyzer readings are taken every 15 to 30 minutes. Subjects may read, watch television or videos or listen to music during the sessions. Recovery: At the end of the 2.5 hours of self-administration, the catheter is removed and subjects can eat, read, watch television and relax in the clinic until their breath alcohol level falls below 0.02 g%, usually after 2.5 to 3 hours, when they can go home by taxi or with a pre-arranged designated driver. ...

The study evaluates the efficacy of 1 week of tDCS (5 sessions) placebo in reducing alcohol consumption within the 24 weeks following the treatment in non-abstinent patients with alcohol use disorders versus placebo.
NCT03956238
The present project integrates previous research on factors associated with alcohol-involved sexual assault, with research on how intoxication alters attention and social perceptions in ways that increase the risk of sexual aggression and victimization. Specifically, this project examines whether alcohol intoxication on the part of a male perpetrator impairs attentional capacity and leads to a narrowing of the perceptual field causing a dehumanizing perspective of women as sexual objects for men's pleasure rather than individuals with thoughts and feelings, thereby increasing the propensity for sexual aggression. The present research also examines whether women's responses to this sexual objectification from men interfere with risk perception in sexual situations, particularly when women are drinking, increasing the likelihood of sexual victimization.
NCT03001024
Responsible Beverage Service Training (RBS) has been shown to be effective and recent research by this research team has shown that online RBS training (WayToServe®) was more effective, particularly over time, than usual and customary (UC) RBS training by live trainers. However, one growing segment of alcohol servers and sellers has been neglected in RBS training efforts: Hispanic primarily Spanish-speaking servers in predominantly Spanish-speaking premises. This project will develop and test the first online RBS training for predominantly Spanish-speaking servers, WayToServe Español, which is culturally and linguistically appropriate and will fill a gap in evidence-based alcohol prevention interventions for this underserved population.
NCT00183170
The primary goal of the study is to assess the residual effects of heavy drinking on academic performance. The investigators will also explore whether these effects differ by family history of alcohol abuse and hangover symptoms, as well as compare males and females with respect to these effects. The primary hypothesis is that intoxication (0.10 g% blood alcohol concentration \[BAC\]) with an alcoholic beverage impairs next-day academic performance, as measured by scores on quizzes, standardized academic achievement tests, and standardized neurobehavioral assessments. The secondary hypothesis is that family-history-positive individuals will show a greater performance decrement the day after heavy drinking than family-history-negative individuals.
NCT00001673
This protocol has three purposes: (1) to evaluate subjects for inclusion or exclusion from other NIAAA protocols; (2) to provide a common set of descriptive information that will be available on all NIAAA research subjects; (3) to allow NIAAA medical and nursing staff to treat alcoholic patients for acute alcohol intoxication or alcohol withdrawal before requiring patients to consent to evaluation for participation in research studies. Information collected will include such items as psychiatric diagnoses, presence or absence of brain, liver or other organ damage, history of the amount of past alcohol consumption, other substance use and family history of alcoholism. This information will allow investigators to determine for which, if any, NIAAA research studies a subject is eligible. In order to avoid requiring intoxicated subjects to consent for procedures such as HIV testing, psychiatric interviews, and Magnetic Resonance Imaging (MRI) of the brain we will obtain consent from all alcoholic subjects in two phases, using two separate consent forms. The first consent form will express the subject's desire to be admitted to the NIAAA inpatient unit for the purpose of treatment for alcoholism and will authorize only medical evaluation and treatment for alcoholism and associated problems. After an alcoholic subject has been admitted to the inpatient unit and is judged to be no longer intoxicated or suffering from acute alcohol withdrawal he or she will be presented with the second consent which will describe the evaluation for participation in other NIAAA research studies. Non-alcoholic, healthy controls will sign only one consent form describing the data to be collected and evaluation for participation in other NIAAA research studies.
