In this study, the investigators aim to capture inter- and intra-brain mechanisms underlying alcohol reward in novel social context.
NCT03535129
Background: Problem drinking affects nearly half the people who drink alcohol. Drinking alcohol affects a person's social behavior and brain structure, but researchers don't have a good understanding of how. They want to test a technique called neurofeedback to learn more about how to treat problem drinking. Objectives: * To study what happens in the brains of people who drink alcohol when they look at pictures of social things and of alcohol. * To learn if people can control brain activity in a magnetic resonance imaging (MRI) scanner and if this helps people with drinking. Eligibility: * Adults ages 21 to 65 who have an alcohol use disorder. * Healthy volunteers ages 21 to 65 Design: Participants will be screened with * Physical exam * Medical history * Blood, urine, and heart tests * Mental health interview * Questions about their alcohol drinking. At each session, participants will have: * A urine test for drugs and pregnancy. If they test positive, they cannot participate. * A breath alcohol test and assessment for alcohol withdrawal. Participants will complete surveys, talk to researchers about behaviors, and play games. Participants will have MRI brain scans. The scanner is a metal cylinder in a strong magnetic field. They will lie on a table that slides in and out of the scanner for 1-2 hours. Participants will do tasks in the scanner: * They will look at pictures, sometimes of alcohol. * They will try to hit a goal. Some participants will get feedback during this task. They will see how their brain activity changes or how someone else's changes. Participants may have follow-up phone questions at least 3 times over about 6 months.

The purpose of this research study is to understand people's alcohol use in public places and their risks for harm. The overall goal of this study is to test the effects of subsidized ridesharing as an intervention to reduce self-reported alcohol-impaired driving, along with alcohol consumption and changes to mobility.
NCT06002633
Individuals with posttraumatic stress disorder (PTSD) have greater prevalence of alcohol use disorders (AUDs), with this comorbidity associated with worse illness outcomes, yet there remains limited mechanistic understanding of how PTSD confers risk for AUD. Understanding risk factors that associate with and predict the development of AUDs in PTSD could inform interventions and prevention efforts to reduce the rate of this comorbidity and improve outcomes of both disorders. Identifying predictors of risk requires longitudinal studies in PTSD aimed at capturing the mechanisms leading to the emergence of AUDs. There is growing evidence PTSD is related to biased decision-making during approach-avoidance conflict. Alcohol is also suggested to alter approach-avoidance decision-making. AUDs and acute alcohol intoxication is associated with a bias to seek out reward despite the possibility of threat (e.g., contributing to relapse following alcohol cue exposure and risky behavior during intoxication respectively). Alcohol-induced changes in approach-avoidance decision-making have not been investigated in the context of PTSD, but emerging data support the investigators' hypothesis that an interaction between alcohol and approach-avoidance conflict in PTSD may occur and contribute to risk for alcohol misuse and development of alcohol problems. No current data, cross-sectional or longitudinal, have tested the role of alcohol-induced changes in approach-avoidance conflict as a mechanism of risk for AUD among individuals with PTSD. To address this gap, the investigators propose to leverage the group's expertise in placebo-controlled alcohol administration procedures, longitudinal modeling, functional neuroimaging, and computational neuroscience approaches to investigate the effects of acute alcohol on approach-avoidance decision-making and mediating changes in multivariate neurocircuitry patterns in limbic, striatal, and salience networks.
NCT03294460
Background: People with the brain disease AUD (alcohol use disorder) have a serious problem with drinking. Researchers want to study how different people react to alcohol, and how genes affect this. They will focus on a nicotine receptor gene that may increase a person s AUD risk. Objectives: To see if people with variations of a nicotine receptor gene take alcohol differently and have different brain responses to alcohol cues. Eligibility: Healthy adults ages 21 - 60. This study includes smokers and non-smokers. Design: Participation will be based on evaluation under the NIAAA natural history protocol (14-AA-0181) or a screening visit under this protocol. Participants will have two 9-hour visits. They must have no alcohol or non-prescription drugs before all visits and no food or drink before the first visit. At every visit, participants will: * Get a light meal * Have breath and urine tests * Get taxi rides there and back At visits 1, participants will: * Have a thin plastic tube inserted in an arm and connected to a pump for alcohol infusion. * Have sensors on their chest to monitor heart rate. * Sit in a chair for 2.5 hours and get alcohol by pushing a button. Their breath alcohol level will be monitored. * Answer questions about mood and effects of alcohol * Give blood samples * Relax at the clinic while their breath alcohol level drops At visit 2, participants will: * Answer questions and do computer tests * Have an alcoholic drink and a snack * Have a magnetic resonance imaging (MRI) scan. They will lie in a machine that takes pictures of the brain. They will do computer tasks. * Have another drink and snack * Relax until their alcohol level drops Participants will have a follow-up call after each visit.
NCT05766761
The goal of this clinical trial is to compare an active intervention versus a standard of care control in reducing alcohol use among pregnant women. The main questions it aims to answer are whether a motivational intervention can: 1. increase the proportion of women detected with a laboratory-confirmed negative phosphatidylethanol (PEth) test during pregnancy, and 2. reduce the proportion of adverse birth outcomes among infants. Participants will be offered (1) a self-paced computer-delivered alcohol reduction intervention to enhance knowledge, norms, and motivation for alcohol reduction and (2) a nurse-delivered component to reinforce the computer-delivered content and address women's questions. Both components are theory-driven, based on Motivational Enhancement Theory (MET), and use motivational strategies to promote alcohol reduction.
NCT05414344
The current proposal aims to enhance a mobile-delivered brief intervention for young adults with heavy alcohol use and interpersonal trauma by including adaptive coping strategies for managing trauma-related distress and using peer coaches after delivery of the intervention to maintain treatment gains. Individuals will be randomized to a modified brief intervention incorporating with peer coaches, a standard brief intervention, or assessment only. Participants will be followed up at 3 and 6 months post intervention. The investigators hypothesize that the trauma-informed and peer-supported brief intervention (TIPS-BI) will show low levels of dropout, will be perceived positively by participants, and will result in greater reductions in alcohol use compared to a standard brief intervention and assessment only.

Alcohol misuse and related risky sexual behaviors are significant health concerns for college students. Two-thirds of students are current drinkers, at least 1 in 3 report past month heavy episodic drinking (5+ drinks in a row), and 1 in 10 report high intensity drinking (10+ drinks in a row). Increased student alcohol use and heavy drinking are linked to increased sexual activity and related risky behaviors (e.g., unprotected sex, sex with casual partners). This puts students at risk for negative health outcomes (e.g., STIs - sexually transmitted infections) and is also a pathway to sexual victimization and escalated drinking. The first few weeks of college, known as the 'red zone,' provide an opportunity to intervene at time when these behaviors increase. However, most prevention programs for college students tend to focus on student alcohol use and have little to no integration of content on the relationship between alcohol use and risky sexual behaviors. This is an important gap in the literature and a priority area for NIAAA. The research team established the short-term efficacy of a personalized feedback intervention (PFI), a gold standard intervention approach, with integrated content on alcohol and risky sexual behaviors. In this study, we propose to extend our integrated PFI to include a cross-tailored dynamic feedback (CDF) component. The CDF component will use technology to incorporate daily assessments of student behavior and provide students with dynamic weekly feedback over 12 weeks. The goal is to increase the effectiveness of the integrated PFI and to create a program that is easily implemented on college campuses.

Suicide is a high priority public health problem and an increasingly prevalent alcohol-related consequence. One-third of people who die by suicide consume alcohol at hazardous rates in the year preceding death. Most people in an acute suicide crisis who present for treatment are admitted to acute psychiatric hospitalization. Yet, the 30-day period following discharge from hospitalization is by far the riskiest period for another suicide crisis. The specific aim for this project is to use a successive cohort design to iteratively develop an intervention called mHealth-supported Skills Training for Alcohol-Related Suicidality (mSTARS). The study team will adapt and iteratively refine a cognitive-behavioral skills training intervention in emotion regulation to be administered in an acute care setting and paired with a post-discharge mHealth app that encourages application of these skills to real life. Two cohorts of five participants each will be enrolled in the project. Participants will complete mSTARS, an intervention that combines inpatient skills training and the mHealth telephone app. Upon completion of the 30-day period, participants will complete self-report measures and participate in an interview designed to evaluate their experience with the mSTARS intervention.
NCT00278785
The underlying hypothesis that providing brief interventions to individuals who engage in potentially harmful patterns of alcohol use will alter their drinking behavior and therefore avoid negative consequences. Specifically, this study aims to determine if brief interventions will: 1. Reduce the number of re-admissions and deaths due to injuries associated with alcohol consumption 2. Reduce the number of driving under the influence (DUI) arrests 3. Reduce harmful drinking behavior
NCT05551754
This is a single blinded, randomized trial to evaluate the immediate subjective and objective effects of alcohol after a dose ketone supplement compared to a placebo in 10 health volunteers. Subjects will complete 2 lab visits where they consume a dose of alcohol (based on weight), to bring their breath alcohol concentration to about 0.050%. Participants will randomly receive ketone supplement at one lab and the placebo at the next lab.
NCT06513819
The focus of this pilot will be on falls and neurocognitive symptoms, and the impact of alcohol, cannabis use, and medications on these outcomes. The rationale is that alcohol use at any level may interact with neurocognitively active medications, alcohol, and cannabis use leading to falls and impaired cognition.
NCT07332429
The goal of this clinical trial is to learn if Alcovit® (zeolite clinoptilolite) works to reduce blood alcohol concentration in healthy adults aged 18-70 years who are occasional or moderate alcohol consumers. It will also learn about the safety and tolerability of Alcovit®. The main questions it aims to answer are: * Does Alcovit® reduce blood alcohol concentration when administered before or after standardized alcoholic beverage consumption compared to placebo? * What is the rate of alcohol elimination from the blood (mg/dL/hour) in participants taking Alcovit® compared to placebo? * Is Alcovit® well tolerated when administered before or after alcohol consumption? Researchers will compare Alcovit® administered before alcohol consumption, Alcovit® administered after alcohol consumption, placebo administered before alcohol consumption, and placebo administered after alcohol consumption to see if Alcovit® effectively reduces blood alcohol levels. Participants will: * Consume a standardized alcoholic beverage under controlled conditions; * Take Alcovit® or a placebo either 2-3 minutes before or after (within 5 minutes) alcohol consumption; * Have blood samples collected at baseline (30 minutes before), and at 20, 40, and 60 minutes after alcohol consumption to measure blood alcohol concentration; * Complete breathalyzer (etilometer) measurements at the same time points; * Answer questionnaire to assess alcohol hangover severity; * Have safety blood tests performed to monitor liver and kidney function.

NCT03517878
The purpose of this early Phase 2 comparison trial is to evaluate the impact of community health worker (CHW) home visitors on pregnant women and their children in a rural setting in the rural Eastern Cape of South Africa. The intervention provided by the CHWs targets underweight children, mothers living with HIV (MLH), mothers using alcohol, and depressed mothers with the goal of supporting pregnant women to improve birth outcomes, decrease the number of children born with a low birthweight, and develop child caretaking skills over time. UCLA has identified and matched four areas surrounding primary health care clinics: two intervention areas in which this CHW program has been running for one year, and two control areas without the program. Mothers in the research area are followed for one year after giving birth.

Alcohol use disorders (AUDs) affect up to 60% of individuals with bipolar disorder during their lifetime-a rate 3 to 5 times higher than what occurs in the general population. The mechanisms that contribute to elevated rates of comorbidity are not known. Early identification in individuals with bipolar disorder who are at risk for AUDs could inform novel intervention strategies and improve life-long outcomes. The primary objective of this protocol is to use alcohol administration procedures and functional MRI techniques to investigate subjective response to alcohol, compared to placebo, and relationship with functional responses of, and connectivity among, brain regions in ventral prefrontal emotional networks in young adults with bipolar disorder and healthy comparison young adults. Baseline clinical and structural MRI assessments will be completed in 30 bipolar and 30 healthy young adults (21-26 years of age, 50% women). Then, following standard beverage administration procedures, participants will complete within-person, counter-balanced, fMRI scans and complete measures of subjective response to alcohol while under the influence of alcohol or placebo. Specifically, individual differences in the experience of stimulating, sedative, and anxiolytic effects of alcohol (measured with self-report surveys) and individual differences in neural responses to alcohol within ventral prefrontal emotional networks will be investigated and differences in bipolar disorder compared to healthy participants assessed. Functional MRI scans during a continuous performance task with emotional and neutral distractors (CPT-END) and at rest will be collected while under the influence of alcohol and placebo and compared. Experience of stimulating, sedative, and anxiolytic effects of alcohol from self-report survey data and neural responses to emotional stimuli while under the influence of alcohol compared to placebo will be the primary data outcomes assessed. Additionally, associations between subjective and neural response to alcohol and drinking patterns will be explored (secondary outcomes). The primary endpoint of the study will be after completion of both alcohol and placebo beverage conditions.
NCT06576674
The goal of this pilot study is to identify the role of satiety on responses to alcohol drinking using human subject laboratory methods. Satiety will be manipulated over two sessions using a dietary supplement (fiber+green tea) or a calorically matched placebo. Responses to an acute alcohol challenge are measured.
NCT04895033
This study is using functional magnetic resonance imaging (fMRI) to examine brain activity associated with making decisions about drinking alcohol in everyday situations, some of which may involve important activities happening the next day. The secondary aims are to determine whether severity of alcohol-related problems is related to brain activity and alcohol choices and to examine how different areas of the brain interact in connected networks.
NCT06129487
The goal of this study is to determine the effectiveness of pictorial warning labels (PWLs) featuring narrative (vs. non-narrative) content in communicating the cancer risk of alcohol. Participants will be randomized to view either three narrative or non-narrative PWLs. Key outcome variables include visual attention, message reactance, risk perceptions, and intentions to reduce and stop drinking.
NCT06587139
The purpose of this project is to develop and evaluate an online mentoring and skill-building program for transgender and/or gender minority youth (TGMY) ages 14 to 18, the Teen Connection Project (TCP). The TCP includes seven 90-minute sessions facilitated by transgender and/or gender minority (TGM) adults (who are also mentors). TGMY will be paired with a TGM adult mentor, based on their shared interests. Mentors and mentees will participate together in each session along with other mentors and mentees. Mentors will direct activities and discussion to promote TGMY social-emotional skills. The TCP sessions will include one-on-one mentor-mentee break-out sessions.
