Characterization Imaging Instruments in Alcoholics and Non-Alcoholics

Background: \- People with alcoholism have differences in their brains compared with healthy people. People who are dependent on alcohol also perform differently on behavioral tasks. Researchers want to find out more about these differences. They also want to see if these differences are related to DNA. Objective: \- To see if differences in brain structure relate to personality and behavior differences in people with and without alcohol dependence. Eligibility: \- Adults age 18 and older. Design: * Participants will visit the NIH Clinical Center once during the study. * Participants will be screened with a medical history, EKG, and physical exam. They will give blood and urine samples and undergo a psychiatric interview. * Participants will be asked about their alcohol drinking, to see if they have an alcohol use disorder. * Participants will play three computerized games. Some will play these games inside a magnetic resonance imaging (MRI) scanner. * MRI: strong magnetic field and radio waves take pictures of the brain. Participants lie on a table that slides in and out of a cylinder. They will be in the scanner for about 90 minutes. They may lie still for up to 20 minutes at a time. The scanner makes loud knocking noises. They will get earplugs.

Nicotinic Receptor Genetic Variation and Alcohol Reward

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....

Multi-Component Breath Alcohol Intervention Phase 3

This is the third stage of a three-stage, NIH-funded study to develop and test a multi-modal intervention concerning blood/breath alcohol concentration for young adults who drink heavily. The multimodal intervention will be made up of brief telehealth counseling and psychoeducation and use of three existing mobile technologies. The brief counseling/psychoeducation and mobile technologies provide personalized feedback regarding blood or breath alcohol content. The long-term goal of use of these mobile technologies will be to facilitate moderate drinking. However, the main goals of the proposed research are to learn more about feasibility of our procedures, perceived value of the technologies and ease of use from the research participants' points of view. In this third stage of the study, the investigators will conduct a randomized controlled trial building on the formative research conducted in Stages 1 and 2.

Developing and Testing an Online Intervention for Alcohol and Cannabis Misuse and Healthy Relationship Skills Among Young Adult Couples

The goal of this clinical trial is to develop and test a brief online intervention to reduce alcohol and cannabis misuse and improve healthy relationship skills among young adult couples. The main questions it aims to answer are: * Will the intervention be feasible and acceptable to young adult couples? * Will the intervention demonstrate initial efficacy in reducing risky substance use and increasing relationship functioning? Eligible couples will complete a virtual baseline session and be randomized to intervention condition (online intervention with 3-5 weeks of self-paced modules) or control condition (no intervention). Couples will complete two follow-up surveys (post-assessment - approximately 5 weeks after baseline, 3-month). Couples in the control condition will be offered the intervention after 3-month follow-up. Researchers will compare intervention and control groups to see if there there is a difference between the groups on substance misuse and relationship functioning at post-assessment and 3-month follow-up.

Text-Based Messaging Strategies for Preventing Subsequent Problematic Alcohol Use

Binge drinking, and its health/social consequences are substantial public health concerns, with a high prevalence in young adults, especially in the US military. Alcohol consumption in the military is very high and normative, but there is zero tolerance for alcohol-related legal trouble, and Air Force Airmen who experience this (e.g., DUI, sexual assault) typically receive a disciplinary action referred to as an Alcohol Related Incident (ARI). Brief Alcohol Interventions (BAIs) for alcohol misuse are effective in young adults who report binge drinking. Many BAI studies targeted young adults who drink hazardously; these individuals are typically not interested in abstaining but may try decreasing the amount or change the manner in which they drink in order to reduce harmful consequences. The investigators previously published the results of a BAI group-based intervention that reduced ARIs in over 150,000 Airmen on average by 16%. Since 2010, the BAI has been disseminated to most USAF Airmen in Technical Training. However, it is clear additional research is needed to enhance the efficacy of the intervention and reduce risks associated with problem drinking. One strategy to improve health outcomes is well-timed, tailored, and automated text messages. Building on the researchers' preliminary study where text messages reduced driving after drinking as well as total drinks consumed before driving, text messaging may be highly effective when sent at the precise time that Airmen gain access to alcohol (the first time they are allowed off base), a standard time for all Technical Trainees. One challenge to conducting alcohol research in the military is the lack of privileged communication. As a result, it is difficult to obtain valid self-reports due to a tendency to deny or minimize use. The investigators recently developed and validated a method for collecting anonymous data over time. This will be the first study in the military, as well as the first large scale, adequately powered trial, where intervention effects will be tracked out to a 6-month follow-up. The study's Specific Aims are to randomize approximately 3000 Airmen to either the current BAI versus the BAI+Text messages timed to occur before, during, and after Airmen have access to alcohol; and to evaluate the efficacy of the intervention at the end of training and 6 months post-training using repeated surveys with unique identifiers allowing researchers to match surveys while maintaining anonymity.

COVID-19 Pandemic Impact on Alcohol (PIA) - A Natural History Study

Background: The SARS-CoV-2 virus has caused a pandemic infection called COVID-19. It is a global threat to people, communities, and health systems. Researchers are concerned about the mental health effects of the pandemic. They want to learn more about how it is affecting people s alcohol use and problems, and how it may continue to affect them over time. Objective: To study the impact of the COVID-19 pandemic on alcohol use and consequences in individuals across the spectrum of alcohol use and those with alcohol use disorder. Eligibility: Participants who have been screened under the NIAAA Screening, Assessment and Management Protocol (14-AA-0181) Design: Participants will complete a baseline survey by phone. It will ask about alcohol use, alcohol dependence, and stress. It covers 2 time periods: the 12 months before the pandemic started and the time since it started. Participants will get an ID code and a link to an online survey. They will complete the online survey within a week of the phone survey. Participants will complete a series of online surveys over 24 months. For the first year, surveys will be completed weekly for the first 4 weeks, then biweekly for the next 8 weeks, and then every 1-2 months for the rest of the year. For the second year, surveys will be completed every 6 months. Surveys will cover the following topics: * Alcohol use and its consequences * Other substance use * Stress * Impact of the COVID-19 pandemic * Pain * Physical health * Sleep * Quality of life. Because the course of the pandemic may change, the frequency of the surveys may change. Participation lasts 2 years.

Alcohol Self-reporting During Pregnancy. AUTOQUEST Study.

The effects of alcohol consumption during pregnancy have been known for decades. However, alcohol consumption in pregnant women remains today a public health problem and its identification is primordial. During pregnancy, standardized self-reports such as T-ACE would help identify early women with high-risk alcohol consumption. T-ACE appears to be one of the most used during pregnancy but its diagnostic value is not objectively known. To evaluate the diagnostic value of T-ACE self-report in the detection of high-risk alcohol consumption during pregnancy, by comparison with the dosage of a biomarker in blood. Material and methods Multicentric diagnostic prospective study of 2425 pregnant women followed in 3 hospitals of North of France. The self-report will be offered to all women during their prenatal consultation in these 3 maternity clinics. When they returned their self-report to the medical practitioner, a unique blood test of phosphatidylethanol will be proposed to them for a period of one year. Made after informed consent, this dosage will be used as a gold standard of an alcohol consumption during the previous three weeks to establish the diagnostic value of T-ACE. An alcohol consumption will be considered " at high risk " if blood phosphatidylethanol is ≥ 20 µg/L. With a predictable 25% rejection rate and a positive 4% T-ACE frequency, the inclusion of 2425 patients should permit to estimate sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) of T-ACE with a satisfactory 95% confidence interval in this population. The evidence of a link between positive T-ACE and real high-risk alcohol consumption in pregnant women would objectively validate the use of this self-report during pregnancy. The T-ACE within the self-report (self-administered questionnaire) set up in these 3 maternity hospitals in the North of France is already a reference thanks to its several advantages to better identify psychosocial risk situations and especially high-risk alcohol consumption during pregnancy than medical history. If T-ACE appeared to be a sensitive and specific method for identifying high-risk alcohol use during pregnancy, it could be generalized in the follow-up of pregnant women in our country.

Improving Care for Unhealthy Alcohol Use in Primary Care

In order to improve the quality of alcohol-related care for those with unhealthy alcohol use, the current research will use an evidence-based implementation strategy, practice facilitation, at one VA primary care site to pilot test whether practice facilitation has the potential to improve the quality of primary care-based alcohol-related care . It is hypothesized that primary care providers who take part in the practice facilitation intervention will provide higher quality substance use care to Veterans with unhealthy alcohol use compared to care pre-practice facilitation (e.g., administer evidence-based brief counseling interventions at higher rates, prescribe alcohol use disorder pharmacotherapy at higher rates, increase referrals to specialty substance use disorder clinics).

Approach-Avoidance and Alcohol Challenge Study in PTSD

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.

Reducing Alcohol Exposed Pregnancies

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.

MPFC Theta Burst Stimulation as a Treatment Tool for Alcohol Use Disorder: Effects on Drinking and Incentive Salience

The purpose of this study is to develop transcranial magnetic stimulation (TMS), specifically TMS at a frequency known as theta burst stimulation (TBS), to see how it affects the brain and changes the brain's response to alcohol-related pictures. TMS and TBS are stimulation techniques that use magnetic pulses to temporarily excite specific brain areas in awake people (without the need for surgery, anesthetic, or other invasive procedures). TBS, which is a form of TMS, will be applied over the medial prefrontal cortex, (MPFC), which has been shown to be involved with drinking patterns and alcohol consumption. This study will test whether TBS can be used as an alternative tool to reduce the desire to use alcohol and reducing the brain's response to alcohol-related pictures.
