Deciphering the Role of Oxytocin in Motivation: an fMRI Study. Part II
Healthy ControlsAlcohol Use DisorderThe proposed study will investigate the effects of intranasal oxytocin administration on neural activity associated with social and non-social motivation.
Impulsivity and Alcohol Response
Alcohol Use Disorder (AUD)Subjective Response to Alcohol (SR)Impulsivity, a well-known risk factor predicting negative outcomes, refers broadly to a proclivity towards rapid action with a suboptimal regard for future consequences. Importantly, impulsivity is a multidimensional construct incorporating generalized and behavioral facets. However, underlying mechanisms linking facets of impulsivity to high-risk drinking remain uncertain. Such mechanisms, if uncovered, may be more appropriate intervention targets than impulsivity directly. Similar to impulsivity, subjective response to alcohol (SR), or individual differences in sensitivity to the pharmacologic effects of alcohol, is an established risk factor for alcohol use disorder. Specifically, experiencing heightened rewarding stimulation and dampened aversive sedation from alcohol are related to high-risk drinking. Theory and recent findings indicate SR and impulsivity may be related, suggesting SR may be a mechanism linking facets of impulsivity to high-risk drinking. However, findings linking impulsivity to SR were all from secondary data analyses and most studies reported on only a single measure of impulsivity. For these reasons, an original data collection using laboratory alcohol administration methods is needed to address which facets of impulsivity are related to SR among young adult drinkers and whether these effects manifest while blood alcohol concentrations are increasing or declining. This study will utilize a laboratory alcohol administration design to investigate whether distinct facets of impulsivity (i.e., generalized, choice, response) are related to subjective responses (i.e., stimulation and sedation) following alcohol administration.
Using Neuroeconomics to Characterize State-Based Increases and Decreases in Alcohol Value
Alcohol Use DisorderAlcohol DrinkingThis study uses techniques from an area of research known as neuroeconomics, which integrates concepts and methods from psychology, neuroscience, and economics to better understand how people make decisions and how these decisions are supported by the brain. One neuroeconomic concept that is especially relevant in the area of addictions is substance demand, or how consumption of a commodity (e.g., alcohol, tobacco, or drugs) is influenced by price and other factors. Previous studies have shown that alcohol demand is related to severity of alcohol misuse, drinking quantity/frequency, and treatment outcomes. In addition, we know that alcohol demand can also fluctuate in response to environmental cues such as alcohol-related stimuli or external contingencies such as important responsibilities the following day. These increase and decreases in consumption and value are clinically significant because they help us understand how people with alcohol use disorders are able to successfully or unsuccessfully modulate their drinking behaviors. This study is examining how the brain responds in these situations and whether these responses differ as a function of severity of alcohol misuse. This study will use functional magnetic resonance imaging (fMRI) to understand brain activity patterns associated with changes in the value of alcohol in the presence of alcohol-related beverage cues relative to neutral-related beverage cue. Participants will be non-treatment-seeking adult heavy drinkers who are recruited from the community to participate in an fMRI scan. During the scan, participants will make decisions about how many alcohol beverages they would consume (hypothetically) at various prices while their brain activity during those decisions is measured. The first experimental manipulation involves an in-scanner alcohol cue exposure task in which the drinking decisions will be made after viewing high-quality images of alcoholic (beer/wine/liquor) beverages or neutral (water/juice/soft drinks) beverages.

Brief Intervention and Fibroscan for Harmful Drinkers Presenting to the Emergency Department
Alcohol Use Disorder (AUD)The investigators plan to assess the feasibility of a randomised controlled trial of an innovative screening (Identification), Brief Intervention, Fibroscan and Self-Referral for Specialist Treatment (IBAFiRST) programme for high risk drinkers in the Emergency Department (ED). IBAFiRST extends existing screening and advice given to people with potential alcohol use disorders (AUD) in ED. Currently patients who drink heavily have brief advice and are asked to refer themselves to community specialist alcohol treatment services (ATS) after leaving ED. A Fibroscan is a safe, quick and reliable ultrasound test to see if there are signs of "stiffening" of the liver which can indicate early liver damage. It is recommended as a non-invasive test by the National Institute for Health and Care Excellence (NICE) but is not known to be used within EDs in the UK. The investigators wish to test whether giving the patients the results of this scan will make them more likely to self-refer to ATS. Currently take up rates of ATS are low in this population and too few people are seeking treatment to help them reduce their alcohol intake. Because so little is known about self-referral in ED the investigators are completing a feasibility study before seeking funding for a large scale randomised trial.
Identifying and Managing Alcohol-related Health Problems in General Practice
Alcohol-Related DisordersAlcohol Problem2 moreThe overall purpose of the proposed research is to increase patients' and general practitioners' (GPs') awareness of alcohol as a relevant factor for a wide variety of health problems in general practice, and enable earlier help and treatment. To achieve this, the investigators aim to test the feasibility of a pragmatic strategy for identification of alcohol-related health problems, and the feasibility of a web-based intervention between consultations, as a supplement to usual care in general practice.
Developing e-Covery, an App-based Intervention to Support Individuals With Co-occurring Problem...
Alcohol Use DisorderOpioid Use DisorderThis project aims to improve the health of individuals engaged in co-occurring alcohol and opioid use by supporting the maintenance of behavior change initiated in substance use treatment. Building on prior research, this study will entail a stage 1b pilot to test the feasibility and acceptability of an app-based intervention for individuals reporting co-occurring alcohol and opioid use. The intervention will involve modifying an app currently used in a research study to collect GPS information to send push notifications when individuals encounter self-identified place-based triggers. Thirty individuals completing substance use treatment will consent to use the app for a thirty-day pilot period and will complete assessments of intervention feasibility and acceptability. Using within-subject tests, the analysis will summarize participant responses to assessments and will compare the use of general messaging to place-specific messaging.
Records for Alcohol Care Enhancement
Alcohol Use Disorder (AUD)Unhealthy alcohol use (the spectrum from risky consumption through alcohol use disorder, AUD) is a leading cause of preventable death in the US (88,424 deaths annually costing $249 billion a year), and alcohol-related health harms (e.g. AUD itself, cirrhosis) are increasing. Despite high frequency of contacts with the medical system, most people with unhealthy alcohol use do not receive evidence-based interventions due to factors such as stigma, lack of knowledge, challenges with implementing and maintaining tool-based screening, time or prioritization constraints, and more. Electronic health records (EHRs), Best Practice Advisories (BPA) and registries are known and practical tools to improve management and care of chronic disease by aggregating information about the target population, and by assisting the clinician in reminders, decision support, and disease-specific care management. EHRs may help clinicians identify, assess, treat and monitor care when assisted by targeted staff support such as a clinical care manager (CCM) and population health manager (PHM). These support staff help to track outcomes of care and treatments, allowing for increased engagement with the population, and facilitation of care. The study team created a live database/registry of patients with unhealthy alcohol use in the BMC electronic health record (Epic), and updated Epic-based best practice advisories (BPA) and clinical decision support (CDS) (Epic Smart Set) for risky alcohol use and AUD. To improve recognition, management, and overall services provided to patients with AUD, this trial aims to test the impact of these EHR tools (the BPA, CDS, registry and registry-based reporting) for risky alcohol use and AUD by incorporating a population health manager (PHM) and clinical care manager (CCM) to augment reach and support to clinicians, and test the feasibility and effectiveness of leveraging EHRs and targeted supports to improve AUD care. A four-group randomized control trial will be implemented to determine which of four interventions is most effective at increasing rates of initiation and engagement in AUD treatment, as well as other clinical processes and outcomes. The trial will compare the use of the 1) BPA alone (only Epic-based clinician prompting and CDS), 2) BPA + PHM, 3) BPA + CCM, and 4) BPA + PHM + CCM, on the trials' primary, secondary, and exploratory outcomes. Trial results will be assessed by examining outcomes for patients on the clinician's panel.

Emotion Regulation Interventions for Preventing Collegiate Escalations in Drinking
Alcohol AbuseIn the most recent National Survey on Drug Use and Health (NSDUH), college aged respondents between 18 and 25 years old reported the highest alcohol use rates (over 58%) as well as the highest rates of binge drinking of any age group. High alcohol use/abuse in college students is associated with myriad negative consequences, including fatal and nonfatal injuries and overdoses, impaired academic and vocational performance, violence and other crime, legal problems, unintended pregnancies and sexually transmitted diseases, and social problems. The National Comorbidity Survey underscores that use initiated in this period is not just experimental and recreational but may have lasting effects on consumption trajectories: For the majority of adults diagnosed alcohol use disorders, onset occurred during emerging adulthood. During this stage of development, vast changes in emotion regulation (ER) take place, particularly age-related shifts in the strategies used to manage distress that may lead to alcohol use/abuse (i.e., emotion suppression, inhibitory control, and cognitive reappraisal. Substantial evidence suggests that deficits in ER are strongly related to patterns of alcohol use in young adults. In particular, deficits in the self regulation of discomfort and distress, called distress tolerance, predict alcohol use - specifically, motivation and urgency for use, escalations in consumption, and the development of dependence that may be indicative of alcohol use disorders. Emerging adults who turn to alcohol as a way of coping with distressing emotions are most at risk for heavy alcohol use into adulthood and more severe negative alcohol consequences. Given the variable effectiveness of existing approaches for reducing college students' alcohol use, The investigators contend that interventions may be differentially effective depending on individual characteristics. In particular, students with difficulties in managing distress and discomfort may benefit from more intensive interventions that promote effective ER compared to treatment as usual; further, other background characteristics may predict the efficacy and acceptability of each type of ER intervention. In this R34, investigators will test the acceptability/ feasibility and preliminary efficacy of two complementary interventions (Yoga and Distress Tolerance) on preventing alcohol use in a randomized controlled trial of 180 high-risk college students relative to treatment as usual. Investigators will assess participants' alcohol use (self-report and biomarker measures) and emotion regulation (ER) at baseline along with physiological discomfort sensitivity and psychosocial predictors of treatment efficacy over time, including a post-treatment follow-up. Study aims include: Test feasibility/acceptability of two ER interventions among high-risk emerging adults by documenting rates of recruitment, retention, adherence, and satisfaction. Examine trends in intervention acceptability based on baseline characteristics (i.e., associations between participant retention and participant-rated acceptability and age, gender, family characteristics/dynamics, and predispositions to discomfort tolerance). Test preliminary efficacy of the ER interventions on measures of ER and alcohol use. Hypothesis: Participants in both intervention groups will see greater improvements in ER and alcohol use outcomes compared to the TAU control group.
