Drinking motives

OBJECTIVE: Existing binge drinking reduction interventions such as brief intervention and personalized normative feedback have shown modest impact. The purpose of this study was to evaluate the feasibility (recruitment and retention rates), acceptability, and preliminary efficacy testing of a short-term "know your numbers (KYN)" intervention on motivating young adults to reduce their engagement in binge drinking. METHOD: Young adults (N=94, mean age 21 years) with a history of binge drinking received a 4-week KYN intervention that included information about their U...

Alcohol use disorder extracts substantial personal, social and clinical costs, and continued intake despite negative consequences (compulsion-like consumption) can contribute strongly. Here we discuss lickometry, a simple method where lick times are determined across a session, while analysis across many aspects of licking can offer important insights into underlying psychological and action strategies, including their brain mechanisms. We first describe studies implicating anterior insula (AIC) and dorsal medial prefrontal cortex (dMPF) in compulsion-like responding for alcohol, then review work suggesting that AIC/ventral frontal cortex versus dMPF regulate different aspects of behavior (oral control and overall response strategy, versus moment-to-moment action organization)...

BACKGROUND: Plant-based diets are becoming more and more widespread among the Spanish population, progressively replacing the Mediterranean dietary pattern. Different studies have shown the motivations for adherence to these diets, and others have highlighted some health advantages and disadvantages. PURPOSE OF THE STUDY: Further studies are needed to define the socio-demographic determinants that influence the choice of a plant-based diet and to study the relationship that the choice of dietary pattern has on the health and lifestyle habits of the population...

We previously reported that mice with low neuronal pH drink more alcohol, demonstrating the importance of pH for alcohol reward and motivation. In this study, we tested whether systemic pH affects alcohol consumption and if so, whether it occurs by changing the alcohol reward. C57BL/6J mice were given NaHCO3 to raise their blood pH, and the animals' alcohol consumption was measured in the drinking-in-the-dark and two-bottle free choice paradigms. Alcohol consumption was also assessed after suppressing the bitterness of NaHCO3 with sucrose...

BACKGROUND: Access to safe water, sanitation, and hygiene (WASH) is the most basic need for mankind. Poor WASH practices are associated with various waterborne diseases, especially in developing countries such as India. The aim of the study was to assess WASH practices among residents of different slum settlements in a ward of Kolkata, identify the factors associated with WASH practice, and explore the barriers faced by the families and municipal staff in providing adequate WASH services to the community...

AIMS: This study aimed to compare reward, relief, and habit treatment-seeking individuals on recent drinking, alcohol use disorder (AUD) phenomenology, and mood. The second aim of the study was to evaluate the predictive validity of reward, relief, and habit profiles. METHOD: Treatment-seeking individuals with an AUD (n = 169) were recruited to participate in a medication trial for AUD (NCT03594435). Reward, relief, and habit drinking groups were assessed using the UCLA Reward Relief Habit Drinking Scale...

BACKGROUND AND AIMS: Alcohol use and anxiety often co-occur, causing increased severity impairment. This protocol describes a randomized controlled trial (RCT) that aims to test the efficacy and cost-effectiveness of a web-based, self-guided alcohol and anxiety-focused program, compared with a web-based brief alcohol-focused program, for young adults who drink at hazardous levels and experience anxiety. It will also test moderators and mechanisms of change underlying the intervention effects...

BACKGROUND AND OBJECTIVES: Experiencing sexism is related to more alcohol-related problems, presumably via drinking to cope with negative affect associated with experiencing sexism. Yet no known studies have directly tested whether the relation of sexism to alcohol problems occurs via relevant negative emotions and drinking to cope with negative emotions. Given that sexism is a type of negative evaluation, social anxiety may be one type of negative affect that plays a role in sexism's relation with drinking behaviors...

BACKGROUND: As the return to alcohol use in individuals with alcohol use disorder (AUD) is common during treatment and recovery, it is important that abstinence motivation is maintained after such critical incidences. Our study aims to explore how individuals with AUD participating in an app-based intervention with telephone coaching after inpatient treatment perceived their abstinence motivation after the return to alcohol use, whether their app use behavior was affected and to identify helpful factors to maintain abstinence motivation...

Reports the retraction of "Event-level risk for negative alcohol consequences in emerging adults: The role of affect, motivation, and context" by Jack T. Waddell, Scott E. King, Sarah A.

Machine learning algorithms hold promise for developing precision medicine approaches to addiction treatment yet have been used sparingly to identify predictors of alcohol-related problems. Recursive partitioning, a machine learning algorithm, can identify salient predictors and clinical cut points that can guide treatment. This study aimed to identify predictors and cut points of alcohol-related problems and to examine result stability in two separate, large data sets of college student drinkers ( n = 5,090 and 2,808)...

BACKGROUND: Digital interventions, including apps and websites, can be effective for reducing alcohol consumption. However, many are not evidence- or theory-informed and have not been evaluated. We tested the effectiveness of the Drink Less app for reducing alcohol consumption compared with usual digital care in the UK. METHODS: In this two-arm, parallel group, double-blind, randomised controlled trial, we enrolled increasing-and-higher-risk drinkers (AUDIT ≥ 8) in the UK, who were motivated to reduce their alcohol consumption and willing to use a digital intervention to do so, via online methods...

AIM: Participating in a drinking game (DG) is common practice among university students and can increase students' risk for heavy drinking. Given the theoretical link between motivations to drink and alcohol use, careful consideration should be given to students' motivations to play DGs. In this study, we examined the factor structure, internal consistency, and concurrent validity of a revised version of the motives for playing drinking games (MPDG) scale, the MPDG-33. METHODS: University students (n = 3345, Mage = 19...

BACKGROUND: Prior studies indicate that neuroactive steroids mediate some of alcohol's effects. Dutasteride, widely used to treat benign prostatic hypertrophy, is an inhibitor of 5-alpha reductase enzymes, which play a central role in the production of 5α-reduced neuroactive steroids. The purpose of this study was to test dutasteride's tolerability and efficacy for reducing drinking. METHODS: Men (n = 142) with heavy drinking (>24 drinks per week) and a goal to either stop or reduce drinking to nonhazardous levels were randomized to placebo or 1 mg dutasteride daily for 12 weeks...

BACKGROUND: The majority of adults suffering from alcohol use disorders (AUD) do not receive treatment. To address this gap in care, we must develop new models to increase identification, engagement and delivery of accessible and effective treatment. This paper describes the protocol for a randomized controlled trial (RCT) testing a novel telehealth treatment model for primary care patients with untreated AUD. METHODS: We aim to recruit 300 adults across 2 healthcare systems for this two-arm RCT...

Chronic ethanol exposure often triggers neuroinflammation in the brain's reward system, potentially promoting the drive for ethanol consumption. A main marker of neuroinflammation is the microglia-derived monocyte chemoattractant protein 1 (MCP1) in animal models of alcohol use disorder in which ethanol is forcefully given. However, there are conflicting findings on whether MCP1 is elevated when ethanol is taken voluntarily, which challenges its key role in promoting motivation for ethanol consumption. Here, we studied MCP1 mRNA levels in areas implicated in consumption motivation-specifically, the prefrontal cortex, hippocampus, and striatum-as well as in the cerebellum, a brain area highly sensitive to ethanol, of C57BL/6 mice subjected to intermittent and voluntary ethanol consumption for two months...

Reinforcement learning (RL) is a theoretical framework that describes how agents learn to select options that maximize rewards and minimize punishments over time. We often make choices, however, to obtain symbolic reinforcers (e.g. money, points) that are later exchanged for primary reinforcers (e.g. food, drink). Although symbolic reinforcers are ubiquitous in our daily lives, widely used in laboratory tasks because they can be motivating, mechanisms by which they become motivating are less understood. In the present study, we examined how monkeys learn to make choices that maximize fluid rewards through reinforcement with tokens...

Individuals with posttraumatic stress disorder (PTSD) often engage in harmful alcohol use. These co-occurring conditions are associated with negative health consequences and disability. PTSD and harmful drinking are typically experienced as closely related-thus treatments that target both simultaneously are preferred by patients. Many individuals with PTSD and harmful alcohol use receive primary care services but encounter treatment barriers in engaging in specialty mental health and substance use services...

The present study aimed at exploring the combined effect of risk of eating disorders (ED), alcohol use, physical activity, and social and psychological traits in Food and Alcohol Disturbance (FAD) behaviors. Nine-hundred and seventy-six college students were included in the study. They were then divided into two groups based on the Compensatory Eating and Behaviors in Response to Alcohol Consumption Scale (CEBRACS): students with a FAD positive score and student with a FAD negative score. Both groups of participants were compared on the risk of ED, alcohol and physical activity variables, as well as social and psychological dimensions...

BACKGROUND: Drinking identity (the extent to which one links the self with drinking alcohol) is a unique risk factor for college students' hazardous drinking that is not directly targeted by existing interventions. We conducted a study that aimed to decrease drinking identity among college students with hazardous drinking. We adapted a writing task about the future self and tested whether three writing sessions could decrease drinking identity and change drinking. We also investigated whether two additional factors (writing perspective and inclusion of participants' social networks) would enhance task impact...
