The effects of alcohol on emotion in social drinkers

Taking pleasure seriously: Should alcohol research say more about fun?

BACKGROUND

This paper invites discussion on whether pleasure should receive more attention in public health-oriented research on alcohol. While there is a history of sociological and anthropological literature exploring alcohol and pleasure, this is much less common in public health-oriented alcohol research, and associated advocacy.

ARGUMENT

We propose three broad reasons why more extensive engagement with issues of pleasure may be important for public health-oriented research. The first is epistemological: because overlooking pleasure risks leaving a gap in knowledge of a key component of, and motive for, drinking. The second is ethical: because the prioritisation of long-term health over shorter-term pleasures is not uncontested, and needs to be explicitly justified. The third is pragmatic: because ceding the discourse on pleasure to other actors (including commercial ones) risks undermining effective engagement with target populations.

CONCLUSIONS

There is strong case for more attention to pleasure in public health-oriented alcohol research. Key to this is the further development of interdisciplinary perspectives and mixed-methods research. This brings both conceptual and methodological challenges, many of which remain unresolved; however, bringing these issues to the surface may enable greater clarity on both normative principles (including arguments against research engaging with pleasure) and practical questions concerning the design of research and analysis in this area.

Allostatic load score and lifestyle factors in the SWAN cohort: A longitudinal analysis

Objectives

Allostatic load (AL) has been used to assess chronic stress. Previous studies have assessed associations between lifestyle factors and the AL. However, those studies have yet to evaluate associations longitudinally. Thus, the effect of lifestyle factors on the AL changes over time remains to be determined.

Study design

A longitudinal analysis was designed.

Methods

Our study included 1976 women identified from the Study of Women's Health Across the Nation (SWAN) who had completed at least seven waves of measurements since baseline. The Poisson mixed effects model was used to model AL and to assess how lifestyle factors affected AL over time.

Results

At baseline, the mean AL score was 2.44 (range 0-11). On average, the AL score increased by 3 % (ORs = 1.03, 95 % CI [1.01, 1.05]) per wave over time. For lifestyle factors, women who smoked cigarettes over time had higher AL than those who never smoked. On the other hand, women who ever drank alcohol at baseline, had leisure physical activity over time, and had at least average sleep quality at baseline, and had lower AL than their counterparts. We also identified a statistically significant interaction between alcohol drinking and time (P < 0.01). Furthermore, we generated a healthy score using the four lifestyle factors above to assess the potential accumulative effect of lifestyle factors on AL. We found that the AL increased by 16 % for each additional unhealthy lifestyle factor (ORs = 1.16, 95%CI: 1.12, 1.2).

Conclusions

This study demonstrates that lifestyle factors can influence the increase of AL over time.

Mental fatigue and return to well-being in athletes: roles of cognitive reappraisal, gender, and alcohol consumption

This study aimed to investigate the impact of mental fatigue awareness on psychological recovery processes in athletes. It also examines the mediating role of cognitive reappraisal and the moderating effects of gender and alcohol use. A sample of 639 active athletes from diverse regions of Turkey participated in the online study. Data were collected through the Sport Psychological Recovery Scale, the Emotion Regulation Scale for Athletes, and the Mental Fatigue Awareness Scale in Athletes. The findings indicate that mental fatigue awareness has a direct, negative effect on recovery (β = -0.2526, p < 0.001). Also, cognitive reappraisal partially mediates this relationship (β = -0.236, p < 0.001). Gender was identified as a significant moderator, with women exhibiting a stronger negative impact of mental fatigue awareness on their recovery processes compared to men. However, the moderating effect of alcohol consumption was not statistically significant. The study contributes to the understanding of the interplay between mental fatigue awareness and recovery in athletes, highlighting the influence of cognitive and emotional regulation and the importance of gender as a moderating variable. Future research should employ longitudinal designs and larger samples to explore these relationships in greater depth.

Examining Trajectories of Momentary Affect Surrounding NSSI and Alcohol Use: A Network Analysis and Bayesian Approach

OBJECTIVES

This study aimed to identify specific affective antecedents of non-suicidal self-injury (NSSI) and alcohol use, and to examine affective trajectories before and after these behaviors.

METHOD

Fifty-six undergraduates (71% female, 25% non-White, 20.2 ± 1.3 years old) meeting criteria for probable alcohol or substance use disorder participated in 28-days of ecological momentary assessment, completing four daily surveys assessing affect, self-punishment cognitions, and engagement in NSSI and alcohol use. Contemporaneous and time-lagged graphical vector autoregressive (GVAR) models were used to examine affect dynamics surrounding NSSI and alcohol use. Zero-inflated Bayesian binomial regression was used to investigate the relationship between momentary affect and likelihood of engaging in either NSSI or alcohol at the next prompt. Multilevel modeling was used to examine trajectories of affective states pre- and post-engagement in NSSI and alcohol use.

RESULTS

GVAR models revealed significant relationships between jitteriness and being afraid with next timepoint NSSI, and excitement with next timepoint alcohol use. Bayesian regression with horseshoe priors identified self-punishment and loneliness as predictors of NSSI. Moreover, Bayesian regression revealed that excitement predicted alcohol use among those without alcohol use disorder (AUD), while belongingness predicted alcohol use among those with AUD. Multilevel models revealed self-punishment and loneliness followed a negative quadratic trajectory around NSSI events. Excitement and belongingness did not relate to slopes of time.

CONCLUSIONS

The findings suggest NSSI is used to reduce negative emotional states, whereas alcohol consumption initially enhances positive emotional states in individuals without an AUD and may be used to increase belongingness in those with an AUD.

Alcohol, affective atmospheres and structures of feeling in women at midlife

INTRODUCTION

Women at midlife have increased rates of harmful drinking in many high-income countries. This cohort grew up within permissive alcohol environments that encouraged women's consumption, linking it to success, femininity, and empowerment. This research drew on notions of 'structures of feeling' and 'affective atmospheres' to explore how women at midlife describe and make sense of alcohol and drinking within their lives.

METHODS

Eight friendship discussion groups and 17 individual interviews were conducted with 50 women (aged 35-59 years) in Aotearoa/New Zealand about alcohol and drinking. Transcripts were analysed using an affective-discursive approach.

FINDINGS

Shaped by idealised femininities and alcohol's chemical affordances, particular affective atmospheres and feelings arose in women before, during, and after drinking, providing insights into women's experiences and sense-making around alcohol. Three areas of life were highly affectively charged in discussions, namely drinking that: 1) enabled bonding with partner, 2) facilitated time out from busy lives, and 3) was part of coping with life's difficulties.

DISCUSSION AND CONCLUSIONS

Women at midlife experienced pressures to be economically and socially successful, to maintain slim bodies, and to have 'appropriate' feelings such as selflessness and gratitude. For women in this study, drinking alcohol was a way to achieve, and to cope with, expectations around idealised femininities and socially endorsed ways of living, being, and feeling. Repeated and routine affective experiences reinforced the role of alcohol in women's lives. Findings suggest the need for gender-transformative policies that address the structural environments of women's lives.

Smoking, alcohol consumption, and risk of recurrent falls in community-dwelling Japanese people aged 40-74 years: The Murakami cohort study

AIM

Evidence is lacking regarding associations between smoking/drinking and falls. This study aimed to determine longitudinal associations between smoking, alcohol consumption, and fall risk in middle-aged and older people.

METHODS

Participants of this cohort study were 7542 community-dwelling Japanese people aged 40-74 years. The baseline self-administered questionnaire survey was conducted in 2011-2013, and the second survey was conducted 5 years later. Predictors were smoking level and alcohol consumption. The outcome was the occurrence of recurrent falls. Information on self-reported falls in the previous year was obtained. Covariates were demographics, lifestyle factors, body mass index, general health status, and disease history.

RESULTS

The mean age of participants was 60.3 years. Higher smoking levels were associated with a higher recurrent fall risk (adjusted P for trend = 0.0386), with the ≥20 cigarettes/day group having a higher risk (adjusted odds ratio [OR] = 1.93, 95% confidence interval [CI]: 1.20-3.10) than lifetime non-smokers. The association between smoking and recurrent fall risk tended to be stronger in drinkers than in non-drinkers (adjusted OR = 2.75, 95% CI: 1.57-4.81), suggesting a potential interaction (P for interaction = 0.1035). Although there were no dose-dependent associations between alcohol consumption and recurrent fall risk overall, moderate alcohol consumption (150-299 g ethanol/week) was associated with a lower risk (adjusted OR = 0.57, 95% CI: 0.33-0.98) compared with no consumption in men.

CONCLUSIONS

Smoking, but not alcohol consumption, is dose-dependently associated with high fall risk. However, moderate alcohol consumption may be associated with a decreased fall risk. Moreover, there may be a potential interaction between smoking and alcohol consumption on fall risk. Geriatr Gerontol Int 2025; 25: 67-74.

Investigating a visceral measure of perceived physical attractiveness

Perceptions of physical attractiveness are typically assessed using numeric rating scales. As with other visceral experiences, perceptions of physical attractiveness may benefit from multimodal measurement. Recently, we developed and validated a squeeze (dynamometer) method to evaluate two "visceral" states (hunger and cigarette craving). Here, we extend this approach to perceptions of physical attractiveness. Participants (n = 33) viewed a series of static facial images. Perceptions of physical attractiveness were assessed using the dynamometer, followed by a traditional rating scale ranging from 1 (very unattractive) to 10 (very attractive). Participants also reported desire to (a) interact with each individual they viewed in a future study and (b) become friends with each individual they viewed, using a Likert scale. Dynamometer-measured perceptions of physical attractiveness were significantly associated with traditional perceptions of physical attractiveness ratings and predicted both desire outcomes. Findings offer initial support for a visceral approach to perceptions of physical attractiveness that can complement traditional rating scales.

Dynamics trajectory of patient-reported quality of life and its associated risk factors among hepatocellular carcinoma patients receiving immune checkpoint inhibitors: a prospective cohort study

Objective

We aimed to characterize quality of life (QOL) trajectories among patients with intermediate and advanced hepatocellular carcinoma patients treated with immunotherapy.

Methods

Barcelona Clinic Liver Cancer (BCLC) stage B-C HCC patients receiving immunotherapy at Guangxi Medical University Cancer Hospital were included. Trajectories of QOL, assessed using the Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep) questionnaire, were identified through iterative estimations of group-based trajectory models. Associations with trajectory group membership were analyzed using multivariable multinomial logistic regression.

Results

Three trajectory groups were identified (n=156): excellent (35.3%), poor (43.6%), and deteriorating (21.1%) QOL. The deteriorating trajectory group reported a mean QOL score of 124.79 (95% CI, 116.58-133.00), but then declined significantly at month-2 (estimated QOL score 98.67 [95% CI, 84.33-113.00]), and the lowest mean score is reached at month-6 (estimated QOL score 16.58 [95% CI, 0-46.07]). Factors associated with membership to the deteriorating group included no drinking (odds ratio [OR] vs yes [95% CI], 3.70 [1.28-11.11]), no received radiotherapy (OR vs yes [95% CI], 8.33 [1.41-50.00]), diabetes (OR vs no [95% CI], 6.83 [1.57-29.73]), and extrahepatic metastasis (OR vs no [95% CI], 3.08 [1.07-8.87]). Factors associated with membership to the poor group also included body mass index ≤24.0 kg/m2 (OR vs no [95% CI], 4.49 [1.65-12.22]).

Conclusions

This latent-class analysis identified a high-risk cluster of patients with severe, persistent post-immunotherapy QOL deterioration. Screening relevant patient-level characteristics may inform tailored interventions to mitigate the detrimental impact of immunotherapy and preserve QOL.

Reciprocal relations between acute interpersonal negative life events and acute alcohol use: An examination of the 24 h preceding suicide attempts among hospitalized patients

OBJECTIVE

To examine the within-person relations between acute alcohol use and interpersonal negative life events (INLEs) in the 24 h preceding suicide attempts.

METHOD

Participants were 151 adult patients (67.55 % female; M age = 36.00) who were hospitalized within 24 h of a suicide attempt. Participants completed the Timeline Follow-back for Suicide Attempts interview to gather information about hourly events for the 24 h preceding their suicide attempt. Hierarchical logistic models were estimated to examine the influence of acute INLEs on next-hour alcohol use and acute alcohol use on next-hour INLEs. Biological sex and chronic alcohol use (past year) were evaluated as potential moderators.

RESULTS

Overall, acute alcohol use was associated with increased odds of next-hour INLEs and acute INLEs were associated with increased odds of next-hour alcohol use. Moderator analyses indicated that the influence of alcohol use on INLEs increased as participants' level of chronic alcohol use decreased, and relations did not vary by biological sex.

CONCLUSIONS

There is a bidirectional relation between INLEs and alcohol use in the hours preceding suicide attempts. Understanding that these within-person interrelations may differ in strength depending on one's level of chronic alcohol use has practical utility for providers tasked with clinical decision making.

Work context and drinking behavior in the French public service: a qualitative study

Introduction

Alcohol use disorders (AUD) are a major public health problem. Among the working population, alcohol is the most frequently used psychoactive substance, as well as the most inappropriately used. Alcohol consumption reduces the worker's psychophysical integrity, leads to an increase in inappropriate behavior, accidents and injuries, and affects the safety and health of other workers. Thus, the workplace must play an essential role in prevention. Particularly in France, in the civil service, a specific professional sector made up of many professionals exposed to stress, the prevention of AUD must play an essential role. The objective of this study was to describe the framework of alcohol consumption in the French public service in order to understand the sources of alcohol consumption behaviors and to identify the prevention measures to be implemented, in order to reduce the risk of transition to an alcohol use disorder.

Methods

This descriptive qualitative study was based on focus groups. Sampling was purposive and data saturation was verified. Coding was "in vivo," descriptive and pattern-oriented. Analysis was inductive thematic, and the COREQ guidelines were followed.

Results

Firstly, the presence of alcohol in the workplace has been characterized by a before-and-after a prohibition law, and by the revelation of mechanisms for avoiding the ban. Then, the three main determinants for alcohol use disorders were: society, work and personal factors. Lastly, the prevention initiatives identified must be based on both collective and individual approaches. They must be encouraged by the hierarchy, include screening, accompaniment to care, and take into account both work in the workplace and work at home. The fight against work-related alcohol use disorders must be part of the corporate culture.

Discussion

Preventing alcohol-related disorders among civil servants will help fight the burden of non-communicable diseases.

Effects of voluntary chronic intermittent access to ethanol on the behavioral performance in adult C57BL/6 J mice

BACKGROUND

Chronic alcohol drinking increases the risk of alcohol use disorders, causing various neurological disorders. However, the impact of different ethanol levels on a spectrum of behaviors during chronic drinking remains unclear. In this study, we established an intermittent access to ethanol in a two-bottle choice (IA2BC) procedure to explore the dose-dependent effects of ethanol on the behavioral performance of C57BL/6 J mice.

METHODS

Adult male C57BL/6 J mice were provided voluntary access to different ethanol concentrations (0 %, 5 %, 10 %, and 20 % ethanol) under a 12-week IA2BC paradigm. A battery of behavioral tests was administered to assess alterations in pain threshold, anxiety-like behaviors, locomotor activity, motor coordination, and cognition. Ethanol consumption and preference were monitored during each session. Moreover, the liver, heart, and lung tissues were examined using pathological microscopy.

RESULTS

The average (standard deviation) ethanol consumption of mice under the IA2BC paradigm increased dose-dependently to 5.1 (0.2), 8.7 (0.7), and 15.9 (0.8) g/kg/24 h with 5 %, 10 %, and 20 % ethanol, respectively. However, there is no significant difference in ethanol preference among all the ethanol groups. Chronic ethanol drinking caused hyperalgesia, cognitive impairment, and motor incoordination, but caused no changes in body temperature, locomotor activity, or anxiety-like behaviors. Minor histopathological alterations in the liver were detected; however, no major abnormal pathology was observed in the heart or lungs.

CONCLUSION

These findings clarify the link between ethanol dosage and behavioral changes in mice over a 12-week IA2BC paradigm, thereby bridging the knowledge gap regarding the effects of chronic ethanol drinking on neurological disorders.

Limited evidence that alcohol affects emotional face processing via interoceptive pathways, a registered report

BACKGROUND

Our brain uses interoceptive signals from the body to shape how we perceive emotions in others; however, whether interoceptive signals can be manipulated to alter emotional perceptions is unknown. This registered report examined whether alcohol administration triggers physiological changes that alter interoceptive signals and manipulate emotional face processing.

METHODS

Participants (n=36) were administered an alcohol or placebo beverage. Cardiovascular physiology (Heartrate variability, HRD) was recorded before and after administration. Participants completed a behavioral task in which emotional faces were presented in synchrony with different phases of the cardiac cycle (i.e., systole/diastole) to index of how interoceptive signals amplify them.

HYPOTHESES

We hypothesized that alcohol administration would disrupt the cardiac amplification of emotional face processing. We further explored whether this disruption depended on the nature and magnitude of changes in cardiovascular physiology after alcohol administration.

RESULTS

We observed no main effects or interactions between alcohol administration and emotional face processing. We found that HRV at baseline negatively correlated with the cardiac amplification of emotional faces. The extent to which alcohol impacted HRV negatively correlated with the cardiac amplification of angry faces.

CONCLUSIONS

This registered report failed to validate the primary hypotheses but offers some evidence that the effects of alcohol on emotional face processing, if any, could be mediated via changes in basic physiological signals that are integrated via interoceptive mechanisms. Results are interpreted within the context of interoceptive inference and could feed novel perspectives for the interplay between physiological sensitivity and interoception in the development of drug-related behaviors.

Impulsivity, mental health state and emotion regulation modulate alcohol and marijuana use in a sample of Argentinean citizens

Impulsivity and substance-related outcomes share a complex relationship, as various facets of impulsivity exhibit distinct associations with different drug-related outcomes. This study examines the associations between frequency and quantity of alcohol and marijuana use with impulsivity traits, psychological distress, and the utilization of emotion regulation strategies. A survey asked Argentinian citizens (n = 1507, 356 men) about frequency and quantity of alcohol or marijuana use on each day of a typical week, as well as anxiety, stress, and depression symptoms (DASS-21), impulsivity-like traits (UPPS-P), and emotion regulation strategies (ERQ). The 2-month prevalence of alcohol or marijuana use was 80.1%, and 27.2%, respectively. Premeditation was significantly (p < 0.05) and negatively associated with both frequency and quantity of alcohol consumed, whereas negative and positive urgency were positively and significantly (p < 0.05) associated with quantity of alcohol or marijuana use, respectively. Greater depression symptoms predicted greater quantity of alcohol use, whereas lower emotional suppression or lower cognitive reappraisal were significantly (p < 0.05) associated with a greater frequency of alcohol or marijuana use. Sensation seeking was significantly (p < 0.05) and positively associated with frequency of marijuana use. Individuals with higher levels of impulsivity-like traits, higher levels of depression, or lower use of emotional regulation abilities appeared to be at a higher risk of alcohol or marijuana use. In this sample, the use of alcohol (though not marijuana) seems to fit a negative reinforcement pathway. The study suggests that individuals with risk factors for drug misuse could benefit from interventions aimed at enhancing emotion regulation.

Alcohol and Periodontal Disease: A Narrative Review

The scientific literature dealing with alcohol and alcoholic beverages revealed that these drinks possess an adverse impact on periodontal tissues. Additionally, other principal risk factors include tobacco, smoking, poor oral hygiene, etc. It has been observed that among chronic alcoholics, there are further issues, such as mental, social, and physical effects, that promote alcoholism. These people may have weak immunity for defense against pathogenic organisms and bacteria. Thus, chances of gingival bleeding, swollen gums, bad breath, and increased bone loss are there. Different alcoholic beverages in the market cause less salivation; these beverages contain sugars that promote acid production in the oral cavity by pathogens that demineralize the enamel and damage gum and teeth. This chronic alcohol consumption can progress into different types of oral disorders, including cancer, halitosis, and caries, and is also associated with tobacco and smoking. Chronic alcohol consumption can cause alteration of the oral microbiome and increase oral pathogens, which lead to periodontal disease and an environment of inflammation created in the body due to malnutrition, diminished immunity, altered liver condition, brain damage, and gut microbiota alteration. Heavily colored alcoholic beverages produce staining on teeth and, due to less saliva, may cause other toxic effects on the periodontium. Over-dependency on alcohol leads to necrotizing lesions such as necrotizing gingivitis, necrotizing periodontitis, and necrotizing stomatitis. These pathological impairments instigate severe damage to oral structures. Therefore, proper counseling by the attending dental surgeon and related health professionals is urgently required for the patient on the basis that the individual case needs to go away from the regular heavy consumption of alcohol.

Alcohol consumption, smoking, and risk of dementia in community-dwelling Japanese people aged 40-74 years: The Murakami cohort study

OBJECTIVE

Alcohol drinking and tobacco smoking have impacts on lifestyle-related diseases, but their association with dementia remains a debated topic. This study aimed to examine longitudinal associations between alcohol consumption, smoking, and dementia risk in middle-aged and older Japanese people.

METHODS

This study used a cohort design with an 8-year follow-up. Participants were community-dwelling Japanese people (N = 13,802) aged 40-74 years. The baseline survey, including a self-administered questionnaire, was conducted in 2011-2013. Predictors were alcohol consumption and tobacco smoking. The outcome was incident dementia obtained from a long-term care insurance database. Covariates were demographics, lifestyle factors, body mass index, general health status, and history of stroke, diabetes, and depression.

RESULTS

Participant mean age was 59.0 years. The 1-149, 150-299, and 300-449 g ethanol/week groups had significantly lower adjusted hazard ratios (HRs) (0.62, 0.59, and 0.47, respectively) compared with the reference group, with no significant linear association. HRs increased toward 1 when past-drinkers and those with poor health status and a disease history were excluded (0.80, 0.66, and 0.82, respectively). Higher smoking levels were dose-dependently associated with a higher HR (adjusted P for trend = 0.0105), with the ≥20 cigarettes/day group having a significantly higher adjusted HR (1.80). Heavy drinkers (≥449 g ethanol/week) with smoking habits, but not those without smoking habits, had higher dementia risk (P for interaction = 0.0046).

CONCLUSION

Light-to-moderate alcohol consumption is associated with decreased dementia risk, and smoking is dose-dependently associated with increased dementia risk, with an interaction between high alcohol consumption and smoking on dementia risk.

Trends in deaths following drug use in England before, during, and after the COVID-19 lockdowns

Aim

This research aimed to describe how the characteristics of deaths following drug use changed during the COVID-19 pandemic in England, and how this can inform future strategy to support the health and social care of people who use drugs in future emergency scenarios.

Method

All deaths reported to the National Programme on Substance Abuse Deaths which occurred between January 2018 and December 2021 inclusive were extracted for analysis. Exponential smoothing models were constructed to determine any differences between forecasted vs. actual trends.

Key results

Following the first lockdown period in England there were significant increases in the proportion of people who died at home beyond the 95% confidence bounds of the exponential smoothing model and concurrent decreases in the proportion of people who died in hospital. Whilst the overall proportion of deaths attributable to opioids did not significantly deviate from the forecasted trend, there were significant increases in methadone-related deaths and decreases in heroin/morphine-related death beyond the 95% confidence bounds. The proportion of deaths concluded as suicide increased, as did those implicating antidepressant use. There were no changes in the proportion of deaths following use of other drug classes, alcohol use in combination with psychoactive drugs, or on decedent demographics (gender, age, and drug user status). A small number of deaths due to drug use had COVID-19 infection itself listed as a cause of death (n = 23).

Conclusion

For people who use drugs, the impact of the restrictions due to the COVID-19 pandemic was greater than that of infection from the virus itself. The health and social care strategy for these people needs to be pre-emptively adapted to mitigate against the specific risk factors for fatal drug overdose associated with future emergency scenarios.

Beer Goggles or Liquid Courage? Alcohol, Attractiveness Perceptions, and Partner Selection Among Men

OBJECTIVE

Perception of physical attractiveness (PPA) is a fundamental aspect of human relationships and may help explain alcohol's rewarding and harmful effects. Yet PPA is rarely studied in relation to alcohol, and existing approaches often rely on simple attractiveness ratings. The present study added an element of realism to the attractiveness assessment by asking participants to select four images of people they were led to believe might be paired with them in a subsequent study.

METHOD

Dyads of platonic, same-sex male friends (n = 36; ages 21-27; predominantly White, n = 20) attended two laboratory sessions wherein they consumed alcohol and a no-alcohol control beverage (counterbalanced). Following beverage onset, participants rated PPA of targets using a Likert scale. They also selected four individuals from the PPA rating set to potentially interact with in a future study.

RESULTS

Alcohol did not affect traditional PPA ratings but did significantly enhance the likelihood that participants would choose to interact with the most attractive targets, χ2(1, N = 36) = 10.70, p < .01.

CONCLUSIONS

Although alcohol did not affect traditional PPA ratings, alcohol did increase the likelihood of choosing to interact with more attractive others. Future alcohol-PPA studies should include more realistic contexts and provide assessment of actual approach behaviors toward attractive targets, to further clarify the role of PPA in alcohol's hazardous and socially rewarding effects.

Self-management with alcohol over lifespan: psychological mechanisms, neurobiological underpinnings, and risk assessment

Self-management includes all behavioural measures and cognitive activities aimed at coping with challenges arising throughout the lifespan. While virtually all of these challenges can be met without pharmacological means, alcohol consumption has long been instrumentalized as a supporting tool to help coping with problems arising selectively at adolescence, adulthood, and ageing. Here, we present, to our knowledge, the first systematic review of alcohol instrumentalization throughout lifespan. We searched MEDLINE, Google Scholar, PsycINFO and CINAHL (from Jan, 1990, to Dec, 2022) and analysed consumption patterns, goals and potential neurobiological mechanisms. Evidence shows a regular non-addictive use of alcohol to self-manage developmental issues during adolescence, adulthood, and ageing. Alcohol is selectively used to overcome problems arising from dysfunctional personality traits, which manifest in adolescence. A large range of psychiatric disorders gives rise to alcohol use for the self-management of distinct symptoms starting mainly in adulthood. We identify those neuropharmacological effects of alcohol that selectively serve self-management under specific conditions. Finally, we discuss the adverse effects and associated risks that arise from the use of alcohol for self-management. Even well-controlled alcohol use adversely impacts health. Based on these findings, we suggest the implementation of an entirely new view. Health policy action may actively embrace both sides of the phenomenon through a personalized informed use that allows for harm-controlled self-management with alcohol.

Predictors of Hangover Frequency and Severity: The Impact of Alcohol Consumption, Mental Resilience, Personality, Lifestyle, Coping and Mood

Mental resilience is the ability to bounce back from daily life stressors such as divorce or losing a job. Extensive research has demonstrated a negative relationship between mental resilience and alcohol consumption. That is, both the quantity and frequency of alcohol consumption are greater in individuals with lower levels of mental resilience. There has, however, been little scientific attention paid to the relationship between mental resilience and alcohol hangover severity. The objective of this study was to evaluate psychological factors that may impact the frequency and severity of alcohol hangovers, including alcohol intake itself, mental resilience, personality, baseline mood, lifestyle, and coping mechanisms. An online survey was conducted among Dutch adults (N = 153) who had a hangover after their heaviest drinking occasion in the period before the start of the COVID-19 pandemic (15 January to 14 March 2020). Questions were asked about their alcohol consumption and hangover severity on their heaviest drinking occasion. Mental resilience was assessed with the Brief Mental Resilience scale, personality with the Eysenck Personality Questionnaire-Revised Short Scale (EPQ-RSS), mood via single item assessments, and lifestyle and coping with the modified Fantastic Lifestyle Checklist. The partial correlation, corrected for estimated peak blood alcohol concentration (BAC), between mental resilience and hangover severity was not significant (r = 0.010, p = 0.848). Furthermore, no significant correlations were found between hangover severity or frequency and personality and baseline mood. For lifestyle and coping factors, a negative correlation was found between the use of tobacco and toxins (i.e., drugs, medicines, caffeine) and the frequency of experiencing hangovers. Regression analysis revealed that hangover severity after the heaviest drinking occasion (31.2%) was the best predictor of hangover frequency, and that subjective intoxication on the heaviest drinking occasion (38.4%) was the best predictor of next-day hangover severity. Mood, mental resilience, and personality were not relevant predictors of hangover frequency and severity. In conclusion, mental resilience, personality, and baseline mood do not predict hangover frequency and severity.

Women, alcohol consumption and health promotion: the value of a critical realist approach

Research on women's drinking occurs in largely disparate disciplines-including public health, health promotion, psychology, sociology, and cultural studies-and draws on differing philosophical understandings and theoretical frameworks. Tensions between the aims and paradigmatic underpinnings of this research (across and within disciplines) have meant that knowledge and insight can be frequently disciplinary-specific and somewhat siloed. However, in line with the social and economic determinants of the health model, alcohol research needs approaches that can explore how multiple gender-related factors-biological, psycho-social, material, and socio-cultural-combine to produce certain drinking behaviours, pleasures and potential harms. We argue that critical realism as a philosophical underpinning to research can accommodate this broader conceptualization, enabling researchers to draw on multiple perspectives to better understand women's drinking. We illustrate the benefit of this approach by presenting a critical realist theoretical framework for understanding women's drinking that outlines interrelationships between the psychoactive properties of alcohol, the role of embodied individual characteristics and the material, institutional and socio-cultural contexts in which women live. This approach can underpin and foster inter-disciplinary research collaboration to inform more nuanced health promotion practices and policies to reduce alcohol-related harm in a wide range of women across societies.

Elixir of love or venom of violence: When does a drinking event result in couple intimacy or couple conflict?

The short-term consequences of drinking events may be positive or negative. Most studies have considered only one outcome, but people may experience different alcohol outcomes on different occasions, depending on the circumstances. The present study sought to identify predictors of drinking events that resulted in couple intimacy, conflict, or neither outcome using existing data from a 30-day ecological momentary assessment (EMA) study. Participants were a community sample of partnered, moderately drinking adults with a recent history of verbal or physical partner aggression (N = 249 couples). They provided reports of drinking events, intimacy and conflict events, and ratings of relationship harmony and discord in three randomly signaled reports each day. Mixed-effects multinomial analyses were used to compare predictors of drinking events that, within three hours, resulted in intimacy, conflict, or neither outcome. Consistent with previous research, characteristics of the drinker (individual tendencies to experience intimacy or conflict) and characteristics of the drinking event (alcohol quantity, drinking companions) both predicted drinking outcomes. Moreover, the pre-drinking relationship context predicted post-drinking relationship outcomes, consistent with the idea that alcohol focuses attention on salient contextual cues. Specifically, greater pre-drinking relationship harmony predicted greater likelihood of experiencing intimacy after drinking, whereas greater pre-drinking relationship discord predicted greater likelihood of experiencing conflict after drinking. In summary, characteristics of the drinker, the drinking event, and the pre-drinking relationship context contribute to the likelihood that a given drinking event will have short-term positive or negative relationship outcomes.

The daily association between affect and alcohol use: A meta-analysis of individual participant data

Influential psychological theories hypothesize that people consume alcohol in response to the experience of both negative and positive emotions. Despite two decades of daily diary and ecological momentary assessment research, it remains unclear whether people consume more alcohol on days they experience higher negative and positive affect in everyday life. In this preregistered meta-analysis, we synthesized the evidence for these daily associations between affect and alcohol use. We included individual participant data from 69 studies (N = 12,394), which used daily and momentary surveys to assess affect and the number of alcoholic drinks consumed. Results indicate that people are not more likely to drink on days they experience high negative affect, but are more likely to drink and drink heavily on days high in positive affect. People self-reporting a motivational tendency to drink-to-cope and drink-to-enhance consumed more alcohol, but not on days they experienced higher negative and positive affect. Results were robust across different operationalizations of affect, study designs, study populations, and individual characteristics. These findings challenge the long-held belief that people drink more alcohol following increases in negative affect. Integrating these findings under different theoretical models and limitations of this field of research, we collectively propose an agenda for future research to explore open questions surrounding affect and alcohol use.

The Influence of Alcohol on Rumination and Metacognitions in Major Depressive Disorder

Background and Objectives

Comorbidity between major depressive disorder (MDD) and alcohol use disorder (AUD) is highly prevalent but reasons for this association are unclear. Rumination may activate metacognitive beliefs that contribute to the development and maintenance of rumination and depression. Negative metacognitions can further lead to other dysfunctional coping strategies (i.e., consumption of alcohol). We examined whether alcohol reduces (state) metacognitions, rumination and other disorder-specific processes in a group of individuals suffering from MDD.

Method

In an experiment with three randomized conditions we investigated whether the consumption of alcohol, placebo or no alcohol (orange juice) affects (meta-)cognitions, depressive symptoms and / or psychophysiological variables while participants ruminate.

Results

Voluntary rumination increased self-reported sadness, tension and rumination, tensed facial muscles and increased heart rate, but did not affect (state) metacognitions and heart rate variability. The consumption of alcohol did not influence rumination, metacognitions, depressive or psychophysiological measures.

Limitations

We recruited a depressed population but excluded pathological alcohol use due to ethical considerations.

Conclusions

We found no evidence that alcohol consumption affects rumination, metacognitions and other disorder-specific processes in MDD. However, rumination had a negative effect on various depression-specific processes, although it did not activate (negative state) metacognitions.

A social contextual review of the effects of alcohol on emotion

Drinking and drinking problems are complex phenomena. Understanding the etiology of alcohol use disorder requires consideration of biological, psychological, and social processes. It is our view that the last of these dimensions is just beginning to receive adequate scrutiny. In this selective review, we discuss the concept of a biopsychosocial analysis of the effects of alcohol. After briefly addressing biological and psychological research on alcohol's emotional effects, we bid to make a case for the vital role that social processes play in understanding why people drink. The bulk of the paper describes research illustrating the contributions that a social psychological perspective can make to advance understanding of the rewarding effects of alcohol. Overall, studies incorporating social contexts have revealed reliable evidence that alcohol enhances emotional experience in many social environments and have identified socio-contextual variables that moderate responses to alcohol. Further, these studies have broadened the scope of constructs thought to be socially rewarding, including social bonding, relationship functioning, and humor enjoyment. Our analysis concludes by identifying research areas we believe would profit from additional research.

Unraveling the epigenomic and transcriptomic interplay during alcohol-induced anxiolysis

Positive effects of alcohol drinking such as anxiolysis and euphoria appear to be a crucial factor in the initiation and maintenance of alcohol use disorder (AUD). However, the mechanisms that lead from chromatin reorganization to transcriptomic changes after acute ethanol exposure remain unknown. Here, we used Assay for Transposase-Accessible Chromatin followed by high throughput sequencing (ATAC-seq) and RNA-seq to investigate epigenomic and transcriptomic changes that underlie anxiolytic effects of acute ethanol using an animal model. Analysis of ATAC-seq data revealed an overall open or permissive chromatin state that was associated with transcriptomic changes in the amygdala after acute ethanol exposure. We identified a candidate gene, Hif3a (Hypoxia-inducible factor 3, alpha subunit), that had 'open' chromatin regions (ATAC-seq peaks), associated with significantly increased active epigenetic histone acetylation marks and decreased DNA methylation at these regions. The mRNA levels of Hif3a were increased by acute ethanol exposure, but decreased in the amygdala during withdrawal after chronic ethanol exposure. Knockdown of Hif3a expression in the central nucleus of amygdala attenuated acute ethanol-induced increases in Hif3a mRNA levels and blocked anxiolysis in rats. These data indicate that chromatin accessibility and transcriptomic signatures in the amygdala after acute ethanol exposure underlie anxiolysis and possibly prime the chromatin for the development of AUD.

Alcohol's effects during uncertain and uncontrollable stressors in the laboratory

Alcohol's effects on reactivity to stressors depends on the nature of the stressor and the reactivity being assessed. Research identifying characteristics of stressors that modulate reactivity and clarifies the neurobehavioral, cognitive, and affective components of this reactivity may help prevent, reduce or treat the negative impacts of acute and chronic alcohol use with implications for other psychopathology involving maladaptive reactivity to stressors. We used a novel, multi-measure, cued electric shock stressor paradigm in a greater university community sample of adult recreational drinkers to test how alcohol (N=64), compared to No-alcohol (N=64), effects reactivity to stressors that vary in both their perceived certainty and controllability. Preregistered analyses suggested alcohol significantly dampened subjective anxiety (self-report) and defensive reactivity (startle potentiation) more during uncertain than during certain stressors regardless of controllability, suggesting that stressor uncertainty -but not uncontrollability- may be sufficient to enhance alcohol's stress reactivity dampening and thus negative reinforcement potential.

[Depression, anxiety and stress in college students before and during the first three months of COVID-19 lockdown]

Introduction: Different psychological symptoms of distress as well as drinking motives have been associated with alcohol use in college students. The COVID-19 lockdown [aislamiento social, preventivo y obligatorio (ASPO)] reduced movement to a minimum, impacting college students' mental health and generating changes in several behaviours, including alcohol use.Objectives: To examine the association between symptoms of anxiety, depression and stress, drinking motives and alcohol use in two groups of Argentinian college students, before and during the first three months of lockdown. In addition, it was examined whether drinking motives mediate the relationship between psychological distress and alcohol use.Methods: Two samples of college students, one before the lockdown (n=125; mean age, 23.87 ± 3.27 years; 73.6% women) and another during the lockdown (n=174; 24.32 ± 3.64 years; 78.2% women) completed an online survey.Results: Alcohol use, as well as social and enhancement motives, decreased in college students during lockdown. The associations between psychological distress and drinking motives with alcohol use were more consistent in the group during lockdown compared with the group after lockdown. At a multivariate level, coping motives explained an increased frequency of alcohol consumption in college students during lockdown.Conclusions: It is necessary to pay special attention to the mental health of college students who have experienced changes in their routines as a result of the restrictions implemented during the pandemic.

Different Ways to Drown Out the Pain: A Meta-Analysis of the Association Between Nonsuicidal Self-Injury and Alcohol Use

OBJECTIVE

There is a significant overlap in the motivations for nonsuicidal self-injury (NSSI) and alcohol use. Moreover, several theories would predict that more frequent alcohol use is likely associated with more NSSI engagement. Still, the size and direction of this association has not been well documented in the literature.

METHOD

To address this gap, the goal of this article was to conduct a meta-analysis of the relation between alcohol use and NSSI.

RESULTS

Across 57 samples and 141,669 participants, we found that there was a significant positive association between NSSI and alcohol use, odds ratio = 1.78, 95% confidence interval [1.53, 2.07], k = 64, m = 52. Moderator analyses found that this effect was stronger for younger samples and samples with more severe alcohol use problems.

CONCLUSIONS

These results help establish a link between NSSI and alcohol use. Implications and future directions for NSSI research and intervention are discussed.HighlightsThere are several reasons to think that NSSI and alcohol use are linked.No reviews or meta-analyses have been conducted.We found a significant and small effect linking greater NSSI with greater alcohol use.

Longitudinal Associations of Former and Current Alcohol Consumption with Psychosocial Outcomes among Colorectal Cancer Survivors 1-15 Years after Diagnosis

We aimed to explore positive and negative associations of consuming alcohol with psychosocial outcomes among colorectal cancer (CRC) survivors. We used data of an observational prospective cohort study, consisting of 2625 Dutch CRC survivors enrolled 1-11 years post-diagnosis that were followed-up in 4 yearly surveys. Generalized estimated equation models were used to examine longitudinal associations between alcohol consumption and anxiety, depression, and health-related quality of life (HRQoL), while correcting for sociodemographic, lifestyle and clinical characteristics. Compared to lifetime abstainers, former alcohol consumption was associated with more depressive symptoms, and worse global quality of life and social functioning, while current drinking was associated with less anxiety, depression and better HRQoL. More drinks per week was associated with less nausea/vomiting. Compared to abstainers, moderate (≤7 drinks/week) and heavy alcohol consumption (>7 drinks/week) were associated with less anxiety and depression and better HRQoL, mostly attributable to wine consumption. Whereas current alcohol consumption was longitudinally associated with less anxiety and depression and better HRQoL, former drinking was associated with worse psychosocial outcomes, although based on a small sample size. It is important to consider that besides the potential negative effects of alcohol on patients' health, alcohol consumption may be positively related with psychosocial outcomes.Supplemental data for this article is available online at https://doi.org/10.1080/01635581.2022.2044063.

Emotion dysregulation and hazardous drinking in relation to suicidal ideation among Spanish-speaking Latinx daily-smokers

OBJECTIVE

Suicidal ideation has increased among Latinx individuals in the last decade. Smoking increases the likelihood of suicidal ideation but work on Latinx smokers is minimal. Hazardous drinking and emotion dysregulation could be factors related to suicidal ideation among Latinx smokers, as has been evident in non-Latinx White samples. The current study sought to examine the main and interactive effects of emotion dysregulation and hazardous drinking in relation to suicidal ideation among Latinx daily-smokers.

METHODS

Participants were 371 Spanish-speaking daily-smokers (58.8% female; M_age = 33.3; SD_age = 9.8) recruited from the United States through Qualtrics. We used structural equation modeling (SEM) to test an interactive model of emotion dysregulation and hazardous alcohol consumption in relation to suicidal ideation; we also tested the effect of emotion dysregulation on suicidal ideation as a function of hazardous drinking status.

RESULTS

Results indicated that latent emotional dysregulation was associated with greater suicidal ideation (p < 0.001); however, hazardous drinking was not related to suicidal ideation (p = 0.186). The interactive term of emotional dysregulation and hazardous drinking was significantly related to suicidal ideation (p = 0.017). Specifically, greater emotion dysregulation was significantly related to suicidal ideation among Latinx smokers who engaged in hazardous drinking (p < 0.001) but not those who did not engage in hazardous drinking (p = 0.123).

CONCLUSIONS

The current findings suggest that smoking combined with hazardous drinking may be related to increased suicidal ideation among Latinx smokers. Findings are discussed in relation to the potential role of intervention strategies that focus on emotion dysregulation and hazardous drinking among Latinx current daily smokers to mitigate suicidal risk among this established health disparities population.

Drinking and smoking polygenic risk is associated with childhood and early-adulthood psychiatric and behavioral traits independently of substance use and psychiatric genetic risk

Alcohol drinking and tobacco smoking are hazardous behaviors associated with a wide range of adverse health outcomes. In this study, we explored the association of polygenic risk scores (PRS) related to drinks per week, age of smoking initiation, smoking initiation, cigarettes per day, and smoking cessation with 433 psychiatric and behavioral traits in 4498 children and young adults (aged 8-21) of European ancestry from the Philadelphia neurodevelopmental cohort. After applying a false discovery rate multiple testing correction accounting for the number of PRS and traits tested, we identified 36 associations related to psychotic symptoms, emotion and age recognition social competencies, verbal reasoning, anxiety-related traits, parents' education, and substance use. These associations were independent of the genetic correlations among the alcohol-drinking and tobacco-smoking traits and those with cognitive performance, educational attainment, risk-taking behaviors, and psychopathology. The removal of participants endorsing substance use did not affect the associations of each PRS with psychiatric and behavioral traits identified as significant in the discovery analyses. Gene-ontology enrichment analyses identified several neurobiological processes underlying mechanisms of the PRS associations we report. In conclusion, we provide novel insights into the genetic overlap of smoking and drinking behaviors in children and young adults, highlighting their independence from psychopathology and substance use.

Maternal personality and alcohol use during pregnancy in Japan: The Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study

BACKGROUND

Studies on associations between maternal personality and alcohol use have examined only one time point during pregnancy in Western countries. We aimed to examine the association between maternal personality and alcohol use in early and middle pregnancy in Japan.

METHODS

We analyzed data from 17,144 pregnant women in Japan who participated in the Tohoku Medical Megabank Project Birth and Three-Generation Cohort Study from 2013 to 2017. Personality was assessed using the short-form Eysenck Personality Questionnaire-Revised. Women were dichotomized as current drinkers or non-drinkers in both early and middle pregnancy. Odds ratios (ORs) and 95% confidence intervals (CIs) for alcohol use in early and middle pregnancy and continued alcohol use between early and middle pregnancy were calculated for 1 standard deviation increase in each personality scale, adjusted for age, as well as education, work status, fertility treatment, and parity.

RESULTS

Higher extraversion scores were associated with alcohol use in early (OR, 1.16; 95% CI, 1.12-1.20) and middle pregnancy (OR, 1.17; 95% CI, 1.10-1.25). Higher psychoticism scores were associated with continued alcohol use into middle pregnancy (OR, 1.07; 95% CI, 1.01-1.14) and alcohol use in middle pregnancy (OR, 1.07; 95% CI, 1.02-1.13). Neuroticism was not associated with alcohol use in early or middle pregnancy. Lower lie was associated with alcohol use in early (OR, 0.95; 95% CI, 0.91-0.98), but not in middle pregnancy.

CONCLUSIONS

Different personality scales are associated with alcohol use at different points during pregnancy.

Effects of Acute Drug Administration on Emotion: A Review of Pharmacological MRI Studies

Purpose of review

Many drug users claim to use drugs to cope with negative emotions, which may, in turn, result in persistent emotional blunting or anhedonia even when they are not using drugs. The purpose of this review is to describe the ways acute administration of psychoactive drugs impacts brain regions during emotion-related tasks, as a first step in understanding how drugs influence emotion processing in the brain.

Recent findings

Drugs have varying effects on neural responses to emotional stimuli. In general, alcohol, analgesics, and psychedelics reduce neural reactivity to negative emotional stimuli in the amygdala and other brain regions. Other drugs produce mixed effects: Stimulants such as caffeine and modafinil increase brain activation while viewing emotional stimuli, whereas MDMA decreases activation during presentation of negative images. The effects of cannabinoids (cannabidiol and THC) are mixed. There are also inconsistent findings on the associations between neural responses to emotional stimuli and subjective drug effects.

Summary

Consistent with the notion that individuals might use drugs non-medically to diminish the experience of negative emotions, several drugs of abuse decrease neural responses to negative stimuli in limbic brain regions. These neural actions may underlie the reported 'emotional blunting' of drugs, which may contribute to drug-seeking behavior. Future work is needed to examine these limbic responses in relation to self-reports of changes in affect, both during acute administration and after extended drug use.

Associations between alcohol consumption and anxiety, depression, and health-related quality of life in colorectal cancer survivors

Purpose

Alcohol consumption is a major risk factor for colorectal cancer (CRC). It is currently poorly understood, however, how alcohol and different alcoholic beverage types are related to psychosocial outcomes in CRC survivors.

Methods

We used data of N = 910 CRC survivors from the pooled EnCoRe and PROCORE cohorts and harmonized them into five time points: at diagnosis and 3, 6, 12, and 24 months post-diagnosis. Generalized estimated equation models were used to examine longitudinal associations of alcohol consumption, including consumption of beer, wine, and liquor, with anxiety, depression, and health-related quality of life (HRQoL), while correcting for sociodemographic, lifestyle, and clinical factors.

Results

Survivors were on average 67 years and 37% was female. In the first 2 years post-diagnosis, survivors who consumed more alcoholic drinks/week reported lower anxiety and depressive symptoms and better HRQoL on all domains and symptom scales. This was the case for moderate and heavy amounts of alcohol and mostly for consuming beer and wine, but not for liquor. Associations were more often significant for men and for younger persons (< 67 years at baseline).

Conclusions

Generally, alcohol consumption was observed to be longitudinally related to less anxiety and depression and better HRQoL in CRC survivors.

Implications for Cancer Survivors

Although alcohol consumption is generally unfavorable due to increased risk of carcinogenesis and worse prognosis after CRC, it seems to be associated with better psychosocial outcomes in the first 2 years after diagnosis and treatment. More research is needed to gain knowledge about reasons for drinking and causality.

Does alcohol affect emotional face processing via interoceptive pathways?

BACKGROUND

Our brain uses interoceptive signals from the body to shape how we perceive emotions in others; however, whether interoceptive signals can be manipulated to alter emotional perceptions is unknown. Alcohol has acute effects both on emotional processing and on the physiological substrates supporting interoception. In this registered report, we examine whether alcohol administration triggers physiological changes that alter interoceptive signals and manipulate emotional face processing. Such knowledge will broaden understanding of the mechanisms by which alcohol affects emotional face processing.

METHODS

Participants (n = 36) will be administered an alcohol or placebo beverage. Cardiovascular physiology will be recorded before and after administration. Participants will complete two behavioral tasks in which they view emotional faces presented in synchrony with different phases of the cardiac cycle (i.e., systole, diastole). This manipulation creates an index of how interoceptive signals amplify emotional face processing.

HYPOTHESES

We hypothesize that, compared to placebo, alcohol administration will disrupt the cardiac amplification of emotional face processing. We further explore whether this disruption depends on the nature and magnitude of changes in cardiovascular physiology after alcohol administration.

The effect of alcohol on mood among males drinking with a platonic friend

BACKGROUND

Despite the social nature of most drinking experiences, prior work has largely failed to incorporate social context into the study of alcohol's effects on emotion. The present study provides an initial test of the effect of alcohol on mood among platonic friends drinking together in a non-stress setting. We hypothesized that subjects would report more positive postdrink mood after consuming alcohol than after consuming a nonalcoholic control beverage.

METHODS

Dyads of platonic male friends (n = 36; 55.55% White, 38.88% Asian, 5.55% Black) attended two laboratory-based experimental sessions, wherein their drink conditions (alcohol vs. no alcohol control) were randomized by dyad and counter-balanced across sessions. They reported their mood before and after consuming their beverages together, using the Positive and Negative Affect Schedule and an 8-item mood measure.

RESULTS

As hypothesized, alcohol enhanced positive mood ( β  = 0.26, p < 0.01). Although in the expected direction, the effect of alcohol on negative mood was not significant ( β  = -0.12, p = 0.17). Post hoc analyses revealed that alcohol yielded greater increases in both stimulation ( β = 0.26 , p = 0.00) and sedation ( β = 0.40 , p = 0.00) as compared to the control condition.

CONCLUSION

This study highlights the positive mood-enhancing and broader subjective effects of alcohol when drinking with a platonic friend and encourages further consideration of friendship contexts in the examination of alcohol's effects when developing models of the etiology of alcohol use disorder.

Beneficial Effects of Betaine: A Comprehensive Review

Medicinal herbs and many food ingredients possess favorable biological properties that contribute to their therapeutic activities. One such natural product is betaine, a stable, nontoxic natural substance that is present in animals, plants, and microorganisms. Betaine is also endogenously synthesized through the metabolism of choline or exogenously consumed through dietary intake. Betaine mainly functions as (i) an osmolyte and (ii) a methyl-group donor. This review describes the major physiological effects of betaine in whole-body health and its ability to protect against both liver- as well as non-liver-related diseases and conditions. Betaine's role in preventing/attenuating both alcohol-induced and metabolic-associated liver diseases has been well studied and is extensively reviewed here. Several studies show that betaine protects against the development of alcohol-induced hepatic steatosis, apoptosis, and accumulation of damaged proteins. Additionally, it can significantly prevent/attenuate progressive liver injury by preserving gut integrity and adipose function. The protective effects are primarily associated with the regulation of methionine metabolism through removing homocysteine and maintaining cellular SAM:SAH ratios. Similarly, betaine prevents metabolic-associated fatty liver disease and its progression. In addition, betaine has a neuroprotective role, preserves myocardial function, and prevents pancreatic steatosis. Betaine also attenuates oxidant stress, endoplasmic reticulum stress, inflammation, and cancer development. To conclude, betaine exerts significant therapeutic and biological effects that are potentially beneficial for alleviating a diverse number of human diseases and conditions.

Training emotion regulation processes in alcohol-abstinent individuals: A pilot study

The study aimed to assess whether abstinent individuals with alcohol use disorders (AUD) would benefit from enhanced emotional regulation (ER) strategies using the affect regulation training (ART) program based on weekly sessions comprising psycho-education, muscle and respiratory relaxation, awareness, acceptance and tolerance, compassionate personal support, emotion analysis and modification. Seventy-two participants with AUD benefited from ART and were compared on their ER ability, mindfulness, and their experience of abstinence to 40 participants not receiving the program, before it, at the end, and 6 months after. Improvements in ER were observed, particularly in positive centration, action centration or self-blame and in mindfulness abilities after the program and six months later. In addition, by comparing participants who received the program with a short (<18 months) or long (>18 months) abstinence duration, the results showed a greater decrease in the use of non-adaptive strategies, a greater increase in adaptive strategies and mindfulness abilities in short-term abstinent individuals. These results demonstrate improvement in ER skills after training in people who were abstinent from alcohol. ART is effective for consolidating abstinence and should be used especially at the beginning of withdrawal to promote the rapid implementation of new ER strategies.

The Prevalence of Depressive and Insomnia Symptoms, and Their Association With Quality of Life Among Older Adults in Rural Areas in China

Background: There are few studies on the epidemiology of depression, insomnia, and their association with quality of life (QOL) in older adults living in rural China. This study examined the prevalence of depressive and insomnia symptoms, and their association with QOL in community-dwelling older adults in a rural area in Anhui province, China. Methods: This was a cross-sectional study conducted in the rural areas of four cities (Hefei, Huaibei, Anqing, and Xuancheng) in Anhui province between July and October, 2019 using random sampling method. All community-dwelling residents from the selected villages who met the study entry criteria were invited to participate in this study. Depressive and insomnia symptoms and QOL were assessed with the Chinese version of self-reported Center for Epidemiological Survey Depression Scale (CES-D), the Insomnia Severity Index (ISI) and the 26-item World Health Organization Quality of Life Brief version (WHOQOL-BREF), respectively. Results: A total of 871 older adults were included. The prevalence of overall depressive symptoms, insomnia symptoms, and comorbid depressive and insomnia symptoms were 34.0% [95% confidence intervals (95% CI): 30.8-37.1%], 45.7% (95% CI: 42.4-49.0%) and 20.3% (95% CI: 17.6-23.0%), respectively. Older adults with depressive symptoms, insomnia symptoms, and comorbid depressive and insomnia symptoms had lower scores in QOL compared to those without. Depressive symptoms were positively associated with living with families [Odd Ratio (OR) = 1.82, 95% CI: 1.31-2.54] and negatively associated with current drinking (OR = 0.49, 95% CI: 0.33-0.72). Insomnia symptoms were negatively associated with fair and good financial status (fair: OR = 0.53, 95% CI = 0.38-0.75; good: OR = 0.30, 95% CI = 0.14-0.64) and current drinking (OR = 0.64, 95% CI = 0.45-0.93), and positively associated with more frequent major medical conditions (OR = 1.32, 95% CI = 1.16-1.51). Comorbid depressive and insomnia symptoms were positively associated with living with families (OR = 2.02, 95% CI = 1.36-3.00), and negatively associated with fair and good financial status (fair: OR = 0.61, 95% CI = 0.41-0.89; good: OR = 0.34, 95% CI = 0.12-0.95) and current drinking (OR = 0.57, 95% CI = 0.35-0.92). Conclusion: Depressive and insomnia symptoms were common in older adults living in rural areas in China. Considering the negative health outcomes caused by depressive and insomnia symptoms, regular screening and effective treatments should be developed for this population.

Acute effects of alcohol on error-elicited negative affect during a cognitive control task

RATIONALE

Alcohol intoxication can dampen negative affective reactions to stressors. Recently, it has been proposed that these acute anxiolytic effects of alcohol may extend to dampening of negative affective reactions to error commission during cognitive control tasks. Nonetheless, empirical verification of this claim is lacking.

OBJECTIVES

Test the acute effect of alcohol on negative affective reactions to errors during an effort-demanding cognitive control task.

METHODS

Healthy, young adult social drinkers (N = 96 [49 women], 21-36 years old) were randomly assigned to consume alcohol (0.80 g/kg; n = 33 [15 female]), active placebo (0.04 g/kg; n = 33 [18 women]), or a non-alcoholic control beverage (n = 30 [16 women]) before completing the Eriksen flanker task. Corrugator supercilii (Corr) activation, a psychophysiological index of negative affect, was tracked across the task. Two neurophysiological reactions to errors, the error-related negativity (ERN) and the error positivity (Pe), were also measured.

RESULTS

Erroneous actions increased Corr activation in the control and (to a lesser extent) placebo groups, but not in the alcohol group. Error-induced Corr activation was coupled to ERN and Pe in the control, but not in the alcohol and placebo groups. Error-induced Corr activation was not coupled to post-error performance adjustments in any group.

CONCLUSIONS

The ability of alcohol to dampen error-related negative affect was verified. It was also shown that placebo alone can disrupt coupling of affective and (neuro)cognitive reactions to errors. Although its behavioral relevance remains to be demonstrated, more attention should be paid to the role of affect in action monitoring and cognitive control processes.

Stop! - The automatic tendency of action, inhibition and frontal activation in individuals with alcohol-use disorder in abstinence

Studying the functioning of the frontal lobe during the performance of an inhibitory activity according to automatic tendency of action would allow a better understanding of the relationship between the reflexive and impulsive system described in the dual-process models. This study aims to prove which is the inhibitory capacity and the underlying brain activity of people with alcohol-use disorder in abstinence with a greater avoidance tendency compared to those with a higher approach tendency and healthy controls. In order to group participants with AUD, the total approach/avoidance index (TAAI) - obtained from the modified alcohol approach/avoidance task - was used, therefore resulting in three groups: TAAI- (TAAI < Percentile 35: n = 20), TAAI± (TAAI = Percentile 35-65: n = 20) and TAAI+ (TAAI > Percentile 65: n = 20). In addition to this, 15 healthy controls were recruited. They all had an electroencephalographic recording while completing the modified stop-signal task. The results showed that the TAAI+ group had a worse inhibition compared to healthy controls. Moreover, the TAAI+ group showed a hyperactivation of the inferior frontal gyrus, precentral gyrus and orbital gyrus compared to the healthy controls group and the TAAI- group. The results obtained reflect that those people with AUD with a tendency to approach alcohol have a worse inhibitory capacity and a frontal hyperactivation. Moreover, people with AUD with an avoidance tendency to alcohol have also been found to have a similar inhibitory capacity and frontal activation to healthy controls.

Changes in Diet, Sleep, and Physical Activity Are Associated With Differences in Negative Mood During COVID-19 Lockdown

The United Kingdom and Scottish governments instigated a societal lockdown in response to the COVID-19 pandemic. Subsequently, many experienced substantial lifestyle changes alongside the stresses of potentially catching the virus or experiencing bereavement. Stressful situations and poorer health behaviors (e.g., higher alcohol consumption, unhealthy diet, poorer sleep quality, physical inactivity) are frequently linked to poor mental health. Our objective was to examine changes in health behaviors and their relationship with negative mood during COVID-19 lockdown. We also considered associations between health behaviors and socio-demographic differences and COVID-19-induced changes. 399 participants completed a questionnaire asking about their personal situation and health behaviors during lockdown as well as a negative mood scale. The significance threshold for all analyses was α = 0.05. Poorer diet was linked to more-negative mood, and to changes to working status. Poorer sleep quality was linked with more-negative mood, and with 'shielding' from the virus. Being less physically active was related to more-negative mood and student status, whereas being more physically active was linked to having or suspecting COVID-19 infection within the household. Increased alcohol consumption was linked to living with children, but not to negative mood. Changes to diet, sleep quality, and physical activity related to differences in negative mood during COVID-19 lockdown. This study adds to reports on poor mental health during lockdown and identifies lifestyle restrictions and changes to health behaviors which may, to some extent, be responsible for higher negative mood. Our data suggests that it is advisable to maintain or improve health behaviors during pandemic-associated restrictions.

The Impact of Mood and Subjective Intoxication on Hangover Severity

The aim of this study was to investigate whether baseline mood and/or mood while drinking have an impact on alcohol hangover severity. A survey was held among N = 331 young adults (mean age = 23.6 years, range = 18-35 years). Demographics, alcohol consumption, subjective intoxication, and hangover severity were assessed for the past three days. In addition, mood (baseline, while drinking, and during hangover) was also assessed. N = 143 participants reported to be hungover on the day of assessment, N = 122 participants reported to have been hungover the previous day ('yesterday'), and N = 87 participants reported to have been hungover two days before the assessment ('2 days ago'). The analyses revealed that baseline mood and mood while drinking had no relevant effect on the amount of consumed alcohol and did not significantly contribute to hangover severity. However, hangover severity was associated with significantly increased negative affect, particularly with higher levels of subjective stress on the day of the hangover.

Acute alcohol effects on conditioned pain modulation, but not temporal summation of pain

Although pain reduction after alcohol administration has repeatedly been demonstrated, alcohol effects on advanced and clinically relevant dynamic pain paradigms are still unknown. As such, temporal summation of pain (TSP) and conditioned pain modulation (CPM) indicate mechanisms of endogenous pain modulation and involve certain neurotransmitter systems crucially influenced by alcohol. Our study is the first to investigate acute alcohol effects on TSP and CPM. We investigated 39 healthy subjects in a placebo-controlled within-subject design and targeted alcohol levels of 0.06% (dose 1) and 0.08% (dose 2). Pain threshold, TSP, and CPM were evaluated before and after an alcoholic or placebo drink. Temporal summation of pain was assessed as enhanced pain response to 5 repetitive contact heat stimuli (threshold +3°C). Conditioned pain modulation was tested as pain inhibition when a conditioning stimulus (46°C hot water) was applied concurrently to a test stimulus (contact heat; threshold + 3°C). Both alcohol doses boosted CPM, with a greater effect size for the higher dose. Conditioning stimulus ratings increased after alcohol intake but were not correlated with CPM, suggesting independence of these effects. Temporal summation of pain was not affected by alcohol, and alcohol effects on pain threshold were small and limited to the higher dose. Our findings suggest that analgesic alcohol effects might be mainly driven by an enhancement of endogenous pain inhibition. The frequent use of alcohol as self-medication in chronic pain might be motivated by alcohol temporarily restoring deficient CPM, thus leading to pain relief in the short run and alcohol-related problems in the long run.

An examination of the extent to which mood and context are associated with real-time alcohol consumption

AIM

To assess the effects of mood, social and environmental contexts and alcohol-related beliefs on alcohol consumption.

METHOD

Participants (N = 69) recorded their positive and negative outcome expectancies and self-reported mood prior to drinking (Time 1 mood). A Smartphone App then enabled alcohol consumption (total number of drinks aggregated from reports throughout a drinking occasion, current mood (Time 2 mood), social context e.g., with friends and environmental location e.g., in a bar/pub to be documented in de facto real-time a total of 3009 data points.

RESULTS

Feeling unhappy prior to consumption onset was associated with a significant increase in drinking. During a drinking occasion, feeling happy was a significant predictor of drinking larger quantities. Interestingly, however, an interaction between T1 and T2 mood suggested it is not mood prior to consumption which drives drinking, but rather that alcohol consumption elevates mood. Being with two or more friends (relative to being alone) also predicted increased consumption. Positive and negative expectancies were not found to be significant predictors within these models.

CONCLUSION

By showing that both mood and social context may shape alcohol behaviors distinctly, the current study suggests that alcohol research and intervention efforts may benefit from greater consideration of the temporally-mediated contextual influences on alcohol consumption.

Early Signs of Emotional Recognition Deficits in Adolescent High-Binge Drinkers

Background: Emotional dysregulation, measured with face recognition tasks, is prevalent in alcohol use disorders (AUD), constituting a risk factor for alcohol use and relapse. It is not clear however whether emotional dysregulation is a by-product of alcohol consumption, or if it can act as a predisposing factor for AUD. Objective: Our aim was to examine early signs of emotional dysregulation in adolescent drinkers. Method: Twenty-four high-school students and 24 university students completed two tasks. On the first one, participants had to gradually increment the emotional content of different faces until they could perceive an emotional expression (emotion perception threshold task). We also examined the propensity to perceive fearful expressions in an emotion identification task. Participants were semantically primed with emotion words (i.e., "fear"), and they then had to indicate whether a neutral-fearful facial composite matched the prime. Results: Using repeated-measures ANOVAS, in the emotion perception threshold task, "happy" faces were the easiest to detect and "sad" ones the hardest. For high school students there was a differential response pattern depending on binge scores, such that High-binge drinkers found it easier to detect a sad face but harder to detect a happy one compared to Low-binge drinkers. In the facial emotion identification task, Low-binge drinkers observed more fearful expressions compared to High-binge drinkers. Conclusions: Differences in emotional processing in young adolescents depending on drinking habits point towards the relevance of emotional dysregulation as an early sign of AUD. These findings could help develop novel diagnostic and treatment tools for young populations.

Alcohol Consumption in China Before and During COVID-19: Preliminary Results From an Online Retrospective Survey

Background: Alcohol is an important aspect of Chinese culture, and alcohol use has been traditionally accepted in China. People with stress, anxiety, and depression may use more alcohol. More people reported symptoms of anxiety and depression during the outbreak of COVID-19. Thus, people may drink more alcohol during the outbreak of COVID-19 than before COVID-19. Methods: An online retrospective survey was conducted on a total sample of 2,229 participants. Drinking behaviors before and during COVID-19, current risky drinking and hazardous drinking, and the association between high-risk drinking and mental health problems (depression, anxiety, and stress) were assessed via self-reported measures on the Alcohol Use Disorders Identification Test (AUDIT) and the 21-item Depression Anxiety Stress Scales (DASS-21). Results: This study found that, compared with before COVID-19, alcohol consumption was slightly decreased during COVID-19 (from 3.5 drinks to 3.4 drinks, p = 0.035) in the overall sample. Most (78.7%) alcohol drinkers were males. Before and during COVID-19, males consumed more drinks per week (4.2 and 4.0 vs. 1.3 and 1.2 drinks), had a higher percentage of heavy drinking (8.1 and 7.7% vs. 4.4 and 2.7%), and more drinking days per week (2.1 and 2.1 vs. 1.0 and 0.9 days). Males also had more risky drinking (43.2 vs. 9.3%) and hazardous drinking (70.2 vs. 46.6%) than female counterparts. This study also found that high-risk drinking predicted anxiety in females. Conclusions: This study suggests a slight reduction in alcohol consumption during COVID-19. However, hazardous drinking is common, especially among male alcohol drinkers. Males consumed more alcohol, had more risky and hazardous drinking than female counterparts both before and during COVID-19. Public health policy makers should pay more attention to developing effective, population-based strategies to prevent harmful alcohol consumption.

Don't drink and chill: Effects of alcohol on subjective and physiological reactions during music listening and their relationships with personality and listening habits

Recent research indicates that favorite music can induce chills and alters physiological reactions. People frequently listen to music when they drink alcohol, for example in bars or discotheques. Alcohol has numerous effects on emotions, peripheral physiological and neural reactions. We investigated whether alcohol intake influences chill experiences and physiological reactions during music listening. 39 participants took part in the study and were tested twice: Once in a sober condition and once when they had drunken alcohol. Participants listened to two pieces of music in each of the two conditions: A favorite self-selected song and a control-song that was selected by the research group. Participants had to indicate when they experienced a chill and electrodermal activity and heart rate were measured during music listening. In addition, participants filled out questionnaires concerning the big five personality dimensions, music listening habits and general chill experiences. Results indicate that participants experienced most chills when they were sober and listened to their self-selected song. Electrodermal activity was highest when participants were sober. In addition, alcohol intake led to a dedifferentiation in heart rate activity. After alcohol intake, participants had similar heart rates, no matter whether they listened to their self-selected song or to the control-song. Extraversion was negatively related with physiological reactions, while openness to experiences was positively related with physiological reactions. Music listening habits also showed various relationships with chill experiences and physiological reactions, while general chill experiences did not. We conclude that alcohol intake reduces subjective chill experiences during music listening and alters the physiological reactions to music. Music listening habits and personality seem to influence these effects.
