Anxiety and depression in alcohol use disorder individuals: the role of personality and coping strategies

Exploring the role of fear of missing out in coping and risk-taking among alcohol use disorder and general young adult populations

A high level of fear of missing out (FOMO) is related to many adverse emotions and behaviors, including stress, maladaptive coping, risk-taking, and alcohol consumption. However, previous research on FOMO has not considered particularly vulnerable cohorts like individuals with alcohol use disorder (AUD). In this project, we have conducted two preliminary studies (N1 = 356; N2 = 66) investigating the role of FOMO in alcohol-related coping strategy in a general population of young adults as well as a clinical sample of AUD patients. Results showed that FOMO is a positive predictor of alcohol coping in both studied samples, and it is a positive predictor of health risk-taking among people with AUD. The study identifies high FOMO as a risk factor for adopting maladaptive coping strategies, specifically alcohol coping.

Liraglutide Reduces Alcohol Consumption, Anxiety, Memory Impairment, and Synapse Loss in Alcohol Dependent Mice

Glucagon-like peptide 1 (GLP-1) analogues have been commercialized for the management of type 2 diabetes. Recent studies have underscored GLP-1's role as a modulator of alcohol-related behavior. However, the role of the GLP-1 analogue liraglutide on alcohol-withdrawal responses have not been fully elucidated. Liraglutide binds to the G-protein-coupled receptor and activates an adenylyl cyclase and the associated classic growth factor signaling pathway, which acts growth factor-like and neuroprotective properties. The underlying neurobiological mechanisms of liraglutide on alcohol withdrawal remains unknown. This study endeavored to explore the effects of liraglutide on the emotion and memory ability of alcohol-withdrawal mice, and synaptic morphology in the medial prefrontal cortex (mPFC) and the hippocampus (HP), and thus affects the relapse-like drinking of alcohol-withdrawal mice. The alcohol-withdrawal group was reintroduced to a 20% v/v alcohol and water through the two-bottle choice for four consecutive days, a period referred to as alcohol re-drinking. Male C57BL/6J mice were exposed to a regimen of 20% alcohol and water for a duration of 6 weeks. This regimen established the two-bottle choice model of alcohol exposure. Learning capabilities, memory proficiency, and anxiety-like behavior were evaluated using the Morris water maze, open field, and elevated plus maze paradigms. Furthermore, synaptic morphology and the levels of synaptic transport-related proteins were assessed via Golgi staining and Western Blot analysis after a two-week alcohol deprivation period. Alcohol re-drinking of alcohol-withdrawal mice was also evaluated using a two-bottle choice paradigm. Our findings indicate that liraglutide can substantially decrease alcohol consumption and preference (p < 0.05) in the alcohol group and enhance learning and memory performance (p < 0.01), as well as alleviate anxiety-like behavior (p < 0.01) of alcohol-withdrawal mice. Alcohol consumption led to a reduction in dendritic spine density in the mPFC and HP, which was restored to normal levels by liraglutide (p < 0.001). Furthermore, liraglutide was found to augment the levels of synaptic transport-related proteins in mice subjected to alcohol withdrawal (p < 0.01). The study findings corroborate that liraglutide has the potential to mitigate alcohol consumption and ameliorate the memory impairments and anxiety induced by alcohol withdrawal. The therapeutic efficacy of liraglutide might be attributed to its role in counteracting synapse loss in the mPFC and HP regions and thus prevented relapse-like drinking in alcohol-withdrawal mice.

A role for circuitry of the cortical amygdala in excessive alcohol drinking, withdrawal, and alcohol use disorder

Alcohol use disorder (AUD) poses a significant public health challenge. Individuals with AUD engage in chronic and excessive alcohol consumption, leading to cycles of intoxication, withdrawal, and craving behaviors. This review explores the involvement of the cortical amygdala (CoA), a cortical brain region that has primarily been examined in relation to olfactory behavior, in the expression of alcohol dependence and excessive alcohol drinking. While extensive research has identified the involvement of numerous brain regions in AUD, the CoA has emerged as a relatively understudied yet promising candidate for future study. The CoA plays a vital role in rewarding and aversive signaling and olfactory-related behaviors and has recently been shown to be involved in alcohol-dependent drinking in mice. The CoA projects directly to brain regions that are critically important for AUD, such as the central amygdala, bed nucleus of the stria terminalis, and basolateral amygdala. These projections may convey key modulatory signaling that drives excessive alcohol drinking in alcohol-dependent subjects. This review summarizes existing knowledge on the structure and connectivity of the CoA and its potential involvement in AUD. Understanding the contribution of this region to excessive drinking behavior could offer novel insights into the etiology of AUD and potential therapeutic targets.

Adverse Childhood Experiences, Coping and Resilience in Persons with Alcohol Use Disorder and Their Non-drinking Siblings in High-density Families: A Case-control Study

Background

Adverse childhood experiences (ACEs) increase the odds of alcohol use disorder (AUD).

Aim

To study the ACEs, coping, and resilience in persons with AUD and their non-drinking siblings from high-density families.

Methods

The study used a case-control study design. Using purposive sampling, 135 participants were selected; the sample consists of persons with AUD (n = 45), non-drinking siblings (n = 45), and healthy controls (n = 45), selected from out-patient and in-patient services from a government-run de-addiction centre in Bengaluru. Individuals were administered an ACEs questionnaire, Brief-COPE, and Connor-Davison Resilience scale. Descriptive statistics, Friedman's test, and Bonferroni's post-hoc test, Binary Logistic Regression were used for analysis.

Results

ACEs, coping, and resilience significantly differ across the three groups. Persons with AUD and their non-drinking siblings are comparable in terms of ACEs and having dysfunctional family members. Non-drinking siblings and healthy controls have similar coping and resilience. None of the healthy controls had dysfunctional family members.

Conclusion

ACEs are more prevalent and more frequent in persons with AUD. Individuals with AUD showed higher avoidant coping and lower resilience than their non-drinking siblings and healthy controls. Early identification of ACEs and interventions to build resilience and coping strategies could prevent individuals from developing AUD in high-density families.

Rare and Common Variants Associated with Alcohol Consumption Identify a Conserved Molecular Network

Genome-wide association studies (GWAS) have identified hundreds of common variants associated with alcohol consumption. In contrast, rare variants have only begun to be studied for their role in alcohol consumption. No studies have examined whether common and rare variants implicate the same genes and molecular networks. To address this knowledge gap, we used publicly available alcohol consumption GWAS summary statistics (GSCAN, N=666,978) and whole exome sequencing data (Genebass, N=393,099) to identify a set of common and rare variants for alcohol consumption. Gene-based analysis of each dataset have implicated 294 (common variants) and 35 (rare variants) genes, including ethanol metabolizing genes ADH1B and ADH1C, which were identified by both analyses, and ANKRD12, GIGYF1, KIF21B, and STK31, which were identified only by rare variant analysis, but have been associated with related psychiatric traits. We then used a network colocalization procedure to propagate the common and rare gene sets onto a shared molecular network, revealing significant overlap. The shared network identified gene families that function in alcohol metabolism, including ADH, ALDH, CYP, and UGT. 74 of the genes in the network were previously implicated in comorbid psychiatric or substance use disorders, but had not previously been identified for alcohol-related behaviors, including EXOC2, EPM2A, CACNB3, and CACNG4. Differential gene expression analysis showed enrichment in the liver and several brain regions supporting the role of network genes in alcohol consumption. Thus, genes implicated by common and rare variants identify shared functions relevant to alcohol consumption, which also underlie psychiatric traits and substance use disorders that are comorbid with alcohol use.

The Influence of Anxiety and Avoidant Coping on Probable Cannabis Use Disorder

Objective

Individuals with anxiety frequently use cannabis to cope and are at greater risk for developing probable cannabis use disorder (CUD). Previous literature suggests avoidant coping styles are associated with higher anxiety levels and risk for problematic cannabis use, while action-oriented coping is associated with lower anxiety and problematic cannabis use. No studies have examined whether anxiety and action-oriented coping or avoidant coping interact to influence risk for CUD, which was the aim of the present study.

Method

College students were recruited as part of a cross-sectional study on cannabis use. Participants (N = 371; 72.2% female) completed the Depression Anxiety and Stress Subscale (DASS-21), Cannabis Use Disorder Identification Test-Revised (CUDIT-R), and the Brief-COPE (B-COPE).

Results

The data were analyzed using logistic moderation analysis. After controlling for gender, anxiety was a positive significant predictor of probable CUD, but action-oriented coping and avoidant coping were not. The interaction between anxiety and avoidant coping on probable CUD was significant, indicating that participants with high avoidant coping (regardless of high or low anxiety) and those with high anxiety (even with low avoidant coping) were more likely to have probable CUD than those with both low anxiety and low avoidant coping. No significant interaction was observed with action-oriented coping.

Conclusions

Results suggest that avoidant coping, but not action-oriented coping, influences the relationship between anxiety and risk for probable CUD. Findings emphasize the importance of targeting both anxiety and avoidant coping when considering risk for probable CUD.

Problem-Focused Coping and Teacher Emotional Violence: A Serial Mediation Analysis

Although school violence is a serious problem, teacher emotional violence that has short- and long-term detrimental effects on children's development is often overlooked. Considering the potential negative effects, it is important to determine teacher characteristics associated with teacher emotional violence, especially in societies where the prevalence rate of emotional violence is high. The current study investigated the role of teacher stress and burnout and favorable attitudes toward emotional violence in the association between problem-focused coping and teacher emotional violence. Between February and June 2019, a cross-sectional study was conducted in 16 randomly selected secondary schools in İzmir, Turkey. In total, 205 secondary school teachers (64.4% females, Mage = 37.20 years) participated in this study. Participants completed questionnaires that assessed their use of emotional violence, favorable attitudes toward emotional violence, stress and burnout, and problem-focused coping. A serial mediation model was conducted. The model indicated that problem-focused coping was not directly associated with teacher emotional violence. Examination of indirect pathways suggested that favorable attitudes toward emotional violence did not mediate this relationship; however, stress and burnout mediated the link between problem-focused coping and emotional violence. In addition, there was a significant indirect effect from problem-focused coping to emotional violence through stress and burnout and favorable attitudes toward emotional violence. The findings indicate a potential role of teacher characteristics in preventing teacher emotional violence.

BDNF CpG methylation and serum levels covary during alcohol withdrawal in patients with alcohol use disorder: A pilot study

OBJECTIVES

Brain-derived neurotrophic factor (BDNF) levels vary in various conditions including alcohol use disorder (AUD). We aimed to identify drivers of these variations.

METHODS

Twelve patients with AUD were assessed at hospitalisation for alcohol withdrawal and four months later. We looked for associations between the change in serum BDNF levels and (1) length of abstinence, (2) anxiety (Hamilton Anxiety Scale) and depression (Beck-Depression Inventory), (3) one functional BDNF genotype (rs6265) and (4) methylation levels of 12 CpG sites within the BDNF gene (located in exons I, IV and IX).

RESULTS

While abstinence remained, serum BDNF level increased. This increase correlated with the variation of methylation levels of the BDNF gene, and more specifically of exon I. We found no significant effect of length of abstinence, rs6265, depression or anxiety on serum BDNF level.

CONCLUSIONS

Epigenetic regulation of the BDNF gene may be involved in variations of BDNF blood level associated with alcohol abstinence.

Predicting Alcohol-Related Memory Problems in Older Adults: A Machine Learning Study with Multi-Domain Features

Memory problems are common among older adults with a history of alcohol use disorder (AUD). Employing a machine learning framework, the current study investigates the use of multi-domain features to classify individuals with and without alcohol-induced memory problems. A group of 94 individuals (ages 50-81 years) with alcohol-induced memory problems (the memory group) were compared with a matched control group who did not have memory problems. The random forests model identified specific features from each domain that contributed to the classification of the memory group vs. the control group (AUC = 88.29%). Specifically, individuals from the memory group manifested a predominant pattern of hyperconnectivity across the default mode network regions except for some connections involving the anterior cingulate cortex, which were predominantly hypoconnected. Other significant contributing features were: (i) polygenic risk scores for AUD, (ii) alcohol consumption and related health consequences during the past five years, such as health problems, past negative experiences, withdrawal symptoms, and the largest number of drinks in a day during the past twelve months, and (iii) elevated neuroticism and increased harm avoidance, and fewer positive "uplift" life events. At the neural systems level, hyperconnectivity across the default mode network regions, including the connections across the hippocampal hub regions, in individuals with memory problems may indicate dysregulation in neural information processing. Overall, the study outlines the importance of utilizing multidomain features, consisting of resting-state brain connectivity data collected ~18 years ago, together with personality, life experiences, polygenic risk, and alcohol consumption and related consequences, to predict the alcohol-related memory problems that arise in later life.

Personality traits associated with Alcohol Dependence Syndrome and its relapse

Background

Course of Alcohol Dependence Syndrome (ADS) is studded with multiple relapses. Personality factors are implicated as one of the influencing factors in the course of this disorder. Keeping in view of scarcity of Indian data available, the study was planned with the aim to find Personality traits more commonly associated with ADS patients, and identify specific traits, associated with relapses of ADS.

Method

With sample size of 100 consecutive cases and 100 controls, socio-demographic data was collected. Alcohol Use Disorder Identification Test (AUDIT) and Severity of Alcohol Use Disorder Test (SAD-Q) were administered to each of these patient. Personality dimensions were assessed with NEO-five factor inventory (NEO-FFI) (Costa and McCrae), for both groups and further compared for differences in the dimensions in each of its subscale.

Results

The NEO scores, showed statistically significant difference with Cases having higher scores in Neuroticism and control group in Openness and Conscientiousness. Neuroticism linked to higher scores of AUDIT and SADQ and also associated with relapses. Other traits also showed statistically significant association which are discussed.

Conclusion

As new factors are being explored for effective management, routine personality profiling is easily accomplished and can give delightful insight into focused and designed management plan.

[Drinking behavior at the beginning and during the SARS-CoV-2 pandemic: results of a literature review]

Background and objective

It is well known that alcohol consumption and abuse, as well as alcohol-induced problems, increase during difficult economic times. Previous studies showed increased alcohol consumption in the 2003 SARS outbreak in China. The review examines global changes in alcohol consumption under current SARS-CoV‑2 (severe acute respiratory syndrome coronavirus 2) pandemic.

Materials and methods

The databases PubMed, Ovid, Cochrane Library, Scopus, PsycINFO, and Web of Science with a cut-off date of 11 January 2022 were used. An initial hit count of 791 publications was found. After reading the title and abstract, 62 texts were still eligible. After reviewing the full text, 40 studies were included in this review.

Results

Study results were available from North and South America, Europe, Asia and Oceania. Increases as well as reductions in alcohol consumption were shown. Studies examining multiple waves of the pandemic found that alcohol consumption increased with duration of the pandemic. Binge drinking played a large role in this. There were very large regional differences in the increase in alcohol consumption: from about 10% of respondents to > 45%. In most studies, alcohol consumption was about the same for 40-50% of respondents and decreased for 30-40%.

Conclusions

Further study follow-ups under the continuing pandemic are relevant. Since the populations studied were predominantly of working age, occupational prevention measures of elevated stress levels for some of the respondents with increased alcohol consumption seem reasonable.

The diagnostic and predictive potential of personality traits and coping styles in major depressive disorder

BACKGROUND

Major depressive disorder (MDD) is a global public health concern that is notably underdiagnosed and undertreated due to its complexity and subjective diagnostic methods. A holistic diagnostic procedure, which sufficiently considers all possible contributors to MDD symptoms, would improve MDD diagnosis and treatment. This study aims to explore whether personality and coping styles can predict MDD status and differentiate between depressed patients and healthy individuals.

METHODS

Seventy healthy controls (N = 54 females) were matched to 70 MDD patients for age, sex, ethnicity, and years of education. MDD severity was measured using the Hamilton Depression Rating Scale, while personality traits and coping styles were measured by the Ten-Item Personality (TIPI) and Brief COPE questionnaires, respectively. Logistic regression analyses were conducted to investigate the diagnostic and predictive potential of personality and coping styles. Receiver operating characteristic (ROC) analyses were also conducted to examine their discriminative ability to distinguish between depressed and healthy individuals.

RESULTS

Introversion, lack of organisation skills, and neuroticism were statistically significant in predicting MDD status. Dysfunctional coping strategies, such as denial and self-blame, were also shown to significantly predict MDD status. ROC analyses found both the TIPI questionnaire (AUC = 0.90), and dysfunctional coping (as measured by Brief COPE) (AUC = 0.90) to be excellent predictors of MDD.

CONCLUSIONS

Our findings demonstrate the diagnostic and predictive potential of personality and coping styles for MDD in the clinical setting. They also demonstrate the remarkable ability of personality and coping styles to differentiate between depressed patients and healthy controls.

Does receiving an eating disorder diagnosis increase the risk of a subsequent alcohol use disorder? A Danish nationwide register-based cohort study

BACKGROUND AND AIM

No large-scale, longitudinal clinical study has examined whether patients with different types of eating disorders (ED) have an increased risk of a subsequent alcohol use disorder (AUD). This study aimed to assess the ongoing risk of receiving a diagnosis of AUD following a first-time diagnosis of anorexia nervosa (AN), bulimia nervosa (BN), or unspecified ED (USED).

DESIGN

Retrospective cohort study.

SETTING

Danish nationwide registries, January 1994 to December 2018.

PARTICIPANTS

A total of 20 759 ED patients and 83 036 controls were followed from the date of first ED diagnosis (index date) until the date of first AUD diagnosis, death, emigration, or the end of the study. Controls were selected in a 1:4 ratio and matched on month and year of birth, gender and ethnicity.

MEASUREMENTS

We obtained data on ED (AN, BN, USED; exposure) and AUD (abuse/dependence; outcome) diagnoses as well as sociodemographics and other psychiatric diagnoses. Time to AUD was generated from the index date. Risk of AUD after the index date was assessed among those without a prior AUD diagnosis while adjusting for sociodemographics and prior psychiatric diagnoses.

FINDINGS

Compared with controls, an increased relative risk of AUD after the index date was observed in AN patients throughout the study lasting 15 + years (adjusted hazard ratios [HRs] ranging from 2.49 [99% CI = 1.46, 4.25] to 6.83 [2.84, 16.41]), in BN patients during the first year of follow-up and from 2 years onward (2.72 [1.66, 4.44] to 17.44 [6.01, 50.63]), and in USED patients during the first year and 2-15 years of follow-up (2.52 [1.54, 4.14] to 14.17 [5.86, 34.27]). In all three groups, estimates were highest during the first year, particularly among BN patients.

CONCLUSIONS

Patients with anorexia nervosa, bulimia nervosa, or unspecified eating disorders appear to have an increased ongoing risk of receiving a diagnosis of alcohol use disorder following their first eating disorder diagnosis compared with controls.

Three Mediating Pathways of Anxiety and Security in the Relationship between Coping Style and Disordered Eating Behaviors among Chinese Female College Students

Background

According to previous studies, eating disorders and disordered eating behaviors are associated with coping style, anxiety, and sense of security. However, the specific mechanism between them has not been elucidated. The purpose of this study was to explore whether anxiety and sense of security play mediating roles in coping style and disordered eating behaviors among Chinese female college students.

Method

Six hundred and ninety-one female college students (mean age = 19.36; SD = 1.06) completed the Simple Coping Style Questionnaire, the Eating Disorder Inventory, the Security Questionnaire, the Hospital Anxiety and Depression Scale, and a brief demographic survey. The percentage bootstrap method of deviation correction was conducted to determine the mediating effect of anxiety and sense of security on coping style and disordered eating behaviors.

Results

Coping style had direct and indirect effects on disordered eating behaviors. Anxiety and sense of security were not only independent mediators in the relationship between coping style and disordered eating behaviors but also chain mediators.

Conclusions

The results of the current study provide preliminary evidence that preventive interventions targeting anxiety and sense of security may be feasible for young women who develop disordered eating behaviors due to stress in their lives.

Tackling heterogeneity: Individual variability of emotion decoding deficits in severe alcohol use disorder

BACKGROUND

Severe alcohol use disorder (SAUD) is associated with social cognition deficits. Patients with SAUD are impaired for the recognition of emotional facial expressions, particularly at early stages of abstinence. These deficits damage interpersonal relations and increase relapse risk. However, uncertainties still abound on their variation across emotions and on the heterogeneity of emotional impairments across patients. We addressed these questions by exploring how the deficit varies according to emotions' type/intensity and patients' heterogeneity.

METHODS

Sixty-five recently detoxified patients with SAUD and 65 matched healthy controls performed the Facial Emotion Recognition Test, assessing the ability to identify six emotions (anger, contempt, disgust, fear, happiness, sadness) displayed by morphed faces with various intensities. Accuracy scores and detection thresholds were collected for each emotion. Beyond group comparisons, multiple single-case analyses determined the percentage of patients presenting decoding deficits for each emotion.

RESULTS

When current depression and anxiety symptoms were controlled for, patients did not present a general emotion decoding deficit, but were rather characterized by specific deficits for disgust/contempt in accuracy, and for disgust in detection threshold scores. Single-case analyses showed that only a third of patients presented a clinically significant emotional deficit.

CONCLUSIONS

Patients with SAUD only present emotional decoding deficits for specific interpersonal emotions (disgust/contempt) when subclinical psychopathological states are controlled for, and show no general emotional impairment. This goes against the proposal of a generalized social cognition deficit in this population. This group effect moreover masks a massive heterogeneity across patients, which has implications at experimental and clinical levels.

Depression in Mexican medical students: A path model analysis

Background

Depression is a mental health disorder present in medical students that foster cumulative disadvantages throughout life and that may compromise patient care. Yet, in Mexico there is a dearth of research concerning prediction models for depression in this population.

Methods

The aim of this cross-sectional study was to develop and test a path model analysis of depression in 103 freshmen Mexican medical students ages 18–23 years old selected non-randomly. Anxiety, emotion dysregulation, and coping skills were used as factors influencing depression. Mexican self-report scales were used as assessment measures.

Results

Main results showed that anxiety and emotion dysregulation had a significant direct influence on depression. Emotion dysregulation had a significant direct effect on coping skills and anxiety, while anxiety had a significant direct effect on problem drinking and alcohol problems. Fit indexes obtained indicate an excellent adjustment to data. R square indicates that 53.7% of the variance in depression can be explained by this model.

Limitations

The results are exploratory rather than confirmatory. The sample size was not large enough and the research focused on only Mexican freshmen medical students. Other factors associated to depression in medical students were not considered.

Conclusions

The current research provides unique findings in terms of a model of depression in Mexican medical students through which it is possible to design and implement interventions that decrease depression, thus positively affecting their well-being, their future careers as medical doctors and their abilities to serve the society adequately, especially in the context of Latin American cities.

Big Five, Self-Regulation, and Coping Strategies as Predictors of Achievement Emotions in Undergraduate Students

The study focused on the analysis of linear relations between personality, self-regulation, coping strategies and achievement emotions. The main objective was to establish a model of linear, empirical, associative to infer needs and proposals for intervening in emotional health in the different profiles of university students. A total of 642 undergraduate students participated in this research. Evidence of associative relations between personality factors, self-regulation and coping strategies was found. The neuroticism factor had a significant negative associative relationship with Self-Regulation both globally and in its factors; especially important was its negative relation to decision making, and coping strategies focused in emotion. The results of Structural Equation Model showed an acceptable model of relationships, in each emotional context. Results and practical implications are discussed.
