Investigating key latent factors influencing alcohol consumption among the tribal male adolescents in Dooars region, West Bengal

Background Alcohol consumption among tribal male adolescents in India is a significant social concern. Tribal adolescents are particularly vulnerable and tend to lean toward alcohol addiction. Therefore, it is crucial to introduce some necessary footsteps to reduce alcohol consumption. The primary objective of this study is to investigate the association of various latent factors with the alcohol-drinking behavior of tribal adolescents. Methods The study collected data from 600 tribal adolescents from the Dooars region, with 241 of them reported consuming alcohol. The study aimed to confirm the theoretical development of hypotheses regarding peer pressure, parental discord, stress, attitude toward alcohol, and food insecurity as exogenous latent factors influencing the alcohol-drinking behavior of tribal adolescents. In this context, the study adopted both measurement and structural models using Partial Least Squares-Structural Equation Modeling (PLS-SEM). Results The findings revealed a significant path relationship between alcohol drinking behavior and various exogenous factors like peer pressure (β = 0.214, p = .000), parental discord (β = 0.121, p = .009), stress (β = 0.170, p = .000), attitude toward alcohol (β = 0.110, p = .004), and food insecurity (β = 0.510, p = .000). This study developed a reflective measurement model, and the evaluation of reflective measurement models was conducted, assessing internal consistency, convergent validity, and discriminant validity, yielding satisfactory results. Conclusion To tackle alcohol issues among tribal adolescents in the Dooars region, effective strategies should be employed. These include educating in schools, highlighting tribal role models, aiding peers with alcohol dependence, providing life skills training, and addressing parental discord and food insecurity through awareness campaigns, workshops, and better infrastructure.

The influence of spirituality and religious participation on binge drinking: An investigation into subjective and structural mechanisms of desistance

PurposeResearch on the mechanisms of desistance from substance abuse have delineated between subjective and structural mechanisms. Similarly, research on religiosity has distinguished two separate domains, behavioral and attitudinal. The present study bridges these concepts and examines the impact of spirituality and religious participation on binge drinking behavior. MethodsThis paper uses a secondary data source for a sample of 1354 adolescents adjudicated for serious offenses followed over a 7-year period. The analysis employs multilevel mixed-effects logistic regression models to separate within, between, and person-context effects of subjective measure spirituality and structural measure religious participation on binge drinking. ResultsAnalyses reveal that the subjective factor, spirituality, has significant within effects on the likelihood to engage in binge drinking, while religious participation was not significant at either level. Furthermore, the interaction effect was found to be significant in that increased religious participation in combination with increased spirituality can increase the likelihood of abstinence from binge drinking. ConclusionsResults of this study hold implications for the desistance mechanism debate within the context of religiosity and substance use. Finding suggest the subjective factor of spirituality is more influential in the desistance process of binge drinking than the structural factor of religious participation.

Text Messages Conveying Parental Drinking Limits: A Potential Avenue for Preventing and Reducing Alcohol Use in College Students.

Although previous research has established that students who perceive that their parents have lower drinking limits on underage drinking consume less alcohol, optimal approaches for effectively communicating these limits are less understood. To address this gap in the literature, the present study examined the effects of hypothetical limit-focused text messages on estimated drinking behavior. Undergraduate college students (N = 253) completed an online survey in which they were instructed to imagine a scenario in which they were planning to go out at night to an event involving drinking. Participants were randomly assigned to a condition in which they would receive one of four hypothetical text messages from their mother and/or father containing a range of drinking limits. They were then asked to report how much alcohol they would realistically consume on this night if they were and were not obligated to check in with their parent at the end of the night. Hypothetical text messages from mothers and fathers containing lower drinking limits resulted in lower estimated alcohol consumption. A drinking limit of zero resulted in the least amount of expected alcohol consumption, but specifying 1-2 drinks as a limit might produce a similar effect if parents also required their student to check in at the end of the night. Findings from this study provide initial support for future studies to investigate the effects of limit-setting text messages sent from parents on college student drinking as well as the effects of text messages sent from parents requiring that students check in.

Is the 21st birthday a turning point for alcohol and cannabis use? A monthly study of young adults.

An important life-course event with respect to alcohol and cannabis use is turning 21 years of age, which may be associated with increases in use of these substances due to celebrations during the month and easier access to them on and following this birthday. We examined the trajectories of alcohol and cannabis use behaviors in the months leading up to, during, and following the 21st birthday month. We also examined whether the use trajectories vary by college status and baseline levels of use. We used data from 203 young adults recruited from the Greater Seattle region who turned 21 during the course of the study. Surveys were administered each month for 24 consecutive months. Measures included the typical number of drinks per week for the past month, the frequency of heavy episodic drinking, the number of cannabis use days, and any simultaneous alcohol and cannabis use. Multilevel spline models were run that estimated linear slopes over time at four intervals: (1) up to 1 month before the 21st birthday month; (2) from 1 month before to the month of the 21st birthday; (3) from the 21st birthday month to 1 month following; and (4) from 1 month following the 21st birthday month through all following months. Alcohol use, generally, and simultaneous alcohol and cannabis use showed sharp increases from the month before the 21st birthday month to the 21st birthday month and decreases following the 21st birthday month. For cannabis use, there were significant increases in the months leading up to the 21st birthday and no other significant changes during other time intervals. Patterns differed by baseline substance use and college status. Findings from the current study have implications for the timing and personalization of prevention and intervention efforts. Event-specific 21st birthday interventions may benefit from incorporating content targeting specific hazardous drinking behaviors in the month prior to the 21st birthday.

Factor structure, group invariance, and concurrent validity of scores from the college eating and drinking behavior scale among U.S. college students

Food and alcohol disturbance (FAD) refers to the intersection of alcohol- and eating-related motives and behaviors, such as restricting food intake before or during alcohol use to offset caloric intake or to enhance intoxication. Valid assessment is critical for advancing research on FAD. We tested the factor structure, group invariance, and concurrent validity of the College Eating and Drinking Behavior Scale (CEDBS) in a large college student sample (n = 2610; Mage = 20.95, SD = 4.65; 71.8% female; 77% White; 86% non-Hispanic). Participants completed measures assessing antecedents of alcohol use (i.e., protective behavioral strategies and drinking motives), negative alcohol-related consequences, alcohol use severity, and risk for eating disorder. The 3-factor model of the 21-item CEDBS provided an adequate fit to the data (e.g., CFI = 0.916). These factors include Alternative Methods (4 items; “Use laxative prior to drinking alcohol”), Offset Calories (7 items; “Restrict calories prior to drinking to help maintain your figure”), and Quicker Intoxication (10 items; “Not eating before drinking alcohol because it gives you the best buzz”). The CEDBS was scalar invariant across subgroups of participants based on age, sex, race/ethnicity, socioeconomic status, sexual orientation, and political orientation. Quicker Intoxication was most strongly related to risk factors and negative consequences for alcohol (r = 0.204–0.379, all ps < 0.01), and Offset Calories was most strongly related to risk for eating disorders (r = 0.349, p < .01). These findings further support the CEDBS to assess FAD among college students.

The Role of Personalization in Virtual Reality Exposure Therapy During the Treatment of Alcohol Use Disorder

IntroductionIn Cue-Exposure-Therapy (CET), clients are exposed to triggers through objects, people and environments that arouse craving (Sinha et al. Neuropsychopharmacol. 2009;34 1198–1208). Virtual Reality Exposure therapy (VRET) is used to experience these triggers in a realistic, safe, and personalized way. VR has been used successfully in the treatment of psychiatric disorders. It has not yet been developed and sufficiently tested as an adjuvant in the clinical post-detoxification phase of treatment of alcohol use disorders (AUD) (e.g. Bordnick et al. Addict.Behav 2008;33 743-756; Hone-Blanchet et al. Front.Hum.Neurosci. 2014; 8(844) 1-15). Additionally, these treatment methods have been tested for effect, but not for effectiveness around different VR technologies (Ghita &amp; Gutierrez-Maldonado. Addict.Behav 2018; 81 1-11; ). This study focuses on VRET-Recovry to examine to what extent VR worlds could be personalized in an effective manner to help treat AUD as well as clarifying on the ways in which the VR worlds could be optimized to achieve its goal.ObjectivesThe primary objectives of this study are to assess the necessity of personalization in VR environments for AUD treatment, identify the critical elements for personalization, and examine their impact on craving in AUD patients.MethodsThe study included 10 AUD patients diagnosed according to DSM-V criteria, aged between 18 and 65, who were in the final week of clinical detoxification at a large addiction clinic in The Netherlands. A controlled experiment was conducted using the Recovry 1.0 VR system on Samsung Gear VR and Samsung Galaxy S9. The experiment involved exposure to various VR scenes (CG and 360o), including a neutral setting, a bar scene, and a home situation, with the duration and sequence controlled by a therapist. Data collection consisted of pre- and post-exposure questionnaires, heart rate and blood pressure measurements, and interviews.ResultsCraving was remarkably low in the VR bar scene, primarily due to its unsociable context, limited alcohol visibility, and absence of peer pressure. Technical limitations, such as suboptimal resolution, also affected the feeling of presence. Positive results were shown that craving was predominantly stimulated in the apartment scene, driven by the presence of alcohol-related visual cues and social elements, resembling relaxed drinking with others.ConclusionsThis study underscores that some degree of personalization is needed on all craving dimensions with clear preference was given to CG or 360°. The environments were dependent on the personal history and associations they represent to different levels of alcohol visibility (messy or clean), and types of drink (based on past drinking behavior), and different emotional contexts are needed (positive and negative).Disclosure of InterestNone Declared

Environmental enrichment during yard weaning alters the performance of calves in an attention bias and a novel object recognition test

The weaning of beef calves in yards places multiple stressors on the animals, and environmental enrichment may help mitigate some of these stressors and improve animal welfare. This trial assessed the impacts of enrichment provision to beef calves during yard weaning using measures of biological functioning, behaviour, and affective state. Overall, calves utilised the brush more than the other provided enrichments, which were a hanging rope and a ball. Enrichment influenced the behaviours of calves during both an attention bias test, with enriched calves exhibiting behaviours associated with greater anxiety, and a novel object recognition test, with enriched calves spending less time interacting with objects. In their home pens, enriched calves performed more drinking and grooming behaviours. However, no significant differences were seen between treatments for body weight, faecal cortisol metabolites, and internal body temperature. Enrichment also did not influence any longer-term measurements of body weight, flight speed, or crush score. The study design was impacted by mud, requiring the regrouping of the animals. Thus, some results should be interpreted with caution. Overall, this study demonstrates that further work is required into the assessment of affective states for these animals as it could not be confirmed whether the results seen indicate that calf welfare was improved or impaired through enrichment provision.

Alcohol drinking, DNA methylation and psychiatric disorders: A multi-omics Mendelian randomization study to investigate causal pathways.

Whether alcohol-related DNA methylation has a causal effect on psychiatric disorders has not been investigated. Furthermore, a comprehensive investigation into the causal relationship and underlying mechanisms linking alcohol consumption and psychiatric disorders has been lacking. This study aimed to evaluate the causal effect of general alcohol intake and pathological drinking behaviors on psychiatric disorders, alcohol-associated DNA methylation on gene expression and psychiatric disorders, and gene expression on psychiatric disorders. Two-sample design Mendelian randomization (MR) analysis. Various sensitivity and validation analyses, including colocalization analysis, were conducted to test the robustness of the results. Genome-wide association study (GWAS) data mainly from GWAS and Sequencing Consortium of Alcohol and Nicotine use (GSCAN), Genetics of DNA Methylation Consortium (GoDMC) and Psychiatric Genomics Consortium (PGC) with European ancestry. The GWAS summary data on general alcohol intake (drinks per week, n = 941 280), pathological drinking behaviors (including alcohol use disorder [AUD, n = 313 959] and problematic alcohol use [PAU, n = 435 563]) and psychiatric disorders (including schizophrenia, major depressive disorder and bipolar disorder, n = 51 710-500 199) were included. Alcohol-related DNA methylation CpG sites (n = 9643) and mQTL data from blood (n = 27 750) and brain (n = 1160), BrainMeta v2 and GTEx V8 eQTL summary data (n = 73-2865) were also included. Genetic variants were selected as instrumental variables for exposures, including drinks per week, AUD, PAU, alcohol-related DNA methylation CpG sites (mQTL) and genes selected (eQTL). Pathological drinking behaviors were associated with an increased risk of psychiatric disorders after removing outliers or controlling for alcohol consumption. MR analysis identified 10 alcohol-related CpG sites with colocalization evidence that were causally associated with psychiatric disorders (P = 1.65 × 10-4-7.52 × 10-22). Furthermore, the expression of genes (RERE, PTK6, GATAD2B, COG8, PDF and GAS5) mapped to these CpG sites in the brain, led by the cortex, were significantly associated with psychiatric disorders (P = 1.19 × 10-2-3.51 × 10-7). Pathological drinking behavior and alcohol-related DNA methylation appear to have a causal effect on psychiatric disorders. The expression of genes regulated by the alcohol-related DNA methylation sites may underpin this association.

Event-Level Drinking Intentions, Social Drinking Contexts, and Motives Affect Alcohol Consumption Among Same-Sex Female Couples.

Young sexual minority women (SMW; e.g., lesbian, bisexual women) are at increased risk for heavy drinking, although SMW in relationships may be at less risk than those who are single. The current study examined how SMW partners influence drinking in the moment, if their own intentions predict drinking beyond partner influence and if this association is moderated by partner influence, and if their own drinking motives moderate partner influence. Young adult same-sex female couples (N = 162 couples) were recruited to participate in a 14-day daily diary study where they reported each morning their drinking intentions, motives, and behavior as well as whether their partner was present during drinking occasions. Findings from multilevel structural equation models revealed that own intentions and select partner influences (i.e., intentions, drinking) were uniquely linked to a greater quantity of drinking at the within-subject level. Significant interactions between own intentions and partner intentions, and between partner intentions and select drinking motives (social and enhancement), on same-day alcohol use were found at the within-subject level. Findings suggest that partner influences have a strong effect on drinking at the daily level and can be strengthened or weakened when drinking for specific reasons. These findings expand on prior daily diary research on the effects of drinking motives by examining how these processes unfold in same-sex female couples and their intersection with partner intentions.

The role of parental maladaptive emotion socialization in the risk process for negative urgency and drinking behavior in adolescence.

Negative urgency (the tendency to act rashly when experiencing negative emotions) is a robust risk factor for a number of problem behaviors, including early adolescent drinking. Little is known about the factors that precede the development of negative urgency, and hence the full etiology of this component of risk. The current study aimed to investigate the possibility that facets of childhood maladaptive emotion socialization (the tendency for children's expressions of emotions to be met with punishment, minimized, or invoke a reaction of distress from their parents/caretakers) increases risk for the development of negative urgency and drinking behavior. Self-report measures of negative urgency, subfacets of maladaptive emotion socialization, and drinking behavior were collected during the 2021-2022 academic year from a sample of 428 high school students (mean age = 14.7, SD = 0.09, 44% female), assessed twice over the course of a semester, reflecting a 4-month longitudinal window. Distress emotion socialization predicted increases in negative urgency, minimizing predicted decreases in negative urgency, and punitive did not provide significant prediction. Additionally, results found that higher levels of both negative urgency and distress emotion socialization increased adolescents'likelihood of having tried alcohol. These processes were invariant across race and gender. The present study may inform the future creation of prevention and intervention efforts aimed at reducing maladaptive emotion socialization and increasing adaptive emotion socialization. Successful reductions in negative urgency as a consequence of increased adaptive emotion socialization may then lead to decreases in adolescent drinking and other impulsigenic behaviors.

Drinking behavior patterns may be associated with persistent depressive symptoms after alcohol abstinence in alcohol use disorder.

This study examined the association between drinking behavior patterns and depressive symptoms after alcohol abstinence in patients with alcohol use disorder (AUD). We recruited 102 AUD inpatients with baseline depressive symptoms, indicated by scores ≥6 on the Quick Inventory of Depressive Symptomatology Self-Report Japanese Version (QIDS-SR-J) pre-detoxification. Post-4-week abstinence, remission was defined as QIDS-SR-J scores <6. Patients were classified into remitted (n = 51) and persistent (n = 51) groups. Comparative analyses were conducted using patient profiles and the Drinking Behavior Pattern 20-item Questionnaire (DBP-20). Logistic regression identified factors related to post-abstinence persistent depression. Receiver operating characteristic curve analysis determined DBP-20 cutoff scores differentiating between persistent and remitted depression. The persistent group exhibited higher scores in the DBP-20 "coping with negative affect" subscale. Logistic regression showed low education, unemployment, and using alcohol for coping as significant factors for persistent depression. Conversely, an automatic drinking pattern indicated natural remission post-abstinence. A subscale score of ≥8 in alcohol use for coping, especially among unemployed patients, predicted persistent depression (sensitivity 86.8%, positive predictive value 73.3%). Unemployed patients with AUD using alcohol to cope with negative affect may experience residual depression even after detoxification. In contrast, patients with AUD with predominantly automatic drinking behavior may exhibit natural remission post-abstinence.

Monitoring individual drinking behaviour and the social hierarchy in dairy cows using electronic drinkers

Sufficient access to clean drinking water is essential for the production and welfare of dairy cows. However, dairy farms vary greatly in how they provide water to cows. Electronic drinkers are now available to monitor cows’ water intake on individual level and can be used to better define their water need. The objective of this study was to validate the detection of agonistic replacements when competing for water access with a new electronic drinker and to explore the ability of using these interactions to identify the social hierarchy within a group of cows. A group of 22 Holstein mid-lactating cows were housed in a free-stall barn equipped with 6 electronic drinkers, 22 individual feeders and 7 cameras. For 9 days over the 18 days of the trial, agonistic interactions were identified via video. We used an algorithm relying on visit start times of subsequent cows at the electronic drinkers to automatically detect agonistic replacements. We determined 4 social hierarchies using the normalized David's score (NormDS) based on 1) agonistic interactions video observed in areas outside the drinkers, 2) agonistic interactions video observed at the drinkers, 3) replacements at the drinkers obtained from video, and 4) replacements at the drinkers detected by the algorithm. We found a weak correlation between the hierarchy recorded outside the drinkers and the one based on agonistic interactions at the drinkers. The hierarchy based on agonistic interactions at the drinkers was strongly correlated with the one relying on video-based replacements but showed a weaker association with the hierarchy relying on replacements detected by the algorithm. To explore the influence of dominance on drinker use, we defined dominant (n = 6), mid-dominant (n = 6), mid-subordinate (n = 4) and subordinate (n = 6) cows according to NormDS quartiles in the video-based replacement hierarchy. Subordinate cows drank less than the other social groups at the peak consumption of the whole group at 1800 h but drank more than the most dominant cows 2 hours later. Subordinate cows preferentially used the most isolated drinker of the barn, furthest from the feeding area, and they drank less from drinkers in higher density areas. Detecting replacements at the drinker can be useful in studies aimed to analyze the effect of social groups on individual drinking behaviour. However, we suggest that for the automatic detection of replacements at the drinker, technology that allows for the recording of non-drinking visits is necessary.

Establishing Motivational Profiles to Drink among College Students: Converging Patterns Using Multiple Theories of Alcohol use.

Objective: While college student drinking has been studied utilizing many different theories and approaches, it is unclear how these theories may overlap in their explanation of problematic drinking. Rather than relying on one theory, examining overlap between multiple theories of alcohol use may lead to a better understanding of the motivational process underlying drinking behavior. The current study proposes that the Ambivalence Model of Craving, Behavioral Economics, and Alcohol Outcome Expectancy Theory account for the same underlying anticipatory process and sought to demonstrate this by establishing motivational profiles utilizing constructs within each theory. Methods: A total of 318 college student drinkers completed a series of surveys assessing their drinking behavior and the measures pertaining to each theory (i.e., Approach and Avoidance of Alcohol Questionnaire, Alcohol Purchase Task, Alcohol Expectancy Questionnaire). A latent profile analysis was used to establish profiles of motivational tendencies. Results: Results from the latent profile analysis indicated four profiles emerged, three of which were consistent with our hypotheses: approach, avoidance, and indifferent. The fourth motivational profile appeared to represent drinkers with an emerging approach tendency but relatively newer to drinking. The lack of ambivalent profile suggests that avoidant tendencies may develop later in response to an accumulation of experience with drinking. Lastly, these profiles demonstrated expected relationships with drinking behavior. Conclusion: This study is unique in its attempt to highlight similarities between theories. Results provide a useful integration of theories to allow for a more generalized understanding of motivational tendencies that develop in response to drinking experiences.

Correlates of Sexual Victimization Among Community College Women.

The current study documents the correlates associated with the severity of sexual victimization among women enrolled in a 2-year community college. Comparisons between women with a history of severe sexual victimization (i.e., rape and attempted rape), moderate sexual victimization (i.e., unwanted contact and sexual coercion), and no history of sexual victimization revealed that women with a history of severe sexual victimization endorsed more drinks per week, increased problem drinking behavior, and more use of drug before sex and higher levels of self-protective dating behaviors compared with women with no history of sexual victimization. These findings suggest that programs should target the intersection of alcohol and drug use as correlates of sexual victimization among community college women.

Dynamic Associations Between Anxiety Symptoms and Drinking Behavior From Early Adolescence to Young Adulthood

PurposeResearch is inconclusive with respect to the possible risk-increasing effect of anxiety symptoms on heavy drinking behavior among adolescents and young adults. Adult role transitions and changes in the social context from early adolescence into young adulthood may impact the association between anxiety symptoms and alcohol use. MethodsThe TRacking Adolescents’ Individual Lives Survey, including 2,229 individuals at baseline, was used to evaluate the bi-directional and longitudinal associations between anxiety symptoms and alcohol use, using data at 14, 16, 19, 22, and 25 years of age. ResultsCross-lagged models revealed a relatively stable negative association at 14, 16, and 19 years, showing that relatively higher anxiety symptoms were associated with relatively lower drinking levels three years later. This effect was absent in young adulthood. There was no evidence for significant associations between alcohol use and subsequent anxiety symptoms, with the exception of alcohol use at age 19, which predicted relatively lower levels of anxiety symptoms at age 22. DiscussionOverall, the results indicated that anxiety symptoms may withhold adolescents from (heavy) drinking, although this protective effect disappeared in young adulthood. Transitions in social contexts as well as autonomy and adult responsibilities could underlie the changing association between alcohol use and anxiety symptoms throughout adolescence and young adulthood.

Acute and chronic alcohol modulation of extended amygdala calcium dynamics

The central amygdala (CeA) and bed nucleus of the stria terminalis (BNST) are reciprocally connected nodes of the extended amygdala thought to play an important role in alcohol consumption. Studies of immediate-early genes indicate that BNST and CeA are acutely activated following alcohol drinking and may signal alcohol reward in nondependent drinkers, while stress signaling in the extended amygdala following chronic alcohol exposure drives increased drinking via negative reinforcement. However, the temporal dynamics of neuronal activation in these regions during drinking behavior are poorly understood. In this study, we used fiber photometry and the genetically encoded calcium sensor GCaMP6s to assess acute changes in neuronal activity during alcohol consumption in BNST and CeA before and after a chronic drinking paradigm. Activity was examined in the pan-neuronal population and separately in dynorphinergic neurons. BNST and CeA showed increased pan-neuronal activity during acute consumption of alcohol and other fluid tastants of positive and negative valence, as well as highly palatable chow. Responses were greatest during initial consummatory bouts and decreased in amplitude with repeated consumption of the same tastant, suggesting modulation by stimulus novelty. Dynorphin neurons showed similar consumption-associated calcium increases in both regions. Following three weeks of continuous alcohol access (CA), calcium increases in dynorphin neurons during drinking were maintained, but pan-neuronal activity and BNST-CeA coherence were altered in a sex-specific manner. These results indicate that BNST and CeA, and dynorphin neurons specifically, are engaged during drinking behavior, and activity dynamics are influenced by stimulus novelty and chronic alcohol.

Longitudinal effects of disaster-related experiences on problem drinking among Fukushima nuclear plant workers.

In the Fukushima nuclear power plant disaster of March 11, 2011, plant workers were exposed to various traumatic events and reported a subsequent increase in alcohol use. To determine the relationship between disaster-related experiences and problem drinking, we conducted a three-year follow-up study. Problem drinking among the nuclear plant workers was assessed annually from 2012-2014 using a modified version of the CAGE questionnaire that asked about current, rather than lifetime, drinking. A total of 1378 workers provided at least one CAGE response, and 2875 observations were used in the present analysis. Mixed-effects logistic regression models were used to analyze the relationship between disaster-related experiences and problem drinking over time. The prevalence of problem drinking (CAGE score ≥2) increased over time. At the baseline assessment in 2012, a year after the disaster, plant workers who had experienced life-threatening danger and discrimination had significantly more symptoms of problem drinking, which persisted over the following 2 years. Although at baseline, plant workers who had experienced major property loss or the death of a colleague showed no significant differences in problem drinking symptoms from those without such experiences, over the next 2 years their problem drinking increased significantly. Individuals who experienced life-threatening danger and discrimination during the Fukushima nuclear power plant disaster reported an increase in problem drinking. Although major property loss and the death of a colleague did not elevate problem drinking prevalence at baseline, it did so over the next 2 years. Different adverse effects of a natural disaster appear to differentially increase drinking behavior over time.

A smartphone application to reduce problematic drinking: a feasibility trial

BackgroundProblematic drinking is common among college students and associated with various somatic and mental health problems. Given significant evidence for the efficacy of smartphone-based interventions and the frequent use of smartphones among college students, it can be assumed that such interventions have great potential to facilitate access to evidence-based interventions for students suffering from problematic drinking. Thus, we developed a brief intervention that combined a counseling session with an app that utilizes approach-avoidance modification training to reduce alcohol consumption.MethodsTo test the feasibility and explore the potential efficacy of the intervention, we conducted a before-after single-arm study with N = 11 participants reportedly engaging in problematic drinking, who were instructed to practice with the app for 14 days. Feasibility was assessed with the System Usability Scale (SUS). Outcomes included the reduction of self-reported problematic drinking behavior, dysfunctional attitudes about alcohol, and craving, as well as implicit associations between alcohol and self during the training period. Additionally, self-reported problematic drinking behavior was assessed at a 4-week follow-up.ResultsOn average, participants rated app usability on the SUS (possible range: 0 to 100) with M = 84.32 (SD = 6.53). With regard to efficacy, participants reported a significant reduction of problematic drinking behavior (dpre vs. post = 0.91) which was sustained at follow-up (dfollow-up vs. baseline = 1.07). Additionally, participants reported a significant reduction of dysfunctional attitudes about alcohol (dpre vs. post = 1.48). Results revealed no significant changes in craving nor in implicit associations regarding alcohol.ConclusionsFindings from this feasibility study provide preliminary evidence that smartphone-based interventions might help reduce problematic drinking in college students. Further research needs to replicate these findings with larger samples in randomized controlled trials.Trial registrationDRKS00014675 (retrospectively registered).

The prevalence of alcohol references in music and their effect on people's drinking behavior: A systematic review and meta-analysis.

Understanding the prevalence of alcohol references in music and their impact on alcohol drinking behavior is important given the increased accessibility to daily music listening with the proliferation of smart devices. In this review, we estimate the pooled prevalence of alcohol references in music and its association with drinking behavior. Systematic searches were conducted across four major databases (MEDLINE, PsycINFO, EMBASE, and CINHAL). Articles were selected following duplicate checking, title and abstract screening, and full-text review. Studies reporting the prevalence of alcohol-referencing music and/or investigating its association with drinking behavior were included. Pooled prevalence with 95% confidence intervals (CIs) were computed using a random effects model. Of 1007 articles identified, 26 met inclusion criteria and 23 studies comprising 12,224 songs were eligible for meta-analysis. The overall pooled prevalence of alcohol references in music (including lyrics and videos) was 24.0% (95% CI: 19.0%-29.0%). The pooled prevalence was 22.0% (95% CI: 16.0%-29.0%) for only lyrics, 25.0% (95% CI: 18.0%-33.0%) for only the visual elements of music videos, and 29.0% (95% CI: 21.0%-38.0%) for both the lyrical content and the visual components. Only three studies assessed the relationship between listening to music with alcohol references and drinking behavior, and all three reported a positive association. Whereas almost a quarter of all songs included references to alcohol, public health preventive measures are needed to reduce alcohol exposure from music. Future research is needed to understand fully the effect of music with alcohol references on drinking behavior.
