RESUMEN

INTRODUCTION: Children's early experiences with alcohol inform the development of alcohol-related beliefs which are known to predict alcohol consumption during the critical stage of adolescence. Yet, there has been considerably less research into these alcohol-related cognitions in low- and middle-income countries (LMIC) and existing measures of these beliefs are highly reflective of Western contexts, which may not be fully appropriate for use in LMICs. The aim is to ascertain the construct validity of the Alcohol Expectancies Questionnaire (AEQ) in a non-Western sample. METHODS: A cross-sectional diagnostic accuracy study involving 500 adolescents aged 10 to 18 years randomly selected from the database of the Navrongo Health and Demographic Surveillance System. Participants were administered the locally back translated version of the 34-item AEQ. Confirmatory factor analysis using the lavaan package in R was conducted to generate indices for the factor structure of the AEQ. RESULTS: Confirmatory factor analyses showed that while groupings of positive and negative expectancies were similar to those observed when expectancies have been assessed previously in Western studies, these formed a single 'alcohol expectancy' factor. Questions relating to positive tension reduction and negative physical expectancies showed inconsistent responses in this study. DISCUSSION AND CONCLUSIONS: Commonly used tools for the assessment of alcohol expectancies may not be suitable for use in Ghana, possibly owing to their development and validation in Western contexts. These findings have implications for the assessment of alcohol-related beliefs in LMIC settings and begin to map out a research agenda to develop more contextually and culturally attune alcohol assessments.

RESUMEN

Research examining how crowd emotions impact observers usually requires participants to engage in an atypical mental process whereby (static) arrays of individuals are cognitively integrated to represent a crowd. The present work sought to extend our understanding of how crowd emotions may spread to individuals by assessing self-reported emotions, attention and muscle movement in response to emotions of dynamic, virtually modeled crowd stimuli. Self-reported emotions and attention from thirty-six participants were assessed when foreground and background crowd characters exhibited homogeneous (Study 1) or heterogeneous (Study 2) positive, neutral, or negative emotions. Results suggested that affective responses in observers are shaped by crowd emotions even in the absence of direct attention. Thirty-four participants supplied self-report and facial electromyography responses to the same homogeneous (Study 3) or heterogeneous (Study 4) crowd stimuli. Results indicated that positive crowd emotions appeared to exert greater attentional pull and objective responses, while negative crowd emotions also elicited affective responses. Study 5 (n = 67) introduced a control condition (stimuli containing an individual person) to examine if responses are unique to crowds and found that emotional contagion from crowds was more intense than from individuals. These studies present methodological advances in the study of crowd emotional contagion and have implications for our broader understanding of how people process, attend, and affectively respond to crowds. Advancing theory by suggesting that emotional contagion from crowds is distinct from that elicited by individuals, findings may have applications for refining crowd management approaches.

RESUMEN

OBJECTIVES: Problematic substance use is one of the most stigmatized health conditions leading research to examine how the labels and models used to describe it influence public stigma. Two recent studies examine whether beliefs in a disease model of addiction influence public stigma but result in equivocal findings-in line with the mixed-blessings model, Kelly et al. (2021) found that while the label "chronically relapsing brain disease" reduced blame attribution, it decreased prognostic optimism and increased perceived danger and need for continued care; however, Rundle et al. (2021) conclude absence of evidence. This study isolates the different factors used in these two studies to assess whether health condition (drug use vs. health concern), etiological label (brain disease vs. problem), and attributional judgment (low vs. high treatment stability) influence public stigma toward problematic substance use. METHOD: Overall, 1,613 participants were assigned randomly to one of the eight vignette conditions that manipulated these factors. They completed self-report measures of discrete and general public stigma and an indirect measure of discrimination. RESULTS: Greater social distance, danger, and public stigma but lower blame were ascribed to drug use relative to a health concern. Greater (genetic) blame was reported when drug use was labeled as a "chronically relapsing brain disease" relative to a "problem." Findings for attributional judgment were either inconclusive or statistically equivalent. DISCUSSION: The labels used to describe problematic substance use appear to impact discrete elements of stigma. We suggest that addiction is a functional attribution, which may explain the mixed literature on the impact of etiological labels on stigma to date.

RESUMEN

Background Previous investigations suggest that the COVID-19 pandemic effects on alcohol consumption were heterogenous and may vary as a function of structural and psychological factors. Research examining mediating or moderating factors implicated in pandemic-occasioned changes in drinking have also tended to use single-study cross-sectional designs and convenience samples. AIMS: First, to explore structural (changed employment or unemployment) and psychological (subjective mental health and drinking motives) correlates of consumption reported during the COVID-19 pandemic using a UK nationally representative (quota sampled) dataset. Second, to determine whether population-level differences in drinking during the COVID-19 pandemic (versus pre-pandemic levels) could be attributable to drinking motives. METHOD: Data collected from samples of UK adults before and during the pandemic were obtained and analysed: Step1 carried out structural equation modelling (SEM) to explore data gathered during a period of social restrictions after the UK's first COVID-19-related lockdown (27 August-15 September, 2020; n = 3,798). It assessed whether drinking motives (enhancement, social, conformity, coping), employment and the perceived impact of the pandemic on subjective mental health may explain between-person differences in self-reported alcohol consumption. Step 2 multigroup SEM evaluated data gathered pre-pandemic (2018; n = 7,902) in concert with the pandemic data from step 1, to test the theory that population-level differences in alcohol consumption are attributable to variances in drinking motives. RESULTS: Analyses of the 2020 dataset detected both direct and indirect effects of subjective mental health, drinking motives, and employment matters (e.g., having been furloughed) on alcohol use. Findings from a multigroup SEM were consistent with the theory that drinking motives explain not only individual differences in alcohol use at both time points, but also population-level increases in use during the pandemic. CONCLUSION: This work highlights socioeconomic and employment considerations when seeking to understand COVID-19-related drinking. It also indicates that drinking motives may be particularly important in explaining the apparent trend of heightened drinking during the pandemic. Limitations related to causal inference are discussed.

RESUMEN

BACKGROUND: Theory of mind (ToM) - the ability to understand others' beliefs, mental states, and knowledge - is an important part of successful social interaction. There is a growing (albeit mixed) evidence base suggesting that individuals with substance use disorder or who are intoxicated (relative to sober controls) perform worse on a number of ToM tasks. The aim of this study was to explore the hitherto little explored notion that ToM-related capabilities such as the ability to see the world from another person's perspective (termed Visual Perspective Taking; VPT), may be impacted by alcohol-related stimuli. METHOD: In this pre-registered study, 108 participants (M age = 25.75, SD age = 5.67) completed a revised version of the director task where they followed the instructions of an avatar to move both alcohol beverages and soft drinks that were mutually visible (target objects) while avoiding those only visible to the participant (distractor items). RESULTS: Contrary to predictions, accuracy was lower when the target drink was alcohol and the distractor was a soft drink, although higher AUDIT scores were associated with significantly lower accuracy when alcohol drinks were the distractor items. CONCLUSIONS: There may be some contexts when being able to see alcohol beverages makes it harder to take another person's perspective. It also appears that poorer VPT and perhaps ToM capacity may be evident in individuals who consume more alcohol. Future research is warranted to examine how alcohol beverages, alcohol consumption behaviours, and intoxication interact to impact VPT capacity.

RESUMEN

This study contrasts young people's predrinking in two European cultural contexts: Spain and the UK. Whilst UK predrinking typically occurs amongst small groups of individuals who already know one another, the distinctive Spanish context of the Botellón details a far larger gathering in which participants may be less likely to know each other. As such, predrinking motives which drive consumption and risk-taking may be expected to vary between these cultures. An online questionnaire (N = 397; UK = 167, Spain = 230) was used to examine a variety of drinking behaviours and associated beliefs/motivations including predrinking motivations, drinking behaviour, and risk taking. Path analysis was used to analyse both direct and indirect relationships between the measures with the aim of predicting problem alcohol consumption with the most parsimonious model. Varying (in)direct paths were observed between predrinking motives and alcohol consumption between the cultures. Most notably and pointing towards inconsistency in the drivers of young adults' drinking, fun predrinking motives featured prominently among Spanish respondents and predicted their reported consumption (not so in the UK), while conviviality was a more prevalent predrinking motive in the UK sample and associated with alcohol consumption (not the case in Spain). Further, (personal) risky behaviour and risk-taking predicted consumption in both samples, suggesting the importance of group norms and behaviours in predrinking activity, irrespective of alcohol consumption. These findings highlight the potential importance of the environment in which young people predrink. Given their importance in shaping alcohol consumption and risk taking in young people, cultural differences in predrinking contexts and motives warrant further investigation.

RESUMEN

Coronavirus disease (COVID-19)-related lockdown provided an opportunity to examine the relationship between affect and alcohol consumption in a historically unique context. To shed light on mixed findings regarding the interplay between affective states and alcohol consumption, the present study examined how affective states and affect fluctuations impact drinking during confinement of people to their homes. It also examined the extent to which the social context moderated the affect-consumption relationship. Having preregistered study protocols, methods, and hypotheses, 87 U.K. participants (34% male, Mage = 29.33) used their smartphones to respond to thrice daily prompts, recording their affective states, alcohol consumption, and social context over 1 week. Multilevel modeling suggested that being with someone (vs. alone) was associated with increased alcohol consumption. Increased drinking on the previous day was associated with increased next day negative affect, and the number of household occupants was associated with decreased negative affect. Preconsumption affect was not associated with subsequent drinking. These findings point to a complex relationship between alcohol consumption, social context, and negative affect. The opportunity to interact with others during lockdown was generally associated with decreased negative affect in the moment. However, the presence of others was associated with increased consumption which, in turn, predicted elevated next-day negative affect. (PsycInfo Database Record (c) 2023 APA, all rights reserved).

RESUMEN

Alcohol expectancies are well-established determinants of alcohol consumption. Traditionally, expectancies were assessed using self-report questionnaires. However, researchers have increasingly begun to explore the use of pictographic assessments, for example, the revised Alcohol Expectancy Task [rAET]. The current research aimed to examine the factor structure of the task in relation to the hypothesised expectancy dimensions, participants' endorsement of these dimensions, and whether rAET scores are associated with drinking patterns. The rAET presents participants with several illustrated scenarios in which people are displaying emotions, following the Circumplex Model of Affect. For each scenario, participants select which type of drink the person presented in the illustration was most likely to have drunk. The rAET was administered online to a convenience sample (n = 1,192, female: 50.7%, Mage = 36.8, SD = 13.7). The confirmatory factor analysis demonstrated adequate fit of the hypothesised four-factor model. Mean comparisons demonstrated that positive expectancies were more pronounced than negative expectancies, and a distinction between arousal and sedation expectancies was found. Results of a structural equation model found that positive sedation and positive arousal were related to high drinking frequency. There were no links between usual quantity of alcohol use or binge drinking. It appears that the rAET can be successfully used to assess alcohol expectancies in terms of the emotions that are expected to occur from alcohol consumption. Future research is needed to establish the tool's assessment properties in different settings, and its utility in predicting alcohol consumption in different age groups, particularly children and young adolescents.

RESUMEN

OBJECTIVE: Public health policies aim to reduce alcohol consumption and related harms by controlling the cost and availability of alcohol, yet industry actors seek to position branded beverages appealingly vis-à-vis other products. To inform the development of regulatory strategies, it is important to understand how alcohol branding interacts with seductive pricing strategies to influence purchasing decisions. Toward this aim, the current study examines how the "decoy effect" may operate to modify purchasing decisions for branded alcoholic beverages. METHOD: Social drinkers (n = 98, 66.6% female; M AUDIT = 5.00, SD = 4.42) completed an online Decoy Assessment, choosing from a range of (non)branded, (non)alcoholic beverage offers based on price and quantity. These initial purchasing decisions were then re-assessed when a decoy product--offering a quantity in between the two original offers but at a significantly higher price--was introduced into the choice array. RESULTS: The decoy modified initial purchasing decisions for alcoholic compared with nonalcoholic beverages, and this effect was exacerbated by alcohol branding. Increases in self-reported alcohol consumption were associated with a greater change from choices for branded alcoholic beverages. CONCLUSIONS: When faced with a choice conflict, individuals who consume alcohol may be nudged into selecting more expensive branded alcoholic beverages. These findings may inform the development of alcohol control policies relating to branding and relative pricing/product placement.

RESUMEN

Background: Recent meta-analytical findings indicate that affect regulation plays an important role in alcohol craving, consumption volume, and substance use. However, in view of mixed findings, the affect and drinking likelihood literature remains in need of clarification and consolidation.Objectives: This systematic review with meta-analyses interrogated the results from peer-reviewed studies among non-clinical populations that examined the relationship between daily affective states and intraday likelihood of alcohol consumption.Method: A PRISMA guided search of PsychINFO, PsycARTICLES, Science Direct, Wiley Online Library, PubMed, SCOPUS, and JSTOR databases was conducted. Multilevel meta-analyses yielded 11 eligible negative affect studies (2751 participants, 23 effect sizes) and nine studies on positive affect (2244 participants, 14 effect sizes).Results: The pooled associations between intra-day affect and alcohol consumption likelihood revealed no significant association between negative affective state and drinking likelihood (OR = .90, 95% CI [.73, 1.12]) and that positive affect was associated with increased drinking likelihood (OR = 1.17, 95% CI [1.09, 1.27]). Egger's test, P-curve, fail-safe N, and selection models analyses suggested that the obtained results were unlikely to be the product of publication bias and p-hacking alone.Conclusions: Results converge to suggest that, independent of age, affect measure used, and study design, a significant albeit modest relationship between positive affect and alcohol consumption likelihood exists, which does not appear to be the case for negative affect. In conjunction with other recent meta-analyses, current findings help map out a more nuanced understanding of the affect-alcohol/substance use relationship, with potential implications for interventions.


These comprehensive meta-analyses on the impact of within-day affective states on alcohol consumption suggest that increased positive but not negative affect is associated with greater likelihood of alcohol consumption.

RESUMEN

While self-medication and positive and negative reinforcement models of alcohol use suggest that there is an association between daily affect and alcohol consumption, findings within the academic literature have been inconsistent. This pre-registered systematic review meta-analytically interrogated the results from studies amongst non-clinical populations that examine the relationship between daily affective states and alcohol consumption volume. PRISMA guided searches of PsychINFO, PsycARTICLES, Science Direct, PubMed, SCOPUS, and JSTOR databases were conducted. When both laboratory and field studies were included, meta-analyses with robust variance estimation yielded 53 eligible studies on negative affect (8355 participants, 127 effect sizes) and 35 studies for positive affect (6384 participants, 50 effect sizes). The significant pooled associations between intra-day affect and alcohol consumption were r = .09, [.03, .14] for negative affect, and r = .17, [.04, .30] for positive affect. A small-to-medium sized effect (d = .275, [.11, .44]) of negative affect on daily alcohol consumption volume was found in laboratory studies (14 studies, 1100 participants). While publication bias was suspected, P-curve analyses suggested that the results were unlikely to be the product of publication bias and p-hacking alone, and selection model analysis revealed no significant differences in results when publication bias was accounted for. For negative affect, using number of drinks as the measure of alcohol consumption was associated with lower effect sizes. For positive affect, the results demonstrated a decline of this observed effect over time. Overall, findings point towards the possibility of developing an affect intensity regulation theory of alcohol use. Conceptualizing the mood-alcohol nexus in terms of affect intensity regulation may afford a more parsimonious explanation of alcohol consumption rather than viewing the behavior as being shaped by either positive or negative affective states.

RESUMEN

Addressing a relative lack of research investigating the experiences of individuals who have left the Jehovah's Witnesses (JW), this research utilizes a social identity approach to examine qualitatively, the process of transitioning towards post-JW life, experiences of ostracism and perceived threats to self-identity. Semi-structured interviews were carried out in the homes of six former JWs, and transcripts were analysed using interpretive phenomenological analysis. Narratives suggest that experiences of ostracism following religious exit can be associated with diminished mental health, while having a sense of agency and establishing new (online) social connections may help mitigate adverse consequences. Implications and future research directions are discussed.

RESUMEN

Previous research indicates that following alcohol intoxication, activity in prefrontal cortices is reduced, linking to changes in associated cognitive processes, such as inhibitory control, attentional bias (AB), and craving. While these changes have been implicated in alcohol consumption behaviour, it has yet to be fully illuminated how these frontal regions and cognitive processes interact to govern alcohol consumption behaviour. The current preregistered study applied continuous theta burst transcranial magnetic stimulation (cTBS) to examine directly these relationships while removing the wider pharmacological effects of alcohol. A mixed design was implemented, with cTBS stimulation to right and left dorsolateral prefrontal cortex (DLPFC), the medial orbital frontal cortex (mOFC) and Vertex, with measures of inhibitory control, AB, and craving taken both pre- and post-stimulation. Ad libitum consumption was measured using a bogus taste task. Results suggest that rDLPFC stimulation impaired inhibitory control but did not significantly increase ad libitum consumption. However, lDLPFC stimulation heightened craving and increased consumption, with findings indicating that changes in craving partially mediated the relationship between cTBS stimulation of prefrontal regions and ad libitum consumption. Medial OFC stimulation and AB findings were inconclusive. Overall, results implicate the left DLPFC in the regulation of craving, which appears to be a prepotent cognitive mechanism by which alcohol consumption is driven and maintained.

RESUMEN

BACKGROUND: The pharmacological effects of alcohol on executive function, craving and subsequent alcohol-seeking have been well documented. Yet, insufficient methodological controls within existing alcohol administration paradigms have meant that the relative importance of alcohol's pharmacological and anticipatory effects remains in need of further elucidation. AIM: The objective of this study is to disentangle alcohol's pharmacological effects from its anticipatory effects on alcohol-related cognitions and subsequent consumption. METHODS: Inhibitory control, attentional bias and craving were assessed pre- and post-consumption in 100 participants who were randomly allocated to one of four beverage conditions in a two by two design: (1) alcohol aware (alcohol with participant knowledge (pharmacological/anticipation effects)), (2) alcohol blind (alcohol without participant knowledge; in a novel grain alcohol masking condition (pharmacological/no anticipation effects)), (3) placebo (no alcohol but participants were deceived (anticipation/non-pharmacological effects)) and (4) pure control (no alcohol with participant knowledge (no anticipation/non-pharmacological effects)). RESULTS: Findings suggest that the pharmacological effects of alcohol result in greater inhibitory control impairments compared with anticipated effects. Anticipatory but not the pharmacological effects of alcohol were found to increase attentional bias. Both pharmacology and anticipation resulted in increased craving, though higher levels of craving were observed due to alcohol's pharmacology. Furthermore, alcohol pharmacology resulted in heightened ad libitum consumption; however, anticipation did not. Changes in craving partially mediated the relationship between initial intoxication and subsequent drinking, while inhibitory control impairments did not. CONCLUSIONS: Successive alcohol consumption appears driven primarily by the pharmacological effects of alcohol which are exerted via changes in craving.

RESUMEN

AIMS: Previous research indicates that acute alcohol intoxication and placebo can inhibit people's control over consumption behaviour and heighten attentional bias (AB) towards alcohol-related stimuli and craving. We designed a study to disentangle anticipated from pharmacological effects of alcohol in order to gain a clearer view of their relative contributions to alcohol consumption. METHODS: In a within-participants design (moderate alcohol dose, placebo and control), and over a minimum 2-week period, participants completed a battery of questionnaires and cognitive tasks, followed by a bogus taste task to measure ad libitum consumption. RESULTS: Both alcohol preload and placebo resulted in cognitive and psychological changes, including impaired inhibitory control, heightened AB and craving. However, ad libitum consumption only increased following alcohol and not placebo. Furthermore, inhibitory control impairments did not mediate the relationship between initial intoxication and ad libitum consumption, and findings indicate that increases in craving may mediate this association. CONCLUSION: Psychological processes such as craving may be more important in driving consummatory behaviour relative to transient changes in cognitive processes, such as inhibitory control.

RESUMEN

Representing a more immersive testing environment, the current study exposed individuals to both alcohol-related visual and auditory cues to assess their respective impact on alcohol-related inhibitory control. It examined further whether individual variation in alcohol consumption and trait effortful control may predict inhibitory control performance. Twenty-five U.K. university students (Mage = 23.08, SD = 8.26) completed an anti-saccade eye-tracking task and were instructed to look towards (pro) or directly away (anti) from alcohol-related and neutral visual stimuli. Short alcohol-related sound cues (bar audio) were played on 50% of trials and were compared with responses where no sounds were played. Findings indicate that participants launched more incorrect saccades towards alcohol-related visual stimuli on anti-saccade trials, and responded quicker to alcohol on pro-saccade trials. Alcohol-related audio cues reduced latencies for both pro- and anti-saccade trials and reduced anti-saccade error rates to alcohol-related visual stimuli. Controlling for trait effortful control and problem alcohol consumption removed these effects. These findings suggest that alcohol-related visual cues may be associated with reduced inhibitory control, evidenced by increased errors and faster response latencies. The presentation of alcohol-related auditory cues, however, appears to enhance performance accuracy. It is postulated that auditory cues may re-contextualise visual stimuli into a more familiar setting that reduces their saliency and lessens their attentional pull.


Con el objetivo de crear un entorno de evaluación más ajustado a la realidad, en este estudio se expuso a los participantes a estímulos visuales y auditivos relacionados con el alcohol para evaluar su impacto en el control inhibitorio relacionado con el alcohol. Además, se examinó si las diferencias individuales en el consumo de alcohol y el rasgo autorregulación predecían el rendimiento del control inhibitorio. Veinticinco estudiantes universitarios del Reino Unido (edad media = 23,08 años; SD = 8,26) llevaron a cabo una tarea anti-sacádica de seguimiento ocular, en la que se les pedía que miraran hacia (pro), o directamente en la dirección contraria (anti), estímulos visuales tanto relacionados con el alcohol como neutros. Además, en el 50% de los ensayos se reprodujeron estímulos auditivos breves relacionados con el alcohol (sonido de bar), y las respuestas se compararon con las que se producían en la ausencia de sonidos. Los resultados indican que los participantes dirigieron más movimientos sacádicos incorrectos hacia los estímulos visuales relacionados con el alcohol en los ensayos anti-sacádicos, y que respondieron más rápido al alcohol en los ensayos pro-sacádicos. Los estímulos auditivos relacionados con el alcohol redujeron la latencia de respuesta tanto para los ensayos pro- como anti-sacádicos, y redujeron la tasa de errores anti-sacádicos en los estímulos relacionados con el alcohol. Sin embargo, estos efectos se eliminaron al controlar el rasgo autorregulación y el consumo problemático de alcohol. Estos resultados sugieren que los estímulos visuales relacionados con el alcohol pueden estar asociados con una reducción del control inhibitorio, lo cual se pone de manifiesto en el aumento de errores y en unas latencias de respuesta más rápidas. Sin embargo, la presentación de estímulos auditivos relacionados con el alcohol parece aumentar la precisión en la tarea. Se propone que los estímulos auditivos pueden recontextualizar los estímulos visuales en un contexto más familiar que reduce su prominencia y disminuye su capacidad de captar la atención.

RESUMEN

BACKGROUND: Theory of mind (ToM), the ability to understand that others have different knowledge and beliefs to ourselves, has been the subject of extensive research which suggests that we are not always efficient at taking another's perspective, known as visual perspective taking (VPT). This has been studied extensively and a growing literature has explored the individual-level factors that may affect perspective taking (e.g. empathy and group membership). However, while emotion and (dis)liking are key aspects within everyday social interaction, research has not hitherto explored how these factors may impact ToM. METHOD: A total of 164 participants took part in a modified director task (31 males (19%), M age = 20.65, SD age = 5.34), exploring how correct object selection may be impacted by another's emotion (director facial emotion; neutral × happy × sad) and knowledge of their (dis)likes (i.e. director likes specific objects). RESULT: When the director liked the target object or disliked the competitor object, accuracy rates were increased relative to when he disliked the target object or liked the competitor object. When the emotion shown by the director was incongruent with their stated (dis)liking of an object (e.g. happy when he disliked an object), accuracy rates were also increased. None of these effects were significant in the analysis of response time. These findings suggest that knowledge of liking may impact ToM use, as can emotional incongruency, perhaps by increasing the saliency of perspective differences between participant and director. CONCLUSION: As well as contributing further to our understanding of real-life social interactions, these findings may have implications for ToM research, where it appears that more consideration of the target/director's characteristics may be prudent.

RESUMEN

INTRODUCTION: Existing research points to a link between socioeconomic factors, alcohol consumption and harms, while another body of work documents the importance of varying motivations to drink in shaping alcohol behaviours. Yet, little is currently known about the extent to which alcohol consumption may be differentially associated with drinking motives as a function of deprivation, gender and age. METHODS: Cross-sectional analysis of data from a UK sample aged between 18 and 75 years (n = 1639; 51% male, Mage 47.74, SD 14.66). Structural equation modelling, using clustering to account for the multi-level nature of the data set, was carried out to assesses the relationships between deprivation (Index of Multiple Deprivation), occupation, age, gender and problem alcohol consumption (Alcohol Use Disorder Identification Test) and social, conformity, enhancement and coping drinking motives. RESULTS: Coping, enhancement and conformity, but not social, motives were associated with problem alcohol consumption. Drinking motives were stronger predictors of problem consumption than gender and age, with motives tending to be endorsed more strongly by younger and male respondents. Responses from participants with working-class occupations tended to be characterised by elevated endorsements of coping motives. DISCUSSION AND CONCLUSION: Drinking motives are stronger predictors of problem alcohol consumption than socio-demographic variables although these factors exert influences on people's motives to drink.
