RESUMO

BACKGROUND: Nightlife environments are high risk settings for sexual violence and bystander intervention programmes are being developed in response. However, more research is needed to understand nightlife-related sexual violence, and factors that influence bystander interventions. This study examined nightlife patron's experiences of sexual violence and associated factors; and relationships between attitudes towards, awareness and experience of sexual violence, and confidence to intervene. METHODS: Cross-sectional on-street survey of nightlife patrons (N = 307, aged 18+) on a night out in an English city. Surveys (7.30pm-1.30am; Wednesday-Saturday) established sexual violence awareness, myth acceptance, and experience, and confidence to intervene. Participant's socio-demographics, nightlife alcohol consumption, and frequency of nightlife usage were collected. RESULTS: 58.0% had ever experienced sexual violence whilst on a night out. In adjusted analyses, sexual violence was higher amongst females (adjusted odds ratio [AOR] 4.0; p < 0.001), and regular nightlife patrons (AOR 2.1; p < 0.05). The majority agreed that they would feel confident asking someone who has experienced sexual violence if they are okay/would like support (92.2%). In adjusted analyses, confidence to intervene was higher amongst those who agreed that sexual violence was an issue in nightlife (AOR 3.6; p < 0.05), however it reduced as sexual violence myth acceptance increased (AOR 0.5; p < 0.05). CONCLUSION: Sexual violence is a pertinent issue in nightlife. Programmes aiming to address nightlife-related sexual violence must address the wider social norms that promote sexual violence, and ensure patrons understand the extent and significance of the issue, to increase confidence to positively intervene.

RESUMO

Mandatory standardized nutritional information on alcoholic drinks such as energy, or calorie labelling, is a population-level public health measure aimed at addressing obesity and alcohol consumption. In the UK, such measures are not a statutory requirement, but some alcohol brands do include references to calories on their products and in their marketing materials, as a marketing strategy to encourage sales and consumption. This article presents findings of semi-structured individual (N = 43) and group (N = 9) interviews with 78 women living in the UK that aimed to gain insight into their attitudes towards calorie-based alcohol brand marketing, and alcohol calorie labelling (ACL) as a health policy. Three themes are presented that outline how women rejected calorie marketing and labelling; the potential positive and unintended impact on alcohol consumption and dietary/eating practices; and how views on calorie labelling were intertwined with women's attitudes towards marketing that draws on calorie messaging. A feminist anti-diet discourse, as well as a discourse of pleasure through alcohol consumption, was at play in women's accounts, which may limit the intended aims of ACLs. It is concluded that ACLs should be considered within the wider commercial context of alcohol marketing that draws on calories to promote sales and consumption, consideration of the gendered factors that may lead some to reject ACLs as a health policy, and the potential for unintended consequences.

RESUMO

Background: Previous research has shown that People Who Inject Drugs (PWID) are subject to public stigma, which affects access to, and provision and quality of, treatment and support services. Less is known about the socio-cognitive processes that support the development and maintenance of public stigma toward PWID. The present study investigated the role of disgust sensitivity in implicit disgust to injecting drug use. Methods: 126 participants took part in an online Implicit Association Task (IAT) measuring implicit disgust to pictorial stimuli of injecting drug use or medical injecting. Participants also completed The Disgust Scale Revised, Injecting Phobia Scale (Short Form), Attitudes to People Who Use Drugs (PWUD) scale and a substance use inventory. Results: Average IAT score was negative indicating significantly higher implicit disgust to injecting drug use. Hierarchical linear regression found that injecting phobia predicted implicit disgust to injecting drug use. Questionnaire measures of disgust did not predict implicit disgust. While animal reminder disgust and injecting phobia were significantly correlated with each other, animal reminder disgust did not predict implicit disgust scores. Conclusions: On the basis of our findings, stigma toward PWID may not be a result of feelings of disgust toward injecting drug use. We discuss findings in the context of the underlying cortical processes supporting implicit and explicit representations of disgust. Future research should seek to investigate neurophysiological evidence for disgust to and stigmatization of injecting drug use and the potential role of domains of disgust in this.

RESUMO

BACKGROUND: The pinking of alcohol products and marketing (i.e. the (over) use of the colour pink as a feminine aesthetic) is a form of gendered marketing that is used by the industry to target and appeal to the female market, and encourage sales and alcohol consumption. However, little is known about how women relate to and view such marketing, and how such products feature in their performance of femininities through drinking practice. METHODS: Semi-structured individual (N = 39) and group (N = 79) interviews with 117 women who drank alcohol and participated in the night time economy in the city of Liverpool in North West of England were conducted to gain insight into their attitudes towards the use of pink in alcohol product design and marketing content, and how this relates to their feminine identity making in intersectional ways. Interviews with individuals (N = 23) working in alcohol brand marketing locally, nationally and globally were also conducted to explore the use of pink marketing. Data were analysed using thematic analysis. FINDINGS: The pinking of products and marketing was considered the most obvious form of female targeted marketing by both women and marketers. Discussion of pink drinks generated in depth discussions of the femininities and connotations attached to the colour. Reflecting a conventional and normative femininity, women conformed to, and/or rejected pink products and marketing, within their feminine identity making. Four themes are presented that draw attention to the similarities and differences between marketers and women's perspectives on pink marketing, and how women's relationship with pink marketing and products were nuanced, varied in relation to their feminist identities, and intersected with other social positions such as sexuality and class. CONCLUSION: The article makes an original and significant contribution to the field on gendered drinking practices and identity making and the influence of alcohol marketing on these processes, and is novel in addressing the usual omission of industry voice in discussions of marketing. It concludes that in the current context of contemporary feminism, in which (young) women are endorsing feminist identities, women's relationship with feminism influences their attitudes to marketing such as pinking, and their likelihood of consuming such products.

RESUMO

BACKGROUND AND AIMS: A health warning label (HWL) cautioning about the link between alcohol and cancer may be able to communicate alcohol risks to consumers and potentially counter health-oriented nutrition advertising on ready-to-drink alcoholic beverages. This study aimed to examine the independent and combined effects of nutrient content claims (e.g. 0 g sugar) and a HWL on perceived product characteristics and intentions to consume, and whether these effects differed by gender and age. DESIGN: A between-subjects randomized experiment. Participants were randomized to view one of six experimental label conditions: nutrient content claims plus nutrition declaration (NCC + ND), ND only, NCC + ND + HWL, ND + HWL, HWL only and no NCC, ND or HWL, all on a ready-to-drink (RTD) vodka-based soda container. SETTING AND PARTICIPANTS: Alcohol consumers (n = 5063; 52% women) in Canada aged 18-64 recruited through a national online panel. MEASUREMENTS: Participants completed ratings of perceived product characteristics, perceived product health risks, and intentions to try, buy, binge and drink the product. FINDINGS: Compared with the reference condition NCC + ND (current policy scenario in Canada), the other five experimental label conditions were associated with lower ratings for perceiving the product as healthy. All experimental conditions with a HWL were associated with lower product appeal, higher risk perceptions and reduced intentions to try, buy and binge. The experimental condition with a HWL only was associated with intentions to consume fewer cans in the next 7 days (ß = -0.72, 95% confidence interval [CI] = -1.37,-0.08) versus the reference. Few interactions were observed, suggesting that label effects on outcomes were similar by gender and age. CONCLUSIONS: Health warning labels on alcohol packaging appear to be associated with lower product appeal, higher perceived health risks and reduced consumption intentions, even in the presence of nutrient content claims.

RESUMO

BACKGROUND: In recent years, reductions in drinking in the UK and the rise of online 'positive' sobriety communities have been observed, yet peer led support groups such as Alcoholics Anonymous (AA) and neo-liberal discourses of control and responsibility dominate public understandings of (problematic) alcohol use. This paper presents research exploring how women active in the 'positive sobriety' community on Instagram position and construct their non-drinking identities and relationships with alcohol within these overlapping discourses. METHODS: Semi-structured interviews (n=15) and online content produced by women active in the positive sobriety community on Instagram were analysed using thematic analysis. FINDINGS: Women challenged, reproduced and amalgamated AA discourses of addiction, and the broader discourses of neo-liberalism, in ways that positioned (alcohol) consumption, agency, control and individual responsibility as defining features of feminine identity making. Drawing on these discourses, binary understandings of problematic drinking, the identity of the 'alcoholic', and the need to reach 'rock bottom' in the recovery process were rejected and challenged, but at times reproduced. Whilst a broader framing of problematic drinking that situated drinking problems on a spectrum was constructed, abstinence was engaged with and promoted as the most effective way of gaining control and responsibility over drinking in gendered ways, and in establishing an authentic sense of self. CONCLUSION: This paper contributes to emerging research on online 'positive' sobriety communities, their gendered nature, and the intertwined presence of traditional recovery and neo-liberal discourses in women's accounts. Online sober communities offered alternative spaces of support and allowed for sobriety and sober femininities to be framed more positively than within traditional AA conceptualisations. However, those involved may experience tensions around (a) the need to 'tell' their personal stories of complete abstinence whilst still appealing to those who seek to 'moderate' and (b) the pressure to create and craft an 'authentic' sober self on an online platform that demands a carefully curated self-image and personal 'brand'. Further research should aim to gain more understanding of the role social media plays in "doing" sobriety and non-drinking, how this is done by people of different genders, the intersectional experiences of those participating, and how these communities can be made more equally available and accessible to those who do not consider full abstinence as necessary, whilst still appealing to those that do.

RESUMO

BACKGROUND: Drug related deaths (DRD) are at historically high levels in the United Kingdom (UK), but some approaches that have the potential to reduce risk of mortality remain controversial. Public support makes an important contribution to drug policy development but there are high levels of public stigma towards people who use drugs (PWUD), and this is partly shaped by media representations. We investigated whether depiction of the characteristics of decedents represented in news articles about DRD was associated with differences in stigmatising attitudes and support for harm reduction policy. METHODS: We undertook a cross-sectional online study with a randomised design, conducted with a nationally representative sample (UK). Participants (N = 1280) were randomly presented with one of eight simulated news stories that reported on a DRD that differed with respect to drug (ecstasy or heroin), and the gender (male or female) and age (younger or older) of the decedent. Data were analysed using MANOVA. RESULTS: Data were obtained for 1248 participants (51.0% female; mean age 45.7±15.4). Stigma was higher towards depictions of male, older, and heroin deaths (all p < .001). Harm reduction support was higher in those participants seeing older compared to younger subjects (p = .035), and the older ecstasy decedent compared to younger decedent (p = .029). CONCLUSION: Presentation of some types of DRD are associated with higher public stigma towards the decedent than others. Those groups developing agenda-setting activities designed to reduce stigma or foster public support for harm reduction policies should consider the different ways in which audiences may respond to the depiction and framing of DRD in news media.

RESUMO

BACKGROUND: Adolescent smoking is a significant public health concern in the UK and across Europe. This study examines smoking behaviours, methods of accessing cigarettes and use of non-commercial (fake, foreign and single) cigarettes across a sample of schoolchildren. Relationships with alcohol consumption, deprivation, personal income and extra-curricular activities are also explored. METHODS: A cross-sectional survey of 9833 15- and 16-year-old schoolchildren in the North West of England. RESULTS: Cigarettes were most commonly accessed from off-licences and newsagents, but pupils also reported non-commercial access through friends, family and street sellers/neighbours. A high percentage of smokers had bought foreign (57%), fake (28%) and single (54%) cigarettes. Frequent binge drinking, not participating in extra-curricular activities, receiving greater personal income, and having parents that smoked were significantly associated with being a regular and heavier smoker. Frequent binge drinking was also significantly associated with buying foreign/fake or single cigarettes. A higher percentage of those living in deprived areas were current smokers, although deprivation was not an independent predictor of cigarette use. CONCLUSION: Strategies that restrict commercial access to cigarettes among adolescents may increase their reliance on social methods of access, and use of fake, foreign and single cigarettes. Interventions to reduce adolescent smoking must recognize the critical role of parents and communities in discouraging smoking and preventing social access to cigarettes in children. A joint approach to prevention is required that targets children at risk of smoking, heavy alcohol use and associated health-damaging behaviours.

RESUMO

BACKGROUND: The closure of on-licence premises and the restrictions placed on citizen's movements and leisure to address the COVID-19 pandemic in 2020, created an unprecedented situation for the alcohol industry. With the availability and supply of alcohol being restricted, and the social context of alcohol use transformed, alcohol corporations were required to adapt their marketing materials and actions in response. METHODS: A content analysis of alcohol marketing by 18 alcohol brands on Facebook and Instagram during the first UK national lockdown (from 17th March- 4th July 2020) was conducted. Comments left by social media followers on posts advertising what could be defined as brand COVID-19 Corporate Social Responsibility (CSR) initiatives (i.e. monetary donations, production of hand sanitiser) were thematically analysed. FINDINGS: Alcohol brands quickly adapted to the changing social, economic and health context of the global pandemic. Changes to the availability and sale of alcohol were evident, with brands encouraging the stockpiling of alcohol as an essential item through predominantly online sales and delivery services. Brands also adapted to the changing social and physical context of alcohol use and intensified encouragement of home drinking. Messages of togetherness underpinned the promotion of virtual interactions, for which alcohol use was presented as a key component. Consumers were encouraged to contribute to pandemic responses by 'staying at home', and consuming alcohol. Importantly, COVID-19 provided a useful marketing opportunity for alcohol producers to present themselves as private partners to a primarily public sector response, through innovative CSR initiatives such as philanthropic donations to help prevent the transmission of COVID-19. An inductive thematic analysis of online comments on CSR posts found that such activities were interpreted by consumers as ethical actions, and that they reinforced positive brand image and loyalty amongst existing and new consumers. CONCLUSION: Alcohol corporations are highly resilient in times of crises and the brands analysed were able to quickly adapt their marketing to the COVID-19 pandemic. Future research is required to examine whether these profitable strategies are maintained post pandemic.

RESUMO

The growing diversity and uptake of social media has increased the sources of health information available to young people. YouTube is one of the most popular social media platforms for young people in the United Kingdom, and YouTubers are the most important influencers on the platform producing diverse health content. They are increasingly recognized by popular media and public health organizations as a potentially influential source of health information for young people. This study aimed to qualitatively explore young people's experiences and perceptions of YouTuber health content. Focus groups (November 2017 to January 2018) with 85 young people (13-18 years) were recruited from schools in a single county in North West England. The findings suggest young people's engagement with YouTuber health content is dependent on how they encounter it, YouTubers' motivations for producing it, and the perceived relatability, sincerity, and generalization present in this content. The study confirms YouTuber health content was one of the many sources of health information used by young people and was most frequently encountered during young people's routine viewing. Collaboration between public health organizations and YouTubers could be promising in communicating health messages to young people already engaged with these YouTubers, as part of wider campaigns or interventions. These messages could be particularly effective if they focused on experiences and norms rather than advice, remained consistent with YouTubers' existing health content, incorporate clear indicators of accuracy into their narrative, and state their intention to benefit young people.

RESUMO

BACKGROUND: The data on the COVID-19 patients who were discharged to self-quarantine is lacking. AIM: The aim of the study was to investigate the percentage of COVID-19 positive patients that were hospitalized within a three-week period after discharge from ED to self-quarantine. METHODS: The patients who had confirmed SARS-CoV-2 on RT-PCR of the nasopharyngeal swab and were discharged from ED of a tertiary care hospital in the USA to self-quarantine from March 01- July 31, 2020, were included. Patients were divided into two groups based on serum albumin levels and were followed up for three weeks to see if low level of albumin increased the risk of hospitalization. Univariate and multivariate logistic regression analyses were performed to study the effect of albumin level and outcomes. RESULTS: A total of 112 patients were included in the study out of which 65 had low serum albumin (<3.5 g/dL) and 47 had normal serum albumin (≥3.5 g/dL). More than 10% of patients discharged to self-quarantine needed hospitalization within three weeks. The Low albumin group had more co-morbidities at baseline. The low serum albumin group had 10 (15.38%) vs 2 (4.26%), p = 0.06 hospitalizations as compared to the normal serum albumin group. The multivariate logistic regression analysis did not reveal lower odds of hospitalization in the group with normal albumin, (OR 0.26, 95% CI 0.03-1.92, p = 0.19) after controlling for age, sex, and various co-morbidities. CONCLUSION: The low serum albumin was not associated with the risk of hospitalization in COVID-19 patients who were initially discharged to self-quarantine.

RESUMO

BACKGROUND: To address rising drug-related harms (including significant transmission of HIV) among people who inject drugs (PWID) in Glasgow, officials have proposed the introduction of the UK's first drug consumption room (DCR) in Glasgow city centre. Using a nationally representative sample, this study aimed to determine willingness to use a DCR among PWID nationally, in Glasgow city centre (the proposed DCR location), other Scottish city centres (excluding Glasgow) and the rest of Scotland (excluding city centres). METHODS: Bio-behavioural survey, of 1469 current PWID (injected in last 6 months) across Scotland during 2017-18. Willingness to use DCRs was examined by drug-related risk behaviours and harms overall in Scotland, and then stratified by Glasgow city centre (n = 219), other Scottish city centres (n = 226) and the rest of Scotland (n = 1024). RESULTS: The majority of PWID overall in Scotland (75%) were willing to use a DCR; willingness was higher among those recruited in Glasgow city centre (83%) and other Scottish city centres (83%), compared to the rest of Scotland (72%) (p < 0.001). Willingness was greater among PWID who reported (compared to those who did not report) injecting heroin (76%, p = 0.002), cocaine injecting (79%, p = 0.014), homelessness (86%, p < 0.001), public injecting (87%, p < 0.001) and an overdose (80%, p = 0.026). Willingness was found to be associated with a cumulative multiple risk variable: increased from 66% among those with a score of zero to 85% with a score of at least three (p < 0.001). CONCLUSIONS: The vast majority of PWID at greatest risk of drug-related harm in Glasgow and elsewhere in Scotland would be willing to use a DCR, supporting proposals for the introduction of DCRs nationally.

RESUMO

BACKGROUND: Synthetic cannabinoids (SCs) are a class of new psychoactive substances that have been rapidly evolving around the world throughout recent years. Many different synthetic cannabinoid analogues are on the consumer market and sold under misleading names, like "spice" or "incense." A limited number of studies have reported serious health effects associated with SC use. In this study, we compared clinical and subclinical psychopathological symptoms associated with SC use and natural cannabis (NC) use. METHODS: A convenience sample of 367 NC and SC users was recruited online, including four validated psychometric questionnaires: The Drug Use Disorders Identification Test (DUDIT), Insomnia Severity Index (ISI), Altman Mania Scale (Altman), and Brief Symptom Inventory (BSI). The two groups were compared with analysis of variance (ANOVA) and covariance (ANCOVA), chi2 tests, and logistic regression when appropriate. RESULTS: The SC user group did not differ in age from the NC user group (27.7 years), but contained less females (21% and 30%, respectively). SC users scored higher than NC users on all used psychometric measures, indicating a higher likelihood of drug abuse, sleep problems, (hypo)manic symptoms, and the nine dimensions comprising the BSI, somatization, obsessive-compulsive behavior, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, and psychoticism. Odds ratios (95% CI) for the SC user group vs NC user group were, respectively, drug dependence 3.56 (1.77-7.16), (severe) insomnia 5.01 (2.10-11.92), (hypo-)mania 5.18 (2.04-13.14), and BSI psychopathology 5.21 (2.96-9.17). DISCUSSION: This study shows that SC use is associated with increased mental health symptomatology compared to NC use.

RESUMO

Background: Going without sleep for long periods of time can produce a range of experiences, including perceptual distortions and hallucinations. Many questions, however, remain unanswered regarding the types of symptoms which are most reliably elicited, the time of symptom onset, and whether symptoms worsen over time toward psychotic decompensation. Since sleep deprivation exceeding 48 h is considered unethical today, an examination of historical studies with extreme sleep-loss duration is needed to obtain information about what happens during prolonged sleep loss. Methods: A systematic-review approach was used to identify experimental and observational studies of sleep deprivation in healthy people which describe the effects of prolonged sleep loss on psychopathological symptoms, without any date restriction. Results: A total of 476 articles were identified. Of these, 21 were eligible for inclusion. Duration of sleep loss ranged between 24 h and 11 nights (total 760 participants; average 72-92 h without sleep). All studies except one reported perceptual changes, including visual distortions (i.e., metamorphopsias), illusions, somatosensory changes and, in some cases, frank hallucinations. The visual modality was the most consistently affected (in 90% of the studies), followed by the somatosensory (52%) and auditory (33%) modalities. Symptoms rapidly developed after one night without sleep, progressing in an almost fixed time-dependent way. Perceptual distortions, anxiety, irritability, depersonalization, and temporal disorientation started within 24-48 h of sleep loss, followed by complex hallucinations and disordered thinking after 48-90 h, and delusions after 72 h, after which time the clinical picture resembled that of acute psychosis or toxic delirium. By the third day without sleep, hallucinations in all three sensory modalities were reported. A period of normal sleep served to resolve psychotic symptoms in many-although not all-cases. Conclusions: Psychotic symptoms develop with increasing time awake, from simple visual/somatosensory misperceptions to hallucinations and delusions, ending in a condition resembling acute psychosis. These experiences are likely to resolve after a period of sleep, although more information is required to identify factors which can contribute to the prevention of persistent symptoms.

RESUMO

BACKGROUND: New psychoactive substances (NPS) are on offer worldwide online, in order to shed light on the purity and price of these substances in the European Union, a research collaboration was set up involving France, United Kingdom (UK), the Netherlands, Czech Republic and Poland. METHODS: Per country, around 10 different NPS were test purchased from different webshops. Then, chemical analysis of NPS was done with according reference standards to identify and quantify the contents. RESULTS: In contrast to what is generally advertised on the webshops (>99%), purity varied considerably per test purchased NPS. Several NPS were mislabelled, some containing chemical analogues (e.g. 25B/C-NBOMe instead of 25I-NBOMe, pentedrone instead of 3,4-DMMC). But in some cases NPS differed substantially from what was advertised (e.g. pentedrone instead of AMT or 3-FMC instead of 5-MeO-DALT). Per gram, purity-adjusted prices of cathinones differed substantially between three countries of test purchase, with Poland being the least expensive. Synthetic cannabinoids were relatively the most expensive in the Czech Republic and least expensive in the UK. CONCLUSION: The current findings provides a snapshot of the price and chemical contents of NPS products purchased by different countries and in different webshops. There is a potential danger of mislabelling of NPS. The great variety in price and purity of the delivered products might be the result of the market dynamics of supply and demand and the role of law enforcement in different European countries.

RESUMO

BACKGROUND: Young women in the UK often partake in a culture of intoxication in the pursuit of pleasure and friendship fun. Experiences of intoxication and drinking spaces remain highly gendered, and relative to men, women continue to find their behaviours in drinking spaces more constrained and scrutinised. Simultaneously, young women now express themselves via Social Network Sites (SNS), where they display drinking experiences and where they perform, negotiate and display contemporary femininities. METHODS: The research explored young women's experiences of drinking and intoxication, the use of SNS in their drinking cultures and the display of drinking practices on SNS through group interviews (n=12) with women (n=37) aged 16-21 from one city in the North-West of England, UK. RESULTS: The practice of uploading drinking photographs to SNS played an important role in displaying young women's popularity, enhancing friendship fun and belonging, and in positioning the hyper-sexual feminine look as the norm in drinking spaces. Both intoxication and the hyper-sexual and feminine look challenged traditional notions of respectable femininity, while the highly groomed feminine look itself was threatened by drunkenness. As such, young women invested much work and effort in self-surveillance and in managing the display of their drinking behaviours on SNS. CONCLUSION: The dilemmas in contemporary femininity created by the juxtaposition of hyper-sexual femininity and the culture of intoxication are reproduced on SNS. Controlling and restricting certain content on SNS with the aim of achieving the 'right' feminine self-presentation resulted in a narrowly set of body oriented and behavioural feminine attributes being presented as the norm, and an overly positive online representation of young women's drinking experiences.

RESUMO

Symptoms of psychosis such as hallucinations and delusions can be intrusive and unwanted and often remain treatment-resistant. Due to recent progress in basic and clinical sciences, novel approaches such as sleep-based interventions are increasingly becoming offered to address the physical and mental health issues of people with severe mental illness. While the primary outcome is to improve sleep, studies have demonstrated that interventions that target symptoms of insomnia can also produce improvements in the severity of psychotic symptoms, quality of life, and functional outcomes. This study presents qualitative data on the attitudes and preferences of people with schizophrenia and schizo-affective disorders to three different types of therapies for insomnia (standard pharmacological, melatonin-based, and cognitive and/or behavior therapy). Interviews included discussions regarding the perceived advantages and limitations of different therapies, enablers to taking up the preferred option, as well as personal strategies that have helped respondents with sleep problems in the past. Results showed that, when given the choice, these individuals prefer psychological and behavioral-type therapy to other sleep interventions because of its potential to support and empower them in taking responsibility for their own recovery. Pharmacological therapies, by contrast, are viewed as useful in managing acute sleep problems, but only as a short-term solution. Overall, the findings underscore the need for patients' active engagement when making decisions about treatment options.

RESUMO

Drinking environments, including bars, nightclubs and their surrounds are associated with high levels of acute alcohol-related harms. This systematic review examined the effectiveness of interventions implemented in drinking environments to reduce alcohol use and associated harms. The findings of the review were limited by the methodological shortcomings of the included studies. However, three studies indicated that multicomponent programmes combining community mobilisation, RBS training, house policies and stricter enforcement of licensing laws may be effective in reducing assaults, traffic crashes, and underage sales depending on the focus of the intervention. The effectiveness of other intervention approaches was limited. Future studies of interventions in drinking environments should focus on using appropriate and robust study designs.

RESUMO

BACKGROUND: Drug and alcohol users have an 'attentional bias' for substance-related cues, which is likely to reflect the incentive-motivational properties of those cues. Furthermore, administration of an alcohol preload increases attentional bias for alcohol and tobacco-related cues in heavy drinkers and tobacco smokers, respectively. The present study investigated attentional bias for cocaine cues in cocaine users and non-users following administration of either alcohol or placebo. METHOD: Thirty-two regular cocaine users and 40 non-users took part. Participants were administered alcohol or placebo, and administration was double blind. After drink administration, a Visual Probe task and Modified Stroop task were used to assess attentional bias. Subjective craving and alcohol outcome expectancies were also measured. RESULTS: There was a significant interaction between group and drink type on the visual probe task indicating that cocaine users who had received alcohol had increased attentional bias for cocaine pictures compared to non-users and cocaine users who received placebo. The cocaine Stroop revealed no differences between cocaine users and non-users, and no effects of alcohol in either group. CONCLUSIONS: Alcohol preload in regular cocaine users increases attentional bias for cocaine cues. However, cocaine users who received placebo did not show attentional bias for cocaine stimuli. Future research should investigate the effects of alcohol preload on attentional bias in cocaine-dependent individuals.
