Attitudes towards alcohol dependence and affected individuals: persistence of negative stereotypes and illness beliefs between 1990 and 2011

Efficacy of medications for the treatment of alcohol use disorder (AUD): A systematic review and meta-analysis considering baseline AUD severity

Baseline severity of alcohol use disorder (AUD) is an influencing factor in the response to medications recommended for the treatment of AUD. The scarce efficacy of AUD medications partly justifies their limited uses. We were interested in evaluating the efficacy of approved and recommended AUD medications using generic inverse-variance, an analysis facilitating comparison between medications and placebo both at the end of the study and, concomitantly, to baseline values for the same participants. We conducted a systematic review to include randomized controlled trials (RCTs) comparing any medication to placebo providing, both at baseline and end of treatment, percent heavy drinking days (%HDD), percent drinking days (%DD), and/or drinks per drinking day (DDD). We searched PubMed, Embase, PMC, and three CT registers from inception to April 2023. A total of 79 RCTs (11,737 AUD participants; 30 different medications) were included: 47 RCTs (8465 participants) used AUD medications, and 32 RCTs (3272 participants) used other medications. At baseline, participants consumed on average approximately 12 DDD, and experienced 70 % DD, and 61 % HDD. Placebo halved or reduced these values to a third. Compared to placebo, AUD medications further reduced these outcomes (moderate to high certainty evidence). Other medications reduced the DDD without modifying other alcohol outcomes. AUD medications increased the risk of developing adverse events (high-certainty evidence). Despite the large placebo effects, our results support the benefits of providing AUD medications to people with AUD, helping them reduce alcohol consumption.

Treatment Referrals Post-prohibition of Alcohol Exclusion Laws: Evidence from Colorado and Illinois

BACKGROUND

Individuals with alcohol-related disorders often encounter barriers to accessing treatment. One potential barrier is the state alcohol exclusion laws (AELs) that allow insurers to deny coverage for injuries or illnesses caused by alcohol intoxication. Several states have repealed AELs by prohibiting them completely, including banning exclusions in health and accident insurance policies, limiting their scope, or creating exemptions.

OBJECTIVES

To examine whether prohibiting alcohol exclusions in health and accident insurance policies is associated with alcohol-related treatment admissions.

DESIGN

We used the 2002 to 2017 Treatment Episode Data Set and obtained data from several sources to control for state-level factors. We employed a heterogeneous difference-in-differences method and an event study to compare the treatment admissions in Colorado and Illinois, two states that uniquely repealed AELs, with control states that allowed or had no AELs.

MAIN MEASURES

We used aggregated alcohol treatment admission for adults by healthcare referral: (i) with alcohol as the primary substance and (ii) with alcohol as the primary, secondary, or tertiary substance.

KEY RESULTS

We found a significant relationship between AEL repeal and increased referrals. AEL repeal in Colorado and Illinois was associated with higher treatment admissions from 2008 to 2011 (average treatment effect on the treated: 2008 = 653, 2009 = 1161, 2010 = 1388, and 2011 = 2020). We also found that a longer duration of exposure to AEL repeal was associated with higher treatment admissions, but this effect faded after the fourth year post-treatment.

CONCLUSIONS

Our study reveals a potential positive association between the repeal and prohibition of AELs and increased alcohol-related treatment admissions. These findings suggest that states could enhance treatment opportunities for alcohol-related disorders by reconsidering their stance on AELs. While our study highlights the possible public health benefits of repealing AELs, it also paves the way for additional studies in this domain.

AUD in perspective

Alcohol is a major cause of pre-mature death and individual suffering worldwide, and the importance of diagnosing and treating AUD cannot be overstated. Given the global burden and the high attributable factor of alcohol in a vast number of diseases, the need for additional interventions and the development of new medicines is considered a priority by the World Health Organization (WHO). As of today, AUD is severely under-treated with a treatment gap nearing 90%, strikingly higher than that for other psychiatric disorders. Patients often seek treatment late in the progress of the disease and even among those who seek treatment only a minority receive medication, mirroring the still-prevailing stigma of the disease, and a lack of access to effective treatments, as well as a reluctance to total abstinence. To increase adherence, treatment goals should focus not only on maintaining abstinence, but also on harm reduction and psychosocial functioning. A personalised approach to AUD treatment, with a holistic view, and tailored therapy has the potential to improve AUD treatment outcomes by targeting the heterogeneity in genetics and pathophysiology, as well as reason for, and reaction to drinking. Also, the psychiatric co-morbidity rates are high in AUD and dual diagnosis can worsen symptoms and influence treatment response and should be considered in the treatment strategies.

Stigma and self-stigma among women within the context of the german "zero alcohol during pregnancy" recommendation: A qualitative analysis of online forums and blogs

BACKGROUND

In many countries, including Germany, it is recommended to abstain from alcohol during pregnancy to avoid harm to the baby. In this qualitative research study, analysis of online forums was conducted to explore women's perception of the German "zero alcohol during pregnancy" recommendation with regard to stigma and self-stigma.

METHODS

We used a grounded theory approach to analyze online forum discussions on alcohol use during pregnancy. Data consisted of 9 discussion threads from 5 different forums and blogs involving 115 participants in total. We used key concepts developed during analysis and the theory of stigma to interpret the posts.

RESULTS

We identified five key themes: (1) Low alcohol health literacy as a breeding ground for stigmatization; (2) The widespread assumption that maternal abstinence is a prerequisite for being considered a "good mother"; (3) Interpersonal role conflicts and a guilty conscience as a result of stigmatization or self-stigmatization; (4) Paying little attention to the role of psychosocial factors in alcohol consumption, especially regarding partner responsibility during pregnancy.; (5) Understanding the "zero alcohol during pregnancy" recommendation as a complete ban, associated with loss of autonomy.

CONCLUSION

The current method of communicating the "zero alcohol during pregnancy" recommendation may have unintended consequences. Specifically, misconceptions about the harm associated with low alcohol consumption and setting high expectations of motherhood are factors that can contribute to stigma or self-stigma and potentially undermine self-efficacy, help-seeking behavior, and overcoming the barriers to alcohol health literacy.

(Mis)understanding alcohol use disorder: Making the case for a public health first approach

'Alcohol use disorder' (AUD) is used by several contemporary conceptualizations to identify, treat and prevent problems associated with alcohol use. Such conceptualizations encompass diagnostic classifications and broader frameworks for policy and practice. However, current AUD concepts are subject to multiple tensions and limitations in capturing and responding to the complex and heterogeneous nature of alcohol problems. Further, public understandings of alcohol problems are heavily divergent from professional AUD concepts and remain embedded within an 'alcoholism' master narrative in which disease model stereotypes come with multiple costs for prevention and 'recovery'. The persistence of a problematic 'alcoholism' paradigm reflects the coalescing of multiple forces including the cognitive appeal of reductionism, motives to stigmatize and 'other', and an over-emphasis on AUD as an individually located biomedical problem. Public misperceptions of AUD as a matter of the individual, the individual's essence, and misconceived notions of responsibility and control have been bolstered by industry interests and the ascension of neuroscience and genetics, in turn diverting attention from the importance of the environmental and commercial determinants of health and the effectiveness of under-utilized public health policies. We call for multiple stakeholders to support efforts to prioritize a public health first approach to advancing AUD research, policy and treatment in order to make significant advances in AUD prevention and treatment. We offer several recommendations to assist in shifting public understanding and scientific limitations in AUD concepts and responses.

Health claims denial for alcohol intoxication: State laws and structural stigma

BACKGROUND

Some alcohol exclusion laws (AELs) allow health insurers to deny coverage to individuals injured due to being intoxicated. Evidence has shown that such AELs disincentivize health-care providers to screen for alcohol while they deter treatment utilization by people with an alcohol use disorder (AUD). Certain states have changed AELs to enhance the health of people with an AUD, but these changes are not well documented in the extant literature. This study examined the current status and historical trends in AELs across US states.

METHODS

We conducted a systematic legal analysis in 2023 to examine how state alcohol exclusion laws vary across the United States. These laws allow or prohibit insurers from denying coverage for injuries or deaths related to alcohol use. We classified the states into three categories: (1) States that explicitly permit alcohol exclusions, (2) States that explicitly ban alcohol exclusions, and (3) States that have no clear policy on alcohol exclusions.

RESULTS

We found that 18 states still have alcohol exclusion laws, down from 37 in 2004. Meanwhile, the number of states that have explicitly banned AELs and prohibited insurers from applying alcohol exclusions (AEs) to their policies has increased from 3 to 15 in the same period. The remaining 17 states have no clear laws on AEs. We also noted that five states that repealed their AELs did not adopt any specific prohibition on AEs, and four states limited their prohibition to policies that cover hospital, medical, or surgical expenses.

CONCLUSIONS

Our systematic mapping reveals that some states have prohibited AELs in response to their detrimental effects. However, some states maintain these policies, and none has effectively outlawed AEs in the last 10 years, despite their possible role in reinforcing stigma.

The dual role dilemma of liver transplantation health care professionals

BACKGROUND

Similar to many other countries, in Germany patients with alcohol-related liver disease are obliged to prove their abstinence before being accepted on a waitlist for liver transplantation. Health care professionals (HCPs) must both treat patients and ensure that patients have proven their abstinence. The aim of this exploratory study was to develop a deeper understanding of how HCPs deal with this dual role.

METHODS

The study used semi-structured interviews as the source of data. 11 healthcare professionals from ten of the 22 German transplant centers were interviewed. After transcription, a qualitative content analysis was performed.

RESULTS

We found that these HCPs faced an ethical dilemma, as they must balance the roles of being both a treatment provider (the therapist role) and an assessor (the monitoring role). To solve this dilemma, the strategy seems to be a tendency for the HCPs to take on one dominant role amongst these two roles. HCPs who prefer to take on the therapist role seem to feel burdened by the 6-month abstinence rule and the obligation to monitor their patients. HCPs who prefer to take on the monitoring role tend to have negative assumptions about the patients. HCPs also reported the impression that patients perceive HCPs as more involved in monitoring and less open to the therapeutic role. From this it can be deduced that current regulations and structures lead both to stress for HCPs and to suboptimal therapy for those affected.

CONCLUSIONS

The results showed that current transplantation guidelines can have a negative impact on both patient care and the burdens on the HCPs. From our point of view, there are various changes that could be made to the current clinical practice that would help solve this dilemma. For instance, integrating other assessment criteria that are more closely adapted to the health status trajectory and psychosocial background of the individual patient would be both possible and would lead to improvements in practice.

Should responsibility be used as a tiebreaker in allocation of deceased donor organs for patients suffering from alcohol-related end-stage liver disease?

There is a long-standing debate concerning the eligibility of patients suffering from alcohol-related end-stage liver disease (ARESLD) for deceased donor liver transplantation. The question of retrospective and/or prospective responsibility has been at the center of the ethical discussion. Several authors argue that these patients should at least be regarded as partly responsible for their ARESLD. At the same time, the arguments for retrospective and/or prospective responsibility have been strongly criticized, such that no consensus has been reached. A third option was proposed as a form of compromise, namely that responsibility should only be used as a tiebreaker in liver allocation. The present study provides an ethical investigation of this third option. First, we will provide an overview of the main arguments that have been offered for and against the use of responsibility as an allocation criterion. Second, we will explore the concept of responsibility as a tiebreaker in detail and discuss several types of situations, in which responsibility could be used as a tiebreaker, as well as the main ethical challenges associated with them. As we will show, an ethical justified use of responsibility as a tiebreaker is limited to a very restricted number of cases and is associated with a number of ethical concerns. For this reason, waiting time should be preferred as a tiebreaker in liver allocation, even though the criterion of waiting time, too, raises a number of equity-related concerns.

Should we promote alcohol problems as a continuum? Implications for policy and practice

The highly heterogeneous nature of alcohol use and problems has presented significant challenges to those attempting to understand, treat or prevent what is commonly termed alcohol use disorder (AUD). However, any attempts to capture this complex phenomenon, including the various current criterion of AUD, come with a number of limitations. One particular limitation has been how alcohol problems are represented or understood in ways which do not capture the broad spectrum of alcohol use and harms and the many potential routes to prevention, treatment, and recovery. One possible response to this has been proposed as more explicitly framing or conceptualizing a continuum model of alcohol use and harms. In this commentary, we attempt to identify the key implications of a continuum model for policy and practice, examining the historical and current context of alcohol problem classifications and models. We argue a continuum model of alcohol use and problems holds a number of advantages for advancing public health goals, but also some potential limitations, both of which require further examination.

A novel community-based therapeutic education program for reducing alcohol-related harms and stigma in people with alcohol use disorders: A quasi-experimental study (ETHER study)

INTRODUCTION

Alcohol use disorder (AUD) is associated with a significant disease burden in France, where alcohol use is deeply rooted in culture. However, the treatment gap is large because of several barriers, including stigmatisation and drinkers' apprehension about total abstinence. However, standardised and evidence-based interventions based on controlled-drinking for people with AUD are lacking. We aimed to assess the effectiveness of a novel community-based French therapeutic patient education (TPE) program for people with AUD named Choizitaconso.

METHODS

A before-after non-randomised quasi-experimental study, named ETHER, was designed and implemented with people living with AUD, over a period of 6 months. The primary outcome was percentage change in the number of alcohol-related harms experienced. Secondary outcomes were percentage changes in psycho-social patient-reported and community-validated outcomes. Participants in the intervention group (n = 34) benefited from the 10-week TPE program Choizitaconso, while the comparison group (n = 58) received standard care. The Kruskall-Wallis and chi-squared or Fisher's exact tests were used to compare before-after changes in variables in both groups. Linear regression models were used to test for the effect of study group on each outcome and to test for the effect of alcohol consumption as a confounder.

RESULTS

At 6 months, all outcomes but one either remained stable or numerically improved in both groups. Internalised stigma significantly improved in the intervention group (p = 0.026) but not in the comparison group (p = 0.207), with a significant group effect (p = 0.014).

DISCUSSION AND CONCLUSIONS

This study demonstrates the effectiveness of the Choizitaconso TPE program on community-validated outcomes, especially internalised stigma.

Mental Health Public Stigma in US Jewish Communities

Stigma is a multifaceted barrier for individuals living with mental illness, contributing to negative stereotypes, prejudice, and discrimination, and is underinvestigated in minority ethnic groups. This study examines the stigma within the US Jewish communities, specifically the following: a) differences in public stigma dimensions based on mental illness ( e.g. , major depressive disorder, anxiety disorder, schizophrenia, or alcohol use disorder) and sex; and b) whether participant characteristics influence the public stigma. A community-based sample of 317 self-identified Jewish individuals participated in an experimental randomized vignette survey on stigma and help-seeking beliefs toward various mental illness. Findings indicate differences in stigma based on stigmatized individuals' sex and diagnosis as well as participants' demographics. Schizophrenia and alcohol use disorder were stigmatized similarly, with lower stigma for depression and the least stigma toward anxiety. Of interest, younger males have the most treatability and professional efficacy stigma, and tailored stigma-reducing interventions are recommended.

Alcohol use disorder and disability insurance in Switzerland: the attitudes and views of lawyers, insurance medical experts, and addiction-specialist therapists

BACKGROUND

According to a landmark decision by the Swiss Federal Supreme Court, people with a substance use disorder (SUD) are now eligible for disability benefits if their disorder impairs their ability to work. Alcohol use disorder (AUD) is one of the most common SUDs in Switzerland and is associated with high societal and economic costs. This study aimed to gain an in-depth understanding of the views of professional stakeholder groups regarding AUD and their opinions on the new legal precedent.

METHODS

Swiss social insurance lawyers, insurance medical experts, and addiction-specialist therapists (N = 79) answered an online questionnaire. Due to violations of the assumption of normality, non-parametric tests are reported in most cases.

RESULTS

Therapists held significantly higher regard for patients with AUD than both lawyers and insurance medical experts. All three groups strongly supported a disease view of AUD but agreed significantly less that it was a disease like cancer, suggesting that AUDs might be seen as at least partially self-inflicted. Overall, moralist views of AUD received considerably less support than the disease view, with lawyers agreeing with moralist views more than therapists. All groups were well-informed and largely supportive about the new legal precedent. When asked about stipulating participation in medical treatment to mitigate damages associated with a claim, attending therapy was supported the most amongst the groups (80% of participants felt this was somewhat or fully appropriate), followed by a reduction in drinking quantity (58%), and abstinence (18%). In all three groups, we identified associations between certain views and opinions on AUD and support for the new legal precedent.

CONCLUSIONS

Whilst there were differences between the stakeholder groups in their regard for and views of AUD, all three adopted a clear harm-reduction approach with respect to measures to mitigate damages associated with the insurance disability claim. A possible connection of this stance with the Swiss national drug policy in recent years is discussed together with limitations of the study and practical implications of the findings.

Alcohol-Associated Tissue Injury: Current Views on Pathophysiological Mechanisms

At-risk alcohol use is a major contributor to the global health care burden and leads to preventable deaths and diseases including alcohol addiction, alcoholic liver disease, cardiovascular disease, diabetes, traumatic injuries, gastrointestinal diseases, cancers, and fetal alcohol syndrome. Excessive and frequent alcohol consumption has increasingly been linked to alcohol-associated tissue injury and pathophysiology, which have significant adverse effects on multiple organ systems. Extensive research in animal and in vitro models has elucidated the salient mechanisms involved in alcohol-induced tissue and organ injury. In some cases, these pathophysiological mechanisms are shared across organ systems. The major alcohol- and alcohol metabolite-mediated mechanisms include oxidative stress, inflammation and immunometabolic dysregulation, gut leak and dysbiosis, cell death, extracellular matrix remodeling, endoplasmic reticulum stress, mitochondrial dysfunction, and epigenomic modifications. These mechanisms are complex and interrelated, and determining the interplay among them will make it possible to identify how they synergistically or additively interact to cause alcohol-mediated multiorgan injury. In this article, we review the current understanding of pathophysiological mechanisms involved in alcohol-induced tissue injury.

Improving internet-delivered cognitive behaviour therapy for alcohol misuse: Patient perspectives following program completion

Although Internet-delivered cognitive behaviour therapy (ICBT) for alcohol misuse is efficacious in research trials, it is not routinely available in practice. Moreover, there is considerable variability in engagement and outcomes of ICBT for alcohol misuse across studies. The Alcohol Change Course (ACC) is an ICBT program that is offered free of charge by an online clinic in Saskatchewan, Canada, which seeks to fill this service gap, while also conducting research to direct future improvements of ICBT. As there is limited qualitative patient-oriented research designed to improve ICBT for alcohol misuse, in this study, we describe patient perceptions of the ACC post-treatment. Specifically, post-treatment feedback was obtained from 191 of 312 patients who enrolled in the ACC. Qualitative thematic analysis was used to examine post-treatment written comments related to what patients liked and disliked about the course, which skills were most helpful for them, and their suggestions for future patients. The majority of patients endorsed being very satisfied or satisfied with the course (n = 133, 69.6%) and 94.2% (n = 180) perceived the course as being worth their time. Worksheets (n = 61, 31.9%) and reflections of others (n = 40, 20.9%) received the most praise. Coping with cravings (n = 63, 33.0%), and identifying and managing risky situations (n = 46, 24.1%) were reported as the most helpful skills. Several suggestions for refining the course were provided with the most frequent recommendation being a desire for increased personal interaction (n = 24, 12.6%) followed by a desire for wanting more information (n = 22, 11.5%). Many patients offered advice for future ACC patients, including suggestions to make a commitment (n = 47, 24.6%), do all of the work (n = 29, 15.2%), and keep a consistent approach to the course (n = 24, 12.6%). The results provide valuable patient-oriented directions for improving ICBT for alcohol misuse.

Stigmatization of people with alcohol use disorders: An updated systematic review of population studies

BACKGROUND

We summarize research on the public stigmatization of persons with alcohol use disorder (AUD) in comparison with other mental health conditions and embed the results into a conceptual framework of the stigma process.

METHODS

We conducted a systematic search using Embase, MEDLINE, PubMed and PsycINFO (via Ovid), and Web of Science for population-based studies on the public stigma in AUD and at least 1 other mental health condition, published between October 1, 2010 and December 20, 2020, thus including all studies published since the last systematic review on this topic. The study is registered with PROSPERO (registration number: CRD42020173054).

RESULTS

We identified 20,561 records, of which 24 met the inclusion criteria, reporting results from 16 unique studies conducted in 9 different countries. Compared to substance-unrelated mental disorders, persons with AUD were generally less likely to be considered mentally ill, while they were perceived as being more dangerous and responsible for their condition. Further, the public desire for social distance was consistently higher for people with AUD. We found no consistent differences in the public stigma toward persons with AUD in comparison with other substance use disorders.

CONCLUSION

The stigmatization of persons with AUD remains comparatively high and is distinct from that of other substance-unrelated disorders.

Continuum beliefs are associated with higher problem recognition than binary beliefs among harmful drinkers without addiction experience

Low problem recognition may be an important barrier to opportunities for self-change or help-seeking in harmful drinkers. Little is known about how the beliefs harmful drinkers hold about the nature and causes of alcohol problems affect problem recognition and subsequent behaviour change processes. Participants (n = 597) recruited online were randomised to one of two conditions designed to promote beliefs according to (a) a continuum model of alcohol problems or (b) a binary disease model, or (c) a control condition. Participants completed measures of alcohol problem beliefs, problem recognition and other indices including the Alcohol Use Disorder Identification Test (AUDIT), addiction beliefs, addiction experience and demographics. Results showed that harmful drinkers without addiction experience exposed to the continuum condition had significantly higher problem recognition than those in binary disease model or control conditions. Continuum beliefs appear to offer self-evaluative benefits for harmful drinkers with low alcohol problem recognition, thus potentially facilitating help-seeking or self-change regarding alcohol use. Further research to understand the mechanisms by which continuum beliefs may promote more accurate drinking self-evaluation and its potential for behaviour change is warranted. The role of continuum beliefs may have important consequences for alcohol-related messaging and interventions seeking to promote self-change or help-seeking.

Optimizing internet-delivered cognitive behaviour therapy for alcohol misuse: a study protocol for a randomized factorial trial examining the effects of a pre-treatment assessment interview and health educator guidance

BACKGROUND

Alcohol misuse is a common, disabling, and costly issue worldwide, but the vast majority of people with alcohol misuse never access treatment for varying reasons. Internet-delivered cognitive behaviour therapy (ICBT) may be an attractive treatment alternative for individuals with alcohol misuse who are reluctant to seek help due to stigma, or who live in rural communities with little access to face-to-face treatment. With the growing development of ICBT treatment clinics, investigating ways to optimize its delivery within routine clinic settings becomes a crucial avenue of research. Some studies in the alcohol treatment literature suggest that assessment interviews conducted pre-treatment may improve short- and long-term drinking outcomes but no experimental evaluation of this has been conducted. Further, research on internet interventions for alcohol misuse suggests that guidance from a therapist or coach improves outcomes, but more research on the benefits of guidance in ICBT is still needed.

METHODS

This study is a 2X2 factorial randomized controlled trial where all of the expected 300 participants receive access to the Alcohol Change Course, an eight-week ICBT program. A comprehensive pre-treatment assessment interview represents factor 1, and guidance from a health educator represents factor 2. All participants will be asked to respond to measures at screening, pre-treatment, mid-treatment, post-treatment and 3, 6 and 12 months after treatment completion.

DISCUSSION

This study will provide valuable information on optimization of ICBT for alcohol misuse within routine clinic settings.

Alcohol use disorders

Alcohol use disorders consist of disorders characterised by compulsive heavy alcohol use and loss of control over alcohol intake. Alcohol use disorders are some of the most prevalent mental disorders globally, especially in high-income and upper-middle-income countries; and are associated with high mortality and burden of disease, mainly due to medical consequences, such as liver cirrhosis or injury. Despite their high prevalence, alcohol use disorders are undertreated partly because of the high stigma associated with them, but also because of insufficient systematic screening in primary health care, although effective and cost-effective psychosocial and pharmacological interventions do exist. Primary health care should be responsible for most treatment, with routine screening for alcohol use, and the provision of a staggered treatment response, from brief advice to pharmacological treatment. Clinical interventions for these disorders should be embedded in a supportive environment, which can be bolstered by the creation of alcohol control policies aimed at reducing the overall level of consumption.

Facilitating Screening and Brief Interventions in Primary Care: A Systematic Review and Meta-Analysis of the AUDIT as an Indicator of Alcohol Use Disorders

Background

The Alcohol Use Disorders Identification Test (AUDIT) was developed for use in primary health care settings to identify hazardous and harmful patterns of alcohol consumption, and is often used to screen for alcohol use disorders (AUDs). This study examined the AUDIT as a screening tool for AUDs.

Methods

A systematic literature search was performed of electronic bibliographic databases (CINAHL, Embase, ERIC, MEDLINE, PsycINFO, Scopus, and Web of Science) without language or geographic restrictions for original quantitative studies published before September 1, 2018, that assess the AUDIT's ability to screen for AUDs. Random‐effects meta‐regression models were constructed by sex to assess the potential determinants of the AUDIT's specificity and sensitivity. From these models and ecological data from the Global Information System on Alcohol and Health, the true‐ and false‐positive and true‐ and false‐negative proportions were determined. The number of people needed to be screened to treat 1 individual with an AUD was estimated for all countries globally where AUD data exist, using a specificity of 0.95.

Results

A total of 36 studies met inclusion criteria for the meta‐regression. The AUDIT score cut‐point was significantly associated with sensitivity and specificity. Standard drink size was found to affect the sensitivity and specificity of the AUDIT for men, but not among women. The AUDIT performs less well in identifying women compared to men, and countries with a low prevalence of AUDs have higher false‐positive rates compared to countries with a higher AUD prevalence.

Conclusions

The AUDIT does not perform well as a screening tool for identifying individuals with an AUD, especially in countries and among populations with a low AUD prevalence (e.g., among women), and thus should not be used for this purpose.

Outcome Assessment in Trials of Pharmacological Treatments for Alcohol Use Disorders: Fair and Strict Testing

Outcome assessment in the pharmacological treatment of alcohol use disorders (AUDs) faces specific challenges resulting from low adherence to treatment, high rates of dropout, and the susceptibility of patient self-reports to bias. This review discusses methodological issues in planning, conducting, and interpreting clinical trials on AUD treatment against the background of the principle of 'strictness and fairness' of testing. Threats to fairness include factors that limit the implementation of an intervention, such as low compliance and early treatment termination. In turn, fairness of testing is increased by factors that support the degree to which an intervention is implemented, such as the use of adequate pretreatments and the matching of psychosocial and pharmacological treatment strategies. Furthermore, selecting outcomes on the basis of an intervention's mechanism of action and including continuous outcomes as sensitive measures of drinking change further increases fairness by increasing the likelihood that the data will adequately reflect the effects of the intervention. On the other hand, strictness of testing is increased by all measures that limit the influence of confounders that could potentially lead to an overestimation of effects. The use of a side effect-mimicking placebo to prevent an unmasking of blinding and the repeated assessment of alcohol biomarkers to validate drinking self-reports might be valid strategies to further increase the strictness of testing by limiting risks of bias in trials of AUD treatment.

Barriers to implement screening for alcohol consumption in Spanish hypertensive patients

BACKGROUND

Alcohol intake and hypertension (HT) are interrelated public health problems with cost-effective interventions at the primary care level that, to date, are poorly implemented.

OBJECTIVE

This study aims to explore the barriers to implementing alcohol interventions for people with HT in primary care.

METHODS

As part of the project BASIS (Baseline Alcohol Screening and Intervention Survey), an internet survey from five European countries was developed to determine the role of alcohol in the management of HT in primary care practice. The survey contained 28 core items and 7 country-specific items. We present answers from Spanish general practitioners (GPs), who were reached through the main professional and scientific societies via e-mail and asked to take the online survey.

RESULTS

In total, 867 GPs answered the survey (65.1% women, 70.4% > 30 years old). As indicated by the Alcohol Use Disorders Identification Test-C scores, 12.4% of GPs who responded were risky drinkers (21.3% of men versus 7.1% of women). GPs reported considering alcohol relatively unimportant in HT treatment, as well as a difficult condition to deal with. The three main barriers to implement screening for alcohol consumption in HT patients were the lack of time (50.0%), considering alcohol unimportant for HT (28.4%) and stigma (16.5%).

CONCLUSIONS

GPs did not consider alcohol consumption a relevant factor for HT and, additionally, found it difficult to deal with alcohol problems. Some of the barriers for alcohol screening could be overcome through structural changes in the health system, such as empowering GPs to treat alcohol use disorders (rather than a single focus on implementing preventive strategies) by enhancing training in alcohol diagnosis and treatment.

Selbststigmatisierung und soziale Integration bei Alkoholabhängigkeit

Zusammenfassung. Zielsetzung: Menschen mit Alkoholabhängigkeit werden im Vergleich zu Personen mit anderen psychischen Krankheiten besonders stark stigmatisiert. Selbststigmatisierung aufgrund der eigenen Alkoholabhängigkeit hat vielfältige soziale Folgen. Unter Anwendung von Corrigans progressivem Modell zur Selbststigmatisierung soll der Zusammenhang zwischen geringer sozialer Integration und Selbststigmatisierung bei Alkoholabhängigen näher untersucht werden. Methodik: Es wurden N = 86 Patienten mit Alkoholabhängigkeit interviewt. Dabei wurden ein objektives Maß zur sozialen Integration, eine Skala zur Selbststigmatisierung bei Menschen mit Alkoholabhängigkeit, eine Skala zur Erfassung der Schwere der Alkoholabhängigkeit und das Ausmaß an psychischer Belastung erfasst. Ergebnisse: Es zeigte sich ein signifikanter negativer Zusammenhang zwischen der Anwendung negativer Stereotype auf sich selbst und geringerer sozialer Integration, sowie zwischen dem Selbstwertverlust aufgrund der eigenen Alkoholabhängigkeit und der sozialer Integration. In allen Regressionsanalysen wurde für die konfundierenden Variablen psychische Belastung, Schwere der Alkoholerkrankung, Alter und Geschlecht kontrolliert. Schlussfolgerung: Selbststigmatisierung aufgrund der eigenen Alkoholabhängigkeit ist ein wichtiges Korrelat fehlender sozialer Integration oder sozialem Rückzug bei Menschen mit Alkoholabhängigkeit und sollte daher bei der psychotherapeutischen Behandlung berücksichtigt werden.

Similarities and Differences between Individuals Seeking Treatment for Gambling Problems vs. Alcohol and Substance Use Problems in Relation to the Progressive Model of Self-stigma

Aims: People with gambling as well as substance use problems who are exposed to public stigmatization may internalize and apply it to themselves through a mechanism known as self-stigma. This study implemented the Progressive Model for Self-Stigma which consists four sequential interrelated stages: awareness, agreement, application and harm on three groups of individuals with gambling, alcohol and other substance use problems. It explored whether the two guiding assumptions of this model (each stage is precondition for the following stage which are trickle-down in nature, and correlations between proximal stages should be larger than correlations between more distant stages) would differentiate people with gambling problems from those with alcohol and other substance use problems in terms of their patterns of self-stigma and in terms of the stages in the model. Method: 37 individuals with gambling problems, 60 with alcohol problems and 51 with drug problems who applied for treatment in rehabilitation centers in Israel in 2015-2016 were recruited. They completed the Self-stigma of Mental Illness Scale-Short Form which was adapted by changing the term "mental health" to gambling, alcohol or drugs, and the DSM-5-diagnostic criteria for gambling, alcohol or drug disorder. Results: The assumptions of the model were broadly confirmed: a repeated measures ANCOVA revealed that in all three groups there was a difference between first two stages (aware and agree) and the latter stages (apply and harm). In addition, the gambling group differed from the drug use and alcohol groups on the awareness stage: individuals with gambling problems were less likely to be aware of stigma than people with substance use or alcohol problems. Conclusion: The internalization of stigma among individuals with gambling problems tends to work in a similar way as for those with alcohol or drug problems. The differences between the gambling group and the alcohol and other substance groups at the aware stage may suggest that public stigma with regard to any given addictive disorder may be a function of the type of addiction (substance versus behavioral).

Quantifying the global contribution of alcohol consumption to cardiomyopathy

Background

The global impact of alcohol consumption on deaths due to cardiomyopathy (CM) has not been quantified to date, even though CM contains a subcategory for alcoholic CM with an effect of heavy drinking over time as the postulated underlying causal mechanism. In this feasibility study, a model to estimate the alcohol-attributable fraction (AAF) of CM deaths based on alcohol exposure measures is proposed.

Methods

A two-step model was developed based on aggregate-level data from 95 countries, including the most populous (data from 2013 or last available year). First, the crude mortality rate of alcoholic CM per 1,000,000 adults was predicted using a negative binomial regression based on prevalence of alcohol use disorders (AUD) and adult alcohol per capita consumption (APC) (n = 52 countries). Second, the proportion of alcoholic CM among all CM deaths (i.e., AAF) was predicted using a fractional response probit regression with alcoholic CM crude mortality rate (from Step 1), AUD prevalence, APC per drinker, and Global Burden of Disease region as predictions. Additional models repeated these steps by sex and for the wider Global Burden of Disease study definition of CM.

Results

There were strong correlations (>0.9) between the crude mortality rate of alcoholic CM and the AAFs, supporting the modeling strategy. In the first step, the population-weighted mean crude mortality rate was estimated at 8.4 alcoholic CM deaths per 1,000,000 (95% CI: 7.4–9.3). In the second step, the global AAFs were estimated at 6.9% (95% CI: 5.4–8.4%). Sex-specific figures suggested a lower AAF among females (2.9%, 95% CI: 2.3–3.4%) as compared to males (8.9%, 95% CI: 7.0–10.7%). Larger deviations between observed and predicted AAFs were found in Eastern Europe and Central Asia.

Conclusions

The model proposed promises to fill the gap to include AAFs for CM into comparative risk assessments in the future. These predictions likely will be underestimates because of the stigma involved in all fully alcohol-attributable conditions and subsequent problems in coding of alcoholic CM deaths.

Does calling alcoholism an illness make a difference? The public image of alcoholism in Italy

AIMS

Using data from a population survey in two communities in the region of Sardinia, Italy, we examined the association between illness definition and attribution of personal characteristics to people with alcoholism.

METHODS

Quota samples, stratified by gender and age, were drawn from the general population (males: 48%; mean age 48±18; range: 15-90). A fully-structured interview was conducted face-to-face with 404 respondents. The assessment of the public view of 'alcoholics' was measured by their reactions to stimulus words rated on bipolar scales, and defined with adjectives with opposite meanings at each end.

RESULTS

322 participants (80%) rated the 'alcoholic' as 'ill'. The definition of the 'alcoholic' as being ill showed a statistically higher odd of stigma across all the dimensions of personal attributes.

CONCLUSIONS

The expectation that people adopting the illness model would tend to blame less those afflicted for their condition and, consequently, stigmatize them less, was not confirmed.

How should prevalence of alcohol use disorders be assessed globally?

Alcohol is a major risk factor for global burden of disease, and alcohol use disorders make up a considerable portion of this burden. Up to now, prevalence of alcohol use disorders has been estimated based on general population surveys with the Composite International Diagnostic Interview (CIDI) as the gold standard for assessment. However, three major problems have been identified with the current conceptualization of alcohol use disorders and its measurement via CIDI: cultural specificity of key criteria measured such as loss of control; lack of convergence of diagnoses identified by CIDI with clinically relevant diagnoses in primary health care; and impact of stigma on measurement. As a solution, it is proposed to measure alcohol use disorders via heavy drinking over time, with thresholds taken from the European Medicines Agency (60 and more grams on average per day of pure alcohol for men, and 40+ grams for women). Current data on level of drinking (per capita consumption) assessed via taxation and other means allow for a measure of less bias. If these thresholds are considered too low and there is more emphasis on need for specialized treatment, then thresholds for very heavy drinking can be taken as alternatively (100+, and 60+ grams per day pure alcohol for men and women, respectively).

An online intervention using information on the mental health-mental illness continuum to reduce stigma

BACKGROUND

A core component of stigma is being set apart as a distinct, dichotomously different kind of person. We examine whether information on a continuum from mental health to mental illness reduces stigma.

METHOD

Online survey experiment in a quota sample matching the German population for age, gender and region (n=1679). Participants randomly received information on either (1) a continuum, (2) a strict dichotomy of mental health and mental illness, or (3) no information. We elicited continuity beliefs and stigma toward a person with schizophrenia or depression.

RESULTS

The continuum intervention decreased perceived difference by 0.19 standard deviations (SD, P<0.001) and increased social acceptance by 0.18 SD (P=0.003) compared to the no-text condition. These effects were partially mediated by continuity beliefs (proportion mediated, 25% and 26%), which increased by 0.19 SD (P<0.001). The dichotomy intervention, in turn, decreased continuity beliefs and increased notions of difference, but did not affect social acceptance.

CONCLUSION

Attitudes towards a person with mental illness can be improved by providing information on a mental health-mental illness continuum.
