Motivation to reduce alcohol consumption and subsequent attempts at reduction and changes in consumption in increasing and higher-risk drinkers in England: a prospective population survey

Psychological distress, tobacco smoking and alcohol use: A population survey in Great Britain

Aims

Psychological distress, smoking and alcohol use are interconnected. This study explores how distress and smoking independently, and in combination, are associated with alcohol consumption, past attempts and motivation to restrict alcohol use among people in Great Britain.

Methods

Pooled cross-sectional data of people (aged ≥ 16) in Great Britain (N = 87326) collected monthly from April 2020 to June 2023 in the nationally representative Smoking and Alcohol Toolkit Study. Multinomial and binary logistic regressions assessed how past 30-day distress (Kessler Psychological Distress Scale) and smoking were associated with alcohol use risk level (AUDIT-C), past-year attempts to restrict alcohol use, and motivation to restrict alcohol use in three months, adjusting for sex, age, socioeconomic and geographic characteristics.Findings.The interaction between distress and smoking on alcohol use risk level was significant. At all distress levels, odds of using alcohol at increasing or high risk were higher among participants who smoked in the past or currently. Moderate or serious distress was associated with lower odds of using alcohol at increasing risk among participants who did not smoke. Higher distress was positively associated with past-year attempts to restrict alcohol use, while smoking in those reporting low-to-moderate distress was negatively associated with past-year attempts. Higher distress was positively associated with motivation to restrict alcohol use in three months.

Conclusions

Smoking currently or in the past was independently associated with increased odds of using alcohol at increasing- or high-risk levels. Among those not smoking, higher distress was associated with reduced odds of using alcohol at increasing risk.

The predictive value of participant subgroups in a temporary alcohol abstinence challenge: compliance with abstinence and changes in drinking behaviour

INTRODUCTION

Dividing participants of Temporary alcohol Abstinence Challenges (TACs) into subgroups can improve intervention effectiveness by identifying individuals who require extra support. In a previous study, participant subgroups were identified based on determinants of behaviour change, including drinking refusal self-efficacy, craving, and behavioural automaticity. However, the predictive value of these subgroups for TAC success remains unknown. This study examined their predictive value for (i) abstinence during a TAC and (ii) changes in drinking behaviour.

METHODS

Data were analysed from 1800 Dutch TAC participants who completed baseline and eight-month follow-up questionnaires. Binary logistic regression assessed the effect of subgroup on abstinence. Ordinal and binary logistic regressions within Generalized Estimating Equation models examined subgroup effects on drinking behaviour changes, including drinking frequency, glasses per drinking day, and excessive volumes.

RESULTS

TAC subgroups differed in abstinence and in changes in drinking frequency and glasses per drinking day on weekdays. 'Habitual drinkers with perceived control to refuse' and 'drinkers in control' were more likely to abstain during the challenge than 'ordinary drinkers', whereas 'drinkers not in control' were less likely to abstain. 'Drinkers in control' showed smaller reductions in drinking frequency and glasses per drinking day on weekdays compared with 'ordinary drinkers'. No significant differences were found in changes in excessive drinking volumes and glasses per drinking day on weekends.

CONCLUSIONS

This study demonstrated the predictive value of subgroups for abstinence but found limited predictive value for changes in drinking behaviour after the challenge. Future research could explore personalized support to optimize behaviour change.

Development and evaluation of a free e-learning program on dementia risk reduction for the general public: A pre-post study

BACKGROUND

There is consistent evidence for the contribution of modifiable risk factors to dementia risk, offering opportunities for primary prevention. Yet, most individuals are unaware of these opportunities.

OBJECTIVE

To investigate whether online education about dementia risk reduction may be a low-level means to increase knowledge and support self-management of modifiable dementia risk factors.

METHODS

A pre-post study was conducted with Dutch community-dwelling individuals who registered for a free e-learning course called "Keep your brain healthy". The e-learning covers seven themes delivered week-by-week covering cognitive and physical activity, diet, and cardiovascular health, amongst others. Participants completed an online survey before starting the e-learning, immediately afterwards, and three months later. The survey covered user experience, knowledge on dementia risk reduction, motivation for, and engagement in, health behaviors.

RESULTS

Of the 477 participants (70.9% women, mean age = 63 years), 339 (71.1%) completed the survey immediately after the e-learning, and 241 (50.5%) completed the three-month follow-up survey. User experiences were positive with weekly themes receiving average ratings between 7.9-8.1 out of 10. Improvements over time were seen in knowledge of dementia risk reduction, Mediterranean diet adherence, social contact satisfaction, and motivation for physical activity. Cognitive activity levels and alcohol consumption improved over time in women. Moreover, improvements in knowledge and Mediterranean diet adherence remained present three months after course completion.

CONCLUSIONS

This e-learning program was positively perceived, increased knowledge of dementia risk reduction, and promoted engagement in brain-healthy lifestyles. The program can easily be implemented as a stand-alone tool or as part of larger dementia risk reduction initiatives.

Neurocognitive Markers during Maximum Alcohol Use in Late Adolescence as Predictors of Change in Later Drinking Behaviors

Background

The influence of alcohol use on later neurocognitive functioning is well researched, yet few studies have investigated whether neurocognition post-drinking initiation in adolescence predicts changes in later alcohol use.

Objective

Investigate neurocognitive task performance during maximum alcohol use in late adolescence as predictors of drinking behaviors 3-7 years later.

Methods

Analyses (n=105) were conducted on a longitudinal dataset involving adolescents (12-13 years-old) who were followed for 16 years. Time 1 (T1) was defined as the individuals' maximum drinking year within the first 10 study years and Time 2 (T2) was the first available data entry 3-7 years after T1. Four hierarchical linear regression models predicting follow-up alcohol use were estimated: drinking days, average drinks per drinking day, peak drinks, and binge episodes. All models included inhibition/cognitive flexibility, visuospatial ability, verbal memory, working memory, and their interactions with sex, while covarying for age at T1, follow-up duration and controlling for T1 drinking.

Results

Better visuospatial ability at T1 predicted decreases in later binge episodes at T2 (β= -.19, p= .048, partial r2 = .039). While better inhibition/cognitive flexibility at T1 predicted increases in follow-up drinks per drinking day at T2 (β= .18, p= .016, partial r2= .057).

Conclusion

Findings suggest specific neurocognitive abilities during maximum drinking in late adolescence are useful as predictors of change in later drinking quantity per occasion and could potentially inform intervention research targeting this age group.

Problem drinking among university students in Berlin

OBJECTIVE

Problem-drinking among university students is common and poses serious health-related risks. Therefore, identifying and addressing associated factors is important.

PARTICIPANTS AND METHODS

A large cross-sectional online-survey with 12,914 university students from Berlin was conducted from November 2016 to August 2017. Relative-risk- and correlation-analysis was used to identify factors associated with problem-drinking and regular heavy-drinking. Independent t-tests compared impulsivity and personality traits, chi-square-tests compared drinking motives between risk- and non-risk-drinkers.

RESULTS

Male gender, tobacco-smoking, illegal substance use, impulsivity and various sociodemographic and psychosocial variables were significantly related to problem/heavy-drinking. Extraversion was a risk, conscientiousness and agreeableness were protective factors. Drinking-motives did not differ significantly between risk- and non-risk-drinkers. Generally, the main drinking-motives were to feel elated, relax and social purposes.

CONCLUSION

The identified markers and related problem behaviors may serve as a tool to enhance the identification of student subgroups at risk for problem/heavy-drinking, and hence improve targeted health-intervention-programs.

Esketamine combined with a mindfulness-based intervention for individuals with alcohol problems

BACKGROUND

Alcohol use disorder (AUD) is a major public health issue, posing harmful consequences for individuals and society. Recent advances in addiction research have highlighted the therapeutic potential of ketamine-assisted therapy for AUD. However, the exact mechanisms underlying its effectiveness remain unknown.

AIMS

This double-blind, pilot study aimed to investigate esketamine combined with mindfulness-based intervention (MBI) to examine whether esketamine enhances engagement in MBI for individuals with alcohol misuse problems and whether enhanced engagement has any impact on alcohol-related outcomes.

METHODS

In all, 28 individuals with alcohol problems were randomly assigned to receive sublingual esketamine hydrochloride (AWKN002: 115.1 mg) or vitamin C (placebo) in an oral thin film and took part in 2 weeks of daily MBI. Participants were assessed on various self-report measures, including mindfulness, engagement in MBI (physical and psychological), alcohol cravings and consumption.

RESULTS

Esketamine enhanced psychological engagement with a daily MBI, compared to placebo, and led to transient decreases in alcohol cravings. Esketamine also resulted in significantly greater mystical experiences and dissociative states compared to placebo.

CONCLUSIONS

The findings suggest that esketamine may improve treatment outcomes when combined with mindfulness-based therapies through its ability to increase engagement with meditative practice.

ABC-training as a new intervention for hazardous alcohol drinking: Two proof-of-principle randomized pilot studies

BACKGROUND AND AIMS

ABC-training is a new intervention to encourage health behavior change that targets the automatic activation of adaptive beliefs (i.e. automatic inferences). The aim of this proof-of-principle study was to test the effectiveness of web-based ABC-training to change outcome expectancies of alcohol drinking in a sample of hazardous drinkers.

DESIGN

One exploratory and one confirmatory experiment with two between-subject conditions (online ABC- and control-training) and assessments at baseline and 1 week later (after three sessions of training).

SETTING

Participants recruited on Prolific Academic completed the web-based study.

PARTICIPANTS

Adults with self-reported hazardous alcohol drinking (Experiment 1: 193 adults, United Kingdom, age mean = 46.7 years; Experiment 2: 282 adults, different nationalities, age mean = 38.3 years).

INTERVENTION AND COMPARATOR

ABC-training involved completing an online task that required choosing personally relevant alternative behaviors to drinking alcohol in personally relevant antecedent contexts to attain personally important outcomes. Comparator was control-training, in which participants selected both the alternative behaviors and alcohol drinking an equal number of times. Training was completed at baseline, after 3 days and after 1 week.

MEASUREMENTS

Primary outcome was change in automatic and self-reported (negative/positive) outcome expectancies of alcohol drinking from baseline to after 1 week. Secondary outcomes were change in weekly alcohol consumption, self-efficacy, craving and motivation (and approach-alcohol associations in Experiment 1). Moderators were baseline outcome scores, motivation, age and alcohol dependency.

FINDINGS

Findings of this study are as follows: stronger increase in negative outcome expectancies after ABC- than control-training (Experiment 1: self-report, 95% confidence interval of difference scores (CIdiff ) = [0.04, Inf]; automatic, CIdiff  = [0.01, Inf]; Experiment 2: self-report, CIdiff  = [0.16, Inf]; automatic, CIdiff  = [0.002, Inf]). Stronger reduction in self-reported positive outcome expectancies after ABC- than control-training (Experiment 1: CIdiff  = [-Inf, -0.01]; Experiment 2: CIdiff  = [-Inf, -0.21]) but mixed findings on automatic positive outcome expectancies (Experiment 1: CIdiff  = [-Inf, 0.02]; Experiment 2: CIdiff  = [-Inf, -0.001]).

CONCLUSIONS

ABC-training may change outcome expectancies of alcohol consumption, but testing of clinically relevant effects in other samples is warranted.

Temporary abstinence challenges: What do we need to know?

Participation in temporary abstinence challenges (TAC) continues to increase with campaigns established in several countries. Temporarily abstaining from alcohol as part of such challenges is associated with ongoing benefits including reductions to alcohol consumption after the TAC. We identified three research priorities regarding TACs which are outlined in this paper. First, the role of temporary abstinence itself is unclear with post-TAC reductions in alcohol consumption still apparent among participants who do not remain fully abstinent throughout the challenge. It is necessary to establish to what degree temporary abstinence itself, rather than the combination of abstinence and the additional supports provided by TAC organisers (e.g., mobile applications, online support groups), contributes to changes in consumption after the TAC. Second, little is known about the psychological changes underlying these changes in alcohol consumption, with conflicting evidence as to whether increases in someone's belief in their ability to avoid drinking mediates the association between participation in a TAC and reductions in consumption afterwards. Other potential psychological and social mechanisms of change have been subjected to little, if any, scrutiny. Third, evidence of increased consumption post-TAC among a minority of participants indicates a need to establish for whom or in what circumstances participation in a TAC may result in unintended negative consequences. Focussing research in these areas would increase the confidence with which participation could be encouraged. It would also enable campaign messaging and additional supports to be prioritised and tailored to be as effective as possible in facilitating long-term change.

Attentional Bias to Alcohol Information: a Novel Dual-Probe Task

BACKGROUND

Even when motivated to consume less alcohol, attempts to do so are not always successful. Attentional bias to positive and negative alcohol-related information may play a role in shaping unintended drinking behaviour. The present exploratory study adapted a novel attentional bias task, to test whether selective attention to positive relative to negative information about alcohol consumption predicts mismatch between alcohol consumption intention and alcohol consumption behaviour.

METHOD

Thirty-five university students attempting to reduce their alcohol consumption participated in the study. Participants completed a novel attentional bias assessment task where two positive and negative audio-visual messages about alcohol consumption were simultaneously presented. At random intervals during these messages, two different probes were briefly and simultaneously presented, so that only one could be detected. Attention to positive vs. negative messages was inferred from the location of the probe recorded by the participant. Alcohol consumption in relation to participants' goals was measured using a real-time diary over the subsequent 7 days.

RESULTS

An attentional bias towards positive (relative to negative) messages about alcohol consumption predicted the degree to which participants consumed more alcohol than planned, but did not predict alcohol consumption itself.

CONCLUSION

This is the first study to our knowledge that has investigated the relationship between biased attention to alcohol-related information and variation in the success of intended reduction in alcohol consumption, and we suggest that it paves the way for further research into the role of attentional biases in health risk behaviours.

Integration of the Theory of Planned Behavior and Transtheoretical Model of Change for Prediction of Intentions to Reduce or Stop Alcohol Use among Thai Adolescents

Alcohol use among Thai adolescents has been increasing over the past few decades, and efforts to control consumption by underaged youth have proven largely ineffective. Objectives: This study tested components of the Theory of Planned Behavior (TPB) and Readiness to Change, based on the Transtheoretical Model (TTM), to identify useful constructs for developing alcohol use interventions for youth. Methods: A sample of 825 Thai student drinkers (65% female), between the ages of 14 and 19, were recruited in Bangkok, Thailand. Hierarchical regression analyses were used to test components of the TPB and Readiness to Change as predictors of intention to reduce/stop alcohol use while controlling for age, gender and alcohol use. Results: The model accounted for 58% of the variance of intentions. The TPB components accounted for a significant increase in variance beyond that explained by age, gender and alcohol use, ΔR² = .23, p < .001; Perceived Behavioral Control (PBC) was the strongest predictor (β =.41, p < .001), followed by Attitudes (β=.13, p < .001), and Subjective Norms (β =.09, p = .002). Readiness to Change composite scores (β=.54, p < .001) were added last and accounted for a further significant increase, ΔR² = .24, p < .001. Conclusions: The findings suggest that interventions should assess Readiness to Change and utilize effective processes in facilitating change at each stage. Other suggestions are to improve participants' PBC and to further examine the role of specific social norms and attitudes regarding perceived benefits and disadvantages of alcohol use.

Motivation to Quit Drinking in Individuals Coinfected with HIV and Hepatitis C

Alcohol consumption is common among individuals coinfected with HIV and hepatitis C (HCV) despite the uniquely harmful effects in this population. Limited research has examined factors that could influence drinking reduction or cessation among HIV/HCV coinfected persons; this study investigates motivation to quit. Participants were 110 alcohol-consuming HIV/HCV coinfected patients recruited from medical clinics. Participants self-reported 90-day drinking frequency and intensity; alcohol-related problems; reasons to quit drinking; reasons to drink; and motivation to quit drinking. Participants consumed alcohol on 54.1 (± 26.9) of the past 90 days. In a multivariate model that controlled for demographic variables, motivation to quit drinking was directly associated with alcohol-related problems (β_y·x = 0.35, p = .007) and reasons to quit drinking (β_y·x = 0.23, p = .021), and inversely associated with drinking for enhancement (β_y·x = - 0.36, p = .004). This study identified several factors associated with motivation to quit drinking in a sample of alcohol-consuming HIV/HCV patients.

A Qualitative Evaluation of the Acceptability of a Tailored Smartphone Alcohol Intervention for a Military Population: Information About Drinking for Ex-Serving Personnel (InDEx) App

Background

Alcohol consumption in the UK Armed Forces is higher than in the general population, and this pattern continues after leaving the service. Smartphone apps may be useful to increase ex-serving personnel’s awareness of their alcohol consumption, support self-monitoring, and prompt a change in behavior.

Objective

The study aimed to explore the acceptability of Information about Drinking in Ex-serving personnel (InDEx), a tailored smartphone app, combined with personalized short message service (SMS) text messaging designed to target ex-serving personnel who meet the criteria for hazardous alcohol use.

Methods

The InDEx intervention included 4 key modules: (1) assessment and normative feedback, (2) self-monitoring and feedback, (3) goal setting and review, and (4) personalized SMS text messaging. A semistructured telephone interview study was conducted with ex-serving personnel after using the app for a 28-day period. Interviews were used to explore the acceptability of app modules and its functionality and the perceived changes in participant’s drinking. Interview transcripts were analyzed using inductive thematic analysis.

Results

Overall, 94% (29/31) participants who used InDEx agreed to take part in a telephone interview. Overall, 4 themes were identified: Credibility, Meeting their needs, Simplicity, and Helpful for ex-serving personnel. The importance of credibility, functionality, and meeting the individual needs of ex-serving personnel was emphasized. Acceptability and engagement with specific modules of the app and text messages were influenced by the following: (1) if they felt it provided credible information, (2) whether the content was appropriately personalized to them, (3) the ease of use, and (4) beliefs about their own drinking behaviors. Participants recommended that the app would be most suitable for personnel about to leave the Armed Forces.

Conclusions

InDEx was an acceptable smartphone app for ex-serving personnel for monitoring alcohol consumption and in providing meaningful feedback to the individual. Pages that met the participant’s interests and provided real time personalized, credible feedback on their drinking and text messages tailored to participant’s interactions with the app were particularly favored.

Correlates of Reduced Alcohol Consumption among a Sample of Young Australians

AIMS

Population data suggest that a significant proportion of young drinkers are reducing or ceasing their alcohol use; however, there is a lack of information about the characteristics of young people who do so. Our study aimed to determine characteristics associated with self-reported attempted and successful alcohol reduction and cessation among young people in Victoria, Australia.

METHODS

Data are from a cross-sectional online survey with young people aged 15-29 years living in Victoria, Australia. Participants who reported consuming alcohol in the past 12 months were included in the analysis (N = 1,162).

RESULTS

Alcohol drinking cessation in the past 12 months was reported by 3.8% (n = 44) and reduced alcohol consumption was reported by 32.1% (n = 371) of participants. Characteristics associated with trying to reduce or cease alcohol consumption were older age, being born overseas, drinking at hazardous levels, experiencing alcohol-related harms and interest in health content on social media. Characteristics associated with successful alcohol reduction or cessation were being born overseas and experiencing alcohol-related harm, while being a member of a religious group was negatively associated.

CONCLUSIONS

Recent reduction in alcohol consumption was common among young people in this study. Recent reduction in alcohol consumption was common among young people in this study. A combination of factors appear to be correlated with recent attempts to reduce drinking young people including socio-demographic characteristics, religiosity, drinking practices and experience of harm, and interest in health.

Motivation to reduce alcohol consumption and subsequent attempts at reduction and changes in consumption in increasing and higher-risk drinkers in England: a prospective population survey

AIMS

To assess how far motivation to reduce alcohol consumption in increasing and higher-risk drinkers in England predicts self-reported attempts to reduce alcohol consumption and changes in alcohol intake during the following 6 months.

METHODS

This study used self-reported data from 2928 higher-risk drinkers in the Alcohol Toolkit Study (ATS): a series of monthly cross-sectional household surveys of adults aged 16+ years of age in England. Alcohol consumption was measured in an initial survey and in a 6-month telephone follow-up interview using the Alcohol Use Disorders Identification Test (AUDIT)-C questionnaire. Motivation was measured in the initial survey using the Motivation to Reduce Alcohol Consumption (MRAC) scale. Attempts to reduce alcohol consumption during the past 6 months were recorded at follow-up. Data were analysed using repeated-measures difference-in-differences and logistic regression models.

RESULTS

Participants with higher initial motivation to reduce alcohol consumption were more likely to report that they had made an attempt to reduce consumption at follow-up [adjusted odds ratio (ORadj ) = 2.39, 95% confidence interval (CI) = 1.75-3.29]. There was an overall reduction in alcohol consumption between initial survey and follow-up (ORadj  = 0.72, 95% CI = 0.65-0.79), but there was insufficient evidence of an additional effect of motivation to reduce consumption on subsequent changes in alcohol consumption, with the difference-in-differences effect instead suggesting an average increase (ORadj  = 1.37, 95% CI = 1.00-1.88).

CONCLUSIONS

Increasing and higher-risk drinkers in England who report greater motivation to reduce their consumption are more likely to report making an attempt to reduce during the next 6 months, but this may not be associated with a reduction in alcohol consumption.
