Although structured psychological treatments are recommended as first-line interventions for harmful drinking, only a small fraction of people globally receive these treatments because of poor access in routine primary care. We assessed the effectiveness and cost-effectiveness of Counselling for Alcohol Problems (CAP), a brief psychological treatment delivered by lay counsellors to patients with harmful drinking attending routine primary health-care settings. In this randomised controlled trial, we recruited male harmful drinkers defined by an Alcohol Use Disorders Identification Test (AUDIT) score of 12–19 who were aged 18–65 years from ten primary health centres in Goa, India. We excluded patients who needed emergency medical treatment or inpatient admission, who were unable to communicate clearly, and who were intoxicated at the time of screening. Participants were randomly allocated (1:1) by trained health assistants based at the primary health centres to enhanced usual care (EUC) alone or EUC combined with CAP, in randomly sized blocks of four to six, stratified by primary health centre, and allocation was concealed with use of sequential numbered opaque envelopes. Physicians providing EUC and those assessing outcomes were masked. Primary outcomes were remission (AUDIT score of <8) and mean daily alcohol consumed in the past 14 days, at 3 months. Secondary outcomes were the effect of drinking, disability score, days unable to work, suicide attempts, intimate partner violence, and resource use and costs of illness. Analyses were on an intention-to-treat basis. We used logistic regression analysis for remission and zero-inflated negative binomial regression analysis for alcohol consumption. We assessed serious adverse events in the per-protocol population. This trial is registered with the ISCRTN registry, number ISRCTN76465238. Between Oct 28, 2013, and July 29, 2015, we enrolled and randomly allocated 377 participants (188 [50%] to the EUC plus CAP group and 190 [50%] to the EUC alone group [one of whom was subsequently excluded because of a protocol violation]), of whom 336 (89%) completed the 3 month primary outcome assessment (164 [87%] in the EUC plus CAP group and 172 [91%] in the EUC alone group). The proportion with remission (59 [36%] of 164 in the EUC plus CAP group vs 44 [26%] of 172 in the EUC alone group; adjusted prevalence ratio 1·50 [95% CI 1·09–2·07]; p=0·01) and the proportion abstinent in the past 14 days (68 [42%] vs 31 [18%]; adjusted odds ratio 3·00 [1·76–5·13]; p<0·0001) were significantly higher in the EUC plus CAP group than in the EUC alone group, but we noted no effect on mean daily alcohol consumed in the past 14 days among those who reported drinking in this period (37·0 g [SD 44·2] vs 31·0 g [27·8]; count ratio 1·08 [0·79–1·49]; p=0·62). We noted an effect on the percentage of days abstinent in the past 14 days (adjusted mean difference [AMD] 16·0% [8·1–24·1]; p<0·0001), but no effect on the percentage of days of heavy drinking (AMD −0·4% [–5·7 to 4·9]; p=0·88), the effect of drinking (Short Inventory of Problems score AMD–0·03 [–1·93 to 1·86]; p=0.97), disability score (WHO Disability Assessment Schedule score AMD 0·62 [–0·62 to 1·87]; p=0·32), days unable to work (no days unable to work adjusted odds ratio 1·02 [0·61–1·69]; p=0.95), suicide attempts (adjusted prevalence ratio 1·8 [–2·4 to 6·0]; p=0·25), and intimate partner violence (adjusted prevalence ratio 3·0 [–10·4 to 4·4]; p=0·57). The incremental cost per additional remission was $217 (95% CI 50–1073), with an 85% chance of being cost-effective in the study setting. We noted no significant difference in the number of serious adverse events between the two groups (six [4%] in the EUC plus CAP group vs 13 [8%] in the EUC alone group; p=0·11). CAP delivered by lay counsellors plus EUC was better than EUC alone was for harmful drinkers in routine primary health-care settings, and might be cost-effective. CAP could be a key strategy to reduce the treatment gap for alcohol use disorders, one of the leading causes of the global burden among men worldwide. Wellcome Trust.

Maladaptive reward memories (MRMs) are involved in the development and maintenance of acquired overconsumption disorders, such as harmful alcohol and drug use. The process of memory reconsolidation - where stored memories become briefly labile upon retrieval - may offer a means to disrupt MRMs and prevent relapse. However, reliable means for pharmacologically weakening MRMs in humans remain elusive. Here we demonstrate that the N-methyl D-aspartate (NMDA) antagonist ketamine is able to disrupt MRMs in hazardous drinkers when administered immediately after their retrieval. MRM retrieval + ketamine (RET + KET) effectively reduced the reinforcing effects of alcohol and long-term drinking levels, compared to ketamine or retrieval alone. Blood concentrations of ketamine and its metabolites during the critical ‘reconsolidation window’ predicted beneficial changes only following MRM reactivation. Pharmacological reconsolidation interference may provide a means to rapidly rewrite maladaptive memory and should be further pursued in alcohol and drug use disorders. Memories linking environmental cues to alcohol reward are involved in the development and maintenance of heavy drinking. Here, the authors show that a single dose of ketamine, given after retrieval of alcohol-reward memories, disrupts the reconsolidation of these memories and reduces drinking in humans.

Alcohol use contributes to over 3 million deaths annually. In Tanzania, there are no evidence-based culturally adapted interventions to address harmful alcohol use behaviors. Our hypothesis was that \"Punguza Pombe Kwa Afya Yako\" (PPKAY, Reduce Alcohol for your Health), a culturally adapted brief intervention with text-based boosters, is superior to usual care in reducing binge drinking at 3 months post discharge. This manuscript reports. Stage 1 of our adaptive clinical trial which seeks to determine the effectiveness of the PPKAY+ booster to usual care; a subsequent stage will compare the PPKAY only to personalized and standard boosters. Adults who sought care for an acute injury at the Kilimanjaro Christian Medical Centre Emergency Department, self-disclosed alcohol use prior to the injury, scored ≥8 on the Alcohol Use Disorder Identification Test, and/or test positive by alcohol breathalyzer were offered enrollment. Participants were randomly assigned to PPKAY+ boosters (personalized or standard) or usual care at 1:1:1 allocation. Primary analyses followed the intention-to-treat principle. The PPKAY is a 15-min nurse delivered brief intervention using motivational interviewing techniques combined with a standardized or personalized text based reminder sent weekly to participants after hospital discharge and until 1 year post enrollment compared to a usual care arm. Follow-up was performed by blinded outcome assessors. Our pooled intervention arms PPKAY+ boosters were compared to usual care to determine the effectiveness of the intervention in reducing the number of binge drinking days, the trial's primary outcome, in the previous 4 weeks at 3 months after discharge. A total of 1,484 patients were screened for eligibility between October 12th 2020, and on April 14th 2023. 448 patients met inclusion criteria and consented to participate. 148 were randomized to usual care, and 300 to the pooled intervention arm. Reasons for attrition included loss to follow-up (n = 69), withdrawal (n = 6), and deaths (n = 4), with no differences between arms. Most participants were male (94%), from the Chagga tribe (59%) and had an average age of 36.4 years (SD 12.6) at baseline. At the 3-month follow-up, the intervention arm showed a notable reduction in mean predicted binge drinking days by 1.2 days (95% CI: [-2.3, -0.3]; p = 0.002) compared to the usual care group in a difference-in-differences analysis. Importantly, the self-reported nature of our primary outcome introduces the potential for social desirability bias, particularly in the absence of participant blinding, and should be considered a limitation when interpreting the findings. The reduction in binge drinking behavior at 3-month follow-up compared to usual care suggests our culturally adapted intervention is an effective alcohol intervention for patients acutely injured in Tanzania. According to the adaptive study design, the next phases of the trial will continue to compare the intervention arm with a paired down version without the text messages boosters.

Alcohol misuse ranks within the top ten health conditions with the highest global burden of disease. Low-intensity, Internet interventions for curbing adult alcohol misuse have been shown effective. Few meta-analyses have been carried out, however, and they have involved small numbers of studies, lacked indicators of drinking within low risk guidelines, and examined the effectiveness of unguided self-help only. We therefore conducted a more thorough meta-analysis that included both guided and unguided interventions. Systematic literature searches were performed up to September 2013. Primary outcome was the mean level of alcohol consumption and drinking within low risk guidelines for alcohol consumption at post-treatment. We selected 16 randomised controlled trials (with 23 comparisons and 5,612 participants) for inclusion. Results, showed a small but significant overall effect size in favour of Internet interventions (g = 0.20, 95% CI: 0.13-0.27, p<.001). Participants in Internet interventions drunk on average 22 grams of ethanol less than controls and were significantly more likely to be adhering to low-risk drinking guidelines at post-treatment (RD 0.13, 95% CI: 0.09-0.17, p<.001). Subgroup analyses revealed no significant differences in potential moderators for the outcome of alcohol consumption, although there was a near-significant difference between comparisons with waitlist control and those with assessment-only or alcohol information control conditions (p = .056). Internet interventions are effective in reducing adult alcohol consumption and inducing alcohol users to adhere to guidelines for low-risk drinking. This effect is small but from a public health point of view this may warrant large scale implementation at low cost of Internet interventions for adult alcohol misuse. Moderator analyses with sufficient power are, however, needed in order to assess the robustness of these overall results and to assess whether these interventions may impact on subgroups with different levels of success.

AbstractObjectiveTo evaluate the effectiveness of a doctor delivered screening and ultra-brief intervention (<1 minute) compared with simplified assessment only for reducing alcohol intake among patients with hazardous drinking in primary care.DesignPragmatic cluster randomised controlled trial.Setting40 primary care clinics in Japan that did not provide routine screening and brief intervention for hazardous drinking or treatment or self-help groups for alcohol dependency.Participants1133 outpatients aged 20-74 years with hazardous drinking (AUDIT-C (alcohol use disorders identification test-consumption) scores ≥5 for men and ≥4 for women). Clinic clusters were allocated to a study arm using a computer generated random sequence. Participants and staff who collected participant reported outcomes remained blinded to assignment.InterventionsPrimary care clinics were randomised to ultra-brief intervention (21 clinics, 531 patients) or simplified assessment only (19 clinics, 602 patients) groups. The intervention group comprised screening with AUDIT-C followed by brief oral advice and an alcohol information leaflet delivered in <1 minute. The control group comprised simplified assessment with AUDIT-C only.Main outcome measuresThe primary outcome was total alcohol consumption in the four weeks preceding the 24 week follow-up. Secondary outcomes included total alcohol consumption in the four weeks preceding the 12 week follow-up, and readiness to change drinking behaviour, measured at 12 and 24 weeks.ResultsAt 24 weeks, the difference in total alcohol consumption between the ultra-brief intervention group (1046.9 g/4 weeks (g/4wk), 95% confidence interval (CI) 918.3 to 1175.4) and control group (1019.0 g/4wk, 893.5 to 1144.6) was 27.8 g/4wk (−149.7 to 205.4, P=0.75), with a Hedges’ g of 0.02 (95% CI −0.10 to 0.14). At 12 weeks, the difference in total alcohol consumption between the intervention group (1034.1 g/4wk, 919.6 to 1148.7) and control group (979.3 g/4wk, 866.1 to 1092.4) was 54.9 g/4wk (−104.1 to 213.9, P=0.49), with a Hedges’ g of 0.04 (−0.08 to 0.16).ConclusionThis trial found no evidence to support the effectiveness of a doctor delivered ultra-brief intervention for hazardous drinking compared with simplified assessment only in primary care in Japan.Trial registrationUMIN Clinical Trials Registry UMIN000051388.

There is a strong association between alcohol use disorder (AUD) and intimate partner violence (IPV), both widely prevalent global health issues. However, few interventions target both IPV and AUD, include both partners in the intervention, and are delivered by non-specialist providers in low- and middle-income country (LMIC) settings with scarce mental health resources. This paper describes the protocol for a randomized controlled trial of a combined motivational interviewing (MI) and behavioral couples therapy (BCT) intervention delivered in urban primary care settings in India by nurses with no behavioral health training prior to joining the study. A total of 400 couples will be enrolled and randomized to one of two arms: an intervention arm comprised of 10, hour-long sessions of the MI + BCT intervention, and a control arm receiving enhanced usual care and medical-legal referrals. Data collection will take place at five timepoints: baseline (pre-intervention), three-, six-, nine-, and 12-month follow-ups. Primary quantitative outcomes include the frequency of intimate partner violence over the last 6 months and self-reported quantity and frequency of alcohol use, drinking behaviors, and alcohol-related problems as assessed on the Alcohol Use Disorders Identification Test (AUDIT). Secondary outcomes include number of days with a negative breathalyzer test over a one-week period, communication patterns, and the quality of marital relationship. Qualitative interviews with a sub-sample (n = 40 couples) from the intervention arm will take place immediately post-intervention and at 12 months to explore underlying mechanisms of change. If successful, study results can inform future efforts to develop scalable interventions for IPV and AUD that can be sustained in the Indian public health system through existing PHC staff and infrastructure and be adapted to similar sociocultural settings.

Counselling for Alcohol Problems (CAP), a brief intervention delivered by lay counsellors, enhanced remission and abstinence over 3 months among male primary care attendees with harmful drinking in a setting in India. We evaluated the sustainability of the effects after treatment termination, the cost-effectiveness of CAP over 12 months, and the effects of the hypothesized mediator 'readiness to change' on clinical outcomes. Male primary care attendees aged 18-65 years screening with harmful drinking on the Alcohol Use Disorders Identification Test (AUDIT) were randomised to either CAP plus enhanced usual care (EUC) (n = 188) or EUC alone (n = 189), of whom 89% completed assessments at 3 months, and 84% at 12 months. Primary outcomes were remission and mean standard ethanol consumed in the past 14 days, and the proposed mediating variable was readiness to change at 3 months. CAP participants maintained the gains they showed at the end of treatment through the 12-month follow-up, with the proportion with remission (AUDIT score < 8: 54.3% versus 31.9%; adjusted prevalence ratio [aPR] 1.71 [95% CI 1.32, 2.22]; p < 0.001) and abstinence in the past 14 days (45.1% versus 26.4%; adjusted odds ratio 1.92 [95% CI 1.19, 3.10]; p = 0.008) being significantly higher in the CAP plus EUC arm than in the EUC alone arm. CAP participants also fared better on secondary outcomes including recovery (AUDIT score < 8 at 3 and 12 months: 27.4% versus 15.1%; aPR 1.90 [95% CI 1.21, 3.00]; p = 0.006) and percent of days abstinent (mean percent [SD] 71.0% [38.2] versus 55.0% [39.8]; adjusted mean difference 16.1 [95% CI 7.1, 25.0]; p = 0.001). The intervention effect for remission was higher at 12 months than at 3 months (aPR 1.50 [95% CI 1.09, 2.07]). There was no evidence of an intervention effect on Patient Health Questionnaire 9 score, suicidal behaviour, percentage of days of heavy drinking, Short Inventory of Problems score, WHO Disability Assessment Schedule 2.0 score, days unable to work, or perpetration of intimate partner violence. Economic analyses indicated that CAP plus EUC was dominant over EUC alone, with lower costs and better outcomes; uncertainty analysis showed a 99% chance of CAP being cost-effective per remission achieved from a health system perspective, using a willingness to pay threshold equivalent to 1 month's wages for an unskilled manual worker in Goa. Readiness to change level at 3 months mediated the effect of CAP on mean standard ethanol consumption at 12 months (indirect effect -6.014 [95% CI -13.99, -0.046]). Serious adverse events were infrequent, and prevalence was similar by arm. The methodological limitations of this trial are the susceptibility of self-reported drinking to social desirability bias, the modest participation rates of eligible patients, and the examination of mediation effects of only 1 mediator and in only half of our sample. CAP's superiority over EUC at the end of treatment was largely stable over time and was mediated by readiness to change. CAP provides better outcomes at lower costs from a societal perspective.

Our aim was to evaluate intervention components of an alcohol reduction app: Drink Less. Excessive drinkers (AUDIT> =8) were recruited to test enhanced versus minimal (reduced functionality) versions of five app modules in a 2 5 factorial trial. Modules were: Self-monitoring and Feedback, Action Planning, Identity Change, Normative Feedback, and Cognitive Bias Re-training. Outcome measures were: change in weekly alcohol consumption (primary); full AUDIT score, app usage, app usability (secondary). Main effects and two-way interactions were assessed by ANOVA using intention-to-treat. A total of 672 study participants were included. There were no significant main effects of the intervention modules on change in weekly alcohol consumption or AUDIT score. There were two-way interactions between enhanced Normative Feedback and Cognitive Bias Re-training on weekly alcohol consumption (F = 4.68, p = 0.03) and between enhanced Self-monitoring and Feedback and Action Planning on AUDIT score (F = 5.82, p = 0.02). Enhanced Self-monitoring and Feedback was used significantly more often and rated significantly more positively for helpfulness, satisfaction and recommendation to others than the minimal version. To conclude, in an evaluation of the Drink Less smartphone application, the combination of enhanced Normative Feedback and Cognitive Bias Re-training and enhanced Self-monitoring and Feedback and Action Planning yielded improvements in alcohol-related outcomes after 4-weeks.

Background Alcohol abuse leads to numerous physical and mental health issues, as well as an increased risk of infectious and chronic diseases. Additionally, it contributes significantly to mortality and disability rates within the population. This study aims to assess the effectiveness of an educational intervention based on self-regulation theory (SRT) in reducing alcohol consumption among Iranian adolescents. Methods This analysis was conducted as a before-and-after experimental study involving 430 high school students in the southern Kerman province from 2023 to 2024. The study employed a cluster sampling approach, encompassing 14 educational classes, with seven classes randomly assigned to the intervention group and seven classes to the control group. Data were collected using a researcher-made questionnaire based on SRT, and its validity (with a CVR and CVI above 90%) and reliability (with a Cronbach’s alpha coefficient of more than 0.9 for the entire questionnaire) were rigorously assessed and confirmed. The data were analyzed using SPSS version 21, applying independent t-tests, paired t-tests, and chi-square tests. A p-value of less than 0.05 was considered statistically significant. Results The mean age of the adolescents was 15.32 ± 0.8 years. In intervention group, the mean score of the behavioral inhibition and working memory increased from 34.43 ± 7.83 and 31.59 ± 5.20 before the intervention to 37.33 ± 7.69 and 32.67 ± 5.83 after the intervention. Also, the mean score of internalization of speech, motivational evaluation system and behavioral reconstitution increased respectively from 30.37 ± 6.27, 24.88 ± 4.80 and 45.29 ± 6.30 before the intervention to 32.42 ± 6.14, 26.74 ± 4.70 and after the intervention. Following the educational intervention, the average scores for the constructs of behavioral inhibition ( p  = 0.03), working memory ( p  = 0.001), internalization of speech ( p  = 0.02), motivational evaluation system ( p  = 0.04), and behavioral reconstitution ( p  = 0.001) demonstrated a significant increase in the intervention group compared to the control group. Conclusions Interventions based on SRT can significantly decrease the likelihood of alcohol use among adolescents. Continuous training rooted in this theory within school settings is beneficial for preventing risky behaviors in adolescents.

Background The ubiquity of Internet connectivity, and widespread unmet needs, requires investigations of digital interventions for people seeking help with their drinking. The objective of this study was to test the effectiveness of a digital alcohol intervention compared to existing online resources for help seekers. Methods This parallel randomised controlled trial included 2129 risky drinkers with access to a mobile phone and aged 18 years or older. Randomised sub-studies investigated consent procedures and control group design. Simple computerised randomisation was used. Participants were aware of allocation after randomisation; research personnel were not. The digital intervention was designed around weekly monitoring of alcohol consumption followed by feedback and tools for behaviour change. Primary outcomes were total weekly consumption (TWC) and frequency of heavy episodic drinking (HED), measured 2 and 4 months post-randomisation. Results Between 25/04/2019 and 26/11/2020, 2129 participants were randomised (intervention: 1063, control: 1066). Negative binomial regression was used to contrast groups, with both Bayesian and maximum likelihood inference. The posterior median incidence rate ratio (IRR) of TWC was 0.89 (95% CI = 0.81;0.99, 98.2% probability of effect, P -value = 0.033) at 2 months among 1557 participants and 0.77 (95% CI = 0.69;0.86, > 99.9% probability of effect, P -value < 0.001) at 4 months among 1429 participants. For HED, the IRR was 0.83 (95% CI = 0.75;0.93, > 99.9% probability of effect, P -value = 0.0009) at 2 months among 1548 participants and 0.71 (95% CI = 0.63;0.79, probability of effect > 99.9%, P -value < 0.0001) at 4 months among 1424 participants. Analyses with imputed data were not markedly different. Conclusions A digital alcohol intervention produced self-reported behaviour change among online help seekers in the general population. The internal and external validity of this trial is strong, subject to carefully considered study limitations arguably inherent to trials of this nature. Limitations include higher than anticipated attrition to follow-up and lack of blinding. Trial registration The trial was prospectively registered ( ISRCTN48317451 ).
