Motivational interviewing for the prevention of alcohol misuse in young adults

Motivation to Abstain from Drinking as a Moderator of Associations Between Parent and Offspring Problem Drinking

OBJECTIVE

Motivational processes are key factors in the development and maintenance of problem drinking and include motivation to drink as well as motivation to abstain from drinking. Although motivation to drink has been widely studied, little research has considered motivation to abstain from drinking. The current study addresses this gap in research by exploring the role of motivation to abstain from drinking based on dispositional risk, fear of negative consequences, religious and family constraints, and indifference to alcohol in associations between mother and father problem drinking and the problem drinking of college students.

METHOD

Data were collected from 337 U.S. college students (77.2% female, 86% White) who reported on their exposure to mother and father problem drinking, their own problem drinking, and their motivation to abstain from drinking for several reasons.

RESULTS

Findings supported the protective role of motivation to abstain from drinking based on fear of negative consequences of drinking. Persons exposed to parental problem drinking who had low motivation to abstain from alcohol based on dispositional risk were vulnerable to the intergenerational transmission of problem drinking. In addition, motivation to abstain from drinking based religious or family constraints was associated with lower problem drinking regardless of exposure to parental problem drinking.

CONCLUSIONS

Conviction-related motivation may be a powerful motivation to abstain from drinking, including among persons at risk due to parental problem drinking.

A Brief Intervention With Instant Messaging or Regular Text Messaging Support in Reducing Alcohol Use: A Randomized Clinical Trial

Importance

Alcohol use is prevalent among university students. Mobile instant messaging apps could enhance the effectiveness of an alcohol brief intervention (ABI), but the evidence is scarce.

Objective

To evaluate the effectiveness of an ABI plus 3 months of mobile chat-based instant messaging support for alcohol reduction in university students at risk of alcohol use disorder.

Design, Setting, and Participants

In this randomized clinical trial, 772 students at risk of alcohol use disorder (Alcohol Use Disorders Identification Test [AUDIT] score ≥8) were recruited from 8 universities in Hong Kong between October 15, 2020, and May 12, 2022. Participants were randomly assigned 1:1 to either the intervention or control group.

Interventions

Both groups received the same ABI at baseline, which consisted of face-to-face or video conferencing with research nurses who delivered personalized feedback based on the participant's AUDIT risk level, along with a 12-page booklet describing the benefits of alcohol reduction and the harmful effects of alcohol on health and social well-being. The intervention group then received 3 months of chat-based instant messaging support on alcohol reduction guided by behavioral change techniques. The control group received 3 months of short message service (SMS) messaging on general health topics.

Main Outcomes and Measures

All outcomes were self-reported. The primary outcome was alcohol consumption in grams per week at 6 months of follow-up. By definition, 1 alcohol unit contains 10 g of pure alcohol. Secondary outcomes at the 6-month follow-up included changes in AUDIT score, weekly alcohol consumption, intention to drink in the next 30 days, drinking frequency and any binge or heavy drinking in the past 30 days, and self-efficacy of quitting drinking. The primary analysis followed the intention-to-treat principle, and linear regression (reported as unstandardized coefficient B) and logistic regression (reported as odds ratios) were used to compare the primary and secondary outcomes between the intervention and control groups.

Results

The study included 772 students (mean [SD] age, 21.1 [3.5] years; 395 females [51.2%]) who were randomly assigned to either the intervention (n = 386) or control (n = 386) group. In the intention-to-treat analysis, the intervention group had lower alcohol consumption in grams per week (B, -11.42 g [95% CI, -19.22 to -3.62 g]; P = .004), a lower AUDIT score (B, -1.19 [95% CI, -1.63 to -0.34]; P = .003), reduced weekly alcohol unit consumption (B, -1.14 [95% CI, -1.92 to -0.36]; P = .004), and less intention to drink (odds ratio, 0.66 [95% CI, 0.47 to 0.92]; P = .01) at the 6-month follow-up compared with the control group. In analyses adjusted for baseline characteristics, interacting at least once with the research nurse on the instant messaging application resulted in lower estimated alcohol consumption in grams per week (adjusted B, -17.87 g [95% CI, -32.55 to -3.20 g]; P = .01), lower weekly alcohol unit consumption (adjusted B, -1.79 [95% CI, -3.25 to -0.32]; P = .02), and a lower AUDIT score (adjusted B, -0.53 [95% CI, -1.87 to -0.44]; P = .01) at 6 months.

Conclusions and Relevance

Results of this randomized clinical trial indicate that mobile chat-based instant messaging support for alcohol reduction in addition to an ABI was effective in reducing alcohol consumption in university students in Hong Kong at risk of alcohol use disorder.

Self-efficacy, mindfulness, and perceived social support as resources to maintain the mental health of students in Switzerland's universities of applied sciences: a cross-sectional study

BACKGROUND

Switzerland's student population is at a particularly high risk of developing mental health disorders, creating a major challenge for Switzerland's higher education establishments. Research to date has primarily sought to identify the risk factors affecting students' mental health; however, their exposure to these factors is often unavoidable. Thus, the present study adopted a salutogenic approach focussing on the determinants of health. We examined the mental health resources available to students reported in the literature as being susceptible to helping them maintain good mental health despite their exposure to risk factors.

METHODS

In February 2020, 2,415 first- and second-year bachelor's degree students in applied sciences in French-speaking Switzerland completed an online questionnaire. The variables measured were self-evaluated mental health, perceived stress and three potential health resources: students' feelings of self-efficacy, their capacity for mindfulness and their social support. The results were analysed using hierarchical linear regression models.

RESULTS

When all the variables were included in the model without interaction effect, our results revealed that students' self-evaluated mental health was negatively associated with perceived stress (β = -0.43, p < 0.001) and positively associated with the three potential health resources (self-efficacy: β = 0.26, p < 0.001; mindfulness: β = 0.10, p < 0.001; social support: β = 0.17, p < 0.001). An analysis of the interaction effects also revealed that a high level of self-efficacy was associated with perceived stress being less strongly linked to mental health (β = 0.29, p < 0.001).

CONCLUSIONS

These findings suggest that self-efficacy, mindfulness, and perceived social support are valuable resources for protecting students' mental health. Thus, implementing interventions aimed at reinforcing them, could support students in applied sciences all along their academic pathway, in their classes and during their professional work experience placements.

A prevention program for binge drinking among students based on mindfulness and implementation intention (ALCOMEDIIT): a randomized controlled trial

BACKGROUND

The emergence of new problematic alcohol consumption practices among young people requires new dynamics in prevention strategies. In this context, the ADUC project (Alcohol and Drugs at the University of Caen) aims to develop a better understanding of alcohol consumption, and in particular the practice of binge drinking (BD) in students, in order to develop relevant and adapted prevention tools. The ALCOMEDIIT study (Rin Normandie and IRESP funding; Agreement 20II31-00 - ADUC part 3) is a randomized controlled trial that focuses on the specific determinant of impulsivity. The main objective of this experiment is to assess a program for the prevention of BD practices based on motivational interviewing (MI) associated with implementation intention (II) and mindfulness meditation (MBM) in a student environment.

METHODS

This study will include 170 healthy subjects who will be students at the university, alcohol users, with a BD score > 1 in the month preceding the inclusion but not presenting any specific disorder. The trial will be proposed by e-mail and students who meet the inclusion criteria will join either a control group which will benefit from a MI or an experimental group which will additionally benefit from an initiation to MBM with II (initial visit T0). In order to measure the effectiveness of the prevention program in terms of BD decrease, a follow-up at 1 month (T1) as well as a follow-up at 6 months (T6; exploratory) will be proposed to all participants. The total duration of this research protocol is 21 months.

DISCUSSION

The purpose of this study is to evaluate the interest of associating mindfulness meditation practices and implementation of self-regulation strategies to optimize their use, with a motivational interview in an innovative prevention program aiming at reducing alcohol use and BD practice in the student population.

Motivational interviewing for substance use reduction

BACKGROUND

Substance use is a global issue, with around 30 to 35 million individuals estimated to have a substance-use disorder. Motivational interviewing (MI) is a client-centred method that aims to strengthen a person's motivation and commitment to a specific goal by exploring their reasons for change and resolving ambivalence, in an atmosphere of acceptance and compassion. This review updates the 2011 version by Smedslund and colleagues.

OBJECTIVES

To assess the effectiveness of motivational interviewing for substance use on the extent of substance use, readiness to change, and retention in treatment.

SEARCH METHODS

We searched 18 electronic databases, six websites, four mailing lists, and the reference lists of included studies and reviews. The last search dates were in February 2021 and November 2022.

SELECTION CRITERIA

We included randomised controlled trials with individuals using drugs, alcohol, or both. Interventions were MI or motivational enhancement therapy (MET), delivered individually and face to face. Eligible control interventions were no intervention, treatment as usual, assessment and feedback, or other active intervention.

DATA COLLECTION AND ANALYSIS

We used standard methodological procedures expected by Cochrane, and assessed the certainty of evidence with GRADE. We conducted meta-analyses for the three outcomes (extent of substance use, readiness to change, retention in treatment) at four time points (post-intervention, short-, medium-, and long-term follow-up).

MAIN RESULTS

We included 93 studies with 22,776 participants. MI was delivered in one to nine sessions. Session durations varied, from as little as 10 minutes to as long as 148 minutes per session, across included studies. Study settings included inpatient and outpatient clinics, universities, army recruitment centres, veterans' health centres, and prisons. We judged 69 studies to be at high risk of bias in at least one domain and 24 studies to be at low or unclear risk. Comparing MI to no intervention revealed a small to moderate effect of MI in substance use post-intervention (standardised mean difference (SMD) 0.48, 95% confidence interval (CI) 0.07 to 0.89; I2 = 75%; 6 studies, 471 participants; low-certainty evidence). The effect was weaker at short-term follow-up (SMD 0.20, 95% CI 0.12 to 0.28; 19 studies, 3351 participants; very low-certainty evidence). This comparison revealed a difference in favour of MI at medium-term follow-up (SMD 0.12, 95% CI 0.05 to 0.20; 16 studies, 3137 participants; low-certainty evidence) and no difference at long-term follow-up (SMD 0.12, 95% CI -0.00 to 0.25; 9 studies, 1525 participants; very low-certainty evidence). There was no difference in readiness to change (SMD 0.05, 95% CI -0.11 to 0.22; 5 studies, 1495 participants; very low-certainty evidence). Retention in treatment was slightly higher with MI (SMD 0.26, 95% CI -0.00 to 0.52; 2 studies, 427 participants; very low-certainty evidence). Comparing MI to treatment as usual revealed a very small negative effect in substance use post-intervention (SMD -0.14, 95% CI -0.27 to -0.02; 5 studies, 976 participants; very low-certainty evidence). There was no difference at short-term follow-up (SMD 0.07, 95% CI -0.03 to 0.17; 14 studies, 3066 participants), a very small benefit of MI at medium-term follow-up (SMD 0.12, 95% CI 0.02 to 0.22; 9 studies, 1624 participants), and no difference at long-term follow-up (SMD 0.06, 95% CI -0.05 to 0.17; 8 studies, 1449 participants), all with low-certainty evidence. There was no difference in readiness to change (SMD 0.06, 95% CI -0.27 to 0.39; 2 studies, 150 participants) and retention in treatment (SMD -0.09, 95% CI -0.34 to 0.16; 5 studies, 1295 participants), both with very low-certainty evidence. Comparing MI to assessment and feedback revealed no difference in substance use at short-term follow-up (SMD 0.09, 95% CI -0.05 to 0.23; 7 studies, 854 participants; low-certainty evidence). A small benefit for MI was shown at medium-term (SMD 0.24, 95% CI 0.08 to 0.40; 6 studies, 688 participants) and long-term follow-up (SMD 0.24, 95% CI 0.07 to 0.41; 3 studies, 448 participants), both with moderate-certainty evidence. None of the studies in this comparison measured substance use at the post-intervention time point, readiness to change, and retention in treatment. Comparing MI to another active intervention revealed no difference in substance use at any follow-up time point, all with low-certainty evidence: post-intervention (SMD 0.07, 95% CI -0.15 to 0.29; 3 studies, 338 participants); short-term (SMD 0.05, 95% CI -0.03 to 0.13; 18 studies, 2795 participants); medium-term (SMD 0.08, 95% CI -0.01 to 0.17; 15 studies, 2352 participants); and long-term follow-up (SMD 0.03, 95% CI -0.07 to 0.13; 10 studies, 1908 participants). There was no difference in readiness to change (SMD 0.15, 95% CI -0.00 to 0.30; 5 studies, 988 participants; low-certainty evidence) and retention in treatment (SMD -0.04, 95% CI -0.23 to 0.14; 12 studies, 1945 participants; moderate-certainty evidence). We downgraded the certainty of evidence due to inconsistency, study limitations, publication bias, and imprecision.

AUTHORS' CONCLUSIONS

Motivational interviewing may reduce substance use compared with no intervention up to a short follow-up period. MI probably reduces substance use slightly compared with assessment and feedback over medium- and long-term periods. MI may make little to no difference to substance use compared to treatment as usual and another active intervention. It is unclear if MI has an effect on readiness to change and retention in treatment. The studies included in this review were heterogeneous in many respects, including the characteristics of participants, substance(s) used, and interventions. Given the widespread use of MI and the many studies examining MI, it is very important that counsellors adhere to and report quality conditions so that only studies in which the intervention implemented was actually MI are included in evidence syntheses and systematic reviews. Overall, we have moderate to no confidence in the evidence, which forces us to be careful about our conclusions. Consequently, future studies are likely to change the findings and conclusions of this review.

Brief Alcohol Interventions are Effective through 6 Months: Findings from Marginalized Zero-inflated Poisson and Negative Binomial Models in a Two-step IPD Meta-analysis

To evaluate and optimize brief alcohol interventions (BAIs), it is critical to have a credible overall effect size estimate as a benchmark. Estimating such an effect size has been challenging because alcohol outcomes often represent responses from a mixture of individuals: those at high risk for alcohol misuse, occasional nondrinkers, and abstainers. Moreover, some BAIs exclusively focus on heavy drinkers, whereas others take a universal prevention approach. Depending on sample characteristics, the outcome distribution might have many zeros or very few zeros and overdispersion; consequently, the most appropriate statistical model may differ across studies. We synthesized individual participant data (IPD) from 19 studies in Project INTEGRATE (Mun et al., 2015b) that randomly allocated participants to intervention and control groups (N = 7,704 participants, 38.4% men, 74.7% White, 58.5% first-year students). We sequentially estimated marginalized zero-inflated Poisson (Long et al., 2014) or negative binomial regression models to obtain covariate-adjusted, study-specific intervention effect estimates in the first step, which were subsequently combined in a random-effects meta-analysis model in the second step. BAIs produced a statistically significant 8% advantage in the mean number of drinks at both 1-3 months (RR = 0.92, 95% CI = [0.85, 0.98]) and 6 months (RR = 0.92, 95% CI = [0.85, 0.99]) compared to controls. At 9-12 months, there was no statistically significant difference in the mean number of drinks between BAIs and controls. In conclusion, BAIs are effective at reducing the mean number of drinks through at least 6 months post intervention. IPD can play a critical role in deriving findings that could not be obtained in original individual studies or standard aggregate data meta-analyses.

The bystander intervention for problematic alcohol use model (BIPAUM)

Objective: The study aimed to identify phases of bystander intervention (BI) for problematic alcohol use (PAU) among college students. Participants: Twenty focus groups and nine interviews were conducted. Methods: Transcripts were thematically analyzed. Results: The phases of the Bystander Intervention for Problematic Alcohol Use Model (BIPAUM) include: (1) plan in advance, (2) notice and interpret a sign, (3) decide (i.e., assume responsibility, assess support/feasibility to intervene, and identify intervention strategy), (4) intervene, and (5) assess outcomes. Assessing outcomes loops to influence future behavior and each phase is influenced by barriers and facilitators. Conclusions: These unique phases should be considered when designing and evaluating intervention programs for PAU to meet students' needs and better reduce PAU. Future research should empirically test the BIPAUM. The results of the current study demonstrate a promising opportunity for applying BI to PAU, with the goal of reducing risky drinking among college students.

An integrated substance use treatment model for young adults with first-episode psychosis: A naturalistic pilot evaluation

AIM

Approximately 50% of individuals with first-episode psychosis meet criteria for a substance use disorder and these concurrent disorders are associated with worse long-term outcomes. Psychosocial interventions, including motivational interviewing as well as cognitive and behavioural therapies, have shown some evidence for effective treatment in substance use disorders; however, there is a paucity of existing studies that have successfully examined these interventions in first-episode psychosis.

METHODS

Participants (n = 64) received the concurrent disorders intervention, which included individual support alongside participation in at least one of two groups: a 4-week Motivational Engagement group utilizing motivational interviewing (n = 59) and an 8-week Relapse Prevention Training group emphasizing skill acquisition, which some participants entered directly (n = 5) and some participants entered following completion of the Motivational Engagement group (n = 16).

RESULTS

Participants who completed the Motivational Engagement group (n = 59) demonstrated significantly increased motivation to change substance use (d = -.0.58; t = -3.02, p < .01) and significantly decreased substance use frequency (d = 0.65; t = 3.26, p < .01). For participants who completed the Relapse Prevention Training group (n = 21), substance use frequency significantly decreased (d = 0.92; t = 3.46, p < .01) and self-efficacy in one's ability to maintain substance use changes significantly increased (d = -0.85; t = -3.59, p < .01).

CONCLUSIONS

This pilot evaluation suggests that motivational interviewing and relapse prevention skills training are acceptable and feasible interventions in the treatment of substance use disorders in young adults with first-episode psychosis.

The School of Hard Talks: A telehealth parent training group for caregivers of adolescents and young adults

AIM

A large body of evidence demonstrates the importance of the family environment in the developmental trajectory of mental illness in young people. Caregiver communication skills training represents a potential model for influencing the outcomes of adolescents and young adults struggling with emerging mental health and behavioural difficulties. The aim of the current study is to describe the development of a telehealth group training intervention for caregivers of adolescents and young adults, and to report the results of a pilot feasibility-effectiveness study that took place in 2020-2021.

METHODS

The "School of Hard Talks" intervention consisted of 8 h of training in communication skills consistent with motivational interviewing techniques. All pilot study participants were assigned to receive the intervention. Outcomes of interest were family conflict, caregiver stress, caregiver self-efficacy and expressed emotion (EE). Participants were assessed three times: prior to the intervention, after the intervention and 12 weeks later.

RESULTS

A total of 62 participants enrolled in the study, of whom 49 completed the intervention. Large, significant improvements were observed over time in all four domains of interest. Qualitative feedback from parents was very positive and added context to quantitative observations.

CONCLUSIONS

The School of Hard Talks was a feasible and effective intervention targeting both caregiver wellbeing as well as important mechanisms of risk for youth psychopathology, namely family conflict and EE. Further research involving a larger sample and a control condition are needed to confirm these findings.

Which interventions for alcohol use should be included in a universal healthcare benefit package? An umbrella review of targeted interventions to address harmful drinking and dependence

BACKGROUND

This study aimed to identify targeted interventions for the prevention and treatment of harmful alcohol use. Umbrella review methodology was used to summarise the effectiveness across a broad range of interventions, in order to identify which interventions should be considered for inclusion within universal health coverage schemes in low- and middle-income countries.

METHODS AND FINDINGS

We included systematic reviews with meta-analysis of randomised controlled trials (RCTs) on targeted interventions addressing alcohol use in harmful drinkers or individuals with alcohol use disorder. We only included outcomes related to alcohol consumption, heavy drinking, binge drinking, abstinence, or alcohol-attributable accident, injury, morbidity or mortality. PubMed, Embase, PsycINFO, Cochrane Database of Systematic Reviews, and the International HTA Database were searched from inception to 3 September 2021. Risk of bias of reviews was assessed using the AMSTAR2 tool. After reviewing the abstracts of 9,167 articles, results were summarised narratively and certainty in the body of evidence for each intervention was assessed using GRADE. In total, 86 studies met the inclusion criteria, of which the majority reported outcomes for brief intervention (30 studies) or pharmacological interventions (29 studies). Overall, methodological quality of included studies was low.

CONCLUSIONS

For harmful drinking, brief interventions, cognitive behavioural therapy, and motivational interviewing showed a small effect, whereas mentoring in adolescents and children may have a significant long-term effect. For alcohol use disorder, social network approaches and acamprosate showed evidence of a significant and durable effect. More evidence is required on the effectiveness of gamma-hydroxybutyric acid (GHB), nalmefene, and quetiapine, as well as optimal combinations of pharmacological and psychosocial interventions. As an umbrella review, we were unable to identify the extent to which variation between studies stemmed from differences in intervention delivery or variation between country contexts. Further research is required on applicability of findings across settings and best practice for implementation. Funded by the Thai Health Promotion Foundation, grant number 61-00-1812.

A randomized pilot trial of a mobile phone-based brief intervention with personalized feedback and interactive text messaging to reduce driving after cannabis use and riding with a cannabis impaired driver

INTRODUCTION

Driving after cannabis use (DACU) and riding with a cannabis-impaired driver (RWCD) are national public health concerns. Though driving impairments and increased crash risk make DACU and RWCD two of the riskiest cannabis-related behaviors, many continue to drive after use and ride with others who are under the influence and do not view DACU or RWCD as dangerous. The current study examined the efficacy of an accessible, low-cost, mobile phone-based brief intervention aimed at reducing DACU and RWCD among college cannabis users in the context of a randomized three-group pilot trial.

METHOD

Participants were 97 college cannabis users (67.4 % women; average age = 21.34; 80.4 % Caucasian) who endorsed DACU at least three times in the past three months. After completing baseline measures, the study randomly assigned participants to one of three conditions: a) a substance impaired-driving personalized feedback plus MI-style interactive text messaging intervention (PF + MIT); b) a substance impaired-driving personalized feedback only intervention (PF); and c) a substance information control condition (IC). All conditions completed outcome measures three months postintervention.

RESULTS

Generalized linear mixed models (GLMM) analyses indicated that after controlling for sex, cannabis users in the PF + MIT condition significantly reduced DACU and RWCD over time compared to those in the IC condition.

CONCLUSIONS

These findings provide preliminary support for the short-term efficacy of a mobile phone-based intervention in decreasing DACU and RWCD among college cannabis users. Future research should determine whether these reductions in driving behaviors persist past three months.

Proof of Concept for the FLEX Intervention: Feasibility of Home Based Coaching to Improve Physical Activity Outcomes and Viral Load Suppression among African American Youth Living with HIV

FLEX is a Motivational Interviewing, home-based coaching program that concurrently targets HIV-related and physical activity goals among African American youth living with HIV in the United States. To create and pilot test FLEX, we leveraged a 2-step exploratory sequential mixed methods design informed by the ORBIT model with initial qualitative work followed by pre-post analysis of quantitative outcomes, concluding with qualitative exit surveys. Data were evaluated pre- and 3-months post-intervention. Recruitment was 90%. Participants reported high program satisfaction and program adherence (76% completion rate). Preliminary findings indicate reductions in participants’ viral loads and improvements across 4 measures of physical activity.

[Evidence-based alcohol prevention-what does effectiveness research recommend? : Results of the 2020 BZgA review of reviews on addiction prevention]

BACKGROUND

A substantial group of adolescents and young adults engage in risky alcohol use and there is a need for alcohol prevention. The 2020 BZgA review of reviews on addiction prevention provides the best available scientific knowledge on effectiveness of prevention measures for young people.

RESEARCH QUESTION

Which approaches show preventive effects on alcohol use in different prevention settings?

METHODS

A systematic literature search in June 2017 in seven international databases resulted in 28,949 hits. Inclusion criteria were a review or meta-analysis study type, a 2012-2017 publication date, a universal or selective target group, age up to 25 years, and a target behavior of alcohol consumption. Exclusion criteria were target group people with substance use disorders and target behavior risk factors. The three authors performed a systematic content analysis of 34 alcohol-related publications and assessed their methodology using AMSTAR (A MeaSurement Tool to Assess systematic Reviews). Conclusions and recommendations were framed by consensus among all authors.

RESULTS

Based on a total number of 53 conclusions on the effectiveness of alcohol prevention approaches depending on setting (family, school, college, media, health care, and community) and target group, it can be recommended - among other things - to implement family programs and parenting training, behavioral programs targeting specific personal and social skills, brief interventions with feedback, and mentoring programs. No recent reviews that investigated the effectiveness of alcohol policies at the community or national level could be identified.

CONCLUSIONS

Behavioral alcohol prevention is effective. It is recommended to address specific age and target groups in different settings by using specific interventions. Consensus is needed with regard to what kind of evidence proves effectiveness of environmental prevention measures.

BRIEF MOTIVATIONAL INTERVENTION FOR SUBSTANCE USE MAY DECREASE VIOLENCE AMONG HEAVY ALCOHOL USERS IN A JAIL DIVERSION PROGRAM

Rates of harmful alcohol use are high among justice-involved individuals and may contribute to violent recidivism. Robust treatments for alcohol-related violence in criminal justice systems are thus a public health priority. In this analysis of existing randomized controlled trial data (N = 105), we examined the impact of a brief motivational intervention (BMI) for harmful substance use on violent recidivism among individuals in a pretrial jail diversion program. Results indicated that, after controlling for violence history, the intervention's impact on violent recidivism was moderated by baseline harmful alcohol use. Specifically, among people with severe alcohol problems at baseline, the BMI + standard care group had less violent recidivism at a 1-year follow-up than participants randomized to standard care alone. This finding was unchanged when we accounted for psychopathic traits. Our study provides preliminary evidence that a BMI may be useful for decreasing violent recidivism among heavy drinkers in criminal justice systems.

Do Brief Alcohol Interventions Reduce Driving After Drinking Among College Students? A Two-step Meta-analysis of Individual Participant Data

Aims

College students who drink are at an increased risk of driving after drinking and alcohol-involved traffic accidents and deaths. Furthermore, the persistence of driving after drinking over time underscores a need for effective interventions to prevent future drunk driving in adulthood. The present study examined whether brief alcohol interventions (BAIs) for college students reduce driving after drinking.

Methods

A two-step meta-analysis of individual participant data (IPD) was conducted using a combined sample of 6801 college students from 15 randomized controlled trials (38% male, 72% White and 58% first-year students). BAIs included individually delivered Motivational Interviewing with Personalized Feedback (MI + PF), Group Motivational Interviewing (GMI), and stand-alone Personalized Feedback (PF) interventions. Two outcome variables, driving after two+/three+ drinks and driving after four+/five+ drinks, were checked, harmonized and analyzed separately for each study and then combined for meta-analysis and meta-regression analysis.

Results

BAIs lowered the risk of driving after four+/five+ drinks (19% difference in the odds of driving after drinking favoring BAIs vs. control), but not the risk of driving after two+/three+ drinks (9% difference). Subsequent subgroup analysis indicated that the MI + PF intervention was comparatively better than PF or GMI.

Conclusions

BAIs provide a harm reduction approach to college drinking. Hence, it is encouraging that BAIs reduce the risk of driving after heavy drinking among college students. However, there may be opportunities to enhance the intervention content and timing to be more relevant for driving after drinking and improve the outcome assessment and reporting to demonstrate its effect.

Alcohol intake reduction for controlling hypertension

BACKGROUND

High blood pressure constitutes one of the leading causes of mortality and morbidity all over the world. At the same time, heavy drinking increases the risk for developing cardiovascular diseases, including cardiomyopathy, hypertension, atrial arrhythmias, or stroke. Several studies have already assessed specifically the relationship between alcohol intake and hypertension. However, the potential effect on blood pressure of alcohol intake reduction interventions is largely unknown.

OBJECTIVES

To assess the effect of any intervention to reduce alcohol intake in terms of blood pressure decrease in hypertensive people with alcohol consumption compared to a control intervention or no intervention at all. To determine additional effects related to mortality, major cardiovascular events, serious adverse events, or quality of life.

SEARCH METHODS

The Cochrane Hypertension Information Specialist searched the following databases for randomised controlled trials up to June 2020: the Cochrane Hypertension Specialised Register, the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 5, 2020), MEDLINE Ovid (from 1946), MEDLINE Ovid Epub Ahead of Print, and MEDLINE Ovid In-Process, Embase Ovid (from 1974), ClinicalTrials.gov and the World Health Organization International Clinical Trials Registry Platform. Trial authors were contacted when needed and no language restrictions were applied.

SELECTION CRITERIA

We included randomised controlled trials with minimum 12 weeks duration and including 50 or more subjects per group with quantitative measurement of alcohol consumption and/or biological measurement of the outcomes of interest. Participants were adults (16 years of age or older) with systolic blood pressure (SBP) greater than 140 mmHg and diastolic blood pressure (DBP) greater than 90 mmHg, and SBP ≥ 130 or DBP ≥ 80 mmHg in participants with diabetes. We included any intervention implemented to reduce their alcohol intake.

DATA COLLECTION AND ANALYSIS

Two review authors independently assessed search results and extracted data using standard methodological procedures adopted by Cochrane.

MAIN RESULTS

A total of 1210 studies were screened. We included one randomised controlled trial involving a total of 269 participants with a two-year follow-up. Individual patient data for all participants were provided and used in this review. No differences were found between the cognitive-behavioural intervention group and the control group for overall mortality (RR 0.72, 95% CI 0.16 to 3.17; low-certainty evidence), cardiovascular mortality (not estimable) and cardiovascular events (RR 0.80, 95% CI 0.36 to 1.79; very low-certainty evidence). There was no statistical difference in systolic blood pressure (SBP) reduction (Mean Difference (MD) -0.92 mmHg, 95% confidence interval (CI) -5.66 to 3.82 mmHg; very low-certainty evidence) or diastolic blood pressure (DBP) decrease (MD 0.98 mmHg, 95% CI -1.69 to 3.65 mmHg; low-certainty evidence) between the cognitive-behavioural intervention group and the control group. We also did not find any differences in the proportion of subjects with SBP < 140 mmHg and DBP < 90 mmHg (Risk Ratio (RR) 1.21, 95% CI 0.88 to 1.65; very low-certainty evidence). Concerning secondary outcomes, the alcohol intake was significantly reduced in the cognitive-behavioural intervention compared with the control group (MD 191.33 g, 95% CI 85.36 to 297.30 g). We found no differences between the active and control intervention in the proportion of subjects with lower-risk alcohol intake versus higher-risk and extreme drinkers at the end of the study (RR 1.04, 95% CI 0.68 to 1.60). There were no estimable results for the quality of life outcome.

AUTHORS' CONCLUSIONS

An intervention for decreasing alcohol intake consumption did not result in differences in systolic and diastolic blood pressure when compared with a control intervention, although there was a reduction in alcohol intake favouring the active intervention. No differences were found either for overall mortality, cardiovascular mortality or cardiovascular events. No data on serious adverse events or quality of life were available to assess. Adequate randomised controlled trials are needed to provide additional evidence on this specific question.

Social Media Interventions for Risky Drinking Among Adolescents and Emerging Adults: Protocol for a Randomized Controlled Trial

BACKGROUND

Despite intervention efforts to date, the prevalence of risky drinking among adolescents and emerging adults remains high, increasing the risk for health consequences and the development of alcohol use disorders. Peer influences are particularly salient among this age group, including via social media. Thus, the development of efficacious early interventions for youth, delivered with a broad reach via trained peers on social media, could have an important role in addressing risky drinking and concomitant drug use.

OBJECTIVE

This paper describes the protocol of a randomized controlled trial (RCT) testing the efficacy of a social media intervention among adolescents and emerging adults who meet the criteria for risky drinking (using the Alcohol Use Disorders Identification Test-Consumption [AUDIT-C]), delivered with and without financial incentives for participation, compared with an attention placebo control condition (ie, entertaining social media content), on alcohol consumption and consequences.

METHODS

This RCT involved recruiting 955 youths (aged 16-24 years) via advertisements on Facebook and Instagram to self-administer a brief web-based screening survey. Those screening positive for past 3-month risky drinking (AUDIT-C positive: ages 16-17 years: ≥3 females and ≥4 males; and ages 18-24 years: ≥4 females and ≥5 males) were eligible for the RCT. After providing consent (a waiver of parental consent was obtained for minors), participants completed a web-based baseline survey and several verification procedures, including a selfie photo matched to Facebook profile photos. Participants were then randomized to join invitation-only secret Facebook groups, which were not searchable or viewable by parents, friends, or anyone not recruited by the study. The 3 conditions were social media intervention with incentives, social media intervention without incentives (SMI), and attention placebo control. Each condition lasted 8 weeks and consisted of bachelor's-level and master's-level therapist electronic coaches posting relevant content and responding to participants' posts in a manner consistent with Motivational Interviewing. Participants in the control condition and SMI condition did not receive payments but were blind to condition assignment between these 2 conditions. Follow-ups are ongoing and occur at 3, 6, and 12 months poststart of the groups.

RESULTS

We enrolled 955 participants over 10 waves of recruitment who screened positive for risky drinking into the RCT.

CONCLUSIONS

The findings of this study will provide the critical next step in delivering early alcohol interventions to the youth, capitalizing on social media platforms, which could have significant public health impact by altering alcohol use trajectories of adolescents and emerging adults engaged in risky drinking.

Perceptions of the Use of Alcohol and Drugs after Sudden Bereavement by Unnatural Causes: Analysis of Online Qualitative Data

Bereavement is associated with an increased risk of psychiatric morbidity and all-cause mortality, particularly in younger people and after unnatural deaths. Substance misuse is implicated but little research has investigated patterns of drug or alcohol use after bereavement. We used a national online survey to collect qualitative data describing whether and how substance use changes after sudden bereavement. We conducted thematic analysis of free-text responses to a question probing use of alcohol and drugs after the sudden unnatural (non-suicide) death of a family member or a close friend. We analysed data from 243 adults in British Higher Education Institutions aged 18-40, identifying two main themes describing post-bereavement alcohol or drug use: (1) sense of control over use of drugs or alcohol (loss of control versus self-discipline), (2) harnessing the specific effects of drugs or alcohol. Across themes we identified age patterning in relation to substance misuse as a form of rebellion among those bereaved in childhood, and gender patterning in relation to men using alcohol to help express their emotions. The limitations of our sampling mean that these findings may not be generalizable from highly-educated settings to young people in the general population. Our findings describe how some young bereaved adults use drugs and alcohol to help them cope with traumatic loss, and suggest how clinicians might respond to any difficulties controlling substance use.

Prevention, screening, and treatment for heavy drinking and alcohol use disorder

Heavy drinking and alcohol use disorder are major public health problems. Practitioners not specialising in alcohol treatment are often unaware of the guidelines for preventing, identifying, and treating heavy drinking and alcohol use disorder. However, a consensus exists that clinically useful and valuable tools are available to address these issues. Here, we review existing information and developments from the past 5 years in these areas. We also include information on heavy drinking and alcohol use disorder among individuals with co-occurring psychiatric disorders, including drug use disorders. Areas covered include prevention; screening, brief intervention, and referral for treatment; evidence-based behavioural interventions; medication-assisted treatment; technology-based interventions (eHealth and mHealth); and population-level interventions. We also discuss the key topics for future research.

Severe alcohol intoxication among Canadian Youth: A 2-year surveillance study

Purpose

To obtain data on Canadian youth, aged 11 to 15 years, presenting to paediatric emergency departments, with severe alcohol intoxication and to describe demographics, presentations to hospital, concurrent substance use, comorbidities, and short-term outcomes of admission to emergency departments.

Methods

Between March 2013 and February 2015, through the established methodology of the Canadian Paediatric Surveillance Program, Canadian paediatricians and paediatric subspecialists were surveyed monthly to identify cases of young adolescents presenting to paediatric emergency departments across Canada with severe alcohol intoxication. Those that identified cases were subsequently sent a detailed questionnaire. The detailed questionnaires were then screened to ensure the reported cases met the study's inclusion criteria.

Results

A total of 39 cases (18 females and 21 males) were included in the final analysis. Overall, results indicate over 90% of presenting youth had consumed spirits, 39% had concurrent substance use and 46% experienced serious medical morbidity. Almost two-thirds of youth were admitted to hospital for a period ranging from 10 hours to 5 days; 12 youth required intubation. Follow-up referrals were provided to two-thirds of youth, with variable supports given. No statistically significant differences between sexes were noted for blood alcohol level or concurrent substance use.

Conclusion

Although rates of alcohol use in adolescents have been steadily decreasing, results from this surveillance study suggest that severe intoxication arising from the use of alcohol alone, and with concurrent substance use, results in significant immediate health consequences in young adolescents. Results from this study also highlight characteristics of patients, initial treatments and initial referrals across Canadian paediatric healthcare facilities, the results of which highlight variability and may aid in the guidance of a future longitudinal study, prevention strategies, and public health messaging.

Ethanol Exposure Induces Microglia Activation and Neuroinflammation through TLR4 Activation and SENP6 Modulation in the Adolescent Rat Hippocampus

The ethanol-induced toll-like receptor 4 (TLR4) signal activation of microglia and neuroinflammation are observed in both adolescent and adult rat brains, but the regulatory mechanisms of some TLR4 signaling-related factors in this process are still unclear. SUMO-specific protease 6 (SENP6) inhibits neuroinflammation by dampening nuclear factor kappa-B (NF-κB) activation via the de-SUMOylation of NF kappa-B essential modulator (NEMO). This study investigates the effects of long-term ethanol consumption on neuroinflammation in the hippocampus of adolescent rats and the regulatory roles of TLR4 and SENP6. Twenty-one days of ethanol exposure in adolescent rats were used to develop an animal model. The number of microglia, microglial activation, and the expression of TLR4 in the hippocampus of adolescent rats were examined by immunoreactivity. The levels of TLR4, activation of NF-κB including IkB-α and p-NF-κB-p65, and SENP6 were measured by western blotting. Proinflammatory cytokines including TNF-α, IL-1β, and IL-6 were measured by enzyme-linked immunosorbent assay. The NF-κB activation and proinflammatory cytokines released in overexpressed SENP6 and siRNA targeting SENP6 microglial cells after treatment with ethanol were estimated in vitro. This study found that alcohol exposure increased the number of activated microglia and the levels of p-NF-κB-p65 and proinflammatory cytokines, while it decreased the SENP6 level in wild-type rats, but not in TLR4 knockout rats. The ethanol-induced increases of p-NF-κB-p65, TNF-α, and IL-1β were dampened by overxpression of SENP6 and enhanced in SENP6-siRNA microglia. Our data suggest that ethanol exposure during adolescence induces the microglia-mediated neuroinflammation via TLR4 activation, and SENP6 plays an essential role in dampening NF-κB activation and neuroinflammation.

A Mobile Phone-Based Brief Intervention With Personalized Feedback and Text Messaging Is Associated With Reductions in Driving After Drinking Among College Drinkers

OBJECTIVE

Driving after drinking (DAD) among college students remains a significant public health concern and is perhaps the single riskiest drinking-related behavior. Counselor-delivered and web-based Brief Alcohol Interventions (BAIs) have been shown to reduce DAD among college students, but to date no study has evaluated the efficacy of a single-session mobile phone-based BAI specific to DAD. The present study examined whether a driving-specific BAI delivered via mobile phone would significantly decrease DAD among college students compared to an informational control.

METHOD

Participants were 84 college students (67.1% women; average age = 23; 52.4% White) who endorsed driving after drinking two or more drinks at least twice in the past 3 months. After completing baseline measures, participants were randomly assigned to receive either (a) DAD information or (b) DAD mobile BAI that included personalized feedback and interactive text messaging. Participants completed outcome measures at 3-month follow-up.

RESULTS

Repeated-measures mixed modeling analyses revealed that students receiving the mobile phone-based BAI reported significantly greater reductions in likelihood of DAD (three or more drinks) and the number of drinks consumed before driving than students in the information condition at 3-month follow-up.

CONCLUSIONS

These findings provide preliminary support for the short-term efficacy of a mobile phone-based BAI for reducing DAD among college students.

Motivational interviewing for smoking cessation

BACKGROUND

Motivational Interviewing (MI) is a directive patient-centred style of counselling, designed to help people to explore and resolve ambivalence about behaviour change. It was developed as a treatment for alcohol abuse, but may help people to a make a successful attempt to stop smoking.

OBJECTIVES

To evaluate the efficacy of MI for smoking cessation compared with no treatment, in addition to another form of smoking cessation treatment, and compared with other types of smoking cessation treatment. We also investigated whether more intensive MI is more effective than less intensive MI for smoking cessation.

SEARCH METHODS

We searched the Cochrane Tobacco Addiction Group Specialised Register for studies using the term motivat* NEAR2 (interview* OR enhanc* OR session* OR counsel* OR practi* OR behav*) in the title or abstract, or motivation* as a keyword. We also searched trial registries to identify unpublished studies. Date of the most recent search: August 2018.

SELECTION CRITERIA

Randomised controlled trials in which MI or its variants were offered to smokers to assist smoking cessation. We excluded trials that did not assess cessation as an outcome, with follow-up less than six months, and with additional non-MI intervention components not matched between arms. We excluded trials in pregnant women as these are covered elsewhere.

DATA COLLECTION AND ANALYSIS

We followed standard Cochrane methods. Smoking cessation was measured after at least six months, using the most rigorous definition available, on an intention-to-treat basis. We calculated risk ratios (RR) and 95% confidence intervals (CI) for smoking cessation for each study, where possible. We grouped eligible studies according to the type of comparison. We carried out meta-analyses where appropriate, using Mantel-Haenszel random-effects models. We extracted data on mental health outcomes and quality of life and summarised these narratively.

MAIN RESULTS

We identified 37 eligible studies involving over 15,000 participants who smoked tobacco. The majority of studies recruited participants with particular characteristics, often from groups of people who are less likely to seek support to stop smoking than the general population. Although a few studies recruited participants who intended to stop smoking soon or had no intentions to quit, most recruited a population without regard to their intention to quit. MI was conducted in one to 12 sessions, with the total duration of MI ranging from five to 315 minutes across studies. We judged four of the 37 studies to be at low risk of bias, and 11 to be at high risk, but restricting the analysis only to those studies at low or unclear risk did not significantly alter results, apart from in one case - our analysis comparing higher to lower intensity MI.We found low-certainty evidence, limited by risk of bias and imprecision, comparing the effect of MI to no treatment for smoking cessation (RR = 0.84, 95% CI 0.63 to 1.12; I² = 0%; adjusted N = 684). One study was excluded from this analysis as the participants recruited (incarcerated men) were not comparable to the other participants included in the analysis, resulting in substantial statistical heterogeneity when all studies were pooled (I² = 87%). Enhancing existing smoking cessation support with additional MI, compared with existing support alone, gave an RR of 1.07 (95% CI 0.85 to 1.36; adjusted N = 4167; I² = 47%), and MI compared with other forms of smoking cessation support gave an RR of 1.24 (95% CI 0.91 to 1.69; I² = 54%; N = 5192). We judged both of these estimates to be of low certainty due to heterogeneity and imprecision. Low-certainty evidence detected a benefit of higher intensity MI when compared with lower intensity MI (RR 1.23, 95% CI 1.11 to 1.37; adjusted N = 5620; I² = 0%). The evidence was limited because three of the five studies in this comparison were at risk of bias. Excluding them gave an RR of 1.00 (95% CI 0.65 to 1.54; I² = n/a; N = 482), changing the interpretation of the results.Mental health and quality of life outcomes were reported in only one study, providing little evidence on whether MI improves mental well-being.

AUTHORS' CONCLUSIONS

There is insufficient evidence to show whether or not MI helps people to stop smoking compared with no intervention, as an addition to other types of behavioural support for smoking cessation, or compared with other types of behavioural support for smoking cessation. It is also unclear whether more intensive MI is more effective than less intensive MI. All estimates of treatment effect were of low certainty because of concerns about bias in the trials, imprecision and inconsistency. Consequently, future trials are likely to change these conclusions. There is almost no evidence on whether MI for smoking cessation improves mental well-being.

Using an Experimental Medicine Approach to Identify Novel Determinants of Addiction

Our understanding and effectiveness in treating addiction is not fully adequate. Therefore, perhaps developing a pragmatic theory for identifying novel determinants and potential interventions is needed. The experimental medicine approach, derived from Claude Bernard, proposes a methodology for inductive theory development and suggests interventions directed at targets closely aligned with the underlying mechanisms of the disorder. The steps of theory development under this approach are intended to (1) identify an intervention target; (2) develop assays to verify target measurement; (3) engage the target via experiment or intervention; and (4) test the degree to which target engagement produces other therapeutically useful changes in the disorder. In this article, we review these steps in detail using an example from our work. That is, shortened temporal windows (target) is frequently observed among those who are addicted. Delay discounting is an assay used to measure that target. We and others have demonstrated manipulation of the target, delay discounting, is associated with changing the drug valuation among those with addiction. We conclude with a culmination of the experimental medicine approach by proposing a recently developed hypothesis of substance use disorder, Reinforcer Pathology 2.0.

A randomized clinical trial evaluating the efficacy of a brief alcohol intervention supplemented with a substance-free activity session or relaxation training

OBJECTIVE

Behavioral economic theory suggests that a reduction in alcohol use is most likely when there is an increase in rewarding substance-free activities. Anxiety has also been linked to heavy drinking, and strategies to reduce anxiety may enhance alcohol interventions. The goal of this 2-site randomized controlled clinical trial was to evaluate the efficacy of a brief alcohol intervention that was supplemented with either a behavioral economic substance-free activity session (SFAS) or a relaxation training (Relaxation training [RT]) session.

METHOD

Participants were 393 college students (61% female, mean age = 18.77 years) who reported 2 or more past-month heavy drinking episodes. Participants were randomized to 1 of 3 conditions: (a) assessment; (b) alcohol brief motivational intervention (BMI) plus SFAS; or (c) BMI plus RT. Both treatment conditions included 2 in-person sessions plus a phone booster session. Outcomes were evaluated 1-, 6-, 12-, and 16-months postintervention.

RESULTS

Generalized linear mixed models indicated that the combination of a BMI plus either the SFAS or RT was associated with significant reductions in alcohol use and problems across the 16-month follow-up compared with assessment only. There were no significant differences between the two active treatment conditions. Changes in proportional reinforcement from substance-related activities, and protective behavioral strategies mediated treatment effects.

CONCLUSION

Two-session (plus booster) interventions that combine BMI and either substance-free activity enhancement or RT can result in enduring reductions in alcohol misuse among college drinkers. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

The phenotype of recovery III: Delay discounting predicts abstinence self-efficacy among individuals in recovery from substance use disorders

Abstinence self-efficacy (ASE) and delay discounting predict treatment outcomes and risk of relapse. Associations between delay discounting and ASE among individuals in recovery from substance use have not been investigated. Data from 216 individuals in recovery from substance abuse recruited from The International Quit & Recovery Registry, an ongoing online data collection program used to understand addiction and how people succeed in recovery, were included in the analysis. Discounting rates were assessed using an adjusting-delay task, and ASE was assessed using the Relapse Situation Efficacy Questionnaire (RSEQ). Delay discounting was a significant predictor of ASE, even after controlling for age, gender, race, ethnicity, annual income, education level, marital status, and primary addiction. Context-specific factors of relapse included Negative Affect, Positive Affect, Restrictive Situations (to drug use), Idle Time, Social-Food Situations, Low Arousal, and Craving. A principal component analysis of RSEQ factors in the current sample revealed that self-efficacy scores were primarily unidimensional and not situation specific. The current study expands the generality of delay discounting and indicates that discounting rates predict ASE among individuals in recovery from substance use disorders. This finding supports the recent characterizations of delay discounting as a candidate behavioral marker of addiction and may serve as a basis to better identify and target subgroups that need unique or more intensive interventions to address higher risks of relapse and increase their likelihood of abstinence.

A Meta-Analysis of the Efficacy of Case Management for Substance Use Disorders: A Recovery Perspective

Background: Case management is a client-centered approach to improve the coordination and continuity of service delivery, especially for persons with substance use disorders (SUD) and multiple and complex support needs. This intervention supports individuals by helping them identify needed services, facilitate linkage with services, and promote participation and retention in services. However, it is questionable whether case management is equally effective in promoting recovery and aspects of personal functioning. The objective was to conduct an updated meta-analysis and to assess whether case management was more effective than treatment as usual (TAU) among persons with SUD for improving treatment-related (e.g., successful linkage with and retention in treatment) as well as personal functioning outcomes (e.g., substance use). Methods: This meta-analysis focuses on randomized controlled trials (RCTs) that included persons with alcohol or drug use disorders and compared case management with TAU. To be eligible, interventions had to meet core case management functions as defined in the literature. We conducted searches of the following databases to May 2017: the Cochrane Drugs and Alcohol Specialized Register, CENTRAL, PubMed, Embase, CINAHL, and Web of Science. Also, reference lists of retrieved publications were scanned for relevant (un)published studies. Results: The overall effect size for case management compared to TAU across all outcome categories and moments was small and positive (SMD = 0.18, 95% CI 0.07-0.28), but statistically significant. Effects were considerably larger for treatment tasks (SMD = 0.33, 95% CI 0.18-0.48) than for personal functioning outcomes (SMD = 0.06, 95% CI -0.02 to 0.15). The largest effect sizes were found for retention in substance abuse treatment and linkage with substance abuse services. Moderator effects of case management models and conditions were assessed, but no significant differences were observed. Conclusions: The primary results from earlier meta-analyses were supported: case management is more effective than TAU conditions for improving outcomes, but this effect is significantly larger for treatment-related tasks than for personal functioning outcomes. Case management can be an important supplement to available services for improving linkage and retention, although further research is needed to assess its potential for supporting recovery from a longitudinal perspective.

New steps for treating alcohol use disorder

Alcohol use disorder is a complex syndrome with multiple treatment points including drug-induced pathology, withdrawal management, behavioral/cognitive strategies, and relapse prevention. These different components may be complicated by genotype and phenotype. A huge milestone for the treatment of alcohol use disorder across several countries in the last 10 years was the introduction of practice guidelines integrating clinical expertise and research evidence. These provide a summary of interventions that have been shown to be effective following rigorous and replicated clinical trials. Inspection of these guidelines reveals good consistency, but little evidence of progress in treatment approaches for alcohol use disorder over the past decade. In this mini-review, we discuss emerging treatments for alcohol use disorder that may supplement or improve the evidence-based treatments that are currently recommended. New medications, the emergence of digital technology, and other novel approaches such as transcranial magnetic stimulation are all discussed with reference to treatments already in practice. We also consider how individual differences in genotype and phenotype may affect outcomes. Together with improvements in technology, this knowledge offers a powerful tool for designing personalized approaches to treatment, and hence improving prognosis for rehabilitation programs.

A developmental-based motivational intervention to reduce alcohol and marijuana use among non-treatment-seeking young adults: a randomized controlled trial

AIMS

To test the hypothesis that among non-treatment-seeking emerging adults (EA) who both use marijuana and have alcohol binges, a brief, longitudinally delivered, developmentally based motivational intervention would show greater reductions in the use of these two substances compared with a health education control condition.

DESIGN

Parallel, two-group, randomized controlled trial with follow-up interventions conducted at 1, 3, 6 and 9 months and final assessments at 12 and 15 months.

SETTING

Hospital-based research unit in the United States.

PARTICIPANTS

Community-based 18-25-year-olds who reported at least monthly binge drinking and at least weekly marijuana use.

INTERVENTION

Motivational intervention (EA-MI) focused primarily on themes of emerging adulthood (identity exploration, instability, self-focus, feeling in-between, a sense of possibilities) and the subjects' relationship to substance use (n = 110) compared with an attention-matched health education control condition (n = 116).

MEASUREMENTS

The primary outcomes were days of binge alcohol, marijuana and dual use day as measured using the timeline follow-back method analysing the treatment by time interaction to determine relative differences in the rate of change between intervention arms.

FINDINGS

At baseline, the mean rate (days/30) of binge drinking was 5.23 (± 4.31) of marijuana use was 19.4 (± 10.0) and of dual (same day) use was 4.11 (± 4.13). Relative to baseline, there were reductions in the rate of binge alcohol use, marijuana use and days of combined binge alcohol and marijuana use (P < 0.001) at all follow-up assessments. However, the treatment × time interaction was not statistically significant for alcohol (P = 0.37), for marijuana (P = 0.07) or for dual use (P = 0.55). Averaged over all follow-ups, mean reductions in binge, marijuana and dual use days were 1.16, 1.45 and 1.08, respectively, in the health education arm, and 1.06, 1.69 and 0.96 in EA-MI. Bayes factors were < 0.01 for frequency of binge alcohol use and frequency of dual binge alcohol and marijuana and 0.016 for marijuana use.

CONCLUSIONS

A brief, longitudinally delivered, developmentally based motivational intervention for young adults did not produce reductions in binge alcohol, marijuana use or dual use days relative to a control condition.

Binge Alcohol Exposure Causes Neurobehavioral Deficits and GSK3β Activation in the Hippocampus of Adolescent Rats

Heavy alcohol exposure causes profound damage to the adolescent brain, particularly the hippocampus, which underlie some behavioral deficits. However, the underlying molecular mechanisms remain inconclusive. The current study sought to determine whether binge alcohol exposure affects the hippocampus-related behaviors and key signaling proteins that may mediate alcohol neurotoxicity in adolescent rats. Alcohol exposure reduced the number of both NeuN-positive and doublecortin-positive cells in the hippocampus. Alcohol also induced neurodegeneration which was confirmed by ultrastructural analysis by electronic microscopy and was accompanied with the activation of microglia. Binge alcohol exposure impaired spatial learning and memory which was evaluated by the Morris water maze. However, alcohol did not alter the spontaneous locomotor activity which was determined by the open field test. GSK3β is a multi-function serine/threonine protein kinase regulating both neuronal survival and neurogenesis and plays an important role in various neurodegenerative disorders. We have previously shown that GSK3β is a key mediator of alcohol-induced neuron apoptosis in the developing brain. We showed here binge alcohol exposure caused GSK3β activation by inducing dephosphorylation at Ser9 without affecting the phosphorylation of Tyr216 in the hippocampus. Thus, GSK3β may be involved in binge alcohol exposure-induced neuronal damage to the adolescent hippocampus.

The Adolescent's Competency for Interacting with Alcohol as a Determinant of Intake: The Role of Self-Regulation

The competency for interacting with alcohol is a highly useful Educational Psychology model for preventing and for understanding the different behavioral levels of this interaction. Knowledge of facts, concepts and principles about alcohol use, self-regulated behavior, and attitudes toward alcohol are predictive of adequate interaction with alcohol. The objective of this study was to empirically evaluate this postulated relationship. A total of 328 Spanish adolescents participated, between the ages of 12 and 17. All were enrolled in 1st–4th year of compulsory secondary education, in the context of the ALADO Program for prevention of alcohol intake in adolescents. An ex post facto design was used, with inferential analyses and SEM analyses. Results show an interdependence relationship, with significant structural prediction between the behavioral levels defined and the level of alcohol intake, with principles, self-regulating control and attitudes carrying more weight. Analyses are presented, as are implications for psychoeducational intervention using preventive programs based on this competency model.

A pilot randomized trial of Motivational Interviewing compared to Psycho-Education for reducing and preventing underage drinking in American Indian adolescents

Underage drinking is an important public health issue for American Indian and Alaska Native (AI/AN) adolescents, as it is for U. S. teens of all ethnicities. One of the demonstrated risk factors for the development of alcohol use disorders in AI/AN is early age of initiation of drinking. To address this issue a randomized trial to assess the efficacy of Motivational Interviewing (MI) compared to Psycho-Education (PE) to reduce and prevent underage drinking in AI/AN youth was developed and implemented. Sixty-nine youth received MI or PE and 87% were assessed at follow-up. For teens who were already drinking, participating in the intervention (MI or PE) was associated, at follow-up, with lower quantity×frequency (q×f) of drinking (p=0.011), fewer maximum drinks per drinking occasion (p=0.004), and fewer problem behaviors (p=0.009). The MI intervention resulted in male drinkers reporting a lower q×f of drinking (p=0.048) and female drinkers reporting less depression (p=0.011). In teens who had not started drinking prior to the intervention, 17% had initiated drinking at follow-up. As a group they reported increased quantity×frequency of drinking (p=0.008) and maximum drinks (p=0.047), but no change in problem behaviors. These results suggest that intervening against underage drinking using either MI or PE in AI/AN youth can result in reduced drinking, prevention of initiation of drinking, and other positive behavioral outcomes. Brief interventions that enhance motivation to change as well as Psycho-Education may provide a successful approach to reducing the potential morbidity of underage drinking in this high-risk group.

Betting on the fastest horse: Using computer simulation to design a combination HIV intervention for future projects in Maharashtra, India

Objective

To inform the design of a combination intervention strategy targeting HIV-infected unhealthy alcohol users in Maharashtra, India, that could be tested in future randomized control trials.

Methods

Using probabilistic compartmental simulation modeling we compared intervention strategies targeting HIV-infected unhealthy alcohol users on antiretroviral therapy (ART) in Maharashtra, India. We tested interventions targeting four behaviors (unhealthy alcohol consumption, risky sexual behavior, depression and antiretroviral adherence), in three formats (individual, group based, community) and two durations (shorter versus longer). A total of 5,386 possible intervention combinations were tested across the population for a 20-year time horizon and intervention bundles were narrowed down based on incremental cost-effectiveness analysis using a two-step probabilistic uncertainty analysis approach.

Results

Taking into account uncertainty in transmission variables and intervention cost and effectiveness values, we were able to reduce the number of possible intervention combinations to be used in a randomized control trial from over 5,000 to less than 5. The most robust intervention bundle identified was a combination of three interventions: long individual alcohol counseling; weekly Short Message Service (SMS) adherence counseling; and brief sex risk group counseling.

Conclusions

In addition to guiding policy design, simulation modeling of HIV transmission can be used as a preparatory step to trial design, offering a method for intervention pre-selection at a reduced cost.

Use of aids for smoking cessation and alcohol reduction: A population survey of adults in England

Background

It is important for policy planning to chart the methods smokers and high-risk drinkers use to help them change their behaviour. This study assessed prevalence of use, and characteristics of users, of support for smoking cessation and alcohol reduction in England.

Methods

Data were used from the Smoking and Alcohol Toolkit Studies, which involve monthly face-to-face computer-assisted interviews of adults aged 16+ in England. We included data collected between June 2014 and July 2015 on 1600 smokers who had made at least one quit attempt and 911 high-risk drinkers (defined as scores >8+ on the full AUDIT or 5+ on questions 1–3 of the AUDIT-C) who had made an attempt to cut down in the past 12 months. Participants provided information on their socio-demographic characteristics and use of aids during their most recent quit attempt including pharmacotherapy, face-to-face counselling, telephone support, self-help materials (digital and printed), and complementary medicine.

Results

A total of 60.3% of smokers used aids in the past year, compared with just 14.9% of high-risk drinkers. Use of pharmacotherapy was high among smokers and very low among drinkers (56.0%_versus1.2%). Use of other aids was low for both behaviours: face-to-face counselling (2.6%_versus4.8%), self-help materials (1.4%_versus4.1%) and complementary medicine (1.0%_versus0.5%). Use of aids was more common among smokers aged 25–54 compared with 16–24 year olds (25–34,OR_adj1.49,p = 0.012; 35–44,OR_adj1.93,p < 0.001; 35–44,OR_adj1.93,p < 0.001; 45–54,OR_adj1.66,p = 0.008), with cigarette consumption >10 relative to <1 (10–20,OR_adj2.47,p = 0.011; >20,OR_adj4.23,p = 0.001), and less common among ethnic minorities (OR_adj0.69,p = 0.026). For alcohol reduction, use of aids was higher among ethnic minority groups (OR_adj2.41;p = 0.015), and those of social-grade D/E relative to AB (OR_adj2.29,p = 0.012&OR_adj3.13,p < 0.001).

Conclusion

In England, the use of pharmacotherapy is prevalent for smoking cessation but not alcohol reduction. Other aids are used at a low rate, with face-to-face counselling being more common for alcohol reduction than smoking cessation.
