Effects of Internet-Based Cognitive Behavioral Therapy for Harmful Alcohol Use and Alcohol Dependence as Self-help or With Therapist Guidance: Three-Armed Randomized Trial

Digital cognitive-behavioral therapy for substance use: systematic review and meta-analysis of randomized controlled trials

Background: Prior meta-analyses have evaluated digital interventions for alcohol exclusively and alcohol/tobacco combined. These meta-analyses showed positive outcomes pertaining to alcohol and alcohol/tobacco combined. Yet questions remain pertaining to the effect of digital cognitive-behavioral therapy (CBT) on reducing alcohol and drug use.Objectives: The purpose of the meta-analysis was to determine the mean effect size, relative to control groups, of digital CBT, for posttest reductions in drug and/or alcohol use.Methods: The Preferred Reporting Items for Systematic Reviews and Meta-analyses criteria was used to guide this review and meta-analysis. Electronic databases (APA PsycArticles, Academic Search Complete, APA PsycInfo, CINAHL Complete, ERIC, MEDLINE, Psychology and Behavioral Sciences Collection, Social Sciences Full Text, Social Work Abstracts, SocINDEX), clinicaltrials.gov, reference lists were searched. The protocol was registered in PROSPERO (ID#: CRD42023471492). The CBT interventions included cognitive restructuring.Results: All but one of the effect sizes favored digital CBT (from -0.02 to -1.45). After the removal an outlier, a small, significant, random effects model Hedges' g summary effect of -0.23 (95% confidence interval: -0.32, -0.14, p < .0001) showed a reduction in substance use at the posttest, favoring digital CBT relative to the control group. A variety of control conditions were used; however, the effects sizes had minimal heterogeneity (k = 17, I2 = 5.34, Q = 16.9, p = .39). The funnel plot and Egger regression test intercept (0.01, p = .99) lacked publication bias.Conclusion: The meta-analytic findings suggest digital CBT is an efficacious treatment for reducing alcohol and drug use overall.

User Engagement With mHealth Interventions to Promote Treatment Adherence and Self-Management in People With Chronic Health Conditions: Systematic Review

BACKGROUND

There are numerous mobile health (mHealth) interventions for treatment adherence and self-management; yet, little is known about user engagement or interaction with these technologies.

OBJECTIVE

This systematic review aimed to answer the following questions: (1) How is user engagement defined and measured in studies of mHealth interventions to promote adherence to prescribed medical or health regimens or self-management among people living with a health condition? (2) To what degree are patients engaging with these mHealth interventions? (3) What is the association between user engagement with mHealth interventions and adherence or self-management outcomes? (4) How often is user engagement a research end point?

METHODS

Scientific database (Ovid MEDLINE, Embase, Web of Science, PsycINFO, and CINAHL) search results (2016-2021) were screened for inclusion and exclusion criteria. Data were extracted in a standardized electronic form. No risk-of-bias assessment was conducted because this review aimed to characterize user engagement measurement rather than certainty in primary study results. The results were synthesized descriptively and thematically.

RESULTS

A total of 292 studies were included for data extraction. The median number of participants per study was 77 (IQR 34-164). Most of the mHealth interventions were evaluated in nonrandomized studies (157/292, 53.8%), involved people with diabetes (51/292, 17.5%), targeted medication adherence (98/292, 33.6%), and comprised apps (220/292, 75.3%). The principal findings were as follows: (1) >60 unique terms were used to define user engagement; "use" (102/292, 34.9%) and "engagement" (94/292, 32.2%) were the most common; (2) a total of 11 distinct user engagement measurement approaches were identified; the use of objective user log-in data from an app or web portal (160/292, 54.8%) was the most common; (3) although engagement was inconsistently evaluated, most of the studies (99/195, 50.8%) reported >1 level of engagement due to the use of multiple measurement methods or analyses, decreased engagement across time (76/99, 77%), and results and conclusions suggesting that higher engagement was associated with positive adherence or self-management (60/103, 58.3%); and (4) user engagement was a research end point in only 19.2% (56/292) of the studies.

CONCLUSIONS

The results revealed major limitations in the literature reviewed, including significant variability in how user engagement is defined, a tendency to rely on user log-in data over other measurements, and critical gaps in how user engagement is evaluated (infrequently evaluated over time or in relation to adherence or self-management outcomes and rarely considered a research end point). Recommendations are outlined in response to our findings with the goal of improving research rigor in this area.

Navigating challenges and opportunities: perspectives on digital service development in substance use disorder treatment

BACKGROUND

Some people with substance use disorders (SUD) can experience multiple co-occurring social problems. Digital solutions have been developed to support effective and cost-effective social welfare and healthcare in addictions treatment. Given the varying severity of problems from alcohol and other drug use, digital service tools can save money and provide tailored care.

OBJECTIVE

In this study we aimed to understand the perspectives of those who develop digital service tools on people with SUD and treatment encounters. As a case, we interviewed those who have been involved in the development of a digital client segmentation tool The Navigator.

METHODS

Ten (N = 10) semi-structured interviews were conducted with professionals involved in digital client segmentation tool development and were analysed with inductive content analysis. Participants were asked about the development of the Navigator from the perspectives of their own role as developers, the clients, the effectiveness of the services, and decision-making processes.

FINDINGS

Some people with SUD may face several obstacles when using digital services. Digital divide, feared or experienced stigma and biased attitudes, complex life situations, and difficulties in committing to treatment were identified as challenges. Nevertheless, digital solutions can offer the clients alternative ways of using the services that can better meet their individual needs. The anonymity and facelessness of digital solutions can reduce the fear of immediate judgement. Implementing digital solutions in substance use work poses challenges due to chronic staff shortages. Digitalisation often results in the creation of multiple simultaneously managed channels, potentially reducing time-consumption but increasing the perceived workload. There is a call for multi-professionalism, acknowledging inequalities between various disciplines within the field.

An Observational Study of a Digital Substance Use and Recovery Program

OBJECTIVE

Digital substance use treatment programs present an opportunity to provide nonresidential care for people with problematic substance use. In June 2021, the provincial government in Ontario provided free access to Breaking Free Online (BFO), a digital behavioral change program for people with substance use disorders.

METHODS

An observational study was conducted with retrospective data to characterize clients' use and engagement patterns in BFO and examine changes in self-reported outcomes.

RESULTS

In total, 6,370 individuals registered for BFO between June 2021 and October 2022, of whom 3,650 completed the intake assessment. Most of these clients were self-referred (64%), with 37% having been referred by health service providers. More than one-half of the clients (52%) resided in Ontario West or East regions. Support for addressing problematic alcohol use was the most requested program (40%). By October 2022, about 44% of the clients had completed between one and four of 12 program strategies. Analysis revealed significant changes in pre-post scores across four validated scales (p<0.001), indicating a decrease in anxiety and depression, an increase in quality of life, an improvement in recovery progression, and a decrease in severity of symptoms associated with substance use disorders.

CONCLUSIONS

BFO clients with higher completion rates had the most improvement across the scales used; however, clients with lower and medium completion rates also had improvements. Because of the shame and stigma associated with substance use, digital supports with low barriers to entry can help support the autonomy, privacy, and preferences of individuals seeking help for problematic substance use.

Effectiveness of proactive video therapy for problematic alcohol use on treatment initiation, compliance, and alcohol intake: a randomised controlled trial in Denmark

BACKGROUND

Few people with problematic alcohol use reach treatment and dropout is frequent. Therapy for problematic alcohol use delivered via video conference (e-alcohol therapy) might overcome treatment barriers. In this randomised study, we tested whether proactive e-alcohol therapy outperformed face-to-face alcohol therapy (standard care) regarding treatment initiation, compliance, and weekly alcohol intake at 3-month and 12-month follow-up.

METHODS

In this two-arm randomised controlled trial, we recruited individuals who had problematic alcohol use, defined as a score of 8 or more on the Alcohol Use Disorders Identification Test; were 18 years or older; and had access to a personal computer, smartphone, or tablet with internet access in Denmark through online advertisements. Participants were assigned to receive alcohol therapy delivered either face-to-face or via video conference. The number, frequency, and duration of therapy sessions were individualised in both groups. Data analysis was conducted using masked data. Primary analyses were based on an intention-to-treat sample. The study is registered with ClinicalTrials.gov (NCT03116282).

FINDINGS

Between Jan 22, 2018, and June 29, 2020, 816 individuals signed up for the trial and 502 (63%) were assessed for eligibility. We randomly assigned 379 to proactive e-alcohol therapy (n=187) or standard care (n=192), of which, 170 (48%) participants were female and 186 (52%) were male. In the intervention group, more participants initiated treatment (155 [88%] of 177 vs 96 [54%] of 179; odds ratio [OR] 6·3; 95% CI 2·8 to 13·8; p<0·0001 at 3 months; 151 [85%] of 177 vs 115 [64%] of 179; OR 3·2; 95% CI 1·6 to 6·2; p=0·0007 at 12 months) and complied with treatment (130 [73%] of 177 vs 74 [41%] of 179; OR 4·0; 95% CI 2·2 to 7·2; p<0·0001 at 3 months; 140 [79%] of 177 vs 95 [53%] of 179; OR 3·4; 95% CI 1·8 to 6·3; p=0·0002 at 12 months). Weekly alcohol intake was significantly lower in the intervention group only after 3 months (13·0 standard drinks per week vs 21·3 standard drinks per week; adjusted difference -6·7; 95% CI -12·3 to -1·0; p=0·019).

INTERPRETATION

Proactive e-alcohol therapy was associated with increased treatment initiation and compliance and is promising as an easily accessible and effective alcohol treatment for individuals with problematic alcohol use.

Internet-delivered therapy for alcohol misuse: engagement, satisfaction, and outcomes when patients select their preference for therapist- or self-guided treatment

BACKGROUND

Alcohol misuse is common and causes substantial harm. Internet-delivered cognitive behaviour therapy (ICBT) is effective in reducing alcohol misuse; however, the literature investigating how treatment outcomes are impacted by patients' preferences for therapist- versus self-guided ICBT for alcohol misuse is sparse.

METHODS

In this preference trial, 74 eligible patients (who reported ≥ 14 drinks in the previous week and obtained scores suggesting hazardous or harmful drinking) chose between enrolling in either therapist- or self-guided ICBT for alcohol misuse. We investigated whether those who chose therapist- versus self-guided ICBT differed in their (a) drinking outcomes-as measured by Timeline Follow-Back (TLFB) and heavy drinking days (HDD) at post-treatment and 3-month follow-up-and (b) post-treatment ICBT engagement and satisfaction.

RESULTS

The majority (81.1%) of eligible patients chose therapist-guided ICBT. These patients reported higher psychotropic medication use, drinking difficulties, and anxiety symptoms. For both the therapist- and self-guided patients, a modified intention-to-treat analysis revealed large within-group treatment effects for TLFB (β =  - 2.64, SE 0.66; p < 0.001) and HDD (β =  - 0.34, SE 0.07; p < 0.001), with large pre-to-post-treatment Cohen's effect sizes of d = 0.97 (95% CI [0.49, 1.45]) for TLFB and d = 1.19 (95% CI [0.69, 1.68]) for HDD. The interaction comparing the effects of therapist- to self-guided ICBT over time was not significant for TLFB (p = 0.34) or HDD (p = 0.06). With treatment, for both therapist- and self-guided patients, there was a significant improvement in drinking difficulties, cravings, and confidence with controlling cravings, as well as in anxiety, depression, and functional impairment. Further, the majority (75.7%) of patients completed five or more lessons, as well as reported overall satisfaction with the treatment (88.9%) and increased confidence in managing their symptoms (86.7%); these outcomes also did not differ between therapist- and self-guided patients.

CONCLUSIONS

The current study shows that ICBT for alcohol misuse is associated with reduced drinking and comorbid mental health difficulties over time, irrespective of whether patients chose to complete the course on their own or with therapist guidance.

Investigating the added effects of guidance in digital psychological self-care for alcohol problems (ALVA)-protocol for a randomized factorial optimization trial

BACKGROUND

The continual development and implementation of effective digital interventions is one important strategy that may serve to bridge the well-known treatment gap related to problematic alcohol use. Research suggests that clinician guidance, provided in different ways during the digital intervention (i.e., written weekly messages, phone calls etc.), can boost intervention engagement and effects. Digital psychological self-care (DPSC) is a new delivery format wherein an unguided digital intervention is provided within the framework of a structured care process that includes initial clinical assessment and follow-up interviews. In a recent feasibility study, a DPSC intervention for problematic alcohol use, ALVA, provided without any extra guidance, was found safe and credible and to have promising within-group effects on alcohol consumption. The aim of the current study is to gather information on the effects and efficiency of different forms of guidance added to ALVA, in order to optimize the intervention.

METHODS

This protocol describes a randomized factorial trial where the effects of two different ways of providing guidance (mid-treatment interview, weekly written messages, respectively) in DPSC for problematic alcohol use are investigated. Optimization criteria will be applied to the results regarding how effective the intervention is at reducing alcohol consumption measured by the number of standard drinks per week together with the clinician time spent on guidance.

DISCUSSION

This study will investigate the added benefit of different forms of guidance to DPSC for problematic alcohol use. These added effects will be compared to the added cost of guidance, according to pre-defined optimization criteria.

Digital interventions targeting excessive substance use and substance use disorders: a comprehensive and systematic scoping review and bibliometric analysis

Addictive substances are prevalent world-wide, and their use presents a substantial and persistent public health problem. A wide range of digital interventions to decrease use and negative consequences thereof have been explored, differing in approach, theoretical grounding, use of specific technologies, and more. The current study was designed to comprehensively map the recent (2015-2022) extant literature in a systematic manner, and to identify neglected and emerging knowledge gaps. Four major databases (Medline, Web of Science Core Collection, and PsychInfo) were searched using database-specific search strategies, combining terms related to clinical presentation (alcohol, tobacco or other drug use), technology and aim. After deduplication, the remaining n=13,917 unique studies published were manually screened in two stages, leaving a final n=3,056 studies, the abstracts of which were subjected to a tailored coding scheme. Findings revealed an accelerating rate of publications in this field, with randomized trials being the most common study type. Several meta-analyses on the topic have now been published, revealing promising and robust effects. Digital interventions are being offered on numerous levels, from targeted prevention to specialized clinics. Detailed coding was at times made difficult by inconsistent use of specific terms, which has important implications for future meta-analyses. Moreover, we identify several gaps in the extant literature - few health economic assessments, unclear descriptions of interventions, weak meta-analytic support for some type of interventions, and limited research on many target groups, settings and new interventions like video calls, chatbots and artificial intelligence - that we argue are important to address in future research.

Digital interventions for reducing alcohol use in general populations: An updated systematic review and meta-analysis

This article updates a 2017 review on the effectiveness of digital interventions for reducing alcohol use in the general population. An updated systematic search of the MEDLINE database was performed in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria to identify randomized controlled trials (RCTs) published from January 2017 to June 2022 that evaluated the effectiveness of digital interventions compared with no interventions, minimal interventions, and face-to-face interventions aimed at reducing alcohol use in the general population and, that also reported changes in alcohol use (quantity, frequency, quantity per drinking day, heavy episodic drinking (HED), or alcohol use disorders identification test (AUDIT) scores). A secondary analysis was performed that analyzed data from RCTs conducted in students. The review was not preregistered. The search produced 2224 articles. A total of 80 studies were included in the review, 35 of which were published after the last systematic review. A total of 66, 20, 18, 26, and 9 studies assessed the impact of digital interventions on alcohol quantity, frequency, quantity per drinking day, HED, and AUDIT scores, respectively. Individuals randomized to the digital interventions drank 4.12 (95% confidence interval (CI): 2.88, 5.36) fewer grams of alcohol per day, had 0.17 (95% CI 0.06, 0.29) fewer drinking days per week, drank approximately 3.89 (95% CI: 0.40, 7.38) fewer grams of alcohol per drinking day, had 1.11 (95% CI: 0.32, 1.91) fewer HED occasions per month, and had an AUDIT score 3.04 points lower (95% CI: 2.23, 3.85) than individuals randomized to the control condition. Significant reductions in alcohol quantity, frequency, and HED, but not quantity per drinking day, were observed among students. Digital interventions show potential for reducing alcohol use in general populations and could be used widely at the population level to reduce alcohol-attributable harms.

High- versus low-intensity internet interventions for alcohol use disorders (AUD): A two-year follow-up of a single-blind randomized controlled trial

Alcohol Use Disorders (AUD) are widespread and have serious consequences, but are among the most undertreated mental disorders. Internet interventions have been found effective in treating AUD, but we know little about long-term outcomes, two years or more after treatment. This study explored 12- and 24-month outcomes in alcohol consumption following initial 6-month improvements after a therapist-guided high-intensity internet intervention and an unguided low-intensity internet intervention among individuals with alcohol use disorder. Between-group comparisons were analyzed, as well as within-group comparisons with (1) pre-treatment measurements (2) post-treatment measurements. Participants consisted of a general population sample of internet help-seekers in Sweden. A total of 143 adults (47% men) with a score of 14 (women)/16 (men) or more on the Alcohol Use Disorders Identification Test, alcohol consumption of 11 (women)/14 (men) or more standard drinks the preceding week and ≥ 2 DSM-5 alcohol use disorder (AUD) criteria based on a diagnostic interview were included. The high- and low-intensity internet interventions (n = 72 and n = 71 respectively) consisted of modules based on relapse prevention and cognitive-behavioral therapy. The primary outcome was self-reported alcohol consumption in the preceding week measured as (1) number of standard drinks and (2) number of heavy drinking days. Attrition from self-reported questionnaires was 36% at the 12-month follow-up and 53% at the 24-month follow-up. No significant between-group differences occurred in outcomes at either long-term follow-up. Regarding within-group differences, compared to pre-treatment, alcohol consumption was lower in both high- and low-intensity interventions at both long-term follow-ups [within-group standard drinks effect sizes varied between g = 0.38-1.04 and heavy drinking days effect sizes varied between g = 0.65-0.94]. Compared to post-treatment, within-group alcohol consumption in the high intensity intervention increased at both follow-ups; for the low-intensity intervention, within-group consumption decreased at 12-month follow-up, but did not differ compared to post-treatment at 24 months. Both high- and low-intensity internet interventions for AUD were thus associated with overall reductions in alcohol consumption at long term follow-ups, with no significant differences between the two. However, conclusions are hampered by differential and non-differential attrition.

Evaluation of a Primary E-Health Intervention for People with Alcohol Use Disorder: Clinical Characteristics of Users and Efficacy

In Germany, only about 10% of patients with alcohol use disorder (AUD) are treated by the professional help system. "The First 30 Days without Alcohol", an interactive e-health intervention, was developed to support people with "alcohol problems" to abstain from alcohol. The aim of this study was to examine the feasibility of the approach, the program's target group, if and why it is effective. In March 2022 an email was sent to all users who had completed the program. A link to a web-based survey regarding the target group's characteristics, its alcohol-use patterns, former attempts to change the problematic drinking behavior and experience with the program was introduced. The Alcohol Use Disorders Identification Test (AUDIT) was used prior and post intervention. A total of 718 participants completed the questionnaire. Of these, 99.2% suffered from AUD; 81.6% of participants were females, and about one third reported some form of psychiatric comorbidity; 46.6% did not use any additional help or assistance apart from the program; 78.3% reported to be abstinent after participation in the 30-day program, and the data show a significant AUDIT score reduction. Primary e-health interventions may contribute to the established addiction-help system. The intervention seems to reach predominantly highly educated and high-functioning females because of their characteristics.

Digital psychological self-care for problematic alcohol use: feasibility of a new clinical concept

BACKGROUND

Digital interventions based on cognitive-behavioural therapy and relapse prevention can increase treatment access for people with problematic alcohol use, but for these interventions to be cost-effective, clinician workload needs to remain low while ensuring patient adherence and effects. Digital psychological self-care is the provision of a self-guided digital intervention within a structured care process.

AIMS

To investigate the feasibility and preliminary effects of digital psychological self-care for reducing alcohol consumption.

METHOD

Thirty-six adults with problematic alcohol use received digital psychological self-care during 8 weeks, including telephone assessments as well as filling out self-rated questionnaires, before, directly after and 3 months after the intervention. Intervention adherence, usefulness, credibility and use of clinician time were assessed, along with preliminary effects on alcohol consumption. The study was prospectively registered as a clinical trial (NCT05037630).

RESULTS

Most participants used the intervention daily or several times a week. The digital intervention was regarded as credible and useful, and there were no reported adverse effects. Around 1 h of clinician time per participant was spent on telephone assessments. At the 3-month follow-up, preliminary within-group effects on alcohol consumption were moderate (standardised drinks per week, Hedge's g = 0.70, 95% CI = 0.19-1.21; heavy drinking days, Hedge's g = 0.60, 95% CI = 0.09-1.11), reflecting a decrease from 23 to 13 drinks per week on average.

CONCLUSIONS

Digital psychological self-care for reducing alcohol consumption appears both feasible and preliminarily effective and should be further optimised and studied in larger trials.

Psychosocial and Pharmacological Therapies to Reduce Alcohol Consumption in Severe Alcohol-Related Hepatitis Patients: A Case Report

Alcohol-related hepatitis (ARH) is an inflammatory liver disease caused by excessive alcohol intake over time. This represents a major health burden with a high mortality and poor prognosis. Reducing alcohol consumption is key to improving health outcomes and long-term mortality. Therefore, various measures have been implemented to aid in the reduction of alcohol consumption. On a population level, this includes minimum unit pricing to reduce alcohol purchases. On a patient level, evidence-based psychosocial and pharmacological therapies aid in achieving and maintaining alcohol abstinence, which will be explored through this case report. A 39-year-old male with a four-year history of alcohol excess was admitted to a regional hospital. He presented with acute onset jaundice and examination findings were consistent with signs of chronic liver disease including abdominal distension and confusion. Investigations supported a diagnosis of severe ARH in this alcohol-dependent patient. Upon discharge, the patient received regular online cognitive behavioral therapy (CBT) sessions to aid in his abstinence. Psychosocial therapy for alcohol abstinence can be categorized into brief and extended interventions. Brief interventions are short counseling sessions, which may be most effective in non-alcohol-dependent patients, whereas extended therapies including CBT, motivational enhancement therapy, and 12-step facilitation are longer regular therapies that may be more effective for alcohol-dependent patients. Some pharmacotherapies are contraindicated in ARH patients due to their hepatotoxicity and liver metabolism. However, acamprosate and baclofen are appropriate and effective treatments. Combining psychosocial and pharmacological therapy may be more beneficial than individual treatments to achieve and maintain abstinence.

[Acceptance and use of web-based interventions for alcohol abstinence]

INTRODUCTION

In Germany, the prevalence rates for alcohol use disorders amount to approx. 6%, while about 3% are diagnosed as being alcohol dependent. Only 10% of the patients are undergoing treatment. There are apparent deficits with respect to early interventions. The internet presence of "Ohne Alkohol mit Nathalie" (OAmN) (Abstinence with Nathalie) ameliorates options for early treatment interventions using a web-based design; however, this intervention has not been evaluated to date, especially with respect to previous treatments.

METHODS

Over a 4-week period, 4 different channels of OAmN posted announcements for a survey participation introducing a link leading to a web-based survey questionnaire on the domain oamn.jetzt. The questionnaire offered open and closed as well as multiple choice questions regarding alcohol use patterns and attempts to change the problematic drinking behavior.

RESULTS

Out of 2022 participants 84.3% (n = 1705) stated to have or have had a problem with alcohol use, 17.7% (n = 302) had a diagnosis of alcohol dependence by a physician or psychologist and only 21% (n = 529) had been in therapy before. The majority of responders (85.5%, n = 1457) had stopped alcohol use before participating in the survey. Most of them (48.5%, n = 705) were assisted by OAmN, 97.5% (n = 1662) had been employed while having the abovementioned problem use of alcohol, 34.3% (n = 570) rated their job performance as "very good" and 43.2% (n = 718) as "good".

DISCUSSION

This pilot study revealed that OAmN can reach people affected by problematic drinking behavior who had not been in contact with the professional medical system for addiction treatment despite having a problematic alcohol use combined with the willingness to quit.

Experiences of a therapist-guided internet-delivered intervention for hazardous and harmful drinking. A qualitative study

BACKGROUND

Alcohol is the third leading risk factor for burden of disease in the world, causing significant health damage to the individual as well as costs to the surroundings and society as whole. Internet-delivered psychological interventions may help the individual to address alcohol consumption at an early stage before it develops into more serious problems. There is a need to investigate how participants experience internet-delivered interventions for hazardous and harmful drinking to optimize its usefulness in the target population.

METHODS

The present study was part of an open pre-post pilot trial to evaluate the feasibility and acceptability of a therapist-guided internet-delivered cognitive behavioural intervention for hazardous and harmful alcohol use. The aim was to investigate participants` experiences of the intervention and the ways in which the intervention helped them to address their alcohol consumption. Fifteen participants were selected from the open pre-post trial (n = 32), and semi-structured interviews were conducted immediately after participants had completed the treatment. The interviews were analysed using Thematic Analysis.

RESULTS

The results indicate that most of the participants found the intervention to be useful. Participants reported that the intervention made them more aware of the consequences of excessive drinking and gave them tools to cope with their alcohol consumption. Among the perceived advantages were the flexibility and anonymity of the intervention and therapist support. Participants called for more individualisation of the treatment to meet individual needs.

CONCLUSIONS

A therapist-guided internet-delivered intervention for hazardous and harmful drinking can help individuals to address their alcohol consumption and give them tools to cope with their drinking. Future studies should examine the feasibility of tailoring modules to individual needs.

Effectiveness of guided and unguided online alcohol help: A real-life study

AIMS

Online interventions reduce the treatment gap between the number of people with alcohol misuse and people who actually receive help. This study investigated the effectiveness and predictors of success of a Belgian online help programme.

METHODS

A real-life retrospective open cohort study evaluating the guided and unguided internet intervention on the Belgian online platform alcoholhulp.be. The intervention consisted of a 12-week programme based upon cognitive behaviour therapy, motivational interviewing and acceptance and commitment therapy. Inclusion criteria are age above 18 years, recording of alcohol consumption in the daily journal for at least 2 weeks, and minimum 2 chat sessions in the guided group.Outcomes were weekly alcohol consumption after 6 and 12 weeks and treatment response (drinking less than 10 or 20 standard units (SU) per week). Additional analysis was done on predictors of success.

RESULTS

A total of 460 participants in the guided group and 968 in the self-help group met the inclusion criteria. Average baseline alcohol consumption in the two groups was 40 SU per week. Alcohol consumption decreased by 31 SU (Cohen's d 1.17, p < 0.001) after 12 weeks in the guided group and 23 SU (Cohen's d 0.83, p < 0.001) in the self-help group. The treatment response below 20 SU per week was 88% for the guided group and 73% for the self-help group. Significantly better results were obtained in the guided group compared to the self-help group (p < 0.005). Participants with a higher baseline alcohol consumption had a higher decrease in alcohol consumption in both groups. The personal goal to quit, the absence of drug use, a lower baseline alcohol consumption and a higher number of completed assignments predict a higher chance of treatment response. Attrition at 6 weeks was 26% in the guided group and 63% in the self-help group and increased to 59% and 82% respectively at 12 weeks.

CONCLUSIONS

Both guided and unguided internet interventions are effective in reducing alcohol consumption and achieving the guideline for participants motivated to use the platform on a regular base, with better results in guided intervention.

Repetitive transcranial magnetic stimulation combined with cognitive behavioral therapy treatment in alcohol-dependent patients: A randomized, double-blind sham-controlled multicenter clinical trial

BACKGROUND

Alcohol dependence (AD) is a complex addictive disorder with a high relapse rate. Previous studies have shown that both repetitive transcranial magnetic stimulation (rTMS) and cognitive behavioral therapy (CBT) may be effective for AD, and we aim to explore more effective treatment options to reduce relapse rates for AD.

MATERIALS AND METHODS

A total of 263 AD patients were recruited. They were divided into six groups according to the location and the type of rTMS: left dorsolateral prefrontal cortex (DLPFC), right DLPFC, sham stimulation, and whether they received CBT treatment: with a fixed schedule (C1) and without a fixed plan (C0). There were included in sham rTMS + C0 group (n = 50), sham rTMS + C1 group (n = 37), right rTMS + C0 group (n = 45), right rTMS + C1 group (n = 42), left rTMS + C0 group (n = 49), left rTMS + C1 group (n = 40). We used obsessive compulsive drinking scale (OCDS), visual analogue scale (VAS), alcohol dependence scale (ADS), montreal cognitive assessment (MoCA), generalized anxiety disorder-7 (GAD-7), patient health questionnaire-9 items (PHQ-9), and Pittsburgh sleep quality index (PSQI) to assess alcohol cravings, alcohol dependence, cognition, anxiety, depression, and sleep quality. They were followed up and evaluated for relapse.

RESULTS

The sham rTMS + C0 group relapse rate was significantly higher than the right rTMS + C1 group (P = 0.006), the left rTMS + C0 group (P = 0.031), the left rTMS + C1 group (P = 0.043). The right rTMS + C0 group showed significantly higher relapse rate compared to the right rTMS + C1 group (P = 0.046). There was no significant difference in relapse rates between other groups. The repeated-measures ANOVA showed an interaction effect between group and time was significant in the rate of patient health questionnaire-9 items (PHQ-9) scale reduction (P = 0.020). Logistic analysis indicated that smoking and alcohol consumption were independent determinants of relapse (P < 0.05). At 24 weeks of follow-up, Kaplan-Meier survival analysis reveal that there is statistically significant relapse rate between six groups (P = 0.025), left rTMS + C1 group has the best treatment effect for alcohol dependent patients. Cox regression analysis confirmed that current smoking, total cholesterol, and total bilirubin (TBIL) level were risk factors of relapse (P < 0.05).

CONCLUSION

This study is the first to suggest that the combination of rTMS and CBT may be a potentially effective treatment for reducing relapse.

Impact of Users' Attitudes Toward Anonymous Internet Interventions for Cannabis vs. Alcohol Use: A Secondary Analysis of Data From Two Clinical Trials

Background: Numerous trials have demonstrated the efficacy of internet interventions targeting alcohol or cannabis use, yet a substantial proportion of users do not benefit from the format, warranting further research to identify moderators of treatment effects. Users' initial attitudes toward treatment is a potential moderator, yet no previous study has investigated users' attitudes in the context of internet interventions for addictive disorders. Method: In this secondary analysis on two internet-based trials targeting harmful alcohol use (n = 1,169) and regular cannabis use (n = 303), respectively, we compared user groups' attitudes at the item level; explored within-group heterogeneity by submitting attitude scores to a k-means cluster analysis; and investigated whether latent subgroups in each user group moderated the treatment effects. Outcome models were run using generalized linear models with 10,000 bias-corrected bootstraps accounting for subject-level clustering. Results: While substance groups and latent subgroups converged in enjoying the anonymity provided by the format, their interest toward treatment differed. Outcome analyses revealed a significant and negative time by subgroup effect on grams of cannabis consumed and screening test score (CAST), favoring the subgroup with positive treatment attitudes. There were not any significant effects of subgroup on alcohol consumption. Despite initial treatment reluctance, participants in the neutral subgroup decreased their cannabis use (gram) significantly when receiving the intervention vs. control. Conclusions: This first, exploratory study revealed key differences between substance groups' attitudes, but more importantly that within-group heterogeneity appear to affect cannabis outcomes. Assessing attitudes could be key in patient-treatment matching, yet more research is needed.
