Efficacy of a web-based intervention with and without guidance for employees with risky drinking: results of a three-arm randomized controlled trial

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.

Digital Alcohol Interventions Could Be Part of the Societal Response to Harmful Consumption, but We Know Little About Their Long-Term Costs and Health Outcomes

Alcohol consumption causes both physical and psychological harm and is a leading risk factor for noncommunicable diseases. Digital alcohol interventions have been found to support those looking for help by giving them tools for change. However, whether digital interventions can help tackle the long-term societal consequences of harmful alcohol consumption in a cost-effective manner has not been adequately evaluated. In this Viewpoint, we propose that studies of digital alcohol interventions rarely evaluate the consequences of wider dissemination of the intervention under study, and that when they do, they do not take advantage of modeling techniques that allow for appropriately studying consequences over a longer time horizon than the study period when the intervention is tested. We argue that to help decision-makers to prioritize resources for research and dissemination, it is important to model long-term costs and health outcomes. Further, this type of modeling gives important insights into the context in which interventions are studied and highlights where more research is required and where sufficient evidence is available. The viewpoint therefore invites the researcher not only to reflect on which interventions to study but also how to evaluate their long-term consequences.

Precision computerised cognitive behavioural therapy (cCBT) for adolescents with depression: a pilot and feasibility randomised controlled trial protocol for SPARX-UK

BACKGROUND

A serious game called SPARX (Smart, Positive, Active, Realistic, X-factor thoughts), originally developed in New Zealand and incorporating cognitive behavioural therapy (CBT) principles, has been shown to help reduce symptoms of depression and anxiety in adolescents with mild to moderate depression in studies undertaken in Australasia. However, SPARX has never been trialled in the United Kingdom (UK), and there have been issues relating to low engagement when it has been used in a real-world context.

AIMS

To conduct the first pilot and feasibility randomised controlled trial (RCT) in England to explore the use of SPARX in different settings. The trial will explore whether SPARX supported by an e-coach (assistant psychologists) improves adherence and engagement compared with self-directed (i.e. self-help) use. The trial results will be used to inform the optimal mode of delivery (SPARX supported vs. SPARX self-directed), to calculate an appropriate sample size for a full RCT, and to decide which setting is most suitable.

METHODS

Following consultation with young people to ensure study suitability/appropriateness, a total of 120 adolescents (11-19 years) will be recruited for this three-arm study. Adolescents recruited for the study across England will be randomised to receive either SPARX with human support (from an e-coach), self-directed SPARX, or a waitlist control group. Assessments will be conducted online at baseline, week 4, and 8-10-week post-randomisation. The assessments will include measures which capture demographic, depression (Patient Health Questionnaire modified for adolescents [PHQ-A]) and anxiety (Revised Child Anxiety and Depression Scale [RCADS]) symptomatology, and health-related quality-of-life data (EQ-5D-Y and proxy version). Analyses will be primarily descriptive. Qualitative interviews will be undertaken with a proportion of the participants and clinical staff as part of a process evaluation, and the qualitative data gathered will be thematically analysed. Finally, feasibility data will be collected on recruitment details, overall study uptake and engagement with SPARX, participant retention, and youth-reported acceptability of the intervention.

DISCUSSION

The findings will inform the design of a future definitive RCT of SPARX in the UK. If the subsequent definitive RCT demonstrates that SPARX is effective, then an online serious game utilising CBT principles ultimately has the potential to improve the provision of care within the UK's health services if delivered en masse.

The effectiveness of workplace interventions for the prevention of alcohol use: A meta-analysis

BACKGROUND AND AIMS

Previous research has pointed to the potential of workplace interventions addressing alcohol consumption. However, there is still no systematic overview of the effects of these interventions. Therefore, we aimed to quantify the effectiveness of workplace interventions addressing alcohol use by conducting a meta-analysis.

METHODS

A systematic literature search for randomized controlled trials of workplace alcohol interventions published between 1995 and 2020 was conducted in five databases. Studies were included if they were performed in the workplace and reported universal or selective interventions aiming for alcohol use reduction. Primary outcomes were any measures of alcohol use. Standardized mean effect sizes were used to calculate the meta-analytic random-effects-model. Additional analyses were carried out to identify potential moderators and to examine the amount of heterogeneity and publication bias.

RESULTS

Twenty studies with 4484 participants were integrated into the meta-analysis. Results revealed a significant overall mean effect indicating a reduction of alcohol use in favor of the treatment group (d = -0.16, 95% CI = [-0.2715; -0.0511]). Heterogeneity within the data structure was found to be moderate to substantial (I2  = 75.9%, Q-test P < 0.001, τ2 = 0.0375). Additional moderator analyses only showed a significant effect for length of measurement period (P = 0.049).

CONCLUSIONS

Alcohol-related prevention programs conducted in the workplace have a statistically significant and favorable effect on alcohol consumption. Although the overall mean effect is considered to be small, it underlines the effectiveness of workplace interventions targeting a reduction in alcohol use.

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.

"Online, the counselor can't see me cry": a systematic literature review on emotion and computer-mediated care

Introduction

Computer-mediated care is becoming increasingly popular, but little research has been done on it and its effects on emotion-related outcomes. This systematic literature review aims to create an overview that addresses the research question: "Is there a relationship between computer-mediated care and emotional expression, perception, and emotional and (long-term) emotion outcomes?"

Method

This systematic literature review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines and used five eligibility criteria, namely, (1) participants: adults seeking support; (2) intervention: eHealth; (3) diagnostic criteria: transdiagnostic concept of difficulty identifying, expressing, and/or regulating emotions (e.g., alexithymia); (4) comparator: either face-to-face care or no comparator; and (5) study design: quantitative studies or qualitative studies. Quality was assessed using the QualSyst tool.

Results

The analysis includes 25 research papers. Self-paced interventions appear to have a positive effect on emotion regulation. Videoconferencing interventions improved emotion regulation from before to after treatment but worsened emotion regulation compared with face-to-face treatment.

Discussion

The lack of variation in the modalities studied and the emotion measurements used make it difficult to draw responsible conclusions. Future research should examine how different modalities affect the real-time communication of emotions and how non-verbal cues influence this.

User profile of an online cognitive behavioral therapy self-help platform in Turkey

Online mental health self-help services are of societal importance and increasingly popular. Therefore, we have developed an online platform offering free self-help to the Turkish public with modules based on Cognitive Behavioral Therapy (CBT) targeting depression, anxiety, and stress respectively. The main purpose of this study is to describe the user profile of this platform. A pre-intervention self-report assessment including general demographic information and the Brief Symptom Inventory questionnaire during October 2020 until September 2022. 8331 participants completed the assessment and created an account out of the 11.228 users who registered during a two-year period, of which 8.331 (74%) completed the assessment and created an account. The majority of these users were female (76.17%), highly educated (82%), single (68%) and actively studying or working (84%). Slightly more than half (57%) of the platform user had not received psychological assistance before, while those who did receive previous assistance indicate to have benefitted from that (74%). The psychological symptoms of users are widely distributed, encompassing a broad range of user profiles. Approximately half of all users actively used the platform, while the other half did not complete any module. Among active users, the course "coping with depressive mood" was the most popular (41.45%), followed by "coping with anxiety" (37.25%) and "coping with stress" (21.30%). Offering a free online CBT self-help platform to the Turkish public seems feasible, with strong uptake among both man and woman struggling with a variety of psychological symptoms. Further research is needed to assess user satisfaction and change in symptoms over time during platform use by means of a feasibility trial.

What do we know about alcohol internet interventions aimed at employees?-A scoping review

Background

Internet interventions are a promising avenue for delivering alcohol prevention to employees. The objective of this scoping review was to map all research on alcohol internet interventions aimed at employees regardless of design, to gain an overview of current evidence and identify potential knowledge gaps.

Methods

We conducted a literature search in three data bases (PsycInfo, PubMed, and Web of Science). Eligibility criteria were that (1) the study targeted employees age ≥18 years; (2) the intervention was delivered predominantly online; (3) the study focused specifically or in part on alcohol use; and (4) the study was published in English in a peer-reviewed academic journal. Two reviewers independently screened, reviewed, and extracted data.

Results

Twenty studies were included, of which 10 were randomized controlled trials, five were secondary analyses, three were feasibility trials, one was a cohort study and one described the rationale and development of an intervention. No qualitative studies were found. Randomized trials tended to show effects when interventions were compared to waitlists but not when more intensive interventions were compared to less intensive ones. We identified two design-related aspects where studies differed; (1) whether all applicants were included regardless of alcohol use level and (2) whether the intervention was explicitly framed as alcohol-focused or not. Significant recruitment problems were noted in several studies.

Conclusions

Alcohol internet interventions hold promise in delivering alcohol prevention to employees, but heterogeneity in study design and difficulties in recruitment complicate interpretation of findings.

Optimizing internet-delivered cognitive behaviour therapy for alcohol misuse—a randomized factorial trial examining effects of a pre-treatment assessment interview and guidance

Background

Internet-delivered cognitive behavioral therapy (ICBT) for alcohol misuse has potential to radically improve access to evidence-based care, and there is a need to investigate ways to optimize its delivery in clinical settings. Guidance from a clinician has previously been shown to improve drinking outcomes in ICBT, and some studies suggest that pre-treatment assessments may contribute in initiating early change. The objective of this study was to investigate the added and combined effects of a pre-treatment assessment interview and guidance on the outcomes of ICBT for alcohol misuse delivered in an online therapy clinic.

Methods

A 2X2 factorial randomized controlled trial was conducted where participants received access to an 8-week ICBT program, and either a pre-treatment assessment interview (Factor 1), guidance (Factor 2), a combination of these, or neither of these. Participants were 270 individuals (66.8% female, mean age = 46.5) scoring 8 or more on the Alcohol Use Disorders Identification Test and consuming 14 standard drinks or more in the preceding week. Primary outcomes were number of drinks consumed and number of heavy drinking days during the preceding week, 3 months post-treatment.

Results

Large within-group effects were found in terms of alcohol reductions (d_w ≥ 0.82, p < 0.001), but neither of the factors significantly improved drinking outcomes. Guidance was associated with greater adherence (i.e. completed modules).

Conclusions

Neither a pre-treatment assessment interview nor guidance from a clinician appears to improve drinking outcomes resulting from internet-delivered cognitive behaviour therapy for alcohol misuse when delivered in a routine online therapy clinic.

Seeking care where they can: A systematic review of global trends in online alcohol treatment utilization among non-veteran and veteran women

Background

Findings from a person-level meta-analysis of online alcohol intervention trials suggest that women disproportionately seek out such interventions (Riper et al., 2018). Although women may be a "hidden population" that is particularly drawn to online alcohol interventions, trial design features may explain women's apparent over-representation in these trials.

Methods

This systematic review examined associations between gender-tailored recruitment/inclusion criteria and proportions of women enrolled in online alcohol intervention trials, evaluated whether community samples have greater proportions of women than clinical samples, and compared country-specific average proportions of women in trials to country-specific proportions of women with Alcohol Use Disorder (AUD).

Results

Forty-four trials met inclusion/exclusion criteria, 34 community samples and 10 drawn from clinical settings; 4 studies included U.S. veterans and were examined separately. The average proportion of community-recruited women across the studies was 51.20% and the average proportion of clinically-recruited women was 35.81%, a difference that was statistically significant. Across the countries with relevant trials, the expected proportion of those with AUD who are women is 27.1% (World Population Review, 2022). Only 2 studies used targeted recruitment for women so no between-group tests were conducted. There was not a statistically significant difference in the proportion of women across trials that did and did not use gender-tailored alcohol inclusion criteria.

Conclusions

Results from this systematic review suggest that study design factors do not account for the marked over-representation of women in online alcohol interventions, indicating that women are indeed a "hidden population" whose needs should be understood and accommodated.

A systematic review and behaviour change technique analysis of remotely delivered alcohol and/or substance misuse interventions for adults

BACKGROUND

There has been a lack of systematic exploration of remotely delivered intervention content and their effectiveness for behaviour change outcomes. This review provides a synthesis of the behaviour change techniques (BCT) contained in remotely delivered alcohol and/or substance misuse approaches and their association with intervention promise.

METHODS

Searches in MEDLINE, Scopus, PsycINFO (ProQuest), and the Cochrane Library, included studies reporting remote interventions focusing on alcohol and/or substance misuse among adults, with a primary behaviour change outcome (e.g., alcohol levels consumed). Assessment of risk of bias, study promise, and BCT coding was conducted. Synthesis focussed on the association of BCTs with intervention effectiveness using promise ratios.

RESULTS

Studies targeted alcohol misuse (52 studies) or substance misuse (10 studies), with predominantly randomised controlled trial designs and asynchronous digital approaches. For alcohol misuse studies, 16 were very promising, 17 were quite promising, and 13 were not promising. Of the 36 eligible BCTs, 28 showed potential promise, with seven of these only appearing in very or quite promising studies. Particularly promising BCTs were 'Avoidance/reducing exposure to cues for behaviour', 'Pros and cons' and 'Self-monitoring of behaviour'. For substance misuse studies, three were very promising and six were quite promising, with all 12 BCTs showing potential promise.

CONCLUSIONS

This review showed remotely delivered alcohol and substance misuse interventions can be effective and highlighted a range of BCTs that showed promise for improving services. However, concerns with risk of bias and the potential of promise ratios to inflate effectiveness warrant caution in interpreting the evidence.

Technology-Delivered Adaptations of Motivational Interviewing for the Prevention and Management of Chronic Diseases: Scoping Review

Background

Motivational interviewing (MI) can increase health-promoting behaviors and decrease health-damaging behaviors. However, MI is often resource intensive, precluding its use with people with limited financial or time resources. Mobile health–based versions of MI interventions or technology-delivered adaptations of MI (TAMIs) might increase reach.

Objective

We aimed to understand the characteristics of existing TAMIs. We were particularly interested in the inclusion of people from marginalized sociodemographic groups, whether the TAMI addressed sociocontextual factors, and how behavioral and health outcomes were reported.

Methods

We employed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines for scoping reviews to conduct our scoping review. We searched PubMed, CINAHL, and PsycInfo from January 1, 1996, to April 6, 2022, to identify studies that described interventions incorporating MI into a mobile or electronic health platform. For inclusion, the study was required to (1) describe methods/outcomes of an MI intervention, (2) feature an intervention delivered automatically via a mobile or electronic health platform, and (3) report a behavioral or health outcome. The exclusion criteria were (1) publication in a language other than English and (2) description of only in-person intervention delivery (ie, no TAMI). We charted results using Excel (Microsoft Corp).

Results

Thirty-four studies reported the use of TAMIs. Sample sizes ranged from 10 to 2069 participants aged 13 to 70 years. Most studies (n=27) directed interventions toward individuals engaging in behaviors that increased chronic disease risk. Most studies (n=22) oversampled individuals from marginalized sociodemographic groups, but few (n=3) were designed specifically with marginalized groups in mind. TAMIs used text messaging (n=8), web-based intervention (n=22), app + text messaging (n=1), and web-based intervention + text messaging (n=3) as delivery platforms. Of the 34 studies, 30 (88%) were randomized controlled trials reporting behavioral and health-related outcomes, 23 of which reported statistically significant improvements in targeted behaviors with TAMI use. TAMIs improved targeted health behaviors in the remaining 4 studies. Moreover, 11 (32%) studies assessed TAMI feasibility, acceptability, or satisfaction, and all rated TAMIs highly in this regard. Among 20 studies with a disproportionately high number of people from marginalized racial or ethnic groups compared with the general US population, 16 (80%) reported increased engagement in health behaviors or better health outcomes. However, no TAMIs included elements that addressed sociocontextual influences on behavior or health outcomes.

Conclusions

Our findings suggest that TAMIs may improve some health promotion and disease management behaviors. However, few TAMIs were designed specifically for people from marginalized sociodemographic groups, and none included elements to help address sociocontextual challenges. Research is needed to determine how TAMIs affect individual health outcomes and how to incorporate elements that address sociocontextual factors, and to identify the best practices for implementing TAMIs into clinical practice.

Digital prevention of depression for farmers? A qualitative study on participants' experiences regarding determinants of acceptance and satisfaction with a tailored guided internet intervention program

INTRODUCTION

Farmers, forest workers and gardeners have a higher risk of developing depression compared to other occupational populations. As part of the German pilot project "With us in balance", the potential of six guided internet- and mobile-based interventions (IMIs) to prevent depression among their insurants is examined. The IMI program is tailored to various risk factors of depression, individual symptoms, and needs. Although IMIs have been shown to be effective in reducing depressive symptoms, there is little qualitative research about the acceptance of digital preventive IMIs. The aim of this qualitative study is to gain insights into participants' experiences with the guided IMIs by focusing on determinants for acceptance and satisfaction.

METHODS

Semi-structured interviews were conducted with 22/171 (13 %) intervention group (IG) participants of a randomized controlled trial. The interview guide was developed based on theoretical models of user acceptance (Unified Theory of Acceptance and Use of Technology) and patient satisfaction (evaluation model, discrepancy theory). The interviews were evaluated independently by two coders performing a deductive-inductive content analysis and attaining a substantial level of agreement (K = 0.73).

RESULTS

The qualitative analysis revealed 71 determinants for acceptance and satisfaction across ten dimensions: performance expectancy, organisation, e-coach, usability, training content and structure, training usage, training outcome, financing, social influence, and behavioural intention. The most frequently identified drivers for the IMI use include "location independence", "positive relationship to the e-coach" (each n = 19, 86 %), "personal e-coach guidance", "expertise of the e-coach", "target group specific adaptation" (each n = 18, 82 %), "flexibility", "high willingness for renewed participation" (each n = 17, 77 %), "fast and easy availability", "training of health enhancing attitudes and behaviours" and "content with figurative expressions" (each n = 16, 73 %).

DISCUSSION

The qualitative findings predominantly suggest the acceptance of and satisfaction with the IMI program for the prevention of depression in famers and related lines of work. Many identified positive drivers are related to the e-coach guidance, which emphasizes its importance in the preventive setting from the perspective of the participants. Nevertheless, some negative aspects have been identified which help to understand potential weaknesses of the IMI program. Participants indicated different needs in terms of IMI content and usage, which points towards the potential benefit of individualisation. The possibility of being able to use IMIs anonymously, flexibly and independently of location might be highly relevant for this specific target group.

Evaluation of a workplace alcohol prevention program targeted on managers’ inclination to initiate early alcohol intervention

BACKGROUND: Alcohol interventions targeting the adult population are often conducted in healthcare settings, while preventive interventions often target adolescents or young adults. The general working population is often overlooked. A workplace-based intervention, consisting of development and implementation of an organizational alcohol policy, and skills development training for managers (APMaT) was carried out in order to prevent and reduce alcohol-related harms by identifying hazardous consumers at an early stage. OBJECTIVE: This study aims to evaluate APMaT by focusing on managers’ inclination to initiate early alcohol intervention. METHODS: In a cluster randomized design, data were obtained from 187 managers (control: n = 70; intervention: n = 117). Inclination to initiate early alcohol intervention was measured using three items on a 5-point Likert scale ranging from 1 (strongly disagree) to 5 (strongly agree). Changes in managers’ inclination to intervene were analyzed by applying multilevel ordered logistic regression. Predictors included in the model were group (control vs. intervention), time (baseline vs. 12-month follow-up), and the multiplicative interaction term (group×time). RESULTS: Significant increase in inclination to intervene against hazardous alcohol consumption among managers in the intervention group compared to managers in the control group was observed. Specifically, a 50% increase of confidence to initiate an intervention was observed among managers in the intervention group. CONCLUSIONS: APMaT seems effective to increase managers’ inclination to intervene early against hazardous consumption in the workplace. The effectiveness of APMaT at the employee level should be explored in prospective studies.

Adaptive web-based stress management programs among adults with a cardiovascular disease: A pilot Sequential Multiple Assignment Randomized Trial (SMART)

OBJECTIVE

To assess the feasibility and acceptability of using a Sequential Multiple Assignment Randomized Trial (SMART) to optimize the delivery of a web-based, stress management intervention for patients with a cardiovascular disease (CVD).

METHODS

59 patients with a CVD and moderate stress were randomized to a self-directed web-based stress management program (n = 30) or the same intervention plus lay telephone coaching (n = 29). After 6 weeks, non-responders were re-randomized to continue with their initial intervention or switched to motivational interviewing (MI). Feasibility, acceptability, and clinical significance were assessed.

RESULTS

SMART procedures were feasible. Attrition rates were almost twice as high in the web-only group than the lay coach group. This might be because of the low satisfaction (47%) in the web-only group. On average, 1.7/5 modules were completed. Effect sizes for stress and quality of life generally exceeded 0.2 (clinical benchmark), except for the group that initially received lay coaching and then switched to MI.

CONCLUSIONS

Results suggest that a larger trial would be feasible. Issues pertaining to attrition and satisfaction for non-responders need to be addressed.

PRACTICE IMPLICATIONS

Findings contribute to the evidence on how best to develop and deliver e-Health interventions to maximize their efficacy while remaining cost-effective.

Lessons Learned: Providing Supportive Accountability in an Online Anxiety Intervention

Technology-delivered interventions have the potential to help address the treatment gap in mental health care but are plagued by high attrition. Adding coaching, or minimal contact with a nonspecialist provider, may encourage engagement and decrease dropout, while remaining scalable. Coaching has been studied in interventions for various mental health conditions but has not yet been tested with anxious samples. This study describes the development of and reactions to a low-intensity coaching protocol administered to N = 282 anxious adults identified as high risk to drop out of a web-based cognitive bias modification for interpretation intervention. Undergraduate research assistants were trained as coaches and communicated with participants via phone calls and synchronous text messaging. About half of the sample never responded to coaches' attempts to schedule an initial phone call or did not answer the call, though about 30% completed the full intervention with their coach. Some anxious adults may choose technology-delivered interventions specifically for their lack of human contact and may fear talking to strangers on the phone; future recommendations include taking a more intensive user-centered design approach to creating and implementing a coaching protocol, allowing coaching support to be optional, and providing users with more information about how and why the intervention works.

Effectiveness of eHealth Interventions Targeting Employee Health Behaviors: Systematic Review (Preprint)

BACKGROUND

The number of people with noncommunicable diseases is increasing. Noncommunicable diseases are the major cause of disability and premature mortality worldwide, associated with negative workplace outcomes such as sickness absence and reduced work productivity. There is a need to identify scalable interventions and their active components to relieve disease and treatment burden and facilitate work participation. eHealth interventions have shown potential in clinical and general populations to increase well-being and physical activity and could be well suited for workplace settings.

OBJECTIVE

We aimed to provide an overview of the effectiveness of eHealth interventions at the workplace targeting employee health behaviors and map behavior change techniques (BCTs) used in these interventions.

METHODS

A systematic literature search was performed in PubMed, Embase, PsycINFO, Cochrane CENTRAL, and CINAHL in September 2020 and updated in September 2021. Extracted data included participant characteristics, setting, eHealth intervention type, mode of delivery, reported outcomes, effect sizes, and attrition rates. Quality and risk of bias of the included studies were assessed using the Cochrane Collaboration risk-of-bias 2 tool. BCTs were mapped in accordance with the BCT Taxonomy v1. The review was reported according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) checklist.

RESULTS

In total, 17 randomized controlled trials met the inclusion criteria. The measured outcomes, treatment and follow-up periods, content of eHealth interventions, and workplace contexts had high heterogeneity. Of the 17 studies, 4 (24%) reported unequivocally significant findings for all primary outcomes, with effect sizes ranging from small to large. Furthermore, 53% (9/17) of the studies reported mixed results, and 24% (4/17) reported nonsignificant results. The most frequently targeted behavior was physical activity (15/17, 88% of the studies); the least frequently targeted behavior was smoking (2/17, 12% of the studies). Attrition varied greatly across the studies (0%-37%). Risk of bias was high in 65% (11/17) of the studies, with some concerns in the remaining 35% (6/17). Interventions used various BCTs, and the most frequently used were feedback and monitoring (14/17, 82%), goals and planning (10/17, 59%), antecedents (10/17, 59%), and social support (7/17, 41%).

CONCLUSIONS

This review suggests that, although eHealth interventions may have potential, there are still unanswered questions regarding their effectiveness and what drives the mechanism behind these effects. Low methodological quality, high heterogeneity and complexity, the characteristics of the included samples, and often high attrition rates challenge the investigation of the effectiveness and the making of sound inferences about the effect sizes and significance of the results. To address this, new studies and methods are needed. A megastudy design in which different interventions are evaluated in the same population over the same period on the same outcomes may solve some of the challenges.

Are Organizational EHealth Interventions Becoming More Effective at Addressing Employee Mental Health; A Systematic Review and Meta-Analysis (Preprint)

Background

Mental health conditions are considered the leading cause of disability, sickness absence, and long-term work incapacity. eHealth interventions provide employees with access to psychological assistance. There has been widespread implementation and provision of eHealth interventions in the workplace as an inexpensive and anonymous way of addressing common mental disorders.

Objective

This updated review aimed to synthesize the literature on the efficacy of eHealth interventions for anxiety, depression, and stress outcomes in employee samples in organizational settings and evaluate whether their effectiveness has improved over time.

Methods

Systematic searches of relevant articles published from 2004 to July 2020 of eHealth intervention trials (app- or web-based) focusing on the mental health of employees were conducted. The quality and bias of all studies were assessed. We extracted means and SDs from publications by comparing the differences in effect sizes (Hedge g) in standardized mental health outcomes. We meta-analyzed these data using a random-effects model.

Results

We identified a tripling of the body of evidence, with 75 trials available for meta-analysis from a combined sample of 14,747 articles. eHealth interventions showed small positive effects for anxiety (Hedges g=0.26, 95% CI 0.13-0.39; P<.001), depression (Hedges g=0.26, 95% CI 0.19-0.34; P<.001), and stress (Hedges g=0.25, 95% CI 0.17-0.34; P<.001) in employees’ after intervention, with similar effects seen at the medium-term follow-up. However, there was evidence of no increase in the effectiveness of these interventions over the past decade.

Conclusions

This review and meta-analysis confirmed that eHealth interventions have a small positive impact on reducing mental health symptoms in employees. Disappointingly, we found no evidence that, despite the advances in technology and the enormous resources in time, research, and finance devoted to this area for over a decade, better interventions are being produced. Hopefully, these small effect sizes do not represent optimum outcomes in organizational settings.

Reducing problematic alcohol use in employees: economic evaluation of guided and unguided web-based interventions alongside a three-arm randomized controlled trial

AIMS

To perform an economic evaluation of guided and unguided internet-based interventions to reduce problematic alcohol consumption in employees compared with a waiting-list control condition (WLC) with unrestricted access to treatment-as-usual.

DESIGN

A cost-effectiveness analysis (CEA) and cost-utility analysis (CUA) from a societal and a cost-benefit analysis from the employer's perspective with a 6-month time horizon.

SETTING

Open recruitment in the German working population.

PARTICIPANTS

Employees (178 males, 256 females, mean age 47 years) consuming at least 14 (women) or 21 (men) standard units of alcohol (SUAs) per week and scoring ≥ 8 (men) or 6 (women) on the Alcohol Use Disorders Identification Test.

MEASUREMENTS

On-line questionnaires administered to assess SUAs and assess quality of life (AQoL-8D) and resource use. Outcome measure was responder (≤ 14/≤ 21 SUAs) for the CEA and quality-adjusted life years (QALYs) for the CUA. Net benefit regression was used to estimate cost-effectiveness for each study arm. Bootstrapping and sensitivity analyses were performed to account for uncertainty.

INTERVENTIONS

Five weekly modules including personalized normative feedback, motivational interviewing, goal setting, problem-solving and emotion regulation, provided with adherence-focused guidance [n = 142; responders: n = 73 (51.4%); QALYs = 0.364, standard error (SE) = 0.006] or without guidance [n = 146; n = 66 (45.2%); 0.359, 0.007]. Controls were on a waiting-list [n = 144; n = 38 (26.4%); 0.342, 0.007].

FINDINGS

From a societal perspective, the guided intervention had a probability of 55% (54%) of being the most efficient strategy at a willingness-to-pay (WTP) of €0 per responder (QALY) gained, compared with the unguided intervention and the control condition. At a WTP of €20 000 per QALY gained, the probability was 78%. From an employer's perspective, the guided intervention had a higher probability of a positive return on investment (81%) compared with the unguided intervention (58%).

CONCLUSION

A guided internet-based intervention to reduce problematic alcohol consumption in employees appears to be both cost-beneficial and cost-effective.

App-based maintenance treatment for alcohol use disorder after acute inpatient treatment: Study protocol for a multicentre randomized controlled trial

BACKGROUND

Alcohol use disorder, a prevalent and disabling mental health problem, is often characterized by a chronic disease course. While effective inpatient and aftercare treatment options exist, the transferal of treatment success into everyday life is challenging and many patients remain without further assistance. App-based interventions with human guidance have great potential to support individuals after inpatient treatment, yet evidence on their efficacy remains scarce.

OBJECTIVES

To develop an app-based intervention with human guidance and evaluate its usability, efficacy, and cost-effectiveness.

METHODS

Individuals with alcohol use disorder (DSM-5), aged 18 or higher, without history of schizophrenia, undergoing inpatient alcohol use disorder treatment (N = 356) were recruited in eight medical centres in Bavaria, Germany, between December 2019 and August 2021. Participants were randomized in a 1:1 ratio to either receive access to treatment as usual plus an app-based intervention with human guidance (intervention group) or access to treatment as usual plus app-based intervention after the active study phase (waitlist control/TAU group). Telephone-based assessments are conducted by diagnostic interviewers three and six weeks as well as three and six months after randomization. The primary outcome is the relapse risk during the six months after randomization assessed via the Timeline Follow-Back Interview. Secondary outcomes include intervention usage, uptake of aftercare treatments, AUD-related psychopathology, general psychopathology, and quality of life.

DISCUSSION

This study will provide further insights into the use of app-based interventions with human guidance as maintenance treatment in individuals with AUD. If shown to be efficacious, the intervention may improve AUD treatment by assisting individuals in maintaining inpatient treatment success after returning into their home setting. Due to the ubiquitous use of smartphones, the intervention has the potential to become part of routine AUD care in Germany and countries with similar healthcare systems.

Feasibility, Acceptability, and Clinical Significance of a Dyadic, Web-Based, Psychosocial and Physical Activity Self-Management Program (TEMPO) Tailored to the Needs of Men with Prostate Cancer and Their Caregivers: A Multi-Center Randomized Pilot Trial

Background: Prostate cancer is the most common cancer diagnosis among men. Family caregivers (often female spouses) play a key role in ensuring patients’ needs are met, frequently assuming their role with no formal training, which can contribute to a high burden. The purpose of this study was to pilot TEMPO—the first dyadic, Tailored, wEb-based, psychosocial and physical activity self-Management PrOgram for men with prostate cancer and their caregivers. Methods: 49 men with prostate cancer and their caregivers were randomized to TEMPO or usual care. Baseline and follow-up questionnaires were completed to assess feasibility, acceptability, and clinical significance. A priori benchmarks for these outcomes were set. Thirteen exit interviews were conducted to further explore acceptability. Results: Feasibility benchmarks were met with the exception for recruitment with on average 6.1 dyads recruited/month (benchmark: 8 dyads/month). Benchmarks of acceptability focused on attrition (<25%) and system usability, which were met. Using the strict criteria for adherence of 100% of the module viewed and participants spending at least 15 min on the module, 45% of participants were adherent. The clinical significance on anxiety and quality of life was supported for caregivers, and mostly supported for the men with prostate cancer. Conclusion: This pilot trial was successful, with minor modifications needed prior to a large trial.

A randomized controlled trial of the web-based drinking diary program for problem drinking in multi workplace settings

Objectives

To assess the effectiveness of a web‐based brief intervention (BI) program to record daily drinking among people with problem drinking in workplace settings.

Methods

A two‐armed, parallel‐group, randomized controlled trial were conducted at six workplaces in Japan. After obtaining written consent to participate in the study, workers with an Alcohol Use Disorders Identification Test (AUDIT) score of 8 or higher were randomly assigned into two groups. The participants allocated to the intervention group recorded their daily alcohol consumption for 4 weeks using the program, while those allocated to the control group received no intervention. Outcome measures included the amount of alcohol consumption in past 7 days using the Timeline Follow‐Back method in the program at baseline, 8th week, and 12th week and written AUDIT score at baseline and 12th week.

Results

Hundred participants were assigned to either the intervention group (n = 50) or control group (n = 50). The results of two‐way repeated measures ANOVA showed a statistically significant interaction between the group and the week factors in the two primary outcomes (number of alcohol‐free days, total drinks) and secondary outcomes (AUDIT score) (p = .04, .02, and .03, respectively). The between‐group effect sizes (Hedges' g; 95% CI) of the outcomes at 12th week were 0.53; 0.13–0.93 (total drinks), 0.44; 0.04–0.84 (AUDIT score), 0.43; 0.03–0.83 (number of alcohol‐free days).

Conclusions

The web‐based BI program for problem drinking was considered to be effective in reducing alcohol consumption and the AUDIT score in workplace settings.

Technological Interventions for the Treatment of Substance Use Disorders

Substance use disorders (SUDs) pose a major public health concern. In recent years, technological (i.e., e-health) interventions have emerged and are increasingly offered in a variety of settings, including substance use treatment. E-health interventions encompass a wide variety of advantages depending on the chosen delivery format. This chapter discusses existing interventions and the effectiveness of delivering them as an e-health intervention, with a focus on randomized controlled trials, for the treatment of alcohol, cannabis, opioid, psychostimulant, or poly-substance use, as well as in transdiagnostic interventions. Based on the literature, suggestions for future research and clinical implications are discussed.

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.

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

Background

Alcohol use is a major contributor to health loss. Many persons with harmful use or alcohol dependence do not obtain treatment because of limited availability or stigma. They may use internet-based interventions as an alternative way of obtaining support. Internet-based interventions have previously been shown to be effective in reducing alcohol consumption in studies that included hazardous use; however, few studies have been conducted with a specific focus on harmful use or alcohol dependence. The importance of therapist guidance in internet-based cognitive behavioral therapy (ICBT) programs is still unclear.

Objective

This trial aims to investigate the effects of a web-based alcohol program with or without therapist guidance among anonymous adult help-seekers.

Methods

A three-armed randomized controlled trial was conducted to compare therapist-guided ICBT and self-help ICBT with an information-only control condition. Swedish-speaking adult internet users with alcohol dependence (3 or more International Classification of Diseases, Tenth Revision criteria) or harmful alcohol use (alcohol use disorder identification test>15) were included in the study. Participants in the therapist-guided ICBT and self-help ICBT groups had 12-week access to a program consisting of 5 main modules, as well as a drinking calendar with automatic feedback. Guidance was given by experienced therapists trained in motivational interviewing. The primary outcome measure was weekly alcohol consumption in standard drinks (12 g of ethanol). Secondary outcomes were alcohol-related problems measured using the total alcohol use disorder identification test-score, diagnostic criteria for alcohol dependence and alcohol use disorder, depression, anxiety, health, readiness to change, and access to other treatments or support. Follow-up was conducted 3 (posttreatment) and 6 months after recruitment.

Results

During the recruitment period, from March 2015 to March 2017, 1169 participants were included. Participants had a mean age of 45 (SD 13) years, and 56.72% (663/1169) were women. At the 3-month follow-up, the therapist-guided ICBT and control groups differed significantly in weekly alcohol consumption (−3.84, 95% Cl −6.53 to −1.16; t₄₁₇=2.81; P=.005; Cohen d=0.27). No significant differences were found in weekly alcohol consumption between the self-help ICBT group and the therapist-guided ICBT at 3 months, between the self-help ICBT and the control group at 3 months, or between any of the groups at the 6-month follow-up. A limitation of the study was the large number of participants who were completely lost to follow-up (477/1169, 40.8%).

Conclusions

In this study, a therapist-guided ICBT program was not found to be more effective than the same program in a self-help ICBT version for reducing alcohol consumption or other alcohol-related outcomes. In the short run, therapist-guided ICBT was more effective than information. Only some internet help-seekers may need a multisession program and therapist guidance to change their drinking when they use internet-based interventions.

Are guided internet-based interventions for the indicated prevention of depression in green professions effective in the long run? Longitudinal analysis of the 6- and 12-month follow-up of a pragmatic randomized controlled trial (PROD-A)

OBJECTIVE

Evidence of long-term stability for positive mental health effects of internet-based interventions (IBIs) for depression prevention is still scarce. We evaluate long-term effectiveness of a depression prevention program in green professions (i.e. agriculture, horticulture, forestry).

METHODS

This pragmatic RCT (n = 360) compares a tailored IBI program to enhanced treatment as usual (TAU+) in green professions with at least subthreshold depression (PHQ ≥ 5). Intervention group (IG) received one of six IBIs shown previously to efficaciously reduce depressive symptoms. We report 6- and 12-month follow-up measures for depression, mental health and intervention-related outcomes. Intention-to-treat and per-protocol regression analyses were conducted for each measurement point and complemented by latent growth modeling.

RESULTS

After 6 months, depression severity (β = -0.30, 95%-CI: -0.52; -0.07), insomnia (β = -0.22, 95%-CI: -0.41; -0.02), pain-associated disability (β = -0.26, 95%-CI: -0.48; -0.04) and quality of life (β = 0.29, 95%-CI: 0.13; 0.45) in IG were superior to TAU+. Onset of possible depression was not reduced. After 12 months, no intervention effects were found. Longitudinal modeling confirmed group effects attenuating over 12 months for most outcomes. After 12 months, 55.56% of IG had completed at least 80% of their IBI.

CONCLUSIONS

Stability of intervention effects along with intervention adherence was restricted. Measures enhancing long-term effectiveness of IBIs for depression health promotion are indicated in green professions.

A three-armed randomised controlled trial investigating the comparative impact of guidance on the efficacy of a web-based stress management intervention and health impairing and promoting mechanisms of prevention

Background

Web-based stress management interventions (SMI) fit increasingly digital lifestyles, reduce barriers of uptake and are easily scalable. SMIs might lower levels of stress in employees and thereby contribute to the prevention of depressive symptomatology. Different guidance formats can impact the efficacy of SMIs, with higher intensity assumed to result in larger effects. However, head-to-head comparisons of guidance formats are rare. This is the first trial to examine the impact of adherence-focused guidance compared to self-help on the efficacy of an occupational SMI compared to a wait list control condition. Additionally, it will be investigated if the SMI enfolds its impact on preventing depressive symptomatology by different pathways through reducing health impairing and increasing promoting factors.

Methods

A three-armed randomised controlled trial (RCT) on an occupational SMI was conducted. 404 employees with elevated levels of perceived stress (PSS-10 ≥ 22) were randomly assigned to: adherence-focused guidance (AFG), self-help (SH) or a wait list control group (WLC). The primary outcome was perceived stress (PSS-10). Secondary outcomes included health- and work-related measures. A parallel mediation analysis with stress and resilience as mediators for the effect on depression (CES-D) was carried out. Data collection took place at baseline (T1), after 7 weeks (T2) and 6 months (T3).

Results

The SMI was effective for all groups on the primary and secondary outcomes. For stress, analyses of covariance (ANCOVA) revealed significant group effects at T2 (F_2,400 = 36.08, P < .001) and T3 (F_2,400 = 37.04, P < .001) with large effect sizes for AFG (T2: d = 0.83; T3: d = 0.85) and SH (T2: d = 0.88; T3: d = 0.91) compared to WLC. No significant group differences were found for the efficacy between AFG and SH on the outcomes. Adherence in terms of completed modules was significantly higher for AFG compared to SH. The SMI’s impact on depression was mediated by perceived stress: a₁b₁ = − 0.77, 95% CI [− 1.26, − 0.34] and resilience: a₂b₂ = − 0.62, 95% CI [− 1.05, − 0.26].

Conclusions

The SMI was effective for reducing stress and improving other health- and work-related outcomes, irrespective of the guidance format. Results did not demonstrate superiority of adherence-focused guidance for the efficacy but for adherence in terms of completed modules. Among other reasons, better communication strategies about offered guidance and awareness-raising measures are discussed. Results from mediation analysis suggest that preventive SMIs should be designed to reach two goals: reducing the risk factor of stress and simultaneously increasing health promoting factors such as resilience.

Digital mHealth Interventions for Employees: Systematic Review and Meta-Analysis of Their Effects on Workplace Outcomes

OBJECTIVES

To justify the capital investment, employers require proof of benefit of digital mHealth beyond symptomatic improvement.

METHODS

A systematic review and meta-analysis were conducted to identify studies investigating digital mHealth interventions for employees and their effects on workplace outcomes.

RESULTS

We identified 28 eligible studies, (8023 employees) comparing digital mHealth interventions to controls. Small significant effects at postintervention in engagement (g = 0.19), and productivity (g = 0.16) were found. Sustained effects were observed, engagement (g = 0.24) and productivity (g = 0.20). There was a wide range of study heterogeneity (I2 = 16% to 94%).

CONCLUSION

In RCTs digital mHealth interventions demonstrate small, potentially sustained efficacy on employee's engagement and productivity. Similar small yet non-significant effect sizes were seen for absenteeism and presenteeism. This supports the need to find ways of enabling employers to deliver these low-cost digital mHealth interventions that can help improve employee's mental health.

Alcohol intoxication incidence differences at companies in Lithuania

INTRODUCTION

Employee alcohol consumption is a major challenge to both the health of the employee and productivity of the company. Our study investigates the overall alcohol intoxication rates of employees at companies in Lithuania, alcohol intoxication incidence rates during the work week and associations between company variables and employee alcohol intoxication at work.

METHODS

Data for our study were collected at 153 different companies in Lithuania during the year 2018. Overall 2 455 997 alcohol breath tests were analysed. Data were analysed using descriptive statistics and Poisson regression analysis.

RESULTS

Descriptive statistics showed that the alcohol intoxication (blood alcohol concentration ≥ 0.01%) incidence rate was 0.31% (n = 7535). Average alcohol intoxication was 0.04%. Furthermore, higher alcohol intoxication incidence rates were found on Mondays and in the morning than at any other day or time. The results of Poisson regression analysis showed that the alcohol intoxication incidence rate ratios were highest among small companies, companies from the farming sector and companies from rural areas.

DISCUSSION AND CONCLUSIONS

We found a relationship between company variables, testing time and incidence rates of alcohol intoxication. The increased alcohol intoxication at work throughout the weekend and on Monday is consistent with the alcohol consumption patterns in the Lithuanian population. Relatively low alcohol intoxication rate for the majority of the positively tested cases may indicate consumption of small amounts of alcohol just before starting work or excessive alcohol consumption the day before. Our findings could be an indicator of an underlying problem and have implications for alcohol prevention strategies.

Associations between occupation and heavy alcohol consumption in UK adults aged 40-69 years: a cross-sectional study using the UK Biobank

BACKGROUND

Understanding the relationship between occupation and alcohol use offers opportunities to provide health promotion programmes based on evidence of need. We aimed to determine associations between occupation and heavy alcohol consumption in working individuals aged 40-69 years.

METHODS

A cross-sectional study was conducted using 100,817 people from the UK Biobank: 17,907 participants categorised as heavy drinkers, defined as > 35 units/week for women and > 50 units/week for men, and 82,910 drinking controls. Prevalence ratios (PRs) and 95% CIs were calculated for gender-specific heavy drinking in 353 occupations using Standard Occupational Classification, V.2000.

RESULTS

Seventy-seven occupations were associated with level of alcohol consumption in drinkers. The largest ratios for heavy drinkers were observed for publicans and managers of licenced premises (PR = 2.81, 95%CI 2.52-3.14); industrial cleaning process occupations (PR = 2.09, 1.33-3.28); and plasterers (PR = 2.07, 1.66-2.59). Clergy (PR = 0.20, 0.13-0.32); physicists, geologists and meteorologists (PR = 0.40, 0.25-0.65); and medical practitioners (PR = 0.40, 0.32-0.50) were least likely to be heavy drinkers. There was evidence of gender-specific outcomes with the proportion of jobs associated with heavy drinking accounted for by skilled trade occupations being 0.44 for males and 0.05 for females, and 0.10 for males and 0.40 for females when considering managers and senior officials.

CONCLUSIONS

In the largest study of its kind, we found evidence for associations between a wider variety of occupations and the risk of heavy alcohol consumption than identified previously, particularly in females, although causality cannot be assumed. These results help determine which jobs and broader employment sectors may benefit most from prevention programmes.

Effectiveness of guided internet-based interventions in the indicated prevention of depression in green professions (PROD-A): Results of a pragmatic randomized controlled trial

BACKGROUND

Major Depressive Disorder (MDD) has a major impact on public health. Reduction of depression burden in general population is of greatest importance and might be achieved by implementation of depression prevention measures into routine care. We evaluate an online prevention measure as part of a national project aiming to reduce depression in the occupational group of green professions.

METHODS

This two-armed pragmatic RCT (n = 360) evaluates the effectiveness of a tailored internet-based intervention (IMI) program compared to enhanced treatment as usual. The IMI program entailed access to one of six guided IMIs each focusing on different symptom areas (depressive mood with optional comorbid diabetes, perceived stress, insomnia, panic and agoraphobia and harmful alcohol consumption). Eligible were entrepreneurs, spouses, family members and pensioners in green professions with adequate insurance status and at least subthreshold depression (PHQ≥5). Primary outcome was depressive symptom severity (QIDS-SR16) at 9-weeks post-treatment (T1). Various secondary outcomes were assessed at T1.

RESULTS

A small effect of depression reduction (d=-0.28, 95%-CI: -0.50 to -0.07) was found at T1 favouring the IMI program (β=-0.22, 95%-CI: -0.41 to -0.02, p=.033). Categorical analysis indicated a reduced risk of potential MDD with NNTB=28.11. Adherence to the IMI program at T1 was exceptionally low.

LIMITATIONS

Results are limited to green professions and representativeness might be restricted by self-selection of participants.

CONCLUSION

Depression burden in green professions can be reduced by this online prevention measure. Yet, short-term effectiveness is restricted by low adherence rates.

Reading, Conducting, and Developing Systematic Review and Individual Patient Data Meta-Analyses in Psychiatry for Treatment Issues

Introduction: Individual participant data meta-analyses (IPD-MAs) include the raw data from relevant randomised clinical trials (RCTs) and involve secondary analyses of the data. Performed since the late 1990s, ~50 such meta-analyses have been carried out in psychiatry, mostly in the field of treatment. IPD-MAs are particularly relevant for three objectives: (1) evaluation of the average effect of an intervention by combining effects from all included trials, (2) evaluation of the heterogeneity of an intervention effect and sub-group analyses to approach personalised psychiatry, (3) mediation analysis or surrogacy evaluation to replace a clinical (final) endpoint for the evaluation of new treatments with intermediate or surrogate endpoints. The objective is to describe the interest and the steps of an IPD-MA method applied to the field of psychiatric therapeutic research. Method: The method is described in three steps. First, the identification of the relevant trials with an explicit description of the inclusion/exclusion criteria for the RCT to be incorporated in the IPD-MA and a definition of the intervention, the population, the context and the relevant points (outcomes or moderators). Second, the data management with the standardisation of collected variables and the evaluation and the assessment of the risk-of-bias for each included trial and of the global risk. Third, the statistical analyses and their interpretations, depending on the objective of the meta-analysis. All steps are illustrated with examples in psychiatry for treatment issues, excluding study protocols. Conclusion: The meta-analysis of individual patient data is challenging. Only strong collaborations between all stakeholders can make such a process efficient. An "ecosystem" that includes all stakeholders (questions of interest prioritised by the community, funders, trialists, journal editors, institutions, …) is required. International medical societies can play a central role in favouring the emergence of such communities.

How to achieve greater comparability-suggested ways to improve the determination of treatment gap and treatment lag

Purpose

The aim of this paper is to reveal these problems and to derive recommendations for improvement. In the field of alcohol use disorders (AUDs), two common complaints are the large treatment gap that exists because only a small percentage of people with an AUD are in treatment; and the prolonged lag that typically exists between the emergence of problematic symptoms and actual on set of treatment. However, there also are no clear definitions for these terms – “treatment gap” and “treatment lag” – and, therefore, no consensus regarding how to quantify them. For this reason, it is difficult to compare the results of studies assessing either of these measures.

Design/methodology/approach

A non-systematic literature search and logical-analytical investigation was performed of immanent problems related to definitions and measurements aiming to enhance understanding in this area and derive suggestions for improvement.

Findings

The following four fundamental questions were identified: How does one operationalise the need to change substance use behaviours? Which interventions can justifiably be called treatment? Is treatment always necessary? and How regularly do patients need to be in contact with a treatment system to be considered “in treatment”? Potential approaches to answering these questions are discussed and recommendations made for future studies to determine how the treatment gap and treatment lag should be derived.

Originality/value

The derived recommendations should make the calculation of treatment gap and treatment lag more transparent and comparable between studies. They also may serve as checklists for future studies on the treatment gap and lag in the AUD field.

Feasibility of a Brief Online Psychoeducational Intervention for Women With Sexual Interest/Arousal Disorder

Background

Low sexual desire and arousal are the most common sexual concerns in women, but most women lack access to effective treatment such as cognitive behavioral therapy. Web-based psychological interventions, which are economical, private, easily accessible, and potentially effective, may increase the reach of evidence-based treatment.

Aim

To determine the feasibility of translating cognitive behavioral therapy for the most common female sexual dysfunction, Female Sexual Interest/Arousal Disorder, into an online format. The present study examined the feasibility of an introductory psychoeducational module of eSense, an online program currently being developed that is based on existing empirically supported in-person treatments, which delivers content to the user in a visually appealing and interactive manner.

Methods

Sixteen cisgender women (M age = 31.9) with female sexual arousal/interest disorder worked through a pilot module of eSense inperson at a sexual health laboratory.

Outcomes

Qualitative semistructured interviews and online questionnaires were used to assess participants’ experiences of usability of the platform, clarity/relevance of the content, satisfaction with the experience, and any changes in clinical outcomes of sexual function and distress.

Results

Participants reported a high level of satisfaction with the website’s functionality and presentation. They reported greater knowledge, felt validated and more hopeful, and were eager to continue the remaining modules. Participants also reported notable prepost improvements in sexual desire, arousal, and satisfaction.

Clinical Implications

Initial user-experience assessment may represent a method of simultaneously improving online interventions and providing therapeutic education to participants.

Strengths & Limitations

This is one of the first studies, to our knowledge, to test a graphics-rich, interactive online intervention for sexual difficulties that does not require direct contact with expert providers or support groups. Limitations include the high level of education, motivation, and technical fluency of the sample and the potentially confounding effect of the researcher’s presence during interviews. Because this was a feasibility study, the sample size was small, and no control group was included, limiting conclusions about efficacy and generalizability.

Conclusion

The format of eSense appears to be feasible and usable, lending support to the growing evidence that it is possible to take in-person therapeutic interventions online.

Implementing internet- and tele-based interventions to prevent mental health disorders in farmers, foresters and gardeners (ImplementIT): study protocol for the multi-level evaluation of a nationwide project

BACKGROUND

Farmers are a vulnerable population for developing depression or other mental health disorders due to a variety of risk factors in their work context. Beyond face-to-face resources, preventive internet- and tele-based interventions could extend available treatment options to overcome barriers to care. The German Social Insurance Company for Agriculture, Forestry and Horticulture (SVLFG) implements several guided internet- and mobile-based interventions and personalised tele-based coaching for this specific target group provided by external companies within a nation-wide prevention project for their insured members. The current study aims to evaluate the implementation process and to identify determinants of successful implementation on various individual and organisational levels.

METHODS

The current study includes two groups of participants: 1) insured persons with an observable need for prevention services, and 2) staff-participants who are involved in the implementation process. The Reach, Effectiveness, Adoption, Implementation and Maintenance (RE-AIM) framework and the Consolidated Framework for Implementation Research (CFIR) will be used to track and evaluate the implementation process. A mixed-method approach will provide insights on individual and organizational level (e.g. degree of normalization, readiness for change) and helps to identify determinants of successful implementation. In-depth insights on experiences of the participants (e.g. acceptance, satisfaction, barriers and facilitating factors of intervention use) will be yielded through qualitative interviews. Focus groups with field workers provide insights into barriers and facilitators perceived during their consultations. Furthermore, intervention as well as implementation costs will be evaluated. According to the stepwise, national rollout, data collection will occur at baseline and continuously across 24 months.

DISCUSSION

The results will show to what extent the implementation of the internet- and tele-based services as a preventive offer will be accepted by the participants and involved employees and which critical implementation aspects will occur within the process. If the implementation of the internet- and tele-based services succeeds, these services may be feasible in the long-term.

Effectiveness of Combining Organizational Alcohol Policy and Skills Training for Managers to Reduce Hazardous Alcohol Consumption in Swedish Workplaces: Study Protocol for a Cluster Randomized Study

Background

High alcohol consumption poses risks to individual health and society. Previous alcohol interventions have mainly focused on high-risk consumers or young adults in school-based settings. Since the majority of the adult population is in the workforce, the workplace can be considered a favorable arena for implementing interventions.

Objective

This protocol describes a project aimed at increasing knowledge of the effectiveness of combining the implementation of an organizational alcohol policy with skills training for managers as a workplace alcohol prevention program, by evaluating the intervention and exploring managers’ perceptions of the intervention.

Methods

Organizations with at least 100 employees were invited to take part in the project. A total of 11 organizations (744 managers and 11,761 employees) were included in the project. Data are collected through self-administered online surveys at baseline, 12 months, and 24 months. The primary outcome is managers’ inclination to initiate an early alcohol intervention (eg, by initiating a dialogue) when concern regarding employees’ hazardous alcohol consumption arises. The secondary outcomes of interest are managers’ and employees’ organizational alcohol policy knowledge and changes in alcohol consumption, as measured using the Alcohol Use Disorder Identification Test (AUDIT) score. A linear mixed-model framework will be used to model variability on different levels. Primary analysis will follow an intention-to-treat approach. Additionally, managers’ responses from semistructured interviews will be analyzed using thematic analysis to explore managers’ experiences regarding the prevention program.

Results

This study is ongoing. The overall study start was on January 2018, and the study is planned to end in December 2020. Baseline and 12-month follow-up measurements have been collected.

Conclusions

This project is designed to evaluate the effectiveness of an alcohol prevention program regarding higher inclination to initiate early alcohol interventions after policy implementation and skills training among managers, compared to the usual practices in the workplace. The results from this study can contribute to increased knowledge about alcohol interventions and future prevention programs in the workplace.

Ethische Aspekte internet- und mobilgestützter Interventionen (IMIs) bei Suchtstörungen

Ziel der Studie Internet- und mobilgestützte Interventionen (IMIs) werden häufig bei Suchtstörungen eingesetzt. Für die Wirksamkeit von IMIs liegt eine umfangreiche Evidenz vor. Hinsichtlich der spezifischen ethischen Aspekte, die sich aus dem Einsatz von IMIs bei Suchtstörungen ergeben, fehlt es bislang an Forschung. Mit unserem Beitrag leisten wir die erste eingehende ethische Analyse von IMIs in der Suchttherapie. Dabei orientieren wir uns an normativen Aspekten, die spezifisch für die Behandlung von Suchtstörungen sind. Dazu gehören die besondere Stigmatisierung von Suchtkranken, die Zuschreibung von Schuld und Eigenverantwortung, die mangelnde Akzeptanz des Krankheitskonzepts Sucht sowie die daraus resultierende Ablehnung und Abwertung von Betroffenen.

Methode Als methodisches Instrument verwenden wir den 3 ACES-Ansatz von Thornicroft und Tansella. Dieses Instrument erlaubt eine umfassende ethische Analyse des Einsatzes von IMIs im konkreten Einzelfall sowie der Implementierung von IMIs im Versorgungssystem.

Ergebnisse Unsere Analyse zeigt, dass IMIs in der Suchttherapie das Potential haben, ein Empowerment von PatientInnen zu leisten, die Stigmatisierung zu umgehen und einen niedrigschwelligen Zugang zu Versorgungsleistungen zu ermöglichen. Kritisch zu sehen sind Aspekte der Passung von Anwendungen auf die Bedürfnisse einzelner Patientengruppen und individueller PatientInnen, der therapeutischen Verantwortung, des Datenschutzes, der Datensicherheit und Privatheit sowie der Vernetzung unterschiedlicher Anbieter von Versorgungsleistungen.

Schlussfolgerung Eine weitere Implementierung von IMIs in der Suchttherapie ist nur dann wünschenswert, wenn verbindliche Qualitätsstandards geschaffen und die patientenzentrierte Anwendung unter Berücksichtigung individueller Patientencharakteristika sichergestellt wird.

Workplace alcohol prevention: are managers' individual characteristics associated with organisational alcohol policy knowledge and inclination to initiate early alcohol interventions?

Purpose

Individual factors associated with managers' organisational alcohol policy knowledge and inclination to initiate early alcohol interventions have been understudied. This study aims to examine differences in managers' policy knowledge and inclination across a range of socio-demographic, work-related and health characteristics, and it aims to examine the association between policy knowledge and inclination to intervene, net of these characteristics.

Design/methodology/approach

Questionnaire data were collected from 430 managers. Organisational alcohol policy knowledge and inclination to intervene were measured using a 5-point Likert scale ranging from 1 (very low) to 5 (very high). Socio-demographic, work-related and health characteristics included gender, age, education, managerial responsibility, years in current position, self-rated health and alcohol consumption. Associations were examined using multilevel ordinal regression analysis.

Findings

Managers with a greater number of employees demonstrated the highest level of organisational alcohol policy knowledge and were more inclined to initiate early alcohol interventions. Alcohol policy knowledge was associated with inclination to intervene, net of individual characteristics.

Practical implications

Considering how managers' characteristics might influence efforts to decrease hazardous alcohol consumption is potentially important when designing future workplace alcohol prevention programmes.

Originality/value

Several individual factors related to managers' organisational alcohol policy knowledge and inclination to initiate early alcohol interventions were identified, particularly managerial responsibility. However, the association between policy knowledge and inclination to intervene remained strong after accounting for these individual factors. Future studies should explore alternative explanations at the individual and organisational levels.

Internet-Delivered Cognitive Behavioral Therapy for Problematic Alcohol Use in a Workplace Setting: Protocol for Quantitative and Qualitative Evaluation of Feasibility and Outcomes

BACKGROUND

Internet-based cognitive behavioral therapy (ICBT) for mental health issues has been successfully implemented in routine health care settings, and research indicates that ICBT can also be applied to decrease problematic alcohol use in workplace settings. However, studies investigating the feasibility of implementing ICBT in a workplace setting have been lacking.

OBJECTIVE

The current study aims to investigate the feasibility of delivering ICBT for problematic alcohol use within an employee assistance program (EAP).

METHODS

The study has a quantitative naturalistic design, quantitively comparing ICBT and face-to-face treatment, and allowing for qualitative interviews with employees and employers. Recruitment of participants follows a five-session in-person psychological assessment at an EAP regarding an employee's presumed problematic alcohol consumption. All assessed employees referred to ICBT or face-to-face treatment will be offered participation in the study. Interviews will be held with employees and their employer representatives following ICBT to elucidate both stakeholders' experience and perception of ICBT and its context. Outcome comparisons between ICBT and face-to-face treatment will be assessed quantitatively using a Reliable Change Index and analysis of variance. Thematic analysis and Grounded Theory will be used to analyze the interview material.

RESULTS

The study is set to begin in April 2020 and to end in September 2021. The aim is to recruit up to 150 participants to the quantitative part of the study and 45 participants (15 employees and 30 employer representatives) to the qualitative part of the study.

CONCLUSIONS

The current study will provide knowledge that is lacking and urgently needed on how to implement ICBT for problematic alcohol use in a workplace setting.

Measures of Effectiveness, Efficiency, and Quality of Telemedicine in the Management of Alcohol Abuse, Addiction, and Rehabilitation: Systematic Review

Background

More than 18 million Americans are currently suffering from alcohol use disorder (AUD): a compulsive behavior of alcohol use as a result of a chronic, relapsing brain disease. With alcohol-related injuries being one of the leading causes of preventable deaths, there is a dire need to find ways to assist those suffering from alcohol dependence. There still exists a gap in knowledge as to the potential of telemedicine in improving health outcomes for those patients suffering from AUD.

Objective

The purpose of this systematic review was to evaluate the measures of effectiveness, efficiency, and quality that result from the utilization of telemedicine in the management of alcohol abuse, addiction, and rehabilitation.

Methods

This review was conducted utilizing the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The articles used in this analysis were gathered using keywords inclusive of both telemedicine and alcohol abuse, which were then searched in the Cumulative Index to Nursing and Allied Health Literature, Cochrane, and MEDLINE (PubMed) databases. A total of 22 articles were chosen for analysis.

Results

The results indicated that telemedicine reduced alcohol consumption. Other common outcomes included reduced depression (4/35, 11%), increased patient satisfaction (3/35, 9%), increase in accessibility (3/35, 9%), increased quality of life (2/35, 6%), and decreased cost (1/35, 3%). Interventions included mobile health (11/22, 50%), electronic health (6/22, 27%), telephone (3/33, 14%), and 2-way video (2/22, 9%). Studies were conducted in 3 regions: the United States (13/22, 59%), the European Union (8/22, 36%), and Australia (1/22, 5%).

Conclusions

Telemedicine was found to be an effective tool in reducing alcohol consumption and increasing patients’ accessibility to health care services or health providers. The group of articles for analysis suggested that telemedicine may be effective in reducing health care costs and improving the patient’s quality of life. Although telemedicine shows promise as an effective way to manage alcohol-related disorders, it should be further investigated before implementation.

Can Brief Email Guidance Enhance the Effects of an Internet Intervention for People with Problematic Alcohol Use? A Randomized Controlled Trial

Some research suggests that internet interventions aimed at people with problematic alcohol use are more effective when provided with guidance from a therapist or coach. Purpose/Objectives: This trial intended to compare the effects of a previously evaluated internet intervention for people with problematic alcohol use when delivered with or without brief email guidance. Methods: Using online advertising, 238 participants, 18 years or older, were recruited and randomized to receive access to the Internet intervention Alcohol Help Center with or without brief email guidance from a health educator. The guidance consisted of at least four structured, slightly individualized emails delivered during the first two weeks after randomization. Participants were followed up at 3 and 6 months. Results: Number of log-ins did not differ significantly between groups throughout the follow-up period. The follow-up rate at 6 months was 47.0%. Generalized estimating equations run on the primary (standard drinks in preceding week/heavy drinking days in preceding week) and secondary outcome variables (AUDIT, AUDIT-C, quality of life) revealed no significant differences between the interventions on any of the outcomes. Conclusions/Importance: The study does not provide support for any added benefits of providing brief guidance via email in an internet intervention for problem drinkers.

Clinical and Cost-Effectiveness of Personalized Tele-Based Coaching for Farmers, Foresters and Gardeners to Prevent Depression: Study Protocol of an 18-Month Follow-Up Pragmatic Randomized Controlled Trial (TEC-A)

Background: Farmers show high levels of depressive symptoms and mental health problems in various studies. This study is part of a nationwide prevention project carried out by a German social insurance company for farmers, foresters, and gardeners (SVLFG) to implement internet- and tele-based services among others to improve mental health in this population. The aim of the present study is to evaluate the (cost-)effectiveness of personalized tele-based coaching for reducing depressive symptom severity and preventing the onset of clinical depression, compared to enhanced treatment as usual. Methods: In a two-armed, pragmatic randomized controlled trial (N = 312) with follow-ups at post-treatment (6 months), 12 and 18 months, insured farmers, foresters, and gardeners, collaborating family members and pensioners with elevated depressive symptoms (PHQ-9 ≥ 5) will be randomly allocated to personalized tele-based coaching or enhanced treatment as usual. The coaching is provided by psychologists and consists of up to 34 tele-based sessions for 25-50 min delivered over 6 months. Primary outcome is depressive symptom severity at post-treatment. Secondary outcomes include depression onset, anxiety, stress, and quality of life. A health-economic evaluation will be conducted from a societal perspective. Discussion: This study is the first pragmatic randomized controlled trial evaluating the (cost-)effectiveness of a nationwide tele-based preventive service for farmers. If proven effective, the implementation of personalized tele-based coaching has the potential to reduce disease burden and health care costs both at an individual and societal level.

A meta-analysis of the effect of substance use interventions on emotion outcomes

OBJECTIVE

Emotional distress has been posited as a key underlying mechanism in the development and maintenance of substance use disorder (SUD), and patients seeking SUD treatment are often experiencing high levels of negative emotion and/or low levels of positive emotion. But the extent to which SUD interventions impact emotional outcomes among general SUD populations is yet unquantified. The current meta-analysis aims to fill this gap.

METHOD

A total of 11,754 records were screened for randomized, controlled trials examining the effect of behavioral SUD interventions on emotion outcomes. Our search yielded a total of 138 effect sizes calculated based on data from 5,146 individuals enrolled in 30 independent clinical trials. Random-effects meta-analysis was used to calculate pooled effect sizes, and metaregression analyses examined study-level moderators (e.g., intervention type).

RESULTS

Findings indicated a small but significant effect of SUD interventions on emotion outcomes, d = 0.157, 95% CI [0.052, 0.262] (k = 30). The effect size for negative emotion was nominally bigger, d = 0.162, 95% CI [0.056, 0.269] (k = 30), whereas the effect for positive emotion did not reach statistical significance, d = 0.062, 95% CI [-0.089, 0.213] (k = 7). Studies featuring SUD interventions designed to specifically target emotions (i.e., affect-regulation, mindfulness-based treatments) produced larger reductions in negative emotion compared with studies featuring interventions that did not contain specific emotion modules (e.g., contingency management).

CONCLUSIONS

Findings suggest that SUD interventions-especially mindfulness-based and affect-regulation treatments-indeed significantly reduce negative emotion, although relatively small effect sizes indicate potential room for improvement. Conclusions regarding positive emotion should be considered preliminary because of the limited numbers of samples assessing these outcomes.

Digital Mental Health for Alcohol and Substance Use Disorders

Purpose

Only about 20% of people suffering from substance use disorders access available treatments due to various obstacles; digital interventions could potentially overcome some of these. Meta-analyses suggest the strongest evidence for interventions targeting alcohol use reduction, followed by cannabis and illicit substances. However, most randomized controlled trials (RCTs) used unguided standalone interventions compared to non-active controls, with limited follow-up periods and disregarded comorbidity. This review examines the literature published over the last three years (2016–2019), with a focus on recent RCTs and whether they addressed some of these gaps.

Recent findings

Except for digital interventions targeting alcohol use, the number of RCTs in the last three years is limited. Although there is considerable heterogeneity between the studies, most of them applied unguided add-on interventions compared to active control groups, and a limited number investigated guided interventions. In addition, there is a need for longer follow-up periods, active rather than non-active control groups, outcome standardization, and increased focus on comorbidity.

Summary

Although the number of studies using guided add-on or blended interventions compared to active controls has increased, future studies should consider our identified gaps and suggestions to further strengthen the evidence of digital interventions for reducing the use of alcohol and other substances.

Are Computer-Based Treatment Programs Effective at Reducing Symptoms of Substance Misuse and Mental Health Difficulties Within Adults? A Systematic Review

Objective: Comorbid substance misuse and mental health difficulties are recognized as a leading contributor to disease burden worldwide. Amid cuts to health care services, computer-based interventions may provide support for patients experiencing these difficulties. The aims of this systematic review were to identify and investigate the efficacy of these computer-based interventions at improving substance misuse and mental health outcomes.Methods: A systematic search was conducted of CINAHL Plus, PsycARTICLES, PsycINFO, Medline, Web of Science, and the Cochrane Library. Gray literature was also searched for relevant papers. Data were extracted from 33 papers, which met eligibility criteria by reporting a computer-based intervention designed to treat substance misuse and mental health in adults. Quality assessments were conducted on these papers.Results: Computer-based interventions generally led to an improvement of substance misuse and mental health outcomes within groups and when compared against waitlist control and psychoeducation. Computer-based interventions were effective at improving dual diagnosis outcomes, and improvements to mental health outcomes specifically were maintained for up to nine months. However, the combined effect of computer-based interventions and therapist support was found to be more effective than the effects of computer-based interventions alone.Conclusions: Many papers were limited by high attrition rates commonly attributed to "digital" interventions. Future research should consider systematically recruiting a range of participants, including those potentially affected by the digital divide, and incorporating methods within research to maintain engagement. This review was also limited by the heterogeneity of the papers reported, many of which differed between targeting dual diagnosis and targeting either substance misuse or mental health respectively, with outcomes investigating other difficulties out of curiosity.

Clinical and cost-effectiveness of guided internet-based interventions in the indicated prevention of depression in green professions (PROD-A): study protocol of a 36-month follow-up pragmatic randomized controlled trial

BACKGROUND

People in green professions are exposed to a variety of risk factors, which could possibly enhance the development of depression. Amongst possible prevention approaches, internet- and mobile-based interventions (IMIs) have been shown to be effective and scalable. However, little is known about the effectiveness in green professions. The aim of the present study is to examine the (cost-)effectiveness of a tailored IMI program for reducing depressive symptoms and preventing the onset of clinical depression compared to enhanced treatment as usual (TAU+).

METHODS

A pragmatic randomized controlled trial (RCT) will be conducted to evaluate a tailored and therapeutically guided preventive IMI program in comparison to TAU+ with follow-ups at post-treatment (9 weeks), 6-, 12-, 24-, and 36-months. Entrepreneurs in green professions, collaborating spouses, family members and pensioners (N = 360) with sufficient insurance status and at least subthreshold depression (PHQ-9 ≥ 5) are eligible for inclusion. Primary outcome is depressive symptom severity (QIDS-SR16). Secondary outcomes include incidence of depression (QIDS-SR16), quality of life (AQoL-8D) and negative treatment effects (INEP). A health-economic evaluation will be conducted from a societal perspective. The IMI program is provided by psychologists of an external service company and consists of six guided IMIs (6-8 modules, duration: 6-8 weeks) targeting different symptoms (depressive mood, depressive mood with comorbid diabetes, perceived stress, insomnia, panic and agoraphobic symptoms or harmful alcohol use). Intervention choice depends on a screening of participants' symptoms and individual preferences. The intervention phase is followed by a 12-months consolidating phase with monthly contact to the e-coach.

DISCUSSION

This is the first pragmatic RCT investigating long-term effectiveness of a tailored guided IMI program for depression prevention in green professions. The present trial builds on a large-scale strategy for depression prevention in green professions. The intended implementation of the IMI program with a nationwide rollout has the potential to reduce overall depression burden and associated health care costs in case of given effectiveness.

Web-based self-help with and without chat counseling to reduce cocaine use in cocaine misusers: Results of a three-arm randomized controlled trial

BACKGROUND

In recent years, cocaine use has increased in many countries, but only a minority of users seek treatment. Cognitive behavioral therapy (CBT) is seen as first-choice face-to-face treatment. However, a web-based intervention might serve as an alternative.

AIMS

To test the efficacy of a web-based self-help intervention, with and without chat counseling, grounded in CBT, at reducing cocaine use in cocaine misusers not in treatment for a substance use disorder.

METHODS

Subjects were randomly assigned to (1) a self-help intervention with chat support, (2) a self-help intervention without chat support, or (3) a waiting list control group. The fully-automated self-help program consisted of eight modules based on motivational interviewing, self-control practices and CBT. The primary outcome was the quantity of cocaine use per week. Secondary outcomes included frequency of cocaine and other substance use and mental health symptoms. Linear regression analysis was performed to investigate changes in primary and secondary outcomes.

RESULTS

In total, 416 users registered online for the trial, of whom 311 completed the baseline assessment. Participants were predominantly male (73%) and averaged 33 years old (SD = 7.6). Despite considerable efforts on our part, only 47 of 311 (15.1%) subjects completed the 6-month follow-up assessment. Frequency of cocaine use and severity of cocaine dependence decreased only in the intervention groups. No significant difference in the primary outcome was observed between the study arms, but several differences in secondary outcomes were observed by complete case analyses.

CONCLUSIONS

Many cocaine misusers from the general population and not otherwise in treatment could be reached and decreased their cocaine use utilizing a CBT-based online intervention. However, due to the high percentage of dropouts and serious difficulties reaching subjects for follow-up assessments, no conclusions can be drawn regarding study arm differences. Implications for future studies are discussed.

Effectiveness of Workplace Intervention for Reducing Alcohol Consumption: a Systematic Review and Meta-Analysis

AIMS

To review the effectiveness of workplace interventions in reducing alcohol consumption among employees.

METHODS

Systematic search of science databases from inception till May 2018 for trials where an intervention was tested against a control and data presented as amount of alcohol consumed per week. Quality of trials was assessed by Cochrane risk of bias tool. Meta-analysis was performed with random-effects model and pooled mean difference (MD) was reported with 95% confidence interval. Publication bias was assessed using Egger's test.

RESULTS

Seven trials with 1291 participants could be included. No outcome assessments were blinded. There was positive effect of workplace intervention on reduction of alcohol consumption with pooled MD of -2.25 [95% CI: -4.20 to -0.30]. The effect was only seen where subjects had a baseline alcohol consumption of over 15 standard drinks per week. There was no heterogeneity across the trials (I2=0%). Funnel plot was symmetrical shaped and Egger's test confirmed that there was no publication bias. Two studies found no advantages to intervention on differences on the AUDIT test.

CONCLUSION

There is weak evidence for workplace interventions (varying modes) as a way of facilitating reduction in the consumption of alcohol among employees but only among the heavier consumers.
