Are we making Inroads? A randomized controlled trial of a psychologist-supported, web-based, cognitive behavioral therapy intervention to reduce anxiety and hazardous alcohol use among emerging adults

Psychological mechanisms of change in reducing co-occurring social anxiety and alcohol use: A causal mediation analysis of the online Inroads intervention

BACKGROUND

Research has documented the prevalence and treatment of co-occurring anxiety and alcohol use, but the mechanisms underlying treatment efficacy, especially in online interventions, remain unclear. This study investigated the potential behavioral, cognitive, and motivational mechanisms mediating the effectiveness of 'Inroads,' the first online early intervention for co-occurring anxiety and hazardous alcohol use in young adults.

METHODS

Data from an Australian randomized controlled trial with 123 participants aged 17-24 (M = 21.6) was used. Causal multiple mediation analysis tested whether improvements in social anxiety symptoms could jointly be attributable to reductions in maladaptive emotion regulation and alcohol use, and whether reductions in alcohol use (mean drinks per day) could jointly be attributable to reductions in maladaptive emotion regulation, alcohol motives (drinking to cope with anxiety and for enhancement), and alcohol outcome expectancies (tension reduction and social lubrication).

RESULTS

The results did not support a joint mediated effect for the hypothesized mechanisms in the social anxiety or alcohol use model.

CONCLUSIONS

Additional research is required to further understand the specific mechanisms, driving reductions in social anxiety and alcohol use within integrated treatments. This is especially true for social anxiety where, there was no evidence to suggest that the hypothesized mediators contributed to change in social anxiety symptoms.

A Brief Cognitive Behavioral Therapy-Based Digital Intervention for Reducing Hazardous Alcohol Use in South Korea: Development and Prospective Pilot Study

Background

Alcohol consumption is a leading cause of death and disability worldwide, associated with numerous acute and chronic medical conditions. Digital health interventions offer a promising solution to overcome barriers associated with traditional treatment methods, providing accessible, scalable, and cost-effective means to support individuals in reducing hazardous drinking.

Objective

This pilot study aims to evaluate the feasibility, acceptability, and preliminary efficacy of the Sober smartphone app in individuals with hazardous alcohol use.

Methods

This single-group, pre- and postpilot study included 20 participants with risky alcohol use, identified using the Alcohol Use Disorder Identification Test. Participants used the Sober app for 4 weeks, incorporating cognitive behavioral therapy-based interventions. Feasibility was assessed by study and session completion rates, acceptability by participant satisfaction and perceived usefulness, and preliminary efficacy by changes in alcohol consumption and psychiatric symptoms. Semistructured interviews with participants and clinicians provided qualitative perspectives on the app's usability, efficacy, and areas for improvement.

Results

Of the 20 enrolled participants, 17 completed the study. The app demonstrated high feasibility with an 85% (17/20) study completion rate, and 59% (10/17) completed all cognitive behavioral therapy sessions. Participants reported positive acceptability, with average satisfaction and usefulness ratings of 3.8 and 3.7 of 5, respectively. Preliminary efficacy outcomes showed significant improvements: abstinence days increased from 67% to 85% (z=-3.17; P=.002), heavy drinking episodes decreased from 3.3 to 1.9 (t16=-2.97; P=.003), and total alcohol consumption reduced from 456.8 to 195.9 mL (t16=3.16; P=.002). Alcohol Use Disorder Identification Test scores dropped from 17.5 to 10.7 (t16=4.51; P<.001). Additionally, depression (Patient Health Questionnaire-9) scores decreased from 5.8 to 4.4 (t16=2.91; P=.01), and anxiety (Generalized Anxiety Disorder-7) scores from 3.4 to 2.1 (z=-2.80; P=.005). No adverse events were reported. Qualitative analysis found participants valued daily logging but noted usability issues, while clinicians called for tailored goals, enhanced communication features, and age-specific content.

Conclusions

The mobile app Sober shows promise as an effective tool for reducing hazardous alcohol consumption and improving related psychiatric symptoms. The study demonstrated high feasibility and positive acceptability, with significant preliminary efficacy in reducing alcohol use. Qualitative findings provided actionable evidence for refining the app's usability and clinical integration. Further research through a randomized controlled trial is warranted to confirm these findings and optimize the app's features and content.

Web-based intervention for young adults experiencing anxiety and hazardous alcohol use: Study protocol for an 18-month randomized controlled trial

BACKGROUND AND AIMS

Alcohol use and anxiety often co-occur, causing increased severity impairment. This protocol describes a randomized controlled trial (RCT) that aims to test the efficacy and cost-effectiveness of a web-based, self-guided alcohol and anxiety-focused program, compared with a web-based brief alcohol-focused program, for young adults who drink at hazardous levels and experience anxiety. It will also test moderators and mechanisms of change underlying the intervention effects.

DESIGN

This RCT will be conducted with a 1:1 parallel group.

SETTING

The study will be a web-based trial in Australia.

PARTICIPANTS

Individuals aged 17-30 years who drink alcohol at hazardous or greater levels and experience at least mild anxiety (n = 500) will be recruited through social media, media (TV, print) and community networks.

INTERVENTION AND COMPARATOR

Participants will be randomly allocated to receive a web-based, integrated alcohol-anxiety program plus technical and motivational telephone/e-mail support (intervention) or a web-based brief alcohol-feedback program (control).

MEASUREMENTS

Clinical measures will be assessed at baseline, post-intervention (2 months), 6 months (primary end-point), 12 months and 18 months. Co-primary outcomes are hazardous alcohol consumption and anxiety symptom severity. Secondary outcomes are binge-drinking frequency; alcohol-related consequences; depression symptoms; clinical diagnoses of alcohol use or anxiety disorder (at 6 months post-intervention), health-care service use, educational and employment outcomes; and quality of life. Mediators and moderators will also be assessed. Efficacy will be tested using mixed models for repeated measures within an intention-to-treat framework. The economic evaluation will analyze individual-level health and societal costs and outcomes of participants between each trial arm, while mediation models will test for mechanisms of change.

COMMENTS

This will be the first trial to test whether a developmentally targeted, web-based, integrated alcohol-anxiety intervention is effective in reducing hazardous alcohol use and anxiety severity among young adults. If successful, the integrated alcohol-anxiety program will provide an accessible intervention that can be widely disseminated to improve wellbeing of young adults, at minimal cost.

Outcomes of Best-Practice Guided Digital Mental Health Interventions for Youth and Young Adults with Emerging Symptoms: Part II. A Systematic Review of User Experience Outcomes

Although many young people demonstrate resilience and strength, research and clinical evidence highlight an upward trend in mental health concerns among those aged 12 to 25 years. Youth-specific digital mental health interventions (DMHIs) aim to address this trend by providing timely access to mental health support for young people (12-25 years). However, there is a considerable gap in understanding young people user experiences with digital interventions. This review, co-designed with Australia's leading mental health organization Beyond Blue, utilizes a systematic methodology to synthesize evidence on user experience in youth-oriented digital mental health interventions that are fully or partially guided. Five relevant online databases were searched for articles published from 2018 to 2023, yielding 22,482 articles for screening and 22 studies were included in the present analysis. User experience outcomes relating to satisfaction and engagement were assessed for each included intervention, with experience indicators relating to usefulness, usability, value, credibility, and desirability being examined. Elements associated with positive/negative outcomes were extracted. Elements shown to positively influence user experience included peer engagement, modern app-based delivery, asynchronous support, and personalized content. In contrast, users disliked static content, homework/log-keeping, the requirement for multiple devices, and social media integration. Asynchronous interventions showed high satisfaction but faced engagement issues, with combined asynchronous/synchronous interventions reporting better completion rates. DMHIs offer a promising platform for youth mental health support and has the potential to dramatically increase the reach of interventions through the adoption of technological and user experience best practices. While young people respond positively to many aspects of intervention modernization, such as interactive, app-based design, other concepts, such as social media integration, they need to be adopted by the field more cautiously to ensure trust and engagement.Trial Registration CRD42023405812.

Outcomes of Best-Practice Guided Digital Mental Health Interventions for Youth and Young Adults with Emerging Symptoms: Part I. A Systematic Review of Socioemotional Outcomes and Recommendations

Youth-specific digital mental health interventions (DMHI) represent an emerging field of study, and aim to increase access, improve socioemotional outcomes, and, where required, support triage to targeted interventions. However, prior reviews have reported inconsistent findings on the clinical effectiveness of such interventions in young adults (12-25 years). Further, shortfalls remain for the impact of guided interventions based on the mode of delivery and the type of human support personnel (e.g., professional or peer) guiding the intervention. In response, this systematic review, co-designed with Australia's leading mental health organization, aims to assess the effectiveness of guided digital programs in improving youth socioemotional outcomes. Included studies involve young people experiencing mental ill-health, receiving brief (i.e., 1-12 sessions), digitally delivered (at least partially) psychological interventions that were guided or partially guided, tested in a type of experimental study, with a socioemotional outcome. Specific socioemotional outcomes examined were depression, anxiety, stress, wellbeing, mindfulness, and quality of life. A systematic search of the contemporary published and grey literature identified 22,482 records with 32 relevant records published between 2018 and 2023. A narrative synthesis guided integration of findings. Results demonstrated strong evidence for the effectiveness of guided interventions on socioemotional outcomes (i.e., depression, anxiety, stress) yet these effects were short-lived. When factoring in the use of different control groups (i.e., active vs. inactive), inconsistent effects were observed for the socioemotional outcomes of depression, anxiety, and stress. The mode of delivery (i.e., asynchronous, synchronous, combined) and the type of human support personnel did not appear to impact socioemotional outcomes. Results indicate efficacious brief digital interventions for depression and anxiety include refresher/follow-up content, goal setting content, and relapse prevention content. In contrast, poor efficacy is associated with interventions that include homework tasks, self-monitoring, and log-keeping content.PROSPERO, ID CRD42023405812.

Self-compassion and avoidant coping as mediators of the relationship between childhood maltreatment and mental health and alcohol use in young adulthood

BACKGROUND

Exposure to childhood maltreatment increases the risk of mental health and substance use problems. Understanding the mechanisms linking maltreatment to these problems is critical for prevention.

OBJECTIVE

To examine whether self-compassion and avoidant coping mediate the relationship between childhood maltreatment and mental ill-health and alcohol use.

PARTICIPANTS AND SETTING

Australians aged 18-20 years at baseline were recruited through social media and professional networks.

METHODS

Participants (n = 568) completed an online survey, and were followed up annually for two subsequent surveys. Mediation models were conducted with the SPSS PROCESS macro. Maltreatment was the predictor; Wave 2 self-compassion and avoidant coping as mediators; Wave 3 mental health and alcohol use as outcomes.

RESULTS

Childhood maltreatment predicted greater mental health symptoms (b = 0.253, 95 % CI = 0.128-0.378), and alcohol use (b = 0.057, 95 % CI = 0.008-0.107). Both self-compassion (b = 0.056, 95 % CI = 0.019-0.093) and avoidant coping (b = 0.103, 95 % CI = 0.024-0.181) mediated the relationship between maltreatment and mental health. Additionally, avoidant coping, but not self-compassion, mediated the relationship (b = 0.040, 95 % CI 0.020-0.061) with alcohol use. However, when controlling for pre-existing mental health and substance use, neither self-compassion nor avoidant coping mediated the relationship with mental health. Only avoidant coping mediated the link with alcohol use (b = 0.010, 95 % CI = 0.001-0.020).

CONCLUSIONS

Findings suggests that by adulthood, self-compassion and avoidant coping may not explain future change in mental health symptoms; however, avoidant coping accounts for change in alcohol use across early adulthood. Reducing avoidant coping may prevent hazardous alcohol use across young adulthood among people exposed to childhood maltreatment.

Web-Based Cognitive Bias Modification Program for Young People With Social Anxiety and Hazardous Alcohol Use: Feasibility, Acceptability, and Preliminary Efficacy Study

BACKGROUND

Interpretation bias modification (IBM) and approach bias modification (ApBM) cognitive retraining interventions can be efficacious adjunctive treatments for improving social anxiety and alcohol use problems. However, previous trials have not examined the combination of these interventions in a young, comorbid sample.

OBJECTIVE

This study aims to describe the feasibility, acceptability, and preliminary efficacy of a web-based IBM+ApBM program for young adults with social anxiety and hazardous alcohol use ("Re-Train Your Brain") when delivered in conjunction with treatment as usual (TAU).

METHODS

The study involved a 3-arm randomized controlled pilot trial in which treatment-seeking young adults (aged 18-30 y) with co-occurring social anxiety and hazardous alcohol use were randomized to receive (1) the "integrated" Re-Train Your Brain program, where each session included both IBM and ApBM (50:50 ratio), plus TAU (35/100, 35%); (2) the "alternating" Re-Train Your Brain program, where each session focused on IBM or ApBM in an alternating pattern, plus TAU (32/100, 32%); or (3) TAU only (33/100, 33%). Primary outcomes included feasibility and acceptability, and secondary efficacy outcomes included changes in cognitive biases, social anxiety symptoms, and alcohol use. Assessments were conducted at baseline, after the intervention period (6 weeks after baseline), and 12 weeks after baseline.

RESULTS

Both Re-Train Your Brain program formats were feasible and acceptable for young adults. When coupled with TAU, both integrated and alternating programs resulted in greater self-reported improvements than TAU only in anxiety interpretation biases (at the 6-week follow-up; Cohen d=0.80 and Cohen d=0.89) and comorbid interpretation biases (at the 12-week follow-up; Cohen d=1.53 and Cohen d=1.67). In addition, the alternating group reported larger improvements over the control group in generalized social anxiety symptoms (at the 12-week follow-up; Cohen d=0.83) and alcohol cravings (at the 6-week follow-up; Cohen d=0.81). There were null effects on all other variables and no differences between the intervention groups in efficacy outcomes.

CONCLUSIONS

Should these findings be replicated in a larger randomized controlled trial, Re-Train Your Brain has the potential to be a scalable, low-cost, and non-labor-intensive adjunct intervention for targeting interpretation and comorbidity biases as well as generalized anxiety and alcohol-related outcomes in the real world.

Integrated care – panacea or white elephant? A review of integrated care approaches in Australia over the past two decades

Purpose

Integrated care is widely supported as a means of improving treatment outcomes for people with co-occurring mental health and substance use disorders. Over the past two decades, Australian state and federal governments have identified integrated care as a policy priority and invested in a number of research and capacity building initiatives. This study aims to examine Australian research evaluating the effectiveness of integrated treatment approaches to provide insight into implications for future research and practice in integrated treatment.

Design/methodology/approach

This narrative review examines Australian research evaluating empirical evidence of the effectiveness of integrated treatment approaches within specific populations and evidence from initiatives aimed at integrating care at the service or system level.

Findings

Research conducted within the Australian context provides considerable evidence to support the effectiveness of integrated approaches to treatment, particularly for people with high prevalence co-occurring disorders or symptoms of these (i.e. anxiety and depression). These have been delivered through various modalities (including online and telephone-based services) to improve health outcomes in a range of populations. However, there is less evidence regarding the effectiveness of specific models or systems of integrated care, including for more severe mental disorders. Despite ongoing efforts on behalf of the Australian government, attempts to sustain system-level initiatives have remained hampered by structural barriers.

Originality/value

Effective integrated interventions can be delivered by trained clinicians without requiring integration at an organisational or structural level. While there is still considerable work to be done in terms of building sustainable models at a system level, this evidence provides a potential foundation for the development of integrated care models that can be delivered as part of routine practice.

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.
