Affected other interventions: a systematic review and meta-analysis across addictions

Community Reinforcement and Family Training versus counselling for parents of treatment-refusing young adults with hazardous substance use: A randomized controlled trial

BACKGROUND AND AIMS

Despite the high prevalence and negative effects of hazardous substance use, few young adults enter treatment. Community Reinforcement and Family Training (CRAFT), a support programme for concerned significant others of people with substance use disorders, has proved efficacious in promoting treatment entry. The aim of the current trial was to compare the efficacy of CRAFT with an active control for parents of young adults (aged 18-24 years) with hazardous substance use.

DESIGN

This was a randomized controlled superiority trial comparing CRAFT (n = 58) with an active control group receiving manualized counselling (n = 55), with outcome assessments at 6, 12 and 24 weeks (primary end-point). A sequential design with a stopping rule was added post recruitment commencement.

SETTING

The study took place in two outpatient clinics for young adults in Stockholm, Sweden, and subsequently via video-conference due to COVID-19.

PARTICIPANTS

Between October 2018 and May 2021, 113 participants (92% female) who were parents of young adults (87% male) were recruited. Recruitment was discontinued when 70% of the planned sample had been recruited, following an interim analysis of the primary outcome showing no difference between conditions.

INTERVENTION AND COMPARATOR

Participants were randomized (ratio 1 : 1) to eight manual-based individual CRAFT sessions or five individual manual-based counselling sessions + one voluntary psychoeducative group session, delivered over maximum 14 weeks.

MEASUREMENTS

The primary outcome measure was the rate of young adult entry in substance use treatment during the trial period (24 weeks).

FINDINGS

At the 24 weeks follow-up, 19 (33%) of CRAFT participants and 17 (31%) of counselling participants had reported young adult treatment entry, with no difference between conditions (odds ratio CRAFT versus counselling 0.84, 95% confidence interval = 0.35; 1.99, P = 0.700). Both conditions reported clinically relevant reductions in young adult substance use, but no change in participants' levels of depression, anxiety or stress.

CONCLUSIONS

This trial showed no statistically significant evidence that Community Reinforcement and Family Training (CRAFT), a support programme for concerned significant others of people with substance use disorders, is more efficacious than manual-based counselling regarding treatment entry for young adults.

The Efficacy of Psychosocial Interventions in Minimising the Harm Caused to Affected Others of Problem Gambling: A Systematic Review and Meta-Analysis

Problem gambling not only impacts gamblers but also protrudes onto several affected others who experience adverse impacts, including financial, health, relationships, and psychological problems. The aims of this systematic review were twofold; to identify the psychosocial interventions to minimise the harm caused to affected others of problem gambling and to assess their efficacy. This study was conducted as outlined in the research protocol PROSPERO (CRD42021239138). Database searches were conducted in CENTRAL, MEDLINE, Social Science Database, CINHAL Complete, Academic Search Ultimate and PsycINFO. Randomised controlled trials of psychosocial interventions that aimed to minimise the harm caused to affected others of problem gambling written in English were eligible for inclusion. Risk of bias for included studies was assessed using the Cochrane ROB 2.0 tool. The identified interventions focused on two approaches to supporting affected others: interventions involving both the problem gambler and affected others, and interventions involving affected others only. As the interventions and outcome measures used were sufficiently similar, a meta-analysis was conducted. The quantitative synthesis revealed that generally, treatment groups were unable to show greater benefits over control groups. The goal for future interventions aimed at affected others of problem gambling should focus primarily on the wellbeing of affected others. The standardisation of outcome measures and data collection time points for better comparison of future research is needed.

Psychological intervention for gambling disorder: A systematic review and meta-analysis

Background and aims

Increasingly, gambling features migrate into non-gambling platforms (e.g., online gaming) making gambling exposure and problems more likely. Therefore, exploring how to best treat gambling disorder (GD) remains important. Our aim was to review systematically and quantitatively synthesize the available evidence on psychological intervention for GD.

Methods

Records were identified through searches for randomized controlled trials (RCTs) evaluating psychological intervention for GD via six academic databases without date restrictions until February 3, 2023. Study quality was assessed with the revised Cochrane risk-of-bias tool for randomized trials (RoB2). Primary outcomes were GD symptom severity and remission of GD, summarized as Hedges' g and odds ratios, respectively. The study was preregistered in PROSPERO (#CRD42021284550).

Results

Of 5,541 records, 29 RCTs (3,083 participants analyzed) were included for meta-analysis of the primary outcomes. The efficacy of psychological intervention across modality, format and mode of delivery corresponded to a medium effect on gambling severity (g = -0.71) and a small effect on remission (OR = 0.47). Generally, risk of bias was high, particularly amongst early face-to-face interventions studies.

Discussion and conclusions

The results indicate that psychological intervention is efficacious in treating GD, with face-to-face delivered intervention producing the largest effects and with strongest evidence for cognitive behavioral therapy. Much remains to be known about the long-term effects, and investigating a broader range of treatment modalities and digital interventions is a priority if we are to improve clinical practice for this heterogeneous patient group.

Congruence couple therapy for alcohol use and gambling disorders with comorbidities (part I): Outcomes from a randomized controlled trial

A nonblinded randomized trial was conducted at two Canadian provincial outpatient addiction clinics that tested the effectiveness of a systemic congruence couple therapy (CCT) versus individual-based treatment-as-usual (TAU) on nine clinical outcomes: (1) primary outcomes-alcohol use and gambling, psychiatric symptoms, and couple adjustment; (2) secondary outcomes-emotion regulation, substance use, depression, post-traumatic stress symptoms, and life stress. Data of primary clients and partners (N = 46) were analyzed longitudinally across baseline, posttreatment (5 months), and follow-up (8 months). Alcohol use disorder (95%) and gambling disorder (5%) were in the severe range at baseline, and co-addiction was 27%. Psychiatric comorbidity was 100%, and 18% of couples were jointly addicted. Between-group comparison favored CCT in primary outcomes with medium-to-large effect sizes (Cohen's h = 0.74-1.44). Secondary outcomes were also significantly stronger for CCT (Cohen's h = 0.27-1.53). Within-group, for all primary outcomes, a significant proportion of symptomatic CCT clients and partners improved, converging with ANOVA results of large effect sizes (0.14-0.29). All secondary outcomes improved significantly in CCT with large effect sizes (0.14-0.50). TAU showed significant within-group improvement in alcohol use, other substance use, and life stress with large effect sizes (0.16-0.40). Primary clients and partners made largely equivalent improvement within CCT and within TAU. Results were triangulated with clients' satisfaction ratings and counselors' reports. Overall, significant within-group effects were detected for CCT both clinically and statistically and between-group difference favored CCT. Future trials are required to validate these promising findings.

Effective behaviour change techniques for family and close friends: A systematic review and meta-analysis across the addictions

This systematic review aimed to determine whether the use of specific behaviour change technique (BCT) groups are associated with greater effectiveness for psychosocial interventions delivered to family and close friends (FCFs) impacted by addiction. A systematic search of peer-reviewed and grey literature published until August 2021 identified 32 studies in 38 articles. An established BCT taxonomy (93 BCTs clustered into 16 groups) was adapted (inclusion of seven additional BCT groups) and applied to 57 interventions. The meta-analyses indicated that some, but not all, FCF outcomes were improved by the exclusion of BCTs within several groups (Reward and Threat, Scheduled Consequences, Confrontation of the Addicted Person to Engage in Treatment, and Goals and Planning) and inclusion of BCTs within the Restoring a Balanced Lifestyle group. Addicted person outcomes were improved by the inclusion of some BCTs within several groups (Repetition and Substitution, Reward and Threat, Scheduled Consequences, and Restoring a Balanced Lifestyle). Relationship functioning outcomes were improved by the inclusion of BCTs within the Confrontation of the Addicted Person to Engage in Treatment group. Future research involving the development and evaluation of numerous interventions or comprehensive multi-component interventions that can address the various needs of FCFs, without counteracting them, is required.

The effectiveness of psychosocial interventions for family members impacted by another's substance use: A systematic review and meta-analysis

INTRODUCTION

Family members affected by another's substance use disorder experience physical health problems, breakdowns in relationships and reduced psychological wellbeing. This review examines the effectiveness of psychosocial interventions for improving the wellbeing of family members.

METHODS

A systematic review of randomised-controlled trials (RCT), non-RCTs and pre-post studies examining group or individual interventions for affected families. Five databases were searched (PubMed, PsycINFO, Medline, Web of Science, Cochrane Library). Outcomes included psychological functioning, quality of life, physical health and substance use, family functioning and coping. Outcomes were analysed by study design and mode of delivery (individual or group). Risk of bias was assessed using the Cochrane tools (RoB2, ROBINS-I). The review followed PRISMA reporting guidelines and was prospectively registered with the PROSPERO database (CRD42020200260).

RESULTS

Nineteen studies were included (k = 10 included in meta-analyses). In k = 3 RCTs, individually administered interventions significantly reduced depression (standardised mean difference [SMD] 0.50, 95% confidence interval [CI] 0.21, 0.79) and distress (SMD 0.28, 95% CI 0.03, 0.54). In k = 2 pre-post studies, individual interventions improved family functioning (d = 0.51, 95% CI 0.28, 0.73) and coping (d = 0.43, 95% CI 0.24, 0.61). In k = 3 non-RCTs and k = 2 pre-post designs group interventions significantly reduced depression (d = 0.50, 95% CI 0.17, 0.82) and distress (d = 0.44, 95% CI 0.13, 0.75), and improved coping (d = 0.81, 95% CI 0.29, 1.33).

DISCUSSION AND CONCLUSIONS

This review summarises the contemporary literature evaluating interventions for affected families, with both individual and group interventions demonstrating favourable outcomes. However, small sample sizes and methodologically weak-quality studies limit conclusions.

The Practice and Feasibility of Screening, Treatment, and Referral for Gaming Problems in Gambling, Alcohol and Other Drugs, and Youth Services

Screening, brief intervention, and referral to treatment (SBIRT) is a comprehensive approach to identifying people at risk of addiction, but its feasibility for gaming disorder is unknown. This study surveyed 88 clinicians from gambling, alcohol and other drugs, and youth services in New Zealand. Results indicated that the most frequent GD screening method was an unstructured interview (61%), but 74% stated they would use a standardized tool if available. Responsivity to the detection of GD was an immediate intervention (84%), and rates of referral were low (28%). Around 50% of clinicians indicated high confidence in administering motivational approaches and relapse prevention. There was strong support for screening training (85%), treatment guidelines (88%), self-help materials (92%), and access to internet-delivered CBT that could be used in conjunction with other treatment (84%). Clinicians appear motivated and willing to implement SBIRT for GD but report lacking necessary training and resources, including access to screening tools and treatment guidelines.

Closing the treatment gap for alcohol use disorders in low- and middle-income countries

The alcohol-attributable disease burden is greater in low- and middle-income countries (LMICs) as compared to high-income countries. Despite the effectiveness of interventions such as health promotion and education, brief interventions, psychological treatments, family-focused interventions, and biomedical treatments, access to evidence-based care for alcohol use disorders (AUDs) in LMICs is limited. This can be explained by poor access to general health and mental health care, limited availability of relevant clinical skills among health care providers, lack of political will and/or financial resources, historical stigma and discrimination against people with AUDs, and poor planning and implementation of policies. Access to care for AUDs in LMICs could be improved through evidence-based strategies such as designing innovative, local and culturally acceptable solutions, health system strengthening by adopting a collaborative stepped care approach, horizontal integration of care into existing models of care (e.g., HIV care), task sharing to optimise limited human resources, working with families of individuals with AUD, and leveraging technology-enabled interventions. Moving ahead, research, policy and practice in LMICs need to focus on evidence-based decision-making, responsiveness to context and culture, working collaboratively with a range of stakeholders to design and implement interventions, identifying upstream social determinants of AUDs, developing and evaluating policy interventions such as increased taxation on alcohol, and developing services for special populations (e.g., adolescents) with AUDs.

Gambling-related harms to concerned significant others: A national Australian prevalence study

Background and aims

Gambling-related harm to concerned significant others (CSOs) is an important public health issue since it reduces CSOs' health and wellbeing in numerous life domains. This study aimed to 1) estimate the first national prevalence of CSOs harmed by gambling in Australia; 2) identify the characteristics of CSOs most at risk of harm from another person's gambling; 3) compare the types and number of harms experienced by CSOs based on their relationship to the person who gambles; and 4) compare the number of harms experienced by CSOs by self-identified gender.

Methods

Based on a national CATI survey weighted to population norms, 11,560 respondents reported whether they had been personally and negatively affected by another person's gambling in the past 12 months; and if so, answered detailed questions about the harms experienced from the person's gambling who had harmed them the most.

Results

Past-year prevalence of gambling-related harm to adult Australian CSOs was (6.0%; 95% CI 5.6%-6.5%). CSOs most commonly reported emotional harms, followed by relationship, financial, health and vocational harms, respectively. Former partners reported the most harm, followed by current partners, other family members and non-family members, respectively. Female CSOs were more likely to report more harm and being harmed by a partner or other family member, and male CSOs from a non-family member.

Discussion and conclusions

The findings provide new insights into the wider societal burden of gambling and inform measures aimed at reducing harm to CSOs from gambling and supporting them to seek help.
