Abstract This chapter synthesises the current body of research on peer support within mental health, exploring its established strengths and acknowledging potential risks associated with its implementation. Peer support, defined by the provision of mutuality and shared understanding between individuals with lived experience of mental health challenges, has garnered increasing attention as a valuable component of recovery-oriented care. This chapter delves into the unique expertise derived from lived experience, highlighting how it fosters empathy, hope and a sense of belonging often distinct from traditional clinical approaches. Evidence supporting the complementary nature of peer support alongside traditional services is examined, showcasing its potential to improve overall personal recovery. Nevertheless, this chapter also critically addresses the potential risks and challenges identified in the literature. These include issues related to role ambiguity for peer support workers within multidisciplinary teams, difficulties in successful integration and sustainable implementation within diverse mental health settings and the importance of adequate training, supervision and clear ethical guidelines. Furthermore, this chapter explores potential risks for both peer support workers and recipients, such as emotional burden, boundary challenges and the need for careful consideration of power dynamics. By providing a balanced overview of the existing research, this chapter aims to offer a nuanced understanding of peer support’s contribution to mental health care. It underscores the significant benefits of leveraging lived experience while emphasising the crucial need for ongoing research, robust implementation strategies and careful attention to potential risks to ensure the safe and effective delivery of peer support interventions that truly promote recovery and well-being. Ultimately, this chapter advocates for a thoughtful and evidence-informed approach to integrating peer support as a vital element within comprehensive mental health systems.

BACKGROUND:Post-migration stressors can exacerbate post-traumatic stress disorder (PTSD) and reduce treatment effectiveness among refugees. Evidence for integrated care models in high-income settings remains limited. AIMS:To compare treatment as usual (TAU) with an add-on integrated care intervention for unemployed refugees with PTSD. METHOD:We conducted a two-arm, parallel-group superiority trial with 1:1 randomisation to TAU or TAU with an add-on integrated care intervention, delivered at a specialised out-patient clinic in Denmark (ClinicalTrials.gov NCT04244864). TAU included sessions with a psychologist and physician over 8-12 months. The integrated care intervention also included structured collaboration with employment services. The primary outcome was functioning, using the 12-item World Health Organization Disability Assessment Schedule 2.0 (WHODAS) interview. Secondary outcomes included symptoms, quality of life and post-migration stressors. Analyses followed the intention-to-treat principle, using analysis of covariance and linear regression with multiple imputations. RESULTS:The study included 195 patients in treatment from 2020 to 2025. No difference was observed in WHODAS score between groups pre- to post-treatment (mean difference 0.30, 95% CI -2.40 to 3.00; P = 0.825). Similarly, no differences were found for secondary or exploratory outcomes, and overall change was limited. However, the integrated care group had a lower rate of early dropout (P = 0.042) and higher level of treatment satisfaction (P = 0.035). CONCLUSIONS:Integrated care was feasible but not superior to TAU in improving outcomes for refugees with longstanding symptoms and unemployment. Future research should examine how the timing and intensity of integrated care interventions influence outcomes, including earlier implementation and adequate support for refugees with longstanding and complex needs.

Background Mental disorders and functional somatic disorder (FSD) often co-occur, but longitudinal population-based studies examining their temporal associations remain scarce. The objectives of this study were 1) to investigate the association between mental disorders and FSD in the baseline investigation of a randomly selected population-based cohort, and 2) to investigate whether mental disorders were risk factors for newly developed (incident) FSD over a 5-year period. Methods The DanFunD baseline and 5-year follow-up (FU) investigations were used. FSD comprised the outcome variables and was established at both baseline and FU with validated symptom questionnaires and diagnostic interviews. Psychiatric discharge diagnoses and prescription psychoactive medication were exposure variables and were obtained from comprehensive Danish Central Registries in a period of 10 years before study inclusion. Prevalence odds ratios (PORs) and odds ratios (ORs) with 95% confidence intervals (CIs) were measures of association. People with lived experience of FSD were not involved in the research and writing process. Results A total of 9,656 individuals participated in the DanFunD baseline cohort (53.9% women, median age 54 years, interquartile range (IQR): 44–64 years) and 5,738 individuals participated in the 5-year FU cohort (53.3% women, median age 55 years, IQR: 47–64 years). Having received a diagnosis of a mental disorder or having received prescription psychoactive medication 10 years before baseline were strongly associated with both questionnaire-based FSD (POR = 2.54, 95% CI: 2.22–2.90) and interview-diagnosed FSD (POR = 1.81, 95% CI: 1.37–2.39) at DanFunD baseline. Likewise, it was a significant risk factor for having developed FSD at FU for questionnaire-based FSD (OR = 1.60, 95% CI: 1.24–2.05). However, for interview-diagnosed FSD, a significant association could not be found (OR = 1.14, 95% CI: 0.54–2.41). Conclusions The study indicates that mental disorders may be risk factors for developing FSD. The findings suggest that effective management of mental disorders may help lower the risk of subsequent FSD, emphasizing the importance of accurate diagnosis and coordinated care across clinical services. They also point to preventive opportunities, where early psychological or stress-management interventions may benefit individuals at elevated risk.

Most research on youth mental health services has focused on clinical treatments and therapeutic approaches. Given the increasing prevalence of poor mental health among children and adolescents, there is a growing need to broaden this focus and explore the role of the civic sector in supporting young people with mental health issues. This study investigated young people´s experiences with headspace Denmark, a national civil society initiative promoting youth mental health and well-being. Individual semi-structured interviews were conducted with 13 young people aged 14-25 years, who sought support from volunteer counsellors at headspace Denmark and analysed following Braun and Clarke's reflexive thematic analysis. Participants described headspace as a safe and welcoming space where they could share thoughts and feelings that were difficult to express elsewhere. Counsellors were perceived as caring, attentive, and genuinely interested: Conversations were often compared to supportive interactions with friends or family members. The physical environment was described as cozy and home-like, providing a contrast to clinical settings. Findings suggest that volunteer-based mental health services offer distinct benefits beyond compensating for limited professional resources, providing relational, accessible, non-clinical support that may play a valuable role in the broader youth mental health landscape.

Lived experience-led mental health research remains marginalized despite policy calls for recognition and inclusion. The co-produced ‘Paths to Everyday life’ (PEER) trial showed that group-based peer support improves personal recovery, functioning and quality of life in community settings yet faced epistemic biases favoring clinical or service-defined outcomes, ethics restrictions on peer facilitation, and rejections from high-impact journals. This commentary urges funders, editors, and ethics bodies to promote power-sharing, user-defined measures like empowerment, and community-driven trials for equitable, sustainable mental health research and care.

Children of parents with mental illness face significant increased risks of developing mental health problems and experiencing developmental delays or other negative life outcomes due to genetic and environmental factors. Parental symptoms often disrupt caregiving, leading to family stress, inadequate routines, and insufficient stimulation and support in the home. Research, including findings from the Danish High Risk and Resilience Study, the VIA cohort, has shown substantial developmental, social, and cognitive challenges in these children. This study aims to evaluate the efficacy of a team-based, multidisciplinary preventive intervention compared with standard treatment for families with recent parental mental illness via a series of predefined outcome measures. This randomized controlled trial, VIA Family 2.0, includes 304 children aged 3–17 years and 128 children aged 0–2 years with a parent with a psychiatric diagnosis and having received treatment within the past three years. The families will be assessed at baseline and thereafter randomized to either treatment as usual or VIA Family 2.0 intervention. The intervention group will be assigned to a multidisciplinary team with expertise from municipal services, child and adolescent psychiatry, and adult psychiatry. A case manager coordinates all the elements and supports the family with their challenges, on the basis of their own motivation. The study period is 24 months, and all participants will be assessed at baseline and after 24 months. The primary outcomes are cognitive, language and motor development for infants and toddlers aged 0–2 years (Bayley-4, Bayley Scales of Infant and Toddler Development), well-being and behavioral and social development for children aged 3–17 years (the Strengths and Difficulties Questionnaire (SDQ)), perceived parental stress for parents (Parental Stress Scale, PSS), and family functioning for the family (Family Assessment Device, FAD). This study examines the impact of a cross-sectoral intervention that integrates expertise across sectors. This study contributes critical knowledge about whether improving family resilience, supporting children’s development, and reducing risk loads through holistic family support is possible. This research highlights the potential of preventive public health initiatives to promote well-being and reduce long-term adverse outcomes in a high-risk group of children and adolescents. The study is registered at ClinicalTrials.Gov (NCT06312410) on March 15, 2024.

Background: Refugees resettled in high-income countries are at high risk of post-traumatic stress disorder (PTSD) and often face multiple post-migration stressors that can influence symptom severity. While individual and cumulative effects of these stressors have been examined, little is known about how they interact and change during treatment.Objective: To investigate changes in the structure and interconnections of post-migration stressors among refugees with PTSD before and after mental health treatment.Method: Participants were refugees with PTSD receiving multidisciplinary treatment at a specialised mental health clinic in Denmark, as part of a randomised controlled trial. The Post-Migration Living Difficulties Checklist (17-item Danish version) (PMLD) was completed pre- and post-treatment. Partial correlation networks were estimated for each time point, with network comparison test assessing changes in global network connectivity. Predictability of individual stressors and paired-sample t-tests for item-level change were also conducted.Results: Global network connectivity increased significantly from pre- to post-treatment (p = .004), suggesting stronger interrelations among stressors over time. Overall PMLD score did not change from pre- to post-treatment, but on item-level, financial and housing-related stress decreased (p = .006; p = .028), while concerns about returning to the country of origin in an emergency increased (p = .028).Discussion: Post-migration stressors became more interconnected during treatment, underscoring the need to address them not as isolated issues but as interdependent, mutually reinforcing challenges shaped by cultural and structural contexts. Clinically, effective support for trauma-affected refugees requires multi-level interventions that integrate legal, social, and economic determinants alongside mental health care.

Peers with lived experiences of being in recovery of mental health difficulties volunteering in non-governmental organizations (NGOs) to engage in peer support show significant promise in supporting personal recovery for individuals with similar mental health difficulties. “The ‘Paths to Everyday Life’ (PEER) intervention was evaluated in a randomized trial during 2020–2022. As part of a process evaluation, qualitative studies were conducted to explore the perspectives of both recipients and facilitators of the community-based peer support. This qualitative study, underpinned by critical realism, examined how the delivery of the intervention is achieved, the training, and the working conditions from the perspective of the peers volunteering in the NGO operating the project. Nine peer volunteers were recruited for two focus groups (n = 8) and a telephone-based interview (n = 1). The semi-structured realist inspired interviews were audio recorded and transcribed verbatim. The analysis was guided by reflective thematic analysis and through an abductive framework based on knowledge in the field and the PEER intervention context. Data were coded and analysed in Nvivo software version 1.7 (QSR International). Two overarching themes were identified: (1) ‘The contradictory dual role of facilitating groups and sharing equally’; (2) ‘Equipped to facilitate groups’, as well as several sub-themes. In addition, a minor theme has been identified: (3) ‘Volunteer one-on-one peer support is unscripted’. Peer volunteers providing group-based peer support in the community show significant promise. Training in trauma-informed, structured formats and fostering equal, reciprocal relationships among peer co-facilitators and participants greatly enhanced group impact. The organizational support and supervision enhanced peer volunteers’ preparedness for co-facilitation roles, yet the one-on-one peer support for community engagement, sought by only a few participants, requires further clarification and exploration.

Introduction: To our knowledge, no research has reported long‐term follow‐up results from studies comparing collaborative care to consultation liaison in general practice. We have earlier reported 6‐month follow‐up. In this article, we report the 18‐month follow‐up results from the two Danish Collabri Flex studies. Methods: We compared collaborative care to consultation liaison in two randomized controlled trials for persons with anxiety disorders and depression, respectively. Both interventions sought to improve the quality of depression and anxiety care, but they differed in the extent mental health specialists were involved. As part of the consultation liaison intervention, psychiatrists and care managers could provide advice and suggestions to the general practitioner (GP). In the collaborative care intervention, psychiatrists and care managers could provide advice and suggestions, and care managers could help the GP manage patient care. 18 months after randomization, we collected follow‐up data. Outcomes included anxiety symptoms (BAI), depression symptoms (BDI‐II), well‐being (WHO‐5), functional disability (Sheehan Disability Scale), general psychological symptoms (SCL‐90‐R), and others. Results: In the depression trial, we found a statistically significant difference in depression symptoms between intervention groups at 18‐month follow‐up, in favor of collaborative care (4.4, 95%CI 2.8–7.0, p ≤ 0.001). Many other outcomes showed significant differences between groups, such as anxiety symptoms, functional level, well‐being, general psychological symptoms, and self‐efficacy. In the anxiety trial, we found no statistically significant difference between groups in anxiety symptoms (1.2, 95%CI −0.3–2.7, p ≤ 0.126). In this trial, significant differences between groups were found in outcomes measuring depression symptoms and general psychological symptoms but not in outcomes measuring functional level, well‐being or self‐efficacy. In both trials, no differences were found between groups on employment/education or sick leave measures. However, the collaborative care group in both trials had fewer contacts with private practicing psychologists during the 18 months follow‐up. Conclusion: At 18‐month follow‐up, we found a statistically significant difference between allocation groups, when measuring depression symptoms in the depression trial but not when measuring anxiety symptoms in the anxiety trial. Further, the collaborative care intervention may have the potential to reduce referrals to private practicing psychologists, a service that is in high demand in Denmark.

Community-based peer support complements regional mental health services by supporting individuals in their personal recovery process. This study aimed to investigate the effectiveness of the ‘Paths to everyday life’ (PEER) intervention, which adds group-based peer support to service as usual (SAU) for individuals with mental health difficulties, compared to SAU alone. A randomized controlled trial in five Danish municipalities compared the PEER intervention added to SAU to SAU alone. Participants were municipality social service users and self-referrals. The primary outcome was personal recovery, measured by Questionnaire about the Process of Recovery (QPR-15) at post-intervention. Intention-to-treat analyses were used for primary and safety outcomes. Of the 296 participants included from December 7, 2020, to October 16, 2022, 145 participants received the PEER intervention, and 151 participants received SAU alone. Primary outcome results showed model estimated marginals means in the PEER group [37.3; 95

Background In Denmark, 50% of those on long-term sick leave are affected by common mental disorders (CMDs), and it has been argued that detection in primary care has been insufficient. The Mental Health Assessment Study (MeHAS) assesses if specialized mental health assessments can enhance return to work for this group. This study aimed to estimate the effect of a specialized mental health assessment for people on sick leave with a mental health disorder, on return to work and mental health care utilization. Methods and findings In this experimental study, sickness absentees were referred from a sick leave benefit management agency. Before intervention allocation, they had already received a standard health assessment in general practice. The intervention group received an additional specialized mental health assessment, while the control group did not. We compared the groups on several vocational outcome measures, the primary being proportion in work after one year. Other outcomes were weeks in work, time to return to work (RTW) and different measures of service utilization. We included 717 in the intervention group and 756 in the control group. On the primary outcome, proportion in work, we observed no differences between the groups at 12 months (53.9% vs. 58.7% in the control group, p = 0.133). Moreover, after one year, the control group showed faster RTW at 12-month follow-up (HR 0.79, p<0.001) and 3.1 more weeks in work (p<0.001). In the intervention group, participants received more hospital-based outpatient mental healthcare. Conclusion Providing a specialized mental health assessment was associated with fewer weeks in work and longer sick leave duration (secondary outcomes), but the proportion in work at 12-month follow-up (primary outcome) did not differ between the groups. The intervention was associated with a higher likelihood of receiving specialized mental healthcare services, perhaps because more needs were met. Given the substantial risk of selection bias, results should be treated with caution.

This commentary highlights two cross-cultural issues identified from our global mental health (GMH) research, RECOLLECT (Recovery Colleges Characterisation and Testing) 2: self-enhancement and ingroup biases. Self-enhancement is a tendency to maintain and express unrealistically positive self-views. Ingroup biases are differences in one’s evaluation of others belonging to the same social group. These biases are discussed in the context of GMH research using self-report measures across cultures. GMH, a field evolving since its Lancet series introduction in 2007, aims to advance mental health equity and human rights. Despite a 16.5-fold increase in annual GMH studies from 2007 to 2016, cross-cultural understanding remains underdeveloped. We discuss the impact of individualism versus collectivism on self-enhancement and ingroup biases. GMH research using concepts, outcomes, and methods aligned with individualism may give advantages to people and services oriented to individualism. GMH research needs to address these biases arising from cross-cultural differences to achieve its aim.

BACKGROUND:Evidence of incidence of functional somatic disorders (FSD) is hampered by unclear delimitations of the conditions and little is known about the possible interchangeability between syndromes. Further, knowledge on remission and persistence of FSD in the general population is limited. We aimed to assess the natural course of various FSD over 5 years in the general population. METHODS:A follow-up study (Danish Study of Functional Disorders-DanFunD) was conducted in a random sample of the general population comprising 5,738 participants aged 18-76 years at baseline. Both at baseline and five-year follow-up, participants filled in validated questionnaires on symptoms to delimitate two approaches of FSD, the bodily distress syndrome (BDS) and four functional somatic syndromes (FSS): irritable bowel (IB), chronic fatigue (CF), chronic widespread pain (CWP), and multiple chemical sensitivity (MCS). RESULTS:Both BDS and FSS showed a five-year incidence around 11%. Incidence of the individual FSS varied from 0.8% (MCS) to 5.7% (CF). BDS and FSS showed a remission proportion close to 50%. We found a high degree of interchangeability between each FSS varying from 15.0% to 23.4%. CONCLUSION:We identified a marked fluctuation pattern of FSD during a five-year period, with a high degree of interchangeability between each FSS. The study stresses the importance of large population-based cohorts with transparent delimitation of FSD in future research to understand these complex conditions.

Despite the substantial disease burden of anxiety disorders, only limited or conflicting data on prognostic factors is available. Most studies include patients in the secondary healthcare sector thus, the generalizability of findings is limited. The present study examines predictors of symptom reduction and remission in patients with anxiety disorders in a primary care setting. 214 patients with anxiety disorders, recruited as part of the Collabri Flex trial, were included in secondary analyses. Data on potential predictors of anxiety symptoms at 6-month follow-up was collected at baseline, including patient characteristics related to demography, illness, comorbidity, functional level, life quality, and self-efficacy. The outcomes were symptom reduction and remission. Univariate and multivariate linear and logistic regression analyses were conducted to assess the associations between predictor variables and the outcome, and machine-learning methods were also applied. In multiple linear regression analysis, anxiety severity at baseline (β = -6.05, 95

Aims: To assess whether lifestyle factors, including sleep pattern, are predictors for the development of functional somatic disorder (FSD).Methods: A population-based prospective cohort of 9656 men and women aged 18-76 years was established in 2011-2015 and invited for re-examination in 2017-2020, when 5738 participated. Median follow-up period was 65 months. Participants filled in validated questionnaires on lifestyle, sleep pattern and various delimitations of FSD, which were operationalized using two different approaches: bodily distress syndrome (BDS) and functional somatic syndromes (FSS) (i.e. chronic fatigue, chronic widespread pain (CWP), irritable bowel, and multiple chemical sensitivity (MCS)). Baseline lifestyle and sleep pattern in relation to incidence of BDS and FSS (chronic fatigue, CWP, irritable bowel, MCS) was analysed by logistic regressions, adjusted for age, sex and subjective social status.Results: Inferior sleep quality at baseline predicted both incidence of BDS and all FSS delimitations except MCS. Smoking, alcohol intake, and low physical activity, but not diet, were predictors for the development of BDS. No uniform pattern was observed for the FSS. Smoking predicted development of chronic fatigue, CWP and irritable bowel, but not MCS. Alcohol and food quality only influenced the development of chronic fatigue whereas low physical activity only influenced the development of chronic fatigue and CWP.Conclusions: Lifestyle factors and sleep pattern seem to be predictors for some delimitations of FSD, but the importance of the various lifestyle factors is different for the different delimitations. The study shows the importance of analysing the various FSSs separately.

Objective Traumatic brain injuries (TBI), irrespective of severity, may have long-term social implications. This study explores the relationships between TBI severity and outcomes related to work stability, divorce, and academic achievement. Methods Using a Danish nationwide sample of persons with and without TBI, we employed case-control and longitudinal cohort designs. The case-control design utilized individuals aged 18 to 60 years and examined work stability. Each case, employed at time of TBI, was compared with 10 matched controls. The cohort design utilized individuals alive from 1980 to 2016 with and without TBI and assessed the likelihood of 1) divorce and 2) higher-level education. TBI exposures included concussion, skull fractures, or confirmed TBI. Results TBI cases exhibited higher odds ratios (OR) for work instability at all follow-ups compared to controls. Increased TBI severity was associated with a higher risk of work instability at 2-year follow-up (concussion: OR = 1.83; skull fracture: OR = 2.22; confirmed TBI: OR = 4.55), and with a higher risk of not working at 10-year follow-up (confirmed TBI: OR = 2.82; concussion: OR = 1.63). The divorce incidence rate ratio (IRR) was elevated in individuals with TBI (males: IRR = 1.52; females: IRR = 1.48) compared to those without TBI. Individuals with childhood TBI had reduced chances of attaining high school degree or higher (males: IRR = 0.79; females: IRR = 0.85) compared to those without TBI. Conclusion TBI is associated with an increased long-term risk of social consequences, including work instability, divorce, and diminished chances of higher education, even in cases with concussion.

Abstract Background Health institutions advocate for psychosocial and recovery-oriented interventions alongside pharmacological treatment for severe mental illness. Participatory arts interventions appear promising in promoting personal recovery by fostering connectedness, hope, renegotiation of identity, meaning-making, and empowerment. Despite encouraging findings, however, the evidence base remains thin. Further, results from cognitive literature studies suggest possible impact on parameters of clinical recovery, but this has not been studied in clinical contexts. We developed REWRITALIZE, a structured, recovery-oriented, fifteen-session creative writing group intervention led by a professional author alongside a mental health professional. Participants engage with literary forms, write on them, share their texts, and partake in reflective discussions within a supportive, non-stigmatising environment, designed to promote self-expression, playful experimentation, agency, recognition, participatory meaning-making, renegotiation of identity and social engagement. The aim of this project is to evaluate REWRITALIZE for persons with severe mental illness through a randomised controlled trial (RCT) focusing on personal recovery outcomes. Additionally, an embedded pilot RCT will explore additional outcomes i.e., clinical recovery for a subgroup with schizophrenia spectrum disorders. Methods The RCT is an investigator-initiated, randomised, two-arm, assessor-blinded, multi-center, waiting-list superiority trial involving 300 participants (age > 18) from six psychiatric centers in regions Capital and Zealand in Denmark, randomised to receive either the creative writing intervention combined with standard treatment or standard treatment alone. Assessments will be conducted before and after the intervention and at six months post intervention. The primary outcome is personal recovery at the end of intervention measured with the questionnaire of the process of recovery. Secondary outcomes include other measures of personal recovery, self-efficacy, mentalising, and quality of life. The pilot RCT, integrated within the RCT, will focus on 70 of the participants aged 18–35 with schizophrenia spectrum disorders, evaluating exploratory measures related to perspective-taking, social cognition, cognitive function, psychosocial functioning, and symptom pressure. Discussion This is the first RCT for creative writing groups. It assesses whether REWRITALIZE, as adjunct to standard mental healthcare, is more effective for personal recovery than standard care. If successful, it would provide evidence for the efficacy of REWRITALIZE, potentially enabling its implementation across mental health centers in Denmark.

BackgroundWorldwide, peers support has been shown to play a crucial role in supporting people with mental illness in their personal recovery process and return to everyday life. Qualitiative studies underpinning the mechanisms of change in peer support has been reviewed. However, the findings are primeraly based on the perspectives of peer support workers employed in mental health services. Thus, qualitiative studies elucidating the mechanisms of change from the recipient perspective in mental health service independent civil society settings are higly needed to further contribute to the evidence of peer support. The 'Paths to every day life' (PEER) is evaluated in a randomized trial and is substantiated by qualitative studies investigating the experiences of PEER from the perspectives of the recipients and the facilitators of peer support. The purpose of this qualitative study underpinned by critical realism was to substantiate the PEER intervention program theory by gaining deeper insight into the change mechanisms and elaborate how, when, and under what circumstances the peer support groups potentially had or did not have an impact on personal recovery from the perspectives of the recipients of peer support.MethodsEleven individuals were interviewed at the end of the ten-week group course. The semi-structured realist-inspired interviews were audio recorded and transcribed verbatim. The analysis was guided by reflective thematic analysis and through an abductive framework based on the program theory. Data were coded and analysed in Nvivo software.ResultsFour overarching themes were identified that informed and nuanced the program theory: 1) Connectedness as a prerequisite for engagement; 2) A sense of hope by working out new paths to recovery; 3) Seeing new sides of oneself; and 4) Sprout for change.ConclusionsThis study substantiates the program theory and the quantitative results of the PEER trial by elaborating on mechanisms that were felt to be essential for the personal recovery process from the perspectives of the recipients of the group-based peer support. In addition, the study points out that the opportunities to act in everyday life depended on individual context and where the group participants were on their recovery journey.Trial registrationClinicalTrials.gov identifier: NCT04639167.

Recovery Colleges (RCs) are learning-based mental health recovery communities, located globally. However, evidence on RC effectiveness outside Western, educated, industrialised, rich, and democratic (WEIRD) countries is limited. This study aimed to evaluate associations between cultural characteristics and RC fidelity, to understand how culture impacts RC operation. Service managers from 169 RCs spanning 28 WEIRD and non-WEIRD countries assessed the fidelity using the RECOLLECT Fidelity Measure, developed based upon key RC operation components. Hofstede's cultural dimension scores were entered as predictors in linear mixed-effects regression models, controlling for GDP spent on healthcare and Gini coefficient. Higher Individualism and Indulgence, and lower Uncertainty Avoidance were associated with higher fidelity, while Long-Term Orientation was a borderline negative predictor. RC operations were predominantly aligned with WEIRD cultures, highlighting the need to incorporate non-WEIRD cultural perspectives to enhance RCs' global impact. Findings can inform the refinement and evaluation of mental health recovery interventions worldwide.
