RESUMEN
Evidence shows that parenting interventions are an effective method of reducing caregiver-perpetrated child maltreatment. The recent COVID-19 pandemic has changed the provision of parenting interventions worldwide, with many interventions adapting to continue providing services during the crisis. This global systematic review examined how parenting interventions targeting child maltreatment and its risk and protective factors were adapted during the COVID-19 pandemic. We searched for studies published between 2020 and 2022 and identified 31 eligible studies. The data on the rationale, process, feasibility, acceptability, and impacts of adaptations were narratively synthesized in accordance with the Framework for Reporting Adaptations and Modifications to Evidence-Based Interventions. Results showed that most adaptations were proactive and focused on delivery methods, predominantly digitalization. While feasibility and acceptability were generally observed, the impacts of adapted programs were inconclusive. Inadequate reporting, especially regarding rationale, fidelity, facilitator capacity building, stakeholder involvement, and decision-making processes, was noted. The review recommends enhanced planning, documentation, and reporting of program adaptations using established guidelines, as well as process and impact evaluations.
RESUMEN
Health Pathfinder is a multilevel system change intervention initiated to transform the health response to domestic violence and abuse in eight sites in England. The current study drew upon interviews with health professionals (n = 27) and victim-survivors (n = 20) to provide a realist account of how this intervention achieved its goals. Findings show that five change mechanisms explain why Health Pathfinder was effective as an ecological intervention: awareness, expertise, relationships, empowerment, and evidence. Positive progress in respect of each mechanism had meaningful impacts on victim-survivor experiences of enquiry, disclosure, and uptake of services and had the potential to meaningfully impact health inequities.
RESUMEN
BACKGROUND: The Movethehip trial investigates the effectiveness of an exercise and patient education intervention for adults with acetabular dysplasia. The intervention involves eight tailored one-to-one sessions with trained providers who employ supportive feedback tools. The present protocol reports a planned process evaluation, which aims to determine how the intervention functions by examining the implementation of the intervention (process, dose and reach), its acceptability, mechanisms of change and the influence of contextual factors. METHODS: Two hundred trial participants aged 18-50 years will be recruited from a University Hospital in Denmark and randomised to the intervention or control group. Approximately ten providers will deliver the intervention. The process evaluation adopts a concurrent mixed-methods design. The implementation will be assessed using self-report questionnaires (at baseline and 6-month follow-up), training records and semi-structured focus group interviews with intervention providers (n = 10) and healthcare managers (n = 4-6). The mechanisms of change will be explored through semi-structured one-to-one interviews (at baseline and 6-month follow-up) with 15-20 purposefully sampled participants and by measuring changes in health outcomes (self-reported pain, physical functioning and quality of life completed at baseline and at 3- and 6-month follow-up). Additionally, change will be measured through an explorative examination of associations between dose and change in health outcomes, applying simple linear regression models. The acceptability of the intervention and the influence of contextual factors will be explored through one-to-one participant interviews and focus group interviews with 4-6 healthcare managers. The interviews will focus on expectations, experiences, events, personal understandings and interaction with interpersonal and organisational aspects. Interview data will be analysed using theoretical thematic analyses, and findings will be merged with quantitative data and reported jointly on a theme-by-theme basis. DISCUSSION: The process evaluation conducted as part of the MovetheHip trial will illuminate how the intervention functions, and if the intervention is proven effective, the findings of the evaluation will contribute to pinpoint how the intervention may be optimised to facilitate future up-scaling and implementation. TRIAL REGISTRATION: The MovetheHip protocol was approved by the Committee on Health Research Ethics in the Central Denmark Region. ClinicalTrials, NCT04795843. Registered on 20 March 2021.

Adaptation seeks to transfer and implement healthcare interventions developed and evaluated in one context to another. The aim of this scoping review was to understand current approaches to the adaptation of complex interventions for people with long-term conditions (LTCs) and to identify issues for studies performed in low- and middle-income countries (LMICs). Bibliographic databases were searched from 2000 to October 2022. This review involved five stages: (i) definition of the research question(s); (ii) identifying relevant studies; (iii) study selection; (iv) data charting; and (v) data synthesis. Extraction included an assessment of the: rationale for adaptation; stages and levels of adaptation; use of theoretical frameworks, and quality of reporting using a checklist based on the 2021 ADAPT guidance. Twenty-five studies were included from across 21 LTCs and a range of complex interventions. The majority (16 studies) focused on macro (national or international) level interventions. The rationale for adaptation included intervention transfer across geographical settings [high-income country (HIC) to LMIC: six studies, one HIC to another: eight studies, one LMIC to another: two studies], or transfer across socio-economic/racial groups (five studies), or transfer between different health settings within a single country (one study). Overall, studies were judged to be of moderate reporting quality (median score 23, maximum 46), and typically focused on early stages of adaptation (identification and development) with limited outcome evaluation or implementation assessment of the adapted version of the intervention. Improved reporting of the adaptation for complex interventions targeted at LTCs is needed. Development of future adaptation methods guidance needs to consider the needs and priorities of the LMIC context.
Limited finance and human capacity may reduce access to new treatments for people with long-term conditions. This is especially true in low- and middle-income countries. One solution is to transfer treatments developed in one place for use in other areas. This paper provides a current summary of international research on adapting treatments. We used a checklist to assess study reporting quality, based on published advice. Our findings showed the need for better conduct and reporting of adaptation. Future guidance should consider the specific needs of low- and middle-income countries.
RESUMEN
BACKGROUND: Family group conferences (FGCs) in child welfare bring immediate and wider family members together to decide on the best way to meet a child's needs. Unlike professionally led meetings, the aim is for decisions to be made by or with family members. Qualitative and mixed-method research with FGC participants tends to show positive experiences: most participants feel their voices are heard; FGCs facilitate family-driven solutions and closer relationships-within families and with social workers. Although there is existing literature on FGCs, there is a paucity of robust comparative UK evaluations, i.e., randomised controlled trials or quasi-experimental studies. Comparative studies internationally have focused on a narrow range of outcomes, not recognised the importance of context, and paid little attention to the quality of delivery. Some qualitative studies have considered process and context but there is scant measurement of these. The aims of this study are, firstly, to establish how FGCs improve outcomes for families and what factors vary their quality, and, secondly, to assess longer-term outcomes in terms of service use and associated costs. METHODS: Given the importance of process and context, evaluation informed by realist and complex systems approaches is needed. This multi-method evaluation includes a survey of FGC services in all UK local authorities (n = 212) to map service provision; co-design of programme theory and evaluation measures with family members who have experienced an FGC (n = 16-24) and practitioners (n = 16-24) in two sites; a prospective single-arm study of FGC variability and outcomes after six months; and comparison of service use and costs in FGC participants (n≥300 families) and a control group (n≥1000) after two years using a quasi-experiment. DISCUSSION: This is a pragmatic evaluation of an existing intervention, to identify what mechanisms and contexts influence effective process and longer-term outcomes. The study is registered with Research Registry (ref. 7432).

Introduction: Adolescence is a critical time for mental health promotion and prevention and establishing healthy behaviours. Implementing universal, school-based psychosocial interventions can improve short- and long-term health trajectories for adolescents. While these interventions may offer important opportunities for fostering skills and relationships, few school-based interventions have been developed for and tested in low- and middle-income countries (LMICs) where adolescent mental health needs may be significant and under-served. This manuscript details the development of a multi-component, universal school-based intervention, Health Action in ScHools for a Thriving Adolescent Generation (HASHTAG), for adolescents aged 12-15 years in Nepal and South Africa. Methods and results: We describe HASHTAG's development over four phases, combining methods and results as each phase was iteratively conducted between 2018 and 2021. Phase 1 included a systematic review and components analysis, building from WHO guidelines for adolescent mental health. Seven components were strongly supported by the evidence: emotional regulation, stress management, mindfulness, problem-solving, interpersonal skills, assertiveness training, and alcohol and drug education. Phase 2 encompassed site selection, theory of change development, and formative research engagements; research teams in each site engaged adolescents and key adult stakeholders to identify priorities for intervention. Stakeholders voiced preferences for external facilitators and key content and delivery for intervention sessions. These findings informed Phase 3, a draft manual of HASHTAG, including a whole-school component, called Thriving Environment in Schools, and a classroom-based, six-session component, Thrive Together. In Phase 4, participants engaged in consultative workshops to review and contextualise content by country, preparing HASHTAG for implementation in a feasibility trial. Minor adaptations were made in Nepal, including using school nurses and adjusting take-home materials; both country's workshops identified practical considerations for implementing activities. Conclusions: HASHTAG was designed around core evidence-based components to increase translatability across LMICs, while enabling country-specific tailoring to enhance feasibility. Future research will test whether this multi-component, whole-school approach can improve adolescent mental health.
RESUMEN
Hydrogenases catalyze hydrogen/proton interconversion that is normally electrochemically reversible (having minimal overpotential requirement), a special property otherwise almost exclusive to platinum metals. The mechanism of [NiFe]-hydrogenases includes a long-range proton-coupled electron-transfer process involving a specific Ni-coordinated cysteine and the carboxylate of a nearby glutamate. A variant in which this cysteine has been exchanged for selenocysteine displays two distinct changes in electrocatalytic properties, as determined by protein film voltammetry. First, proton reduction, even in the presence of H2 (a strong product inhibitor), is greatly enhanced relative to H2 oxidation: this result parallels a characteristic of natural [NiFeSe]-hydrogenases which are superior H2 production catalysts. Second, an inflection (an S-shaped "twist" in the trace) appears around the formal potential, the small overpotentials introduced in each direction (oxidation and reduction) signaling a departure from electrocatalytic reversibility. Concerted proton-electron transfer offers a lower energy pathway compared to stepwise transfers. Given the much lower proton affinity of Se compared to that of S, the inflection provides compelling evidence that concerted proton-electron transfer is important in determining why [NiFe]-hydrogenases are reversible electrocatalysts.

Adults often experience a loss of social relations and sense of belonging in later life, leading to the risk of social isolation. Municipal senior centres offer a potential site for intervention, as they provide social communities targeting older people. However, not all older people find it easy to access these social communities due to experiencing physical and/or psychosocial frailties and could therefore continue to experience a decline in social relations and sense of belonging, which potentiates poor physical and psychosocial health and well-being. To date, there are limited evidence-based interventions in Denmark. The present article describes the development of an intervention to increase belongingness and decrease social isolation among older people with frailties who attend Danish municipal senior centres. The development process was conducted with reference to the INDEX (IdentifyiNg and assessing different approaches to DEveloping compleX intervention) guidance. The development process resulted in a 6-month supportive intervention, consisting of four elements: skills development workshops for all staff members; a start conversation including frailty screening; allocation of a 'buddy' among existing service users; and monthly follow-up conversations with staff members. This theory-informed approach can progress to feasibility testing and outcome evaluation in order to generate an evidence base. Concurrently, the article reflects on current guidance for intervention development and how it may be used and optimized to strengthen developmental processes in the future.

Youth in out-of-home care are at high risk for suicide-related thoughts and behaviors (STB), yet there are no known efficacious interventions that reduce STB for this population. Fostering Healthy Futures for Preteens (FHF-P) is a 9-month community-based mentoring and skills training preventive intervention for children in out-of-home care. A randomized controlled trial enrolled 156 participants aged 9-11 years who were placed in out-of-home care over the prior year. Participants were 48.9% female, 54.1% Hispanic, 30.1% Black, and 27.1% American Indian. Follow-up interviews, conducted 7-12 years postintervention (85.2% retention rate), asked young adult participants, aged 18-22, to self-report lifetime STB as indexed by non-suicidal self-injury, suicidal thoughts, plans, and/or attempts. There was a nonsignificant reduction in the odds of STB for the intervention group at follow-up (OR = 0.74; CI, 0.32, 1.69). However, FHF-P significantly moderated the effect of baseline STB; control youth who reported baseline STB had 10 times the odds of young adult STB (OR = 10.44, CI, 2.28, 47.78), but there was no increase in the odds of adult-reported STB for intervention youth. Findings suggest that FHF-P buffers the impact of pre-existing STB on young adult STB for care-experienced youth. Further research is needed to identify mechanisms that may reduce STB in this population.
RESUMEN
The mental health and wellbeing of children and young people who have been in care, primarily foster care, kinship care or residential care, remains a public health priority. The Care-experienced cHildren and young people's Interventions to improve Mental health and wEll-being outcomes Systematic review (CHIMES) synthesized evidence for the effectiveness of interventions targeting: subjective wellbeing; mental, behavioral and neurodevelopmental disorders; and suicide-related outcomes. Searches were conducted in 16 bibliographic databases and 22 websites between 1990 and 2022. This was supplemented by citation tracking, screening of relevant systematic reviews, and expert recommendation. We identified 35 interventions, with 44 evaluations via randomized controlled trials. Through meta-analyses, we found that interventions have a small beneficial impact on a variety of mental health outcomes in the short term (0-6 months). Interventions improved total social, emotional, and behavioral problems (d = -0.15, 95% CI [-0.28, -0.02]), social-emotional functioning difficulties (d = -0.18, 95% CI [-0.31, -0.05]), externalizing problem behaviors (d = -0.30, 95% CI [-0.53, -0.08]), internalizing problem behaviors (d = -0.35, 95% CI [-0.61, -0.08]); and depression and anxiety (d = -0.26, 95% CI [-0.40, -0.13]). Interventions did not demonstrate any effectiveness for outcomes assessed in the longer term (>6 months). Certainty of effectiveness was limited by risk of bias and imprecision. There was limited available evidence for interventions targeting subjective wellbeing and suicide-related outcomes. Future intervention design and delivery must ensure that programs are sufficient to activate causal mechanisms and facilitate change. Evaluation research should use a robust methodology.PROSPERO Registration: CRD42020177478.
RESUMEN
BACKGROUND: Campylobacter jejuni and Campylobacter coli are the major causative agents of bacterial gastroenteritis worldwide and are known obligate microaerophiles. Despite being sensitive to oxygen and its reduction products, both species are readily isolated from animal food products kept under atmospheric conditions where they face high oxygen tension levels. RESULTS: In this study, Transposon Directed Insertion-site Sequencing (TraDIS) was used to investigate the ability of one C. jejuni strain and two C. coli strains to overcome oxidative stress, using H2O2 to mimic oxidative stress. Genes were identified that were required for oxidative stress resistance for each individual strain but also allowed a comparison across the three strains. Mutations in the perR and ahpC genes were found to increase Campylobacter tolerance to H2O2. The roles of these proteins in oxidative stress were previously known in C. jejuni, but this data indicates that they most likely play a similar role in C. coli. Mutation of czcD decreased Campylobacter tolerance to H2O2. The role of CzcD, which functions as a zinc exporter, has not previously been linked to oxidative stress. The TraDIS data was confirmed using defined deletions of perR and czcD in C. coli 15-537360. CONCLUSIONS: This is the first study to investigate gene fitness in both C. jejuni and C. coli under oxidative stress conditions and highlights both similar roles for certain genes for both species and highlights other genes that have a role under oxidative stress.

INTRODUCTION: Family-Focused Adolescent & Lifelong Health Promotion (FLOURISH) project will adapt, implement and evaluate a programme to support adolescent mental health and well-being through strategies, such as strengthening parenting practices, adolescent-caregiver relationships, adolescent and parent socioemotional skills, and social support. METHODS AND ANALYSIS: The project will focus on adolescents aged 10-14 years and their caregivers in North Macedonia and Moldova. The countries were selected based on implementation readiness of two organisations and a need for accessible evidence-informed services to help mitigate health risks due to economic, social and political challenges. Parenting for Lifelong Health (PLH) for Parents and Teens is a family-based programme developed for low-resource settings. PLH has been adapted with input from advisory groups. The programme includes additional components to strengthen impacts on adolescents: adolescent mental health tools, based on UNICEF's Helping Adolescents Thrive, adolescent peer support and participation booster. This pilot is first of three study phases. The pilot will be a feasibility testing of the adapted intervention and the assessment and implementation procedures to determine further refinements. The pilot will examine if the adapted programme is acceptable for adolescents, their families and providers, explore contextual factors relevant to embedding this programme into longer-term scale-up and investigate whether the programme can be delivered with fidelity and participation; whether the participants report changes in adolescent emotional and behavioural problems, well-being and other outcomes; and whether the study tools are feasible and appropriate. Pre-post adolescent and caregiver questionnaires will provide outcome data. Process evaluation will include attendance and fidelity data, and focus groups. We will examine delivery cost and resource requirements. ETHICS AND DISSEMINATION: The study was approved at the University of Klagenfurt (Austria), Medical Faculty at St. Cyril and Methodius University (North Macedonia) and National Committee of Ethical Expertise for Clinical Trials (Moldova). Through stakeholder engagement and dissemination, FLOURISH will advance scale-up of open-source family interventions.

Existing frameworks for developing public health interventions have limited guidance for researchers on how to work with stakeholders to co-produce context-specific interventions. To address this, a promising framework for the co-production of public health interventions was developed through a previous review of school-based co-production. The present study aimed to optimise this co-production framework through applying and testing it in real-world secondary school contexts. Within schools, Research Action Groups (RAGs) were established with multiple school stakeholders supported by an external facilitator to use school data to produce school-specific mental health and wellbeing interventions. A mixed method process evaluation of two contextually diverse case study secondary schools in the UK was used to optimise the co-production framework. The process evaluation sought the views of those involved (students, school staff, school Senior Management Team (SMT) members, and the external co-production facilitator/researcher) on the co-production functions they were involved in so they could be modified, if needed. Data collected for the process evaluation during co-production were a researcher diary (n = 45 entries), and observations of student photography (n = 21) and RAG meetings (n = 8). Post co-production, interviews, and surveys with RAG students (n = 18) and staff (n = 8), and two school-specific SMT focus groups (n = 10) were conducted. The study identified four recommendations to optimise and integrate co-production into real world practice. They include the need to: assess schools for their readiness to undertake co-production; more effectively communicate the necessity to have stakeholders from the whole system involved; work with SMTs throughout co-production functions; involve stakeholders outside the school to support producing solutions to change school mental health and wellbeing priorities. The framework is intended to be used by researchers to integrate stakeholders into a shared decision-making process to develop interventions that meet the needs and contexts of individual schools. It could be transferred to other settings to support the development of public health interventions for other health areas, and populations. Further evaluation to test its use in other settings is needed.

This paper draws on a qualitative interview-based study that explored online mental health and wellbeing interventions and services for care-experienced young people. The study involved young people (n = 4), foster carers (n = 8), kinship carers (n = 2) and social care professionals (n = 9) in Wales, UK. The paper reflects on the complexities of online communication in the space of 'the home'. It documents the ways in which care-experienced young people's living arrangements can restrict access to services and complicate confidentiality within portals to the virtual world, creating an environment where young people and their carers 'wouldn't want to talk about anything too personal'. Drawing on data generated in a study focused on services and interventions to support the mental health and wellbeing of care-experienced children and young people, the paper considers privacy, confidentiality and surveillance in the home and reflects on how associated relational practices impact on care-experienced young people. While the data discussed in this paper was generated during the Covid-19 pandemic, its findings have implications for how care-experienced young people and their carers can be supported to engage with the digital world in the future.
When mental health services are delivered online, they are usually accessed from home. Home can be different for young people who grow up in care, with records kept about their day-to-day activities, a lack of access to the digital world and policy governing how they are able to live their lives. We spoke with young people, foster carers and practitioners about what it is like for young people to access mental health services online. The paper discusses how the private home lives of care-experienced children and young people impacts on how they are able to access much needed mental health services. We look at the need to protect the freedom of children in care and care-experienced young people to take risks and access digital spaces like other children and teenagers do, while also recognising the reality of the pressures on practitioners and carers to protect looked after children from harm.
RESUMEN
The membrane-bound [NiFe]-hydrogenase of Cupriavidus necator is a rare example of a truly O2-tolerant hydrogenase. It catalyzes the oxidation of H2 into 2e- and 2H+ in the presence of high O2 concentrations. This characteristic trait is intimately linked to the unique Cys6[4Fe-3S] cluster located in the proximal position to the catalytic center and coordinated by six cysteine residues. Two of these cysteines play an essential role in redox-dependent cluster plasticity, which bestows the cofactor with the capacity to mediate two redox transitions at physiological potentials. Here, we investigated the individual roles of the two additional cysteines by replacing them individually as well as simultaneously with glycine. The crystal structures of the corresponding MBH variants revealed the presence of Cys5[4Fe-4S] or Cys4[4Fe-4S] clusters of different architecture. The protein X-ray crystallography results were correlated with accompanying biochemical, spectroscopic and electrochemical data. The exchanges resulted in a diminished O2 tolerance of all MBH variants, which was attributed to the fact that the modified proximal clusters mediated only one redox transition. The previously proposed O2 protection mechanism that detoxifies O2 to H2O using four protons and four electrons supplied by the cofactor infrastructure, is extended by our results, which suggest efficient shutdown of enzyme function by formation of a hydroxy ligand in the active site that protects the enzyme from O2 binding under electron-deficient conditions.
RESUMEN
While the importance of mental health and its impact on overall health and well-being has been widely recognized, there continue to be ongoing barriers to accessing mental health services. This is particularly poignant in countries in Southeast Asia (SEA) where there may be further stigma in accessing mental health services. As no reviews have been undertaken on this topic, this review aims to outline the barriers and enablers to access and utilization of mental health care services in SEA. Searches were undertaken in commercially produced and gray literature sources. Two independent reviewers screened the results. The data were then independently extracted, which was then collated and synthesized, using the Health Belief Model (HMB) as a framework. Twelve studies were included in the review. Under the HBM, barriers were grouped into: stigma, poor health literacy, internalized reasons, cultural beliefs, lack of training of health professionals, quality of service, and poor distribution of resources. Enablers included: social support, outreach services, structural stigma, self-awareness, resources and information, accessibility and affordability, and positive attitudes and beliefs about health professionals. Those accessing mental health care in SEA are confronted by complex barriers and few enablers. Ongoing stigma and a distinct lack of resources pose the greatest challenges, which are even more amplified for those in rural areas and minority groups. A multifaceted strategy that improves the structures, processes, and outcomes of mental health is required within these communities.

The active site of [NiFe]-hydrogenases contains a strictly-conserved pendant arginine, the guanidine head group of which is suspended immediately above the Ni and Fe atoms. Replacement of this arginine (R479) in hydrogenase-2 from E. coli results in an enzyme that is isolated with a very tightly-bound diatomic ligand attached end-on to the Ni and stabilised by hydrogen bonding to the Nζ atom of the pendant lysine and one of the three additional water molecules located in the active site of the variant. The diatomic ligand is bound under oxidising conditions and is removed only after a prolonged period of reduction with H2 and reduced methyl viologen. Once freed of the diatomic ligand, the R479K variant catalyses both H2 oxidation and evolution but with greatly decreased rates compared to the native enzyme. Key kinetic characteristics are revealed by protein film electrochemistry: most importantly, a very low activation energy for H2 oxidation that is not linked to an increased H/D isotope effect. Native electrocatalytic reversibility is retained. The results show that the sluggish kinetics observed for the lysine variant arise most obviously because the advantage of a more favourable low-energy pathway is massively offset by an extremely unfavourable activation entropy. Extensive efforts to establish the identity of the diatomic ligand, the tight binding of which is an unexpected further consequence of replacing the pendant arginine, prove inconclusive.

BACKGROUND: The mental health and wellbeing of care-experienced children and young people (i.e. foster care, kinship care, residential care) is poorer than non-care-experienced populations. The Care-experienced cHildren and young people's Interventions to improve Mental health and wEll-being outcomes Systematic review (CHIMES) aimed to synthesise the international evidence base for interventions targeting subjective wellbeing, mental health and suicide amongst care-experienced young people aged ≤ 25 years. METHODS: For the first phase of the review, we constructed an evidence map identifying key clusters and gaps in interventions and evaluations. Studies were identified through 16 electronic databases and 22 health and social care websites, in addition to expert recommendations, citation tracking and screening of relevant systematic reviews. We charted interventions and evaluations with a summary narrative, tables and infographics. RESULTS: In total, 64 interventions with 124 associated study reports were eligible. The majority of study reports were from the USA (n = 77). Interventions primarily targeted children and young people's skills and competencies (n = 9 interventions), the parental functioning and practices of carers (n = 26), or a combination of the two (n = 15). While theoretically under-specified, interventions were largely informed by theories of Attachment, Positive Youth Development, and Social Learning Theory. Current evaluations prioritised outcomes (n = 86) and processes (n = 50), with a paucity of study reports including theoretical descriptions (n = 24) or economic evaluations (n = 1). Interventions most frequently targeted outcomes related to mental, behavioural or neurodevelopmental disorders, notably total social, emotional and behavioural problems (n = 48 interventions) and externalising problem behaviours (n = 26). There were a limited number of interventions targeting subjective wellbeing or suicide-related outcomes. CONCLUSIONS: Future intervention development might focus on structural-level intervention theories and components, and target outcomes related to subjective wellbeing and suicide. In accordance with current methodological guidance for intervention development and evaluation, research needs to integrate theoretical, outcome, process and economic evaluation in order to strengthen the evidence base.
