Background Peer support for mental health is recommended across international policy guidance and provision. Our systematic umbrella review summarises evidence on the effectiveness, implementation, and experiences of paid peer support approaches for mental health. Methods We searched MEDLINE, EMBASE, PsycINFO, The Campbell Collaboration, and The Cochrane Database of Systematic Reviews (2012–2022) for reviews of paid peer support interventions for mental health. The AMSTAR2 assessed quality. Results were synthesised narratively, with implementation reported using the CFIR (Consolidated Framework for Implementation Research). The protocol was registered with PROSPERO (registration number: CRD42022362099). Results We included 35 reviews (426 primary studies, n  = 95–40,927 participants): systematic reviews with ( n  = 13) or without ( n  = 13) meta-analysis, or with qualitative synthesis ( n  = 3), scoping reviews ( n  = 6). Most reviews were low or critically low (97%) quality, one review was high quality. Effectiveness was investigated in 23 reviews. Results were mixed; there was some evidence from meta-analyses that peer support may improve depression symptoms (particularly perinatal depression), self-efficacy, and recovery. Factors promoting successful implementation, investigated in 9 reviews, included adequate training and supervision, a recovery-oriented workplace, strong leadership, and a supportive and trusting workplace culture with effective collaboration. Barriers included lack of time, resources and funding, and lack of recognised peer support worker (PSW) certification. Experiences of peer support were explored in 11 reviews, with 3 overarching themes: (i) what the PSW role can bring, including recovery and improved wellbeing for service users and PSWs; (ii) confusion over the PSW role, including role ambiguity and unclear boundaries; and (iii) organisational challenges and impact, including low pay, negative non-peer staff attitudes, and lack of support and training. Conclusions Peer support may be effective at improving some clinical outcomes, self-efficacy, and recovery. Certain populations, e.g. perinatal populations, may especially benefit from peer support. Potential strategies to successfully implement PSWs include co-production, clearly defined PSW roles, a receptive hierarchical structure and staff, appropriate PSW and staff training with clinical and/or peer supervision alongside safeguarding. Services could benefit from clear, coproduced, setting specific implementation guidelines for PSW. PSW roles tend to be poorly defined and associations between PSW intervention content and impacts need further investigation. Future research should reflect the priorities of providers/service users involved in peer support.

PurposeThe COVID-19 pandemic has many potential impacts on people with mental health conditions and on mental health care, including direct consequences of infection, effects of infection control measures and subsequent societal changes. We aimed to map early impacts of the pandemic on people with pre-existing mental health conditions and services they use, and to identify individual and service-level strategies adopted to manage these.MethodsWe searched for relevant material in the public domain published before 30 April 2020, including papers in scientific and professional journals, published first person accounts, media articles, and publications by governments, charities and professional associations. Search languages were English, French, German, Italian, Spanish, and Mandarin Chinese. Relevant content was retrieved and summarised via a rapid qualitative framework synthesis approach.ResultsWe found 872 eligible sources from 28 countries. Most documented observations and experiences rather than reporting research data. We found many reports of deteriorations in symptoms, and of impacts of loneliness and social isolation and of lack of access to services and resources, but sometimes also of resilience, effective self-management and peer support. Immediate service challenges related to controlling infection, especially in inpatient and residential settings, and establishing remote working, especially in the community. We summarise reports of swiftly implemented adaptations and innovations, but also of pressing ethical challenges and concerns for the future.ConclusionOur analysis captures the range of stakeholder perspectives and experiences publicly reported in the early stages of the COVID-19 pandemic in several countries. We identify potential foci for service planning and research.

PurposeResearch is beginning to quantify the impact of COVID-19 on people with pre-existing mental health conditions. Our paper addresses a lack of in-depth qualitative research exploring their experiences and perceptions of how life has changed at this time.MethodsWe used qualitative interviews (N = 49) to explore experiences of the pandemic for people with pre-existing mental health conditions. In a participatory, coproduced approach, researchers with lived experiences of mental health conditions conducted interviews and analysed data as part of a multi-disciplinary research team.ResultsExisting mental health difficulties were exacerbated for many people. People experienced specific psychological impacts of the pandemic, struggles with social connectedness, and inadequate access to mental health services, while some found new ways to cope and connect to the community. New remote ways to access mental health care, including digital solutions, provided continuity of care for some but presented substantial barriers for others. People from black and ethnic minority (BAME) communities experienced heightened anxiety, stigma and racism associated with the pandemic, further impacting their mental health.ConclusionThere is a need for evidence-based solutions to achieve accessible and effective mental health care in response to the pandemic, especially remote approaches to care. Further research should explore the long-term impacts of COVID-19 on people with pre-existing mental health conditions. Particular attention should be paid to understanding inequalities of impact on mental health, especially for people from BAME communities.

Background Loneliness and social isolation are increasingly recognised as prevalent among people with mental health problems, and as potential targets for interventions to improve quality of life and outcomes, as well as for preventive strategies. Understanding the relationship between quality and quantity of social relationships and a range of mental health conditions is a helpful step towards development of such interventions. Purpose Our aim was to give an overview of associations between constructs related to social relationships (including loneliness and social isolation) and diagnosed mental conditions and mental health symptoms, as reported in systematic reviews of observational studies. Methods For this umbrella review (systematic review of systematic reviews) we searched five databases (PsycINFO, MEDLINE, EMBASE, CINAHL, Web of Science) and relevant online resources (PROSPERO, Campbell Collaboration, Joanna Briggs Institute Evidence Synthesis Journal). We included systematic reviews of studies of associations between constructs related to social relationships and mental health diagnoses or psychiatric symptom severity, in clinical or general population samples. We also included reviews of general population studies investigating the relationship between loneliness and risk of onset of mental health problems. Results We identified 53 relevant systematic reviews, including them in a narrative synthesis. We found evidence regarding associations between (i) loneliness, social isolation, social support, social network size and composition, and individual-level social capital and (ii) diagnoses of mental health conditions and severity of various mental health symptoms. Depression (including post-natal) and psychosis were most often reported on, with few systematic reviews on eating disorders or post-traumatic stress disorder (PTSD), and only four related to anxiety. Social support was the most commonly included social construct. Our findings were limited by low quality of reviews and their inclusion of mainly cross-sectional evidence. Conclusion Good quality evidence is needed on a wider range of social constructs, on conditions other than depression, and on longitudinal relationships between social constructs and mental health symptoms and conditions.

Loneliness is associated with many mental health conditions, as both a potential causal and an exacerbating factor. Richer evidence about how people with mental health problems experience loneliness, and about what makes it more or less severe, is needed to underpin research on strategies to help address loneliness. Our aim was to explore experiences of loneliness, as well as what helps address it, among a diverse sample of adults living with mental health problems in the UK. We recruited purposively via online networks and community organisations, with most interviews conducted during the COVID-19 pandemic. Qualitative semi-structured interviews were conducted with 59 consenting participants face-to-face, by video call or telephone. Researchers with relevant lived experience were involved at all stages, including design, data collection, analysis and writing up of results. Analysis led to identification of four overarching themes: 1. What the word \"lonely\" meant to participants, 2. Connections between loneliness and mental health, 3. Contributory factors to continuing loneliness, 4. Ways of reducing loneliness. Central aspects of loneliness were lack of meaningful connections with others and lack of a sense of belonging to valued groups and communities. Some drivers of loneliness, such as losses and transitions, were universal, but specific links were also made between living with mental health problems and being lonely. These included direct effects of mental health symptoms, the need to withdraw to cope with mental health problems, and impacts of stigma and poverty. The multiplicity of contributors to loneliness that we identified, and of potential strategies for reducing it, suggest that a variety of approaches are relevant to reducing loneliness among people with mental health problems, including peer support and supported self-help, psychological and social interventions, and strategies to facilitate change at community and societal levels. The views and experiences of adults living with mental health problems are a rich source for understanding why loneliness is frequent in this context and what may address it. Co-produced approaches to developing and testing approaches to loneliness interventions can draw on this experiential knowledge.

Loneliness is common among people with mental health problems and predicts poorer recovery from depression and anxiety. Needs for support with loneliness and social relationships are often under-addressed in mental health services. The Community Navigator programme was designed to reduce loneliness for adults (aged 18 and above) with complex depression or anxiety who were using secondary mental health services. Acceptability and feasibility of the programme and a trial evaluation were tested in a feasibility randomised controlled trial with qualitative evaluation. Forty participants with depression or anxiety using secondary mental health services were recruited from mental health services in two London sites and randomised to receive: the Community Navigator programme over six months in addition to routine care (n = 30); or routine care (n = 10). Measures of loneliness, depression, other clinical and social outcomes and service use were collected at baseline and six-months follow-up. Levels of engagement in the programme and rates of trial recruitment and retention were assessed. Programme delivery was assessed through session logs completed by Community Navigators. The acceptability of the programme was explored through qualitative interviews (n = 32) with intervention group participants, their family and friends, programme providers and other involved staff. Forty participants were recruited in four months from 65 eligible potential participants asked. No one withdrew from the trial. Follow-up interviews were completed with 35 participants (88%). Process records indicated the programme was delivered as intended: there was a median of seven meetings with their Community Navigator (of a maximum ten) per treatment group participant. Qualitative interviews indicated good acceptability of the programme to stakeholders, and potential utility in reducing loneliness and depression and anxiety. A definitive, multi-site randomised controlled trial is recommended to evaluate the effectiveness and cost-effectiveness of the Community Navigator programme for people with complex anxiety and depression in secondary mental health services.

Background #KindnessByPost (KbP) is a participatory public health initiative in which people anonymously send and receive cards containing messages of goodwill with others also taking part in the programme. Quantitative evaluations of KbP consistently find evidence of improvements to people’s mental wellbeing and feelings of loneliness after participation and three months later. Our aim in the present study is to develop a programme theory of KbP, which describes for whom the KbP intervention improves mental wellbeing, other reported impacts, in which contexts it has these effects, and the mechanisms by which it works. Methods We use a realist interviewing methodology to develop the programme theory. We conducted a focus group with the KbP executive team, and 20 one-to-one interviews with KbP participants. During analysis, a co-production working group iteratively developed a Theory of Change model comprising context-mechanism-outcome statements [CMOs] to map out the mechanisms present in KbP. Results We developed 145 CMO statements, which we condensed and categorized into 32 overarching CMOs across nine thematic topics: access to scheme; pathways to involvement; resources; culture; giving post; receiving post; content of received post; community; long term impact. These CMOs set out pathways through which KbP benefited participants, including from doing something kind for someone else, of receiving post and appreciating the effort that went into it, and from the creative process of creating post and writing the messages inside them. Effects were sustained in part through people keeping the cards and through the social media communities that emerged around KbP. Discussion Both giving and receiving post and the sense of community benefited participants and improved their mood and feelings of connectedness with others. Connection with a stranger, rather than friends or family, was also an important feature of the initiative for participants. Our wide range of CMO pathways by which KbP produced positive outcomes may mean that the intervention is applicable or adaptable across many communities and settings. Taken together with evidence from the quantitative evaluations, KbP is potentially an effective, low-cost, and highly scalable public health intervention for reducing loneliness and improving wellbeing.

Background Peer support roles within mental health services are rapidly increasing in number and scope in the UK and internationally. This paper explores the facilitators and barriers to delivering peer support effectively, as experienced by Peer Support Workers (PSWs) in a range of services and settings. Methods We conducted semi-structured qualitative interviews with paid mental health PSWs working across a range of settings in England. We took a collaborative, participatory approach. Interviews were carried out by researchers with experience of living with and/or supporting others with mental health conditions, and for some having experience delivering peer support themselves, and data were analysed using methods guided by general principles of thematic analysis. Results We interviewed 35 PSWs with a range of roles that spanned a range of mental health areas, and regions. Overarching facilitators and barriers were identified including the need for roles to have flexibility with some structure and boundaries; the need for support, supervision and training to ensure PSWs are skilled in delivering the unique elements of their job; the importance of working with a strong team and leaders who support and value PSW; the complexity of working where there are tensions between the flexibility of PSW and the structures of existing healthcare systems, as well as the systemic factors such as funding, pay and progression can have an effect both on the personal experience of PSWs and on the value placed on PSWs in the wider organisation. Conclusion Our findings highlight the complexity of peer support work and PSW roles, with a variety both of facilitators allowing them to carry out roles effectively and the barriers to doing so. As PSWs numbers and the scope of their roles increase, awareness of barriers and facilitators needs to inform PSW job roles, support systems and integration into teams and systems.

PurposeWe sought to understand how the experiences of people in the UK with pre-existing mental health conditions had developed during the course of the COVID-19 pandemic.MethodsIn September–October 2020, we interviewed adults with mental health conditions pre-dating the pandemic, whom we had previously interviewed 3 months earlier. Participants had been recruited through online advertising and voluntary sector community organisations. Semi-structured qualitative interviews were conducted by telephone or video-conference by researchers with lived experience of mental health difficulties, and, following principles of thematic analysis, were analysed to explore changes over time in people’s experience of the pandemic.ResultsWe interviewed 44 people, achieving diversity of demographic characteristics (73% female, 54% White British, aged 18–75) and a range of mental health conditions and service use among our sample. Three overarching themes were derived from interviews. The first theme “spectrum of adaptation” describes how participants reacted to reduced access to formal and informal support through personal coping responses or seeking new sources of help, with varying degrees of success. The second theme describes “accumulating pressures” from pandemic-related anxieties and sustained disruption to social contact and support, and to mental health treatment. The third theme “feeling overlooked” reflects participants’ feeling of people with mental health conditions being ignored during the pandemic by policy-makers at all levels, which was compounded for people from ethnic minority communities or with physical health problems.ConclusionIn line with previous research, our study highlights the need to support marginalised groups who are at risk of increased inequalities, and to maintain crucial mental and physical healthcare and social care for people with existing mental health conditions, notwithstanding challenges of the pandemic.

Background Peer support roles in mental health services are significantly increasing in the United Kingdom and internationally. However, there is wide variation in these roles and limited research exploring the ways in which Peer Support Workers (PSWs) are currently working. We aimed to explore: 1) the values underpinning the PSW role; 2) the distinctive features of the work that PSWs’ do; and 3) the perceived impact of the PSW role. Methods We conducted semi-structured qualitative interviews with paid mental health PSWs working across a range of settings. We took a co-produced, participatory approach: interviews were carried out by researchers with lived experience of mental health conditions and data were analysed using collaborative methods, guided by general principles of thematic analysis. Results We interviewed 35 PSWs. Overarching themes identified from iterative analysis included: 1) Underpinning values: (i) Recovery is possible: fostering hope, role-modelling and encouraging change, (ii) Mutuality: sharing lived experiences to bring empathy and build connection, (iii) Person-centred approach: adapting ways of working to the individual, (iv) Empowering instead of ‘fixing’ service users. 2) Distinctive features: The centrality of an individualised approach, facilitating recovery through sharing lived experiences and building connection. PSWs advocated for service-user needs and most worked in non-clinical ways, offering holistic, recovery-orientated support. Tensions could arise with more clinical approaches. 3) Impacts: Participants thought that peer support helped service users feel understood, leading to greater openness and facilitating recovery, although some felt that it may not be right for everyone. The role had benefits for participants’ own recovery, although its emotional demands could lead to burnout. Participants felt that PSWs could bring systemic improvements to services and use their lived experience to help teams meet service user needs. Conclusion PSWs work in a range of ways, but, a unifying feature is a flexible, person-centred approach, facilitating recovery through shared lived experience. A range of potential benefits of peer work were identified for PSWs and for service users, as well as reports of positive systemic change. These could be facilitated by recovery-orientated models in services, space for shared learning with PSWs, and flexibility to incorporate PSWs’ unique ways of working. Clinical trial number Not applicable.
