BackgroundThe provision of peer support as a component of mental health care, including the employment of Peer Workers (consumer-providers) by mental health service organisations, is increasingly common internationally. Peer support is strongly advocated as a strategy in a number of UK health and social care policies. Approaches to employing Peer Workers are proliferating. There is evidence to suggest that Peer Worker-based interventions reduce psychiatric inpatient admission and increase service user (consumer) empowerment. In this paper we seek to address a gap in the empirical literature in understanding the organisational challenges and benefits of introducing Peer Worker roles into mental health service teams.MethodsWe report the secondary analysis of qualitative interview data from service users, Peer Workers, non-peer staff and managers of three innovative interventions in a study about mental health self-care. Relevant data was extracted from interviews with 41 participants and subjected to analysis using Grounded Theory techniques. Organisational research literature on role adoption framed the analysis.ResultsPeer Workers were highly valued by mental health teams and service users. Non-peer team members and managers worked hard to introduce Peer Workers into teams. Our cases were projects in development and there was learning from the evolutionary process: in the absence of formal recruitment processes for Peer Workers, differences in expectations of the Peer Worker role can emerge at the selection stage; flexible working arrangements for Peer Workers can have the unintended effect of perpetuating hierarchies within teams; the maintenance of protective practice boundaries through supervision and training can militate against the emergence of a distinctive body of peer practice; lack of consensus around what constitutes peer practice can result in feelings for Peer Workers of inequality, disempowerment, uncertainty about identity and of being under-supported.ConclusionsThis research is indicative of potential benefits for mental health service teams of introducing Peer Worker roles. Analysis also suggests that if the emergence of a distinctive body of peer practice is not adequately considered and supported, as integral to the development of new Peer Worker roles, there is a risk that the potential impact of any emerging role will be constrained and diluted.

An empirically and theoretically grounded change model can be articulated that usefully informs the development, evaluation and planning of peer worker interventions.

Purpose Peer support is increasingly being introduced into mainstream mental health services internationally. The distinctiveness of peer support, compared to other mental health support, has been linked to values underpinning peer support. Evidence suggests that there are challenges to maintaining those values in the context of highly standardised organisational environments. The purpose of this paper is to describe a “principles-based” approach to developing and evaluating a new peer worker role in mental health services. Design/methodology/approach A set of peer support values was generated through systematic review of research about one-to-one peer support, and a second set produced by a UK National Expert Panel of people sharing, leading or researching peer support from a lived experience perspective. Value sets were integrated by the research team – including researchers working from a lived experience perspective – to produce a principles framework for developing and evaluating new peer worker roles. Findings Five principles referred in detail to: relationships based on shared lived experience; reciprocity and mutuality; validating experiential knowledge; leadership, choice and control; discovering strengths and making connections. Supporting the diversity of lived experience that people bring to peer support applied across principles. Research limitations/implications The principles framework underpinned development of a handbook for a new peer worker role, and informed a fidelity index designed to measure the extent to which peer support values are maintained in practice. Given the diversity of peer support, the authors caution against prescriptive frameworks that might “codify” peer support and note that lived experience should be central to shaping and leading evaluation of peer support. Originality/value This paper adds to the literature on peer support in mental health by describing a systematic approach to understanding how principles and values underpin peer worker roles in the context of mental health services. This paper informs an innovative, principles-based approach to developing a handbook and fidelity index for a randomised controlled trial. Lived experiences of mental distress brought to the research by members of the research team and the expert advisors shaped the way this research was undertaken.

There are a subset of short gamma-ray bursts (SGRBs) which exhibit a rebrightening in their high-energy light curves known as extended emission. These bursts have the potential to discern between various models proposed to describe SGRBs as any model needs to account for extended emission. In this paper, we combine fallback accretion into the magnetar propeller model and investigate the morphological changes fallback accretion has on model light curves and fit to the afterglows of 15 SGRBs exhibiting extended emission from the Swift archive. We have parameterised the fallback in terms of existing parameters within the propeller model and solved for the disc mass and angular frequency of the magnetar over time. We then apply a Markov chain Monte Carlo routine to produce fits to the data. We present fits to our extended emission SGRB sample that are morphologically and energetically consistent with the data provided by Swift BAT and XRT telescopes. The parameters derived from these fits are consistent with predictions for magnetar properties and fallback accretion models. Fallback accretion provides a noticeable improvement to the fits of the light curves of SGRBs with extended emission when compared to previous work and could play an important role in explaining features such as variability, flares and long dipole plateaux.

A wide variety of peer worker roles is being introduced into mental health services internationally. Empirical insight into whether conditions supporting role introduction are common across organisational contexts is lacking. A qualitative, comparative case study compared the introduction of peer workers employed in the statutory sector, voluntary sector and in organisational partnerships. We found good practice across contexts in structural issues including recruitment and training, but differences in expectations of the peer worker role in different organisational cultures. Issues of professionalism and practice boundaries were important everywhere but could be understood very differently, sometimes eroding the distinctiveness of the role.
