The influence of ethnic group composition on focus group discussions.

BACKGROUND: Focus groups are commonly used to explore participants' experiences in health and social care research. Although it is suggested that having demographically homogenous groups may help put participants at ease, the evidence is sparse.The aims of the paper are to: explore the impact of relative ethnic homogeneity and heterogeneity of focus group participants on the group discussions; improve understanding of homogeneity and heterogeneity in focus groups; suggest ways to operationalise concepts such as being 'more comfortable' with other focus group participants. METHOD: Digitally recorded focus groups were undertaken with family carers of stroke survivors and were later transcribed and analysed using framework analysis. Groups were designated as more or less ethnically homogenous. More homogenous groups included, for example, only White British or Asian Indian participants whilst more heterogeneous groups comprised a mixture of, for example, Asian, White British and Black Caribbean participants. RESULTS: Forty-one carers participated in seven focus groups. Analysis revealed differences in discussions around ethnicity between the more or less ethnically homogenous groups. For example, participants in more ethnically homogenous focus groups were more likely to say ethnicity might influence perceptions of social care services. On the other hand, more heterogeneous groups emphasised similarity in carers' experiences, irrespective of ethnicity. Participants in the more homogenous groups were also more likely to make potentially controversial comments relating to ethnic differences. Additionally they appeared to be more at ease with each other discussing the topic. For example, they spontaneously mentioned ethnic differences earlier in these groups.In contrast, analysis of topics not specifically related to ethnicity, such as the difficult experiences of being a carer, produced no discernible patterns when comparing more and less homogenous focus groups. CONCLUSION: Considerations around focus group participant demographic homogeneity and heterogeneity are complex and these terms may be most usefully applied only in relative terms. Data derived from more homogenous groups complement data from more heterogeneous groups providing different perspectives. Depending on the focus of the discussion, having characteristics in common, such as being a carer can override other differences

Search for eccentric black hole coalescences during the third observing run of LIGO and Virgo

Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M>70 M⊙) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0<e≤0.3 at 0.33 Gpc−3 yr−1 at 90\% confidence level

Ultralight vector dark matter search using data from the KAGRA O3GK run

Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM

New ways of working in mental health services: a qualitative, comparative case study assessing and informing the emergence of new peer worker roles in mental health services in England

Background: A variety of peer worker roles are being introduced into the mental health workforce in England, in a range of organisational contexts and service delivery settings. The evidence base demonstrating the effectiveness of peer worker-based interventions is inconclusive and largely from outside England. An emerging qualitative literature points to a range of benefits, as well as challenges to introducing the peer worker role. Aims: In this study we aimed to test the international evidence base, and what is known generally about role adoption in public services, in a range of mental health services in England. We also aimed to develop organisational learning supporting the introduction of peer worker roles, identifying learning that was generic across mental health services and that which was specific to organisational contexts or service delivery settings. Team: The research was undertaken by a team that comprised researchers from a range of academic and clinical disciplines, service user researchers, a peer worker, and managers and service providers in the NHS and voluntary sector. Service user researchers undertook the majority of the data collection and analysis. We adopted a coproduction approach to research, integrating the range of perspectives in the team to shape the research process and interpret our findings. Study design: The study employed a qualitative, comparative case study design. We developed a framework, based on existing evidence and the experiential insight of the team, which conceptualised the challenges and facilitators of introducing peer worker roles into mental health services. The framework was used to inform data collection and to enable comparisons between different organisational contexts, service delivery settings and the perspectives of different stakeholders. Settings: The study took place in 10 contrasting cases comprising mental health NHS trusts, voluntary sector service providers and partnerships between the NHS and voluntary sector or social care providers. Peer workers were employed in a variety of roles, paid and unpaid, in psychiatric inpatient settings, community mental health services and black and minority ethnic (BME)-specific services. Participants: Participants were 89 people involved in services employing peer workers, recruited purposively in approximately equal proportion from the following stakeholder groups: service users; peer workers; (non-peer) coworkers; line managers; strategic managers; and commissioners. Data collection: All participants completed an interview that comprised structured and open-ended questions. Structured questions addressed a number of domains identified in the existing evidence as barriers to, or facilitators of, peer worker role adoption. Open-ended questions elicited detailed data about participants’ views and experiences of peer worker roles. Data analysis: Structured data were analysed using basic statistics to explore patterns in implementation across cases. Detailed data were analysed using a framework approach to produce a set of analytical categories. Patterns emerging in the structured analysis informed an in-depth interrogation of the detailed data set, using NVivo 9 qualitative software (QSR International Pty Ltd, Victoria, Australia) to compare data between organisational contexts, service delivery settings and stakeholder groups. Preliminary findings were refined through discussion with a range of stakeholders at feedback workshops. Findings: Many of the facilitators of peer worker role adoption identified in the existing evidence base were also evident in mental health services in England, although there were issues around pay, leadership, shared understanding of the role, training and management where good practice was uneven. A number of examples of good practice were evident in the voluntary sector, where peer worker roles had been established for longer and organisations were more flexible. In the NHS there were a range of challenges around introducing peer worker roles into existing structures and cultures of practice. Peer workers were able to engage people with services by building relationships based on shared lived experience – the language they used was particularly important in BME-specific services – but barriers to engagement could be created where roles were overformalised. Conclusions: Key barriers to, and facilitators of, peer worker role adoption were identified, including valuing the differential knowledge and practice that peer workers brought to the role (especially around maintaining personally, rather than professionally defined boundaries); maintaining peer identity in a role of work; changing organisational structures to support peer workers to remain well in their work; and challenging organisational cultures to empower peer workers to use their lived experience. Recommendations for future research include developing a theoretical framework articulating the change mechanisms underpinning ‘what peer workers do’, piloting and formally evaluating the effectiveness and cost-effectiveness of peer worker interventions, and mixed-method research to better understand the impact of working as a peer worker.

Introducing New Peer Worker Roles into Mental Health Services in England: Comparative Case Study Research Across a Range of Organisational Contexts

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
