SUpporting wellbeing through PEeR-Befriending (SUPERB) feasibility trial: fidelity of peer-befriending for people with aphasia.

ABSTRACT:

Objective

To evaluate systematically the fidelity of a peer-befriending intervention for people with aphasia.

Design

SUpporting wellbeing through Peer-befriending (SUPERB) was a feasibility randomised controlled trial comparing usual care to usual care +peer-befriending. This paper reports on the fidelity of all intervention aspects (training and supervision of providers/befrienders; intervention visits) which was evaluated across all areas of the Behaviour Change Consortium framework.

Setting

Community.

Participants

People with aphasia early poststroke and low levels of distress, randomised to the intervention arm of the trial (n=28); 10 peer-befrienders at least 1-year poststroke.

Intervention

Peer-befrienders were trained (4-6 hours); and received regular supervision (monthly group while actively befriending, and one-to-one as and when needed) in order to provide six 1-hour peer-befriending visits over 3 months.

Main measures

Metrics included number and length of training, supervision sessions and visits. All training and supervision sessions and one (of six) visits per pair were rated against fidelity checklists and evaluated for inter-rater and intrarater reliability (Gwets AC1 agreement coefficient). Per-cent adherence to protocol was evaluated.

Results

All peer-befrienders received 4-6 hours training over 2-3 days as intended. There were 25 group supervision sessions with a median number attended of 14 (IQR=8-18). Twenty-six participants agreed (92.8%) to the intervention and 21 (80.8%) received all six visits (median visit length 60 min). Adherence was high for training (91.7%-100%) and supervision (83%-100%) and moderate-to-high for befriending visits (66.7%-100%). Where calculable, inter-rater and intrarater reliability was high for training and supervision (Gwets AC1 >0.90) and moderate-to-high for intervention visits (Gwets AC1 0.44-1.0).

Conclusion

Planning of fidelity processes at the outset of the trial and monitoring throughout was feasible and ensured good-to-high fidelity for this peer-befriending intervention. The results permit confidence in other findings from the SUPERB trial.

Project description:ObjectiveTo determine the feasibility and acceptability of peer-befriending, for people with aphasia.DesignSingle-blind, parallel-group feasibility randomised controlled trial comparing usual care to usual care + peer-befriending.Participants and settingPeople with aphasia post-stroke and low levels of distress, recruited from 5 NHS Hospitals and linked community services; their significant others; and 10 befrienders recruited from community.InterventionSix 1-hour peer-befriending visits over three months.Main measuresFeasibility parameters included proportion eligible of those screened; proportion consented; missing data; consent and attrition rates. Acceptability was explored through qualitative interviews. Outcomes for participants and significant others were measured at baseline, 4- and 10-months; for peer-befrienders before training and after one/two cycles of befriending.ResultsOf 738 patients identified, 75 were eligible of 89 fully screened (84%), 62 consented (83% of eligible) and 56 randomised. Attrition was 16%. Adherence was high (93% attended ⩾2 sessions, 81% all six). The difference at 10 months on the GHQ-12 was 1.23 points on average lower/better in the intervention arm (95% CI 0.17, -2.63). There was an 88% decrease in the odds of GHQ-12 caseness (95% CI 0.01, 1.01). Fourty-eight significant others and 10 peer-befrienders took part. Procedures and outcome measures were acceptable. Serious adverse events were few (n = 10, none for significant others and peer-befrienders) and unrelated.ConclusionsSUPERB peer-befriending for people with aphasia post-stroke experiencing low levels of distress was feasible. There was preliminary evidence of benefit in terms of depression. Peer-befriending is a suitable intervention to explore further in a definitive trial.Clinical trial registration-URL: http://www.clinicaltrials.gov Unique identifier: NCT02947776Subject terms: Translational research, mental health, rehabilitation, quality and outcomes, stroke.

Project description:BackgroundDespite the high prevalence of mood problems after stroke, evidence on effective interventions particularly for those with aphasia is limited. There is a pressing need to systematically evaluate interventions aiming to improve wellbeing for people with stroke and aphasia. This study aims to evaluate the feasibility of a peer-befriending intervention.Methods/designSUPERB is a single blind, parallel group feasibility trial of peer befriending for people with aphasia post-stroke and low levels of psychological distress. The trial includes a nested qualitative study and pilot economic evaluation and it compares usual care (n = 30) with usual care + peer befriending (n = 30). Feasibility outcomes include proportion screened who meet criteria, proportion who consent, rate of consent, number of missing/incomplete data on outcome measures, attrition rate at follow-up, potential value of conducting main trial using value of information analysis (economic evaluation), description of usual care, and treatment fidelity of peer befriending. Assessments and outcome measures (mood, wellbeing, communication, and social participation) for participants and significant others will be administered at baseline, with outcome measures re-administered at 4 and 10 months post-randomisation. Peer befrienders will complete outcome measures before training and after they have completed two cycles of befriending. The qualitative study will use semi-structured interviews of purposively sampled participants (n = 20) and significant others (n = 10) from both arms of the trial, and all peer befrienders to explore the acceptability of procedures and experiences of care. The pilot economic evaluation will utilise the European Quality of life measure (EQ-5D-5 L) and a stroke-adapted version of the Client Service Receipt Inventory (CSRI).DiscussionThis study will provide information on feasibility outcomes and an initial indication of whether peer befriending is a suitable intervention to explore further in a definitive phase III randomised controlled trial.Trial registrationClinicalTrials.gov identifier NCT02947776, registered 28th October 2016.

Project description:BackgroundWhile people who are homeless often experience poor mental and physical health and problem substance use, getting access to appropriate services can be challenging. The development of trusting relationships with non-judgemental staff can facilitate initial and sustained engagement with health and wider support services. Peer-delivered approaches seem to have particular promise, but there is limited evidence regarding peer interventions that are both acceptable to, and effective for, people who are homeless and using drugs and/or alcohol. In the proposed study, we will develop and test the use of a peer-to-peer relational intervention with people experiencing homelessness. Drawing on the concept of psychologically informed environments, it will focus on building trusting and supportive relationships and providing practical elements of support such as access to primary care, treatment and housing options.MethodsA mixed-method feasibility study with concurrent process evaluation will be conducted to explore the feasibility and acceptability of a peer-delivered, relational intervention for people with problem substance use who are homeless. Peer Navigators will be based in homelessness outreach and residential services in Scotland and England. Peer Navigators will work with a small number of participants for up to 12 months providing both practical and emotional support. The sample size for the intervention is 60. Those receiving the intervention must be currently homeless or at risk of homelessness, over the age of 18?years and self-report alcohol/drug problems. A holistic health check will be conducted in the first few months of the intervention and repeated towards the end. Health checks will be conducted by a researcher in the service where the Peer Navigator is based. Semi-structured qualitative interviews with intervention participants and staff in both intervention and standard care settings, and all Peer Navigators, will be conducted to explore their experiences with the intervention. Non-participant observation will be conducted in intervention and standard care sites to document similarities and differences between care pathways.DiscussionThe SHARPS study will provide evidence regarding whether a peer-delivered harm reduction intervention is feasible and acceptable to people experiencing homelessness and problem substance use in order to develop a definitive trial.Trial registrationSRCTN registry ISRCTN15900054, protocol version 1.3, March 12, 2018.

Project description:BACKGROUND:During the transition between prison and community, people are at greatly increased risk for adverse health outcomes. This study describes a peer health mentoring program that supports women in the first 3 days after their release from a provincial correctional facility in British Columbia. METHODS:We used a participatory health research framework to develop multimethod processes to describe the Unlocking the Gates Peer Health Mentoring Program. Mentors are women with incarceration experience. Between 2013 and 2018, women released from Alouette Correctional Centre for Women were invited to access the program. All program clients were invited to participate in the surveys and interviews. We analyzed survey and interview data using descriptive analysis for quantitative data and content analysis for qualitative data. RESULTS:There were 346 program contacts from 340 women over the study period. For every contact, a telephone interview was conducted. Among the 346 contacts, 173 women met their mentor, of whom 172 (99.4%) completed the intake and consent forms. A total of 105 women (61.0%) completed a program activity feedback survey at the end of the mentoring period. Women identified a range of needed supports during the transition from prison to community, including access to clothing, social assistance, housing and health care. Participants described a mix of emotions surrounding release, including excitement, anxiety, hope, and a wish for understanding and support. Within 3 days of release, 49 participants (46.7%) had accessed a family physician, and 89 (84.8%) had accessed at least 1 community resource. Ninety-eight participants (93.3%) reported that their mentor assisted them in accessing community resources. INTERPRETATION:Peer health mentoring provides valuable, multifaceted support in helping women to navigate health and social services and to meet their basic needs. Strengthening health supports during the transition from prison to community is critical to promoting the health and well-being of women leaving prison.

Project description:IntroductionText-to-speech (TTS) technology is a possible reading support for people with aphasia; however, adoption for functional reading remains rare, and people with aphasia may have limited knowledge about TTS. Given this situation coupled with inherent communication challenges associated with aphasia, the purpose of this convergent mixed methods study was to explore the perceptions of participants about desired features, benefits, and drawbacks of TTS technology after having engaged in one-on-one education and guided practice activities.MethodsNineteen adults with chronic aphasia completed a single education and guided practice session followed by close-ended questions and participation in a semi-structured interview to explain preferences, concerns, beliefs, and opinions about potential TTS technology benefits and drawbacks. Three participants had previously used TTS technology for functional reading; all others had some prior exposure but did not use a system for functional purposes.ResultsSeventeen of 19 participants expressed TTS technology interest after education and guided practice activities. Participants endorsed selection of a preferred voice, control of speech output rate, and highlighting as priority features. Frequently endorsed benefits were improved comprehension and increased reading independence; some participants believed they would succeed in reading a greater variety of materials, communicate more with others, participate in more reading activities, and/or read faster. The greatest concern was mastering device operation; other concerns related to understanding the voice output, needing another person's help for system use, and matching the speech output rate to a preferred reading rate.ConclusionsOverall, most participants had positive perceptions about possible benefits afforded by TTS technology. Practitioners need to provide opportunities for people with aphasia to learn about and explore TTS systems to determine whether adoption is desired.

Project description:BackgroundThere is an ample body of literature examining the experiences and outcomes of peer support services for mental health recovery in western countries. However, formal peer support is only recently adapted and piloted to alleviate depression among older people, and little is known about how the peer-to-peer model might be lived out in the older Chinese population. This qualitative study investigated peer supporters' (PS) perspectives of their roles and experiences of rendering formal peer support to community-dwelling older adults at risk of or living with depression in Hong Kong.MethodsThe study adopted a qualitative design. Five semi-structured focus groups were conducted with 27 trained peer supporters between ages 54-74 (21 females and 6 males) who had provided peer-to-peer support to older adults at risk of or living with depression in the community for at least 12 months. Thematic analysis was employed to derive content and meanings from the focus group transcripts.ResultsParticipants' mean age was 61.9 years; two-thirds of them were retired and the rest still engaged in part-time or full-time employment. Four themes were identified in relations to the roles and experiences in rendering the peer support services: (1) peerness in health and age-related lived experiences; (2) companionship, social and emotional ties beyond formal support; (3) meaningful roles to facilitate older people's functional ability; and (4) hopes and actions against the undesirable outcomes of aging. Being a PS might provide meaningful roles for persons in transition to or living in late adulthood, and enable community-dwelling older adults with depression to maintain functional ability. On the other hand, defining the concept of 'peer' beyond the shared experience of mental distress, ensuring a healthy boundary between the peers and the service users, maintaining a careful balance between time-limited formal support and stable social ties, and providing self-management training and on-going support appear crucial.ConclusionsThis study of PS' perspectives and experiences offer insights into the age-specific dimension of the peer relationship. Despite the promising effects it might offer, careful implementation of peer support among older adults is warranted to safeguard against the ensuing loss of meaningful social ties and the potential emotional distress.
