Trial feasibility and process evaluation of a motivationally-embellished group peer led walking intervention in retirement villages using the RE-AIM framework: the residents in action trial (RiAT)

Effectiveness of a supervised group-based walking program on physical, psychological and social outcomes among older adults: a randomised controlled trial protocol

INTRODUCTION

To minimise adverse health events among older adults, physical activity (PA) is considered one of the most fundamental and effective forms of lifestyle. Therefore, an urgent effort to promote a physically active lifestyle among our older adults is needed, in which walking could be a better choice, especially for mass promotion. Besides, the types of PA interventions were also shown to affect their effectiveness on older adults' psychosocial outcomes. Hence, the overall aim of the project is to examine the effectiveness of supervised group-based walking intervention by comparing it with unsupervised group-based walking and unsupervised individual-based walking interventions on improving physical, psychological and social outcomes among older adults in Hong Kong.

METHODS AND ANALYSIS

The research will conduct a four-group (supervised group-based, unsupervised group-based walking, unsupervised individual-based, control group), double-blind, randomised control trial, targeting 184 older adults in Hong Kong. The primary outcomes will be measured by participants' changes in resting heart rates, body compositions, resting blood pressures, walking performance, loneliness, perceived social support and PA enjoyment. The results will be analysed using repeated analysis of variance and one-way analysis of covariance, as well as by conducting in-depth interviews with selected participants. Also, the outcomes of the research will be used as references for designing an effective walking operation manual for promoting healthy ageing among older adults in the community.

ETHICS AND DISSEMINATION

The current study involves human participants, and the research protocol has been approved by the research ethics committee at Hong Kong Baptist University (Ref: R2022-2023-0013). All participants will be provided with written informed consent to participate. The outcomes of the intervention protocol will be disseminated through manuscript publications.

TRIAL REGISTRATION NUMBER

The trial is registered at the ClinicalTrials.gov PRS (Trial ID: NCT05907252; date of first posted: 16 June 2023).

A Nature-Based Intervention for Promoting Physical Activity in Older Adults: A Qualitative Study Using the COM-B Model

Physical inactivity contributes to over 800,000 deaths annually. Numerous non-pharmacological interventions provide a route to address this behavioural risk factor linked to the growth of non-communicable diseases. Here, we consider a nature-based intervention, specifically group outdoor health walks (GOHW), as a non-pharmacological intervention to increase physical activity and contribute to health and quality of life amongst older adults. We used the theoretically grounded Capability, Opportunity, Motivation, and Behaviour (COM-B) model as a lens to examine interviews with participants in a GOHW with an activity tracker and signposted by health clinics in Scotland, UK. Analysis identified capabilities, opportunities, and motivations, their impact on behaviour, and perceived physical and mental health. The application of the COM-B model to intervention evaluation allowed us to examine two separate behaviours, that of (i) engaging with the intervention itself, and (ii) incorporating the behaviour into one's life that the intervention targets. Analysis identified emerging capabilities, opportunities, and motivations that supported additional health-promoting behaviours, including increased time outdoors in nature and leadership to self-organise continued group walks. We offer insight into the design of nature-based interventions to effectively engage older adults with chronic health conditions and foster personal behaviour change for health and well-being.

A Mixed Methods Evaluation of a Pilot Multidisciplinary Breathlessness Support Service

Breathlessness support services have demonstrated benefits for breathlessness mastery, quality of life and psychosocial outcomes for people living with breathlessness. However, these services have predominantly been implemented in hospital and home care contexts. This study aims to evaluate the adaptation and implementation of a hospice-based outpatient Multidisciplinary Breathlessness Support Service (MBSS) in Ireland. A sequential explanatory mixed methods design guided this study. People with chronic breathlessness participated in longitudinal questionnaires (n = 10), medical record audit (n = 14) and a post-discharge interview (n = 8). Caregivers (n = 1) and healthcare professionals involved in referral to (n = 2) and delivery of (n = 3) the MBSS participated in a cross-sectional interview. Quantitative and qualitative data were integrated deductively via the pillar integration process, guided by the RE-AIM framework. Integration of mixed methods data enhanced understanding of factors influencing the reach, adoption, implementation and maintenance of the MBSS, and the potential outcomes that were most meaningful for service users. Potential threats to the sustainability of the MBSS related to potential preconceptions of hospice care, the lack of standardized discharge pathways from the service and access to primary care services to sustain pharmacological interventions. This study suggests that an adapted multidisciplinary breathlessness support intervention is feasible and acceptable in a hospice context. However, to ensure optimal reach and maintenance of the intervention, activities are required to ensure that misconceptions about the setting do not influence willingness to accept referral to MBSS services and integration of services is needed to enable consistency in referral and discharge processes.

A seniors exercise park program for older adults with mild balance dysfunction - a feasibility study

PURPOSE

To evaluate the feasibility of a multimodal exercise program conducted at a Seniors Exercise Park among older adults with mild balance dysfunction.

METHODS

Participants (aged ≥65 years) with mild balance dysfunction underwent 18 weeks of gradual reduction of supervised training followed by six weeks of independent training at the Seniors Exercise Park. Feasibility and safety were assessed at baseline, 18 and 24 weeks.

RESULTS

Seventy-five participants expressed interest in the program. Of the 46 participants enrolled in the study, 36 (78.3%) completed the 18 week intervention, and 32 (69.6%) were followed-up at 24 weeks. The median adherence to supervised training was 90.9%, and independent practice was 26.3% (weeks 19-24). All the supervised training sessions were completed within 18 weeks. No falls, or adverse events occurred. All physical performance (e.g., balance, lower body strength, and mobility), psychosocial health outcomes (e.g., mental wellbeing) and quality of life improved significantly at 18 and 24 weeks.

CONCLUSIONS

This initially supervised Seniors Exercise Park program which progressed to independent practice is feasible, safe, and improved health outcomes in older adults with mild balance dysfunction. Strategies are needed to improve adherence to independent practice and minimise dropouts. Implications for rehabilitationGradually reduced supervision in a Seniors Exercise Park program progressing to independent practice is feasible and safe for older adults with mild balance dysfunction.Seniors Exercise Parks can assist older adults with mild balance dysfunction to improve their balance, lower body strength, mobility, and psychosocial health.There is a need for more Seniors Exercise Parks in community parks to enable greater access to this novel exercise approach by older people, including those with mild balance dysfunction.

A qualitative longitudinal study of motivation in the REtirement in ACTion (REACT) physical activity intervention for older adults with mobility limitations

BACKGROUND

Physical activity (PA) is beneficial for older adults' health, however they remain the least active age group in the UK. This qualitative longitudinal study aims to understand motivations in older adults receiving the REACT physical activity intervention, through the lens of self-determination theory.

METHODS

Participants were older adults randomised to the intervention arm of the Retirement in ACTion (REACT) Study, a group-based physical activity and behaviour maintenance intervention to prevent decline of physical functioning in older adults (≥ 65 years). Stratified purposive sampling by physical functioning (Short Physical Performance Battery scores) and 3-month attendance was employed. Fifty-one semi-structured interviews were conducted at 6, 12 and 24-months with twenty-nine older adults (Mean age (baseline) = 77.9 years, SD 6.86, 69% female) and at 24-months with twelve session leaders and two service managers. Interviews were audio recorded, transcribed verbatim and analysed using Framework Analysis.

RESULTS

Perceptions of autonomy, competence and relatedness were associated with adherence to the REACT programme and maintenance of an active lifestyle. Motivational processes and participants' support needs, changed during the 12-month REACT intervention and across the 12-months post-intervention. Group interactions were an important source of motivation during the first six months but increased competence and mobility drove motivation at the later stages (12 months) and post-intervention (24 months).

CONCLUSIONS

Motivational support needs vary in different stages of a 12-month group-based programme (adoption and adherence) and post-intervention (long-term maintenance). Strategies to accommodate those needs include, (a) making exercise social and enjoyable, (b) understanding participants' capabilities and tailoring the programme accordingly, (c) capitalising on group support to motivate participants to try other activities and prepare sustainable active living plans.

TRIAL REGISTRATION

The REACT study was a pragmatic multi-centre, two-arm, single-blind, parallel-group, RCT (ISRCTN registration number 45627165).

The Feasibility of a Text-Messaging Intervention Promoting Physical Activity in Shift Workers: A Process Evaluation

Workplace health promotion programs (WHPPs) can improve shift workers' physical activity. The purpose of this paper is to present the process evaluation of a text messaging health promotion intervention for mining shift workers during a 24-day shift cycle. Data collected from intervention participants with a logbook (n = 25) throughout the intervention, exit interviews (n = 7) and online surveys (n = 17) examined the WHPP using the RE-AIM (Reach, Efficacy, Adoption, Implementation and Maintenance) framework. The program reached 66% of workers across three departments, with 15% of participants dropping out. The program showed the potential to be adopted if the recruitment strategies are improved to reach more employees, especially when involving work managers for recruitment. A few changes were made to the program, and participant adherence was high. Facilitators to adopt and implement the health promotion program included the use of text messaging to improve physical activity, feedback on behaviour, and providing incentives. Work-related fatigue was reported as a barrier to implementing the program. Participants reported that they would recommend the program to other workers and use the Mi fitness band to continue monitoring and improving their health behaviour. This study showed that shift workers were optimistic about health promotion. Allowing for long-term evaluation and involving the company management to determine scale-up should be considered for future programs.

Developing and evaluating a peer-based mental health literacy intervention with adolescent athletes

Widespread adolescent involvement in organized sport means that sport contexts are well-suited to 'actively' integrate prevention programs that may promote population-level change. This mixed methods study aimed to evaluate the feasibility and acceptability of a peer-based mental health literacy intervention. The intervention (i.e., Team Talk) was presented to eleven adolescent sport teams in the United States, with a total of 174 participants. Athlete participants completed surveys immediately before and after the intervention-including measures of workshop acceptability, social identity, and help-seeking behaviors. Semi-structured interviews were also conducted with a subset of five athletes, nine parents, and two coaches. With respect to recruitment as an indicator of feasibility, club-level adoption of the intervention was low, with difficulty recruiting clubs for intervention delivery. This signals that feasibility of the intervention-as it is currently designed and implemented by the research team-is low when considering similar competitive adolescent sport clubs and delivered as team-level workshops. Meanwhile, participants reported high acceptability of the intervention, and acceptability levels across participants was predicted by contextual factors related to implementation such as session duration. Regarding limited efficacy testing with measures completed before and after the intervention session: (a) social identity scores increased following the intervention, and (b) significant differences were not identified regarding efficacy to recognize symptoms of mental disorders. Athlete, coach, and parent interview responses also described potential adaptations to mental health programs. This research demonstrates the potential utility of peer-based mental health literacy interventions, while also revealing that further implementation research is necessary to adapt mental health literacy interventions to suit diverse adolescent sport contexts.

Intervention in Older Urban-Dwelling Veterans With Dysmobility: Protocol for a Pilot Feasibility Clinical Trial

BACKGROUND

The majority of older veterans do not meet the minimum healthy diet or physical activity recommendations despite known benefits. Identifying ways to increase adherence to programs that improve dietary quality and physical activity may reduce the risk of disability in older veterans. Peer-based interventions may be one method for facilitating lasting behavior change because peers often share a common culture and knowledge regarding problems their community experiences.

OBJECTIVE

This study aims to develop, pilot, and evaluate a theory-driven, 12-week, peer-led nutrition and exercise intervention that targets older veterans with dysmobility and assess its feasibility in 2 diverse urban areas with underrepresented populations.

METHODS

Community-dwelling veterans aged >65 years with self-reported dysmobility (defined as difficulty in at least 1 of the following: walking quickly across a street, walking a mile, ascending a flight of stairs, rising from a chair without the use of arms, or a fear of falling) from 2 Department of Veterans Affairs Geriatric Research, Education, and Clinic Centers (Baltimore, Maryland, and San Antonio, Texas) will be eligible to participate. First, this study will use validated mixed methods via web-based surveys (n=50 per site) to assess potential physical, social or environmental, and behavioral or lifestyle barriers that affect physical activity and dietary quality (phase 1). Next, we will use knowledge gained from these assessments and feedback from a focus group (n=10 per site) to adapt established Department of Veterans Affairs diet and exercise program materials to develop peer-led intervention materials and train peer leaders (n=3 per site). Finally, we will determine the feasibility and acceptability of the intervention to assess reach (recruitment and retention), adoption (satisfaction, perceived utility, attendance, and engagement), and implementation (fidelity of intervention), as well as the estimated magnitude and potential impact on selected outcomes (ie, diet quality and mobility) in 20 older veterans with dysmobility (n=10 per site).

RESULTS

The study was funded on January 1, 2022, with a projected data collection period of June 1, 2022, to December 31, 2023.

CONCLUSIONS

This study offers an innovative approach to identifying strategies that increase long-term adherence to lifestyle modification programs that improve dietary quality and physical activity in older veterans with dysmobility.

Health effects and cost-effectiveness of a multilevel physical activity intervention in low-income older adults; results from the PEP4PA cluster randomized controlled trial

Background

Older adults are the least active population in the U.S. Low-income communities have fewer physical activity (PA) resources, contributing to less PA and increased chronic disease risk. This study assessed the effect of the multilevel, peer-led, Peer Empowerment Program 4 Physical Activity (PEP4PA) on moderate-to-vigorous PA (MVPA) and health outcomes, over 2 years of follow up.

Methods

In a cluster-randomized controlled trial, 12 senior or community centers serving low-income older adults were assigned to a PA intervention (n = 6) or usual programming (n = 6) condition. PEP4PA included self-monitoring, health coaching, group walks, social support, and community advocacy to improve walking conditions. The primary outcome was daily minutes of MVPA (7-day accelerometer). Secondary outcomes included Perceived Quality of Life (PQoL), 6-Minute Walk Test (6-MWT), blood pressure (BP), and depressive symptoms at baseline, 6, 12, 18 and 24 months. Mixed effects regression models estimated the effects on outcomes between groups over time and included random effects for repeated measures and center clustering. Effect modification by sex and income status was assessed. We calculated the incremental cost per daily minute of MVPA gained in the intervention group relative to the control group to assess cost effectiveness.

Results

We enrolled 476 older adults (50 + years). Participants were on average 71 years old, 76% female, 60% low income, and 38% identified as racial or ethnic minorities. Compared to the control group, intervention participants sustained roughly a 10 min/day increase in MVPA from baseline at all time points and increased mean PQoL scores from unsatisfied at baseline to satisfied at 12, 18 and 24 months. Males and higher-income groups had greater improvements in MVPA. No significant effects were observed for 6-MWT or depressive symptoms, and BP results were mixed. The incremental cost per minute MVPA gained per person was $0.25, $0.09, $0.06, and $0.05 at 6, 12, 18 and 24 months, respectively.

Conclusions

PEP4PA achieved increases in MVPA and PQoL in low-income older adults, over 2 years of follow up. The peer-led, community-based intervention provides a sustainable and cost-effective model to improve health behaviors in underserved, aging populations.

Challenges to Engaging Older Adults in a Group-Based Walking Intervention: Lessons From the Residents in Action Trial

This qualitative research explored older adults' perceptions of participating in group-based walking programs set in independent-living retirement village contexts. Semistructured interviews were conducted with a subset of participants from the Residents in Action Trial. Data were analyzed through a combination of deductive and inductive thematic analysis. Findings were interpreted from a social identity perspective. Five themes were identified: (a) varying levels of social cohesion in retirement villages; (b) degree of shared identity between residents; (c) health, mobility, and preferred pace; (d) devotion to spouse; and (e) busy lives. When designing group-based walking interventions in retirement villages, it is important to consider community-level social cohesion and degree of relatedness between village residents. When attempting to build a sense of shared identity and relatedness between group members, researchers and policy makers should consider differing backgrounds, capabilities, schedules, and interests of participants.

Effectiveness of Peer-Led Wellbeing Interventions in Retirement Living: A Systematic Review

Retirement living (RL) communities may be an ideal setting in which to utilize peer-leaders to implement or support health and wellbeing interventions. To date, this literature has not been systematically summarized. The purpose of this study was to fill this gap with a particular focus on describing the extent to which interventions addressed each level of the social ecological model of behavior change. This review utilized established frameworks for assessing methodological quality of studies, including the CONSORT guidelines and RoB2 bias assessment for cluster randomized controlled trials. A total of 153 records were identified from database searches, and seven studies met inclusion criteria. Overall, there is emerging evidence that peer-led health and wellbeing programs in RL communities can positively impact both health behavior, such as increased physical activity or nutrition, and health status, such as lower blood pressure. The study quality was modest to very good, but only one study was deemed not to have a high risk of bias. Peers are generally cost-effective, more accessible, and relatable leaders for health interventions that can still produce impactful changes. Future studies are needed to better understand how to sustain promising interventions.

How can older peer leaders best support motivation for walking in physically inactive older adults? A self-determination theory perspective

OBJECTIVE

We aimed to determine what older adults perceive to be need-supportive behaviours of peer walk leaders, drawing primarily from Self-Determination Theory (SDT).

DESIGN

Experienced peer leaders (n = 13; Mage = 73.23, SD = 6.55) and walkers (n = 17; Mage = 72.88, SD = 5.79) were recruited from existing walking groups. Individuals who expressed an interest in becoming a peer leader (n = 18; Mage = 72.72, SD = 4.99) or walker (n = 20; Mage = 78.90, SD = 10.45) were recruited from retirement villages.

MAIN OUTCOME MEASURES

We conducted semi-structured interviews to identify leader behaviours that support autonomy, competence, and relatedness and analysed the data using framework analysis.

RESULTS

We identified eight main themes: eliciting walker interest, acknowledging and adapting to walkers' requirements, ensuring walkers feel comfortable, cared for, and socially integrated, supporting walker confidence, and promoting success experiences. Inexperienced leaders differed from other sub-groups in what they perceived to be supportive behaviours.

CONCLUSION

Future peer leaders could use the identified behaviours to help older adults feel motivated during group walks. New peer leaders can be educated about potential differences between what they describe as supportive and what walkers and experienced leaders perceive as need-supportive behaviours.

Volunteer Motivation and Retention of Older Peer Walk Leaders: A 4-Month Long Investigation

BACKGROUND AND OBJECTIVES

Peer volunteers offer a promising avenue for promoting physical activity in older adults. However, recruiting and retaining such volunteers are challenging. We aimed to examine longitudinally factors that determine whether older volunteer walk leaders will persist in their role.

RESEARCH DESIGN AND METHODS

We recruited older adults volunteering as walk leaders, from retirement villages in Perth, at the start of a 16-week walking intervention. Using a mixed-methods multiple case study design, informed by self-determination theory, we examined the motivational processes of three profiles: Dropouts, Completers, and Extenders. One male and 10 female (medianAge = 75 years, age range: 66-83 years) peer walk leaders were interviewed twice over 4 months, and data were analyzed using thematic analysis. Questionnaires provided information on volunteer characteristics, leadership confidence, and volunteer motivation.

RESULTS

Self-orientated goals, obligation and guilt, emotional exhaustion, lack of psychological need satisfaction, and perceived lack of support were barriers to volunteer persistence. Social confidence and relatedness satisfaction motivated volunteers to persist until program completion (Completers). Altruistic goals, using sustainable helping strategies, psychological need satisfaction, optimism, and enjoyment were important for continuing the role after the program (Extenders).

DISCUSSION AND IMPLICATIONS

Results describe how differences in volunteer motives, personal characteristics, and training may affect motivational processes that determine persistence as an older peer walk leader. We provide suggestions on selecting, training, and supporting older volunteer walk leaders to facilitate their retention.

Older Adults' Perceptions toward Walking: A Qualitative Study Using a Social-Ecological Model

Objectives: In this study, we aimed to investigate older adults’ perceptions of their walking experiences, using the social-ecological model as a guiding framework and to propose future walking intervention content. Methods: Thirty-eight participants (19 women; 47% from private elderly centers; mean age = 72.8 (SD = 7.4 years) took part in semi-structured interviews. Qualitative data analysis software QSR-NVivo was used for thematic coding. Results: Thematic deductive analysis revealed pertinent themes at the individual level (health benefits and barriers, fall risk, perseverance, and walking as a suitable activity for older adults), social environment level (social support and social interaction), physical environment level (density, land-use mix, and connectivity; perceived safety, pedestrian facilities (benches, quality of walking paths and sidewalks, and aesthetics), other pedestrian behaviors, and weather, and policy level (lack of walking programs in the community, and supportive culture for an active lifestyle). Discussion: Our findings provide insights for the planning of future multilevel walking intervention programs for older adults in Hong Kong. It is suggested that future walking intervention should include professionals (e.g., physiotherapist or coach) in a group setting, practical walking recommendations such as proper walking posture, and additional fun activities for older adults.

Effective Peer Leader Attributes for the Promotion of Walking in Older Adults

BACKGROUND AND OBJECTIVES

Peer-led interventions are promising for the promotion of physical activity behavior in older adults. However, little is known about the attributes of effective older peer leaders in such intervention programs. The objective was to determine what older adults perceive to be effective peer leader attributes.

RESEARCH DESIGN AND METHODS

A mixed-methods concurrent triangulation design was used. Participants, aged 60 years and older, were recruited from retirement villages and existing walking groups in Western Australia. They were predominantly white, Australian-born, female, healthy retirees. The sample consisted of four groups of older adults: those who had taken part in past peer-led walking programs (experienced walkers; n = 18), those interested in joining as walkers in a peer-led walking intervention (inexperienced walkers; n = 43), those interested to take on a peer leader role (inexperienced peer leaders; n = 25), and those who had already served as peer leaders (experienced peer leaders; n = 15). Questionnaires measured perceived effective leadership attributes, and physical activity was measured using ActivPAL devices (N = 101; Mage [SD] = 75.36 [7.59]). Semistructured interviews were conducted with the majority of participants (N = 68; Mage [SD] = 74.68 [7.78]).

RESULTS

Overall, participants described an effective peer leader as optimistic, compassionate, and friendly, but differences in perceptions were apparent between the groups.

DISCUSSION AND IMPLICATIONS

Our findings advance knowledge about important characteristics of an effective older peer leader, which can inform peer leader training, recruitment of peer leaders, and future scale development.

Mobilising people as assets for active ageing promotion: a multi-stakeholder perspective on peer volunteering initiatives

BACKGROUND

Successful peer volunteering is central to many community-based, active ageing initiatives. This study synthesises the perspectives of a range of stakeholders involved in peer volunteering initiatives and provides recommendations as to how peer volunteers can be effectively mobilised as community assets.

METHODS

An evidence synthesis of qualitative data from (a) the evaluation of ACE (Active, Connected, Engaged), a feasibility trial of a peer volunteering active ageing intervention, and (b) interviews with volunteers and managers of third sector organisations providing peer volunteering programmes. Data were analysed using directed content analysis.

RESULTS

Ten managers, 22 volunteers and 20 ACE participants were interviewed. The analysis identified six main themes, 33 higher and 22 sub themes. Main themes were: (i) Motives, (ii) Benefits, (iii) Skills and Characteristics, (iv) Challenges, (v) Training Needs, (vi) Recruitment and Retention. Altruism, changes in life circumstances, opportunities to reconnect with the community and personal fulfilment were the main reasons for volunteering. Volunteering was described as being personally rewarding, an avenue to acquire new skills and knowledge, and an opportunity for increased social connections and physical activity. Good peer volunteers are committed, reliable, have a good sense of humour, good interpersonal skills and are able to relate to participants. When pairing volunteers with participants, shared interests and geographical proximity are important to consider. Clarity of role, level of time commitment, regular feedback, recognition of effort and strong networks for on-going support are important strategies to facilitate volunteer retention.

CONCLUSIONS

The findings of this study support the value of peer volunteering as a strategy for mobilising community assets in promoting active ageing. To ensure success and longevity, these schemes require appropriate funding and efficient administrative support.

"It's Better Together": A Nested Longitudinal Study Examining the Benefits of Walking Regularly With Peers Versus Primarily Alone in Older Adults

The authors examined whether purposeful walking with peers at least once a week contributes to better behavioral and health outcomes in older adults than primarily walking alone. The authors used a longitudinal cohort design and recruited participants aged 60 years and older (N = 136) at the start of a 16-week walking intervention. Participants who walked on average at least once a week in the final 8 weeks of the intervention were included in the analysis (N = 79; 66 females, Mage [SD] = 77.73 [6.91]). The authors found that autonomous motivation, walking self-efficacy, functional capacity, body fat, and physical activity improved more in the walking with peers group compared with the walking alone group, after controlling for whether participants lived alone/with others and their health status. The results extend current literature by providing longitudinal evidence for the added benefits of regular peer-accompanied walking in older adults and highlight the importance of investing in peer-supported interventions.
