How to improve the transferability of a 12-week home-space sedentary behaviour intervention for ethnically diverse older adults: a qualitative study protocol of key stakeholder perspectives.

Introduction: In the UK, the number of ethnically diverse older adults (OA) is growing. These individuals suffer complex health issues that are made worse by socioeconomic status, acculturation experiences and language barriers. Additionally, this varied group is the least active and a highly sedentary subgroup in the general population, which poses serious health concerns. Various interventions have been implemented with OAs to reduce their sedentary behaviour (SB) and enhance their physical activity (PA). However, there is still limited research that implements stakeholders' perceptions in translating the interventions into real-life settings, particularly for ethnically diverse OAs. Therefore, the current study aims to explore stakeholders' perceptions of the transferability of a 12-week home space intervention for ethnically diverse sedentary OAs, that is, aimed at reducing their SB and increasing their PA.

Methods: Exploratory qualitative research using in-depth interviews (IDIs) and a purposive sampling technique will be employed to recruit stakeholders. Before conducting the IDIs, the primary researcher (NAAM) will discuss the findings of the 12-week home space intervention study for ethnically diverse OAs to explain the intervention, and then the interview will revolve around the transferability of the intervention to transfer the intervention into real-world practice into the stakeholder contexts. A diverse group of stakeholders from Swansea, Wales, UK, representing a range of roles including health promotion professionals, programme leads, service providers, policymakers and researchers will be included. The qualitative data obtained will be analysed using reflexive thematic analysis.

Ethics And Dissemination: Stakeholders will be required to provide written informed consent prior to initiation of the study. Ethical approval for this study has been obtained from the College of Engineering Research Ethics Committee (320249732903), Swansea University. The study's results will be shared with the scientific community through a peer-reviewed journal publication and with study participants through seminars and workshops.
