Using Step Trackers Among Older People Receiving Aged Care Services Is Feasible and Acceptable: A Mixed-Methods...

Area of Science:

• Gerontology
• Digital Health
• Human-Computer Interaction

Background:

• Maintaining physical activity (PA) is crucial for older adults, especially those with frailty and mobility issues.
• Wearable activity trackers and digital feedback tools show potential for promoting PA but require further investigation in aged care settings.
• This study addresses the underexplored feasibility and acceptability of these technologies in aged care.

Purpose of the Study:

• To evaluate the feasibility and acceptability of using wearable and mobile devices for step tracking in aged care.
• To examine the usability of different interfaces (Fitbit, mobile app, website) for reviewing PA progress among older adults.
• To identify user experiences, benefits, and barriers associated with digital PA monitoring in aged care.

Main Methods:

• A mixed-methods feasibility study involving 14 participants aged 65+ from aged care services in NSW, Australia.
• Participants used a Fitbit Inspire 3 and a mobile app for four weeks to track steps across three interfaces: Fitbit, mobile app, and study website.
• Feasibility assessed via enrolment/retention; acceptability via facilitator-led surveys, usability, comfort, motivation, and device preference questionnaires, with thematic analysis of open-ended responses.

Main Results:

• High feasibility demonstrated by 82% enrolment and 93% retention rates.
• Participants preferred the Fitbit device for its ease of use, visibility, and enjoyable experience compared to the mobile app or website.
• Step tracking enhanced PA awareness and confidence, with participants valuing reminders, rewards, and social sharing; barriers included illness and technical issues.

Conclusions:

• Wearable step trackers show promise for supporting physical activity in older adults receiving aged care.
• Strong acceptability suggests simple digital tools can enhance the reach and sustainability of mobility interventions in aged care systems.
• Future research should focus on long-term adherence, usability across diverse needs, and conditions for successful implementation and scale-up.
