Abstract

Physical activity (PA) is central to maintaining health and wellbeing as we age. Valid, reliable measurement tools are vital for understanding, and evaluating PA. There are presently limited options for comprehensively, accurately and affordably measuring older adults’ PA at scale. We aimed to develop a digital PA measurement tool specifically for adults aged 65+ using a person-based approach. We collated evidence from target users, field experts and relevant literature to learn how older adults comprehend PA and would accept a digital tool. Findings suggest older adults’ PA is often integrated into their daily life activities and that commonly applied terminology (e.g. moderate and vigorous) can be difficult to interpret. We also found there is increasing familiarity with digital platforms amongst older adults, and that technological simplicity is valued. These findings informed the development of a digital tool that asks users to report their activities across key PA domains and dimensions from the previous 7-days. Users felt the tool easy to navigate and comprehensive in terms of activity reporting. However, real world usability testing revealed that users struggled with seven-day recall. Further work will address issues identified, including creating a single-day reporting option, before commencing work to validate this new tool.
