"Now I Am Walking Toward Health": A Qualitative Study About the Outcomes of Physical Activity Participation That Matter to Older Adults.

Abstract

Randomized controlled trials that deliver physical activity interventions have demonstrated benefits for older adults across numerous health outcomes. However, too little attention has been directed to ensuring that such trials are measuring patient-relevant outcomes. To support outcome selection for future trials, the objective of this study was to understand what outcomes related to their physical activity participation older adults find important. We conducted 12 semistructured interviews with adults aged 65years and older and analyzed interview transcripts with a reflexive thematic analysis. Older adults desired diverse outcomes from their physical activity participation, ranging from generic (e.g.,quality of life) to specific (e.g.,leg strength). Relevant outcomes were classified under five themes: physical, clinical, social, psychological, and overarching, each with respective subthemes. The outcomes that older adults found important were plentiful and rooted in a desire to improve their quality of life. Some of the outcome themes have been reported frequently in past trials (e.g.,physical), but others have not (e.g.,social). Future researchers should be aware of, and responsive to, the priorities of older adults when designing trials and defining outcomes. Significance/Implications: This study will help to improve outcome selection for future trials of physical activity with older adults. In alignment with a patient-oriented research philosophy, this study will also ground future outcome selection in the priorities of older adults.
