Abstract
Physical exercise and cognitive training have the potential to enhance cognitive function and mobility in older adults at risk of dementia. However, little is known about the experience of receiving such interventions in the home settings of older adults. Fifteen participants (mean age 70.8 years) who completed the 16-week interventions of SYNERGIC@Home feasibility trial were interviewed to understand participants' engagement in home-based physical and cognitive exercise interventions delivered one-on-one through videoconferencing. Grounded theory data analysis was completed collaboratively by qualitative researchers. Results show that participants' engagement was driven by personal connection to dementia and mediated by relationships fostered largely with individual exercise trainers. Participants were also invested in the greater good (wanting their participation to make a difference to dementia research), their own outcomes, or their family's and society at large. Overall, they reflected on their participation as a rich learning experience. We propose that the quality of interpersonal connections and personalized support are of primary importance for older adults to stay engaged in physical exercise and cognitive training programs delivered remotely.
