Investigating the association between assistive device use and the change in life satisfaction among community-dwelling older adults: analysis of The Canadian Longitudinal Study on Aging (CLSA)

The non-significant findings may partly be explained by the fact that a majority of the study sample reported high LS scores and low usage of AD. Nonetheless, null findings are valuable as they can guide future research and prevent biased policies and practices. Future research can employ longer follow-up periods, collect data on additional confounding factors such as device satisfaction, conduct analyses by specific device type (e.g. mobility devices versus vision-related devices), and use refined LS questions related to AD use to structure future studies towards investigating LS in the context of AD use.
