Physical resilience as a moderator of the relationship between frailty and disability in older adults with osteoarthritis.

The findings emphasize the detrimental effects of osteoarthritic symptoms on disability through frailty, and the moderated mediation results suggest that these effects were conditional on physical resilience, which is a modifiable internal resource of individuals. When planning nursing interventions for older adults with osteoarthritis, nurses need to consider physical resilience as a moderator to prevent frailty and disability.
