Examines the mediation of cognitive impairment by psychological well-being in older adults, indicating significant psychosocial pathways.
Background: Physical frailty is a well-established risk factor for cognitive impairment, but the psychosocial mechanisms underlying this link remain insufficiently understood. Psychological well-being (PWB) may represent a modifiable pathway. This study examined whether PWB mediates the association between physical frailty and incident cognitive impairment, and whether this pathway varies by age or gender.
