Association between subjective cognitive decline and life-space mobility in a community-based elderly adults: a moderated mediation model of depression and perceived social support.

ABSTRACT:

Background

Life-space mobility (LSM) is a critical health indicator in older adults, the mechanisms underlying the relationship between subjective cognitive decline (SCD) and LSM remain unclear.

Aims

This study examined depression as a mediator between SCD and LSM, and assessed whether perceived social support (PSS) moderates the relationship between SCD and depression among Chinese community-dwelling older adults.

Methods

We seek to elucidate psychosocial mechanisms of the SCD-LSM link and inform targeted intervention strategies. Drawing on a face-to-face interview sample of 287 community-dwelling aged, this cross-sectional study utilised a moderated mediation analysis. Key constructs were evaluated by the Subjective Cognitive Decline Questionnaire-9, 15-item geriatr
