To examine how social support might moderate the relationship between intrinsic capacity and health-related quality of life (HRQoL) based on the buffering model of social support.
This was a cross-sectional study with a sample of 1181 Chinese community-dwelling older adults aged ≥ 60 years in 2016. Social support was assessed using the Social Support Rating Scale. Intrinsic capacity was assessed using the revised integrated care for older people screening tool. HRQoL was measured by the 12-item Short Form Health Survey. Hierarchical linear regression analysis was implemented to test the moderating effect of social support.
Support utilization attenuated the relationship between lower intrinsic capacity and poor physical HRQoL while subjective support attenuated the relationship between lower intrinsic capacity and poor mental HRQoL. However, objective support had no significant moderating effect on the relationship between intrinsic capacity and specific domains of HRQoL.
The moderating effects of social support on the association between intrinsic capacity and HRQoL vary by support types. Effective interventions should target the perception and utilization of available support among older adults with lower intrinsic capacity to maintain their physical and mental HRQoL.
基于社会支持的缓冲模型，考察社会支持可能如何调节内在能力与健康相关生活质量（HRQoL）之间的关系。
这是一项横断面研究，于 2016 年纳入了 1181 名年龄≥60 岁的中国社区居住的老年人。社会支持采用社会支持评定量表进行评估。内在能力采用修订后的老年人综合关怀筛选工具进行评估。HRQoL 通过 12 项简短健康调查进行测量。采用分层线性回归分析检验社会支持的调节作用。
支持利用度降低了内在能力较低与身体 HRQoL 较差之间的关系，而主观支持降低了内在能力较低与心理 HRQoL 较差之间的关系。然而，客观支持对内在能力与 HRQoL 特定领域之间的关系没有显著的调节作用。
社会支持对内在能力与 HRQoL 之间关联的调节作用因支持类型而异。对于内在能力较低的老年人，有效的干预措施应针对他们对现有支持的感知和利用，以维持他们的身体和心理健康相关生活质量。
