To analyse the empirical support of the functional ability concept in the healthy ageing framework developed by the WHO in a sample of the Philippine older population. According to this framework, environmental factors may enhance or hinder functional ability, which is the person's ability to do what they value, broadly represented by subjective well-being. Moreover, this network of relationships may be moderated by personal characteristics such as gender.
Cross-sectional observational study.
Philippines, general population.
Respondents of the 2016 National Disability Prevalence Survey/Model Functioning Survey aged 50+ (N=2825).
Latent (unobserved) measures of functional ability, environmental factors (physical environmental factors and social network and support) and subjective well-being (positive affect, negative affect and evaluative well-being) were obtained from different items from the survey questionnaire using a SEM framework.
We found that the relationship between environmental factors and the three components of subjective well-being considered in this study was partially explained by differences in functional ability. The portion of those effects accounted for by functional ability was comparatively larger for the physical than for the social environmental factors. We found no evidences of gender differences in this network of relationships.
These findings suggest the relevance of functional ability at explaining the relationship between environmental factors and subjective well-being in older adults. Future studies may replicate these findings longitudinally and including other relevant measures as the person's objective level of intrinsic capacity.
在世界卫生组织（WHO）制定的健康老龄化框架中，分析功能能力概念在菲律宾老年人群体样本中的经验支持。根据该框架，环境因素可以增强或阻碍功能能力，而功能能力是指一个人完成他们认为有价值的事情的能力，这主要由主观幸福感来代表。此外，这种关系网络可能受到个人特征（如性别）的调节。
横断面观察性研究。
菲律宾，一般人群。
2016 年全国残疾患病率调查/模型功能调查中年龄在 50 岁以上的受访者（N=2825）。
使用 SEM 框架，从调查问卷中的不同项目中获得功能能力、环境因素（物理环境因素和社会网络与支持）和主观幸福感（积极情绪、消极情绪和评价幸福感）的潜在（未观察到）测量值。
我们发现，环境因素与本研究中考虑的主观幸福感的三个组成部分之间的关系部分由功能能力的差异解释。功能能力对这些影响的解释比例在物理环境因素方面相对大于社会环境因素。我们没有发现这些关系网络中存在性别差异的证据。
这些发现表明，在解释环境因素与老年人主观幸福感之间的关系时，功能能力具有重要意义。未来的研究可以在纵向和包括其他相关措施方面复制这些发现，如人的内在能力的客观水平。
