Previous research shows that limitations in activities of daily living (ADLs) are related to greater psychological distress. This study uses a synthesis of life course and stress process perspectives to examine how social support resources and the timing of limitations intersect to shape the relationship between ADL limitations and changes in psychological distress.
Data are derived from a longitudinal study of adults aged 65 and older in the Washington, DC, metropolitan area over a 2-year period (2001-2003).
ADL limitations are positively related to change in depressive symptoms. This relationship is weakened for older individuals, but only at higher levels of perceived social support.
The contribution of this research is to offer a more nuanced view of the mental health consequences of physical limitations in late life by demonstrating that perceived social support provides an important context for age-variegated associations between ADL limitations and changes in psychological distress.
以往的研究表明，日常生活活动（ADL）的限制与更大的心理困扰有关。本研究综合了生命历程和压力过程的观点，探讨了社会支持资源的局限性以及时间的交叉如何影响 ADL 限制与心理困扰变化之间的关系。
数据来自于 2001-2003 年期间华盛顿特区大都市区 65 岁及以上成年人的一项纵向研究。
ADL 限制与抑郁症状的变化呈正相关。这种关系在年龄较大的个体中较弱，但仅在感知社会支持水平较高时才如此。
本研究的贡献在于，通过证明感知社会支持为 ADL 限制与心理困扰变化之间的年龄差异关联提供了重要背景，从而提供了一种更细致入微的视角来看待晚年身体限制对心理健康的影响。
