The relations among physical functioning, social support, depressive symptoms, and life satisfaction were examined in a national sample of 4,734 adults age 65 and older. Regression analyses were used to examine the relative importance of objective and subjective support measures in understanding the relation between physical impairment and quality of life. Impairment was associated with fewer friendship contacts, fewer family contacts, less perceived belonging support, and less perceived tangible aid, but only measures of perceived support predicted depressive symptomatology. A structural equation modeling approach was then used to explore the mediational role of perceived social support in the relation between impairment and quality of life variables. Results are consistent with the hypothesis that lower reported social support is an important reason for decreases in life satisfaction and increases in depressive symptoms found among older adult populations. Implications for understanding the role of social support in attenuating the effects of physical disability in older adults are discussed.
在一个由4734名65岁及以上成年人组成的全国性样本中，研究了身体机能、社会支持、抑郁症状和生活满意度之间的关系。采用回归分析来检验客观和主观支持措施在理解身体损伤与生活质量关系中的相对重要性。损伤与较少的友谊联系、较少的家庭联系、较少的感知归属感支持和较少的感知实际帮助相关，但只有感知支持的测量指标能预测抑郁症状。然后使用结构方程建模方法来探讨感知社会支持在损伤与生活质量变量关系中的中介作用。结果与以下假设一致，即报告的社会支持较低是老年人群体中生活满意度下降和抑郁症状增加的一个重要原因。讨论了理解社会支持在减轻老年人身体残疾影响方面作用的意义。
