1972年秋在美国北卡罗来纳州的达勒姆县抽取了331名65岁及以上的老年人作为样本，用沿着3个参数对他们的社会支持状况进行了评估：角色和可获得的依恋、感知的社会支持和社会交往频率。这种方法来评估社会支持的补充以前的方法来衡量社会支持没有比较的各个组成部分的结构。30个月后确定死亡率状态（结局变量）。经过初步评估后。粗死亡率的相对危险度分别为1.96受损的角色和可用的附件，3.86受损的感知社会支持，和2.72受损的频率的社会互动。10个潜在的混杂变量-年龄，性别，种族，经济状况，身体健康状况，自我照顾能力，抑郁症状，认知功能，压力生活事件，吸烟-采用二元线性回归分析进行控制。当控制变量被纳入回归模型时，受损的角色和可用的附件，受损的感知社会支持和受损的社会互动频率的相对死亡率风险估计分别为2.04，3.40和1.88。因此，这3个参数的社会支持显着预测30个月。在社区老年人样本中进行的粗分析和对照分析中的死亡率。
A community sample made in the fall of 1972 in Durham County, North Carolina, USA, consisted of 331 persons 65 yr of age and older was assessed for adequacy of social support along 3 parameters: roles and available attachments, perceived social support and frequency of social interaction. This approach to the assessment of social support complements previous approaches to the measurement of social support which have not compared the various components of the construct. Mortality status, the outcome variable, was determined 30 mo. after the initial assessment. The crude relative risks of mortality were 1.96 for impaired roles and available attachments, 3.86 for impaired perceived social support, and 2.72 for impaired frequency of social interaction. Ten potential confounding variables-age, sex, race, economic status, physical health status, self-care capacity, depressive symptoms, cognitive functioning, stressful life events, and cigarette smoking-were controlled using binary linear regression analysis. The estimates of relative mortality risk were 2.04, 3.40, and 1.88, respectively, for impaired roles and available attachments, impaired perceived social support, and impaired frequency of social interaction when the control variables were included in a regression model. Therefore, these 3 parameters of social support significantly predicted 30 mo. mortality in both crude and controlled analyses in a community sample of older adults.
