虽然社交网络的健康促进影响已经在一些研究中显示，很少有人注意到流行病学领域内的测量问题。本文的目的是提出一套新的社交网络测量方法，用于老年人的流行病学研究。我们使用验证性因素分析来测试社交网络的多维模型，使用的数据来自一个大型的流行病学研究，社区居住的成年人年龄在65岁及以上（美国）。使用LISREL进行的解释性因素分析表明，我们的模型提供了一个很好的拟合数据后，相关的测量误差进行了几次调整。在此基础上，我们开发了新的四个维度的测量和社交网络的总结指数。我们的新措施和几个感兴趣的社会人口变量之间的二元关系。(C)1997年爱思唯尔科学有限公司
While the health promoting influences of social networks have been shown in a number of studies, little attention has been paid to measurement issues within the field of epidemiology. The purpose of this paper is to propose a new set of measures of social networks for use in epidemiological research on the elderly. We use confirmatory factor analysis to test a multidimensional model of social networks using data from a large epidemiologic study of community-dwelling adults age 65 and over (U.S.A.). Confirmatory factor analysis conducted using LISREL showed that our model provides a good fit to the data after several adjustments for correlated measurement error were introduced. Based on this analysis, we developed new measures of four dimensions and a summary index of social networks. Bivariate relationships between our new measures and several sociodemographic variables of interest are also presented. (C) 1997 Elsevier Science Ltd.
