In this issue of the Journal, Villalonga-Olives et al. (Am J Epidemiol. 2023;192(8):1264-1273) examined the psychometric properties of social capital indicators, comparing responses from Black and White people to identify whether there was differential item functioning (DIF) in social capital by race, and also when stratified by educational attainment, as a measure of socioeconomic status. The authors tested whether there is DIF in social capital items between Black and White people and found that DIF across these items was significant although not large, but they were still indicative of measurement error, which they suspected was related to the way these items were developed-that is, based on cultural assumptions tested in mainstream White America. However, some gaps remain to be fleshed out.
在本期《美国流行病学杂志》中，Villalonga-Olives 等人（Am J Epidemiol. 2023;192(8):1264-1273）研究了社会资本指标的心理测量特性，比较了黑人和白人的反应，以确定社会资本是否存在因种族而异的差异功能（DIF），并在按教育程度分层时，将其作为社会经济地位的衡量标准。作者测试了社会资本项目在黑人和白人之间是否存在 DIF，发现这些项目之间的 DIF 虽然不显著，但仍然具有测量误差的指示性，他们怀疑这与这些项目的开发方式有关，即基于在主流白人美国进行测试的文化假设。然而，仍有一些差距需要填补。
