To examine whether a multidimensional social support instrument can be used for comparative research in four diverse ethnic groups of women (African American, Latina, Chinese, non-Latina White). The social support instrument was administered as part of a larger survey to 1,137 women. We tested the reliability and validity of this instrument. A confirmatory factor analytic (CFA) framework was used to test for the invariance of the instrument's psychometric properties across ethnic groups. We used multitrait scaling to eliminate items that did not meet the item-convergence criterion (r > 0.30) and where items were non-convergent items in at least three groups. A series of nested CFA models assessed the level of factorial invariance. One thousand seventy-four women completed the survey; Their mean age was 61 years with Chinese and Latinas reporting lower education compared to non-Latino Whites (p <. 001). A four-factor model (Tangible, Informational, Financial, Emotional/Companionship) fit within each ethnic group separately, suggested good fit. Multi-group CFA supported configural and metric invariance across all ethnic groups. Only partial scalar invariance was supported. This 8-item instrument is a reliable and valid tool that can be used as a multidimensional measure of social support. It can used to examine social support within one ethnic group and for comparative research across diverse ethnic groups of women.
为了检验一种多维社会支持工具是否可用于对四个不同种族的女性群体（非裔美国人、拉丁裔、华裔、非拉丁裔白人）进行比较研究。该社会支持工具作为一项更大规模调查的一部分，施用于1137名女性。我们测试了该工具的信度和效度。使用验证性因素分析（CFA）框架来检验该工具的心理测量特性在不同种族群体间的不变性。我们使用多特质量表法来剔除不符合项目收敛标准（r>0.30）以及在至少三个群体中为非收敛项目的条目。一系列嵌套的CFA模型评估了因素不变性的水平。1074名女性完成了调查；她们的平均年龄为61岁，华裔和拉丁裔女性的受教育程度低于非拉丁裔白人（p< .001）。一个四因素模型（有形的、信息性的、经济的、情感/陪伴）分别在每个种族群体中拟合良好，表明拟合度较好。多组CFA支持所有种族群体间的构型不变性和度量不变性。仅支持部分标量不变性。这个包含8个条目的工具是一个可靠且有效的工具，可作为社会支持的多维测量方法。它可用于研究一个种族群体内部的社会支持情况，也可用于对不同种族的女性群体进行比较研究。
