本文提出将倾向得分调整方法扩展到潜变量模型。倾向评分由 Rosenbaum 和 Rubin (1983) 提出，作为在非随机研究中观察到的协变量平衡治疗组和对照组的一种手段。倾向评分定义为在给定一组观察到的协变量的情况下分配到治疗组的条件概率。在这种方法的典型应用中，每个观察结果都与分配到治疗组的倾向相关。然后将倾向得分的分布分为各层，并在各层内进行治疗组差异的分析。层内和层间治疗组差异的比较提供了证据，表明倾向评分调整是否已解释了由于非随机选择治疗组而产生的偏差。本文将倾向评分方法的应用扩展到潜在变量的群体差异分析。特别是，多样本 MIMIC 模型用于测试有关跨层潜在变量的治疗组差异的假设。还讨论了与本文所提倡的方法相关的阶乘不变性的作用。使用 1988 年国家教育纵向研究（国家教育统计中心，1988）的数据，对自我概念和控制源的学术跟踪差异问题的应用说明了这一过程。
This article proposes an extension of the propensity score adjustment method to latent variable models. The propensity score was proposed by Rosenbaum and Rubin (1983) as a means of balancing treatment and control groups with respect to observed covariates in non-randomized studies. The propensity score is defined as the conditional probability of assignment to a treatment group given a set of observed covariates. In a typical application of this approach, each observation is associated with a propensity to be assigned to the treatment group. The distribution of propensity scores is then divided into strata and analyses of treatment group differences are conducted within strata. Comparisons of treatment group differences within and across strata provide evidence for whether or not the bias due to non-random selection into treatment groups has been accounted for by the propensity score adjustment. This article extends the application of the propensity score approach to the analysis of group differences on latent variables. In particular, multi-sample MIMIC modeling is utilized to test hypotheses about treatment group differences on latent variables across strata. The role of factorial invariance as it relates to the approach advocated in this article is also discussed. An application to the problem of academic tracking differences in self-concept and locus-of-control, using data from the National Educational Longitudinal Study of 1988 (National Center for Education Statistics, 1988), illustrates the procedure.
