With the increasing availability of cross-national data, more attention has been given to the issue of comparability. But while a lot of emphasis has been directed to the assessment of measurement invariance, there has been substantially less concern on how measurement error can affect the results of measurement invariance testing. In this study, we show how correction for measurement error can be applied to measurement invariance analysis. We illustrate this using the concept of "Perceived ethnic threat" measured in the European Social Survey Round 3 (2006). The measurement invariance results before and after correction for measurement error are compared. We show that correction for measurement error offers a viable way to ensure that non-invariant parameters are actually caused by differences in the data and not caused by the measurement method.
随着跨国数据的日益普及，人们越来越关注可比性问题。但是，尽管人们非常重视评估测量不变性，但对于测量误差如何影响测量不变性检验的结果，关注的程度要低得多。在这项研究中，我们展示了如何将测量误差修正应用于测量不变性分析。我们使用在欧洲社会调查第三轮（2006 年）中测量的“感知民族威胁”这一概念来说明这一点。比较了测量误差修正前后的测量不变性结果。我们表明，测量误差修正为确保非不变参数实际上是由数据差异引起的，而不是由测量方法引起的，提供了一种可行的方法。
