Challenges in Multilevel Modelling: Cross-Group Measurement Noninvariance and Measurement Errors. A Monte Carlo Simulation Study
Abstract
Multilevel modelling (MM) is widely utilized in the social sciences, with over 20% of articles in leading sociological journals employing this technique. Despite its prevalence, few studies address whether the variables used in MM are invariant across groups or allow to construct reliable indicators. This study investigates the effects of both measurement noninvariance and random measurement error on MM using Monte Carlo simulations. Our findings reveal significant biases in MM results when random measurement errors are overlooked. Attaining high reliability in the indicators – above 0.94 – can mitigate these biases. While measurement noninvariance introduces bias in MM, its impact is smaller compared to that of the bias caused by unaddressed measurement error. Multilevel structural equation modelling (SEM), which controls for random measurement errors, performs effectively in complete measurement invariance (MI) scenarios. However, the absence of MI can create significant challenges. While multilevel SEM is a powerful analytical tool, it is not immune to the effects of MI assumption violations.
