Measurement invariance of the pay satisfaction questionnaire across three countries

In recent years, pay satisfaction has been increasingly studied in an international context, prompting the importance of examining whether the Pay Satisfaction Questionnaire (PSQ) is invariant across countries other than the United States. This study investigated the measurement invariance across three countries, namely, the United States (N = 321), Belgium (N = 301), and Cyprus (N = 132). Results showed that the measurement structure of the PSQ was invariant across these different countries because there was no departure from measurement invariance in terms of factor form, factor pattern coefficients, factor variances, and factor covariances. These results show promise for the equivalence of PSQ ratings across different countries. Future research is needed to test the equivalence further across other countries and samples.
