Abstract
Measurement invariance (MI) has received increasing attention in the psychology and organizational management literatures with warnings about the peril of assuming psychometric equivalence (i.e., invariance) of a measure of a latent construct across different conditions (such as time periods) or groups (such as in cross-cultural comparisons) rather than testing for it. Heeding this warning, we offer a beginner’s introduction to MI and assess the MI paradigm in hospitality research by examining studies in the International Journal of Hospitality Management and the Journal of Hospitality and Tourism Education that are susceptible to MI issues. We go further, including a didactic example, humbly examining our own published work on intrapersonal longitudinal change in cultural intelligence and demonstrating how assuming rather than testing for MI led to flawed inferences. Suggestions for researchers wanting to test for MI are provided, as are suggestions for how to proceed when measures are non-invariant.
