Model fit indices for the two second-order models to test measurement invariance across the three samples.

German version sample: N = 2,242; French version sample: N = 386; English version sample: N = 306. Configural model: first- and second-order factor loadings were allowed to vary across groups. Metric invariance model: first- and second-order factor loadings were constrained to be equal across groups. Scalar invariance model: first- and second-order factor loadings and intercepts of the indicators were constrained to be equal across groups.
