Note. CFI = comparative fit index; RMSEA = root mean square error of approximation; BIC = Bayesian information criteria; df = degrees of freedom. The best fitting model is highlighted in bold; it was not identical to the final scalar invariance model. Where invariance held, the initial and final model fit was identical. “Initial” model refers to the initial test of invariance, where parameters were fixed over time. “Final” model refers to the final invariance model, with some parameters (see text) freed over time.
