Model 1: Configural invariance	.12 [.12, .12]	.91	.05
Model 2: Metric invariance	.11 [.11, .12]	.90	.99

CONFIGURAL INVARIANCE = This model places no equality constraints across groups on factor loadings, the error variances, the variances of the latent variables, or the covariances of the latent variables
METRIC INVARIACNE = This model places the factor loadings to be equal across groups
STRONG INVARIANCE = This model constrains item loadings, error-variances of the items, variances
RMSEA Root mean square error of approximation, CFI Comparative fit index, SRMR Standard root mean square residual
