B2. + Intercepts	883.3	361	0.974	0.043	0.071
Panel C: structural invariance, latent variate scales fixed across groups
C1. Variances: all constrained to unit	898.0	389	0.975	0.041	0.079
C2. Variances: general released, specific constrained to unit	921.6	382	0.973	0.043	0.072
C3. Means: general and specific constrained to zero	1456.9	410	0.948	0.057	0.072

Note: All models are estimated using unweighted least squares estimator with mean and variance adjusted test statistics. Models use delta parameterization. χ², chi-squared test statistics; df, degrees of freedom; CFI, comparative fit index; RMSEA, root mean square error of approximation; SRMR, standardized root mean square residual.
