Note. Model 1a = the baseline model; Model 1b = model with problematic items removed; Model 2a = multilevel CFA; Model 2b = Model 2a when allowing within factor measurement error correlations of items with comparable item content; Model 3 = configural measurement invariance; Model 4 = metric measurement invariance; Model 5a = scalar measurement invariance; Model 6a = strict measurement invariance. Model 5b and 6b tested partial measurement invariance
