Four scales measuring mental wellbeing in the Nordic countries: do they tell the same story?

Table 5 Bifactor modeling* of four scales for the measurement of mental wellbeing (n = 27 364). YX-standardized factor loadings. WLSMV estimator. RMSEA = .031; CFI = .982; TLI = .977. Weighted data. Intercorrelations between all factors (including Cantril’s ladder) restricted to zero

^*In order to obtain good fit, three error terms had to be included in the model: SWEMWBS item 1 with item2 (standardized coeff. = .326); SWEMWBS item3 with WHO item 2 (standardized coeff. = .466), and HBSC items 4 and 5 (standardized coeff. = .288)
