Table 3 Standardized factor loadings for the final two factor model (Model 3) for the SF-12v2 amongst total sample, and subsamples based on questionnaire language

From: Confirmatory factor analysis and measurement invariance of the English, Mandarin, and Malay versions of the SF-12v2 within a representative sample of the multi-ethnic Singapore population

SF-12v2 items Total sample (n = 6113a) Subsamples split by language
English (n = 4914a) Mandarin (n = 557a) Malay (n = 642a)
