From: Measurement equivalence of the SF-36 in the canadian multicentre osteoporosis study
Initial configural invariance model for the SF-36. The circles represent the SF-36 physical and mental health latent factors, the rectangles represent measured indicators (i.e., the domains), the lines connecting latent factors to indicators are factor loadings, and the curve connecting the two latent factors represents covariation. Numbers provided are standardized values for female Caucasians and male Caucasians (in parentheses).
