This research examined sex differences in the factorial structure of the Philadelphia Geriatric Center Morale Scale. In particular, we view the covariance structure of the scale items as a function of several parameter matrices. We analyzed the factorial invariance by testing hypotheses involving the equivalence constraints of one or more parameter matrices in the male and female populations. D...

The aim of this study was to estimate the reliability, validity and factorial invariance of the Portuguese version of the Geriatric/General Oral Health Assessment Index (GOHAI) as applied to Brazilian women.
