Note.

1

All models were estimated using WLSMV in Mplus. No cross-loadings and measurement error covariances were specified in the models.

2

The residual variance of factor Agitation was fixed to 0 to avoid a negative residual variance in model estimation.

CFI: Comparative fit index.

TLI: Tucker-Lewis index.

RMSEA: Root mean square error of approximation.

WRMR: Weighted root mean square residual.
