Note: N = 381. χ2 = Chi square; df= degrees of freedom; PGFI= parsimony goodness-of-fit; CFI = comparative fit index; RMSEA = root mean square error of approximation.

a = no constraints; b = factor loadings (item regression weights) constrained equal; c = factor loadings and factor covariances constrained; d=factor loadings, covariances and variances constrained; + = post hoc analysis
