We examined the fit of an AE independent pathway model with nine a priori internalizing disorders and traits assessed in both males and females (MD, GAD, PD, AgP, SoP, SiP, AnP, N and E). The fit of an AE model assuming separate parameters in males and females (AIC= −41317.2) was substantially better than that of a CE model (AIC= −41240.6), and also better than that of an AE model that forces all the parameters to be the same in males and females (AIC= −41314.1).
