We therefore proceeded to examine the AE model separately in MM and FF pairs. To obtain parameter estimates from our two remaining internalizing variables (BiP and SE), we substituted these variables in two separate AE models for E. The parameter estimates of the AE model for all 11 variables in males are given in Table 4. The three variables MD, GAD and N stood out as having loadings in excess of +0.45 on the genetic common factor. Three further variables had more moderate loadings (0.25–0.35): SE, AgP and PD. All the other variables had fairly modest loadings on the genetic common factor (i.e.<+0.20).
