The model-fitting results and squared standardized path coefficients for CD are presented in Table 3. Both full sex-limitation models (Table 3: Full rA and Full rC) fit better than the common effects model and the scalar model. The results of the full sex-limitation models indicated that either the genetic or the shared environmental factors influencing CD were different for males and females. Further, though the magnitude of genetic, shared environmental, and non-shared environmental influences on CD was allowed to differ for males and females in both full sex-limitation models, the proportion of variance in CD accounted for by A, C, and E was quite similar for males and females. The parameter estimates for A, C, and E could be constrained to be proportionally equal across sex in both full models without a resultant deterioration in model fit (Full rA: Δχ2 (2) = 2.13, p = .34; Full rC: Δχ2 (2) = 2.04, p = .36; results not shown in Table 3).
