Notes: SB Χ² = Satorra-Bentler chi-square; SB ΔΧ² = Satorra-Bentler scaled-difference chi-square; df = degrees of freedom; BIC = Bayesian information criterion; RMSEA = root mean square error of approximation. All models allow for quantitative sex differences. Pathway labels are shown in Figure 1. Model 3 is the full model illustrated in Figure 1. Model 4 is the same full model but dropping a₃₃, which was estimated to be 0. The fits of models 5–7 are compared to Model 4. In Model 5, genetic pathways a₃₂ and a₃₃ were dropped. In Model 6, genetic pathway a₃₃ and environmental pathway c₃₂ were dropped. In Model 7, genetic pathway a₃₃ and environmental pathway e₃₂ were dropped.

^*A Wald test indicates that dropping c32 from the model results in a significant loss in fit.
