Model 1 (No Sex Differences)	858.66	282	113544	.068
Model 2 (Scalar Sex Differences)	574.71	279	113115	.049	100.73	3	<.0001
Model 3 (Quantitative Sex Differences)	567.84	264	113189	.051	18.9	15	n.s.

Notes: SB Χ² = Satorra-Bentler chi-square; SB ΔΧ² = Satorra-Bentler scaled-difference Χ²; df = degrees of freedom; BIC = Bayesian information criterion; RMSEA = root mean square error of approximation. Model 1 (No Sex Differences) constrained all parameters to be equal between sexes. Model 2 (Scalar Sex Differences) constrained all parameters to be equal between sexes, but allowed the total variation/covariation in males to be a scalar multiple of the total variation/covariation in females. Model 3 (Quantitative Sex Differences) allows quantitative sex differences in the structure of genetic and environmental influences. The Satorra-Bentler scaled-difference Χ² is based on a comparison of each model with the model above it.
