Structural model for the Externalizing domain. Figure 3 shows the results of the multivariate analyses for the CBCL subscale factors from the Externalizing domain in the time span between age 18 months and 36 months. All cross-sectional and longitudinal relationships are reported. Double-headed arrows represent correlations, one-sided arrows represent regressions. Coefficients include correlation coefficients and standardized betas. Controlling the initial association between Externalizing behavior problems and BMI, the results show the extent to which Externalizing behavior problems are related with subsequent BMI, and whether BMI is associated with subsequent Externalizing behavior problems (cross-lagged pathways). The associations pertaining to the relationships between the different domains of Externalizing behavior problems and BMI are depicted in larger and bold numbers. All associations are adjusted for the background variables child sex, maternal BMI at child age 18 months, and maternal education.
