SES= socioeconomic status; b=unstandardized regression coefficient; SE= standard error. Model fit statistics χ² (1, N=564) = 0.356, p=0.551; RMSEA= 0.000 (90% CI=0.000, 0.093); CFI=1.0; SRMR=0.005. Sex was included as a covariate to account for potential sex differences in executive function, bsex, set-shifting = −1.920, SE_{b-sex, set-shifting} = .666 b_{sex, inhibitory control} = −.639, SE_{b-inhibitory control} = .514.
