ABSTRACT
An additional series of multiple-group models was tested to determine if the hierarchical model structure of child intelligence was invariant across children who were tested in their homes versus in the laboratory. The tests of metric and scalar invariance at the first-order and second-order levels all indicated good fit, suggesting that the hierarchical g-and-Fs model was fully invariant across children in 0 to 10 and 11 or more hours of childcare. To test whether the hierarchical model of the g-and-Fs structure of child intelligence held while accounting for the variance in child intelligence associated with family socioeconomic status, maternal verbal intelligence, and maternal age, an additional structural equation model was evaluated. All paths from the final g-and-Fs model maintained significance while partialing out the variance associated with Socioeconomic status. This analysis suggests that the structure of child intelligence holds independent of variation in socioeconomic status and maternal verbal intelligence and age.
