i
For the WRRMP Wave 4 data we use the same configuration of items as the remaining datasets for the two factor models, notwithstanding the better fit of the alternative model. Interestingly correlations remained non-significant with the alternative item configuration reported in Johnson et al. (2008).
ii
SES proxy variable comprising an average of both parents’ educational attainment.
iii
English and math assessments at age 7.
