  1. *** p < .001, ** p < .01, * p < .05, + p < .10. The “Full” column presents results of the path analysis covarying for dummy-coded maternal race/ethnicity (referent group = Black), child sex, child age, and low child birthweight on each construct at each timepoint. RMSEA = 0.05 [90% CI, 0.05, 0.06], CFI = 0.91, SRMR = 0.04. Path analyses stratified by child sex are presented under the “Female” and “Male” columns. This model allowed paths to freely vary between child sex and covaried for dummy-coded maternal race/ethnicity, child age, and low child birthweight. RMSEA = 0.05 [90% CI 0.04, 0.05], CFI = 0.93, SRMR = 0.04
