Abstract

The study examined the extent to which aspects of the home environment play a mediating role in the relation between maternal and child IQ. The procedure of establishing mediation developed by Baron and Kenny was followed using 608 low birthweight, premature infants from eight different sites. Regression analyses indicated that both maternal IQ and Infant/ Toddler HOME scores obtained at 12 months made significant contributions to 3 year child IQ scores. Maternal IQ and Early Childhood HOME scores obtained at 36 months also both made significant contributions to 3 year child IQ scores. There was a significant “indirect” or mediated affect associated with HOME scores at both time points. Structural equation models were used to confirm information developed in the regression analyses. The fit of the model was good for the total sample and for a sample of children and mothers whose IQs were both greater than 70. A stronger indirect effect was noted at three years as compared to one year.
