AbstractThe purpose of this study was to examine factors related to the quality of the home environments mothers provide for their infants. Data from the National Longitudinal Survey of Youth on 602 mothers with infants between 12 and 23 months of age were used for this study. Consistent with Belsky's model of the determinants of parenting, the quality of the home environment was influenced by maternal characteristics, child characteristics, and contextual factors. A positive linear relation was found between scores on a family risk index and the probability that infants were experiencing a relatively unsupportive home environment.
