Yet parenting behaviors do not affect all children uniformly and effects may depend on identifiable child characteristics. One factor is a child’s biological sensitivity to the caregiving environment, an indicator of which is a stress hormone, cortisol. This longitudinal study examines two dimensions of observable parenting behaviors, responsive and rejecting/harsh. These parenting behaviors and child cortisol awakening response (CAR) were measured during home visits in a sample of 100 mostly low-income White and Latina/Hispanic mothers and their children at ages 4-6. Children’s internalizing and externalizing behaviors were assessed one year later. We tested the effects of responsive and harsh/rejecting parenting on child internalizing and externalizing and examined child CAR as a moderator. Results indicated that responsive parenting predicted better child mental health as indexed by fewer internalizing and externalizing behaviors, whereas harsh/rejecting parenting predicted more internalizing behaviors. Harsh/rejecting parenting interacted with child CAR such that harsh/rejecting parenting predicted more externalizing only among children with low CAR; there was no interaction of responsive parenting with child CAR. These results elucidate how child CAR may shape mental health outcomes associated with harsh/rejecting parenting.
