Richard has developed an intervention that he believes will improve the parenting skills of teenage fathers. He has observers rate the behavior of the fathers when their infants are less than one month old, provides the young men with parenting education, and then has the observers rate the interaction of the fathers and infants again when the babies are about six months old. One of the measures Richard is using is the amount of eye contact maintained between the fathers and infants.
