Gershoff's research focuses on the impact of parental discipline on child and youth development, while taking account of differences in background factors such as poverty, culture, school, and neighborhood. She also examines the effect of exposure to violence on child and youth development, and the efficacy of early childhood and parental educational programs. In 2016, Gershoff and her colleagues published the results of a
meta-analysis of the effects of corporal punishment and physical abuse on children. The studies included in the meta-analysis involved more than 160,000 children and spanned over a 50-year period. The results provided clear evidence in support of the view that spanking children is harmful. The more children were spanked, the more likely they were to experience anti-social behavior, aggression, mental health problems, and cognitive difficulties. The effects of spanking were indistinguishable from the effects of physical abuse on child development outcomes. Gershoff has argued that corporal punishment as a form of discipline fails to teach children why their behavior was wrong nor does it teach them what the appropriate behavior should have been. Parental use of physical punishment teaches children that violence is morally acceptable, causes fear to develop between the child and parent, and subsequently damages their relationship. She estimates that 80% of American children have received physical punishment from their parents by the time they reach the 5th grade and over 70% of parents agree or strongly agree with the sentiment that “children sometimes need a good, hard spanking”. Parents believe in the efficacy of corporal punishment in the absence of any valid evidence that spanking is necessary or effective at correcting misbehavior, regardless the age of the child. Other research provides evidence of intergenerational transmission of violence: individuals who received physical punishment as children are more likely to use physical punishment as adults when disciplining children. == Representative Publications ==
