This study was conducted to examine the effect of corporal punishment on antisocial behavior of children using stronger statistical controls than earlier literature in this area; to examine whether the effect of corporal punishment on antisocial behavior is nonlinear; and to investigate whether the effects of corporal punishment on antisocial behavior differ across racial and ethnic groups. The author used a nonexperimental design and data from the National Longitudinal Survey of Youth. The analysis was conducted using fixed-effects methods to control for observed independent variables and unobserved time-invariant variables. Corporal punishment had a nontrivial effect on children's antisocial behavior in later years despite the strong controls introduced by the fixed-effects models. The analysis provides no evidence for differences in the effect of corporal punishment across racial and ethnic groups.
