Punishment has long been a controversial topic in psychology, perhaps partly because its effects are different under different circumstances. This study used retrospective reports from college students to examine the effects of spanking, a common aversive punishment, on self-esteem and perceived fairness of parental discipline, while taking the effects of other parental characteristics into account. No parental characteristic interacted with the slightly negative effect of spanking on self-esteem and fairness. However, controlling for positive communication or for a parent-oriented motivation for spanking eliminated the negative effects of spanking, suggesting that the negative effects reflected use of spanking as a replacement for positive communication with the child.
