This study aimed to examine the differences in the justification of corporal punishment of children based on sex and value determinants and determine how the experience of corporal punishment in childhood is related to these differences. The research was conducted online on a sample of 582 students from Croatia composed of an equal number of men and women. To explore justification of corporal punishment Short Situation Scale of Attitude Towards Corporal Punishment was constructed, which contains a description of a specific event while the Presentation of Personal Values was used as a measure of personal values. A complex analysis of variance found that there were statistically significant differences in the justification of corporal punishment of children about the sex of the observer, the sex of the parents and the sex of the child. Men justify corporal punishment more than women and it is most justified in a situation where a mother punishes her son. Corporal punishment in childhood is significantly associated with these differences. Students who experienced corporal punishment in childhood are more prone to justification. Also, a low score on the scale of universalism and a high score on the scale of tradition, power and hedonism are associated with a more pronounced tendency to justify corporal punishment of children.
