Despite the existing restriction of corporal punishment in Croatia, this parental behavior is still present as are positive attitudes about it. Knowing the factors associated with attitudes about the usage of corporal punishment of children can contribute to creating preventive programs, and ultimately result in the reduction of corporal punishment of children. This study aimed to examine differences in attitudes based on gender in the justification of corporal punishment of children and determine how the experience of corporal punishment in childhood, type of educational program in colleges and knowledge of corporal punishment restriction in Croatia are related to these differences. A total of 215 female and 86 male students from Croatia participated in the research and filled out the Subscale of beliefs about the justification of corporal punishment. The Subscale was available online. Two-way analyses of variance showed that there were statistically significant gender differences in justification of corporal punishment of children and that those differences are related to the experience of corporal punishment in childhood and type of educational program in colleges. Male students justified the usage of corporal punishment of children more than female students. Furthermore, male students who had experienced corporal punishment during their childhood and those who did not attend educational programs in their colleges which include topics about child development and rearing were more prone to justification, than the remaining participants (female students, and male students who did not experience corporal punishment in childhood, as well as male students who attended colleges where educational programs include topics on child development and rearing). These results suggest that programs which aim to encourage development of negative attitudes about corporal punishment of children (and subsequently reduce the use of this type of behavior in child rearing) need to be more focused towards men’s attitudes.
