The link between parenting styles and adolescents’ cyberbullying is well-established. However, few studies have examined fathers and mothers’ parenting styles separately, and even fewer have explored the relationship between parenting styles and cyberbullying from the perspective of attitude towards human dignity. Therefore, the current cross-sectional study aimed to investigate whether attitude towards human dignity underlie the associations between parenting styles and cyberbullying among adolescents. 768 adolescents from two different middle schools in China were measured for their perceptions of parenting style, cyberbullying behavior, and attitude towards human dignity. Regression analysis showed that except for paternal overprotection, both the cognition and behavioral tendency of human dignity had a significant indirect effect on fathers’/mothers’ parenting styles and cyberbullying. Still, the emotion of human dignity had no significant indirect effect.
