Objectives In this study, we selected variables that affect human rights-friendly parenting attitudes for parents and analyzed the correlations and moderating effects between them. Methods To do so, we surveyed 400 people, 200 fathers and 200 mothers of young children aged 3, 4, and 5, to measure variables related to human rights-friendly parenting attitudes. Results Human rights-friendly parenting attitudes for parents were positively related to coparenting and childcare-friendly community, and childcare-friendly community had a moderating effect on the relationship between coparenting and human rights-friendly parenting attitudes. Conclusions Higher levels of coparenting are associated with higher levels of human rights-friendly parenting attitudes, but childcare-friendly community may play a moderating role, such that parents with low levels of coparenting but high levels of childcare-friendly community may have more frequent human rights-friendly parenting attitudes than parents with low levels of coparenting but low levels of childcare-friendly community. This study suggests that parenting education programs should address the need for parents to engage in positive coparenting and for the community to view parenting from a parenting-friendly perspective in order to improve parents' human rights-friendly parenting attitudes.
