This study investigates the integrated mediating effects of maternal parenting efficacy and maternal parenting attitudes on the relationship between children's difficult temperament and problematic behaviors. Utilizing a sample of 328 mothers of children aged 3-5 years from across the nation, we measured children's temperament, maternal parenting efficacy, maternal parenting attitudes (PPI), and children's problematic behaviors (K-CBCL 1.5-5). The findings are as follows: First, significant correlations were observed among children's difficult temperament, maternal parenting efficacy, maternal parenting attitudes, and children's problematic behaviors. Second, children's difficult temperament had a statistically significant impact on children's problematic behaviors mediated by maternal parenting attitudes; however, the mediating effect of maternal parenting efficacy on children's problematic behaviors was not statistically significant. Lastly, it was determined that children's difficult temperament indirectly impacted problematic behaviors via a sequential mediation pathway involving maternal parenting efficacy and maternal parenting attitudes. These findings provide fundamental background suggesting the importance of maternal roles as primary caregivers and both internal and external variables in understanding the direct impact of children's difficult temperament on their problematic behaviors. Moreover, the study provides foundational insights for the order of approaches to positively influence maternal parenting practices.
