This study analyzed data from 668 elementary school children in grades 3 to 6, along with their families, obtained from the 2018 China Family Panel Studies (CFPS). The aim was to examine the impact of accumulated family risk on children’s problem behavior, as well as the mediating roles of self-esteem and self-control. The results indicated that: (1) Accumulated family risk was significantly positively correlated with children’s problem behavior and significantly negatively correlated with self-esteem and self-control. Furthermore, self-esteem and self-control were both significantly negatively correlated with problem behavior. (2) Both the direct and indirect effects of accumulated family risk on children’s problem behavior were significant. The indirect effects included three pathways: the separate mediating effect of self-esteem, the separate mediating effect of self-control, and the chain mediating effect involving both selfesteem and self-control.
