The chain mediating role of parenting stress and child maltreatment in the association between maternal adverse childhood experiences and executive functions in preschool children: a longitudinal study.

Background: Previous researches found that maternal adverse childhood experiences not only affect the psychological behavior of preschool children, but also have direct or indirect negative effects on the executive functions and cognition of offspring. And, the possible social psychological mechanism between maternal adverse childhood experiences and preschool children's executive functions is still not clear.

Objectives: This study mainly tries to understand the association between parenting stress and child maltreatment in maternal adverse childhood experiences and children's executive functions through longitudinal cohort.
