Longitudinal relations among ego‐resiliency ( ER ), effortful control ( EC ), and observed intrusive parenting were examined at 18, 30, and 42 months of age ( N s = 256, 230, and 210) using structural equation modeling. Intrusive parenting at 18 and 30 months negatively predicted EC a year later, over and above earlier levels. EC at 30 months mediated the negative relation between 18‐month intrusive parenting and ER at 42 months when controlling for stability of the variables. ER did not predict EC . The findings suggest that intrusive parenting may have a negative effect on children's ego‐resiliency through its effects on children's abilities to regulate attention and behavior.
