Partnership Instability and Child Well-being

Abstract

We use data from three waves of the Fragile Families Study (N = 2,111) to examine the prevalence and effects of mothers’ partnership changes between birth and age 3 on children’s behavior. We find that children born to unmarried and minority parents experience significantly more partnership changes than children born to parents who are married or White. Each transition is associated with a modest increase in behavioral problems, but a significant number of children experience three or more transitions. The effects of instability do not depend on the mothers’ relationship status or race/ethnicity with one exception: instability has a stronger effect on aggression among Hispanic children. The association between instability and behavior is mediated by maternal stress and lower quality mothering.
