OBJECTIVE: The spillover hypothesis suggests that childhood aggression results
from spillover of interparental conflict to poor parenting, which promotes
aggressive child behavior. This study was designed to examine the spillover
hypothesis in non-genetically related parent-child dyads from the toddler period
through age 6 years. METHOD: A sample of 361 sets of children, adoptive parents,
and birth parents from the Early Growth and Development Study (EGDS) was assessed
from child age 9 months to 6 years on measures of adoptive parent financial
strain, antisocial traits, marital hostility, hostile parenting, and child
aggression. Structural equation modeling was used to examine links from financial
strain, parent antisocial traits, and marital hostility in infancy and
toddlerhood to hostile parenting and child aggression at ages 4.5 and 6 years.
RESULTS: Spillover of marital conflict from child age 18 to 27 months was
associated with more parental hostility in mothers and fathers at 27 months. In
turn, adoptive fathers' parental hostility, but not mothers', was associated with
aggression in children at age 4.5 years. However, there was no significant
spillover from hostile parenting at 4.5 years to child aggression at 6 years.
Birth mother antisocial traits were unassociated with child aggression.
CONCLUSION: This study is the first to examine spillover of marital hostility to
parenting to child aggression from toddlerhood through age 6 years in an adoption
design, highlighting the impact of these environmental factors from the toddler
to preschool period. The findings support the potential benefit of early
identification of marital hostility.
