The hypothesis that physical aggression in the family affects children's ad
justment through both observational learning/modeling and through its impac
t on parenting was tested (via LISREL) using data from a representative sam
ple of Canadian children (N = 11,221). Results showed that observational le
arning and disrupted parenting provide reasonable, if only partial explanat
ions, of mothers' assessments of children's adjustment in families characte
rized by physical aggression. Models for preschool (4-5 years), young (6-9
years), and older school-age (10-11 years) children fit acceptably and show
ed similar but weak effects, Children reported to witness more aggression a
lso were reported to behave more aggressively. Mothers who reported being l
ess warm and responsive in parenting reported that their children were more
aggressive, had more internalizing behaviors, and had fewer prosocial beha
viors.
