A model of the association between adolescents' perception of the quality o
f parent/adolescent attachment and adolescent aggression,vas examined with
social cognition and self-esteem as mediators. A total of 68 sixth graders,
their parents, and their language arts teachers participated. Adolescents
completed measures of attachment with mother and with father; self-esteem,
social cognition, and aggressive tendencies. Mothers, fathers, and teachers
each completed measures of adolescent aggressive and prosocial behavior. E
vidence was obtained for social cognition and self-esteem both as mediators
between adolescents' perceived quality of mother/adolescent attachment and
adolescent self-report of aggression. Controlling for mother/adolescent an
d father/adolescent attachment and adolescent self-esteem, adolescent highe
r social cognition was associated with adolescent lower self-report of aggr
ession. Controlling mother/adolescent and father/adolescent attachment and
adolescent social cognition, adolescent higher self-esteem was associated w
ith father-reported lo,ver adolescent aggression and father-reported higher
adolescent prosocial behavior: Implications for further research are discu
ssed.
