This study examined aggression and withdrawal as predictors of peer victimi
zation. In addition, peer rejection was evaluated as both a moderator and m
ediator of these relations. The sample consisted of 1956 African-American,
Hispanic, and White elementary school-aged boys and girls attending urban a
nd inner-city schools that were classified as high or moderate disadvantage
. Correlation and regression analyses revealed that aggresion predicted bot
h contemporaneous and longitudinal victimization by peers. This relation ma
intained across school disadvantage, ethnicity, age, and sex, and was media
ted by rejection. Withdrawal, mediated by rejection, predicted victimizatio
n for fourth graders only; withdrawal also reduced risk for victimization f
or low rejected children. The implications for understanding the dynamics o
f childhood victimization and intervention are discussed.
