Examined roles for attitudes about violence as a possible influence on the
frequency of commonplace aggression toward peers among 1,033 adolescents in
the 7th through 9th grades. The peer victimization measure adapted from pr
ior studies yielded 2 reliable subscales: Victimization of Self and Victimi
zation of Others. The attitudes and beliefs measure modified for this study
yielded 3 reliable subscales (Aggression Irs Legitimate and Warranted, Agg
ression Enhances Power and Esteem, One Should Not Intervene in Fights). The
se attitudes were meaningfully related to self-reported aggression toward p
eers but less clearly related to self-victimization. The attitudes were pla
usible mediators of the relation between gender and aggression toward other
s and appeared influential for bath boys' and girls' aggression toward peer
s. Little support was found for these attitudes moderating the relation bet
ween self-victimization and aggression toward others, yet a clear link betw
een victimization of self and aggression toward others was evident. Results
support an emphasis on attitudes and values regarding aggression in violen
ce-prevention efforts, as well as direct efforts to reduce self-victimizati
on.
