Attitudes and beliefs of Australian schoolchildren about bullying in s
chools were assessed and related to age, gender and reported involveme
nt in bullying others at school. Questionnaires were answered anonymou
sly by 2940 boys and 2508 girls attending 20 South Australian coeducat
ional schools; student ages ranged from 9 to 18 years. The questionnai
res contained the following reliable multi-item measures: attitudes to
ward bullying; normative pressure experienced by students to bully oth
ers at school; attitudes to victims of bullying; perceived capacity to
bully others; and proneness to bully others at school. Generally, the
mean scores on the attitude/belief measures showed similar age trends
to those indicating engagement in bullying behaviour. With increasing
age, up to about 16 years, both boys and girls reported more engageme
nt in persistent bullying and displayed attitudes and beliefs more sup
portive of bullying. Beyond 16 years, however, both attitudes and beha
viours moderated, as reflected in results showing significant curvilin
ear (quadratic) relationships. Generally, pro bullying attitudes and b
ehaviours were more common among boys. Multiple regression analyses co
nducted separately for boys and girls showed that for both sexes each
of the attitude/belief variables was independently and significantly r
elated to pronensss to bully others; collectively they accounted for m
ore than 30% of variance on this scale. Results on the attitude/belief
measures were compared for two schools for which high and low levels
of bullying were reported. As predicted, the measures individually and
collectively discriminated between the schools. The implications of t
hese results are discussed for strategies and practices to reduce bull
ying in schools.
