A random sample of students (N = 3,655) in Grades 7, 9, mid 11 from 55 scho
ols in Queensland (Australia) were surveyed about their sun protection know
ledge, attitudes and behaviors. An aggregate sun protection behavior index
(SPBI) tvas developed from self-reported behaviors on a school day and a we
ekend day. Repeated measures regression analyses revealed that negative vie
ws of sun protection measures were associated with low scores on the SPBI,
an association that was strongest among alder students and in larger school
s. Low perceived parental sun protective behaviors were associated with low
SPBI ratings, and this association was greatest in small schools and on Sa
turdays. Older students had lower SPBI ratings, but their scores increased
art Saturdays. Gender did not appear to be independently related to the SPB
I after adjustment for the other variables. These findings reinforce the ne
ed for adolescent sun protection programs to address the complex interactio
ns among psychological, social, and environmental factors that influence di
fferent subgroups of the student population.
