Objectives. This feasibility study examined whether a sun safety curri
culum designed for and administered to preschoolers affects their cogn
ition (knowledge, comprehension, application) regarding sun safety. Me
thods. Twelve classes of 4- to 5-year-olds were recruited from local p
reschools and randomly assigned to an intervention group or a central
group. The intervention group received an investigator-developed sun s
afety curriculum; the control group did not. Children in both groups w
ere tested at the beginning of the study about their cognition related
to sun safety. They then received posttests 2 and 7 weeks following t
he pretest. Results. The curriculum had a significant effect on the kn
owledge (P = .01) and comprehension (P = .006) components of cognition
. The application component of cognition was not significantly changed
by the curriculum. Conclusions. A structured curriculum was found to
be an efficacious means of enhancing knowledge and comprehension of su
n safety in preschool children. At the preoperational developmental st
age, however, children may not be able to apply such knowledge and com
prehension.
