SKIN CANCER PREVENTION
AbstractThe purpose of this project is to develop and evaluate strategies for the
primary prevention of skin cancer. Skin cancers are the most common
cancers today. Primary prevention, aimed at reducing unprotected sun
exposure, is the best way to curb the rising skin cancer incidence rates.
Most importantly, epidemiological evidence suggests that prevention
efforts should focus on children and adolescents. This proposal contains
two studies. The primary aim of study 1, "Skin Cancer Prevention for
Adolescents," is to develop and evaluate the efficacy of an intervention
that uses motivation and efficacy building strategies to increase the sun
protection practices of high school students. Ten high schools with
primarily a white student population will be randomly assigned to one of
two conditions. The Basic Condition will employ an informational based
classroom intervention. The Enhanced Condition will add components to
the Basic intervention that are designed to influence more specifically
motivation, perceptions of social norms favoring sun protection, and
efficacy for using protection. We hypothesize that adolescents in the
Enhanced condition, as compared to the Basic, will report more favorable
attitudes toward sun protection and will show greater increases in
measures of protection: use of sunscreen, protective clothing (hats), and
shade. We will have multiple indicators of behavior change, including
self-reports and requests for sunscreen and hats. Effects of the
intervention will be measured over two summers. The overall aim of study
2," Skin Cancer Prevention Intervention with Day Care Providers," is to
increase the suns protection practices of children's caregivers. Day
care providers play an increasingly important role in our society, not
only in caring for children, but also as serving as informational
resources for parents. The primary aim of study 2 is to develop and
evaluate a multi-component intervention for day care providers that is
based on motivation and compliance enhancement strategies. Twenty-four
day care centers will be matched on center characteristics and then
randomly assigned to one of two conditions: Basic (information only) an
Enhanced (motivation and compliance building). We hypothesize that
caregivers in the Enhanced condition, as compared to the Basic, will more
frequently advise parents about the need to use sun protection with their
children and more frequently use sun protection for children under their
care. Secondary aims include examining the effects of the intervention
on the day care providers use of sun protection for themselves, and
examining the role of organizational and psychosocial factors in
providers' protection practices. We will have multiple measures of
provider behavior including self-report, parent report, and behavioral
observations.
