Does Knowledge Influence Melanoma-Prone Behavior? Awareness, Exposure, and Sun Protection Among Five Social Groups

Abstract

To examine melanoma-related knowledge, sun exposure, and sun protection to determine whether increased awareness is associated with a reduction in risk. Quantitative/empiricist study conducted by purpose- designed mailed questionnaire. Consultant oncologists at one teaching hospital in London, England; specialist registrars (oncologists in training) contacted through a London-based educational group; oncology-trained nursing staff from oncology departments at two London teaching hospitals; medical students; general (nononcology) nurses; and members of the lay public from one London teaching hospital. Two teaching hospitals in London, both registered cancer centers that possess specialist departments of oncology and are staffed by clinical and medical oncologists. Anonymous, self-completion, mailed questionnaire. RESEARCH VARIABLES: Sun exposure; use of sun protection and avoidance; knowledge of the biologic effects of sun exposure, moles, and malignant melanoma; melanoma-prone behavior. No significant differences were found in sun exposure or melanoma-prone behavior across the five groups studied. No correlation existed between knowledge and melanoma-prone behavior. Differences in knowledge and protection scores were demonstrated across all groups and were statistically significant, but they did not translate into changes in exposure or behavior scores. Public health policy that seeks to reduce the incidence of melanoma is based on the false premise that increasing awareness of melanoma risk will reduce melanoma-prone behavior. Increasing awareness of the risks of sun exposure may improve the use of sun protection, but it does not reduce melanoma-prone behavior, even among specialist healthcare professionals. This study provides a new epidemiologic tool for nurses working in the specialty.
