Abstract:
Caucasian college students who intentionally tanned participated in a brief skin cancer intervention based on protection motivation theory (PMT). This intervention targeted skin appearance and consisted of brief lectures, a comprehensive essay, video clips about a young man who died of melanoma, and short discussions. Compared to a waitlist control group, the intervention group showed increases on PMT variables and intentions at post-test. The waitlist group later received the intervention and showed similar increases. Additionally, all but one PMT variable maintained post-test levels at a one-month follow-up. Photographs taken at post-test and at the one-month follow-up were judged by raters blind to the hypothesis. Seventy-two percent of participants were judged to have lighter skin whereas only 16 percent had darker skin. These results provide additional support for theory-based methods for changing maladaptive attitudes and behaviors associated with skin cancer risk.
