A nationwide random sample of 15,169 Norwegian high school students co
mpleted a questionnaire about tanning habits, physical self-concept, a
ttitudes, beliefs, and values. Although 90% of the adolescents did use
sunscreen, less than 25% used an adequate sun-protection factor, and
only 50% applied the sunscreen an adequate number of times when sunbat
hing. Multiple regression analyses identified these predictors of sunb
athing: opportunity to sunbathe, tender skin, heavy smoking, playing d
own the risk for skin cancer, valuing physical appearance, friends' us
e of sunscreen (girls only), a positive attitude toward having a tan,
favorable physical self-concept, friends' use of sunbeds, and friends'
sunbathing. Sunscreen use was also predicted by opportunity to sunbat
he and skin type. Furthermore, the effects of perceived risk for skin
cancer and peers' use of sunscreen were particularly strong.
