Our purpose was to examine the beliefs of college students about UV exposure and sunscreen use and their associations with skin cancer risk and protective behaviors in a cloudy climate. The sample was online survey participants (N = 334) recruited from a large university in Oregon. After fitting an initial measurement model, we fit a structural equation model including Health Beliefs About UV (HBAU) subscales (Health Benefits of Tanning, Seasonal Effects, Tanning Through the Winter, and Sunscreen Toxicity), outcome variables (sunscreen use, indoor tanning, and outdoor tanning), and covariates (eg, tanning and sunscreen use). A minority of participants held the beliefs represented by 3 HBAU subscales, but beliefs about negative health effects of the local weather (Tanning Through the Winter) were common. The measurement and adjusted models provided good fit to the data (χ2 = 143.30; P = .29; df = 136; Root-Mean Square Error of Approximation = .014; Comparative Fit Index = .992; Tucker-Lewis Index = .981). After adjusting for covariates, Sunscreen Toxicity predicted reduced sunscreen use (β = -.12, P = .021), Health Benefits of Tanning predicted outdoor tanning (β = .43, P < .001), and Tanning Through the Winter predicted indoor tanning (β = .31, P = .02). The small sample size, nonresponse rate, and cross-sectional nature of this study mean these findings should be interpreted cautiously. Beliefs about health benefits of sun exposure, the regional weather, and sunscreen safety play a role in skin cancer risk and protective behaviors.
