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.
