Abstract

Skin cancer develops due to the uncontrolled division of skin cells. Although the incidence of skin cancer in Asian countries, including Vietnam, is relatively low, the tropical climate and frequent long-term exposure to ultraviolet radiation (UVR) make sun protection still extremely necessary and urgent. Currently, there is no reliable scale in Vietnam to evaluate skin exposure and protection habits against sunlight. Standardize the Vietnamese version and evaluate the reliability of the Sun Exposure and Protection Index (SEPI) scale.  Our study was conducted from October 2024 to December 2024 on 47 students at Hanoi Medical University, followed by a second survey two weeks later. The results were used to measure internal consistency using Cronbach’s alpha coefficient and test-retest reliability through the Intra-Class Correlation (ICC). The Vietnamese version of the SEPI questionnaire demonstrated high internal consistency with a Cronbach's alpha coefficient of 0.755. The test-retest reliability between the two responses to the questionnaire was very high with an ICC value of 0.927. The study indicates that the Vietnamese version of the SEPI scale is a valid tool for assessing sun exposure and skin protection habits in the Vietnamese population.
