Background: Even though skin cancer is a cancer, increasing incidence in whole world, the disease can be prevented by improving protective behaviors across it. However, individuals' attitudes and beliefs about the subject ought to be evaluated to improve skin cancer prevention behaviors of the individuals firstly. Aim of this study was to develop Skin Cancer Scale based on the Health Belief Model in order to assess attitudes and beliefs about skin cancer. Methods: This methodological study included 465 randomly selected university students who educated seven different department of a university. Data were collected with a socio-demographic form and 42 items daft scale of Health Belied Model Scale in Skin Cancer. Experts’ opinions and pre-test were obtained for content validity. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) was performed for construct validity. Cronbach’s alpha internal consistency coefficient and test-retest correlation coefficients were calculated for reliability. Results: The internal consistency reliability coefficient of this scale was 0.86 and the item - total score correlation coefficients changed between 0.32 and 0.66. According to EFA; factor loads ranged from 0.45 to 0.86, the 26-items were divided into five sub-dimensions. To CFA, model fit indexes of the scale were found as x2 / df ratio: 2.391, the Root Mean Square Error of Approximation (RMSEA): 0.055, the Good¬ness of Fit Index (GFI): 0. 901, the Tucker-Lewis İndex (TLI): 0.913 and the Comparative Fit Index (CFI): 0.925. The Cronbach alpha coefficient was 0.87 for the whole scale. Conclusions: The results of the study indicated that The Health Belief Model Scale in Skin Cancer is a reliable and valid scale to measure the attitudes and beliefs about skin cancer.
