IntroductionThe Skin Cancer Index (SCI) is the first specific patient-reported outcome measure for patients with cervicofacial nonmelanoma skin cancer. To date, only the original English version has been published.
ObjectivesTo develop a Spanish version of the SCI that is semantically and linguistically equivalent to the original, and to evaluate its measurement properties in this different cultural environment.
Material and methodsA cross-sectional study was conducted of the cultural adaptation and empirical validation of the questionnaire, analysing the psychometric properties of the new index at different stages.
ResultsOf 440 patients recruited to the study, 431 (95%) completed the Spanish version of the SCI questionnaire, in a mean time of 63min (SD 29). Factor analysis of the scale revealed commonality and loading values of <05 for three of the 15 items. The remaining 12 items converged into two components: appearance/social aspects (seven items) and emotional aspects (five items). Both domains presented a high level of internal consistency, with Cronbach's alpha values above 08. The convergent-discriminant validity analysis produced correlations higher than 03 for the mental component of the Short Form Health Survey-12v2 Health Questionnaire (correlation coefficient 039) and the Dermatology Quality of Life Index (correlation coefficient -030). In the test-retest, nine of the 12 items produced a weighted kappa value exceeding 04, and for the remaining three items, the absolute agreement percentage exceeded 60%.
ConclusionsThe Spanish version of the SCI quality of life scale has been satisfactorily adapted and validated for use in Spanish-speaking countries and populations.
