Resumen
Objetivo: Validar la escala de somnolencia de Karolinska. Métodos: Se tomaron individuos que asistieron a laboratorios de sueño para toma de polisomnografía y personas de la población general. El proceso fue en 6 fases: traducción y retrotraducción del idioma original, validación de apariencia (n=13), prueba piloto (n=20), validez de criterio (n=139) con polisomnografía y la escala de somnolencia de Epworth, reproducibilidad (n=34) y sensibilidad al cambio (n=40). Resultados: La escala de somnolencia de Karolinska tiene una correlación para la validez discriminante con la escala de somnolencia de Epworth dada por un Mann-Whitney z= -2.661 (p= 0.0078); una reproducibilidad aceptable por un Spearman´s Rho= 0.55 (p= 0.0002) y una sensibilidad al cambio dada por un two-side t test con una p= 0.0000. Conclusiones: La escala de somnolencia de Karolinska esta adaptada al lenguaje y condiciones de la población adulta colombiana, lo que constituye una herramienta válida, confiable y fácil de aplicar para la evaluación de los pacientes con hipersomnio.
Abstract Objective: To validate the Karolinska Sleepiness Scale. Methods: Individuals who attended sleep laboratory for a polysomnography study and people in the general population were taken. The process was in 6 phases: translation and back translation of the original language, validating appearance (n = 13), pilot test (n = 20), criterion validity (n = 139) with polysomnography and Epworth sleepiness scale, reproducibility (n = 34) and sensitivity to change (n = 40). Results: Karolinska Sleepiness Scale is correlated to the discriminant validity with the Epworth sleepiness scale given by a Mann-Whitney z = 2661 (p = 0.0078); acceptable reproducibility for Searman's Rho = 0.55 (p = 0.0002) and sensitivity to change given by a two-side t test with p = 0.0000. Conclusions: Karolinska Sleepiness Scale is adapted to the language and conditions of the Colombian adult population, which is a valid, reliable and easy to apply for the evaluation of patients with hypersomnia.
