Abstract
espanolIntroduccion. Cuando con los resultados de un examen clinico objetivo estructurado (ECOE) se decide sobre la futura competencia profesional de estudiantes de medicina, la fiabilidad de dicha prueba debe adecuarse a esta finalidad. Objetivo. Calcular la fiabilidad (alfa de Cronbach) de una serie de ECOE y su relacion con la duracion, numero de participantes, estaciones, items y evaluadores. Sujetos y metodos. Se analizan 14 ECOE realizados a 2.995 estudiantes de cuarto y quinto curso de la Facultad de Medicina de Granada desde 2004 a 2013. Resultados. La fiabilidad fue ≥ 0,70 en el 92,84% de los ECOE.
