Szigriszt made adaptation the RES Flesch Score, calling it “Escala de Nivel Perspicuidad” (Clarity Level Scale), to measure difficulty in reading a text. But used text sample that was neither representative nor random, which why conclusions are not sufficiently consistent. aim this article complete process begun by Szigriszt, review Scale, comparing with Flesch’s scale, and propose scale according Spanish habits. Methods. Descriptive study. Two hundred ten documents 3 types were selected random: Stationary magazines, school textbooks scientific magazines. Three fragments least 500 words chosen random from each one, beginning, middle end. Flesch-Szigriszt Index (Indice Legibilidad [IFSZ]), available on INFLESZ program, calculated. scores classified scales. Results. stationary magazines 60, 37.9, 67.39. Conclusions. Only situated between 0 50. There no publications lower than 15. Szigrsizt locates “Normal” 50; 60. An intermediate position adopted new proposed: establishes 5 sections: “Very difficult” ( 80). Neither Clarity Scale Score adapted In case health, there greater probability their being read understood if they exceed 55.
