%X Measurement of information disclosed by companies is a complex task. Accounting research usually relies on disclosure indices to obtain a proxy for the information disclosed by companies. However, there is no consensus about the best design for these indices. The purpose of this paper is to investigate if there are significant differences among the indices that are used in disclosure studies. Three indices that measure disclosure of forward-looking information are compared: A ※quality index§ of a multidimensional nature; a ※scope index§ designed specifically to measure the scope of information, and a ※quantity index§ that measures information disclosed exclusively in terms of quantity. Results of the empirical analysis indicate that although the indices are correlated, they have a big impact in the rankings of companies. Evidence against the idea of the irrelevance of the particular index chosen is provided.La medici車n de la informaci車n divulgada por las empresas es una tarea compleja. La investigaci車n contable normalmente se apoya en 赤ndices de revelaci車n para obtener una aproximaci車n cuantitativa a la informaci車n divulgada por las compa 赤as. Sin embargo, no hay consenso sobre el dise o de estos 赤ndices. El objetivo del trabajo es investigar si hay diferencias significativas entre los 赤ndices empleados en los estudios sobre divulgaci車n de informaci車n. Se comparan tres 赤ndices que miden la revelaci車n de informaci車n previsional: un 赤ndice de calidad, de naturaleza multidimensional; un 赤ndice de alcance, dise ado espec赤ficamente para medir la cobertura de la informaci車n; y un 赤ndice de cantidad que mide la informaci車n divulgada exclusivamente en t谷rminos de cantidad. Los resultados del an芍lisis emp赤rico indican que aunque los 赤ndices est芍n correlacionados, tienen un gran impacto en los rankings de las compa 赤as. El an芍lisis proporciona evidencia en contra de la irrelevancia del dise o de un 赤ndice en particular.
