Objetivo: Comparar dos sistemas de puntuación para un test de fluidez verbal con el Modelo de Escalas de Calificación. Método: Se analizaron datos de 289 participantes, de los cuales 92 habían sido diagnosticados con Parkinson. Las puntuaciones se calcularon con dos sistemas de categorización: un procedimiento convencional y otro basado en percentiles. Resultados: Las puntuaciones Rasch procedentes de percentiles dan lugar a categorías adecuadas y medidas fiables; la correlación con las puntuaciones del test Minimental es evidencia de validez concurrente. Tras controlar estadísticamente el efecto de la edad, las medidas Rasch procedentes de percentiles discriminan entre ambos grupos, lo que evidencia validez predictiva. Conclusiones: El análisis de los dos procedimientos permite recomendar el uso de las categorías basadas en percentiles.
