Resumen

El Análisis Factorial Exploratorio es una de las técnicas más usadas en el desarrollo, validación y adaptación de instrumentos de medida psicológicos. Su uso se extendió durante los años 60 y ha ido creciendo de forma exponencial al ritmo que el avance de la informática ha permitido. Los criterios empleados en su uso, como es natural, también han evolucio-nado. Pero los investigadores interesados en asuntos sustantivos que utili-zan rutinariamente esta técnica permanecen en muchos casos ignorantes de todo ello. En las últimas décadas numerosos trabajos han denunciado esta situación. La necesidad de actualizar los criterios clásicos para incorporar aquellos más adecuados es una necesidad urgente para hacer investigación de calidad. En este trabajo se revisan los criterios clásicos y, según el caso, se sustituyen o se complementan con otros más actuales. El objetivo es ofrecer al investigador aplicado interesado una guía actualizada acerca de cómo realizar un Análisis Factorial Exploratorio consonante con la psico-metría post-Little Jiffy. Esta revisión y la guía con las recomendaciones co-rrespondientes se han articulado en cuatro grandes bloques: 1) el tipo de datos y la matriz de asociación, 2) el método de estimación de factores, 3) el número de factores a retener, y 4) el método de rotación y asignación de ítems. Al final del artículo hemos incluido una versión breve de la guía
