Resumen
Se discuten las limitaciones de dos procedimientos de medición extremadamente populares; la escala Likert y los diseños pre-post tradicionales. Ambos métodos tienen limitaciones; estos métodos son comúnmente combinados obteniendo como resultado una fidelidad limitada para la medición del cambio. Se discute sobre dos innovaciones en medición que proveen al investigador una mayor fidelidad: escalas visuales análogas y el diseño pre-test retrospectivo. Además, cuando se usan de manera combinada, estas innovaciones en medición proveen notables incrementos en el poder de detección y la cuantificación de cambios.
