“…As Zumbo and Rupp (2004) note, scoring test data eventually brings about consequences for test-takers and these consequences are mathematically dependent upon accurately estimating the error associated with test-takers' scores, which is most crucial for test-takers with an observed score somewhere around the cutscore. It has long been recognized in the statistical theory of psychometrics that the score error is not constant along the continuum of test scores even though in early work in classical test theory unconditional raw-score standard error of measurement was reported and used.…”

“…Para evaluar la consistencia interna de los instrumentos se calcularon dos indicadores: el coeficiente alfa de Cronbach y el coeficiente omega de McDonald (Elosua Oliden & Zumbo, 2008). El primero se calculó por ser el índice más usado en ciencias sociales (Zumbo & Rupp, 2004), lo que permite tener puntos de comparación con otros estudios. El segundo se utilizó porque constituye una de las más recientes alternativas para estimar la consistencia interna, en la medida que considera la naturaleza ordinal de los datos y es más preciso en las estimaciones (Zinbarg, Revelle, Yovel & Li, 2005).…”

“…No obstante, la practicidad que supone su brevedad presenta limitaciones metodológicas como la estimación de la confiabilidad. Para estimar la confiabilidad de los puntajes, el coeficiente α (Cronbach, 1951) es el estimador más usado por los investigadores en psicología (Elosua & Zumbo, 2008;Ledesma, 2002;Zumbo, & Rupp, 2004). Aun con su uso extendido, muchas veces no se conoce si los datos cumplen algunas condiciones requeridas para su aplicación, como por ejemplo, el modelo de medición apropiado.…”
