Internal consistency was assessed by calculating the Cronbach alpha coefficient for the entire scale and when each item was removed, as well as through the corrected item-total correlation by means of the Pearson's r test.
La consistencia interna se evaluó calculando el coeficiente alfa de Cronbach para toda la escala y cuando cada ítem era eliminado, así como mediante la correlación ítem-total corregida a través de la prueba r de Pearson.
