“…If the reliability value (đť‘…) < 0.67 is categorized as "poor", 0.67 ≤ đť‘… < 0.80 is categorized as "sufficient", 0.80 ≤ đť‘… ≤ 0.90 is categorized as "good", 0.90 < đť‘… ≤ 0.94 is categorized as "very good", and đť‘… > 0.94 is categorized as "excellent" [34]. The reliability was then proven by a graph of the relationship between information function and SEM obtained from the Parscale program [35]. Meanwhile, the item difficulty index (b) was obtained through analysis of the Quest program.…”

“…El instrumento utilizado se validĂł para la poblaciĂłn mexicana durante el año 2020 mediante la aplicaciĂłn del mĂ©todo Delphi ajustado (Cabero & Infante, 2014;George & Trujillo, 2018;LĂłpez de Arana et al, 2020). Los resultados indicaron la obtenciĂłn de una valoraciĂłn estadĂ­stica para cada Ă­tem superior a 0.80 respecto al coeficiente de validez de contenido (V de Aiken) (Aw, 2019;Hidayati, Budiyono & Sugiman, 2019), y un valor de intervalo de confianza (ICI) mayor a 0.50 (Maxey & Kezar, 2016;Wilcox & Serang, 2017). Durante la validaciĂłn, el análisis cualitativo tuvo como propĂłsito valorar la calidad y claridad de la redacciĂłn de cada Ă­tem e identificar la presencia de sesgos.…”
