Diseño de un nuevo test de agudeza visual en lectura en lengua española: pre-estudio de desarrollo

Abstract

Propòsit: el propòsit d’aquest pre-estudi es construir un test en lectura mitjançant frases de igual elegibilitat, amb la finalitat de mesurar la velocitat lectora (VL) i la agudesa visual lectora (AVL) utilitzant dispositius electrònics. Mètode: 55 frases van ser estadísticament seleccionades de les 70 inicialment desenvolupades. Cada frase te una mitja de 60 caràcters i 11 paraules. Les frases van ser presentades amb un iPad i la lectura oral va ser gravada mitjançant un programa de gravació digital. La AVL va ser mesurada mitjançant frase simples de mida variable. La (VL) va ser mesurada binocular i als subjectes se’ls va demanar que llegissin en veu alta el més ràpidament possible. El temps de lectura va ser calculat, i tenint en compte el errors comesos, la VL en paraules per minut (PPM) va ser calculada. La variabilitat de la VL y la AVL entre subjectes i frases va ser quantificada. La repetibilitat i la correlació va ser determinada per les dues mesures. Resultats: les proves van ser realitzades en 22 subjectes sans: 11 subjectes joves (edat mitja 27±3.91) i 11 de mitjana edat (edat mitja 53±4.52). La VL als subjectes joves va ser 249±15.87 ppm i de 223.72±18.46 ppm en els subjectes de mitjana edat. La AVL va ser -0.1±0.07 logMAR al grup jove i -0.05±0.08 logMAR al gruo de mitjana edat. Estadísticament es va obtenir una baixa concordança entre la AVL i la AV en visió pròxima, no obstant el resultats indiquen una bona correlació clínica. Els coeficients de repetibilitat mostren en els dos grups una bona repetibilitat: AVL (Kappa=0.71 i 0.65) i VL (Kappa=0.75 i 0.85). Conclusions: l’estudi que presentem indica que les frases seleccionades son una bona base per desenvolupar un test de lectura vàlid i altament estandarditzat. Es deurien fer més estudis amb la finalitat de establir i validar el test.
