Abstract
The Meaningful Auditory Integration Scale (MAIS) is a parent-report questionnaire for assessing auditory behaviour in aurally habilitated children. This study addressed the reliability and convergent validity of three different language versions of the MAIS: English, German, and Polish. In total, 114 parents (English, n=27; Polish, n=37; German, n=50) completed the MAIS preoperatively and at 6 months after cochlear implantation. Internal reliability (Cronbach's alpha) ranged from 0.92 to 0.95 preoperatively, and from 0.87 to 0.93 at 6 months. Split-half reliability was at least 0.90 preoperatively, and ranged from 0.76 to 0.89 at 6 months. Corrected item-total correlation coefficients were significant (p<0.05) for all items except for item 1, which showed poor correlations in the Polish version. Correlation of the MAIS with the Listening Progress Profile (LiP), as a measure for convergent validity, yielded coefficients between 0.81 and 0.73 preoperatively, and between 0.79 and 0.61 at 6 months. These findings demonstrate high reliability and convergent validity of the three MAIS versions.
Sumario
La Escala de Integracio´n Auditiva Significativa (MAIS) es un cuestionario que se aplica a los padres para evaluar la conducta auditiva de nin˜os habilitados auditivamente. Este estudio analizo´ la utilidad y la validacio´n convergente del MAIS en tres versiones lingu¨i´sticas: ingle´s, alema´n y polaco. En total, 114 padres (ingle´s, n=27; polaco, n=37; alema´n, n=50) respondieron el MAIS antes de la operacio´n y 6 meses despue´s de implantacio´n coclear. La consistencia interna (alfa de Cronbach) vario´ de 0.92 a 0.95 en el preoperatorio y de 0.87 a 0.93 a los 6 meses. La consistencia de la mitad dividida fue de al menos 0.90 en el preoperatorio y vario´ de 0.76 a 0.89 a los 6 meses. El coeficiente de correlacio´n del total de los items correctos fue significativo (p<0.05) para todos los items excepto el nu´mero 1, que mostro´ una pobre correlacio´n en la versio´n polaca. La correlacio´n del MAIS con el Perfil de Progreso de Escucha (LiP), como medida de validez de convergencia, demostro´ coeficientes entre 0.81 y 0.73 en el preoperatorio y entre 0.79 y 0.61 a los 6 meses. Estos hallazgos demostraron alta consistencia y validez de convergencia de las tres versiones del MAIS.
