Abstract
Objective: The objective of the study was to investigate the cross-cultural validity and reliability of the Chinese version of the Abbreviated Profile of the Hearing Aid Benefit questionnaire (APHAB-CH). Design: A convenience sampling method was used to identify and recruit subjects. The subjects completed a history form seeking demographic data, the APHAB-CH, and a questionnaire seeking a subjective rating of hearing aid performance and overall satisfaction with their hearing aid. Study Sample: The subjects were 134 experienced hearing aid users. Results: The APHAB-CH had a good internal consistency reliability estimate (α = 0.85) comparable to that of the original version. Significant correlation was observed between the APHAB-CH scores and other subjective ratings for hearing aid performance and the overall satisfaction measure. A high test-retest reliability (intraclass correlation coefficient = 0.84) was observed. Confirmatory factor analysis revealed that the APHAB-CH had a two-factor structure comprising “hearing disability” and “averviseness.” Normative data in terms of equal-percentile profiles were dervied for the APHAB-CH. Conclusion: The results suggest that the APHAB-CH is a reliable and valid measure of the outcomes of hearing aid fittingSumarioObjetivo: El objetivo de este estudio fue investigar la validez y confiabilidad transcultural de la versión china del Cuestionario de Perfil Abreviado de Beneficios del Auxiliar Auditivo (APHAB-CH). Diseño: Se usó un método conveniente de muestreo para identificar y reclutar sujetos. Los sujetos completaron un formulario de historia para obtener datos demográficos, el APHAB-CH, y un cuestionario para encontrar los rangos subjetivos de rendimiento del auxiliar auditivo y de satisfacción general con el mismo. Muestra de Estudio: Los sujetos fueron 134 usuarios experimentados en el uso de auxiliar auditivo. Resultados: El APHAB-CH tuvo un estimado de confiabilidad con buena consistencia interna (α = 0.85) comparable con la de la versión original. Se observó una correlación significativa entre las puntuaciones del APHAB-CH con otras puntuaciones subjetivas de rendimiento del auxiliar auditivo y de mediciones de satisfacción general. Se observó una alta confiabilidad test-retest (coeficiente de correlación interno = 0.84). El análisis de factor de confirmación reveló que el APHAB-CH tuvo una estructura de dos factores que comprendía la “discapacidad auditiva” y la “aversión” Los datos normativos en términos de perfiles de igual percentil, se derivaron del APHAB-CH. Conclusion: Los resultados sugieren que el APHAB-CH es una medida válida y confiable de los resultados de la adaptación de auxiliares auditivos.
