Abstract Objective: This study presents German versions of the ECHO (expected consequences of hearing aid ownership) and SADL (satisfaction with amplification in daily life) self-assessment inventories ( Cox et al, 1999 , 2000 ). Study sample: The questionnaires were administered to a group of 290 hearing-aid candidates (ECHO) and 462 experienced hearing-aid users (SADL) recruited at different audiological centres in Germany. Design: The psychometric properties of the German versions and the original questionnaires were similar as confirmed by factor analysis and internal consistency analysis. Results: When comparing outcomes for the ECHO and SADL inventories from the two study groups it was found that satisfaction outperformed expectations. In addition, the relationships of the questionnaire subscales with personality traits as measured with the Big Five inventory were examined. Certain weak though statistically significant correlations were found revealing that personality in hearing-impaired persons does not greatly affect ECHO and SADL outcomes. In contrast, ECHO subscale scores were clearly associated with the motivation to use amplification and might thus help to detect non-adherents. Conclusion: These findings, along with the fact that pre-fitting expectations can be directly compared to post-fitting satisfaction, makes the application of the ECHO and SADL inventories highly valuable in rehabilitative audiology. Sumario Objetivo: Este estudio presenta las versiones en alemán de los cuestionarios de auto-evaluación ECHO (consecuencias esperadas de usuarios de auxiliares auditivos) y SADL (satisfacción con la amplificación en la vida diaria) ( Cox y cols., 1999 , 2000 ). Muestra de estudio: Se administraron los cuestionarios a un grupo de 290 candidatos al uso de auxiliares auditivos (ECHO) y a 462 usuarios experimentados de auxiliares auditivos (SADL), reclutados en diferentes centros audiológicos de Alemania. Diseño: Las propiedades psicométricas de las versiones en alemán y los cuestionarios originales fueron similares, según fue confirmado por el factor de análisis y por el análisis de consistencia interna. Resultados: Al comparar los resultados del ECHO y del SADL de los dos grupos de estudio, se encontró que la satisfacción sobrepasó a las expectativas. Además, se examinaron las relaciones de las subescalas del cuestionario con los rasgos de personalidad medidos con el cuestionario Big Five. Se encontraron algunas correlaciones débiles pero estadísticamente significativas, revelando que la personalidad de las personas con impedimentos auditivos no afecta importantemente los resultados del ECHO y del SADL. En contraste, las puntuaciones de la subescala del ECHO fueron claramente asociadas con la motivación para usar la amplificación, por lo que puede ayudar a detectar a los no adherentes. Conclusión: Estos hallazgos, junto con el hecho de que las expectativas antes de la adaptación pueden ser comparadas directamente con la satisfacción después de la adaptación, hace que la aplicación del ECHO y del SADL sean muy valiosas en la audiología rehabilitatoria. |
