Abstract
Purpose: The present study aimed to describe the adaptation and validation process of the MuRQoL (Music Related Quality of Life questionnaire) from English to Hebrew and to describe normative data from a cohort of adults with normal hearing versus those with hearing aids or cochlear implants. Methods: After thoroughly translating and adapting to Hebrew, the participants completed the questionnaire online. We calculated the Cronbach's alpha and McDonald's omega scores for all scales and subscales. The construct validity of the questionnaire was evaluated using Confirmatory Factor Analysis (CFA) and the "known group" method. A total of 310 adults participated in this study. Fifty-four participants were deaf or hard of hearing, and 256 had normal hearing. Results: Internal consistency of the MuRQoL-He scales and subscales demonstrated good-to-excellent reliability. The goodness-of-fit indices for the frequency and importance scales were within acceptable standards. We found a significant difference in the frequency scale, where the normal-hearing group scores were significantly higher than those of the deaf and hard-of-hearing groups. Conclusions: The validity and reliability of the MuRQoL-He have been confirmed, indicating that it is suitable for guiding music rehabilitation for Hebrew-speaking deaf and hard-of-hearing adults.
