Spanish translation and validation of the Music-Related Quality of Life Questionnaire (MuRQoL) in postlingually deaf cochlear implant users.
European Archives of Oto-rhino-laryngology 2024 April 27
PURPOSE: The aim of this study was to translate and validate the "Music-Related Quality of Life Questionnaire" into Spanish (sMuRQoL) and assess its convergent validity and discriminative capacity by comparing its scores with the outcomes of the musical perception test Meludia.
METHODS: The sMuRQoL was completed by 129 patients: 55 cochlear implant (CI) users and 74 normal hearing (NH) individuals. Conducted in this study were an exploratory factor analysis, an evaluation of internal consistency, an assessment of score stability through test-retest reliability, a comparison of sMuRQoL scores between CI users and NH individuals and an examination of potential evidence of convergent validity and discriminative capacity of sMuRQoL in relation to other tools. This involved the comparison of the questionnaire scores with the Meludia outcomes.
RESULTS: The sMuRQoL demonstrated a two-dimensional structure. All the dimensions displayed high internal consistency (α = 0.879-0.945) and score stability (ICC = 0.890-0.942). There were significant differences in the Frequency test between NH and CI users (d = 1.19-1.45). There's evidence of convergent validity between the scores of the Frequency test and the results of Meludia (r = 0.242-0.645). Additionally, the Frequency test demonstrate a good discriminative capacity to identify patients with poorer musical perception.
CONCLUSIONS: The sMuRQoL is a reliable questionnaire, with adequate evidence of validity based on internal structure. This study provides an accessible, cost-effective, and quick-to-administer instrument in Spanish, optimizing available healthcare resources and bringing us closer to the patient needs.
