A Persian cross-cultural validation and adaptation of the Hearing Implant Sound Quality Index Questionnaire for cochlear implant adult users
Abstract
Background and Aim: Cochlear implants (CIs) successfully improve speech and auditory skills for patients with a severe‑to‑profound degree of hearing loss. The psychometric properties of the Hearing Implant Sound Quality Index Persian version (P‑HISQUI19) were examined to measure auditory benefits in CI recipients in everyday life.
Methods: Seventy post-lingual CI users, aged 18-64 years, completed the P‑HISQUI19. Cross‑cultural adaptation of the P‑HISQUI19 was performed. Internal consistency and test–retest reliability were measured by Cronbach’s α and intra‑class correlation coefficients. The content and construct validity of the questionnaire were also examined.
Results: The P‑HISQUI19 average total score in implanted cases was 78.22, representing a moderate sound quality. The P‑HISQUI19 indicated excellent internal consistency reliability (Guttman’s split‑half‑coefficient = 0.912; Cronbach’s α =0.956) and test–retest reliability (r = 0.962). Our data proceeded to factor analysis, and the questionnaire items were loaded on three factors. In addition, factors such as age at implantation, duration of deafness, side of implantation, and gender factors did not significantly affect sound quality perception.
Conclusion: The P‑HISQUI19 is a valid and reliable measure, which should be beneficial in both research and clinical settings for evaluating the auditory benefits of those using CI during listening.
