ObjectivesThe aim was to construct validity and reliability of the Hearing Implant Sound Quality Index Questionnaire (HISQUI19) in Turkish. MethodsThis study was a methodologic study to validate HISQUI19 in Turkish. The study included 62 cochlear implant users. Guttman's split half-coefficient and Cronbach's alpha tests were used for construct validity and internal consistency. Pearson correlation test was used to assess the relationship of the HISQUI19 total score to the SSQ49 scales for CI users and to show test - retest reliability. ResultsThe Cronbach's alpha value was 0.94 overall score with high internal consistency (Guttman's split-half-coefficient: 0.912). Test-retest reliability results showed high repeatability and consistency of the measure across time (r = 0.708; P = 0.002). Support for conducting factor analysis was provided by the KMO test, with a value of 0.876, which is 'great'. DiscussionSubjective evaluation of cochlear implant users' daily life experiences is a useful tool to reveal the auditory benefits of cochlear implant usage. ConclusionTurkish version of the HISQUI19 is a reliable and valid assessment tool for adults with CIs. This questionnaire provides clinicians with a valuable, reliable, and valid tool for determining the subjective benefit of CI for patients.
