Abstract

Conclusions: The Hearing Implant Sound Quality Index (HISQUI19) seems to be a valid tool for quantifying the self-perceived level of auditory benefit that cochlear implant (CI) users experience in everyday listening situations. Additional research is, however, required. Objectives: To develop and validate a user-friendly instrument for quantifying the self-perceived level of auditory benefit that CI users experience in everyday listening situations. Methods: This was an explorative, uncontrolled, single-group, cross-sectional study. Items for the HISQUI19 were decided upon using user input and verified by professionals. The HISQUI19 was assessed on 75 CI users from hearing implant centres in Germany and Austria to determine the questions. Results: The HISQUI19, consisting of 19 items scored on a 7-point Likert scale, was validated. Subjects older than 60 years at time of implantation did not have significantly higher mean values than subjects younger than 60 years. Gender and whether subjects are unilateral or bilateral implant CI users did not influence self-perceived functioning. Subjects with ≤20 years of hearing loss reported no significantly higher functioning than those with >20 years of hearing loss.
