Validation of the Hearing Implant Sound Quality Index (HISQUI19) to assess Spanish-speaking cochlear implant users' auditory abilities in everyday communication situations.

CONCLUSION: The Spanish-language HISQUI19 is a reliable and easy-to-use tool for quantifying the self-perceived level of auditory benefit that cochlear implant (CI) users experience in everyday listening situations.
OBJECTIVES: To validate the Spanish-language version of The Hearing Implant Sound Quality Index (HISQUI19), a questionnaire for quantifying the self-perceived level of auditory benefit that CI users experience in everyday listening situations.
METHODS: Adult Spanish-speaking subjects with a CI were asked to complete a Spanish-language version of the HISQUI19. Reliability of the questionnaire was determined using Cronbach's α coefficient; exploratory factor analyses with a rotated (varimax) factor solution was applied to check construct validity; external validity was confirmed using Pearson's correlation. Test-re-test analysis was also performed. The MED-EL Assessment Database was used to assist in the administration, reporting, and data collection.
RESULTS: Sixty-six of 77 subjects completed and returned the HISQUI19. The mean score auditory ability score (mean ± standard deviation) of the HISQUI19 was 79.9 ± 24.0, a 'moderate' auditory benefit. An inverse relationship was found between the HISQUI19 score and age at implantation. Gender and side of implantation did not influence self-perceived functioning. The objective measures (disyllables tested without lip-reading and in quiet) were correlated with the Total Score.
