While significant improvement of hrQoL was seen 12 months after implant activation, this improvement was barely predicted by the Big-Five personality traits measured before implantation. Only Neuroticism was found to moderately influence postimplantation hrQoL in our patients, in the way that higher degrees of Neuroticism tend to go along with lower degrees of self-esteem (as conceptualized by the NCIQ). The failure to detect personality effects on hrQoL could partly be due to the low levels of Extraversion and Openness to Experience observed in our sample of patients with hearing loss.
BackgroundOnly few studies assessed health-related quality of life (HRQoL) in cochlear implant (CI) patients for a period of more than 2 years. Some of these studies indicated that HRQoL might decrease after that period. The goal of our study was to see whether HRQoL indeed decreases or remains stable beyond 2 years after implant activation.MethodsTwenty-five adults (11 women, 14 men; mean age at implantation: 60 ± 19 yr) with a unilateral CI for profound hearing loss were administered two questionnaires: the Nimjegen Cochlear Implant Questionnaire and the Health Utility Index 3 (HUI 3). The Nimjegen Cochlear Implant Questionnaire total score and the HUI single-attribute utility score of Hearing are measures of hearing-specific HRQoL, whereas the HUI multiattribute utility score is a measure of generic HRQoL. The questionnaires were administered before cochlear implantation and 1, 2, and 5 years after implant activation.ResultsHearing-specific HRQoL was significantly improved at 1 year after implant activation and did not significantly change thereafter. Generic HRQoL also showed significant improvement at 1 year after implant activation, but deteriorated to a clinically relevant degree thereafter.ConclusionsThe significant improvement of hearing-specific HRQoL obtained from cochlear implantation was fully maintained for up to 5 years after implantation. Generic HRQoL of our CI patients, however, fluctuated over time. The decrease of generic HRQoL is supposed to reflect general age-associated health declines.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
