“…Clinical routine outcomes consist of CI- and HA-aided speech comprehension in quiet and noise. In research studies, performance in audiometric tests shows substantial dependence on the type of speech material, on the nature of noise confounders, and on spatial distribution of speech and noise sources ( 8 – 10 ). Furthermore, during audiometric tests pronunciation is clear, spectro-temporal characteristics and location of the speaker as well as noise type are static and thus predictable, and predictability increases the performance of CI-patients.…”

“…Moreover, a benefit version, the SSQ-B, has been developed for the assessment of self-perceived improvements following an intervention ( 21 , 22 ). At present, few studies have examined both audiometric and self-reported outcomes assessed with the SSQ for bimodal CI-users ( 5 – 8 , 23 – 30 ). These studies evidence large inter-individual variability as well as inconsistent connections between audiometry and self-report.…”

Objectives: Patient-reported outcomes gain importance for the assessment of auditory abilities in cochlear implant users and for the evaluation of auditory rehabilitation. Aims of the study were to explore the interrelation of self-reported improvements in auditory ability with improvements in speech comprehension and to identify factors other than audiological improvement that affect self-reported auditory ability.Study Design: Explorative prospective analysis using a within-subjects repeated measures design.Setting: Academic tertiary care center.Participants: Twenty-seven adult participants with bilateral sensorineural hearing loss who received a HiRes 90K CI and continued use of a HA at the non-implanted ear (bimodal hearing).Intervention: Cochlear implantation.Main Outcome Measures: Self-reported auditory ability/disability assessed by the comparative version of the Speech, Spatial and Qualities of Hearing Scale (SSQ-B), and monosyllable as well as sentence comprehension in quiet and within speech modulated noise from different directions assessed pre- as well as 3 and 6 months post-implantation.Results: Data of 17 individuals were analyzed. At the endpoint of the study, improvement of self-reported auditory ability was significant. Regarding audiometric measures, significant improvement was seen for CI-aided pure tone thresholds, for monaural CI-assisted and bimodal sentence comprehension in quiet and in speech-modulated noise that was presented from the same source or at the side of the HA-ear. Correlations between self-reported and audiometric improvements remained weak, with the exception of the improvement seen for monaural CI-aided sentence comprehension in quiet and self-perceived improvement of sound quality. Considerable correlations existed between self-reported improvements and current level of depression and anxiety, and with general self-efficaciousness. Regression analyses substantiated a positive influence of self-efficaciousness on self-reported improvement in speech comprehension and between the improvement of monaural CI-aided sentence comprehension in quiet and perceived sound quality as well as a negative influence of anxiety on self-reported improvement in spatial hearing. Self-reported improvements were significantly better in the subgroup with intensive as compared to regular rehabilitation.Conclusions: Self-reported auditory ability/disability represents an important measure for the success of bimodal CI-provision. It is influenced by personal and mental health factors that may improve CI-rehabilitation results if addressed during rehabilitation.

BackgroundThere are many methods for assessing hearing performance after cochlear implantation. Standard evaluations often encompass objective hearing tests only, while patients’ subjective experiences gain importance in today’s healthcare. The aim of the current study was to analyze the correlation between subjective (self-reported questionnaires) and objective (speech perception and localization) hearing test results in adult cochlear implant (CI) users. Secondary, the correlation between subjective and objective hearing tests was compared between bilateral and unilateral CI patients.MethodsData for this study were prospectively collected as part of a multicentre randomized controlled trial. Thirty-eight postlingually deafened adult patients were randomly allocated to receive either unilateral (n = 19) or bilateral (n = 19) cochlear implantation. We used data gathered after one year of follow-up. We studied the correlation between objectively measured speech perception and localization skills on the one hand and related domains of the Speech, Spatial and Qualities of Hearing Scale (SSQ) and Nijmegen Cochlear Implant Questionnaire (NCIQ) on the other hand. We also compared these correlations between unilateral and bilateral CI users.ResultsWe found significant weak to moderate negative correlations between the subjective test results (speech domain of the SSQ and the advanced speech perception domain of the NCIQ) and the related objective speech perception in noise test results (r = −0.33 to −0.48). A significant moderate correlation was found between the subjective test results (spatial domain of the SSQ) and the related objective localization test results (r = 0.59). The correlations in the group of bilateral CI patients (r = −0.28 to −0.54) did not differ significantly from the correlations in the group of unilateral CI patients (r = 0.15 to −0.40).ConclusionsCurrent objective tests do not fully reflect subjective everyday listening situations. This study elucidates the importance and necessity of questionnaires in the evaluation of cochlear implantation. Therefore, it is advised to evaluate both objective and subjective tests in CI patients on a regular basis.Trial registrationThis trial was registered on March 11, 2009 in the Dutch Trial Register. Trial registration number: NTR1722.

“…Laske et al (2009) demonstrated that there was a statistically significant correlation of the results from the localization test and the section of the SSQ on spatial hearing (p < .05) in a study to assess subjective and objective results in 34 consecutive bilaterally implanted adult patients. However, Heo, Lee, and Lee (2013) found that the relationships were not always consistent between the objective outcomes and the subjective self-reports in a study aimed to measure the hearing aid and CI benefits on the objective and subjective outcomes for adults. To better document the benefits of the CI performances, a study that focuses on questionnaires and objective result correlation is needed.…”

Purpose The purpose of the present study is to evaluate the changes over time of the Spatial Hearing Questionnaire (SHQ; Tyler, Perreau, & Ji, 2009) and the Speech, Spatial and Qualities of Hearing Scale (SSQ; Gatehouse & Noble, 2004) in adults with simultaneous bilateral cochlear implants by collecting data for 2 years after implantation. Method Nineteen postlingual subjects participated in this study. Average age at implant was 63 years. The subjects' data were included in this retrospective analysis only if they completed both questionnaires. We compared subjects' SSQ and SHQ scores to word recognition and sound localization performances. Results The study showed SHQ and SSQ scores continuously improved up to 1 year postimplantation, with the most improvement occurring within the first 6 months of implantation. After 1 year, the scores reached a plateau. This is consistent with laboratory tests from the same 19 subjects, and they showed high correlations ( p < .05). The present study also showed a high degree of correlation between SHQ and SSQ scores. Conclusions Both the SSQ and SHQ scores improved up to 12 months postimplantation, with the most improvement during the first 6 months of implantation. Both were consistent with laboratory tests. There was a high degree of correlation between SHQ and SSQ scores.
