Hearing in Real-Life Environments (HERE): Structure and Reliability of a Questionnaire on Perceived Hearing for Older Adults

Objectives: The ability to hear in a variety of social situations and environments is vital for social participation and a high quality of life. One way to assess hearing ability is by means of self-report questionnaire. For questionnaires to be useful, their measurement properties, based on careful validation, have to be known. Only recently has consensus been reached concerning how to perform such validation and been published as COSMIN (consensus-based standards for the selection of health status measurement instruments) guidelines. Here the authors use these guidelines to evaluate the measurement properties of the "Hearing in Real-Life Environments" (HERE) questionnaire, a newly developed self-report measure that assesses speech perception, spatial orientation, and the social-emotional consequences of hearing impairment in older adults. The aim is to illustrate the process of validation and encourage similar examinations of other frequently used questionnaires. Design: The HERE questionnaire includes 15 items with a numeric rating scale from 0 to 10 for each item and allows the assessment of hearing with and without hearing aids. The evaluation was performed in two cohorts of community-dwelling older adults from Finland (n = 581, mean 82 years) and the United Kingdom (n = 50, mean 69 years). The internal structure of the questionnaire and its relationship to age, hearing level, and self-reported and behavioral measures of speech perception was assessed and, when possible, compared between cohorts. Results: The results of the factor analysis showed that the HERE's internal structure was similar across cohorts. In both cohorts, the factor analysis showed a satisfactory solution for three factors (speech hearing, spatial hearing, and socio-emotional consequences), with a high internal consistency for each factor (Cronbach's α's for the factors from 0.90 to 0.97). Test–retest analysis showed the HERE overall mean score to be stable and highly replicable over time (intraclass correlation coefficient = 0.86, standard error of measurement of the test score = 0.92). The HERE overall mean score correlated highly with another self-report measure of speech perception, the Speech Spatial Qualities of Hearing questionnaire (standardized regression coefficient [β] = −0.75, p

Behavioral Measures of Listening Effort in School-Age Children: Examining the Effects of Signal-to-Noise Ratio, Hearing Loss, and Amplification

Objectives: Increased listening effort in school-age children with hearing loss (CHL) could compromise learning and academic achievement. Identifying a sensitive behavioral measure of listening effort for this group could have both clinical and research value. This study examined the effects of signal-to-noise ratio (SNR), hearing loss, and personal amplification on 2 commonly used behavioral measures of listening effort: dual-task visual response times (visual RTs) and verbal response times (verbal RTs). Design: A total of 82 children (aged 6–13 years) took part in this study; 37 children with normal hearing (CNH) and 45 CHL. All children performed a dual-task paradigm from which both measures of listening effort (dual-task visual RT and verbal RT) were derived. The primary task was word recognition in multi-talker babble in three individually selected SNR conditions: Easy, Moderate, and Hard. The secondary task was a visual monitoring task. Listening effort during the dual-task was quantified as the change in secondary task RT from baseline (single-task visual RT) to the dual-task condition. Listening effort based on verbal RT was quantified as the time elapsed from the onset of the auditory stimulus to the onset of the verbal response when performing the primary (word recognition) task in isolation. CHL completed the task aided and/or unaided to examine the effect of amplification on listening effort. Results: Verbal RTs were generally slower in the more challenging SNR conditions. However, there was no effect of SNR on dual-task visual RT. Overall, verbal RTs were significantly slower in CHL versus CNH. No group difference in dual-task visual RTs was found between CNH and CHL. No effect of amplification was found on either dual-task visual RTs or verbal RTs. Conclusions: This study compared dual-task visual RT and verbal RT measures of listening effort in the child population. Overall, verbal RTs appear more sensitive than dual-task visual RTs to the negative effects of SNR and hearing loss. The current findings extend the literature on listening effort in the pediatric population by demonstrating that, even for speech that is accurately recognized, school-age CHL show a greater processing speed decrement than their normal-hearing counterparts, a decrement that could have a negative impact on learning and academic achievement in the classroom.

Telephone-Based Progressive Tinnitus Management for Persons With and Without Traumatic Brain Injury: A Randomized Controlled Trial

Objectives: This randomized controlled trial evaluated the efficacy of delivering coping skills education from Progressive Tinnitus Management (PTM) by telephone (Tele-PTM). The trial followed a previous pilot study that showed positive results for Tele-PTM. Design: Participants included individuals with bothersome tinnitus (N = 205) located anywhere within the United States. A special emphasis was given to including individuals who had experienced one or more traumatic brain injuries (TBIs). Participants were randomized to either Tele-PTM intervention or 6-month wait-list control (WLC). The Tele-PTM intervention involved five telephone appointments—two led by an audiologist (teaching how to use therapeutic sound) and three by a psychologist (teaching coping skills derived from cognitive-behavioral therapy). It was hypothesized that Tele-PTM would be more effective than WLC in reducing functional effects of tinnitus as measured with the Tinnitus Functional Index. Additional outcome measures included the Self-Efficacy for Managing Reactions to Tinnitus questionnaire and the Hospital Anxiety and Depression Scale. The effect of Tele-PTM on outcomes was estimated using linear mixed models. Results: Overall results showed convincingly that the Tele-PTM group had significantly better outcomes than the WLC group. These results were consistent across all outcome measures, indicating not only a reduction of tinnitus functional distress but also increased self-efficacy. Improvements in measures of anxiety and depression were also observed. Tele-PTM participants in all TBI categories showed significant improvement. Conclusions: Results provide strong support for use of Tele-PTM methodology for persons with bothersome tinnitus, regardless of whether the person also has TBI symptoms. The effect size for Tele-PTM was high for the primary outcome measure, the Tinnitus Functional Index, and all other outcome measures showed significant improvement. Combined with our previous pilot study, the Tele-PTM method is validated for potential nationwide provision of tinnitus services.

Do Personality Factors Assessed Before Cochlear Implantation Predict Hearing-Related Quality Of Life After Cochlear Implantation in Postlingually Deafened Adults?

Background: Studies have shown that cochlear implants improve deaf patients' hearing-related quality of life (hrQoL), but the degree of improvement varies considerably between patients. This study investigated whether personality factors contribute to hrQoL outcome after cochlear implantation. Method: Fifty adult patients with postlingual hearing loss who received a unilateral cochlear implant were administered the Neuroticism-Extraversion-Openness Five-Factor Inventory (NEO-FFI; a personality inventory) and the Nijmegen Cochlear Implant Questionnaire (NCIQ; a hrQoL questionnaire). The NEO-FFI was administered only before implantation; the NCIQ was administered before implantation and 12 months after implant activation. A linear regression analysis was computed to detect whether NCIQ scores at 12 months were predicted by the NEO-FFI personality factors (i.e., Extraversion, Neuroticism, Openness to Experience, Agreeableness, and Conscientiousness) assessed before implantation. Results: HrQoL scores had significantly improved 12 months after cochlear implantation in all subdomains of the NCIQ. Of the five personality factors, solely Neuroticism was negatively associated to the NCIQ subdomain self-esteem (β = −0.34; p = 0.013) at 12 months after cochlear implantation. Conclusions: 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.

Predictors of Reading Skills in Children With Listening Concerns

Objectives: Previous research shows that children with reading disorders perform poorly on auditory processing (AP) tasks. Correlational studies have also shown significant associations between some AP tasks and word and nonword reading. There is less clear evidence for AP contributions to spelling and passage reading. The aim of this research was to extend current knowledge by investigating the association between a range of AP measures used clinically and children's reading of words, nonwords, and passages, as well as word spelling. Design: Regression analyses were conducted on data from 90 children 7 to 13 years of age (58 males) with reported listening and/or reading concerns. All children had normal hearing sensitivity and were tested on AP tasks including the frequency pattern test (FPT), dichotic digits test, random gap detection test, and the masking level difference. Reading tasks included word, nonword, and passage reading. Phonologic processing, core language skills, nonverbal intelligence, memory, and attention were also measured. Results: All multiregression analyses were fixed order with age and gender, nonverbal intelligence, core language, phoneme manipulation, and digits backward scores included in the model before AP measures. FPT was the only AP task that accounted for significant unique variance in word/nonword reading and nonword spelling, but not passage reading. Conclusions: The findings from this study failed to show an association between many clinically used AP measures and children's reading and spelling outcomes. Nevertheless, they reiterate the importance of evaluating FPT in children with word reading disorders. The findings justify further investigation into the role of this test when diagnosing children with reading or spelling disorders.

Effects of Various Trajectories on Tissue Preservation in Cochlear Implant Surgery: A Micro-Computed Tomography and Synchrotron Radiation Phase-Contrast Imaging Study

Objectives: The purpose of this study was to evaluate the three-dimensional (3D) anatomy and potential damage to the hook region of the human cochlea following various trajectories at cochlear implantation (CI). The goal was to determine which of the approaches can avoid lesions to the soft tissues, including the basilar membrane and its suspension to the lateral wall. Currently, there is increased emphasis on conservation of inner ear structures, even in nonhearing preservation CI surgery. Design: Micro-computed tomography and various CI approaches were made in an archival collection of macerated and freshly fixed human temporal bones. Furthermore, synchrotron radiation phase-contrast imaging was used to reproduce the soft tissues. The 3D anatomy was investigated using bony and soft tissue algorithms, and influences on inner ear structures were examined. Results: Micro-computed tomography with 3D rendering demonstrated the topography of the round window (RW) and osseous spiral laminae, while synchrotron imaging allowed reproduction of soft tissues such as the basilar membrane and its suspension around the RW membrane. Anterior cochleostomies and anteroinferior cochleostomies invariably damaged the intracochlear soft tissues while inferior cochleostomies sporadically left inner ear structures unaffected. Conclusions: Results suggest that cochleostomy approaches often traumatize the soft tissues at the hook region at CI surgery. For optimal structural preservation, the RW approach is, therefore, recommended.
