ABSTRACT

PURPOSE: The purpose of this study was to examine quality of life (QOL) and its relation to language skills in children with developmental language disorder (DLD). This was examined by comparing QOL to a control group of children with typical development (TD), as well as children with cochlear implants (CIs), who potentially struggle with language for language, although for a different reason than children with DLD. METHOD: Two groups of children, a group with TD (n = 29) and a group of children with CIs (n = 29), were matched to the DLD group (n = 29) on chronological age, gender, nonverbal IQ, and parental educational level through a propensity matching procedure. A third group consisting of children with CIs was also matched to the DLD group but additionally matched on language abilities. QOL scores were compared across groups, and the association between language skills and QOL was examined in the DLD group. RESULT: The DLD group was reported by parents to have statistically significantly poorer QOL scores than peers with TD or CIs. When controlling for language skills, either statistically or through an additional CI group matched on language abilities, there were no statistically significant differences in QOL scores across groups. In the DLD group, language skills explained 16% of the variation in QOL. CONCLUSION: DLD is associated with the children's overall QOL, and the degree of reduced QOL relates to the severity of the language impairment.

ABSTRACT

OBJECTIVES: The vocabulary of children with cochlear implants is often smaller than that of their peers with typical hearing, but there is uncertainty regarding the extent of the differences and potential risks and protective factors. Some studies indicate that their receptive vocabulary develops well at first, but that they fail to keep up with their typical hearing peers, causing many CI users to enter school with a receptive vocabulary that is not age-appropriate. To better understand the receptive vocabulary abilities of children with cochlear implants this study explored age-related differences to matched children with typical hearing and associations between vocabulary skills and child-level characteristics. DESIGN: A retrospective cross-sectional study with matched controls was conducted at the Norwegian national cochlear implant center at Oslo University Hospital. Eighty-eight children (mean age 8.7 years; range 3.2 to 15.9; 43 girls, 45 boys) who had received bilateral cochlear implants before 3 years of age were compared with two groups of children with typical hearing. One group was matched for maternal education, sex, and chronological age, the other group was matched for maternal education, sex, and hearing age. Receptive vocabulary performance was measured with the British Picture Vocabulary Scale. RESULTS: Cochlear implant users' receptive vocabulary was poorer than that of age-matched children with typical hearing ( M = 84.6 standard points, SD = 21.1; children with typical hearing: M = 102.1 standard points, SD = 15.8; mean difference -17.5 standard points, 95% CI [-23.0 to -12.0], p < 0.001; Hedges's g = -0.94, 95% CI [-1.24 to -0.62]), and children with cochlear implants were significantly more likely to perform below the normative range (risk ratio = 2.2, 95% CI [1.42 to 3.83]). However, there was a significant nonlinear U-shaped effect of age on the scores of cochlear implant users, with the difference to the matched typical hearing children being largest (23.9 standard points, on average) around 8.7 years of age and smaller toward the beginning and end of the age range. There was no significant difference compared with children with typical hearing when differences in auditory experience were accounted for. Variability was not significantly different between the groups. Further analysis with a random forest revealed that, in addition to chronological age and hearing age, simultaneous versus sequential implantation, communication mode at school, and social integration were predictors of cochlear implant users' receptive vocabulary. CONCLUSIONS: On average, the receptive vocabulary of children with cochlear implants was smaller than that of their typical hearing peers. The magnitude of the difference was changing with age and was the largest for children in early primary school. The nonlinear effect of age might explain some of the ambiguity in previous research findings and could indicate that better intervention is required around school entry. The results emphasize that continuous monitoring and support are crucial to avoid far-reaching negative effects on the children's development and well-being.

ABSTRACT

OBJECTIVES: This study compared the parent-reported structural language and social communication skills-measured with the Children's Communication Checklist-2 (CCC-2)-and health-related quality of life (HR-QOL)-measured with the Pediatric Quality of Life Inventory (PedsQL)-of children who use hearing aids (HAs) and their typical-hearing (TH) peers. DESIGN: The participants were 88 children (age range of 5; 6 to 13; 1 (years; months)) and their parents: 45 children with bilateral moderate to severe hearing loss using HAs who had no additional disabilities and 43 children with typical hearing. The groups were matched based on chronological age, gender, nonverbal IQ, and parental education level. The parents completed questionnaires related to their children's communication skills, including subdomains structural language and social communication, and HR-QOL. RESULTS: The HA group had significantly poorer overall communication skills than the TH group (r = 0.49). The children in the HA group scored significantly lower than the TH group on both structural language (r = 0.37) and social communication (r = 0.41). Half of the children in the HA group had overall communication scores that either indicated concern or required further investigation according to the instrument's manual. In terms of psychosocial functioning, which was measured as HR-QOL, the subdomain school functioning was the main driver of the difference between groups, with the HA group being at least twice as likely (OR = 2.52) as the TH group to have poor HR-QOL in the school domain. Better parent-reported social communication was associated with better parent-reported psychosocial functioning in the children using HAs-even when background variables were taken into account. CONCLUSION: The results suggest that traditional assessments and interventions targeting structural aspects of language may overlook social communication difficulties in children with HAs, even those with no additional disabilities. As school functioning stood out as the most problematic domain for children with HAs, efforts to improve the well-being of these children should focus on this area.

ABSTRACT

OBJECTIVES: This longitudinal study followed the language development of children who received the combination of early (5 to 18 months) and simultaneous bilateral cochlear implants (CIs) throughout the first 6 years after implantation. It examined the trajectories of their language development and identified factors associated with language outcomes. DESIGN: Participants were 21 Norwegian children who received bilateral CIs between the ages of 5 and 18 mo and 21 children with normal hearing (NH) who were matched to the children with CIs on age, sex, and maternal education. The language skills of these two groups were compared at 10 time points (3, 6, 9, 12, 18, 24, 36, 48, 60, and 72 months after implantation) using parent reports and standardized measures of general language skills, vocabulary, and grammar. In addition, assessments were made of the effects of age at CI activation, speech recognition abilities, and mothers' education on language outcomes 6 years after implantation. RESULTS: During the first 4 years after implantation, the gap in general expressive and receptive language abilities between children with CIs and children with NH gradually closed. While at the initial five to six assessments (3 to 36 months after implantation), significant differences between children with CIs and children with NH were observed; at 4 years after implantation, there were no longer any significant group differences in general language skills and most children with CIs achieved scores within 1 SD of the tests' normative means. From 2 to 3 years after implantation onward, expressive vocabulary and receptive grammar skills of children with CIs were similar to those of the reference group. However, from 4 years after implantation until the end of the observation period, 6 years after implantation, expressive grammar skills of children with CIs were lower than those of children with NH. In addition, a gap in receptive vocabulary appeared and grew increasingly larger from 4 to 6 years postimplantation. At the final assessment, the children with CIs had an average receptive vocabulary score around 1 SD below the normative mean. Regression analysis indicated that the children's language outcomes at 6 years after implantation were related to their speech recognition skills, age at CI activation, and maternal education. CONCLUSIONS: In the first 4 years after implantation, the language performance of children with CIs became increasingly similar to that of their NH peers. However, between 4 and 6 years after implantation, there were indications of challenges with certain aspects of language, specifically receptive vocabulary and expressive grammar. Because these challenges first appeared after the 4-year assessment, the findings underline the importance of long-term language intervention to increase the chances of a continued language development comparable to that of NH peers. They also indicate that there is a need for comprehensive longitudinal studies of the language development of children with CIs beyond 4 years after implantation.

ABSTRACT

OBJECTIVES: The objective of this study was to assess self-reported health-related quality of life (HR-QOL) in a group of children with cochlear implants (CIs) and to compare their scores to age- and gender-matched controls. The authors also assessed the agreement between proxy- and self-reported HR-QOL in the CI group and examined individual and environmental variables that could be associated with higher or lower self-reported HR-QOL in the CI group. DESIGN: The sample consisted of 168 children between the ages of 5;6 and 13;1 (years;months), where 84 children had CIs (CI group) and 84 were age- and gender-matched controls with normal hearing (NH group). HR-QOL was assessed with the generic questionnaire Pediatric Quality of Life Inventory. Parents of the children in the CI group completed the same questionnaire as the children. In addition, the children in the CI group completed tests of language, hearing, and nonverbal I.Q. and background variables such as age at implantation and socioeconomic status were assessed. RESULTS: On average, children with CIs rated their HR-QOL lower than peers with normal hearing on school functioning, social functioning, and overall HR-QOL. A higher percentage of children with CIs reported low levels of HR-QOL than did those in the NH group, 27% and 12%, respectively. The differences between groups were small, and fewer children than parents reported concerningly low HR-QOLs. Better spoken-language skills and older age at the time of testing was associated with better HR-QOL. CONCLUSIONS: Most children with CIs in this study reported HR-QOLs that were close to those of their age- and gender-matched normal-hearing peers. The children, however, reported concerns about social and school functioning, indicating that these areas require more attention to ensure children with CIs have good HR-QOL. Improving spoken-language skills in children with CIs may contribute to improved HR-QOL.

ABSTRACT

Children with hearing loss, and those with language disorders, can have excellent speech recognition in quiet, but still experience unique challenges when listening to speech in noisy environments. However, little is known about how speech-in-noise (SiN) perception relates to individual differences in cognitive and linguistic abilities in these children. The present study used the Norwegian version of the Hearing in Noise Test (HINT) to investigate SiN perception in 175 children aged 5.5-12.9 years, including children with cochlear implants (CI, n = 64), hearing aids (HA, n = 37), developmental language disorder (DLD, n = 16) and typical development (TD, n = 58). Further, the study examined whether general language ability, verbal memory span, non-verbal IQ and speech perception of monosyllables and sentences in quiet were predictors of performance on the HINT. To allow comparisons across ages, scores derived from age-based norms were used for the HINT and the tests of language and cognition. There were significant differences in SiN perception between all the groups except between the HA and DLD groups, with the CI group requiring the highest signal-to-noise ratios (i.e., poorest performance) and the TD group requiring the lowest signal-to-noise ratios. For the full sample, language ability explained significant variance in HINT performance beyond speech perception in quiet. Follow-up analyses for the separate groups revealed that language ability was a significant predictor of HINT performance for children with CI, HA, and DLD, but not for children with TD. Memory span and IQ did not predict variance in SiN perception when language ability and speech perception in quiet were taken into account. The finding of a robust relation between SiN perception and general language skills in all three clinical groups call for further investigation into the mechanisms that underlie this association.

ABSTRACT

Although the majority of early implanted, profoundly deaf children with cochlear implants (CIs), will develop correct pronunciation if they receive adequate oral language stimulation, many of them have difficulties with perceiving minute details of speech. The main aim of this study is to measure the confusion of consonants and vowels in well-performing children and adolescents with CIs. The study also aims to investigate how age at onset of severe to profound deafness influences perception. The participants are 36 children and adolescents with CIs (18 girls), with a mean (SD) age of 11.6 (3.0) years (range: 5.9-16.0 years). Twenty-nine of them are prelingually deaf and seven are postlingually deaf. Two reference groups of normal-hearing (NH) 6- and 13-year-olds are included. Consonant and vowel perception is measured by repetition of 16 bisyllabic vowel-consonant-vowel nonsense words and nine monosyllabic consonant-vowel-consonant nonsense words in an open-set design. For the participants with CIs, consonants were mostly confused with consonants with the same voicing and manner, and the mean (SD) voiced consonant repetition score, 63.9 (10.6)%, was considerably lower than the mean (SD) unvoiced consonant score, 76.9 (9.3)%. There was a devoicing bias for the stops; unvoiced stops were confused with other unvoiced stops and not with voiced stops, and voiced stops were confused with both unvoiced stops and other voiced stops. The mean (SD) vowel repetition score was 85.2 (10.6)% and there was a bias in the confusions of [i:] and [y:]; [y:] was perceived as [i:] twice as often as [y:] was repeated correctly. Subgroup analyses showed no statistically significant differences between the consonant scores for pre- and postlingually deaf participants. For the NH participants, the consonant repetition scores were substantially higher and the difference between voiced and unvoiced consonant repetition scores considerably lower than for the participants with CIs. The participants with CIs obtained scores close to ceiling on vowels and real-word monosyllables, but their perception was substantially lower for voiced consonants. This may partly be related to limitations in the CI technology for the transmission of low-frequency sounds, such as insertion depth of the electrode and ability to convey temporal information.

ABSTRACT

Purpose: The study compared how parents of children with cochlear implants (CIs) and parents of children with normal hearing perceive their children's health-related quality of life (HR-QOL). Method: The sample consisted of 186 Norwegian-speaking children in the age span of 5;0-12;11 (years;months): 106 children with CIs (53% boys, 47% girls) and 80 children with normal hearing (44% boys, 56% girls). No children had known additional disabilities affecting language, cognitive development, or HR-QOL. Parents completed the generic questionnaire Pediatric Quality of Life Inventory (Varni, Seid, & Kurtin, 2001), whereas children completed a test battery measuring different aspects of language and hearing. Results: Parents of children with CIs reported statistically significantly poorer HR-QOL in their children, on Pediatric Quality of Life Inventory total score and the subdomains social functioning and school functioning. Roughly 50% of parents of children with CIs reported HR-QOL levels (total score) within normal limits. No significant differences between groups emerged on the physical health and emotional functioning subscales. For the children in the group with CIs, better speech perception in everyday situations was associated with higher proxy-ratings of HR-QOL. Better spoken language skills were weakly to moderately associated with higher HR-QOL. Conclusions: The findings suggest that the social and school situation is not yet resolved satisfactorily for children with CIs. Habilitation focusing on spoken language skills and better sound environment may improve social interactions with peers and overall school functioning.

ABSTRACT

Purpose: The purpose of this systematic review and meta-analysis was to establish a baseline of the vowel and consonant identification scores in prelingually and postlingually deaf users of multichannel cochlear implants (CIs) tested with consonant-vowel-consonant and vowel-consonant-vowel nonsense syllables. Method: Six electronic databases were searched for peer-reviewed articles reporting consonant and vowel identification scores in CI users measured by nonsense words. Relevant studies were independently assessed and screened by 2 reviewers. Consonant and vowel identification scores were presented in forest plots and compared between studies in a meta-analysis. Results: Forty-seven articles with 50 studies, including 647 participants, thereof 581 postlingually deaf and 66 prelingually deaf, met the inclusion criteria of this study. The mean performance on vowel identification tasks for the postlingually deaf CI users was 76.8% (N = 5), which was higher than the mean performance for the prelingually deaf CI users (67.7%; N = 1). The mean performance on consonant identification tasks for the postlingually deaf CI users was higher (58.4%; N = 44) than for the prelingually deaf CI users (46.7%; N = 6). The most common consonant confusions were found between those with same manner of articulation (/k/ as /t/, /m/ as /n/, and /p/ as /t/). Conclusions: The mean performance on consonant identification tasks for the prelingually and postlingually deaf CI users was found. There were no statistically significant differences between the scores for prelingually and postlingually deaf CI users. The consonants that were incorrectly identified were typically confused with other consonants with the same acoustic properties, namely, voicing, duration, nasality, and silent gaps. A univariate metaregression model, although not statistically significant, indicated that duration of implant use in postlingually deaf adults predict a substantial portion of their consonant identification ability. As there is no ceiling effect, a nonsense syllable identification test may be a useful addition to the standard test battery in audiology clinics when assessing the speech perception of CI users.

ABSTRACT

To understand the interaction between sensory experiences and cognition, it is critical to investigate the possibility that deprivation in one sensory modality might affect cognition in other modalities. Here we are concerned with the hypothesis that early experience with sound is vital to the development of domain-general sequential processing skills. In line with this hypothesis, a seminal empirical study found that prelingually deaf children had impaired sequence learning in the visual modality. In order to assess the limits of this hypothesis, the current study employed a different visual sequence learning task in an investigation of prelingually deaf children with cochlear implants and normal hearing children. Results showed statistically significant learning in each of the two groups, and no significant difference in the amount of learning between groups. Moreover, there was no association between the age at which the child received their implant (and thus access to electric hearing) and their performance on the sequential learning task. We discuss key differences between our study and the previous study, and argue that the field must reconsider claims about domain-general cognitive impairment resulting from early auditory deprivation.

ABSTRACT

OBJECTIVES: To explore the impact of parental ethnicity on cochlear implantation in children in Norway with regard to incidence rates of cochlear implants (CIs), comorbidies, age at onset of profound deafness (AOD), age at first implantation, uni- or bilateral CI, and speech recognition. METHOD: This retrospective cohort study included all children (N = 278) aged <18 years in Norway who received their first CI during the years 2004-2010. RESULTS: 86 children (30.9%) in our study sample had parents of non-Nordic ethnicity, of whom 46 were born in Nordic countries with two non-Nordic parents. Compared with the background population, children with non-Nordic parents were 1.9 times more likely to have received CI than Nordic children (i.e., born in Nordic countries with Nordic parents). When looking at AOD, uni-vs. bilateral CIs, and comorbidities, no significant differences were found between Nordic children and children with a non-Nordic ethnicity. Among children with AOD <1 year (n = 153), those born in non-Nordic countries with two non-Nordic parents (n = 6) and adopted non-Nordic children (n = 6) received their first CI on average 14.9 and 21.1 months later than Nordic children (n = 104), respectively (p = 0.006 and 0.005). Among children with AOD <1 year, those born in Nordic countries with two non-Nordic parents (n = 31) received their CI at an older age than Nordic children, but this difference was not significant after adjusting for calendar year of implantation and excluding comorbidity as a potential cause of delayed implantation. The mean age at implantation for children with AOD <1 year dropped 2.3 months/year over the study period. The mean monosyllable speech recognition score was 84.7% for Nordic children and 76.3% for children born in Norway with two non-Nordic parents (p = 0.002). CONCLUSIONS: The incidence of CI was significantly higher in children with a non-Nordic vs. a Nordic ethnicity, reflecting a higher incidence of profound deafness. Children born in Norway have equal access to CIs regardless of their ethnicity, but despite being born and receiving care in Norway, prelingually deaf children with non-Nordic parents are at risk of receiving CI later than Nordic children. Moreover, prelingually deaf children who arrive in Norway at an older age may be at risk for a worse prognosis after receiving a CI due to lack of auditory stimulation in early childhood, which is critical for language development and late implantation; this is a serious issue with regard to deafness among refugees.

ABSTRACT

Treatment programs based on a neurophysiological model have shown a positive effect on anxiety and depression in tinnitus patients. The aim of this paper was to assess the long-term effect of tinnitus habituation therapy. Sixty-eight individuals were treated with a comprehensive therapy program. The degree of anxiety and depression was assessed before, after, and five years after intervention using the Hospital Anxiety and Depression Scale. The positive and significant changes achieved after habituation therapy (pre = 1.10, post = 0.92 for anxiety and pre = 0.77, post = 0.62 for depression) were maintained five years after treatment ended (0.87 for anxiety and 0.52 for depression). A regression analysis revealed that individual evaluation of the treatment lectures, self-reported health condition, individual experiences of hyperacusis, and hearing loss could explain 44.3% of the variation in anxiety and 30.5% of the variation in depression posttreatment. Five years after, individual evaluation of the treatment lectures and self-reported health condition explained 22.2% of the variation in anxiety. These factors and individual experiences of hyperacusis could further explain 34.9% of the variation in depression. The effect of a neurophysiologic-based management treatment was maintained five years after treatment ended, indicating that the patients continued the improvement process without becoming dependent on professionals.

ABSTRACT

The objectives of the study were to describe the characteristics of the first 79 prelingually deaf cochlear implant users in Norway and to investigate to what degree the variation in speech recognition, speech- recognition growth rate, and speech production could be explained by the characteristics of the child, the cochlear implant, the family, and the educational setting. Data gathered longitudinally were analysed using descriptive statistics, multiple regression, and growth-curve analysis. The results show that more than 50% of the variation could be explained by these characteristics. Daily user-time, non-verbal intelligence, mode of communication, length of CI experience, and educational placement had the highest effect on the outcome. The results also indicate that children educated in a bilingual approach to education have better speech perception and faster speech perception growth rate with increased focus on spoken language.
