Effects of maternal sensitivity and cognitive and linguistic stimulation on cochlear implant users' language development over four years

Vocabulary Composition Shapes Language Development in Children With Cochlear Implants

Although vocabulary size is thought to index children's language abilities, an increasing body of work suggests that regularities in children's vocabulary composition, particularly the proportion of shape-based nouns (e.g., cup), support language development. Here we examine initial vocabulary composition in children with hearing loss following cochlear implantation (n = 163) and age-matched children with normal hearing (n = 87). This comparison constitutes an experiment in nature for understanding how early vocabulary composition shapes subsequent language development in the context of the clinical provision of auditory experience. Children with higher initial proportions of shape-based nouns had larger vocabularies and scored higher on tests of receptive and expressive language abilities at 1, 2, and 3 years follow-up, than children whose vocabularies had lower proportions of shape-based nouns. These effects were strongest for cochlear implant users, especially 2-3 years postimplantation. The results suggest that knowing shape-based nouns facilitates language development and may ameliorate delayed language development trajectories.

Challenging the "norm": a critical look at deaf-hearing comparison studies in research

This study critically examines the biases and methodological shortcomings in studies comparing deaf and hearing populations, demonstrating their implications for both the reliability and ethics of research in deaf education. Upon reviewing the 20 most-cited deaf-hearing comparison studies, we identified recurring fallacies such as the presumption of hearing ideological biases, the use of heterogeneously small samples, and the misinterpretation of critical variables. Our research reveals a propensity to based conclusions based on the norms of white, hearing, monolingual English speakers. This dependence upholds eugenics ideas and scientific ableism, which reinforces current power dynamics that marginalize the epistemologies and lived experiences of deaf populations. Going forward, it will be imperative for deaf people to be included in meaningful roles in deaf-related research as active contributors who help define the whole research process. Without this shift, the research risks remaining detached from the very populations it seeks to understand.

Factors affecting consonant production accuracy in children with cochlear implants: Expressive vocabulary and maternal education

BACKGROUND

Despite the ability of cochlear implants (CIs) to provide children with access to speech, there is considerable variability in spoken language outcomes. Research aimed at identifying factors influencing speech production accuracy is needed.

AIMS

To characterize the consonant production accuracy of children with cochlear implants (CWCI) and an age-matched group of children with typical hearing (CWTH) and to explore several factors that potentially affect the ability of both groups to accurately produce consonants.

METHODS & PROCEDURES

We administered the Bankson-Bernthal Test of Phonology (BBTOP) to a group of 25 CWCI (mean age = 4;9, SD = 1;6, range = 3;2-8;5) implanted prior to 30 months of age with a mean duration of implant usage of 3;6 and an age-matched group of 25 CWTH (mean age = 5;0, SD = 1;6, range = 3;1-8;6). The recorded results were transcribed, and the accuracy of the target consonants was determined. Expressive vocabulary size estimates were obtained from a language sample using the number of different words (NDW). A parent questionnaire provided information about maternal education, duration of CIs experience and other demographic characteristics of each child.

OUTCOMES & RESULTS

The CWCI group demonstrated some similarities to, and some differences from, their hearing peers. The CWCI demonstrated poorer consonant production accuracy overall and in various phonetic categories and word positions. However, both groups produced initial consonants more accurately than final consonants. Whilst CWCI had poorer production accuracy than CWTH for all phonetic categories (stops, nasals, fricatives, affricates, liquids and glides and consonant clusters), both groups exhibited similar error patterns across categories. For CWCI, the factors most related to consonant production accuracy when considered individually were expressive vocabulary size, followed by duration of CI experience, chronological age, maternal education and gender. The combination of maternal education and vocabulary size resulted in the best model of consonant production accuracy for this group. For the CWTH, chronological age followed by vocabulary size were most related to consonant production accuracy. No combination of factors yielded an improved model for the CWTH.

CONCLUSIONS & IMPLICATIONS

Whilst group differences in production accuracy between the CWCI and CWTH were found, the pattern of errors was similar for the two groups of children, suggesting that the children are at earlier stages of overall consonant production development. Although duration of CI experience was a significant covariate in a single-variable model of consonant production accuracy for CWCI, the best multivariate model of consonant production accuracy for these children was based on the combination of expressive vocabulary size and maternal education.

WHAT THIS PAPER ADDS

What is already known on the subject Research has shown that a range of factors is associated with consonant production accuracy by CWCIs, including factors such as the age at implant, duration of implant use, gender, other language skills and maternal education. Despite numerous studies that have examined speech sound production in these children, most have explored a limited number of factors that might explain the variability in scores obtained. Research that examines the potential role of a range of child-related and environmental factors in the same children is needed to determine the predictive role of these factors in speech production outcomes. What this paper adds to the existing knowledge Whilst the consonant production accuracy was lower for the CWCIs than for their typically hearing peers, there were some similarities suggesting that these children are experiencing similar, but delayed, acquisition of consonant production skills to that of their hearing peers. Whilst several factors are predictive of consonant production accuracy in children with implants, vocabulary diversity and maternal education, an indirect measure of socio-economic status, were the best combined predictors of consonant production accuracy. What are the potential or actual clinical implications of this work? Understanding the factors that shape individual differences in CWCI speech production is important for effective clinical decision-making and intervention planning. The present findings point to two potentially important factors related to speech sound production beyond the duration of robust hearing in CWCI, namely, a lexical diversity and maternal education. This suggests that intervention is likely most efficient that addresses both vocabulary development and speech sound development together. The current findings further suggest the importance of parental involvement and commitment to spoken language development and the importance of receiving early and consistent intervention aimed both at skill development and parental efficacy.

Early assessment of communicative competence in children with hearing loss using the Child-Caregiver Communication Assessment through Rebesco's Evaluation (CC-CARE) method

PURPOSE

This work presents a new frame-by-frame video analysis method called Child-Caregiver Communication Assessment through Rebesco's Evaluation (CC-CARE), developed in the context of pediatric hearing loss as a rehabilitation tool for assessing children's early communication skills. CC-CARE stems from the commonly used Tait video analysis and extends it by including a new set of parameters aimed at disentangling between hearing-dependent and hearing-independent aspects of communication.

METHOD

In this paper, we collected video samples of child-caregiver interactions in a group of 65 normal-hearing children and a group of 165 hearing-impaired children. For each group, we present the CC-CARE method and describe the parameters, their score distributions, correlations and we estimate the adherence of the CC-CARE scores with children's developmental trajectory. Moreover, we compare the results of CC-CARE scores between the two groups having had different development of the auditory system. Finally, a fully-data driven approach was employed to assess the consistency of the communicative efficacy index (CEI), a score aiming to capture a global result of the CC-CARE procedure.

RESULTS

Correlations among parameter scores were found in each within-group analysis, revealing CC-CARE's internal consistency in measuring associated but nonoverlapping communication dimensions. For both groups, CC-CARE scores were associated with participants' age. Differences between scores emerged for a between-group analysis, indicating CC-CARE sensitivity to extract communication differences as a function of the hearing status. For both groups, the data analysis revealed that the CEI captures large variance portions across all parameter scores of the CC-CARE method.

CONCLUSIONS

Results provide the first evidence that the CC-CARE video analysis method could be a reliable tool capable of highlighting the cascading effects of hearing impairment on children's preverbal communicative efficacy. The CC-CARE method aims to support early rehabilitation of hearing loss by describing a child's communicative efficacy.

Two are better than one: Differences in cortical EEG patterns during auditory and visual verbal working memory processing between Unilateral and Bilateral Cochlear Implanted children

Despite the proven effectiveness of cochlear implant (CI) in the hearing restoration of deaf or hard-of-hearing (DHH) children, to date, extreme variability in verbal working memory (VWM) abilities is observed in both unilateral and bilateral CI user children (CIs). Although clinical experience has long observed deficits in this fundamental executive function in CIs, the cause to date is still unknown. Here, we have set out to investigate differences in brain functioning regarding the impact of monaural and binaural listening in CIs compared with normal hearing (NH) peers during a three-level difficulty n-back task undertaken in two sensory modalities (auditory and visual). The objective of this pioneering study was to identify electroencephalographic (EEG) marker pattern differences in visual and auditory VWM performances in CIs compared to NH peers and possible differences between unilateral cochlear implant (UCI) and bilateral cochlear implant (BCI) users. The main results revealed differences in theta and gamma EEG bands. Compared with hearing controls and BCIs, UCIs showed hypoactivation of theta in the frontal area during the most complex condition of the auditory task and a correlation of the same activation with VWM performance. Hypoactivation in theta was also observed, again for UCIs, in the left hemisphere when compared to BCIs and in the gamma band in UCIs compared to both BCIs and NHs. For the latter two, a correlation was found between left hemispheric gamma oscillation and performance in the audio task. These findings, discussed in the light of recent research, suggest that unilateral CI is deficient in supporting auditory VWM in DHH. At the same time, bilateral CI would allow the DHH child to approach the VWM benchmark for NH children. The present study suggests the possible effectiveness of EEG in supporting, through a targeted approach, the diagnosis and rehabilitation of VWM in DHH children.

Early-stage use of hearing aids preserves auditory cortical structure in children with sensorineural hearing loss

Hearing is critical to spoken language, cognitive, and social development. Little is known about how early auditory experiences impact the brain structure of children with bilateral sensorineural hearing loss. This study examined the influence of hearing aid use and residual hearing on the auditory cortex of children with severe to profound congenital sensorineural hearing loss. We evaluated cortical preservation in 103 young pediatric cochlear implant candidates (55 females and 48 males) by comparing their multivoxel pattern similarity of auditory cortical structure with that of 78 age-matched children with typical hearing. The results demonstrated that early-stage hearing aid use preserved the auditory cortex of children with bilateral congenital sensorineural hearing loss. Children with less residual hearing experienced a more pronounced advantage from hearing aid use. However, this beneficial effect gradually diminished after 17 months of hearing aid use. These findings support timely fitting of hearing aids in conjunction with early implantation to take advantage of neural preservation to maximize auditory and spoken language development.

Current Issues With Pediatric Cochlear Implantation

Cochlear implants (CIs) have demonstrated a clear functional benefit in children with severe-to-profound sensorineural hearing loss (SNHL) and thus have gained wide acceptance for treating deafness in the pediatric population. When evaluating young children for cochlear implantation, there are unique considerations beyond the standard issues addressed during surgery in adults. Because of advances in genetic testing, imaging resolution, CI technology, post-implant rehabilitation, and other factors, issues related to CI surgery in children continue to evolve. Such factors have led to changes in candidacy guidelines, vaccine requirements, and lowering of age requirement for surgery. In addition, differences in the anatomy and physiology of infants require special attention to ensure safety when operating on young children. This review summarizes these issues and provides guidance for surgeons treating children with SNHL.

Family-Centered Early Intervention Deaf/Hard of Hearing (FCEI-DHH): Support Principles

This article is the sixth in a series of eight articles that comprise a special issue on Family-Centered Early Intervention (FCEI) for children who are deaf or hard of hearing (DHH) and their families, or FCEI-DHH. The Support Principles article is the second of three articles that describe the 10 Principles of FCEI-DHH, preceded by the Foundation Principles, and followed by the Structure Principles, all in this special issue. The Support Principles are composed of four Principles (Principles 3, 4, 5, and 6) that highlight (a) the importance of a variety of supports for families raising children who are DHH; (b) the need to attend to and ensure the well-being of all children who are DHH; (c) the necessity of building the language and communication abilities of children who are DHH and their family members; and (d) the importance of considering the family's strengths, needs, and values in decision-making.

The timeline of non-vocal and vocal communicative skills in infants with hearing loss

Objective

The study investigates what is the link between early verbal and non-vocal abilities, when does predominantly verbal communicative style occur after the intervention with cochlear implants (CI) or hearing aids (HA), and how predictive it is of later linguistic development in deaf and hard of hearing (DHH) infants and children.

Methods

Cohort: children with moderate-to-profound hearing impairment (N = 49, 20 girls, mean age at HA or CI intervention = 15 months, range: 4-35 months).

Measures

Receptive and productive vocabulary at 24 and 36 months and video analysis at 12 months post-intervention. Analysis: Predictive values of total and verbal responses to communicative turns for later vocabulary development were assessed, as well as the relative time course of the development of vocal/verbal communication in DHH children.

Results

Vocabulary at 24 months is predicted by auditory responses at 12 months, as well as by overall responsiveness before intervention. Non-vocal responses decline and overall verbal responses increase significantly between 6 and 12 months after intervention. The trend is delayed in children with delayed (>12 months of age) treatment with CI or HA.

Conclusions

Age of intervention affects the development of vocal/verbal communicative style. Language development, in particular, vocabulary growth, can be further stimulated by the enhancement of preverbal (both vocal and non-vocal) communicative skills.

Teaching Caregivers to Implement the Caregivers Optimizing Achievement of Children With Hearing Loss (COACH) Intervention

PURPOSE

This study examined the effectiveness of Caregivers Optimizing Achievement of Children With Hearing Loss (COACH), an intervention in which parents were taught naturalistic interaction strategies that addressed the unique linguistic input needs of their young children with hearing loss.

METHOD

A single-subject multiple-baseline across-behaviors design was used with four caregiver-child dyads to determine the effects of COACH training on caregivers' use of the COACH language facilitation strategies and on their children's language abilities.

RESULTS

A functional relation was demonstrated between teaching of strategies and caregivers' use of the strategies across three dyads with slower, consistent changes observed in a fourth dyad. Improvements in children's use of target-level language were observed for children in three dyads.

CONCLUSIONS

Caregivers were able to implement COACH language facilitation strategies, although the pace of caregivers' learning differed across dyads. Caregivers reported high satisfaction with participating in the intervention. Future research using a randomized design and a longer intervention condition is needed for a more complete assessment of the effects of the intervention on children's language abilities.

Parents of children with hearing loss: Impact and exposure of COVID-19 on mental health

The aim of this study was to evaluate the impact and exposure of COVID-19 on parent mental health (e.g., depression, anxiety, and post-traumatic stress disorder (PTSD), for parents of children with hearing loss. The survey was distributed via an electronic survey to families subscribed to a pediatric program listserv as part of a university medical center. Fifty-five percent of parents reported elevated symptoms of anxiety, while 16% scored in the clinically significant range for depression. In addition, 20% of parents reported elevated symptoms of PTSD. Liner regressions found that impact of COVID-19 predicted anxiety symptoms, while both impact and exposure predicted depression and PTSD symptoms. In addition, both impact and exposure predicted COVID related parental distress. Exposure and impact of COVID-19 has had negative consequences on parents of children with hearing loss. Although exposure influenced parental mental health, impact uniquely affected depression and PTSD. Results highlight the need for mental health screening, as well implementation of psychological interventions using telehealth or in-person consultations. Future work should focus on post-pandemic challenges, including long-term psychological functioning due to the established relationship between parental mental health and pediatric outcomes.

Language and academic outcomes of children with cochlear implants in an inclusive setting: Evidence from 18 years of data

OBJECTIVE

This study examined outcomes in core and pragmatic language, receptive vocabulary, and academic skills in children with cochlear implants (CIs) enrolled in an inclusive educational setting.

METHODS

Eighty-eight children with CIs were included in the analyses. Data was collected over an 18-year period, at six-month intervals for core language, vocabulary, and pragmatic skills and in kindergarten and second grade for academic skills. Kaplan-Meier analyses were used to estimate the median time to achieve age-appropriate scores.

RESULTS

Results indicated the median time to obtain age-appropriate skills for children with CIs enrolled in our program was less than three years for core language and pragmatic skills and less than two years for vocabulary. Over 90% of the sample had academic skills in the average range in both kindergarten and second grade.

DISCUSSION

This study shares outcomes of children with CIs who received consistent and intensive transdisciplinary intervention in an inclusive educational setting, revealing the trajectory required to obtain age-appropriate skills, when compared to normative data.

CONCLUSION

Results were favorable, indicating that children with CIs in an inclusive program, with intensive intervention and strong language and social models, can develop skills commensurate with typically developing peers across a variety of core skills.

Assessing parent interaction with deaf infants: A quantitative survey of UK professional practice

BACKGROUND

Between 90% and 95% of deaf children are born to hearing parents who often need support with how to adapt their communication. Parent-child interaction (PCI) is an important predictor of deaf children's future language development. It is therefore necessary for professionals to assess parents' strengths and needs to identify areas for intervention. Qualified teachers of the deaf (QToDs), speech and language therapists (SLTs), psychologists, and national deaf child and adolescent mental health (NDCAMHS) professionals regularly support families with deaf children. With no current evidence-based tool available to assist with the assessment of PCI in deafness, it is important to gather information on current professional practice as this may differ from known practices within research.

AIMS

To survey the practices of UK-based professionals in the assessment of PCI where the deaf infant is aged 0-3 years. Professionals were QToDs, SLTs, psychologists or psychiatrists and professionals working at NDCAMHS services.

METHODS & PROCEDURES

After a pilot phase, an 85-item survey was distributed electronically through a range of professional and social media networks. Survey items were based on a systematic review of PCI with deaf infants. Survey questions were focused on parent behaviours that were assessed, methods of assessment, goal planning and service provision. Analysis was conducted using descriptive and inferential statistics.

OUTCOMES & RESULTS

A total of 190 professionals from across the UK completed part 1 of the survey; this decreased to 148 in part 4. Respondents were primarily female, hearing, used spoken English and had 16 years or more experience. Results indicate that PCI is routinely assessed by a large proportion of professionals and there is a substantial overlap in which parent behaviours are assessed. Some parent behaviours are assessed that do not feature in the research. Methods of assessment are informal and predominantly consist of observation and note making, with professionals using their own skills and experience to analyse interaction. Goal setting practices were largely similar between professionals, with many jointly deciding goals with parents.

CONCLUSIONS & IMPLICATIONS

This survey highlights the range of parent behaviours assessed by UK professionals in PCI with deaf children aged 0-3. This survey provides valuable information about and for professionals who assess PCI and set intervention goals with parents. Information from research and professional practice is important to consider in the design of a future PCI assessment. Implications are included for future research in this area.

WHAT THIS PAPER ADDS

What is already known on this subject Parental involvement is one of the greatest predictors of deaf children's language outcomes. With many deaf children born to hearing parents, parents often need guidance with how to facilitate effective communication. A recent systematic review identified the range of parent behaviours and methods used to analyse PCI in international research studies, but little evidence or guidance exists on how professionals assess this phenomenon in practice. What this study adds This is the first survey to generate large, valuable practice-based evidence for the assessment of parents' communication behaviours as they interact with their deaf infants aged 0-3. The survey recruited a range of multidisciplinary professionals working on interaction within this field: SLTs, qualified teachers of the deaf, psychologists or psychiatrists, and professionals working within deaf child and adolescent mental health services. The study reports on which behaviours these professionals assess and how, and includes information on the goal setting behaviours of practitioners. Most respondents were highly experienced; the survey, therefore, reveals expert practice within the field. What are the potential or actual clinical implications of this work? We recommend the following practice: (1) incorporate a range of parent-based behaviours in PCI assessments, including establishing joint engagement and parental sensitivity, as well as communication-focused behaviours; (2) video record PCI assessments where possible to enable professionals and parents to watch and reflect together; (3) following assessment, set parent-focused goals in collaboration with families, ensuring parents' skills, particularly their strengths, are considered. All primary caregivers should be included in the process where possible; and (4) reassess PCI regularly (at least termly) to monitor and encourage families' progress. The timing of reviews should be discussed between parent and professional.

Impact of Sociodemographic Disparities on Language Outcomes After Cochlear Implantation in a Diverse Pediatric Cohort

OBJECTIVE

We examined how sociodemographic and audiologic factors affect receptive and expressive language outcomes in children with cochlear implantation.

STUDY DESIGN

Retrospective cohort study.

SETTING

A hearing loss (HL) clinic at a tertiary center.

METHODS

Sociodemographic variables, HL characteristics, age at implantation, and receptive language scores (Preschool Language Scale and the Clinical Evaluation of Language Fundamentals) were collected from patients with congenital HL who received their first implant by 4 years old after January 1, 2007. t Tests, linear regression, Mann-Whitney, Cohen's d, and mediation analysis were used for descriptive statistics and hypothesis testing.

RESULTS

Among 79 patients, 42 (53%) were females, 44 (56%) under-represented minorities, and 56 (71%) had public insurance. At least 1 year after implantation, the median receptive language score was 69 (range 50-117). Females (p = .005), having private insurance (p = .00001), having a Cochlear Implant Profile score below 4 (p = .0001), and receiving their implant at or before 12 months of age (p = .0009) were significantly associated with improved receptive language outcomes. Insurance type had a significant effect on receptive language outcomes, independent from age at first implantation (total effect: coef = -13.00, p = .02; direct effect: coef = -12.26, p = .03; indirect effect: coef = -0.75, p = .47). Sociodemographic variables had large effect sizes, with the Cochlear Implant Profile score having the largest effect size (d = 1.3).

CONCLUSION

Sociodemographic factors have a large impact on receptive language outcomes. Public insurance is associated with worse receptive language, not mediated by later age at implantation, suggesting that other factors primarily impact language outcomes in publicly insured children with cochlear implants.

The influence of auditory selective attention on linguistic outcomes in deaf and hard of hearing children with cochlear implants

PURPOSE

Auditory selective attention (ASA) is crucial to focus on significant auditory stimuli without being distracted by irrelevant auditory signals and plays an important role in language development. The present study aimed to investigate the unique contribution of ASA to the linguistic levels achieved by a group of cochlear implanted (CI) children.

METHODS

Thirty-four CI children with a median age of 10.05 years were tested using both the "Batteria per la Valutazione dell'Attenzione Uditiva e della Memoria di Lavoro Fonologica nell'età evolutiva-VAUM-ELF" to assess their ASA skills, and two Italian standardized tests to measure lexical and morphosyntactic skills. A regression analysis, including demographic and audiological variables, was conducted to assess the unique contribution of ASA to language skills.

RESULTS

The percentages of CI children with adequate ASA performances ranged from 50 to 29.4%. Bilateral CI children performed better than their monolateral peers. ASA skills contributed significantly to linguistic skills, accounting alone for the 25% of the observed variance.

CONCLUSIONS

The present findings are clinically relevant as they highlight the importance to assess ASA skills as early as possible, reflecting their important role in language development. Using simple clinical tools, ASA skills could be studied at early developmental stages. This may provide additional information to outcomes from traditional auditory tests and may allow us to implement specific training programs that could positively contribute to the development of neural mechanisms of ASA and, consequently, induce improvements in language skills.

Psychosocial Impact of the COVID-19 Pandemic on Children With Cochlear Implants and Their Parents/Family Members

Purpose:

The purpose of this study was to describe hearing health care and education experiences of children with cochlear implants (CIs) during the COVID-19 pandemic and the potential psychosocial effects of the pandemic on these children and their parents/family members.

Method:

The study used a cross-sectional survey design. The study sample comprised two groups, namely, parents/family members of children with CIs (study group, n = 70, M age = 44.6 ± 12.4 years) and parents/family members of children with normal hearing (control group, n = 58, M age = 43.8 ± 11.5 years). Parents/family members completed the Perceived Stress Scale (PSS), the Coronavirus Anxiety Scale (CAS), and the Family Perspective Profile form, as well as the Demographic Information form.

Results:

The PSS scores of the study group were higher than those of the control group ( p = .001). However, there was no statistically significant difference between groups in the CAS scores ( p = .896). According to the Family Perspective Profile form, almost half of the parents/family members of children with CIs reported that their children experienced difficulties in education and hearing health care services during the pandemic and showed some changes in their attitudes and behaviors.

Conclusions:

During the pandemic, the stress levels of parents/family members of children with CIs were higher than parents/family members of children with normal hearing. In addition to the challenges posed by the pandemic, the difficulties that parents/family members of children with CIs experience in meeting their children's additional needs related to accessing education and hearing health care services may have contributed to increased stress levels.

Parent-reported quality of life in children with cochlear implants differs across countries

Pediatric cochlear implantation affects communication skills and quality of life, specifically how children interact with others and feel about themselves. Numerous studies worldwide examine well-being among pediatric cochlear implant users, but none to date compare condition-specific quality of life across countries. This retrospective study compares parent-reported cochlear implant-specific quality of life summary data across 14 published studies spanning 11 countries and 9 languages. Sample size ranged from 7 to 370 participants, and children across studies varied in mean chronologic age (3.1-12.2 years), implantation age (1.5-4.6 years), and cochlear implant experience (1.3-8.2 years). Parents completed the Children with Cochlear Implants: Parental Perspectives (CCIPP) questionnaire, an instrument assessing parent-reported cochlear implant-specific quality of life, in their home language. Analysis of variance tests were run for each CCIPP subscale across studies using summary data to determine significant differences between published manuscripts. Across countries, parents of children with cochlear implants appraise communication, social relations, and self-reliance most positively, and the effects of implantation and supporting the child least positively. Cross-country analyses revealed a significant effect of study (country) on quality of life ratings in each domain, with the largest differences in the communication domain. Limited access to implant-related accommodations, cultural awareness of hearing loss, and varying parent expectations may explain country differences in parental ratings of quality of life. Culturally sensitive psychoeducation for the entire family may foster improved life satisfaction for pediatric cochlear implant users and their families.

Assessing a Video-Based Intervention to Promote Parent Communication Strategies with a Deaf Infant: A Feasibility and Acceptability Study

Infant–parent interaction forms the foundation for language learning. For the majority of deaf infants, hearing loss can impact access to, and the quality of communicative interactions, placing language development at risk. Support for families to meet the challenges faced during interaction is highly variable in the United Kingdom. In a step towards more standardized but tailorable family support, we co-produced an instructional, video-based intervention, testing for feasibility in terms of behavior change in seven communicative strategies and acceptability with 9 parents, forming study 1. Parents increased their use of the majority of behaviors and found content and delivery acceptable. However, further development was required to: (a) support use of semantically contingent talk and attention getting strategies to elicit infant attention, and (b) ensure the information was provided in a bite-size format that could be tailored to individual families. In study 2, the intervention was refined based on findings from study 1 and assessed for acceptability with 9 parents and 17 professionals, who reported similar high acceptability scores. Final refinements and modifications could be addressed in future interventions. The current studies provide a positive early step towards a standardized intervention to support communication that could be used in routine practice.

Associations Between Paternal Play and Executive Function in Deaf and Hard of Hearing Children

PURPOSE

Responsive and dynamic aspects of father-child play are associated with behavioral and neurocognitive development in children and could represent an important contributor to executive function (EF) skills for children who are deaf and hard of hearing (DHH). This study examined associations between paternal behaviors during play and EF skills of DHH children and children with typical hearing (TH).

METHOD

Father-child dyads in families with DHH children (n = 30) and TH children (n = 29) participated in a 15-min video-recorded free-play session that was coded for parental behaviors using Parent-Child Interaction Rating Scales and Rough and Tumble Play Quality. Families also completed an age-appropriate version of the Behavior Rating Index of Executive Function as a measure of child EF.

RESULTS

DHH children were rated as having significantly more everyday difficulties with working memory than TH children. Fathers of DHH children were rated as more intrusive during play than fathers of TH children; however, there were no other differences between paternal groups on coded dimensions of father child play. Paternal respect for child autonomy was associated with fewer child difficulties with planning and organization skills and paternal play engagement was associated with fewer child EF difficulties. Moderation analyses revealed that paternal sensitivity was associated with more working memory difficulties and paternal respect for child autonomy was associated with fewer working memory difficulties for DHH children only.

CONCLUSIONS

Paternal play could be an important environmental context for DHH outcomes. Fathers supporting independent play might generally support EF. Paternal engagement in play might also benefit EF. Results highlight paternal behavioral attributes that could lead to potential father-embedded intervention models.

Development and Validation of a Parenting Stress Module for Parents of Children Using Cochlear Implants

OBJECTIVES

The purpose of this study was to develop and validate a cochlear implant (CI)-specific parenting stress measure using the FDA Guidance on Patient-Reported Outcomes (2009).

METHODS

The development and psychometric validation of the Parenting Stress-CI module for both the Early Childhood (EC; 0-5 years) and School-Age (SA; 6-12 years) versions are reported in this article. Instrument development consisted of qualitative interviews with parents of children with CIs (EC: N = 19; SA: N = 21), content analysis, item development, and cognitive testing of the instrument. Last, we conducted the psychometric validation (EC: N = 72; SA: N = 64), including analyses of internal consistency, test-retest reliability (∼2 weeks between administrations; N = 24), and convergent validity with the Parenting Stress Index-4 (PSI-4).

RESULTS

The final EC version includes 15 questions, and the SA version includes 8 questions. Both the EC and SA versions had strong reliability (EC α = .88; SA α = .85), with all items significantly correlated with the overall module (r = .43-.80). Both versions also had strong test-retest reliability (r = .99, p < .001). Last, analyses of convergent validity demonstrated significant correlations with the PSI-4 Total Stress scale for both Parenting Stress-CI versions (EC r = .66, p < .00; SA r = .45, p < .001).

CONCLUSIONS

The Parenting Stress-CI modules are reliable and valid condition-specific parenting stress instruments for parents of children with CIs ages 0-12 years, filling a significant gap in the literature. These fully validated instruments can be used to assess parental needs for support and guide the development of targeted, family centered interventions.

Assessment of Communication Abilities in Four Children with Early Bilateral CIs in Clinical and Home Environments with LENA System: A Case Report

Children’s language acquisition is underpinned by the quantity and quality of linguistic stimulation. Early diagnosis and cochlear implantation (CI), along with a family-centered intervention, are regarded as critical factors in providing appropriate language stimulation and thus supporting successful language outcomes in children with sensory neural hearing loss (SNHL). Considering the lack of tools to assess early language skills and open issues regarding the early predictors of CI outcomes, our goal was to evaluate the potential usability of the Language ENvironment Analysis (LENA) system as an early assessment and/or predictive tool. Clinical video recordings, LENA home recordings, and vocabulary scores were used to assess the progression of communication abilities of four children with CIs (6–35 m.o.). The data revealed a positive correlation between the estimated mean length of utterance (EMLU), vocal conversational turns (CT) in clinical video recordings, and receptive vocabulary, as well as the CT count in LENA being a significant predictor of productive vocabulary. These findings lead us to conclude that the LENA system has the potential to be used as an additional (tele-)measure in the early assessment of communication abilities of children with CI, as well as as a tool in the research of early predictors of CI outcomes.

Gender differences in caregiver's use of spoken language with young children who are hard-of-hearing

PURPOSE

Shared parenting among caregivers of different gender is common in the Swedish society. It is unclear if this includes shared contribution for children's language development. The objective of this cross-sectional study was to explore the natural language environment of children who were hard-of-hearing compared to typically hearing controls.

METHODS

Seventy-two families with children aged 7-35 months participated; 22 children who were hard-of-hearing (Cochlear implants, n=11; Hearing aids, n=11) and 50 controls with typical hearing. The majority of caregivers had higher education background level, especially in the control group. Families conducted a daylong recording with the Language Environment Analysis technology, when both parents were present at home. An Interpreted Time Segmental analysis was performed to extract information about female versus male caregivers quantitative word use.

RESULTS

The results showed significant gender differences related to number of adult words, with less male words than female words (p <0.001). Male caregivers of children who were hard-of-hearing contributed with around 27 % of adult words during the recordings while males in the control group contributed with 37 %. There was a larger variation in number of female words in the study group than for controls, especially in mothers of children with cochlear implants.

CONCLUSIONS

Female caregivers talk significantly more close to young children than male caregivers, and especially in the subgroup of children with cochlear implants. Children who are hard-of-hearing are dependent on a rich language environment, and might be especially vulnerable if male caregivers are less involved as language facilitators. More studies are needed to explore caregiver gender differences, both related to quantitative and qualitative language stimulation.

Receptive Vocabulary of Children With Bilateral Cochlear Implants From 3 to 16 Years of Age

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.

Multidimensional Family-Centred Early Intervention in Children with Hearing Loss: A Conceptual Model

At least two per thousand newborns are affected by hearing loss, with up to 40% with an additional disability. Early identification by universal newborn hearing screening and early intervention services are available in many countries around the world, with limited data on their effectiveness and a lack of knowledge about specific intervention-related determinants of child and family outcomes. This concept paper aimed to better understand the mechanisms by which multi-dimensional family-centred early intervention influences child outcomes, through parent behaviour, targeted by intervention by a review of the literature, primarily in the field of childhood hearing loss, supplemented by research findings on physiological and atypical child development. We present a conceptual model of influences of multi-disciplinary family-centred early intervention on family coping/functioning and parent–child interaction, with effects on child psycho-social and cognitive outcomes. Social communication and language skills are postulated as mediators between parent–child interaction and non-verbal child outcomes. Multi-disciplinary networks of professionals trained in family-centred practice and the evaluation of existing services, with respect to best practice guidelines for family-centred early intervention, are recommended. There is a need for longitudinal epidemiological studies, including specific intervention measures, family behaviours and multidimensional child outcomes.

Reciprocal Patterns of Peer Speech in Preschoolers with and without Hearing Loss

Children with hearing loss often attend inclusive preschool classrooms aimed at improving their spoken language skills. Although preschool classrooms are fertile environments for vocal interaction with peers, little is known about the dyadic processes that influence children's speech to one another and foster their language abilities and how these processes may vary in children with hearing loss. We used new objective measurement approaches to identify and quantify children's vocalizations during social contact, as determined by children's proximity and mutual orientation. The contributions of peer vocalizations to children's future vocalizations and language abilities were examined in oral language inclusion classrooms containing children with hearing loss who use hearing aids or cochlear implants and their typically hearing peers. Across over 600 hours of recorded vocal interactions of twenty-nine 2.5-3.5 year olds (16 girls) in three cohorts of children in a classroom, we found that vocalizations from each peer on a given observation predicted a child's vocalizations to that same peer on the subsequent observation. Children who produced more vocalizations to their peers had higher receptive and expressive language abilities, as measured by a standardized end-of-year language assessment. In fact, vocalizations from peers had an indirect association with end-of-year language abilities as mediated by children's vocalizations to peers. These findings did not vary as a function of hearing status. Overall, then, the results demonstrate the importance of dyadic peer vocal interactions for children's language use and abilities.

Multisensory integration and maternal sensitivity are related to each other and predictive of expressive vocabulary in 24-month-olds

Multisensory integration (MSI) is the ability to combine temporally synchronous, amodally specified sensory information to create rich, coordinated perceptual experiences. In early development, attention is directed toward such information in both social contexts (e.g., human speakers) and nonsocial contexts (e.g., multimodal toys). Parenting behaviors may support and sculpt multisensory integration by providing children with opportunities to experience amodally specified information (e.g., contingent face-to-face interactions). This study examined (a) whether 24-month-olds' MSI abilities differed as a function of context (social or nonsocial) and competition for attention (low or high), (b) whether MSI predicted expressive vocabulary, and (c) whether maternal sensitivity (MS) was related to both MSI and language. A total of 32 24-month-olds were tested in the Multisensory Attention Assessment Protocol, an audiovisual task that presents laterally positioned social/nonsocial events with and without a central distractor. Their mothers completed the MacArthur-Bates Communicative Development Inventories and participated in a free-play period with their children for MS coding. Results showed MSI in both social and nonsocial conditions (i.e., toddlers paid more attention to the "match"), but only the ability to maintain attention to the social match was related to toddlers' expressive vocabulary. In addition, MS was positively correlated with toddlers' expressive language and social MSI performance. Taken together, the pattern of results shows important relations between emerging integration abilities and parenting behavior as well as the ability of both factors to positively influence word learning during early toddlerhood.

Family Environmental Dynamics Differentially Influence Spoken Language Development in Children With and Without Hearing Loss

PURPOSE

The aim of this study was to evaluate whether families of children with sensorineural hearing loss (SNHL) are organized similarly to those of typically developing, typically hearing (TH) children and whether the dimensions of family dynamics and environment are related to spoken language development similarly in children with and without SNHL.

METHOD

Primary caregivers of children with SNHL (n = 63) or TH (n = 65) completed the Family Environment Scale-Fourth Edition (FES-4) to assess multiple dimensions of family environment. Children's receptive vocabulary was assessed with the Peabody Picture Vocabulary Test-Fourth Edition, and their receptive language was assessed by an age-appropriate version of the Concepts and Following Directions subtest of the Clinical Evaluation of Language Fundamentals and the Sentence Comprehension subscale of the Comprehensive Assessment of Spoken Language-Second Edition. Principal component analysis was used to examine the dimensional structure of the family environment.

RESULTS

Three higher order components were derived from FES-4 subscales for both families of children with SNHL and with TH: Supportive, Controlling, and Conflicted. However, the composition of the factors themselves differed between the two groups. For the TH group, most family environment measures on the FES-4 were not associated with language outcomes. In contrast, for children with SNHL, families who were more supportive, less controlling, and less conflicted had children with better language skills.

CONCLUSIONS

Three well-accepted dimensions of family dynamics and functioning apply to families of children with SNHL, but their composition differs from those of families with TH children. Family environmental dynamics were much more strongly associated with language outcomes in children with SNHL than in their TH peers. The spoken language development of children with SNHL, in particular, is better in families that provide high levels of support for each other and, in particular, low levels of control, disorganization, and conflict, reflecting the fragile nature of their spoken language development.

Association of Socioeconomic Characteristics With Receipt of Pediatric Cochlear Implantations in California

IMPORTANCE

Earlier cochlear implantation among children with bilateral severe to profound sensorineural hearing loss is associated with improved language outcomes. More work is necessary to identify patients at risk for delayed cochlear implantation and understand targets for interventions to improve cochlear implantation rates among children.

OBJECTIVE

To describe the demographics among children receiving cochlear implantations and variability in implantation rates in California and to investigate sociodemographic and parental factors associated with early pediatric cochlear implantation.

DESIGN, SETTING, AND PARTICIPANTS

This retrospective cross-sectional study was conducted using data from the Healthcare Cost and Utilization Project California State Ambulatory Surgery Database in calendar year 2018. Included patients were children aged 9 years old or younger undergoing cochlear implantation. Sociodemographic factors, location of treatment, and parental factors were collected. Data were analyzed from March through August 2021.

MAIN OUTCOMES AND MEASURES

Binary logistic regression was performed to investigate sociodemographic factors associated with early cochlear implantation (ie, before age 2 years). Geographic variability in pediatric cochlear implantation across hospital referral regions in California was described, and various parental factors associated with implantation before age 2 years were analyzed.

RESULTS

Among 182 children receiving cochlear implantations, the median (IQR) age was 3 (1-5) years and 58 children (31.9%) received implantations at ages 2 years or younger. There were 90 girls (49.5%) and 92 boys (50.5%), and among 170 children with race and ethnicity data, there were 27 Asian or Pacific Islander children (15.9%), 63 Hispanic children (37.1%), and 55 White children (32.4%). The risk of CI was significantly decreased among Black children compared with Asian or Pacific Islander children (relative risk [RR], 0.18 [95% CI, 0.07-0.47]; P = .001) and White children (RR, 0.24 [95% CI, 0.10-0.59]; P = .002) and among Hispanic children compared with Asian or Pacific Islander children (RR, 0.32 [95% CI, 0.21-0.50]; P < .001) and White children (RR, 0.42 [95% CI, 0.29-0.59; P < .001). Compared with private insurance, Medicaid insurance was associated with decreased odds of implantation at ages 2 years or younger (odds ratio [OR], 0.19 [95% CI, 0.06-0.64]; P = .007), and every 1 percentage point increase in maternal high school completion percentage in a given California hospital referral region was correlated with a 5-percentage point increase in percentage of cochlear implants performed at age 2 years or younger (b = 5.18 [95% CI, 1.34-9.02]; P = .008). There were no significant differences in rates of early implantation by race or ethnicity.

CONCLUSIONS AND RELEVANCE

This study found significant variability in pediatric cochlear implantation rates in California. These findings suggest that socioeconomic and parental factors may be associated with differences in access to early cochlear implantation and suggest the need to invest in initiatives to address barriers to appropriate and timely access to care.

Benefits of Parent Training in the Rehabilitation of Deaf or Hard of Hearing Children of Hearing Parents: A Systematic Review

The present study is a systematic review on the effectiveness of Parent Training (PT) and coaching in deaf and hard of hearing (DHH) rehabilitation programs which reviews and synthesizes the existing body of evidence to assess the benefits of these programs in enhancing parents' sensitivity, responsivity and promoting language development in DHH children during the first years after HA fitting or CI activation. Five published studies met the Population, Intervention, Comparison and Outcomes (PICO) inclusion criteria and were eligible to be included, but heterogeneity in terms of the study design, interventions and outcomes did not allow for performing a meta-analysis. All included studies shared the view that a parent's learning is a circular (rather than frontal) process, and the results appear promising in terms of enhancing parents' responsiveness and promoting DHH child language development. Nevertheless, the available evidence was judged to not be robust enough due to limitations in the studies' designs. Further high-quality evidence is needed to evaluate the true degree of clinical value and the cost effectiveness of PT programs aimed at increasing parents' responsiveness to their DHH children.

Parenting Stress, Self-Efficacy, and Involvement: Effects on Spoken Language Ability Three Years After Cochlear Implantation

OBJECTIVE

This study evaluated associations among parenting stress, self-efficacy, and involvement in relation to spoken language outcomes in young children 3 years following cochlear implantation.

STUDY DESIGN

Cross-sectional.

SETTING

Six university tertiary medical centers.

PATIENTS

One hundred sixty-four young children with bilateral, severe-to-profound sensorineural hearing loss who had 3 years of experience with a CI; children with substantial cognitive impairments were excluded from the study.

MAIN OUTCOME MEASURESS

Family Stress Scale (FSS), Scale of Parental Involvement and Self-Efficacy (SPISE), Oral and Written Language Scales (OWLS).

RESULTS

Correlations were of moderate strength between FSS scores and SPISE scores (Parental Self-Efficacy, r = -0.45, p < 0.01, Parental Involvement r = -0.32, p < 0.01). As hypothesized, parents reporting higher levels of stress reported lower perceptions of self-efficacy and involvement. In addition, results showed that family stress had a direct, negative effect on spoken language (-4.43 [95% confidence interval: -6.97; -1.89]). After controlling for maternal education and activation age, parental self-efficacy mediated the negative effect between family stress and spoken language (indirect effect = -1.91 [3.45; -0.69]; proportion mediated = 0.43). No mediating effects were found for parental involvement.

CONCLUSIONS

These findings highlight the need for parenting interventions that focus on reducing stressors and increasing parents' perceptions of self-efficacy in families of children using cochlear implants. Integration of mental health screening and tailored parenting interventions in CI clinics may increase parental self-efficacy and involvement, with measurable benefits in the child's use of spoken language.

Coaching Caregivers of Children who are Deaf or Hard of Hearing: A Scoping Review

Caregiver coaching is an expected practice in early intervention. However, little is known about coaching with caregivers of children who are deaf or hard of hearing, receiving services for listening and spoken language (LSL). A systematic review of 7 databases, the gray literature, and consultation with 7 expert LSL practitioners yielded 506 records for full-text review, 22 of which were ultimately included in the review. Our findings are presented as 3 themes: coaching practices, training for coaching, and effectiveness of coaching. Eight models of coaching were identified in the literature, from which we identified commonalities to propose a consolidated model that illustrates the recommendations and process of caregiver coaching found in the LSL literature.

Differential At-Risk Pediatric Outcomes of Parental Sensitivity Based on Hearing Status

Purpose The aim of this study was to investigate the role of parental sensitivity in language and neurocognitive outcomes in children who are deaf and/or hard of hearing (DHH). Method Sixty-two parent-child dyads of children with normal hearing (NH) and 64 of children who are DHH (3-8 years) completed parent and child measures of inhibitory control/executive functioning and child measures of sentence comprehension and vocabulary. The dyads also participated in a video-recorded, free-play interaction that was coded for parental sensitivity. Results There was no evidence of associations between parental sensitivity and inhibitory control or receptive language in children with NH. In contrast, parental sensitivity was related to children's inhibitory control and all language measures in children who are DHH. Moreover, inhibitory control significantly mediated the association between parental sensitivity and child language on the Clinical Evaluation of Language Fundamentals-Fifth Edition Following Directions subscale (6-8 years)/Clinical Evaluation of Language Fundamentals Preschool-Second Edition Concepts and Following Directions subscale (3-5 years). Follow-up analyses comparing subgroups of children who used hearing aids (n = 29) or cochlear implants (CIs; n = 35) revealed similar correlational trends, with the exception that parental sensitivity showed little relation to inhibitory control in the group of CI users. Conclusions Parental sensitivity is associated with at-risk language outcomes and disturbances in inhibitory control in young children who are DHH. Compared to children with NH, children who are DHH may be more sensitive to parental behaviors and their effects on emerging inhibitory control and spoken language. Specifically, inhibitory control, when scaffolded by positive parental behaviors, may be critically important for robust language development in children who are DHH.

Do Acoustic Environment Characteristics Affect the Lexical Development of Children With Cochlear Implants? A Longitudinal Study Before and After Cochlear Implant Activation

Purpose This study investigates the acoustic environment of children with cochlear implants (CIs) and the relationship between exposure to speech, in noise and in quiet, and the children's lexical production up to 1 year after CI activation, while controlling for the effect of early individual differences in receptive vocabulary growth. Method Eighteen children with CIs were observed at 3, 6, and 12 months after CI activation. Children's spontaneous word production during interaction with their mothers (types and tokens) and their expressive and receptive vocabulary size were considered. The characteristics of the acoustic environments in terms of acoustic scenes (speech in noise or in quiet, quiet, noise, music, and other) and of loudness ranges were assessed using data logging of the children's devices. Results Data analysis showed that both the number of tokens and the number of types produced 1 year after CI activation were affected by the children's exposure to speech in quiet with a loudness range between 40 and 69 dB. Expressive vocabulary size and types were affected by the receptive vocabulary knowledge that the children achieved over the first 3 months after CI activation. Conclusions Our data support the role of speech environment and individual differences in early comprehension on lexical production. The importance of exposure to speech with particular characteristics for the lexical development of children with CIs and the implications for clinical practice are discussed.

Assessing Parent Behaviours in Parent-Child Interactions with Deaf and Hard of Hearing Infants Aged 0-3 Years: A Systematic Review

Background: Despite early identification and advancements in cochlear implant and hearing aid technology, delays in language skills in deaf children continue to exist. Good-quality parent–child interaction (PCI) is a key predictor for the successful development of deaf children’s signed and/or spoken language. Though professionals have standard assessments to monitor child language, a clinical tool to observe the quality of parental interaction is yet to be developed. Aims and methods: This systematic review with narrative synthesis aims to uncover which parent behaviours are assessed in PCI studies with deaf infants aged 0–3 years, how these behaviours are assessed, and which are correlated with higher scores in child language. Results: Sixty-one papers were included, spanning 40 years of research. Research included in the review assessed parents’ skills in gaining attention, joint engagement, emotional sensitivity, and language input. PCI was mostly assessed using coding systems and frame-by-frame video analysis. Some of the parent behaviours mentioned previously are associated with more words produced by deaf children. Conclusion: The results of the review provide the evidence base required to develop the content of a future clinical assessment tool for parent–child interaction in deafness.

The Impact of Family Environment on Language Development of Children With Cochlear Implants: A Systematic Review and Meta-Analysis

OBJECTIVES

The authors conducted a systematic review of the literature and meta-analyses to assess the influence of family environment on language development in children with cochlear implants.

DESIGN

The Pubmed, excerpta medica dataBASE (EMBASE), Education Research Information Center, cumulative index to nursing and allied health literature (CINAHL), Healthcare Literature Information Network, PubPsych, and Social SciSearch databases were searched. The search strategy included terms describing family environment, child characteristics, and language development. Studies were included that (a) assessed distal family variables (such as parental income level, parental education, family size, and parental stress) with child language outcomes, and/or more proximal correlates that directly affect the child (such as family engagement and participation in intervention, parenting style, and more specifically, the quantity and quality of parental linguistic input) on child language; (b) included children implanted before the age of 5 years; (c) measured child language before the age of 21 years with standardized instruments; (d) were published between 1995 and February 2018; and (e) were published as peer-reviewed articles. The methodological quality was assessed with an adaptation of a previously validated checklist. Meta-analyses were conducted assuming a random-effects model.

RESULTS

A total of 22 study populations reported in 27 publications were included. Methodological quality was highly variable. Ten studies had a longitudinal design. Three meta-analyses on the correlations between family variables and child language development could be performed. A strong effect of the quality and quantity of parental linguistic input in the first 4½ years postimplantation on the child's language was found, r = 0.564, p ≤ 0.001, 95% confidence interval (CI) = 0.449 to 0.660, accounting for 31.7% of the variance in child language outcomes. Results demonstrated high homogeneity, Q(3) = 1.823, p = 0.61, I = 0. Higher-level facilitative language techniques, such as parental expansions of the child's utterances or the use of open-ended questions, predicted child language skills. Risk of publication bias was not detected. The results on the impact of family involvement/participation in intervention on child language development were more heterogeneous. The meta-analysis included mainly cross-sectional studies and identified low to moderate benefits, r = 0.380, p ≤ 0.052, 95% CI = -0.004 to 0.667, that almost attained significance level. Socioeconomic status, mainly operationalized by parental level of education, showed a positive correlation with child language development in most studies. The meta-analysis confirmed an overall low and nonsignificant average correlation coefficient, r = 0.117, p = 0.262, 95% CI = -0.087 to 0.312. A limitation of the study was the lack of some potentially relevant variables, such as multilingualism or family screen time.

CONCLUSIONS

These data support the hypothesis that parental linguistic input during the first years after cochlear implantation strongly predicts later child language outcomes. Effects of parental involvement in intervention and parental education are comparatively weaker and more heterogeneous. These findings underscore the need for early-intervention programs for children with cochlear implants focusing on providing support to parents for them to increase their children's exposure to high-quality conversation.

Prelinguistic Vocal Development in Children With Cochlear Implants: A Systematic Review

OBJECTIVES

This systematic review is designed to (a) describe measures used to quantify vocal development in pediatric cochlear implant (CI) users, (b) synthesize the evidence on prelinguistic vocal development in young children before and after cochlear implantation, and (c) analyze the application of the current evidence for evaluating change in vocal development before and after cochlear implantation for young children. Investigations of prelinguistic vocal development after cochlear implantation are only beginning to uncover the expected course of prelinguistic vocal development in children with CIs and what factors influence that course, which varies substantially across pediatric CI users. A deeper understanding of prelinguistic vocal development will improve professionals' abilities to determine whether a child with a CI is exhibiting sufficient progress soon after implantation and to adjust intervention as needed.

DESIGN

We systematically searched PubMed, ProQuest, and CINAHL databases for primary reports of children who received a CI before 5 years 0 months of age that included at least one measure of nonword, nonvegetative vocalizations. We also completed supplementary searches.

RESULTS

Of the 1916 identified records, 59 met inclusion criteria. The included records included 1125 total participants, which came from 36 unique samples. Records included a median of 8 participants and rarely included children with disabilities other than hearing loss. Nearly all of the records met criteria for level 3 for quality of evidence on a scale of 1 (highest) to 4 (lowest). Records utilized a wide variety of vocalization measures but often incorporated features related to canonical babbling. The limited evidence from pediatric CI candidates before implantation suggests that they are likely to exhibit deficits in canonical syllables, a critical vocal development skill, and phonetic inventory size. Following cochlear implantation, multiple studies report similar patterns of growth, but faster rates producing canonical syllables in children with CIs than peers with comparable durations of robust hearing. However, caution is warranted because these demonstrated vocal development skills still occur at older chronological ages for children with CIs than chronological age peers with typical hearing.

CONCLUSIONS

Despite including a relatively large number of records, the evidence in this review regarding changes in vocal development before and after cochlear implantation in young children remains limited. A deeper understanding of when prelinguistic skills are expected to develop, factors that explain deviation from that course, and the long-term impacts of variations in vocal prelinguistic development is needed. The diverse and dynamic nature of the relatively small population of pediatric CI users as well as relatively new vocal development measures present challenges for documenting and predicting vocal development in pediatric CI users before and after cochlear implantation. Synthesizing results across multiple institutions and completing rigorous studies with theoretically motivated, falsifiable research questions will address a number of challenges for understanding prelinguistic vocal development in children with CIs and its relations with other current and future skills. Clinical implications include the need to measure prelinguistic vocalizations regularly and systematically to inform intervention planning.

Family Environment in Children With Hearing Aids and Cochlear Implants: Associations With Spoken Language, Psychosocial Functioning, and Cognitive Development

OBJECTIVES

To examine differences in family environment and associations between family environment and key speech, language, and cognitive outcomes in samples of children with normal hearing and deaf and hard-of-hearing (DHH) children who use hearing aids and cochlear implants.

DESIGN

Thirty families of children with normal hearing (n = 10), hearing aids (n = 10), or cochlear implants (n = 10) completed questionnaires evaluating executive function, social skills, and problem behaviors. Children's language and receptive vocabulary were evaluated using standardized measures in the children's homes. In addition, families were administered a standardized in-home questionnaire and observational assessment regarding the home environment.

RESULTS

Family environment overall was similar across hearing level and sensory aid, although some differences were found on parental responsivity and physical environment. The level of supportiveness and enrichment within family relationships accounted for much of the relations between family environment and the psychosocial and neurocognitive development of DHH children. In contrast, the availability of objects and experiences to stimulate learning in the home was related to the development of spoken language.

CONCLUSIONS

Whereas broad characteristics of the family environments of DHH children may not differ from those of hearing children, variability in family functioning is related to DHH children's at-risk speech, language, and cognitive outcomes. Results support the importance of further research to clarify and explain these relations, which might suggest novel methods and targets of family-based interventions to improve developmental outcomes.

Assessing parent-child interaction in infant deafness

PURPOSE OF REVIEW

To highlight the importance of parent-child interaction (PCI) in infant deafness and address the lack of robust assessment tools in clinical practice.

RECENT FINDINGS

Most deaf babies are born to hearing parents with little experience in deafness. Deafness can reduce access to spoken language. Despite advancements in amplification technology, deaf children still present with delays in attention and communication skills at the start of nursery. Research reports that hearing parents of deaf infants can be more directive during interaction, spend less time following the child's focus of attention, and have more difficulty achieving successful turn-taking in conversation. Much research tells us that these factors impact on the quality and quantity of PCI. Good PCI, in all infants, but especially so in deafness, is a strong predictor of child language outcomes. Teachers of the Deaf and Speech and Language Therapists are the first professionals to support families in the home. For these professionals, having an objective way of assessing PCI would greatly assist and standardise their practice. However, to date, there are no deaf-specific assessments to observe and appraise a parent's communication behaviours when interacting with their deaf child.

SUMMARY

Intervention studies with families of deaf children have shown success in improving parental sensitivity and facilitative language techniques. An observational assessment in parent-deaf child interaction would ensure that communication interventions are appropriately targeted on the individual family's needs.

Positive Parenting Behaviors: Impact on the Early Vocabulary of Infants/Toddlers With Cochlear Implants

Purpose To extend our knowledge about factors influencing early vocabulary development for infants with cochlear implants (CIs), we investigated the impact of positive parenting behaviors (PPBs) from the Indicator of Parent Child Interaction, used in parent-child interactions during everyday activities. Method Implantation age for the sample recruited from CI clinics in Australia ranged from 6 to 10 months for 22 children and from 11 to 21 months for 11 children. Three observation sessions at three monthly intervals were coded for use of PPBs. Children's productive vocabulary, based on the MacArthur-Bates Communicative Development Inventories parent checklist, was collected approximately 6 and 9 months later. A repeated-measures negative binomial generalized linear mixed-effects model was used to investigate associations between the total PPBs per session, covariates (maternal education, gender, and time since implant), and the number of words produced. In follow-up analyses with the PPBs entered separately, variable selection was used to retain only those deemed informative, based on the Akaike information criterion. Results As early as Session 1, associations between the PPBs and vocabulary were identified. Time since implant had a positive effect. For different sessions, specific PPBs (descriptive language, follows child's lead, and acceptance and warmth) were identified as important contributors. Conclusions Complementing previous findings, valuable information was identified about parenting behaviors that are likely to impact positively the early vocabulary of infants with CIs. Of importance is providing parents with information and training in skills that have the potential to help create optimal contexts for promoting their child's early vocabulary development.

Effects of Parents' Mealtime Conversation Techniques for Preschool Children With Hearing Loss Who Use Listening and Spoken Language

Purpose This mixed-methods study aimed to examine the conversation techniques used by parents of young children with hearing loss (HL) during dinnertime at home. Parents' usage rates of open- and closed-ended language elicitation, reformulation, imitation, directives, and explicit vocabulary instruction were examined in relation to children's receptive vocabulary and basic-concepts skills. Method Twenty-minute dinnertime segments were extracted from naturalistic, daylong recordings of 37 preschoolers with HL who used listening and spoken language. The segments were hand-coded for parents' use of conversation techniques. Children's receptive vocabulary and basic concepts were assessed using standardized measures. Results Parents' use of conversation techniques varied widely, with closed-ended elicitation and directives used most frequently during dinner. Explicit vocabulary instruction was correlated with general receptive vocabulary and basic-concepts skills. Thematic analysis of the conversations revealed common themes, including concrete topics and sibling speakers. In addition, parents who used many techniques often introduced abstract conversation topics; electronic media was present in all conversations with few techniques. Conclusions Parents of preschoolers with HL may benefit from specific coaching to elicit language and introduce new vocabulary during home routines. These techniques may help develop their children's receptive language.

Impaired Face-to-Face Interaction among Cochlear Implant Users: Toward a Micro-sociological Framework

The technological advance of cochlear implants (CIs) has provided deaf and hearing-impaired persons with new opportunities to acquire hearing and thus partake in social life on more equal terms. However, recent studies have also documented communicative and emotional difficulties for some CI users, in particular concerning how crowded and noisy situations may lead to high mental energy use and communicative constraints on social participation. Despite this accumulating evidence, few attempts have been made to provide sociological explanations of such aversive outcomes. Here, the authors develop and outline a micro-sociological framework suggesting impaired verbal interactions as a source of emotional energy drain and subsequent dis-integrations and estrangement in the social bond. The authors demonstrate the relevance of this theoretical explanation through a qualitative analysis of eight interviews with adults who had CIs placed as children. The authors discuss the implications of this framework and findings for CI research and users.

Developmental outcomes of young deaf children and the self-perceived parental role of their hearing mothers

BACKGROUND

There is little research into the relationship between a deaf child's developmental outcomes and their mother's self-perceived parental role. The aim of this study was to find out whether the different levels of global psychomotor development in young deaf children who had a cochlear implant (CI), or were candidates for a CI, were related to particular family factors: the self-perceived parental role and the family quality of life (FQoL) as gauged by their hearing mothers, as well as the child's sociodemographic and deafness-related factors and the sociodemographic characteristics of the mothers.

METHODS

The study was conducted on a group of 64 children with bilateral severe or profound sensorineural hearing loss (SNHL) who were CI users (36 children) or qualified for cochlear implantation (28 children) and their hearing mothers. The age of the children ranged from 6.5 to 47 months (M = 23.6; SD = 10.1), among whom 55% were girls (n = 35). The mothers of the children were aged 24-48 years (M = 32.7; SD = 5.3). Information was collected via the Children Development Scale (CDS), the Self-Perception of Parental Role (S-PPR), the Family Quality of Life Survey (FQOLS-2006), and an additional information questionnaire which included questions about sociodemographic variables of the child and the mother, as well as questions related to deafness, the CI, and the child's rehabilitation.

RESULTS

Based on results of the CDS, the deaf children were divided into two groups: those who had a low level of global psychomotor development (Low global psychomotor development subgroup - LGPD) and others with medium or high scores (Medium/high global psychomotor development subgroup - MHGPD). The mothers of deaf children in the LGPD group assessed their investment in motherhood lower than did mothers from the MHGPD group. The mothers of the LGPD group rated their satisfaction with the child's rehabilitation lower than did mothers from the MHGPD group. The two subgroups did not differ in FQOLS-2006 domains except for community interactions, which were significantly higher in the MHGPD families.

CONCLUSIONS

Among the determinants of the global psychomotor development of a young deaf child, the most important ones relate to the use of a CI, but maternal investment in parenting is also important. Community interactions of the family with a deaf child are also crucial, as they create a framework for social network and support for the deaf child's optimal development. Any psychological diagnosis should include, apart from psychomotor development of the deaf child, an assessment of how the mother is coping with their parenting. Mothers of deaf children, especially those with LPGD, need additional support in parenting.

Developing new scales for assessing parents' aural and oral rehabilitation skills to interact with children with hearing loss

OBJECTIVE

Scales for evaluating the teaching and behavioural skills of parents enrolled in aural and oral rehabilitation programs for children with hearing loss are lacking. This study developed and validated scales for assessing parental teaching and behavioural skills of those parents for use in guiding their child to develop language and communication skills.

DESIGN

Scales were constructed and evaluated using exploratory and confirmatory factor analysis. The performance of parents in teaching and behavioural skills was also explored.

STUDY SAMPLE

The teaching and behavioural skills of 344 parents (179 for scale development and 165 for validation) were rated by their intervention therapists using parental teaching skill (PTS) and parental behavioural skill (PBS) scales.

RESULTS

Good reliability and model fit (validity) were observed for both scales, which ultimately included 13 and 10 items, respectively. Maternal educational level was a significant indicator of their performance ratings.

CONCLUSIONS

The PTS and PBS scales were validated and can be used by early intervention professionals to evaluate the relative interaction and behavioural skills of parents of children with hearing loss, and enrolled in listening and spoken language intervention programs.

Frühe Prädiktoren der Sprachentwicklung von Kindern mit permanenter Hörstörung

Zusammenfassung. Theoretischer Hintergrund: Sprachentwicklungsverläufe bei Kindern mit Hörstörungen zeigen eine hohe und überwiegend ungeklärte Varianz. Fragestellung und Methode: Unsere Übersichtsarbeit präsentiert aktuelle Evidenz zu frühen Prädiktoren der Sprachentwicklung. Ergebnisse und Diskussion: Trotz deutlicher positiver Trends erreicht nur jedes zweite Kind ein Sprachentwicklungsniveau im Normbereich. Der Literaturüberblick ergibt signifikante kindbezogene und familiäre Prädiktoren mit eher geringer Beeinflussbarkeit. Als hoch prädiktiv für sprachliche Ergebnisse und zudem der Intervention zugänglich erweisen sich die frühe Erkennung und technische Versorgung mit Hörgeräten oder -implantaten und Aufnahme in die Frühförderung, konsistente Hörtechnikverwendung und/oder früher Zugang zur Gebärdensprache. Zudem zeigt sich die Qualität der täglichen Eltern-Kind-Interaktion als hocheffektiv für die Sprachentwicklung. Schlussfolgerung: Es bestätigt sich die Wirksamkeit aktueller Best Practice früher Erkennung, Versorgung und familienzentrierter Frühförderung.

Relational Factors in Pragmatic Skill Development: Deaf and Hard of Hearing Infants and Toddlers

In this article, we review relational factors in early childhood believed to contribute in unique ways to pragmatic skill development in deaf and hard of hearing (DHH) infants and toddlers. These factors include attending to infant interactions with caregivers and others, supporting development of theory of mind through play and use of mental state language (ie, describing one's own or others' thoughts, feelings, and beliefs), and providing accessible opportunities for social interaction. On the basis of a review of the literature and clinical experience, we offer prescriptive strategies for supporting DHH children's development in these areas. To improve outcomes for DHH children, medical care providers and allied health professionals have a responsibility to support the development of young DHH children's pragmatic abilities by understanding these variables, coaching caregivers regarding their importance, and facilitating referrals for support when necessary.

Cochlear implant datalogging accurately characterizes children's 'auditory scenes'

Objectives: This study sought to determine if children's auditory environments are accurately captured by the automatic scene classification embedded in cochlear implant (CI) processors and to quantify the amount of electronic device use in these environments. Methods: Seven children with CIs, 36.71 (SD = 11.94) months old, participated in this study. Three of the children were male and four were female. Eleven datalogs, containing outcomes from Cochlear's™ Nucleus^® 6 (Cochlear Corporation, Australia) CI scene classification algorithm, and seven day-long audio recordings collected with a Language ENvironment Analysis (LENA; LENA Research Foundation, USA) recorder were obtained for analysis. Results: Results from the scene classification algorithm were strongly correlated with categories determined through human coding (ICC = .86, CI = [-0.2, 1], F(5,5.1) = 5.9, P = 0.04) but some differences emerged. Scene classification identified more 'Quiet' (t(8.2) = 4.1, P = 0.003) than human coders, while humans identified more 'Speech' (t(10.6) = -2.4, P = 0.04). On average, 8% (SD = 5.8) of the children's day was spent in electronic sound, which was primarily produced by mobile devices (39.7%). Discussion: While CI scene classification software reflects children's natural auditory environments, it is important to consider how different scenes are defined when interpreting results. An electronic sounds category should be considered given how often children are exposed to such sounds.

Advances in Inner Ear Therapeutics for Hearing Loss in Children

Purpose of review

Hearing loss is a common congenital sensory disorder with various underlying causes. Here, we review and focus on genetic, infectious, and ototoxic causes and recent advances in inner ear therapeutics.

Recent findings

While hearing aids and cochlear implantation are the mainstay of treatment for pediatric hearing loss, novel biological therapeutics are being explored. Recent preclinical studies report positive results in viral-mediated gene transfer techniques and surgical approaches to the inner ear for genetic hearing loss. Novel pharmacologic agents, on the other hand, show promising results in reducing aminoglycoside and cisplatin ototoxicity. Clinical trials are underway to evaluate the efficacy of antivirals for cytomegalovirus-related hearing loss, and its pathogenesis and other potential therapeutics are currently under investigation.

Summary

Individualized therapies for genetic and infectious causes of sensorineural hearing loss in animal models as well as pediatric patients show promising results, with their potential efficacy being active areas of research.

Communication Skills and Communicative Autonomy of Prelinguistic Deaf and Hard-of-Hearing Children: Application of a Video Feedback Intervention

Background and Aim

Evidence on the efficacy of parenting interventions to support communication development in deaf and hard-of-hearing children is emerging. In previous research, we showed that parental participation in a video feedback-based intervention enhanced parental self-esteem and emotional availability to their deaf and hard-of-hearing children. This paper investigates the impact of the intervention on the development of the children's prelingual communication skills and autonomy. Evidence on the efficacy of parenting interventions to support communication development is warranted.

Methods

Sixteen hearing parents with a prelingual deaf and hard-of-hearing child (Mage = 2.05 years, SD = 1.77) were recruited by self-selection from pediatric audiological services and randomly stratified into intervention-first and waiting-list groups. Families completed three sessions of Video Interaction Guidance in their homes. Designed for maximal inclusion, the sample comprised children with complex developmental and social needs. The primary inclusion criterion was the child's prelingual status (<50 signed/spoken words), which was established using speech and language therapy reports. Child communicative autonomy was assessed from a 20 min free-play video recording using a gold standard measure for deaf and hard-of-hearing children (Tait) before and after the intervention.

Results

A Mann-Whitney U test indicated no significant difference between the two groups. The groups were collated, and a Wilcoxon signed-rank test with time (pre-/post-intervention) as a repeating variable was run. A significant increase in children's communicative autonomy (Z = -3.517, p < 0.0001, d = 0.62) and decrease in children's no-responses (Z = -3.111, p < 0.005, d = 0.55) were seen. There was no significant difference in the overall number of turn-taking between the parent and child, indicating differences in the quality of the parent-child interactions, not the quantity.

Conclusion

This study adds to the emerging evidence for parenting interventions with deaf and hard-of-hearing children. We hypothesize that the video feedback intervention with its focus on emotional availability created space for the children to show increased communicative autonomy during parent-child interactions. Communicative autonomy is a long-term predictor of communication and linguistic development in deaf and hard-of-hearing children, and its conceptual underpinning makes it a good early measure of relational agency. Results can inform wider interventions that focus on the quantity of the parent-child communication.
