Behavior problems in children with cochlear implants

Psychological Health of Deaf Pre-Teens and Teenagers with Cochlear Implants and Maternal Psychological Features: A Pilot Study

BACKGROUND/OBJECTIVES

The psychological health of deaf children and adolescents with cochlear implants (CIs) appears to be related to the degree of auditory and linguistic recovery achieved, as well as contextual factors. Few studies have investigated the influence that maternal psychological characteristics and resources may have in supporting the mental health of these children and adolescents. The aim of this pilot study was to investigate the psychological well-being of pre-teens/teenagers with CIs and the mental health of their mothers. The secondary aim was to analyze which maternal characteristics (anxiety, depression, resilience, and time spent sharing emotions) were most related to the psychological health of the pre-teen/teenager.

METHODS

A group of 15 pre-teens/teenagers with CIs and 27 hearing peers and their mothers participated in the study. The Strengths and Difficulties Questionnaire, the Generalized Anxiety Disorder Scale, the Beck Depression Inventory II, the Connor-Davidson Resilience Scale, and an additional ad hoc question quantifying the time that the mothers dedicate to conversing with their sons/daughters about the emotions were administered to the included subjects.

RESULTS

No significant differences between the two groups of pre-teens/teenagers emerged; however, a great percentage of pre-teens/teenagers with CIs appeared at higher risk for developing psychopathology. The resilience scores for both groups of mothers were lower than anticipated and related to the psychological health of pre-teens/teenagers.

CONCLUSIONS

These results underscore the need for targeted psychological support alongside auditory rehabilitation and suggest avenues for enhancing family-centered care in this clinical population.

Empathy Development in Preschoolers With/Without Hearing Loss and Its Associations with Social-Emotional Functioning

Empathy plays a crucial role in children's social-emotional development. There is an increasing trend in recent studies to recognize empathy as a multi-dimensional construct, consisting of three distinct hierarchical levels: emotion contagion, attention to others' feelings and prosocial behaviors (Hoffman, Motiv Emot, 14(2), 151-172, 1990). The present study is amongst the first to use a longitudinal approach to examine the development trajectories of the distinct empathic levels, based on a sample of Chinese preschoolers aged 2 to 6 years, half of the sample being deaf or hard-of-hearing (DHH). Our results showed that according to the parental observation, DHH preschoolers manifested similar extent of emotion contagion and attention to others' feelings as their TH (typically hearing) peers over preschool years. Yet, DHH preschoolers showed fewer prosocial behaviors, compared to their TH peers. As for the longitudinal associations over time, emotion contagion contributed to more internalizing and externalizing behaviors in both groups; whilst attention to others' feelings contributed to fewer internalizing behaviors in only DHH children. Prosocial behaviors contributed to better social competence, and fewer internalizing and externalizing behaviors in both DHH and TH children just as expected. These outcomes imply that the early intervention or special education may be useful to safeguard children's empathic development, shrinking the gaps between DHH and TH children; but meanwhile, cultural factors might cause latent effects on children's understandings of empathy and impact on how empathy "regulates" children's social-emotional functioning, in a Chinese cultural context.

The impact of noise-induced hearing loss on individual job performance: exploring the role of aggression and work-related quality of life

BACKGROUND

Noise-Induced Hearing Loss (NIHL) may have a significant effect on individual job performance (IJP). These effects may exert through aggression and work-related quality of life (WRQoL). Hence, the present study was conducted to investigate the modeling of the impact of NIHL on IJP by exploring the role of aggression and WRQoL.

METHODS

In 2022, a comprehensive study was carried out on 335 industrial workers in Kaveh Industrial Town, Saveh, Iran. The study encompassed a range of assessments, including a questionnaire-based survey that included the IJP questionnaire, WRQoL questionnaire, and Aggression questionnaire, as well as a pure tone audiometry test. The data gathered from these assessments were analyzed using structural equation modeling, providing a robust framework for understanding the complex relationships between variables.

RESULTS

Based on Spearman correlation test there is a negative correlation between NIHLtotal and WRQoL and IJP, with coefficients of -0.459 (P-value < 0.01) and - 0.575 (P-value < 0.01), respectively. Additionally, there is a positive correlation between NIHLtotal and aggression, with a coefficient of 0.374 (P-value < 0.05). The direct effect coefficients for the impact of NIHLtotal on WRQoL, aggression, and IJP were - 0.412, 0.453, and - 0.128, respectively. Moreover, the indirect effect coefficients of NIHLtotal on the IJP through aggression, through WRQoL, and through both aggression and WRQoL were - 0.057, -0.275, and - 0.078, respectively.

CONCLUSION

Overall, the results indicate that NIHL had a negative and positive association with WRQoL and aggression among workers, respectively. Furthermore, IJP was found to be directly and indirectly influenced by NIHL, through reduced WRQoL and aggressive behavior as negative consequences of NIHL.

A longitudinal study on moral emotions and psychosocial functioning among preschool children with and without hearing loss

Moral emotions such as shame, guilt and pride are crucial to young children's social-emotional development. Due to the restrictions caused by hearing loss in accessing the social world, deaf and hard of hearing (DHH) children may encounter extra difficulties in their development of moral emotions. However, little research so far has investigated the development trajectory of moral emotions during preschool years in DHH children. The present study used a longitudinal design to explore the development trajectories of shame, guilt, and pride, in a sample of 259 Chinese DHH and typically hearing (TH) preschoolers aged 2 to 6 years old. The results indicated that according to parent reports, DHH children manifested lower levels of guilt and pride compared to their TH peers, yet the manifested levels of shame, guilt, and pride increased throughout the preschool time at a similar pace in all children. Moreover, whilst guilt and pride contributed to increasing levels of psychosocial functioning over the preschool years, shame contributed to lower social competence and more externalizing behaviors in DHH and TH preschoolers. The outcomes imply that early interventions and adjustment to hearing loss could be useful to safeguard the social development of children with severe hearing loss, and cultural variances shall be taken into consideration when studying moral emotions in a Chinese cultural background.

A systematic review on the impact of auditory functioning and language proficiency on psychosocial difficulties in children and adolescents with hearing loss

OBJECTIVE

Approximately 20% to 40% of children with hearing loss encounter psychosocial difficulties. This prevalence may be outdated, given the advancements in hearing technology and rehabilitation efforts to enhance the psychosocial well-being of these children. A systematic review of up-to-date literature can help to identify factors that may contribute to the children's psychosocial well-being.

DESIGN/STUDY SAMPLE

A systematic review was conducted. Original articles were identified through systematic searches in Embase, Medline, PsychINFO, and Web of Science Core Collection. The quality of the papers was assessed using the Newcastle-Ottawa Quality Assessment Scale and custom Reviewers' Criteria.

RESULTS

A search was performed on 20 October 2022. A total of 1561 articles were identified, and 36 were included for review. Critical appraisal led to 24 good to fair quality articles, and 12 poor quality articles.

CONCLUSION

Children with hearing loss have a twofold risk of experiencing psychosocial difficulties compared to normal hearing peers. Estimates for functioning in social interactions, like speech perception (in noise) or language proficiency, have proven to be more adequate predictors for psychosocial difficulties than the degree of hearing loss. Our findings can be useful for identifying children at risk for difficulties and offering them earlier and more elaborate psychological interventions.

Evaluating the Relation Between Mothers' Depression Level and Their Cochlear Implanted Children's Social Performance

Since the child's sensorineural hearing loss and its negative consequences, including weak social skills, is one of the most challenging problems for parents and other family members, the main aim of the present study is to investigate if there is any probable relation between the cochlear implanted children's social performance and their mothers' depression level,in this cross-sectional observational analytic research, we implemented the Beck Depression Inventory version- II to evaluate the level of depression in 29 mothers of cochlear implanted children. Also, we assessed their children's social abilities through the Vineland Adaptive Behavior Scale. Finally, the analysis of variance (ANOVA) was carried out to find any probable relation between the mothers' depression level and their children's social performance. The mean difference was significant at the 0.05 level,results indicated no significant difference in the mean social performance of the children mothers encountered with mild or moderate degrees of depression. However, the mean social performance of the children with severely depressed mothers was significantly less than the others,severe to profound sensorineural hearing loss in children might cause various degrees of depression in mothers. Mothers who suffer from severe depression cannot effectively communicate with their children. Consequently, the child will not improve in social interaction well.

Innovative protocol of an exploratory study evaluating the acceptability of a humanoid robot at home of deaf children with cochlear implants

The purpose of this paper is to introduce a research methodology for the assessment of the acceptability of a humanoid robot at home for children with cochlear implants (CI). The quality of audiology rehabilitation for cochlear implanted child administrated at the hospital with pluri-weekly sessions is a major prognostic factor in the outcome on communications abilities, but represents also a constraint for families related to the access to care that are more difficult. Further, home training with tools would balance the equitable distribution of care in the territory and promote the child's progress. The humanoid robot should allow an ecological approach to this complementary training. Before developing this approach, it is necessary to study the acceptability of the humanoid robot at home, both by cochlear implanted child and their families. Ten families were chosen to have a humanoid robot at home, to explore their acceptability of the humanoid robot Pepper. The study lasts for 1 month per participants (i.e. cochlear implemented children and parent). Participants were invited to use the robot at home as much as they want. The humanoid robot Pepper was able to communicate and proposed activities not related to rehabilitation. Once a week during the study, data were collected from participants (questionnaires and robot's logs) and the smooth running of the study was checked. Questionnaires are used to evaluate the acceptability of the robot by children and parents. User data from the robot's logs are used to quantify the time and the actual use of the robot over the period of the study. Results of the experimentation will be reported, once all 10 participants have completed their passation. The robot is anticipated to be used and accepted by children with cochlear implants and their families. Clinical trial registration: Clinical Trials ID: NCT04832373; https://clinicaltrials.gov/.

Auditory evoked response to an oddball paradigm in children wearing cochlear implants

OBJECTIVE

Although children with cochlear implants (CI) achieve remarkable success with their device, considerable variability remains in individual outcomes. Here, we explored whether auditory evoked potentials recorded during an oddball paradigm could provide useful markers of auditory processing in this pediatric population.

METHODS

High-density electroencephalography (EEG) was recorded in 75 children listening to standard and odd noise stimuli: 25 had normal hearing (NH) and 50 wore a CI, divided between high language (HL) and low language (LL) abilities. Three metrics were extracted: the first negative and second positive components of the standard waveform (N1-P2 complex) close to the vertex, the mismatch negativity (MMN) around Fz and the late positive component (P3) around Pz of the difference waveform.

RESULTS

While children with CIs generally exhibited a well-formed N1-P2 complex, those with language delays typically lacked reliable MMN and P3 components. But many children with CIs with age-appropriate skills showed MMN and P3 responses similar to those of NH children. Moreover, larger and earlier P3 (but not MMN) was linked to better literacy skills.

CONCLUSIONS

Auditory evoked responses differentiated children with CIs based on their good or poor skills with language and literacy.

SIGNIFICANCE

This short paradigm could eventually serve as a clinical tool for tracking the developmental outcomes of implanted children.

Effectiveness of unified protocols for online transdiagnostic treatment on social-emotional skills and parent-child interaction in school-aged children with cochlear implants

OBJECTIVES

Children with cochlear implants have limitations in emotional and cognitive social maturity which impact on their future emotional, social, and cognitive development. The main aim of this study was to evaluate the effect of a unified protocol for online transdiagnostic treatment program on social-emotional skills (self-regulation, social competence, responsibility, sympathy) and parent-child interaction (conflict, dependence, closeness) in children with cochlear implant.

MATERIALS AND METHODS

The present study was a quasi-experimental design with a pre-test-post-test and follow-up. Mothers of 18 children with cochlear implant aged from 8 to 11 years were randomly divided into experimental and control groups. 10 weeks of semi-weekly sessions for a total of 20 sessions around 90 min for children and 30 min for their parents were selected. Social-emotional assets, resilience scale (SEARS) and children parent relationship scale (CPRS) were selected to evaluate social-emotional skills and parent-child interaction respectively. We used Cronbach alpha, Chi-square test, independent sample t-test, and univariate ANOVA for statistical analyses.

RESULTS

Behavioral tests had relatively high internal reliability. Means scores in self-regulation was statistically different in pre-test and post-test conditions (p-value = 0.005) and pre-test and follow-up conditions (p-value = 0.024). Total means scores were showed a significant difference in pretest and post-test (p-value = 0.007) not in follow-up (p > 0.05). The interventional program could improve the parent-child relationship only in conflict and dependence (p < 0.05), and it was constant with time (p < 0.05).

CONCLUSION

Our study demonstrated an effect of online transdiagnostic treatment program on social-emotional skills of children with cochlear implants, especially in self-regulation and total score which were stable after three months in self-regulation. Moreover, this program could impact on the parent-child interaction only in conflict and dependence which was stable with time.

Assessment of Behavioral Problems in Children Pre- and Post-Cochlear Implant: An Egyptian Study

OBJECTIVE

The present study aimed to detect the behavioral problems pre- and post-cochlear implantation in comparison to normal hearing group to be able to manage these problems to get more benefit from using cochlear implants.

METHODS

A case-control study included 53 children was done. They were divided into 2 groups, the control group included 28 healthy volunteers with normal hearing and the case group included 25 children with severe to profound hearing loss, fitted for cochlear implantation. The Arabic Child Behavior Checklist (CBCL) was used to detect different behavioral problems in both groups. Case group children were followed up and reassessed again by CBCL 3 months later after cochlear implantation.

RESULTS

There were highly significant differences regarding total scores of internalizing and externalizing domains of empirically based CBCL between the control group and the case group after cochlear implants (p=0.001). There were non-significant differences in children within case group (pre- and post-cochlear implantation) regarding emotional and behavioral problems on both empirically based and Diagnostic and Statistical Manual of Mental Disorders-based CBCL.

CONCLUSION

For better results, it is necessary to include a specialist of psychosomatic medicine in the cochlear rehabilitation teamwork.

Examination of Language, Behavioral, Academic, and Social Skills of Cochlear Implant Users in Early Primary Education

BACKGROUND

 Cochlear implants (CIs) improve spoken language skills as well as social and academic performance in children with severe and profound sensorineural hearing loss.

PURPOSE

 We compare the social skills, academic competence, and problem behaviors in children with CIs and their typical-hearing peers and investigate the relationship between language skills and social skills, academic competence, and problem behaviors in children with CIs.

RESEARCH DESIGN

 Thirty-two children with CIs were divided into two groups according to implantation age: early (n = 17) and late-implanted group (n = 15). The control group was formed by the inclusion of five same-sex classmates of each implanted child selected by the teachers of the children with CIs. Thus, 160 typical-hearing children were included in the control group.

STUDY SAMPLE

 Thirty-two children with CIs and 160 typical-hearing children participated in this study.

DATA COLLECTION AND ANALYSIS

 Primary school teachers rated the children's social skills, academic competence, and problem behaviors using the Social Skills Rating System (SSRS). The language skills of the children with CIs were assessed with the Turkish Expressive and Receptive Language Test (TIFALDI).

RESULTS

 A statistically significant difference was found between the SSRS scores of the study and control groups, which was mostly due to lower social skills, and academic competence, and higher problem behavior ratings in the late-implanted group. In the study group, there was a statistically significant correlation between TIFALDI and SSRS scores.

CONCLUSION

 Early cochlear implantation provides advantages in social skills and vocabulary for children with profound congenital hearing loss. Late-implanted children need special support in different developmental areas despite attending mainstream education.

Experience of adult cochlear implantation at a tertiary hospital

BACKGROUND

The prevalence of adult cochlear implant (CI) surgery is increasing. However, the relevant adult CI data in Taiwan are insufficient due to the relatively small number of adult implant patients. The two main factors hindering adult implantation are the high cost of the surgery itself and inadequate knowledge regarding the effectiveness of CI for hearing and suppression of tinnitus. Here, we present data regarding adult CI outcomes from a single tertiary hospital.

METHODS

A total of 116 consecutive adult CI recipients (≥18 years old) who completed at least 12 months of speech perception tests (words and sentences) between January 1999 and December 2020 were enrolled in this retrospective population-based cohort study. Thirty patients completed speech perception (words and sentences) testing as well as three questionnaires relating to quality of life, and 71 completed full tinnitus suppression studies. Subjects' pre- and post-CI questionnaires were evaluated to assess overall CI outcome.

RESULTS

For auditory evaluation, the scores of easy sentences (ES), difficult sentences (DS), and phonetically balanced (PB) word recognition tests reached a plateau at 3 months post-CI (p = 0.005, 0.001, and 0.004, respectively) in most subjects. The post-CI scores of bodily pain, mental health, and social role functioning were significantly higher than corresponding pre-CI scores on the SF-36 Health Survey-Taiwan version (p = 0.036, 0.019, and 0.002, respectively). Furthermore, the post-CI scores of basic sound perception, speech production, and advanced sound perception were significantly higher than the corresponding pre-CI scores on the Nijmegen Cochlear Implant Questionnaire (p < 0.001, 0.013, and <0.001, respectively). Self-esteem was significantly correlated with the Categories of Auditory Performance scale and Speech Intelligibility Rating scale at 3, 6, and 9 months post-CI. CI improved tinnitus in approximately 65.1% of 71 adults. Based on the Tinnitus Handicap Inventory, 66.7% of patients were in grade 3-5 before surgery. However, after CI, only 34.4% of patients remained in THI grade 3-5.

CONCLUSION

This study confirmed that CI can improve speech perception (words and sentences), physical health, mental health, social interaction, and self-esteem in adult patients with profound hearing loss. CI also significantly alleviated tinnitus. The outcomes of ES, DS, and PB tests at 3 months post-CI were non-inferior to other longer post-CI periods and could be utilized as references for recovery and evaluation of prognosis.

Effects of design and coupling parameters on the performance of electromagnetic transducers in round-window stimulation

Many studies have investigated factors contributing to large variations in the outcomes of round-window (RW) stimulation but most have focused on the floating mass transducer (FMT). To determine whether results for the FMT hold for a fixed-type transducer (FTT), this study constructs two coupled finite element models of the transducer and the human ear that incorporate the cochlear third windows and inner structures of these two electromagnetic transducers. We use these FE models of the human ear and transducers to investigate the influence of four design parameters and coupling conditions for the transducers, i.e., the support's Young's modulus, the coupling layer's cross sectional area and Young's modulus, and the transducer's cross sectional area. The results show that an increase in the support's Young's modulus reduces the output of the FMT but increases that of the FTT. Reducing the cross sectional area and Young's modulus of the coupling layer significantly increases the low-frequency response of the FMT but slightly reduces that of the FTT. Reducing the cross sectional area of the transducer increases the output of the FMT but reduces that of the FTT. This shows that inner structures of electromagnetic transducers should be considered in the optimal design parameters and coupling conditions for RW stimulation.

Emotions in Deaf and Hard-of-Hearing and Typically Hearing Children

For deaf and hard-of-hearing (DHH) children living in an environment where their access to linguistic input and social interactions is compromised, learning emotions could be difficult, which may further affect social functioning. To understand the role of emotion in DHH children's social life, this study investigated emotional functioning (i.e., emotion recognition, empathy, emotion expression), and its relation with social functioning (i.e., social competence and externalizing behaviors), in 55 DHH children and 74 children with typical hearing (aged 3-10 years; Mage = 6.04). Parental reports on children's emotional and social functioning and factors related to DHH children's hearing were collected. Results showed similar levels of emotional and social functioning in children with and without hearing loss. Use of auditory intervention and speech perception did not correlate with any measures in DHH children. In both groups, higher levels of empathy related to higher social competence and fewer externalizing behaviors; emotion recognition and positive emotion expression were unrelated to either aspect of social functioning. Higher levels of negative emotion expression related to lower social competence in both groups, but to more externalizing behaviors in DHH children only. DHH children in less linguistically accessible environments may not have adequate knowledge for appropriately expressing negative emotions socially.

Facial and Auditory Recognition Abilities of Implanted Primary Schoolers

OBJECTIVE

Emotions are often conveyed via visual and together with the auditory mode in social interaction. We aimed to investigate the ability to recognize facial and/or auditory emotions in school-aged children with cochlear implantation and healthy controls.

METHODS

All participants were asked to respond to facial emotions of Ekman and Friesen's pictures, then auditory emotions, and last, they were asked to respond to video-based dynamic synchronous facial and auditory emotions.

RESULTS

The mean accuracy rates in recognizing anger (p = 0.025), surprise (p = 0.029), and neutral (p = 0.029) faces were significantly worse in children with cochlear implants (CIs) than in healthy controls. They were significantly worse than healthy controls in recognizing all auditory emotions except auditory emotion of fear (p = 0.067). The mean accuracy rates in recognizing video-based auditory/facial emotions of surprise (p = 0.031) and neutral (p = 0.029) emotions were significantly worse in children with CIs.

CONCLUSION

The children with hearing loss were poorer in recognizing surprise, anger, and neutral facial emotions than healthy children; they had similar performance in recognizing anger emotions when both stimuli were given synchronously which may have a positive effect on social behaviors. It seems beneficial that emotion recognition training should be included in rehabilitation programs.

The Roles of Shame and Guilt in the Development of Aggression in Adolescents With and Without Hearing Loss

This longitudinal study examined how shame and guilt contribute to the development of reactive and proactive aggression in adolescents with and without hearing loss. Adolescents between 9 and 16 years old (adolescents with hearing loss (n = 80; Mage = 11.91) and without hearing loss (n = 227; Mage = 11.63)) completed self-reports on three occasions with an interval of 9 months. Mixed model analyses revealed that both reactive aggression and proactive aggression decreased with age, whereas shame and guilt peaked in early adolescence. Adolescents with hearing loss reported higher levels of proactive aggression, lower levels of shame and guilt, and showed protracted development for guilt compared to their hearing peers. In both groups, shame contributed to an increase in reactive aggression, whereas guilt contributed to a decrease in proactive aggression. These longitudinal associations highlight the unique role that shame and guilt play in the development of adolescent aggression.

Influence of family environment on the outcomes of cochlear implantation in pediatric recipients

Objectives:

To determine whether family environment and demographic factors such as family income and education produce any significant difference in postoperative performance of cochlear implant (CI)patients.

Methods:

In this study, 49 participants who received cochlear implant devices at King Abdullah Ear Specialist Center, Riyadh, Saudi Arabia before the age 5 years were included. Data were collected between July 2019 and August 2019. Postoperative performance was assessed by speech intelligibility rating (SIR) and categories of auditory performance (CAP) scales. Family environment was assessed with family environment scale (FES) survey. Data of demography, average income, and maternal and paternal education were obtained through review of patient’s medical files. The data obtained were analyzed using Statistical Package for Social Sciences for Mac, version 23 (IBM Corp, Armonk, NY, USA).

Results:

A significant difference between the organization categories of FES (p<0.05) was observed in terms of postoperative CAP scores, while a significant effect of the expressiveness category on both postoperative CAP and SIR scores (p<0.05) was observed. The scores on both CAP and SIR scales were significantly affected by maternal education, and the scores on SIR scale were positively correlated with paternal education.

Conclusion:

This study suggests that post-procedural performance of auditory perception and speech intelligibility in CI patients is significantly related to the family environment as well as the education levels of the parents.

The influence of cochlear implantation on aggression behaviors in children

OBJECTIVE

It has been suggested that children with higher degree of hearing loss may show more severe externalizing (e.g., aggression) and internalizing (e.g., depression and anxiety) behavioral problems compared to that of their normally hearing peers. The purpose of this study was to investigate the influence of sound amplification through cochlear implants (CIs) on aggressive behaviors in Persian children.

METHODS

During a prospective study design, 72 children (40 girls, 32 boys) who underwent unilateral implantation and 72 (40 girls, 32 boys) age-matched normally hearing children (control group) participated. All CI children had age of <4 years at the time of implantation. The Aggression Scale for Preschoolers (ASFP) was utilized to measure various types of aggression including verbal aggression, physical aggression, relational aggression, and impulsive anger. The speech performance of children was also evaluated using Speech Intelligibility Rating (SIR). The ASFP and SIR measurements were conducted at the pre-implantation phase and at 6, 12, and 18 months post-implantation period.

RESULTS

A repeated measures analysis of variance showed significant reduction in ASFP scores from "pre-operation" to "post-operative" conditions in CI group. However, aggression level in CI recipients were significantly higher than children in control group. In the analyses of ASFP subscales, we found a reduction and a consequent improvement in verbal aggression, physical aggression and impulsive anger. However, no significant difference was found in relational aggression across various time intervals. Furthermore, children who received CI before 2 years old exhibited better aggression level than children who received their devices at later ages. The significantly negative correlation (r = -0.76, p < 0.001) was found between the SIR and ASFP scores, so that lower speech intelligibity ability scores were associated with more aggressive behavior problems.

CONCLUSION

This study suggests that young children with noticeable degree of hearing loss may experience higher level of aggression compared to normally hearing peers. However, when they undergo early implantation and attend at regular post-operative rehabilitation programs, their aggression status will improve seriously.

Development of auditory and language skills in children using cochlear implants with two signal processing strategies

Introduction

The increase in the spectral information offered by the sound processing strategy HiRes 120 has led to great expectations for the pediatric population. Due to a shorter duration of auditory deprivation and higher neural plasticity, children could benefit more substantially from the spectral information of this sound processing strategy.

Objective

To compare auditory and language skills in Brazilian children with cochlear implants using the HiRes and HiRes 120 sound processing strategies.

Methods

Thirty children, aged 1–3 years, with congenital hearing loss, were divided into two groups, according to the signal processing strategy adjusted at the time of the cochlear implant activation. The assessed children were matched according to chronological age and the time of the cochlear implant use. The auditory and language skills were evaluated longitudinally through the Infant-Toddler Meaningful Auditory Integration Scale and Production Infant Scale Evaluation, carried out before surgery, and 3, 6 and 12 months after device implantation. The Mann–Whitney test was applied for the comparison between the two groups with a 5% significance level.

Results

The findings indicated development of hearing and language skills in the first year of cochlear implant use; however, there was no statistically significant difference in the evolution of such skills due to the adjusted processing strategy in the activation of the cochlear implant electrodes.

Conclusion

The development of auditory and language skills in the assessed children was similar during the entire study period, regardless of which signal processing strategy was used.

Frequencies of Behavioral Problems Reported by Parents and Teachers of Hearing-Impaired Children With Cochlear Implants

Background: Internalizing and externalizing behavioral problems were frequently reported in profoundly hearing-impaired (HI) children with hearing aids. Due to the positive effect of cochlear implants (CIs) on hearing and language development, a positive effect on behavioral problems was expected. However, there is no consensus about the frequency of behavioral problems in CI children, and studies are often based on one informant with the risk of missing behavioral problems in other contexts. Aims: The first aim of this study was to investigate the frequency of behavioral problems in children with CIs as compared to a hearing normative sample. The second aim was to measure the agreement between the parents' and teachers' rates on the behavioral problem scales. And the third aim was to investigate the relation between speech perception, language skills and the frequencies of reported behavioral problems. Methods: Of 71 CI children, 51% were girls and 49% were boys, and the mean age was 8.6 (SD = 3.3). Behavior was reported by parents using the Child Behavior Checklist (CBCL) and by teachers using the Teacher Report Form (TRF). Frequencies of behavioral problems of CI children (6-16 years) were compared to a normative sample with the chi square test. Parent-teacher agreement was measured with the intraclass correlation coefficient (ICC 2,1). Next CI children were divided into four ability level categories regarding speech perception and language skills. Frequencies of behavioral problems were compared between the categories with the chi square test. Results: Parents and teachers of CI children reported similar frequencies of behavioral problems to the normative sample. Fair to low parent-teacher agreements were found on the behavioral problem scales. A significantly higher frequency of behavioral problems was reported in children with low speech perception and receptive vocabulary at school. Conclusion: Parents and teachers report similar frequencies of behavioral problems children with CIs compared to a hearing normative sample. Children with lower speech perception and language levels are more at risk of developing behavioral problems at school. Adequate speech perception and language levels are found to be protective factors for the development of behavior.

Assessment and Treatment of Behavioral Disorders in Children with Hearing Loss: A Systematic Review

OBJECTIVE

There is evidence that children who are deaf and hard of hearing (DHH) have a higher incidence of behavioral disorders. Assessment of behavioral health in this population is often complicated by language developmental delays, which may result in unrecognized and untreated behavioral problems. The purpose of this study is to assess the association of behavioral disorders among children who are DHH and to explore behavioral interventions for children in this population.

DATA SOURCES

PubMed, CINALH, PsychINFO, and Web of Science.

REVIEW METHODS

Search terms included the following: problem behavior, child behavior disorders/diagnosis, child behavior disorders/psychology coupled with hearing loss, cochlear implants, hearing aids, or deafness. Studies from the last 30 years (1985-2016) were included. The articles were reviewed independently by 3 reviewers.

RESULTS

Thirty-six articles met criteria. There was an association between internalizing behaviors and hearing loss among children, which may persist after cochlear implantation. These problems may be more pronounced for children with additional disabilities. Conduct and hyperactivity disorders as well as emotional and executive function problems among children who are DHH may be related to poor language development. There was limited evidence regarding interventions to address the behavioral disorders of DHH children.

CONCLUSIONS

There is a significant body of evidence demonstrating behavioral problems among DHH children but a lack of clear understanding of the mechanisms involved. There is limited evidence on interventions to address the behavioral problems of DHH children. Future research is warranted to mitigate the long-term effects of disruptive behavior among these children.

Vocal Emotion Identification by Children Using Cochlear Implants, Relations to Voice Quality, and Musical Interests

PURPOSE

Listening tests for emotion identification were conducted with 8-17-year-old children with hearing impairment (HI; N = 25) using cochlear implants, and their 12-year-old peers with normal hearing (N = 18). The study examined the impact of musical interests and acoustics of the stimuli on correct emotion identification.

METHOD

The children completed a questionnaire with their background information and noting musical interests. They then listened to vocal stimuli produced by actors (N = 5) and consisting of nonsense sentences and prolonged vowels ([a:], [i:], and [u:]; N = 32) expressing excitement, anger, contentment, and fear. The children's task was to identify the emotions they heard in the sample by choosing from the provided options. Acoustics of the samples were studied using Praat software, and statistics were examined using SPSS 24 software.

RESULTS

The children with HI identified the emotions with 57% accuracy and the normal hearing children with 75% accuracy. Female listeners were more accurate than male listeners in both groups. Those who were implanted before age of 3 years identified emotions more accurately than others (p < .05). No connection between the child's audiogram and correct identification was observed. Musical interests and voice quality parameters were found to be related to correct identification.

CONCLUSIONS

Implantation age, musical interests, and voice quality tended to have an impact on correct emotion identification. Thus, in developing the cochlear implants, it may be worth paying attention to the acoustic structures of vocal emotional expressions, especially the formant frequency of F3. Supporting the musical interests of children with HI may help their emotional development and improve their social lives.

Current trends in outcome studies for children with hearing loss and the need to establish a comprehensive framework of measuring outcomes in children with hearing loss in China

Since the 1970s, outcome studies for children with hearing loss expanded from focusing on assessing auditory awareness and speech perception skills to evaluating language and speech development. Since the early 2000s, the multi-center large scale research systematically studied outcomes in the areas of auditory awareness, speech-perception, language development, speech development, educational achievements, cognitive development, and psychosocial development. These studies advocated the establishment of baseline and regular follow-up evaluations with a comprehensive framework centered on language development. Recent research interests also include understanding the vast differences in outcomes for children with hearing loss, understanding the relationships between neurocognitive development and language acquisition in children with hearing loss, and using outcome studies to guide evidence-based clinical practice. After the establishment of standardized Mandarin language assessments, outcomes research in Mainland China has the potential to expand beyond auditory awareness and speech perception studies.
