REACh for the preschoolers; a developmental assessment tool for 2-5 year old children in Sri Lanka. BMC Pediatr 2023; 23:80. [PMID: 36797694 PMCID: PMC9933303 DOI: 10.1186/s12887-023-03895-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/07/2021] [Accepted: 10/17/2022] [Indexed: 02/18/2023] Open
Abstract
BACKGROUND Preschool children in low resource settings are at higher risk of missing developmental potential due to the lack of standardized and validated methods for the timely detection of children with developmental delays or neurodevelopmental disorders. The preschool teacher is a non-specialist resourceful link within the community to detect and offer interventions early. This paper discusses the preliminary iteration of designing and testing the psychometric properties of a developmental assessment for children aged 24 to 60 months in Sri Lanka. This assessment is designed to be conducted by preschool teachers in their preschool setting. METHODS Three processes followed: 1. Designing and development of the Ragama Early Assessment for Children (REACh) complete preschool developmental assessment and a tool kit 2. Testing and training teachers on conducting the REACh assessment 3. Preliminary assessment of the psychometric properties including content validity, internal consistency, interrater reliability and concurrent validity. RESULTS A literature search identified 11 assessments and 542 items representing cognitive, social-emotional and adaptive, language and motor domains. Content validity was assessed to select and adapt items. A complete assessment tool was designed to be administered in four settings within the preschool. This was further improved during pre and pilot testing and teacher training. Cronbach's alpha measuring internal consistency was > 0.70 for cognitive, language, social-emotional and adaptive domains across all three age groups in 1809 children. Interrater reliability was > 65% for age groups 36-47 and 47- 60 months. Concurrent validity using a clinical gold standard demonstrated sensitivity of more than 0.75 for all age groups with variable specificities (24-35 months: 0.71, 36- 47 months: 0.43 and 48-60 months: 0.67) assessed in 75 children. CONCLUSIONS This culturally and linguistically adapted tool was tested nationally in Sri Lanka. The inte-rrater reliability between teachers and research assistants was higher than 65% for all domains in children more than 36 months. The preliminary iteration confirms it as an acceptable screening assessment for all age groups but with significantly lower specificity in the 36-47 month age group. Further improvement in certain domains together with intense teacher training is likely to enhance the validity and reliability of the assessment. TRIAL REGISTRATION Ethics clearance for the procedure was granted prospectively from the Ethics Review Committee, Faculty of Medicine, University of Kelaniya (ERC no. P 131/06/2018).

Abstract
OBJECTIVES The main objectives of this study were to translate and adapt the infant-toddler meaningful integration scale (IT-MAIS) into Arabic and to establish the psychometric properties of the translated scale in children with a cochlear implant. METHODS The translation and cross-cultural adaptation of this questionnaire were completed in multiple steps and following standard translation protocols. In total, twenty-eight parents of young cochlear implant recipients completed IT-MAIS. Data were collected postoperatively and at 3-, 6-, 9-, and 12-month post-device activation. Data were examined for the validity and reliability of the scale. The internal consistency and reliability of the scale were analyzed using Cronbach α, split-half reliability, and the corrected item-total correlation coefficients. RESULTS Findings demonstrated that the scale exhibited good face and content validity, suggesting that the scale is a one-dimensional measure. Additionally, the reliability analysis for the scale indicated high reliability and correlation among test items. IT-MAIS scores consistently improved over time for all participants and this improvement. correlated negatively with the duration of deafness. CONCLUSION Current findings indicated that the translated Arabic version of the IT-MAIS scale could serve as a valid instrument for assessing the development of auditory skills in Arabic-speaking children with cochlear implants.

Younger Age at Cochlear Implant Activation Results in Improved Auditory Skill Development for Children With Congenital Deafness. JOURNAL OF SPEECH, LANGUAGE, AND HEARING RESEARCH : JSLHR 2022; 65:3539-3547. [PMID: 36001854 PMCID: PMC9913281 DOI: 10.1044/2022_jslhr-22-00039] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/19/2022] [Revised: 04/27/2022] [Accepted: 06/04/2022] [Indexed: 06/01/2023]
Abstract
PURPOSE The U.S. Food and Drug Administration indications for cochlear implantation in children is currently 9 months of age and older for children with bilateral profound sensorineural hearing loss (SNHL). Studies have shown that earlier activation of a cochlear implant (CI) can lead to better spoken language outcomes. As auditory skills are a precursor to the development of spoken language, this study was developed to investigate the influence of age at CI activation on auditory skill acquisition in young children. A secondary aim was to describe the auditory skills of children implanted prior to 9 months of age as compared to children with older ages of activation. METHOD Functional Listening Index (FLI) scores obtained during routine clinical visits were reviewed for 78 pediatric CI recipients with congenital bilateral profound hearing loss who were activated before 2 years of age. A linear mixed-effects model assessed the effect of age at CI activation on cumulative FLI scores over time. RESULTS There was a significant interaction between age at activation and chronological age at the time of evaluation, indicating that children with earlier access to sound achieved a greater number of auditory skills than those with later CI activations when measured at the same chronological age. Children activated before the age of 9 months approximated scores expected of children with typical hearing, whereas children activated between 9 and 24 months of age did not. CONCLUSIONS Younger age at CI activation is associated with increased auditory skills over time. Children who undergo cochlear implantation and CI activation before 9 months achieve more auditory skills by 4 years of age than children who are activated at later ages. These data suggest that reducing the approved age at cochlear implantation for children with congenital bilateral profound SNHL may support optimal auditory skill acquisition.

Abstract
PURPOSE The purpose of this study was to comprehensively monitor the auditory skill development of children with hearing loss after hearing instrument fitting, and a battery of four assessments was proposed. METHOD This battery was designed to fill the gap in speech discrimination in clinically available evaluations. The battery includes both behavioral and neural assessments. On the other hand, both tests in structured settings (sound-treated booth) and daily life were included in the battery. The four assessments include visual reinforced infant speech discrimination (VRISD), cortical auditory evoked potentials (CAEP), Auditory Skills Checklist (ASC), and Parents' Evaluation of Aural/Oral Performance of Children (PEACH). RESULTS Two cases were reported, and their clinical implications were discussed. CONCLUSIONS The proposed comprehensive assessment battery is suitable for evaluating children who are developmentally appropriate for visual reinforcement audiometry. More importantly, the VRISD assessment fills in the current gap, which is the discrimination stage, for the available clinical tests for assessing auditory developmental stages.

Abstract
Objectives: To adapt the LittlEARS® Auditory Questionnaire into the Maltese language and evaluate the psychometric properties of the Maltese version of the questionnaire for hearing children. Methods: The English version of LittlEARS® Auditory Questionnaire was adapted into Maltese using a translation/back translation procedure. In this cross-sectional study, a total of 398 parents of normal hearing children aged between 5 days and 36 months completed the Maltese version of LittlEARS®. Psychometric validation was performed through scale analysis, item analysis, and analysis of reliability and validity. A non-linear regression model was derived to obtain normative data for expected and minimum values of total scores from the questionnaire according to age. Results: Predictive accuracy (Guttman’s lambda) was 0.921, the Cronbach’s alpha coefficient value was 0.921, and the split-half reliability coefficient was 0.949. The Pearson correlation coefficient between scores and age was 0.903. The regression analysis showed that 82% of the variance in the total scores can be explained by age. Norm curves were comparable to the original German data. Conclusion: This study confirmed that the Maltese version of LittlEARS® is a valid and reliable tool to evaluate auditory development in children less than two years of age.

Abstract
This article summarizes the available evidence on pediatric cochlear implantation to provide current guidelines for clinical protocols and candidacy recommendations in the United States. Candidacy determination involves specification of audiologic and medical criteria per guidelines of the Food and Drug Administration. However, recommendations for a cochlear implant evaluation also should maintain flexibility and consider a child’s skill progression (i.e., month-for-month progress in speech, language, and auditory development) and quality of life with appropriately fit hearing aids. Moreover, evidence supports medical and clinical decisions based on other factors, including (a) ear-specific performance, which affords inclusion of children with asymmetric hearing loss and single-sided deafness as implant candidates; (b) ear-specific residual hearing, which influences surgical technique and device selection to optimize hearing; and (c) early intervention to minimize negative long-term effects on communication and quality of life related to delayed identification of implant candidacy, later age at implantation, and/or limited commitment to an audiologic rehabilitation program. These evidence-based guidelines for current clinical protocols in determining pediatric cochlear implant candidacy encourage a team-based approach focused on the whole child and the family system.

Abstract
The purpose of this study was to consider how living in an area that qualifies for a rural health grant interacts with a child's hearing status to affect early language and literacy development. Four-year-old children with hearing aids (n = 45), cochlear implants (n = 47), and with typical hearing (n = 66) completed measures of spoken language knowledge and of emergent literacy skills as part of a larger longitudinal investigation. A significant interaction effect between location (rural or urban/suburban) and amplification group was detected for letter knowledge: children with hearing aids exhibit a performance that is particularly affected by rural location. Overall, children with cochlear implants performed lower across all measures than children with typical hearing, and children with hearing aids performed lower than children with typical hearing on measures of phonological awareness, vocabulary, omnibus language knowledge and articulation.

Int J Pediatr Otorhinolaryngol 2021; 148:110814. [PMID: 34214825 DOI: 10.1016/j.ijporl.2021.110814] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2021] [Revised: 06/14/2021] [Accepted: 06/24/2021] [Indexed: 11/28/2022]
Abstract
OBJECTIVES Monitoring children's development of auditory perception, speech and language after implant programming is critical to post-implantation success. Most of the time, it is not possible to perform an evaluation in clinical conditions, and the tests administered may not provide adequate data on children's everyday functional hearing skills. Therefore, administration of functional hearing measures alongside clinical tests will present supplementary data as to both language development and functional hearing performance of children. In addition, determining demographic and environmental variables affecting functional hearing skills and language development will facilitate the implementation of countermeasures. The main objective of this study was to investigate the relationship of functional hearing behaviors in cochlear-implanted children with semantics, morphology and syntax, and to determine how various variables affect functional hearing and language development. METHOD The study was conducted with 48 cochlear implant users (24 female and 24 male) aged between 3 years and 5 years 11 months with no additional disability. The Test of Early Language Development -Third Edition (TELD-3) was administered to the children participating in the study, and the Functioning after Pediatric Cochlear Implantation (FAPCI) and the demographic information form was completed pursuant to the information provided by the parents. RESULTS Data analysis in accordance with our hypotheses revealed a significant relationship between semantics, morphology, syntax and functional hearing skill (p < 0.05). The results indicated that language development and functional hearing skill were positively affected by duration of implant use, duration of auditory rehabilitation and kindergarten attendance, and a negative relationship between screen time and functional hearing skill. CONCLUSIONS In conclusion, the FAPCI is a suitable measure for early listening development and language assessment after cochlear implantation surgery, providing supplementary data on functional hearing and language development when administered in conjunction with other tests. Many factors are affecting functional hearing and language development that determine cochlear implant success. It is important to identify these factors.

Abstract
Among the various cochlear implant systems approved by the Food and Drug Administration, current labeling for pediatric usage encompasses (1) bilateral profound bilateral sensorineural hearing loss in children aged 9 to 24 months and bilateral severe to profound sensorineural hearing loss in children older than 2 years; (2) use of appropriately fitted hearing aids for 3 months (this can be waived if there is evidence of ossification); and (3) demonstration of limited progress with auditory, speech, and language development. Pediatric guidelines require children to have significantly worse speech understanding before qualifying for cochlear implantation. The early years of life have been shown to be critical for speech and language development, and auditory deprivation is especially detrimental during this crucial time.Level of evidence: 2.

Abstract
OBJECTIVE The aim of this study is to investigate the development of auditory skills in Mandarin-speaking children with normal hearing using CAP-II, and to establish the baseline data for evaluating the auditory performance of children with hearing loss on which designs of appropriate hearing rehabilitation programs can be based. MATERIALS AND METHODS A total of 223 children participated in this study of which 200 children aged from 1 to 60 months were finally included. Their normal hearing was confirmed by examination of hearing history and high-risk registers for hearing loss, as well as by hearing screening. All children were divided into 10 groups with 20 children in each group based on age. The CAP-II scale was administered to evaluate their development of auditory skills. RESULTS The categories of auditory performance scores of children with normal hearing improved with their age, the best-fit regression function for prediction of scores from age was Score = 0.94 × ln(age) + 0.08 × (age) + 1.16 and prediction of age from score was Age = 0.65 × (score)2-0.14 × (score)-0.23. The overall CAP-II scale exhibited good reliability and validity. CONCLUSIONS and Significance: An improvement in auditory skill with age in children with normal hearing was observed. Ceiling performance in auditory skills was found at the age of 51 months for normal children. A conversion table between age and scores obtained from the data of this study can be used as a reference for the assessment of clinical hearing ability in children.

Abstract
INTRODUCTION Audition is the gateway to spoken language, and infants' early accomplishments in acquiring the sound structure of their native language lays a critical ground work for subsequent learning. The development of pre-lingual auditory perceptual skills for cochlear implanted children is crucial for initial development of oral language. OBJECTIVE The aims of the present study were to validate the Egyptian Arabic Assessment of Auditory Skills, and to track the development of auditory skills in Egyptian children fitted with CI during the first three years post implantation. METHODS The study included 90 Arabic Egyptian children attending the phoniatric unit, Kasr El Aini hospital. Their chronological age ranged from 36 to 72 months. The study lasted for 18 months from July 2015 to January 2017. The children were divided into six groups according to their cochlear age i.e., amount of implant experience. An Arabic assessment chart of auditory skills was tailored that included six auditory skills' domains; detection, identification, short term auditory memory, supra-segmental discrimination, segmental discrimination and linguistic auditory processing. This chart was then used to develop an assessment tool which was then applied to all the study participants. All children had bilateral Sensorineural Hearing Loss (SNHL) since birth. None of the participants had prior Cochlear Implant (CI), but all had tried conventional hearing aids. All participants were implanted unilateral, with CI devices. All met selection criteria applied in the Egyptian national insurance committee for cochlear implantation. RESULTS All auditory skills domains improved with cochlear age. There was significant improvement between 1-6 and 7-12 months in the scores of the Detection (DET) domain. There was significant difference between 1-6 and 7-12 months, 7-12 and 13-18 months, 19-24 and 25-30 months in the scores of the Identification (IDENT) domain. Regarding the Short Term Auditory Memory (STAM) domain scores and the Supra-segmental Discrimination (SSD) domain scores there was significant difference between all the groups. Regarding the Segmental Discrimination (SGD) domain scores, there was significant difference between group 1-6 and 7-12 months, 7-12 and 13-18 months, 19-24 and 25-30 months, 25-30 and 31-36 months. Regarding the Linguistic Auditory Processing (LAP) domain, there was significant difference between group 1-6 and 7-12 months, 7-12 and 13-18 months, 25-30 and 31-36 months. CONCLUSIONS Children fitted with Cochlear Implants (CIs) appeared to show improvement in acquisition of auditory skills over a period of three years that followed a hierarchy of development dependent on the cochlear age.

Abstract
PURPOSE This study investigates differences between preschool children with cochlear implants and age-matched children with normal hearing during an initial stage in word learning to evaluate whether they (a) match novel words to unfamiliar objects and (b) solicit information about unfamiliar objects during play. METHOD Twelve preschool children with cochlear implants and 12 children with normal hearing matched for age completed 2 experimental tasks. In the 1st task, children were asked to point to a picture that matched either a known word or a novel word. In the 2nd task, children were presented with unfamiliar objects during play and were given the opportunity to ask questions about those objects. RESULTS In Task 1, children with cochlear implants paired novel words with unfamiliar pictures in fewer trials than children with normal hearing. In Task 2, children with cochlear implants were less likely to solicit information about new objects than children with normal hearing. Performance on the 1st task, but not the 2nd, significantly correlated with expressive vocabulary standard scores of children with cochlear implants. CONCLUSION This study provides preliminary evidence that children with cochlear implants approach mapping novel words to and soliciting information about unfamiliar objects differently than children with normal hearing.

Abstract
BACKGROUND/AIMS Children with congenital cochleovestibular abnormalities associated with profound hearing loss have few treatment options if cochlear implantation does not yield benefit. An alternative is the auditory brainstem implant (ABI). Regulatory authority device approvals currently include a structured benefit-risk assessment. Such an assessment, for regulatory purposes or to guide clinical decision making, has not been published, to our knowledge, for the ABI and may lead to the design of a research program that incorporates regulatory authority, family, and professional input. METHODS Much structured benefit-risk research has been conducted in the context of drug trials; here we apply this approach to device studies. A qualitative framework organized benefit (speech recognition, parent self-report measures) and risk (surgery- and device-related) information to guide the selection of candidates thought to have potential benefit from ABI. RESULTS Children with cochleovestibular anatomical abnormalities are challenging for appropriate assessment of candidacy for a cochlear implant or an ABI. While the research is still preliminary, children with an ABI appear to slowly obtain benefit over time. A team of professionals, including audiological, occupational, and educational therapy, affords maximum opportunity for benefit. CONCLUSIONS Pediatric patients who have abnormal anatomy and are candidates for an implantable auditory prosthetic require an individualized, multisystems review. The qualitative benefit-risk assessment used here to characterize the condition, the medical need, potential benefits, risks, and risk management strategies has revealed the complex factors involved. After implantation, continued team support for the family during extensive postimplant therapy is needed to develop maximum auditory skill benefit.

Abstract
BACKGROUND Speech perception measures have long been considered an integral piece of the audiological assessment battery. Currently, a prelinguistic, standardized measure of speech perception is missing in the clinical assessment battery for infants and young toddlers. Such a measure would allow systematic assessment of speech perception abilities of infants as well as the potential to investigate the impact early identification of hearing loss and early fitting of amplification have on the auditory pathways. PURPOSE To investigate the impact of sensation level (SL) on the ability of infants with normal hearing (NH) to discriminate /a-i/ and /ba-da/ and to determine if performance on the two contrasts are significantly different in predicting the discrimination criterion. RESEARCH DESIGN The design was based on a survival analysis model for event occurrence and a repeated measures logistic model for binary outcomes. The outcome for survival analysis was the minimum SL for criterion and the outcome for the logistic regression model was the presence/absence of achieving the criterion. Criterion achievement was designated when an infant's proportion correct score was >0.75 on the discrimination performance task. STUDY SAMPLE Twenty-two infants with NH sensitivity participated in this study. There were 9 males and 13 females, aged 6-14 mo. DATA COLLECTION AND ANALYSIS Testing took place over two to three sessions. The first session consisted of a hearing test, threshold assessment of the two speech sounds (/a/ and /i/), and if time and attention allowed, visual reinforcement infant speech discrimination (VRISD). The second session consisted of VRISD assessment for the two test contrasts (/a-i/ and /ba-da/). The presentation level started at 50 dBA. If the infant was unable to successfully achieve criterion (>0.75) at 50 dBA, the presentation level was increased to 70 dBA followed by 60 dBA. Data examination included an event analysis, which provided the probability of criterion distribution across SL. The second stage of the analysis was a repeated measures logistic regression where SL and contrast were used to predict the likelihood of speech discrimination criterion. RESULTS Infants were able to reach criterion for the /a-i/ contrast at statistically lower SLs when compared to /ba-da/. There were six infants who never reached criterion for /ba-da/ and one never reached criterion for /a-i/. The conditional probability of not reaching criterion by 70 dB SL was 0% for /a-i/ and 21% for /ba-da/. The predictive logistic regression model showed that children were more likely to discriminate the /a-i/ even when controlling for SL. CONCLUSIONS Nearly all normal-hearing infants can demonstrate discrimination criterion of a vowel contrast at 60 dB SL, while a level of ≥70 dB SL may be needed to allow all infants to demonstrate discrimination criterion of a difficult consonant contrast.

Validation of the LittlEARS Auditory Questionnaire in cochlear implanted infants and toddlers. Int J Pediatr Otorhinolaryngol 2017; 93:107-116. [PMID: 28109480 DOI: 10.1016/j.ijporl.2016.12.024] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2016] [Revised: 12/20/2016] [Accepted: 12/21/2016] [Indexed: 11/22/2022]
Abstract
OBJECTIVES The LittlEARS Auditory Questionnaire (LEAQ) has so far been validated to assess auditory development in groups of normal-hearing children in over 20 different languages. Considering the huge variability in auditory development of CI children, especially since candidacy criteria have been relaxed, additional evidence to validate the use of LEAQ scores in this particular population is needed. The aim of this study is to provide evidence for the reliability and validity of LEAQ scores for assessing the auditory development of CI infants and toddlers based on an evaluation of LEAQ's internal structure and its relation to other variables. METHODS The study was prospective, with sequential enrolment and within-subject repeated measures. It included 122 children with profound bilateral sensorineural hearing loss implanted at 6-22 months of age. All children were evaluated with the Polish version of LEAQ on the first day of CI activation and at each of four follow-up visits related to sound processor fitting. The study was undertaken in the light of current psychometric thinking about how assessment instruments should be validated. The main aim of the study was to obtain evidence for the validity of interpreting LEAQ measures from CI children in terms of auditory development. First, in order to collect evidence for score reliability and validity based on LEAQ's internal structure, the psychometric properties of LEAQ scores from CI children were determined. A second step was to confirm validity by investigating the effect of concomitant variables on LEAQ scores. Correlations between LEAQ score and duration of hearing aid (HA) use, and between LEAQ score and duration of CI use, were investigated. Additionally, group differences in LEAQ scores between: 1) early and late implanted children; 2) children with long and short HA experience prior to implantation; and 3) children who showed responses over a wide frequency range from using their HAs (prior to implantation) vs those who did not. RESULTS On each of the five administrations of LEAQ, the item difficulty indices increased (meaning the items became easier) and over the series they progressively increased with a range of: 0.01-0.62, 0.03-0.92, 0.09-1.00, 0.26-1.00, and 0.52-1.00. At the same time, item-total correlations were in the ranges: 0.09-0.77, 0.26-0.62, 0.00-0.65, 0.00-0.65, and 0.00-0.67. Cronbach's alpha values were above 0.80 for all administrations. A positive correlation between LEAQ score and duration of HA use, and subsequent duration of CI use (hearing experience) was found. When the children were stratified into groups according to age at cochlear implantation, duration of HA use before implantation, and audibility provided by HAs prior to implantation, the differences between the groups were reflected in both their rate of auditory development and their LEAQ score. CONCLUSION The interpretation of LEAQ scores from CI children in terms of auditory development was supported by the validity evidence of internal structure and from a logical relationship to other variables. (1) Psychometric properties - item difficulty, item-total correlations, and Cronbach's alpha values - indicate that LEAQ measures are highly consistent and reliably gauge the level of a CI child's auditory development. (2) There was a positive correlation between LEAQ scores and the duration of hearing experience with HAs and a later CI; similarly, there were significant differences between groups of children stratified according to the age at cochlear implantation, duration of HA use before implantation, and audibility provided by HAs prior to implantation, all of which demonstrate the expected relation between LEAQ score and concomitant variables.

Abstract
Early identification and management of disabilities in children are essential to reduce long-term developmental sequelae. Many of the causes of hearing loss also produce cognitive delays resulting in a large number of children with both deafness and developmental disabilities. Children who have hearing loss and additional disabilities require complex, individualized therapy to maximize their long-term quality of life. Hearing loss is often detected early because of widespread newborn hearing screening programs and the decision for cochlear implantation in children presenting with multiple medical and developmental disorders is still evolving. This article will review the literature regarding cochlear implant considerations in children with additional developmental disabilities in areas of family perception, speech and language development, cognitive development including adaptive behavior and intelligence, communication and functional skills, auditory outcomes, quality of life outcomes, predictors of outcomes and realistic expectations after cochlear implantation.

Abstract
OBJECTIVE With more children receiving cochlear implants at an early age, there is a need for evaluation and assessment of early auditory behavior. We present the translation of the LittlEARS® Auditory Questionnaire into Hebrew and into Arabic. First the validation of the LittlEARS® Auditory Questionnaire in normal hearing children was evaluated. Second, the auditory behavior and the progress in hearing skills of a group of children with cochlear implants were assessed. METHODS A "back-translation" method was used to translate and adapt the LittlEARS® Auditory Questionnaire into Hebrew and into Arabic. Normal hearing participants included 70 Hebrew speaking and 97 Arabic speaking parents of children from 1 to 24 months of age with normal hearing. An additional group of 42 parents of children with cochlear implants with a hearing age of up to 24 months completed the LittlEARS® Auditory Questionnaire. 27 of them completed the questionnaire more than once at intervals, so that change and development could be recorded. Scores on the LittlEARS® Auditory Questionnaire were compared to results of SIR and CAP scales and other available auditory data. RESULTS The results of the first study show that the curves found for the Hebrew and the Arabic translations of the LittlEARS® Auditory Questionnaire are essentially similar to those previously found for other languages. These curves reflect the age dependency of auditory skills. Furthermore, in the group with cochlear implants the developmental pattern was different than that of the normal hearing group, with an initial steep increase and a later slower improvement. This trend appeared both in curves of groups and in curves of individuals (individuals whose parents completed the questionnaire at several points in time). There was a high correlation between scores on the LittlEARS® Auditory Questionnaire and results of other audiologic tests, showing validity of results with the LittlEARS® Auditory Questionnaire. CONCLUSION Both the Hebrew and Arabic versions of the LittlEARS® Auditory Questionnaire were found to be reliable and valid tools for assessment of the development of auditory behavior in children up to the age of 24 months. Furthermore, the LittlEARS® Auditory Questionnaire in both languages is useful in monitoring the progress of children with cochlear implant.

Abstract
BACKGROUND AND AIMS Newborn hearing screening and early intervention for congenital hearing loss have created a need for tools assessing the hearing development of very young children. A multidisciplinary evaluation of children's development is now becoming standard in clinical practice, though not many reliable diagnostic instruments exist. For this reason, the LittlEARS Auditory Questionnaire (LEAQ) was created to assess the auditory skills of a growing population of infants and toddlers who receive hearing instruments. The LEAQ relies on parent report, which has been shown to be a reliable way of assessing child development. Results with this tool in a group of children who received very early cochlear implantation are presented. METHODS The LEAQ is the first module of the LittlEARS comprehensive test battery for children under the age of two who have normal hearing (NH), cochlear implants (CIs) or hearing aids (HAs). The LEAQ is a parent questionnaire comprised of 35 "yes/no" questions which can be completed by parents in less than 10 min. Sixty-three children who received unilateral CIs at a young age were assessed longitudinally and their performance was compared to that of a NH group. RESULTS All CI children reached the maximum possible score on the LEAQ on average by 22 months of hearing age, i.e. 38 months of chronological age. In comparison, the NH group reached the maximum score by 24 months of age demonstrating that auditory skills of CI children often develop quicker than those of NH children. In the two comparison groups of children aged (a) younger and older than 12 months, and (b) between 6-9 and 21-24 months at first fitting, the early implanted children reached the highest scores faster than the later implanted children. Furthermore, three children with additional needs were tested. They showed slower growth over time but also received benefits from early implantation. CONCLUSIONS The LEAQ is a quick and effective tool for assessing auditory skills of very young children with or without hearing loss. In our study, the auditory skills of children with CI progressed very quickly after implantation and were comparable with those of NH peers.

Abstract
CONCLUSION Most of the infants demonstrated rapid improvement in the three different auditory skills within the first year after switch-on. Infants undergoing hearing aid trial and habilitation demonstrated a significant positive effect on the development of auditory skills in comparison with infants without trial and habilitation. OBJECTIVE This paper aims to evaluate the auditory performance of infants of different age at cochlear implantation, emphasize the importance of the hearing aid trial and habilitation before implant, and provide baseline data of auditory development. METHODS In all, 259 infants with prelingually profound hearing loss participated in this study. The Infant-Toddler Meaningful Auditory Integration Scale (IT-MAIS) was used to assess auditory skills in infants at different intervals. RESULTS The mean scores for the auditory skills improved significantly over time. The mean scores of three skills for each group at each interval were significantly different. The mean scores of the auditory skills were significantly superior for infants undergoing hearing aid trial and habilitation in comparison with those of infants without hearing aid trial and habilitation.

Abstract
Objectives: We sought to understand auditory skills outcomes in young children with cochlear implants and developmental delay. Methods: Children who received cochlear implants at less than 36 months of age were identified via chart review. Their postimplant auditory skills outcomes were measured with the Auditory Skills Checklist. Results: Of 35 children who received cochlear implants before the age of 36 months, 14 children (40%) had additional disabilities or some form of developmental delay. The 12-month postimplant data indicated progress in all groups of children. Children with additional disabilities had the same rate of auditory skills progress as children with no additional disabilities (β = 9.3 versus 9.3; p = 0.5). However, the children with additional disabilities tended to start at a lower baseline skills set (approximately 6 points lower) on the Auditory Skills Checklist. For children with average developmental quotients (at least 80), the rate of progress was twice that of children with a developmental quotient of less than 80, irrespective of a developmental disability (β = 9.9 versus 4.8; p = 0.03). Children with a developmental quotient of less than 80 were less likely to gain skills in discrimination and identification after the first postimplant year. Conclusions: Children with additional disabilities make progress in auditory skills, but may not develop higher auditory skills of identification and comprehension within the first 6 months after implantation. Categorizing children according to a cognitive developmental quotient may provide more predictive ability than does categorizing them by disability type.
