Vocabulary skills of school-age children with acquired brain injury: an exploration of tiered word knowledge and naming errors.

BACKGROUND: Vocabulary deficits are the most frequently documented communication difficulty following childhood acquired brain injury (ABI). Given the adverse consequences of limited vocabulary on academic success, it is critical to identify the presence and nature of vocabulary impairments to provide effective intervention for children with ABI. METHOD: Eleven children (7;6-11;11) with moderate/severe ABI (>12 months post-injury) and individually matched typically developing (TD) controls completed an Australian adaptation of a vocabulary assessment based on a three-tiered framework: tier 1 (basic words), tier 2 (high-frequency, cross-curricular words), and tier 3 (curriculum-based words). Overall scores and tiered accuracy were compared at individual and group level. Type and frequency of expressive naming errors were also coded. RESULTS: In this pilot study, children with ABI demonstrated poorer overall scores than TD children. Equivalent accuracy was noted for tier 1 words and tier 2 receptive words. However, significantly poorer accuracy was noted in the ABI group for tier 2 expressive words and all tier 3 words. The majority of naming errors were semantic across both groups although TD participants showed a wider distribution of error types. CONCLUSIONS: Findings support the use of tier 2 and 3 vocabulary as intervention targets in this population within education contexts and speech pathology settings.

Literacy Assessment Via Telepractice Is Comparable to Face-to-Face Assessment in Children with Reading Difficulties Living in Rural Australia.

Background/Introduction: Literacy difficulties have significant long-term impacts on individuals, and therefore early identification and intervention are critical. Access to experienced professionals who conduct standardized literacy assessments with children is limited in rural and remote areas. The emerging literature supports the feasibility of using telepractice to overcome barriers to accessing specialist literacy assessment. The current study sought to determine the feasibility and reliability of telepractice assessments, using consumer-grade technology, in children with reading difficulties. MATERIALS AND METHODS: Thirty-seven children, aged 8 to 12 years, with reading difficulties, attended a multidisciplinary reading clinic. Children completed literacy assessments delivered via a web-based application by a remotely located research assistant. A teacher was stationed with the child and coscored the assessments. Scores and qualitative observations of the two assessors were compared. RESULTS: Spearman's correlation analyses revealed strong agreement between telepractice- and face-to-face-rated scores (r = 0.79-0.99). Bland-Altman plots indicated excellent agreement between derived scores. Parents reported a high degree of comfort with the telepractice assessments. Clinicians reported the audio and video quality was sound in most cases. DISCUSSION/CONCLUSIONS: Web-based technology can enable remote delivery of literacy assessments. The technology has the potential to increase the availability of assessments to meet the needs of children who live remotely, in a timely manner and at their family's convenience.

Predictors of adaptive functioning in preschool aged children with autism spectrum disorder.

Difficulties in adaptive functioning are common in autism spectrum disorder (ASD) and contribute to negative outcomes across the lifespan. Research indicates that cognitive ability is related to degree of adaptive functioning impairments, particularly in young children with ASD. However, the extent to which other factors, such as socioeconomic status (SES) and ASD symptom severity, predict impairments in adaptive functioning remains unclear. The goal of this study was to determine the extent to which SES, ASD symptom severity, and cognitive ability contribute to variability in domain-specific and global components of adaptive functioning in preschool-aged children with ASD. Participants were 99 preschool-aged children (2-6 years) with ASD who attended a tertiary diagnostic service. Results demonstrate that cognitive ability accounted for a significant proportion of variance in domain-specific and global components of adaptive functioning, with higher cognitive ability predicting better adaptive functioning. Results also demonstrate that SES accounted for some variability in domain-specific communication skills and global adaptive functioning when compared to basic demographic factors alone (age and gender). By contrast, ASD symptom severity did not predict variability in domain-specific or global components of adaptive functioning. These findings provide support for a relationship between cognitive ability and adaptive functioning in preschool-aged children with ASD and help to explain specific contributions of verbal and nonverbal ability to adaptive functioning; from this, we can better understand which children are likely to show the greatest degree of impairments across components of adaptive functioning early in development. LAY SUMMARY: People with autism often have difficulties with everyday communication, daily living, and social skills, which are also called adaptive functioning skills. This study investigated factors that might be related to these difficulties in preschoolers with autism. We found that better cognitive ability, but not autism symptoms, were associated with better adaptive functioning. This suggests that interventions for young children with autism should take into account cognitive ability to better understand which children are likely to have difficulties with adaptive functioning.

The Acceptability and Efficacy of Electronic Data Collection in a Hospital Neurodevelopmental Clinic: Pilot Questionnaire Study.

BACKGROUND: There is a growing need for cost-efficient and patient-centered approaches to support families in hospital- and community-based neurodevelopmental services. For such purposes, electronic data collection (EDC) may hold advantages over paper-based data collection. Such EDC approaches enable automated data collection for scoring and interpretation, saving time for clinicians and services and promoting more efficient service delivery. OBJECTIVE: This pilot study evaluated the efficacy of EDC for the Child Development Unit, a hospital-based diagnostic assessment clinic in the Sydney Children's Hospital Network. Caregiver response rates and preference for EDC or paper-based methods were evaluated as well as the moderating role of demographic characteristics such as age, level of education, and ethnic background. METHODS: Families were sent either a paper-based questionnaire via post or an electronic mail link for completion before attending their first on-site clinic appointment for assessment. A total of 62 families were provided a paper version of the questionnaire, while 184 families were provided the online version of the same questionnaire. RESULTS: Completion rates of the questionnaire before the first appointment were significantly higher for EDC (164/184, 89.1%) in comparison to paper-based methods (24/62, 39%; P<.001). Within the EDC group, a vast majority of respondents indicated a preference for completing the questionnaire online (151/173, 87.3%), compared to paper completion (22/173, 12.7%; P<.001). Of the caregiver demographic characteristics, only the respondent's level of education was associated with modality preference, such that those with a higher level of education reported a greater preference for EDC (P=.04). CONCLUSIONS: These results show that EDC is feasible in hospital-based clinics and has the potential to offer substantial benefits in terms of centralized data collation, time and cost savings, efficiency of service, and resource allocation. The results of this study therefore support the continued use of electronic methods to improve family-centered care in clinical practices.

Neuropsychological outcomes of childhood acute necrotizing encephalopathy.

Acute necrotizing encephalopathy (ANE) is a rare form of acute encephalopathy, predominantly occurring in childhood, which has a typical radiological phenotype including bilateral, symmetrical, diffusion-restricted lesions of the thalami; posterior putamen; cerebellum; and brainstem. To date, no study has systematically examined the long-term cognitive and psychological impact of ANE. The current study describes the neuropsychological outcomes of three paediatric cases of ANE, ranging from 18 months to 10 years post ANE. All three cases displayed inattention, fine motor difficulties and anxiety. Social difficulties were also reported in all cases. The severity of long-term impairment was associated with acute presentation, as well as convalescent neuroimaging. These findings highlight the need for detailed neuropsychological assessment and long-term rehabilitation.

Agreement between telehealth and face-to-face assessment of intellectual ability in children with specific learning disorder.

INTRODUCTION: Access to cognitive assessments for children living remotely is limited. Telehealth represents a potential cost- and time-effective solution. A pilot study was conducted to determine the feasibility of telehealth to assess cognitive function in children with learning difficulties. METHODS: Thirty-three children (median age = 9 years 11 months), recruited from the New South Wales (NSW) Centre for Effective Reading, underwent assessment of intellectual ability. Comparisons were made between the intellectual ability index scores obtained by a psychologist sitting face-to-face with the children and another psychologist via telehealth using a web-based platform, Coviu. RESULTS: The telehealth administration method yielded comparable results to the face-to-face method. Correlation analyses showed high associations between the testing methodologies on the intellectual ability indices (correlation coefficient range = 0.981-0.997). DISCUSSION: Findings indicate that telehealth may be an alternative to face-to-face cognitive assessment. Future work in a broader range of cognitive tests and wider range of clinical populations is warranted.

Telehealth language assessments using consumer grade equipment in rural and urban settings: Feasible, reliable and well tolerated.

Introduction Telehealth can be an effective way to provide speech pathology intervention to children with speech and language impairments. However, the provision of reliable and feasible standardised language assessments via telehealth to establish children's needs for intervention and to monitor progress has not yet been well established. Further, there is limited information about children's reactions to telehealth. This study aimed to examine the reliability and feasibility of conducting standardised language assessment with school-aged children with known or suspected language impairment via a telehealth application using consumer grade computer equipment within a public school setting. Method Twenty-three children (aged 8-12 years) participated. Each child was assessed using a standardised language assessment comprising six subtests. Two subtests were administered by a speech pathologist face-to-face (local clinician) and four subtests were administered via telehealth. All subtests were completed within a single visit to the clinic service, with a break between the face to face and telehealth sessions. The face-to-face clinician completed behaviour observation checklists in the telehealth and face to face conditions and provided feedback on the audio and video quality of the application from the child's point of view. Parent feedback about their child's experience was elicited via survey. Results There was strong inter-rater reliability in the telehealth and face-to-face conditions (correlation coefficients ranged from r = 0.96-1.0 across the subtests) and good agreement on all measures. Similar levels of attention, distractibility and anxiety were observed in the two conditions. Clinicians rated only one session of 23 as having poor audio quality and no sessions were rated as having poor visual quality. Parent and child reactions to the use of telehealth were largely positive and supportive of using telehealth to assess rural children. Discussion The findings support the use of telehealth in the language assessment of school-aged children using a web application and commercially available computer equipment. This reliable and innovative service delivery model has the potential to be used by speech pathologists to provide assessments to children in remote communities.
