Phonemic awareness and early spelling skills in urban Australian Aboriginal and non-Aboriginal children

Features of culturally and linguistically relevant speech-language assessments for Indigenous children: A scoping review

INTRODUCTION

Indigenous children may be at higher risk of being misdiagnosed with speech-language difficulties due to Eurocentric practices in health care and education. The use of conventional speech pathology assessment practices contributes to inappropriate disorder identification, further stigmatising a vulnerable population. Few resources are available for speech pathologists, which examine the cultural and linguistic relevance of assessments for this population.

OBJECTIVE

To provide important features for speech pathologists to account for when building assessment plans for Indigenous children.

DESIGN

This comprehensive scoping literature review was completed using the Arksey and O'Malley 6-step methodological framework, including the optional consultation exercise, and reported using the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines. To be included, studies needed to have been published since 2000, discuss speech-language assessments and involve a significant proportion of Indigenous participants under 7 years old.

FINDINGS

Three features were extracted from 32 studies that discussed First Nations, Métis, Inuit, Native American, Aboriginal and Torres Strait Islander communities: using a battery of resources including alternative approaches, ensuring authenticity and cultural relevance, and considering a child's linguistic characteristics.

CONCLUSION

While there remains a need to adapt according to a specific child's reality, this study provides a guideline for all allied health clinicians when they are building their culturally and linguistically relevant assessment plans.

Binaural processing and phonological awareness in Australian Indigenous children from the Northern Territory: A community based study

OBJECTIVE

Research has found that otitis media (OM) is highly prevalent in Australian Indigenous children, and repeated bouts of OM is often associated with minimal-to-moderate hearing loss. However, what is not yet clear is the extent to which OM with hearing loss impacts auditory signal processing specifically, but also binaural listening, listening in noise, and the potential impact on phonological awareness (PA) - an important, emergent literacy skill. The goal of this study was to determine whether auditory abilities, especially binaural processing, were associated with PA in children from populations with a high incidence of OM, living in a remote Australian Indigenous community in the Northern Territory (NT).

METHODS

Forty-seven 5-12-year-olds from a bilingual school participated in the study. All were tested to determine hearing sensitivity (pure tone audiometry and tympanometry), with PA measured on a test specifically developed in the first language of the children. OM often results in a hearing loss that can affect binaural processing: the Dichotic Digit difference Test (DDdT) was used to evaluate the children's dichotic listening and the Listening in Spatialized Noise-sentences test (LiSN-S) was used to evaluate their abilities to listen to speech-in-noise.

RESULTS

Seventeen (36%) and 16 (34%) had compromised middle ear compliance (combined Type-B and -C) in the right and left ear respectively. Six children demonstrated a bilateral mild hearing loss, and another five children demonstrated a unilateral mild hearing loss. Thirty-one children were able to complete the DDdT listening task, whereas only 24 completed the speech in noise task (LiSN-S). Forty-four children (94%) were able to complete the letter identification subtask, comprising part of the PA task. The findings revealed that age was significantly correlated with all tasks such that the older children performed better across the board. Once hearing thresholds were controlled for, PA also correlated significantly with both binaural processing tasks of dichotic listening (r = 0.59, p < 0.001) and listening to speech in noise (r = -0.56, p = 0.005); indicating a potential association between early, emergent literacy and listening skills.

CONCLUSIONS

The significant correlations between phonological awareness and dichotic listening as well as phonological awareness with listening to speech-in-noise skills suggests auditory processing, rather than hearing thresholds per se, are associated to phonological awareness abilities of this cohort of children. This suggests that the ability to process the auditory signal is critical.

Comparing the spelling and reading abilities of students with cochlear implants and students with typical hearing

The purpose of this study was to determine whether students with and without hearing loss (HL) differed in their spelling abilities and, specifically, in the underlying linguistic awareness skills that support spelling ability. Furthermore, we examined whether there were differences between the two groups in the relationship between reading and spelling. We assessed the spelling, word-level reading, and reading comprehension skills of nine students with cochlear implants and nine students with typical hearing who were matched for reading age. The students' spellings were analyzed to determine whether the misspellings were due to errors with phonemic awareness, orthographic pattern or morphological awareness, or poor mental graphemic representations. The students with HL demonstrated markedly less advanced spelling abilities than the students with typical hearing. For the students with HL, the misspellings were primarily due to deficiencies in orthographic pattern and morphological awareness. Correlations between measures of spelling and both real word reading and reading comprehension were lower for the students with HL. With additional investigations using a similar approach to spelling analysis that captures the underlying causes for spelling errors, researchers will better understand the linguistic awareness abilities that students with HL bring to the task of reading and spelling.

Nutritional status of haemodialysis patients: comparison of Australian cohorts of Aboriginal and European descent

AIM

It is not known whether nutritional status differs between Australian Aboriginal and non Aboriginal haemodialysis subjects. The aim of this study was to investigate the nutritional status of Australian Aboriginal and non-Aboriginal haemodialysis subjects at satellite dialysis centres.

METHOD

Seventy-six (25 Aboriginal, 51 non-Aboriginal) prevalent haemodialysis patients were enrolled in a 3-month cross-sectional study. Each month anthropometric and biochemical measurements were collected. Nutritional status (diet history, patient-generated subjective global assessment (PG-SGA), handgrip strength) was assessed by a dietitian.

RESULTS

PG-SGA detected mild to moderate malnutrition in 35% of Aboriginal patients and 25% of non-Aboriginal patients. The overall physical rating on the PG-SGA was significantly higher in Aboriginal patients, indicating the presence of a greater deficit in muscle mass in this population. Inter-dialytic weight gain was significantly greater in Aboriginal subjects (median [range] 3.0 [2.1-5.7] vs 2.5 [-0.3-5.0] kg, P<0.001). Glucose and HbA1c were significantly higher in Aboriginal subjects with diabetes than in non-Aboriginal patients with diabetes (median [range] 9.4 [4.9-23.4] vs 5.7 [3.1-12.9], P=0.002; 7.0 [5.2-11.0] vs 5.8 [4.6-9.0], P<0.000; respectively). These findings occurred in the setting of each cohort having adequate dialysis parameters (median Kt/V of >1.6 and median normalized protein catabolic rate 1.5). Difficulties were encountered in obtaining dietary information from Aboriginal subjects using the diet history method.

CONCLUSION

Subjects had acceptable parameters of dialysis adequacy; however, 35% had evidence of malnutrition. Further research should focus on establishing a knowledge base for the nutritional management for Aboriginal dialysis subjects, and the development of a validated individual dietary assessment method for use in this population group.

Literacy skills of Australian Indigenous school children with and without otitis media and hearing loss

This study examined the relationship between reading, spelling, and the presence of otitis media (OM) and co-occurring hearing loss (HL) in metropolitan Indigenous Australian children, and compared their reading and spelling outcomes with those of their non-Indigenous peers. OM and HL may hinder language development and phonological awareness skills, but there is little empirical evidence to link OM/HL and literacy in this population. Eighty-six Indigenous and non-Indigenous children attending pre-primary, year one and year two at primary schools in the Perth metropolitan area participated in the study. The ear health of the participants was screened by Telethon Speech and Hearing Centre EarBus in 2011/2012. Participants' reading and spelling skills were tested with culturally modified sub-tests of the Queensland University Inventory of Literacy. Of the 46 Indigenous children, 18 presented with at least one episode of OM and one episode of HL. Results indicated that Indigenous participants had significantly poorer non-word and real word reading and spelling skills than their non-Indigenous peers. There was no significant difference between the groups of Indigenous participants with OM and HL and those with normal ear health on either measure. This research provides evidence to suggest that Indigenous children have ongoing literacy development difficulties and discusses the possibility of OM as one of many impacting factors.

The use of a standardized language assessment tool to measure the language development of urban Aboriginal preschoolers

The use of standardized language assessment tools with Australian Indigenous children has been criticized for language and cultural reasons; however, this has not been tested in an urban context. The aim of the study was to explore the language performance of a small sample of urban Aboriginal preschoolers on a standardized language tool compared with a conversational sample. Fifteen participants (drawn from a birth cohort study of over 150 Aboriginal infants born at a metropolitan hospital) completed the Clinical Evaluation of Language Fundamentals-Preschool Edition, Second Edition (CELF-P2) and generated a 30-minute conversational language sample. Descriptive data are reported, and five case studies are explored in detail to compare results of the CELF-P2 and the language sample analysis. Grammatical features of Aboriginal English are also investigated. There was a diverse range of responses to standardized assessment and language sampling, with some samples reflective of CELF-P2 results. Two or more grammatical features of Aboriginal English were identified in 13 of the language samples. The results suggest the CELF-P2 is an appropriate tool to use to assess the language development of the children in the study when used in conjunction with analysis of language samples obtained using culturally appropriate methods.

The cultural appropriateness and diagnostic usefulness of standardized language assessments for Indigenous Australian children

Speech-language pathologists experience uncertainty about how to interpret standardized assessment results for Indigenous Australian children. There are risks for inappropriate diagnosis: both over- and under-diagnosis of language impairment may occur due to a convergence of linguistic features which causes difficulty in distinguishing between impairment and difference. While the literature suggests that standardized assessments are inappropriate for Indigenous Australian children, there is an absence of empirical documentation to show how Indigenous children perform on standardized tests of language ability. This study examined the performance of 19 Indigenous Australian children, aged 8;01-13;08, from one school on the Clinical Evaluation of Language Fundamentals, Fourth Edition, Australian Standardized Edition. Standardized scores were compared with teacher ratings of children's oral language skills. Analysis showed poor alignment between teacher ratings and language assessment, and assessment scores were negatively influenced by features of Aboriginal English. Children rated with above average language skills presented with different linguistic profiles from the children rated with average and below average language abilities. The inappropriateness of current standardized language assessments for Indigenous children and the need for further research to guide appropriate assessment are discussed.

Responding to the World Report on Disability in Australia: lessons from collaboration in an urban Aboriginal and Torres Strait Islander school

The timely release of the World Report on Disability serves as a challenge to members of the health professions to review and renew their response to inequity of access and provision of services to children and adults with a disability. This paper responds to the lead article by Wylie, McAllister, Davidson, and Marshall, and provides commentary on two of the recommendations of the World Report on Disability in the context of a novel inter-professional service for Aboriginal and Torres Strait Islander children with communication and learning needs. Speech-language pathology and occupational therapy students reported on their learning within a model of service delivery based on partnership with an Aboriginal and Torres Strait Islander school community and inter-professional collaboration. Lessons learned have the potential to inform future services for under-served populations and to impact on capacity building through health professionals gaining experiential knowledge and understanding of an urban Aboriginal and Torres Strait Islander community.
