Suitability of vocabulary assessments : comparing child scores and parent perspectives on communicative inventories for Aboriginal families in Western Sydney

Purpose: Standardised testing tools within an Aboriginal Australian context have been found to produce inaccurate results due to language and cultural differences. The primary aim of the study is to compare Aboriginal children's scores in urban NSW across two language assessment tools: the Early Language Inventory (ERLI) and the Australian English Communicative Development Inventory, short form (OZI-SF). These tools are vocabulary checklists for children aged approximately 12-30 months. OZI-SF is an Australian tool for mainstream use and ERLI has been developed with and for Aboriginal families, but not in urban contexts, so its suitability there is unknown, given the great cultural and linguistic diversity among Aboriginal people across Australia. The second aim is to identify which tool is more culturally appropriate for urban Aboriginal families through parent perspectives. Method: Overall, 30 parents (of 31 children) participated in the study to complete the ERLI, and 14 parents from this sample completed both the ERLI and OZI-SF and interviews to explore child scores and parent perspectives, in a mixed methods approach. Result: Aboriginal children (N = 14) scored higher on the ERLI than the OZI-SF. Gender and age were significant contributors to the scores as scores were higher for older children and higher for girls than boys. In answer to the second aim, four themes emerged to explain parental perspectives and their preference for the ERLI, which supported connection to culture and language. Conclusion: Findings have implications for paediatric language assessments with urban Aboriginal families in clinical, educational and research settings.
