Intellectual disability and autism prevalence in Western Australia: impact of the NDIS

Introduction

Estimates of the prevalence of intellectual disability or autism spectrum disorder (ASD) may vary depending on the methodology, geographical location, and sources of ascertainment. The National Disability Insurance Scheme (NDIS) in Australia was introduced progressively from 2016 to provide individualized funding for eligible people with a significant and permanent disability.

Methods

Its recent inclusion as a source of ascertainment in the population-based Intellectual Disability Exploring Answers (IDEA) database in Western Australia has allowed comparisons of the prevalence of intellectual disability and ASD before and after its introduction.

Results

Prevalence of intellectual disability in 2020 was 22.5 per 1,000 (/1,000) live births compared with previous estimates in 2010 of 17/1,000, and for ASD, the estimate was 20.7/1,000 in 2020 compared with 5.1 /1,000 in 2010. Whilst the prevalence of ASD in Aboriginal individuals was about two-thirds that of non-Aboriginals, there was an increased prevalence of ASD in Aboriginal children under 10 years compared with non-Aboriginal children.

Discussion

The concurrent relaxation of ASD diagnostic practice standards in Western Australia associated with the administration of access to the NDIS and the release of the National Guidelines empowering single diagnosticians to determine the appropriateness of engaging additional diagnosticians to form a multidisciplinary team on ASD diagnosis, appear to be important factors associated with the increase in ASD diagnoses both with and without intellectual disability.

Inclusion, acceptance, shame and isolation: Attitudes to autism in Aboriginal and Torres Strait Islander communities in Australia

LAY ABSTRACT

There has been almost no research done about autism in Aboriginal and Torres Strait Islander communities in Australia. This article is the first detailed report on attitudes to autism in these communities. Understanding attitudes to autism is important because they influence whether or not children are diagnosed, as well as the kinds of support autistic people are getting. Twelve families who lived in different parts of Australia were interviewed. They told us that there is a range of attitudes to autism in Aboriginal and Torres Strait Islander communities. These include negative ideas such as sometimes feeling shame associated with children's unusual behaviour, as well as feeling stigmatised and socially isolated. The negative attitudes reported may mean that some children are missing out on an autism diagnosis or being wrongly diagnosed with a different condition in these communities. They also included positive ideas such as the importance of looking after each other and of accepting autistic people and their differences. We can all learn from these positive attitudes. It will be interesting to know in future projects whether these accepting attitudes lead to better outcomes for autistic children and adults in these communities. This research helps us to understand how autism is thought about in different cultures and how attitudes impact diagnosis and support. It will also help people to plan supports that reflect what Aboriginal and Torres Strait Islander families actually want and need.
