Position Statement – Applied Behaviour Analysis (ABA)

ABA is used in various ways with different groups including autistic children to intervene in the developmental trajectory of autism and to address issues related to learning and behaviour. Its use with autistic people was first introduced when the narrative focused on the perceived deficits of autism, with the aim of eliminating what were seen as deviant or abnormal behaviours and replacing these with what were perceived as normal. This has involved the use of punishments, including deprivation of food, restriction of freedom, and aversive procedures including inflicting painful electric shocks.

The more extreme aversive practices have largely been discontinued, and a change in narrative concerning an analysis of the meaning of behaviour has been introduced. However, there remain mixed opinions on the efficacy of the intervention and there are continued concerns around the ethics, restrictive practices, and potential for harm.

We believe the weight of evidence in support of harm has increased over time, including the direct lived experience of ABA reported by autistic people and the evidence provided by informed professionals. These harms extend to deprivation of liberty and abuse of human rights, personal trauma and poor mental health, and the adverse impact on the acceptance of autism as a valid identity.
It is our view that the evidence in support of harm and unethical application and abuse outweighs that of any perceived or reported benefit. For this reason, AT-Autism does not support the use of ABA or related behavioural interventions in autism.

We encourage the development of evidence-supported approaches that respect human rights and reflect present day attitudes and narratives. These promote an acceptance of autism, and recognise the realities faced by autistic children and adults in all areas of their lives. Such approaches will be ethical, socially inclusive and focus on personal wellbeing and quality of life. They will recognise the strengths and the real challenges faced by autistic people.
These approaches are increasingly autistic-led or are co-developed and co-delivered with autistic people, a course we wholeheartedly commend and support.
