Autistic adults’ views on the design and processes within randomised controlled trials: The APRiCoT study

Authors

Abstract

The purpose of this study is to explore the views of autistic adults on randomised controlled trials, specifically on processes such as randomisation and blinding, to understand the barriers and facilitators for recruiting autistic people to randomised controlled trials involving medications. We conducted one-to-one interviews with 49 autistic adults. Interviews were audio-recorded and analysed thematically. The participants found randomised controlled trial processes acceptable and linked positive attitudes towards randomised controlled trial participation to autistic peoples’ heightened sense of fairness and preference for evidence-driven knowledge. However, randomised controlled trial designs may be incompatible with a (1) preference for a controlled predictable world, (2) perceived vulnerability at physical and mental health levels and (3) history of misunderstanding and exclusion, crucially from healthcare professionals. Suggestions that emerged from our findings include efforts to co-produce research to nurture trust and adapting communication practices to improve access to trials. Autistic people are a highly motivated group to work with research teams to mitigate barriers to randomised controlled trial participation. We explored what psychosocial determinants play a role in the acceptability of randomised controlled trials to test interventions to improve quality of life and mental health in autistic adults. The study provides useful information that may help the design and conduct of more accessible trials with and for the autistic community. Lay abstract Large randomised controlled trials are used to test healthcare treatments. Yet there are no large randomised controlled trials on effective treatments for common mental health issues affecting autistic adults. The purpose of this study was to learn what autistic adults think about randomised controlled trials in preparation for a randomised controlled trial testing a medication for anxiety. This means we wanted to know their opinions about the way randomised controlled trials are done, such as how people are chosen to be in the study and how the study is carried out. We did this by talking to 49 autistic adults individually and asking them questions. We found that most of the people we talked to were okay with the way randomised controlled trials are done. They thought it was fair and they liked that it was based on evidence. However, some autistic people might find it hard to take part in randomised controlled trials. Some people did not like the uncertainty of not knowing what treatment they would receive in a randomised controlled trial. Others felt too vulnerable and may have had bad experiences with healthcare in the past. We found that it is important to involve autistic people early on and at every stage when designing a clinical trial. Care about how clear and precise the study communication is will build trust and improve access to research. Our study indicates that it is possible to conduct large randomised controlled trials with and for autistic people. This can ultimately contribute to the improvement of healthcare outcomes for this population.
