Understanding the post-diagnostic support priorities of autistic adults in the United Kingdom: A co-produced modified Delphi study.

Autistic adults in the United Kingdom report that support for themselves and their peers is not suitable for their needs. There has been an increase in adults receiving an autism diagnosis, which many have reported as having a positive impact on their lives. However, the lack of support and understanding after diagnosis, combined with long wait times for an assessment to obtain a diagnosis and to access follow-on support, is having a negative impact on people's lives. This study took place to find out what support autistic people need and want after receiving their diagnosis. It was co-designed with a group of 10 autistic adults which means that the researchers and group members collaboratively designed the research. For the study, 43 autistic adults, diagnosed aged 18 or older, completed three questionnaires. A fourth questionnaire followed that was completed by 139 autistic people who received their diagnosis in adulthood. These questionnaires aimed to help people identify their own priorities when it came to the support they would have liked to receive after being given their autism diagnosis. Participants ranked , , , and as their top priorities. This demonstrates that local support is highly valued by autistic adults, as are well-trained professionals who offer a range of contact options, support to process a late-in-life autism diagnosis and help to develop and implement support plans.
