Reconciling the seemingly irreconcilable: The WHO's ICF system integrates biological and psychosocial environmental determinants of autism and ADHD: The International Classification of Functioning (ICF) allows to model opposed biomedical and neurodiverse views of autism and ADHD within one framework.

Neurodevelopmental disorders (NDDs), such as autism and ADHD, are behaviorally defined adaptive functioning difficulties arising from variations, alterations and atypical maturation of the brain. While it is widely agreed that NDDs are complex conditions with their presentation and functional impact underpinned by diverse genetic and environmental factors, contemporary and polarizing debate has focused on the appropriateness of the biomedical as opposed to the neurodiverse paradigm in framing conceptions of these conditions. Despite being largely overlooked by both research and practice, the International Classification of Functioning Disability and Health (ICF) endorsed by the World Health Organization in 2001 views functioning dynamically, offering a framework for investigating, assessing and treating NDDs holistically. Exemplified by autism and ADHD, we argue that the ICF provides not only a multitude of opportunities in accounting for the environmental determinants in researching and clinically managing NDDs, but opportunities for harmonizing the seemingly irreconcilable biomedical and neurodiverse paradigms.

'We have so much to offer': Community members' perspectives on autism research.

LAY ABSTRACT: Autism research is changing. Autistic activists and researchers want Autistic people in the community to have more of a say about what is researched and how. But we haven't asked people in the community what they think. This study used the information obtained from 55 community members, including Autistic people, their families, and professionals working with Autistic people, from an existing study on their priorities for autism research. We re-looked at what was said to see if we could understand community members' views and experiences of autism research. People agreed strongly that research can play a powerful role in shaping good Autistic lives. They also felt that big changes were needed for research to do this. Some of these changes were that researchers should stop thinking about autism narrowly and in a negative way, where Autistic people are seen as the problem. Researchers need to think more about how to improve systems, experiences and how other people respond to Autistic people. They also want the autism community to be more involved in what is researched and how it is researched. The findings from our study here highlight the potential for research to be positive when Autistic people and their families are listened to, approached with understanding, and are respected and valued as individuals in the research process.

"In a State of Flow": A Qualitative Examination of Autistic Adults' Phenomenological Experiences of Task Immersion.

Background: There is considerable conceptual overlap between Autistic hyperfocus and flow, yet these phenomena have seldom been associated in the literature. Moreover, no studies have provided an in-depth empirical investigation of Autistic people's flow-like or hyperfocus experiences. In this study, we sought to address this gap by investigating Autistic people's phenomenological experiences of task immersion, and how their experiences relate to existing conceptualizations of flow, hyperfocus, and monotropism. Methods: To address this aim, we drew on data from a broader qualitative study, designed in partnership with Autistic community members, to understand Autistic people's experiences of Autistic inertia. For that broader study, Autistic and non-Autistic researchers conducted semi-structured interviews with 24 Autistic adults about their everyday experiences of starting and stopping tasks. During these interviews, participants repeatedly discussed their experiences of task immersion and the benefits and challenges associated with it. We analyzed these responses specifically, using reflexive thematic analysis, adopting a combination of deductive and inductive approaches within an essentialist framework. Results: Our participants' accounts closely matched conceptual understandings of flow, Autistic hyperfocus, and monotropism. Specifically, the analysis revealed the all-encompassing nature of task immersion experiences, and how it could be difficult to "find the balance" between the joy and other aspects of everyday life. Despite the drawbacks, participants were glad to be immersed because they felt they could be themselves, with no pretences. Conclusions: These results are important for reframing task immersion as a state of great potential value to Autistic people's lives, but one that may require additional support if it is to play its role in enabling Autistic people to flourish.

Why is this an important issue? Flow is a state of mind where a person becomes completely absorbed in what they are doing and does not notice anything around them. Autistic people's experiences of flow has not been studied enough, possibly because Autistic "voices" have not been taken seriously by autism researchers in the past. This means we know little about Autistic people's experiences of flow-like states. What was the purpose of this study? We wanted to know about Autistic people's experiences of flow and what effect these experiences had on their everyday lives. What did the researchers do? One Autistic and one non-autistic researcher spoke to 24 Autistic adults about their experiences of becoming fully engaged and focused on tasks. During the interview, we asked participants to tell us about moments when they felt so immersed in a task, or a thought, that they could not (or did not want to) stop. We also asked how not being able (or not wanting to) stop a task or a thought impacts their lives. What were the results of the study? Our Autistic participants' descriptions of their flow-like experiences seemed to be closely related to other concepts that are often talked about in the Autistic community, such as hyperfocus and monotropism. They spoke of how their flow-like experiences were all-encompassing and could bring much pleasure. But they also told us how flow could bring a great deal of struggle, as it could lead to exhaustion or neglect of other tasks (including personal care). Despite the challenges, participants enjoyed being in flow as it allowed them to be themselves. What do these findings add to what was already known? This study showed that Autistic flow (or "hyperfocus") can be "the most amazing feeling in the world." It also showed that being in flow can cause challenges. We need to work with Autistic community members to develop strategies to help Autistic people manage the negative effects on everyday life and physical health and well-being. What are potential weaknesses in the study? Most of our Autistic participants were women who were White, well-educated, and employed. Most also used traditional forms of communication. We do not know if our participants' flow-like experiences are similar to Autistic people who do not use traditional forms of communication, have an intellectual disability and come from different cultures. It will also be important to work with Autistic people and their allies to find new ways to investigate flow experiences in a diverse range of Autistic people. How will these findings help autistic adults now or in the future? These findings show how important it is to focus on things that can bring Autistic people joy. We need to know more about how increasing optimal flow experiences­at home, in schools, at work­could help Autistic people to thrive.

'I live in extremes': A qualitative investigation of Autistic adults' experiences of inertial rest and motion.

LAY ABSTRACT: 'Autistic inertia' is a term used by Autistic people to refer to difficulties with starting and stopping tasks. However, there has not been much research on Autistic inertia. The research that is available on Autistic inertia has mostly focused on the negative aspects of inertia, rather than on the possible benefits of needing to continue tasks. In this research, we wanted to understand more about Autistic people's experiences of inertia and to work out what things might influence these experiences. Autistic and non-Autistic researchers spoke in-depth to 24 Autistic adults. We identified four key ideas from people's responses. Autistic people spoke about their inertial 'difficulties moving from one state to another' and described how these challenges affected them 'every single day'. While they experienced inertia as 'the single most disabling part of being Autistic', people also described the positive aspects of inertia, including the joy they felt when completely immersed in a task. Our Autistic participants emphasised that inertial difficulties are experienced by everyone, the intensity of these task-switching difficulties might be especially challenging for Autistic people. Our findings also reveal how Autistic inertia can be seen both as a disabling and as an enabling condition.

"Peas in a pod": Oral History Reflections on Autistic Identity in Family and Community by Late-Diagnosed Adults.

In this paper, we report on a participatory oral history study documenting the lives of late-diagnosed autistic adults in Australia. We interviewed 26 autistic adults about their life history and the impact of late diagnosis. All were diagnosed after the age of 35, growing up in an era when autism was not well known. Using reflexive thematic analysis, we uncovered a rich body of reflections on shared Autistic identity and identified three major themes within that data set: 'conceptualising the Autistic family', 'creating Autistic community', and 'contesting Autistic identity'. Overall, the study provides insights into the active creation of shared Autistic identity and the importance of Autistic community to these late-diagnosed autistic adults.

'Somali parents feel like they're on the outer': Somali mothers' experiences of parent-teacher relationships for their autistic children.

LAY ABSTRACT: Good relationships between parents and schools can improve autistic children's school success. There are many reasons why families from different cultural backgrounds find it harder to develop good relationships with schools, such as language barriers, discrimination and unfamiliarity with education systems. We know little about what 'good relationships' look like for these families. Here, we worked with a team of autistic and non-autistic researchers as well as an Advisory Group of Somali parents to conduct interviews with 15 Somali mothers of kindergarten and school-age autistic children. We asked mothers about their experiences of their child's education, communication with teachers and what a good relationship with schools would look like. We also asked how they felt the Somali community understood autism. We looked for common things that mothers said. We found that mothers were very proud of their children. They had high expectations, particularly about what children could do by themselves. Mothers found it frustrating that teachers had low expectations, that schools were not good at communicating with them and that autism-specific skills and experience were uncommon in schools. They also reported racist attitudes towards their children. Mothers experienced stigma and lacked resources, but support was gained from their daughters and their religion. Mothers themselves were proactively increasing community awareness and knowledge about autism in the hope that they and their autistic children would be valued and better supported. Our work has implications for how teachers and schools can work together with Somali parents to forge better futures for autistic children.

The Intersection of Autism and Transgender and Nonbinary Identities: Community and Academic Dialogue on Research and Advocacy.

Many transgender people are autistic. Community expressions of the autism transgender intersection abound. Some commentators have questioned the proportional overrepresentation of autism among gender-diverse people, suggesting these individuals may not be truly autistic or truly transgender. However, increasing evidence challenges assertions that deny the authenticity of co-occurring autistic and transgender identities. Specifically, research by authors of this article indicates autistic transgender people show neurophenotypes generally consistent with cisgender autistic people and implicit gender phenotypes consistent with nonautistic transgender people. This article features a dialogue between eight leading experts in the field of intersectional autism and gender diversity, including clinicians, researchers, community advocates, and experts who are themselves autistic transgender. Key topics of discussion included: how research findings on autism and gender diversity inform respectful and supportive responses to autistic transgender people; the benefits and harms of increased societal attention toward the autism transgender intersection; and research and advocacy priorities. The expert panel concluded the following: (1) it is important to respect transgender autistic people's wellness and resilience, while also acknowledging the pathologization and stigmatization they face; (2) autistic gender-diverse people are experts of their own identity and should be involved in all aspects of research and clinical care; (3) research is needed to understand the disparities autistic transgender people face; (4) attempts to restrict autistic transgender people's access to gender care are unsupported by existing research; (5) adult gender care may benefit from incorporating universal design principles and neurodiversity-affirming strategies to reduce barriers to care and improve clinician-client communication in treatment delivery and the informed consent process; (6) cross-cultural and cross-societal research will improve best care practices in diverse contexts; (7) research and advocacy must be inclusive across ethnoracial identities, including in leadership and perspectives represented; and (8) a life span developmental framework is needed for adult research in this field.

"They Were Saying That I Was a Typical Chinese Mum" : Chinese Parents' Experiences of Parent-Teacher Partnerships for Their Autistic Children.

Effective parent-teacher partnerships improve outcomes for autistic students. Yet, we know little about what effective partnerships look like for parents of autistic children from different backgrounds. We conducted interviews with 17 Chinese parents of autistic children attending Australian kindergartens/schools to understand their experiences. Parents appreciated the acceptance, opportunities and supports they received in Australia. They had high expectations of children; expectations not often shared by educators. Parents were respectful of teachers' expertise and polite and undemanding in interactions. Nevertheless, parents were frustrated by inconsistent teaching quality and inadequate communication. Navigating systems was also challenging and parents faced discrimination from teachers and their community. Recommendations include fostering open home-school communication, proactively seeking parents' expertise about children and explicitly scaffolding parents' self-advocacy.

'It's really important to be collaborating': Experiences of participatory research for Chinese and Vietnamese parents of autistic children.

Background and aims: Participatory research involves academic partners working together with the community that is affected by research to make decisions about that research. Such approaches often result in research that is more respectful of, and responsive to, community preferences - and is vital in the context of autism research with culturally and linguistically diverse (CALD) communities. Whilst participatory approaches are becoming more commonplace within CALD autism research, no studies have explored the experiences of being involved in autism research from the perspectives of CALD community partners over the course of a study. This paper intended to address this gap by reporting on the experiences of CALD parents of autistic children who were community partners in a 1-year Australian research project exploring home-school partnerships for CALD parents of autistic children. We aimed to: (1) report on how parents' involvement in the research process shaped the home-school partnerships study over time and (2) understand their experiences of being community partners on the home-school partnerships project. Methods: Using key principles of participatory approaches, we established Chinese and Vietnamese parent advisory groups to contribute to a project exploring home-school partnerships for parents of autistic children from CALD backgrounds in Australia. Advisory groups included parents of autistic children from Chinese/Vietnamese backgrounds, as well as interpreters, professionals and researchers. We documented how parents' participation as community partners shaped the home-school partnerships study over the course of the project. We also elicited parents' own views and experiences of being community partners through informal, open-ended questions at the beginning and end of the study. Results: We found that parents' input fundamentally shaped the broader home-school partnership study, from meaningful, accurate translation of interview schedules through to making decisions regarding community-specific recommendations and dissemination plans. Parents themselves reported being keen to collaborate and to hear and share opinions for the purpose of the home-school partnership study - although they noted how emotionally difficult sharing their stories could be. While they initially had some concerns about combining being involved as a community partner with their existing responsibilities, ultimately, parents were surprised by the scope of the home-school partnership study and their level of involvement as community partners. Through hearing others' stories and sharing their own in advisory group meetings, parents reported ancillary benefits of their involvement, including increased self-advocacy and well-being. Conclusions: These findings show how research that is conducted in partnership with diverse members of the autism community has the capacity to improve the quality of the research and benefit community partners. Implications: This study clearly documents the benefits and potential challenges of participatory approaches with CALD communities. These findings emphasise to researchers and funders the importance of including extra time and money within budgets in order to produce meaningful research that is respectful and responsive to communities.

The Gender-Diversity and Autism Questionnaire: A Community-Developed Clinical, Research, and Self-Advocacy Tool for Autistic Transgender and Gender-Diverse Young Adults.

Background: Autistic transgender people face unique risks in society, including inequities in accessing needed care and related mental health disparities. Given the need for specific and culturally responsive accommodations/supports, the characterization of key experiences, challenges, needs, and resilience factors within this population is imperative. This study developed a structured self-report tool for autistic transgender young adults to communicate their experiences and needs in a report format attuned to common autistic thinking and communication styles. Methods: This cross-nation project developed and refined the Gender-Diversity and Autism Questionnaire through an iterative community-based approach using Delphi panel methodology. This proof-of-principle project defined "expertise" broadly, employing a multi-input expert search approach to balance academic-, community-, and lived experience-based expertise. Results: The expert collaborators (N = 24 respondents) completed a two-round Delphi study, which developed 85 mostly closed-ended items based on 90% consensus. Final item content falls within six topic areas: the experience of identities; the impact of experienced or anticipated discrimination, bias, and violence toward autistic people and transgender people; tasks and experiences of everyday life; gender diversity- or autism-related care needs and history; the experience of others doubting an individual's gender identity and/or autism; and the experience of community and connectedness. The majority of retained items relate to tasks and experiences of everyday life or the impact of experienced or anticipated discrimination, bias, and violence. Conclusions: This study employed a multipronged multimodal search approach to maximize equity in representation of the expert measure development team. The resulting instrument, designed for clinical, research, and self-advocacy applications, has parallel Dutch and English versions and is available for immediate use. Future cross-cultural research with this instrument could help identify contextual risk and resilience factors to better understand and address inequities faced by this large intersectional population.

Why is this an important issue?: Transgender and gender-diverse are words used to describe people whose gender varies from their assigned sex at birth. Many autistic people identify as being transgender/gender-diverse. Autistic gender-diverse/transgender young adults often describe difficulties getting the care they need, which can increase their chances of experiencing stress and mental health challenges. This study created a self-report questionnaire for autistic transgender/gender-diverse young adults to share about their health care, support needs, and broader experiences. What were the results of the study?: A diverse group of experts in the autism and gender diversity co-occurrence, including autistic transgender people, worked together to develop the questionnaire. The researchers found experts by searching the internet and talking to people in the community and research field. The questionnaire is called the Gender-Diversity and Autism Questionnaire and has 85 questions that are grouped into 6 different areas: the experience of identities; the impact of experienced or anticipated discrimination, bias, and violence toward autistic people and transgender people; tasks and experiences of everyday life; gender diversity- or autism-related care needs and history; the experience of others doubting an individual's gender identity and/or autism; and the experience of community and connectedness. The questionnaire has English and Dutch versions so it can be used for research in different countries. What do the authors recommend for future research on this topic?: Researchers are currently using the new questionnaire to compare the experiences and needs of autistic transgender young adults in the Netherlands and the United States. The results may help explain why some outcomes are different between autistic transgender young people in the two countries and how culture and society play a role. How will these findings help autistic adults now or in the future?: We created the questionnaire to be used in different settings, including clinics and in research. The questionnaire gives autistic transgender young adults a structured way to communicate their experiences, needs, challenges, and areas of strength. The answers that an autistic transgender young adult gives on the questionnaire could help other people understand the clinical and community supports that the young adult wants and needs. Future studies may use the questionnaire to understand obstacles that autistic transgender young adults may face.

Perspective: Presuming Autistic Communication Competence and Reframing Facilitated Communication.

Debate surrounding the validity of the method of supported typing known as facilitated communication (FC) has been continuous since its inception in the 1990s. Views are polarized on whether FC can be considered an authenticated method for use by people with complex communication needs (CCN) or significant challenges in speech, language, and communication. This perspective article presents an analysis of the research arguing for-and against-the use of FC, combined with the lived experience knowledge of autistic adults who utilize FC, to rehabilitate its current standing as discredited and unevidenced. By considering extant qualitative and quantitative studies, as well as personal accounts of the use of this particular Augmentative and Alternative Communication (AAC) method, the authors argue that the current dismissal of FC is rooted in ableist and outdated approaches. FC research should be reconsidered and reconducted using current best practice autism research approaches, including coproduction and a presumption of autistic communication competence, to assess its validity as a potential AAC method for autistic individuals.

A capabilities approach to understanding and supporting autistic adulthood.

There is little comprehensive research into autistic adulthood, and even less into the services and supports that are most likely to foster flourishing adult autistic lives. This limited research is partly because autism is largely conceived as a condition of childhood, but this focus of research has also resulted from the orthodox scientific approach to autism, which conceptualizes autistic experience almost entirely as a series of biologically derived functional deficits. Approaching autism in this way severely limits what is known about this neurodevelopmental difference, how research is conducted and the services and supports available. In this Review, we adopt an alternative research strategy: we apply Martha Nussbaum's capabilities approach, which focuses on ten core elements of a thriving human life, to research on autistic adulthood. In doing so, we identify areas where autistic adults thrive and where they often struggle, and highlight issues to which researchers, clinicians and policymakers should respond. The resulting picture is far more complex than conventional accounts of autism imply. It also reveals the importance of engaging autistic adults directly in the research process to make progress towards genuinely knowing autism and supporting flourishing autistic lives.

"I Knew She'd Get It, and Get Me": Participants' Perspectives of a Participatory Autism Research Project.

Introduction: Autistic advocates and their supporters have long argued that conventional research practices provide too few opportunities for genuine engagement with autistic people, contributing to social disenfranchisement among autistic people. We recently described one attempt to develop and implement a participatory study in which a team of autistic and nonautistic researchers worked together to gather life histories from late-diagnosed autistic people. In the current study, we sought to understand the impact of this participatory approach on the participants themselves. Methods: We spoke to 25 Australian late-diagnosed autistic adults (aged 45-72 years), who had been interviewed by an autistic researcher using an oral history approach. We asked them about their experience of being involved in that project and the research process more broadly. We thematically analyzed participants' interviews. Results: Participants responded overwhelmingly positively to the opportunity to tell their life history, considering it illuminating and empowering. While recounting their life history was often described as "exhausting" and "draining," participants also reported feeling "supported all the way" and agreed "it was made easier because I had an autistic researcher interviewing me." One participant went so far as to say that they "probably would have dropped out [of the project] if it was run by people who weren't autistic." Conclusions: These findings demonstrate that the benefits of coproduction to researchers and community partners extend to study participants and to the quality of the research itself. Involving autistic partners in the research process, especially in its implementation, can play a crucial role in enhancing autism research.

Why is this an important issue?: Autistic people are often left out of decisions that affect them, including in research. We wanted to change that. We, a group of autistic and nonautistic researchers, worked together to come up with a research project. In that project, we wanted to know more about autistic people who were diagnosed late in their lives. What was the purpose of this study?: We wanted to know about their experiences of taking part in the research. We also wanted to understand what it was like for our study participants to tell their life story to another autistic person. What did we do?: We spoke to 25 autistic people about their experiences of telling their life history. We asked questions like, "Can you tell me a bit about why you wanted to share your life history?" and "What was your overall experience of taking part in this research project?" We interviewed participants for about 25 minutes. What were the results of the study?: We found that participants felt good about taking part in this project. They felt supported and were pleased that the project was being run by autistic people. They also told us that telling their story was often painful. However, it was made easier because they had an autistic researcher interviewing them. They also felt that they could share more with this person than with someone who was not an autistic person. What do these findings add to what was already known?: This study shows that research that is done together by autistic and nonautistic researchers has a positive effect on participants. What are the potential weaknesses in the study?: Most of our participants were well educated, White, and were in some form of work. We do not know if participants' positive experiences would also happen with other autistic people, including those from different cultural groups. This study was also unusual because it allowed participants to tell their own stories in their own way. That might have made participants more positive about it. How will these findings help autistic adults now or in the future?: These findings show how important it is to include autistic people in research. It makes a real difference to the participants and to the quality of the research.

'A way to be me': Autobiographical reflections of autistic adults diagnosed in mid-to-late adulthood.

LAY ABSTRACT: Using oral history methods, we interviewed and recorded 26 autistic adults in Australia about their life history. We wanted to better understand interviewees' self-reflections about their lives. The interviewers were autistic researchers and the interviews were analysed by autistic and non-autistic researchers. All of the adults we interviewed were born before 1975 and formally identified as autistic after age 35 years. This group of people is sometimes referred to as 'late-diagnosed autistic adults'. In general, there is not much research done about autistic adults and even less is known about those diagnosed late in life. In this article, we explore what these adults said about their sense of self and how that changed over time. These autistic adults told us about many negative experiences, including trauma, which had shaped how they think about themselves. For most, autism diagnosis had a very positive impact on their sense of self, allowing them to understand more about their own past and to feel good about their autistic identity. Previously some researchers have said that autistic people have a limited or impaired sense of self. Instead, our results show some autistic people can actually reflect deeply on their lives and their changing sense of self-identity over time.

Language, interests and autism: A tribute to Dr. Dinah Murray (1946-2021), an autism pioneer.

So much has changed in our understanding of how autism impacts our lives. We still have a long way to go, however, until it becomes the norm that the principle of 'nothing about me without me' is upheld throughout autism research and autism practice. Autistic researchers and practitioners will play a central role in delivering this vision. Currently, the autistic community is mourning the passing of one such person, a true pioneer, Dr. Dinah Murray. It is fitting that we pay a tribute to her achievements and contributions, for these have enriched our lives and over-laid the autism landscape with understanding, acceptance, action and advocacy.I am not proposing that we change those opening paragraphs, just that we duplicate and adjust the text in the abstract as well. I think that reading this on the journal page would help people decide if they want to read the full letter, by giving them a bit more of a taste of the rest of the piece. I don't think it matters that the text will be repeated in the main article - this is a common practice for things like letters to the editor and commentaries.

"Just Ask Me": The Importance of Respectful Relationships Within Schools.

An inclusive approach to education requires schools and educators to address the support needs and individual predispositions of all students. Our research highlights the crucial importance of effective and respectful communication with autistic students to facilitate their successful participation in schools. This paper explores the experiences of 24 autistic individuals aged 16-67 years, through synchronous semi-structured interviews and written responses. The research team comprised both autistic and allistic (non-autistic) researchers, who worked together to design the overall project, collect interview data, and analyse the data. Relationships were frequently discussed by participants and the importance of positive relationships was positioned as key to successful participation within educational contexts. Particularly damaging were assumptions made by teachers concerning individual ability based on labels given. Participants recalled ongoing challenges with resisting stereotypes and managing stigma, while trying to craft a positive autistic identity and advocate for rightful supports for their education. At the core of these negotiations were positive relationships, and teachers who asked participants what their needs were, and then listened and proactively responded to their answers. Recommendations for more positive schooling engagements with autistic young people are provided.

Strategies for Research, Practice, and Policy for Autism in Later Life: A Report from a Think Tank on Aging and Autism.

Over the past decade, there has been a growing interest in adults on the autistic spectrum, and more recently, the challenges related to aging in this population. A two-day Think Tank meeting, focused on aging in autism, was convened amongst international leaders in the field of autism research and practice. This meeting included a series of presentations addressing the current status of aging research, followed by discussions regarding priorities going forward. Attendees shared their thoughts and concerns regarding community services, government policies, societal perspectives and physical and mental health. The goal of these discussions was to consider systematic approaches aimed at providing meaningful supports that can ensure a quality of life for seniors on the autism spectrum.

Documenting the untold histories of late-diagnosed autistic adults: a qualitative study protocol using oral history methodology.

INTRODUCTION: Receiving a diagnosis of autism in adulthood is increasingly common for a subset of individuals who were either misdiagnosed in childhood or missed out on a diagnosis altogether. This qualitative study, coproduced with autistic people, invites late-diagnosed autistic adults to share their life histories to (1) understand better the consequences of living without a diagnosis, (2) elucidate what precipitates an autism diagnosis in mid-to-late adulthood and (3) identify the perceived impact of receiving that diagnosis. METHODS AND ANALYSIS: Oral histories have been a successful way to uncover overlooked and marginalised voices. We therefore adopt qualitative, oral history methodology in this study to understand these adults' experiences, especially of living in an era when autism was not well known. We will recruit 24 participants who will (1) have been born before 1975, (2) have received a clinical, autism diagnosis after the age of 35, (3) be English-speaking and (4) have spent most of their childhood and adulthood living in Australia. Participants will take part in four sessions, including the main, qualitative, oral history interview, through a range of possible formats to facilitate inclusion. The interview data will be analysed using reflexive thematic analysis. ETHICS AND DISSEMINATION: The protocol has received institutional research ethics approval from Macquarie University's Human Research Ethics Committee (Ref.: 52019556310562). This study will yield understanding of the life experiences of autistic adults, especially middle-aged and older Australians, should inform more effective diagnostic practices and provide insight into the key factors that might promote resilience and enhance quality of life in autistic people. The findings will be disseminated to academic and clinical audiences through journal articles and conference presentations and to the autistic and autism communities through accessible reports. The interviews will also be prepared for digital archiving, which will enable ongoing access for future generations and communities.
