Living with autism without knowing: receiving a diagnosis in later life

Autistic Traits, Communicative Efficiency, and Social Biases Shape Language Learning in Autistic and Allistic Learners

There is ample evidence that individual-level cognitive mechanisms active during language learning and use can contribute to the evolution of language. For example, experimental work suggests that learners will reduce case marking in a language where grammatical roles are reliably indicated by fixed word order, a correlation found robustly in the languages of the world. However, such research often assumes homogeneity among language learners and users, or at least does not dig into individual differences in behavior. Yet, it is increasingly clear that language users vary in a large number of ways: in culture, in demographics, and-critically for present purposes-in terms of cognitive diversity. Here, we explore how neurodiversity impacts behavior in an experimental task similar to the one summarized above, and how this behavior interacts with social pressures. We find both similarities and differences between autistic and nonautistic English-speaking individuals, suggesting that neurodiversity can impact language change in the lab. This, in turn, highlights the potential for future research on the role of neurodivergent populations in language evolution more generally.

A qualitative interview study on quality of life and ageing experiences of autistic adults

Quality of life across the lifespan has been established as a key research priority by the autism community. Still relatively little is known about the quality of life and ageing experiences of older autistic adults. Most studies to date have used generic measures of quality of life which may not accurately capture the experiences of autistic people. The aim of this qualitative study was to understand how autistic adults experience and define quality of life as they age. We conducted semi-structured interviews with 16 autistic adults aged 40+ from the UK and Luxembourg. Using reflexive thematic analysis, we identified five themes that contribute to quality of life: (1) Diagnosis is pivotal, (2) Connection with others, (3) Autonomy over space and time, (4) 'Paperwork of life', (5) Vulnerability. This study identifies autism-specific aspects of quality of life and highlights ways in which ageing and autism intersect and impact quality of life.

Groups and Subgroups in Autism Spectrum Disorder (ASD) Considering an Advanced Integrative Model (AIM)

BACKGROUND

Autism spectrum disorder (ASD) is related to social communication difficulties, repetitive behaviors, and highly restricted interests beginning early in life. Currently, ASD is more diagnosed than in the past, and new models are needed. The Advanced Integrative Model (AIM) is a new model in which genes and concomitant medical problems to diagnosis (CMPD) and the impact of their rigorous and adequate treatment are considered.

METHODS

The role of a dynamic encephalopathy from which the individual response, susceptibilities in the brain and outside the brain, gut barrier and brain-blood-barrier permeabilities, and the plastic nature of the brain is proposed as a tool for diagnosis. The concomitant medical problems (CMP) are those at and outside the brain. The individual response to treatments of CMP is analyzed.

RESULTS

The AIM allows for classification into 3 main groups and 24 subgroups.

CONCLUSIONS

The groups and subgroups in ASD are obtained taking into account CMPD treatments and individual response.

Post-diagnostic support for adults diagnosed with autism in adulthood in the UK: A systematic review with narrative synthesis

LAY ABSTRACT

More adults than ever before are seeking an autism diagnosis in adulthood. While receiving a diagnosis may be beneficial, many autistic people struggle to navigate their new diagnosis, and require support. This study conducted a systematic review of previous research on the support available after diagnosis (post-diagnostic support) for autistic adults without intellectual disability who were diagnosed in adulthood in the UK. A systematic review is a pre-planned method of searching for all relevant studies, before combining these to answer a larger question. The study aimed to investigate the availability of such support and its effectiveness, and to explore autistic adults' experiences of accessing support. We also used publicly available information to create a map of the post-diagnostic support services currently available across the UK. A systematic search of seven databases was conducted, to identify UK-based studies published after 2012. Nineteen studies were eligible to be included in the study. Although some form of post-diagnostic support is available across most areas in the UK, this mostly consists of providing information and 'signposting' the person to other services. These options may not meet the needs of autistic people, who want services such as psychoeducation (therapy whereby an individual receives education about their diagnosis to improve understanding and self-management), and peer support. Findings highlight the need for adequate support to alleviate the post-diagnostic challenges autistic adults face. The study could not evaluate the effectiveness of support options in the UK due to a lack of information about this in published research. Research shows that autistic adults would like low-level support services, psychoeducation, and peer support, and may also prefer autistic-led support. Further research is required to develop and evaluate post-diagnostic support programmes which include these elements.

Understanding autism and its treatment: The child's perspective

INTRODUCTION

While parents' and professionals' perceptions regarding children with autism spectrum disorder (ASD) have been studied extensively, limited data regarding the perspectives of children with ASD on their needs and the challenges they face are available. The study aimed to examine how children with ASD understand their condition and the aims of the interventions they undergo.

METHODS

Nineteen children and adolescents (ages 5.7-14.2 years) formally diagnosed with ASD, with borderline to high intelligence (range 70-140), and able to converse verbally were interviewed in person at a child development clinic. A qualitative approach was used to capture children's perceptions of their strengths and challenges and their understanding of a novel ASD treatment. The interview included direct and projective open-ended questions on each topic. Interpretive content analysis was used to evaluate the children's answers. Medical data were extracted from medical records. The children's parents completed questionnaires on their children's disability levels, awareness of ASD diagnosis, and sociodemographic details.

FINDINGS

Children spoke of their embodied sensations and feelings and discussed "normality" vs. "disability." They varied in their awareness of their diagnosis/symptoms, and only one boy named his diagnosis and described its consequences in detail. Most children lacked an understanding of the educational and therapeutic aspects of the goals set for them.

DISCUSSION AND CONCLUSIONS

Children with ASD are aware of their unique emotional and behavioral challenges. Nevertheless, they are frequently excluded from the process of patient information provision and lack an understanding of the goals of interventions. Findings suggest the need to explore developmentally and emotionally adaptive ways to involve children with ASD in discussions of their condition and possible interventions.

First things first: An exploration of the effects of psychoeducation for older autistic adults

LAY ABSTRACT

After receiving an autism diagnosis, psychoeducation (i.e. information regarding autism) is a first intervention. We adjusted a psychoeducation program that was originally developed by the Dutch Association for Autism for older adults to enhance its feasibility and efficacy in later life. We expected that participants would report an increase in knowledge and acceptance of the diagnosis and that people close to them would also observe this. Indeed, we found this and participants and those close to them agreed on this. Furthermore, we found some evidence that older autistic adults were better at coping with their autism. We found no positive intervention effects on psychological distress. The feedback of participants and informants about the psychoeducation program was largely positive. In future research, we advise using larger group samples and larger time scales and we also advise to further adjust the program to the needs and requirements of older adults, and to help older autistic adults to construct a new narrative of themselves, and the life they have lived, in the light of the recent autism diagnosis.

Being a Woman Is 100% Significant to My Experiences of Attention Deficit Hyperactivity Disorder and Autism: Exploring the Gendered Implications of an Adulthood Combined Autism and Attention Deficit Hyperactivity Disorder Diagnosis

This article provides original insight into women's experiences of adulthood diagnoses of attention deficit hyperactivity disorder (ADHD) and autism. Research exploring experiences of adulthood diagnoses of these conditions is emerging. Yet, there is no research about the gendered experiences of an adulthood combined ADHD and autism (AuDHD) diagnosis. This article addresses this gap through interpretative phenomenological analysis of email interviews with six late-diagnosed AuDHD women revealing the complex interplay between late diagnosis, being a woman, and combined diagnoses of ADHD and autism. It underscores how gender norms and stereotypes contribute to the oversight and dismissal of women's neurodivergence. Interpretative phenomenological analysis reveals the inextricability of femininity and neurotypicality, the gendered burden, discomfort, and adverse consequences of masking, along with the adverse outcomes of insufficient masking. Being an undiagnosed AuDHD woman is a confusing and traumatising experience with profound and enduring repercussions. The impact of female hormones exacerbated participants' struggles with (peri)menopause often being a catalyst for seeking diagnosis after decades of trauma. The epistemic injustice of not knowing they were neurodivergent compounded this trauma. Diagnosis enabled participants to overcome epistemic injustice and moved them into a feminist standpoint from which they challenge gendered inequalities relating to neurodiversity. This article aims to increase understanding and representation of late-diagnosed AuDHD women's lived experiences. The findings advocate for trauma-informed pre- and post-diagnosis support which addresses the gendered dimension of women's experiences of being missed and dismissed as neurodivergent. There needs to be better clinical and public understanding of how AuDHD presents in women to prevent epistemic injustice.

The emerging role of extracellular vesicles in the diagnosis and treatment of autism spectrum disorders

Autism spectrum disorders (ASD) are neurodevelopmental conditions characterized by restricted, repetitive behavioral patterns and deficits in social interactions. The prevalence of ASD has continued to rise in recent years. However, the etiology and pathophysiology of ASD remain largely unknown. Currently, the diagnosis of ASD relies on behavior measures, and there is a lack of reliable and objective biomarkers. In addition, there are still no effective pharmacologic therapies for the core symptoms of ASD. Extracellular vesicles (EVs) are lipid bilayer nanovesicles secreted by almost all types of cells. EVs play a vital role in cell-cell communications and are known to bear various biological functions. Emerging evidence demonstrated that EVs are involved in many physiological and pathological processes throughout the body and the content in EVs can reflect the status of the originating cells. EVs have demonstrated the potential of broad applications for the diagnosis and treatment of various brain diseases, suggesting that EVs may have also played a role in the pathological process of ASD. Besides, EVs can be utilized as therapeutic agents for their endogenous substances and biological functions. Additionally, EVs can serve as drug delivery tools as nano-sized vesicles with inherent targeting ability. Here, we discuss the potential of EVs to be considered as promising diagnostic biomarkers and their potential therapeutic applications for ASD.

Do autistic adults spontaneously reason about belief? A detailed exploration of alternative explanations

Southgate et al.'s (Southgate 2007 Psychol. Sci. 18, 587-92 (doi:10.1111/j.1467-9280.2007.01944.x)) anticipatory-looking paradigm has presented exciting yet inconclusive evidence surrounding spontaneous mentalizing in autism. The present study aimed to develop this paradigm to address alternative explanations for the lack of predictive eye movements on false-belief tasks by autistic adults. This was achieved through implementing a multi-trial design with matched true-belief conditions, and both high and low inhibitory demand false-belief conditions. We also sought to inspect if any group differences were related to group-specific patterns of attention on key events. Autistic adults were compared with non-autistic adults on this adapted implicit mentalizing task and an established explicit task. The two groups performed equally well in the explicit task; however, autistic adults did not show anticipatory-looking behaviour in the false-belief trials of the implicit task. Critically, both groups showed the same attentional distribution in the implicit task prior to action prediction, indicating that autistic adults process information from social cues in the same way as non-autistic adults, but this information is not then used to update mental representations. Our findings further document that many autistic people struggle to spontaneously mentalize others' beliefs, and this non-verbal paradigm holds promise for use with a wide range of ages and abilities.

Barriers to healthcare and a 'triple empathy problem' may lead to adverse outcomes for autistic adults: A qualitative study

LAY ABSTRACT

Autistic people live with more mental and physical health conditions and, on average, die younger than non-autistic people. Despite widespread commitments to tackling these issues, autistic people still report various barriers to accessing healthcare. This article aims to explore the area in depth, from the perspective of autistic people. This research benefits from being led by autistic people, for autistic people - all of the researchers are autistic, and most of us are also medical doctors. Data, in the form of written comments and stories, were collected as part of a large survey. Here, we explored these for common themes and possible deeper meaning within the experiences. People who took part reported a variety of barriers. Here, our article gives voice to their stories, in their own words. Themes included: early barriers; communication mismatch; doubt - in oneself and from doctors; helplessness and fear; and healthcare avoidance and adverse health outcomes. Our findings allowed us to create a model that aimed to understand and explain the reported barriers in the context of the previously known consequences. We also built on wider autism theories to explain our findings in more depth.

The adult experience of being diagnosed with autism spectrum disorder: A qualitative meta-synthesis

LAY ABSTRACT

There is little research looking at the experience of individuals diagnosed with autism spectrum disorder as adults. Adults diagnosed with autism spectrum disorder face different challenges than children, and more research is needed to better understand those challenges. For this review, autistic and non-autistic researchers looked at research on the experience of receiving a diagnosis of autism spectrum disorder as an adult. We looked for themes in people's experience leading up to diagnosis, going through the diagnostic process, and living their life after diagnosis. We analyzed 24 studies and found three overarching themes that captured thirty-two themes describing the experience of diagnosis. The three overarching themes expressed issues with identity and relationships before and after the diagnosis and identified that the diagnosis of autism spectrum disorder in adulthood impacted people's adaptation to and assimilation (i.e. the making sense of and internalizing the diagnosis) of autism spectrum disorder. While the diagnostic process itself was confusing and disappointing for many, it often led to a sense of relief and clarity regarding past experiences and had effects on identity and self-esteem. It created opportunities to connect with other autistic individuals and to access services, though appropriate supports were widely lacking. Recommendations are made that the impact of the diagnosis on people's identity and choices about telling others about their diagnosis, and whether and how people want to make adaptations, should be discussed and thought through in the process of diagnosis.

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

LAY ABSTRACT

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 access to support where they live, training of professionals, support to process the impact of a late diagnosis, use of their preferred mode of contact and a personalised support plan 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.

"Survival classes for a neurotypical world": What French autistic adults want and need after receiving an autism diagnosis

LAY ABSTRACT

Adults receiving an autism diagnosis might not react the same depending on their countries or cultures. We also know that autistic people are rarely asked what they think would be best for them following this diagnosis. In this study, we asked 12 French autistic adults about their experiences of receiving an autism diagnosis as well as what they thought might be useful afterwards. Overall, we found that some experiences were similar to experiences related by English or American participants, but some were specific to the French culture, suggesting that such research should expand into new territories and cultures, especially non-European ones. Our participants also had quite a few ideas as to what would be useful for people in the same situation. Some of the suggestions can be put into action by peers and professionals alike, while others are wishes relating to how our participants would like society to behave toward them and people like them, for example. This article allows for a better comprehension of how cultural differences can impact the experience of receiving an autism diagnosis as an adult and provides some insight into what these adults want and desire following such a diagnosis.

Loss-of-function variant in spermidine/spermine N1-acetyl transferase like 1 (SATL1) gene as an underlying cause of autism spectrum disorder

Autism spectrum disorder (ASD) is a complicated, lifelong neurodevelopmental disorder affecting verbal and non-verbal communication and social interactions. ASD signs and symptoms appear early in development before the age of 3 years. It is unlikely for a person to acquire autism after a period of normal development. However, we encountered an 8-year-old child who developed ASD later in life although his developmental milestones were normal at the beginning of life. Sequencing the complete coding part of the genome identified a hemizygous nonsense mutation (NM_001367857.2):c.1803C>G; (p.Tyr601Ter) in the gene (SATL1) encoding spermidine/spermine N1-acetyl transferase like 1. Screening an ASD cohort of 28 isolated patients for the SATL1 gene identified another patient with the same variant. Although SATL1 mutations have not been associated with any human diseases, our data suggests that a mutation in SATL1 is the underlying cause of ASD in our cases. In mammals, mutations in spermine synthase (SMS), an enzyme needed for the synthesis of spermidine polyamine, have been reported in a syndromic form of the X-linked mental retardation. Moreover, SATL1 gene expression studies showed a relatively higher expression of SATL1 transcripts in ASD related parts of the brain including the cerebellum, amygdala and frontal cortex. Additionally, spermidine has been characterized in the context of learning and memory and supplementations with spermidine increase neuroprotective effects and decrease age-induced memory impairment. Furthermore, spermidine biosynthesis is required for spontaneous axonal regeneration and prevents α-synuclein neurotoxicity in invertebrate models. Thus, we report, for the first time, that a mutation in the SATL1 gene could be a contributing factor in the development of autistic symptoms in our patients.

Maternal Autistic Traits and Adverse Birth Outcomes

Importance

Women with a high level of autistic traits in the general population may experience larger health disparities during pregnancy, particularly women diagnosed with autism spectrum disorder (ASD), which in turn may be associated with increased risk of adverse birth outcomes.

Objective

To investigate the association between maternal autistic traits and the risk of adverse birth outcomes in the general population.

Design, Setting, and Participants

This cohort study included mothers of singletons from a nationwide, multicenter prospective birth cohort, the Japan Environmental Children's Study. Expecting mothers were recruited between January 2011 and March 2014. Data were analyzed between June 2021 and November 2023.

Exposures

Autistic traits were self-reported during the second and third trimesters using the short form of the Autism-Spectrum Quotient Japanese version (AQ-J10) (score range, 0-10; clinical range, ≥7).

Main Outcomes and Measures

Data on preterm birth (<37 weeks' gestation) and neonates born small for gestational age (SGA) were transcribed from medical records. Additional analysis of gestational age groups (very preterm birth, <32 weeks' gestation; moderate-to-late preterm birth, 32-36 weeks' gestation) was also performed.

Results

Among 87 687 women (mean [SD] age, 31.2 [5.0] years) included in the study, 2350 (2.7%) had AQ-J10 scores within the clinical range yet only 18 (0.02%) were diagnosed with ASD. A higher AQ-J10 score was associated with an increased risk of all birth outcomes, including preterm births (relative risk [RR] per 1-SD increase, 1.06; 95% CI, 1.03-1.09), moderate-to-late preterm births (RR per 1-SD increase, 1.05; 95% CI, 1.01-1.08), very preterm births (RR per 1-SD increase, 1.16; 95% CI, 1.06-1.26), and child born SGA (RR per 1-SD increase, 1.04; 95% CI, 1.01-1.06) after adjusting for maternal and pregnancy-related factors. The risks of all outcomes increased with higher AQ-J10 scores; compared with women below the clinical range, women within the clinical range had greater risk of preterm births (RR, 1.16; 95% CI, 1.07-1.26), moderate-to-late preterm births (RR, 1.12; 95% CI, 1.03-1.22), very preterm births (RR, 1.49; 95% CI, 1.18-1.89), and a child born SGA (RR, 1.11; 95% CI, 1.04-1.19).

Conclusions and Relevance

In this cohort study, higher level of maternal autistic traits was associated with increased risk of adverse birth outcomes, particularly very preterm birth. Acknowledging the risks and providing tailored and timely antenatal care support to women with a high level of autistic traits in the general population, particularly women with autistic traits within the clinical range, regardless of formal diagnosis, is warranted.

Risks Associated With Undiagnosed ADHD and/or Autism: A Mixed-Method Systematic Review

BACKGROUND

The two most prevalent neurodevelopmental disorders-Attention Deficit Hyperactivity Disorder (ADHD) and Autism (ASD)-(ASD/ADHD) strongly impact individuals' functions. This is worsened when individuals are undiagnosed and risks such as increased imprisonments, depression or drug misuse are often observed. This systematic review synthesizes the risks associated with late/undiagnosed ASD/ADHD.

METHODS

Four databases were searched (Medline, Scopus, PsychInfor, and Embase). Published studies exploring the impact of undiagnosed ASD/ADHD were included. Exclusion criteria included, lack of diagnosis status, studies not solely on ASD or ADHD, gray literature and studies not in English. The findings were summarize through a narrative synthesis.

RESULTS

Seventeen studies were identified, 14 on ADHD and three on ASD. The narrative synthesis identified three main themes: (1) Health, (2) Offending behavior, and (3) Day-to-day impact. The risks highlighted a significant impact on mental wellbeing and social interactions, higher risks of substance abuse, accidents and offending behavior as well as lower levels of income and education.

DISCUSSION

The findings suggest that undiagnosed ASD/ADHD is linked to many risks and negative outcomes affecting individuals, their families, and the wider society. The restricted number of studies on ASD are a limitation to the generalization of these findings Implications for research and practice are discussed, highlighting the importance of screening and acknowledging the possibility of ASD/ADHD in many settings such as psychiatric and forensic.

Linehan's biosocial model applied to emotion dysregulation in autism: a narrative review of the literature and an illustrative case conceptualization

Emotion dysregulation (ED) is a transdiagnostic difficulty prevalent in autism spectrum condition (ASC). Importantly, recent research has suggested that ED is involved in self-harm and suicidality. Pre-existing models on the etiology of ED in ASC focus mainly on biological factors to ASC features, such as sensory sensitivities, poor flexibility, and sensitivity to change. However, although psychosocial factors seem to play a role in the emergence of ED in ASC as well (e.g., childhood maltreatment and camouflaging), there is a lack of a comprehensive model conceptualizing biosocial factors involved in ED in autistic people. Linehan's biosocial model (1993) is one of the leading etiological models of ED in borderline personality disorder (BPD). It conceptualizes ED as emerging from transactions between a pre-existing emotional vulnerability in the child and an invalidating developmental environment. Beyond its clinical relevance, Linehan's model has gathered empirical evidence supporting its pertinence in BPD and in other psychiatric disorders. Although ASC and BPD are two distinct diagnoses, because they may share ED, Linehan's biosocial model might be useful for understanding the development of ED in ASC. Hence, this article aims to provide an application and extension of Linehan's model to conceptualize ED in ASC. To do so, we conducted a narrative review of the literature on ED and its underlying factors in ASC from a developmental perspective. To investigate the pertinence of the biosocial model applied to ED in autistic people, we were interested on data on (i) ED and its behavioral correlates in ASC, in relation to the biosocial model, (ii) the potential biological and psychosocial correlates of ED in ASC and (iii) the overlapping difficulties in ASC and BPD. Finally, to assess the pertinence of the model, we applied it to the case of an autistic woman presenting with ED and suicidal behaviors. Our review and application to the case of an autistic woman suggest that ED in ASC encompasses factors related to both biological and psychosocial risk factors as conceptualized in the BPD framework, although in both domains ASC-specific factors might be involved.

Measuring the prevalence of autistic traits in a cohort of adults living with HIV or taking HIV pre-exposure prophylaxis and mapping safer-sex barriers and facilitators: a study protocol

INTRODUCTION

Autistic individuals identify with a wider range of sexual orientations than non-autistic individuals, including higher rates of bisexual orientation in autistic men. Gay, bisexual and other men who have sex with men are at greater risk for HIV. Prevalence data of autistic traits in people living with HIV or using Pre-Exposure Prophylaxis (PrEP) for HIV are lacking so far. Such data, combined with insights in barriers and facilitators for safer sex in autistic people living with HIV or using PrEP, are a first step to improve health support for autistic people in HIV clinics. This support is crucial since autistic individuals have worse physical and mental health outcomes. The objective of this research is to determine the prevalence of autistic traits within the group of people living with HIV or using PrEP in Belgium and to describe specific facilitators and barriers for sexual safer behaviour in people living with HIV and PrEP users with autistic traits.

METHODS AND ANALYSIS

The research is a cross-sectional, observational and multicentre study with recruitment of individual participants. The research consists of two phases. In phase 1, adults coming for HIV/AIDS care or HIV PrEP in participating Belgian HIV Reference Centres will be invited to fill in the validated Autism Spectrum Quotient questionnaire. In phase 2, participants with a score above the predefined cut-off for autistic traits (>26), who agreed to be informed about this score, will be invited to complete an additional survey, inquiring facilitators and barriers for sexual safer behaviour.

ETHICS AND DISSEMINATION OF RESULTS

Institutional Review Board Institute of Tropical Medicine Antwerp, 25 July 2022, REF 1601/22 and University Hospital of Antwerp, 12 September 2022, Project ID 3679: BUN B3002022000111. Study results will be published in peer-reviewed journals and presented to Belgian HIV Reference Centres and at conferences.

Shining a Light on a Hidden Population: Social Functioning and Mental Health in Women Reporting Autistic Traits But Lacking Diagnosis

Female Phenotype Theory (FPT) suggests that autistic women often present with less obvious social impairments than autistic men. We examined the possibility of an exaggerated female phenotype among undiagnosed but probably autistic women. In two nationwide online surveys, we compared self-reported social functioning and mental health between diagnosed autistic women and women without diagnosis who scored ≥ 32 on the Autism Quotient. Compared to diagnosed autistic women, probably autistic women had higher empathy and general social functioning, and were more likely to have received a diagnosis of Borderline Personality Disorder. Autistic women had typically received more mental health diagnoses prior to their ASC diagnosis than autistic men. These findings shed light on the history of misdiagnosis experienced by many autistic women.

Development, delivery, and evaluation of a training program for the early identification of autism: Monitoring of Social Attention, Interaction, and Communication

Introduction

Early identification of Autistic children is an important precursor to diagnosis, and access to supports and services. Here we describe the training of the maternal and child health (MCH) workforce in the state of Victoria, Australia in the early identification of infants and toddlers with a high likelihood of autism.

Methods

In 2019, 1,428 MCH nurses completed early autism training held at venues across the state, with an additional 82 nurses completing online-only training. A training needs analysis enabled the research team to determine the workforce's current skill and knowledge levels, and to identify knowledge gaps, training needs and workplace barriers. The professional development program, known as Monitoring of Social Attention, Interaction, and Communication (MoSAIC), comprised: online pre-workshop modules; a face-to-face instructor-led workshop, which included the use of the Social Attention and Communication-Revised (SACS-R) tool; and online post-workshop modules, which included a recording of a face-to-face workshop with all accompanying resources. This was the first time that the MCH workforce received this training package. Attendees were asked to complete a training satisfaction survey immediately following the face-to-face instructor-led workshop and a follow-up survey regarding their autism knowledge and SACS-R implementation 4-6 weeks after the workshop.

Results

Over 90% (n = 325) of MCH nurses who completed the training satisfaction survey agreed or strongly agreed with statements that the training was clear and of high quality. Most nurses also reported that the training was well-presented and that they would recommend it to a colleague. In the 6 months following the training, a total of 82,581 SACS-R assessments were conducted by the MCH workforce, reflecting that MCH nurses had successfully integrated SACS-R assessments into their work practice after receiving the early autism identification training.

Discussion

This study demonstrated that training on the early identification of autism can be successfully designed, customized, and delivered to a large primary healthcare workforce for universal developmental surveillance of autism.

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.

Understanding the Self-identification of Autism in Adults: a Scoping Review

Adults are increasingly self-identifying as autistic, and reporting problems being referred for an autism diagnostic assessment. This scoping review aims to ascertain: (1) what research has been conducted on the self-identification process of autism in adults, who do and do not have a formal diagnosis of autism, and (2) which aspects of the self-identification process could be used to improve the referral and the diagnostic process of an adult autism assessment. The main themes identified were: the diagnostic process from a client´s perspective; the process of self-identifying as autistic from a lifespan perspective; an autistic identity; sexual identity and experiences, and the perception of autism as a difference or a disability. These themes could positively enhance the referral and diagnostic process.

Love, Joy, and a Lens of Childhood Trauma: Exploring Factors That Impact the Mental Health and Well-Being of Autistic Parents via Iterative Phenomenological Analysis

Background

The autistic community have called for an increase in autism research exploring the lifespan experiences of autistic people. Researchers have notably neglected the parenting experiences of autistic adults. We aimed to study the factors that impact the mental health of autistic parents. We also explored the possible influence of childhood trauma.

Methods

Nine autistic parents took part in remote semi-structured interviews. We used participants' chosen communication modalities during interviews to facilitate accessibility. We carried out data analysis using the principles of Iterative Phenomenological Analysis, a qualitative approach where meaning is co-constructed by both the participant's interpretation of their personal experience and the researcher's subjective interpretation.

Results

We identified three superordinate themes: Identity and Purpose; Looking Through a Lens of Trauma; and External Factors. Our participants described intimate connections with their children, who were sources of love and joy. Their childhood trauma influenced their parenting experiences. They experienced extreme empathy, perfectionism, and a drive to protect their children from the same trauma. We found that professionals' acceptance and awareness of autism was essential for positive outcomes during interactions with participants. Participants also experienced pervasive sensory overload from their environments, related to a loss of trusted coping mechanisms when they became parents.

Conclusions

Our study draws attention to the influence of childhood trauma on the parenting experience of autistic adults. We reveal an unexplored long-term impact of childhood trauma resulting from a lack of support and othering of autistic children. Professionals should consider that autistic parents may be parenting through a lens of historical trauma. Professionals should be trained in trauma-informed approaches for providing support. Researchers should investigate this phenomenon to explore how this knowledge can be used to inform practise. Researchers should also investigate wider systemic and societal issues that have an impact on the mental health of autistic parents.

"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.

“I Always Knew I Was Different”: Experiences of Receiving a Diagnosis of Autistic Spectrum Disorder in Adulthood—a Meta-Ethnographic Systematic Review

A broadening of diagnostic criteria and increased awareness of autism has led to a large number of individuals whose difficulties remained undetected until adulthood. This systematic review aimed to synthesise empirical evidence of the experience of individuals who received their diagnosis of autism in adulthood. Eight studies met the inclusion criteria. A meta-ethnographic approach was used to synthesise the findings. Analysis revealed two meta-themes: feeling “like an alien” and the “not guilty” verdict, each with three associated subthemes. The findings indicate the need for timely diagnosis and provision of post-diagnostic support to alleviate the mental health implications of not having a framework to understand one’s experiences and to support the process of adjustment to the diagnosis.

Does learning you are autistic at a younger age lead to better adult outcomes? A participatory exploration of the perspectives of autistic university students

LAY ABSTRACT

People learn they are autistic at different ages. We wanted to know if telling kids they are autistic earlier helps them feel better about their lives when they grow up. We are a team of autistic and non-autistic students and professors. Seventy-eight autistic university students did our online survey. They shared how they found out they were autistic and how they felt about being autistic. They also shared how they feel about their lives now. Around the same number of students learned they were autistic from doctors and parents. Students who learned they were autistic when they were younger felt happier about their lives than people who learned they were autistic when they were older. Students who learned they were autistic when they were older felt happier about being autistic when they first found out than people who did not have to wait as long. Our study shows that it is probably best to tell people they are autistic as soon as possible. The students who did our study did not think it was a good idea to wait until children are adults to tell them they are autistic. They said that parents should tell their children they are autistic in ways that help them understand and feel good about who they are.

A molecular framework for autistic experiences: Mitochondrial allostatic load as a mediator between autism and psychopathology

Molecular autism research is evolving toward a biopsychosocial framework that is more informed by autistic experiences. In this context, research aims are moving away from correcting external autistic behaviors and toward alleviating internal distress. Autism Spectrum Conditions (ASCs) are associated with high rates of depression, suicidality and other comorbid psychopathologies, but this relationship is poorly understood. Here, we integrate emerging characterizations of internal autistic experiences within a molecular framework to yield insight into the prevalence of psychopathology in ASC. We demonstrate that descriptions of social camouflaging and autistic burnout resonate closely with the accepted definitions for early life stress (ELS) and chronic adolescent stress (CAS). We propose that social camouflaging could be considered a distinct form of CAS that contributes to allostatic overload, culminating in a pathophysiological state that is experienced as autistic burnout. Autistic burnout is thought to contribute to psychopathology via psychological and physiological mechanisms, but these remain largely unexplored by molecular researchers. Building on converging fields in molecular neuroscience, we discuss the substantial evidence implicating mitochondrial dysfunction in ASC to propose a novel role for mitochondrial allostatic load in the relationship between autism and psychopathology. An interplay between mitochondrial, neuroimmune and neuroendocrine signaling is increasingly implicated in stress-related psychopathologies, and these molecular players are also associated with neurodevelopmental, neurophysiological and neurochemical aspects of ASC. Together, this suggests an increased exposure and underlying molecular susceptibility to ELS that increases the risk of psychopathology in ASC. This article describes an integrative framework shaped by autistic experiences that highlights novel avenues for molecular research into mechanisms that directly affect the quality of life and wellbeing of autistic individuals. Moreover, this framework emphasizes the need for increased access to diagnoses, accommodations, and resources to improve mental health outcomes in autism.

A survey of autistic adults, relatives and clinical teams in the United Kingdom: And Delphi process consensus statements on optimal autism diagnostic assessment for adults

LAY ABSTRACT

Living with undiagnosed autism can be distressing and may affect mental health. A diagnosis of autism can help self-awareness and self-understanding. However, it can be difficult for adults to access an autism assessment. Clinicians also sometimes find it hard to identify autism in adults. This may mean an autism diagnosis is delayed or missed. In this study, we asked autistic adults, relatives and clinicians how to improve this. The study was in two stages. In the first stage (stage 1), 343 autistic adults and 45 relatives completed a survey. In the survey, we asked questions about people's experiences of UK autism assessment services for adults. Thirty-five clinicians completed a similar survey. Clinicians reported that some autism assessment teams lacked key professionals, for example, psychologists and occupational therapists. We used the information from the three separate surveys to create 13 statements describing best autism assessment services for adults. In stage 2, we asked clinicians for their views on the 13 statements. Clinicians agreed with 11 of the statements. Some autistic adults, relatives and clinicians were positive about autism assessment services, and many also described areas that could be improved. The study findings can be used to improve UK adult autism assessment services and may be helpful for service developments worldwide.

Exploring the Experience of Seeking an Autism Diagnosis as an Adult

Background

Emerging research suggests that seeking an autism diagnosis as an adult is usually difficult and time-consuming but brings relief once a diagnosis is made. This study explored the experience of the pathway to an autism diagnosis during adulthood for adults living in Australia.

Methods

We conducted a qualitative phenomenological study and interviewed 13 adults who identified as autistic about their pathway to autism diagnosis in their mode of choice. Spoken interviews were transcribed verbatim, and transcripts were analyzed by using a thematic approach.

Results

Data analysis resulted in 6 themes and 20 meaning units that described the experiences of adults seeking an autism diagnosis in Australia. These themes involved two interwoven journeys that spanned before, during, and after the diagnostic process. The personal journey involved feeling different, considering autism, and living as autistic, whereas the clinical journey involved missed opportunities, varied diagnostic experiences, and absent supports.

Conclusions

Given the potential benefits for adults obtaining a formal autism diagnosis and accessing post-diagnostic supports, it is important that health professionals and governments collaborate to reduce access barriers and ensure adequate services are available. The findings from this study informed the development of Australia's national guideline for autism diagnosis.

"We couldn't think in the box if we tried. We can't even find the damn box": A qualitative study of the lived experiences of autistic adults and relatives of autistic adults

Autistic children grow to become autistic adults, and autism is increasingly diagnosed in adulthood and later life. This qualitative study aimed to understand experiences of autism throughout adulthood. A national cohort study of autistic adults and relatives of autistic adults (ASC-UK), enabled purposive recruitment of a diverse sample. Semi-structured interviews were conducted with 29 autistic adults (aged 20-71 years), mostly diagnosed in adulthood, and 16 relatives (aged 31-81 years) of autistic adults diagnosed across both childhood and adulthood (including some with learning disability). Interview topics included health, relationships, education, employment, quality of life and everyday experiences. Thematic analysis of the accounts of the autistic adults identified six key themes relating to their experiences: (1) diagnosis as validating yet limiting; (2) supportive and non-supportive social agents; (3) the "invisibility" of the needs of autistic adults; (4) health in the context of autism; (5) staying 'outside' the circle; and (6) multiple lives with autism. Data from relatives about autistic adult experiences gave additional perspectives on these themes. Experiences reported in other studies-of 'difference' from others, challenges of social engagement, and learning to 'conform' to society's expectations-were evident and relevant to male and female autistic adults, across all age groups, and unrelated to stage of life when diagnosed. Some expressed disappointment with their lives, but others were proud of their achievements. Education and employment, whilst challenging for many, were also rewarding for some. Health care and social services were often experienced as inaccessible, inappropriate, or lacking understanding of the individual's needs. We conclude that greater public understanding of autism as experienced in adulthood is needed. Key priorities are improving the availability of 'appropriate' health and social care services for autistic adults and families, and providing practical support to enable enhanced participation in life.

What Is Autistic Burnout? A Thematic Analysis of Posts on Two Online Platforms

Background

Compared with adults in the general population, autistic adults are more likely to experience poor mental health, which can contribute to increased suicidality. While the autistic community has long identified autistic burnout as a significant mental health risk, to date, only one study has been published. Early research has highlighted the harmful impact of autistic burnout among autistic adults and the urgent need to better understand this phenomenon.

Methods

To understand the lived experiences of autistic adults, we used data scraping to extract public posts about autistic burnout from 2 online platforms shared between 2005 and 2019, which yielded 1127 posts. Using reflexive thematic analysis and an inductive "bottom-up" approach, we sought to understand the etiology, symptoms, and impact of autistic burnout, as well as prevention and recovery strategies. Two autistic researchers with self-reported experience of autistic burnout reviewed the themes and provided insight and feedback.

Results

We identified eight primary themes and three subthemes across the data. (1) Systemic, pervasive lack of autism awareness. (1.1) Discrimination and stigma. (2) A chronic or recurrent condition. (3) Direct impact on health and well-being. (4) A life unlived. (5) A blessing in disguise? (6) Self-awareness and personal control influence risk. (6.1) "You need enough balloons to manage the weight of the rocks." (7) Masking: Damned if you do, damned if you don't. (8) Ask the experts. (8.1) Stronger together. The overarching theme was that a pervasive lack of awareness and stigma about autism underlie autistic burnout.

Conclusions

We identified a set of distinct yet interrelated factors that characterize autistic burnout as a recurring condition that can, directly and indirectly, impact autistic people's functioning, mental health, quality of life, and well-being. The findings suggest that increased awareness and acceptance of autism could be key to burnout prevention and recovery.

Case Report: Mechanisms in Misdiagnosis of Autism as Borderline Personality Disorder

Autistic individuals without intellectual disabilities are sometimes not diagnosed until adolescence/adulthood. Due to increased risk of co-occurring mental health problems, these individuals may initially be referred to general, mental health services and not always be identified as autistic; some may be misdiagnosed with personality disorder (PD) prior to identification of autism. To explore possible mechanisms in misdiagnosis of autism, we report on the case of a young man with severe, non-suicidal self-injury (NSSI) and attention deficit disorder (ADD) who had been diagnosed with and treated for borderline PD prior to being diagnosed with autism. Following reassessment by mental health clinicians with experience of working with autistic individuals, the patient was diagnosed with autism, ADD, and depression—but not PD. Experiences from this case suggest that presence of co-occurring NSSI, depression, and ADD, as well as lack of comprehensive assessment and lack of autism knowledge in general mental health services, may contribute to risk that autism is misdiagnosed as PD. These findings highlight the need for autism expertise in general mental health services to facilitate appropriate diagnosis for autistic individuals who encounter these services, as well as the importance of undertaking comprehensive assessments.

Intolerance of Uncertainty and Challenges in Decision-making in Adults with High-Functioning Autism

<p style="text-align: justify;">Individuals with high-functioning autism have difficulties in decision-making in face of incomplete or ambiguous information, particularly in the context of social interaction. Tasks demanding an immediate response or deviation from the usual behavior make them feel excessive anxiety which restricts their social and professional activity. Attempts to camouflage their conservatism to others are one of the risk factors for comorbid depression. Therefore, they avoid new and non-routine situations, thus restricting their own social activity and professional development. On the other hand, insisting on sameness and clarity may give individuals with autism an advantage in long-lasting monotonous tasks. The aim of this review is to consider these symptoms from the perspective of predictive coding. A range of experimental studies has shown that most of the subjects with autism have difficulty in predicting the outcomes based on the cumulative history of interacting with the environment, as well as updating expectations as new evidence becomes available. These peculiarities of the analysis and pragmatic weighting of information may cause the trait intolerance of uncertainty and novelty avoidance of most people with autism.</p>

An evaluation of the online post-diagnostic groups facilitated by the autism spectrum condition service at Gloucestershire Health and Care NHS

Purpose

Autism spectrum condition (ASC) is a lifelong developmental condition. According to research, it is recommended that those diagnosed with ASC should be offered post-diagnosis support to explore their diagnosis (Punshow, Skirrow and Murphy, 2009). The ASC Diagnostic Assessment Service at Gloucestershire Health Care (GHC) NHS Foundation Trust offers an assessment service to adults (18+) located within Gloucestershire. All those who receive a diagnosis are then invited to a 7-week post-diagnostic group facilitated by the multidisciplinary team. This service evaluation aimed to evaluate the aforementioned group so that it can be improved upon and thus provide a better service for future clients.

Design/methodology/approach

In total, 14 participants (6 males, 8 females) were interviewed for the purpose of this evaluation following their attendance at these groups.

Findings

The interview transcripts then underwent thematic analysis with four themes identified; “Autistic Community”, “Experience of Being Part of an Online Group”, “Opportunity for Consolidation”, and “Design Considerations and Improvements”. Further sub-themes were also identified. Overall, the service evaluation identified that the group provided a platform for sharing experiences and gaining a sense of belonging. It also highlighted that individuals have different preferences for whether groups should be facilitated online or face-to-face, and also different preferences for the duration of sessions. Further analysis also revealed the suggestion that the final session, for family and friends, should be optional so that those without a support network, do not need to attend as this caused unease in some. Further findings were also identified.

Originality/value

To the authors’ knowledge, existing articles have only focused on the evaluation of the availability of post-diagnostic provision and autistic individuals’ general impression of it rather than an in-depth evaluation of a specific type of support.

'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.

Camouflaging Intent, First Impressions, and Age of ASC Diagnosis in Autistic Men and Women

Camouflaging of autistic traits may make autism harder to diagnose. The current study evaluated the relations between camouflaging intent, first impressions, and age of autism diagnosis. Participants comprised autistic and non-autistic adults (n = 80, 50% female) who completed the Camouflaging of Autistic Traits Questionnaire. They were later video-recorded having a conversation with a person unaware of their diagnostic status. Ten-second clips from half these videos were later shown to 127 non-autistic peers, who rated their first impressions of each participant. Results showed that autistic participants were rated more poorly on first impressions, males were rated less favourably than females, and male raters were particularly harsh in their evaluations of autistic males. Camouflaging intent did not predict first impressions but better first impressions were linked with a later age of diagnosis.

Personal Identity After an Autism Diagnosis: Relationships With Self-Esteem, Mental Wellbeing, and Diagnostic Timing

Adults are increasingly seeking autism diagnoses, although less is known about their experiences of diagnosis and personal identity (i.e., autism as part of "me"), and how this relates to self-esteem and wellbeing. One-hundred and fifty-one autistic adults completed an online survey including measures of self-esteem, psychological wellbeing, and autistic personal identity, which considered whether participants took pride in or were dissatisfied with being autistic. Fifty-four participants answered a qualitative question about the impact of receiving an autism diagnosis on their sense of self. Regression analyses found that greater time elapsed since diagnosis related to less dissatisfaction with autistic personal identity. We also found that more dissatisfaction with autistic personal identity predicted lower self-esteem, and more autism pride predicted higher self-esteem. Content analysis of participants' experiences supported the quantitative findings and was suggestive of an emotive post-diagnostic adjustment process. Future research should aim to identify ways to promote the development of a positive autistic personal identity post-diagnosis in adulthood.

The Predictive Value of the AQ and the SRS-A in the Diagnosis of ASD in Adults in Clinical Practice

Questionnaires are widely used in autism assessment. However, their psychometric properties are generally not evaluated in clinical practice, and the comparability and applicability of such research is limited because questionnaires are often not simultaneously evaluated. This certainly pertains to predictive values which are highly population and setting specific. This study evaluated the power of AQ and SRS-A in predicting an ASD diagnosis within the same clinical population. The patient records of 92 adults, referred for autism assessment, were analyzed. The AQ proved somewhat better than the SRS-A at discriminating and predicting autism. The predictive values of both questionnaires were lower than reported in general population studies. Psychometric results in core publications appear less representative for clinical practice.

The Relationship of Age with the Autism-Spectrum Quotient Scale in a Large Sample of Adults

Background: The historical focus on autism as a childhood disorder means that evidence regarding autism in adulthood lags significantly behind research in other age groups. Emerging studies on the relationship of age with autism characteristics do not target older adult samples, which presents a barrier to studying the important variability that exists in life span developmental research. This study aims to further our understanding of the relationship between the Autism-Spectrum Quotient Scale and age in a large adult sample. Methods: The present study examines the relationship of Autism-Spectrum Quotient Scale (AQ) scores with age in 1139 adults, ages 18-97 years. Participants came from three distinct samples-a sample of primarily students, a sample of MTurk participants, and a sample of primarily community dwelling older adults. The majority of the participants did not self-report an autism diagnosis (91%), were female (67%), and identified as White (81%). Participants completed the AQ primarily via online surveys. Researchers scored the AQ following six common scoring practices. Results: Results of preregistered analyses indicate that autism characteristics measured by the AQ are not strongly associated with age (r values from -0.01 to -0.11). Further findings indicate that the measurement of autism characteristics is consistent across age into late life using both multiple groups and local structural equation modeling approaches to measurement invariance (comparative fit indices = 0.82-0.83, root mean square error = 0.06) as well as reliability analysis. Finally, demographic and autism-related variables (sex, race, self-identified autism spectrum disorder diagnosis, and degree of autism characteristics) did not moderate the relationship between age and autism characteristics. Conclusion: These results suggest that self-reports of autism characteristics using the AQ do not vary strongly by age in this large age-representative sample. Findings suggest that the AQ can potentially serve as a useful tool for future research on autism across the life span. Important limitations on what we can learn from these findings point toward critical avenues for future research in this area.

Lay summary

Why was this study done?: Self-report questionnaires of autism characteristics are a potentially important resource for studying autism in adulthood. This study sought to provide additional information about one of the most commonly used self-report questionnaires, the Autism-Spectrum Quotient Scale (AQ), across adulthood.What was the purpose of this study?: This study intended to determine if there is a relationship between scores on the AQ and age. Researchers also worked to identify which of the multiple different ways of scoring the AQ worked best across adulthood.What did the researchers do?: Researchers collected data from over a thousand participants aged 18-97 years. Participants from three different age groups completed online surveys to self-report their levels of autism characteristics on the AQ. Researchers tested the relationship between AQ scores and age with six different commonly used ways to calculate AQ scores. Researchers used multiple statistical techniques to evaluate various measurement properties of the AQ.What were the results of the study?: The results indicate that autism characteristics measured by the AQ are not strongly associated with age. Along with that, there is evidence that certain approaches to measuring of autism characteristics are consistent across age into late life and do not vary with demographic and autism-related factors.What do these findings add to what was already known?: These results add to the growing evidence that self-reports of autism characteristics using the AQ in general samples are not strongly associated with age across adulthood. These findings also provide guidance about ways of scoring the AQ that work well through late life.What are potential weaknesses in the study?: While the AQ has a degree of relationship with autism diagnoses, this is far from perfect and has not been evaluated in the context of aging research. Therefore, findings from the present research must be carefully interpreted to be about autism characteristics not diagnoses. The sample was also limited in a number of other ways. As in any studies including a broad age range of individuals, the oldest participants are likely quite healthy, engaged individuals. This may particularly be the case given the higher mortality rates and health challenges seen with autism. Similarly, as with any self-report research, this research is limited to those individuals who could answer questions about their autism characteristics. The sample was also predominantly White and nonautistic. Finally, the research was limited to one point in time and so cannot tell us about how autism characteristics may change across adulthood.How will these findings help autistic adults now or in the future?: These findings support the potential for the AQ to be a useful tool for future research on autism in adulthood. For example, researchers can use measures such as the AQ to study how autism characteristics change over time or are associated with aging-related issues such as changes in physical health and memory. Such research may be able to provide a better understanding of how to support autistic individuals across adulthood.

Automating autism assessment: What AI can bring to the diagnostic process

This paper examines the use of artificial intelligence (AI) for the diagnosis of autism spectrum disorder (ASD, hereafter autism). In so doing we examine some problems in existing diagnostic processes and criteria, including issues of bias and interpretation, and on concepts like the 'double empathy problem'. We then consider how novel applications of AI might contribute to these contexts. We're focussed specifically on adult diagnostic procedures as childhood diagnosis is already well covered in the literature.

Supporting Newly Identified or Diagnosed Autistic Adults: An Initial Evaluation of an Autistic-Led Programme

Sixteen adults (diagnosed or self-identified as autistic) participated in one of two iterations of a ten-week autistic-led programme, aimed at helping autistic adults learn more about autism within a peer group context. Motivations for taking part in the programme included a desire for: (1) exploration of autism; (2) empowerment; and (3) the development of practical strategies and coping mechanisms. Interviews were conducted upon completion of the programme and again 6 months later. Using thematic analysis, three themes were identified: (1) appreciation of the autistic-led nature of the programme; (2) unity in diversity; and (3) developing a positive, practical outlook on autism. These promising initial results highlight the value of autistic-led peer support for those recently diagnosed/identified as autistic.

Cancer Care of Children, Adolescents and Adults With Autism Spectrum Disorders: Key Information and Strategies for Oncology Teams

Delivering optimal cancer care to children, adolescents and adults with ASD has recently become a healthcare priority and represents a major challenge for all providers involved. In this review, and after consideration of the available evidence, we concisely deliver key information on this heterogenous group of neurodevelopmental disorders, as well as recommendations and concrete tools for the enhanced oncological care of this vulnerable population of patients.

Automatic Classification of Adult Males With and Without Autism Spectrum Disorder by Non-contact Measurement of Autonomic Nervous System Activation

People with autism spectrum disorder (ASD) exhibit atypicality in various domains of behavior. Previous psychophysiological studies have revealed an atypical pattern of autonomic nervous system (ANS) activation induced by psychosocial stimulation. Thus, it might be feasible to develop a novel assessment tool to evaluate the risk of ASD by measuring ANS activation in response to emotional stimulation. The present study investigated whether people with ASD could be automatically classified from neurotypical adults based solely on physiological data obtained by the recently introduced non-contact measurement of pulse wave. We video-recorded faces of adult males with and without ASD while watching emotion-inducing video clips. Features reflective of ANS activation were extracted from the temporal fluctuation of facial skin coloration and entered into a machine-learning algorithm. Though the performance was modest, the gradient boosting classifier succeeded in classifying people with and without ASD, which indicates that facial skin color fluctuation contains information useful for detecting people with ASD. Taking into consideration the fact that the current study recruited only high-functioning adults who have relatively mild symptoms and probably developed some compensatory strategies, ASD screening by non-contact measurement of pulse wave could be a promising assessment tool to evaluate ASD risk.

Commentary on “being diagnosed with autism in adulthood: a personal case study”

Purpose

The purpose of this paper is to provide a commentary on “being diagnosed with autism in adulthood: a personal case study”.

Design/methodology/approach

A commentary on an individual’s personal experiences of being referred to autism assessment services and subsequently receiving a diagnosis of autism in adulthood.

Findings

Many individuals are not diagnosed with autism until their adult life, and as a result, miss the benefits of timely introduction of sources of support, such as during their schooling. Receiving an autism diagnosis can come as a relief and promote self-understanding, but availability of high-quality post-diagnostic support services and accommodating employers are both highly important.

Originality/value

A commentary on an original viewpoint is published in this special edition on gender and diversity.

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.
