Life expectancy and years of life lost for adults with diagnosed ADHD in the UK: matched cohort study.

Background: Nearly 3% of adults have attention-deficit and hyperactivity disorder (ADHD), although in the UK, most are undiagnosed. Adults with ADHD on average experience poorer educational and employment outcomes, worse physical and mental health and are more likely to die prematurely. No studies have yet used mortality data to examine the life expectancy deficit experienced by adults with diagnosed ADHD in the UK or worldwide.

A systematic review of ecological momentary assessment in autism research.

Ecological momentary assessments assess people's in-the-moment thoughts and behaviours in their daily lives in natural environments. The number of ecological momentary assessment studies with autistic people has increased over the last decade. For the first time, this review (1) summarises how well ecological momentary assessment works for allowing autistic people to describe and express their thoughts, emotions and experiences, and (2) provides suggestions for the design of ecological momentary assessment to make this research method more accessible to future autistic participants.

A systematic review and meta-analysis of the relationship between sensory processing differences and internalising/externalising problems in autism.

There is evidence to suggest that sensory processing differences (SPDs) to external stimuli are a plausible underlying mechanism for mental health problems among autistic people. In the current systematic review, we examined the associations between, on the one hand, eleven types of SPDs and, on the other hand, internalising and externalising problems. The literature search was conducted on five databases (MEDLINE, PsycINFO, Web of Science, EMBASE, and CINAHL) between 1990 and August 2024.

'It's designed for someone who is not me': A reflexive thematic analysis of the unmet healthcare support needs in UK autistic adults aged 65 years and over.

Autistic people often face both physical and mental health challenges throughout their lives, which can lead to a higher risk of premature death due to health inequalities. However, we know very little about the healthcare experiences of autistic older adults. In this study, we talked with 19 autistic adults aged 65 years or above living in the United Kingdom.

Perceived changes in mental health and social engagement attributed to a single psychedelic experience in autistic adults: results from an online survey.

Rationale: Anecdotal reports suggest that psychedelic drugs can improve psychological wellbeing and social engagement in autistic people. However, there are few contemporary studies on this topic.

Objectives: To examine autistic participants' experiences with psychedelic drugs and the extent to which they attributed changes in mental health and social engagement to their most 'impactful' psychedelic experience.

Validation of the camouflaging autistic traits questionnaire short form (CATQ-SF).

Background: Camouflaging of autistic traits involves hiding or compensating for autistic characteristics, often due to stigma or a desire to fit in with others. This behaviour has been associated with mental health issues in autistic individuals. The 2 5-item Camouflaging Autistic Traits Questionnaire (CAT-Q) is the most commonly used self-report measure of camouflaging.

The overlap of disordered eating, autism and ADHD: future research priorities as identified by adults with lived experience.

The focus of mental health research in emerging fields should be driven by the priorities of people with relevant lived experience. Autism and ADHD are childhood-onset neurodevelopmental conditions that are associated with a range of health inequalities, including increased risk for eating disorders. The evidence base for how best to support neurodivergent individuals who experience disordered eating is still in its infancy, but research suggests that existing clinical approaches are not currently fit for purpose.

Diagnosis of common health conditions among autistic adults in the UK: evidence from a matched cohort study.

Background: Autistic people are disproportionately likely to experience premature mortality and most mental and physical health conditions. We measured the incidence of diagnosed conditions accounting for the most disability-adjusted life years in the UK population according to the Global Burden of Disease study (anxiety, depression, self-harm, harmful alcohol use, substance use, migraine, neck or back pain, and gynaecological conditions).

Methods: Participants were aged 18 years or above and had an autism diagnosis recorded in the IQVIA Medical Research Database between 01/01/2000 and 16/01/2019.

Approaches to improving mental healthcare for autistic people: systematic review.

Background: Autistic people have a high likelihood of developing mental health difficulties but a low chance of receiving effective mental healthcare. Therefore, there is a need to identify and examine strategies to improve mental healthcare for autistic people.

Aims: To identify strategies that have been implemented to improve access, experiences of care and mental health outcomes for autistic adults, and to examine evidence on their acceptability, feasibility and effectiveness.

Potential mechanisms underlying the association between feeding and eating disorders and autism.

There is a reliable association between autism and Feeding and Eating Disorders. Concerningly, where these two conditions co-occur, clinical outcomes of Feeding and Eating Disorders are significantly worse, and treatment less effective, than when the Feeding and Eating Disorders occur in neurotypical individuals. Problematically, the reason for the association between autism and Feeding and Eating Disorders is poorly understood, which constrains advances in clinical care.

Reliability and validity of the Japanese version of the camouflaging autistic traits questionnaire.

This study investigated the factor structure and determined the reliability and validity of the Camouflaging Autistic Traits Questionnaire-Japanese version (CAT-Q-J) among 204 autistic and 410 non-autistic people. Since a confirmatory factor analysis revealed no factor validity of the CAT-Q-J for both autistic and non-autistic adults, an exploratory factor analysis was conducted to ensure the psychometric properties matched those of the original scale as much as possible. The results showed the CAT-Q-J comprised three subscales, a four-item compensation subscale, a five-item masking scale, and a five-item assimilation subscale.

Utility of the 3Di short version in the identification and diagnosis of autism in children at the Kenyan coast.

Introduction: The precise epidemiological burden of autism is unknown because of the limited capacity to identify and diagnose the disorder in resource-constrained settings, related in part to a lack of appropriate standardised assessment tools and health care experts. We assessed the reliability, validity, and diagnostic accuracy of the Developmental Diagnostic Dimensional Interview (3Di) in a rural setting on the Kenyan coast.

Methods: Using a large community survey of neurodevelopmental disorders (NDDs), we administered the 3Di to 2,110 children aged between 6 years and 9 years who screened positive or negative for any NDD and selected 242 who had specific symptoms suggestive of autism based on parental report and the screening tools for review by a child and adolescent psychiatrist.

Measurement invariance of the parent-reported Strengths and Difficulties Questionnaire in autistic adolescents.

Autistic people are more likely than non-autistic people to experience mental health difficulties. The Strengths and Difficulties Questionnaire is often used to screen for these difficulties and to otherwise make important decisions about mental health treatment and research in populations of autistic people. However, this study suggests that parent-reported Strengths and Difficulties Questionnaire scores may not be useful for comparing autistic and non-autistic adolescents at 11, 14 and 17 years old, as well as screening for mental health conditions in autistic adolescents.

Improving Diagnostic Procedures in Autism for Girls and Women: A Narrative Review.

Biases exist in the diagnostic process for autism spectrum disorder (henceforth "autism"), which result in some girls and women being diagnosed later or missed entirely. Current diagnostic tools may not capture the full range of behavioural presentations of autism, leading to under-identification. This review explores why these biases may occur, and how diagnostic procedures could be adapted to better identify autistic girls and women.

Autistic identity: A systematic review of quantitative research.

Autism can be considered both a personal and social identity. Identifying the factors contributing to positive Autistic identity development is crucial given the potential implications for mental health and wellbeing. In this systematic review, we aimed to synthesize quantitative literature on Autistic identity to identify the (individual and environmental) factors associated with Autistic identity, and to ascertain the relationship between Autistic identity and mental health and wellbeing.

Estimating life expectancy and years of life lost for autistic people in the UK: a matched cohort study.

Background: Previous research has shown that people who have been diagnosed autistic are more likely to die prematurely than the general population. However, statistics on premature mortality in autistic people have often been misinterpreted. In this study we aimed to estimate the life expectancy and years of life lost experienced by autistic people living in the UK.

The association between social camouflage and mental health among autistic people in Japan and the UK: a cross-cultural study.

Background: To examine the relationship between social camouflage and mental health in Japanese autistic adults and make an international comparison with a sample from the UK.

Methods: This study analysed secondary data of participants with a self-reported diagnosis of autism from Japan (N = 210; 123 men and 87 women) and the UK (N = 305; 181 women, 104, men, and 18 nonbinary). The relationships between the quadratic term of the Camouflaging Autistic Traits Questionnaire and mental health scales, including depression and anxiety, were assessed.

Understanding anxiety experienced by young males with Duchenne muscular dystrophy: a qualitative focus group study.

In this multi-methods study we explored the characteristics, causes and impact of anxiety in Duchenne muscular dystrophy (DMD) from the perspective of young males with DMD and their parents. Eight young males with DMD (7-18 years) and 14 parents participated in separate focus groups. Perspectives on anxiety were explored using semi-structured interview schedules.

Does camouflaging predict age at autism diagnosis? A comparison of autistic men and women.

It is frequently reported that females are likely to receive an autism diagnosis at a later age than their male counterparts, despite similar levels of autistic traits. It has been suggested that this delay in diagnosis may in part reflect the propensity of females, more than males, to engage in camouflaging behaviors that reduce the appearance of autism-related traits. This article presents two studies which examined the relationship between gender/sex, camouflaging, and age at diagnosis in two samples of (cis-gender) autistic adults.

Effectiveness of primary care psychological therapy services for treating depression and anxiety in autistic adults in England: a retrospective, matched, observational cohort study of national health-care records.

Background: Autistic adults report a higher prevalence of anxiety and depression than adults without identified autism but have poorer access to appropriate mental health care. Evidence-based psychological therapies are recommended in treatment guidelines for autistic adults, but no study has investigated their effectiveness in large samples representative of the autistic population accessing routine care. This study aimed to examine therapy outcomes for autistic adults in a primary care service.

Short report: Evaluation of wider community support for a neurodiversity teaching programme designed using participatory methods.

Children with diagnoses such as autism, attention-deficit/hyperactivity disorder (ADHD), dyslexia and so on often experience bullying at school. This group can be described as , meaning they think and process information differently from most people. Previous research suggests that increasing people's knowledge can be an effective way to reduce stigma and bullying.
