Is quality of life related to high autistic traits, high ADHD traits and their Interaction? Evidence from a Young-Adult Community-Based twin sample.

This study explored whether high autistic traits, high attention deficit hyperactivity disorder (ADHD) traits and their interaction were associated with quality of life (QoL) in a sample of 556 of young-adult twins (Mean age 22 years 5 months, 52% Female). Four participant groups were created: high autistic traits, high ADHD traits, high autistic/ADHD traits, and low ADHD/autistic traits. High autistic traits were associated with lower QoL across domains (physical, psychological, social, and environmental). High ADHD traits associated with lower physical, psychological, and environmental QoL. The interaction of autistic and ADHD traits was not significant in any domain. While mental health difficulties were associated with lower QoL, after accounting for mental health, most relationships between autistic traits, ADHD traits and QoL remained.

Autism Diagnostic Assessments With Children, Adolescents, and Adults Prior to and During the COVID-19 Pandemic: A Cross-Sectional Survey of Professionals.

Background: Access to timely high quality autism diagnostic assessments has traditionally been patchy; many individuals wait months, if not years, for an appointment. The onset of the COVID-19 pandemic has likely impacted autism diagnostic services. This study investigated professionals' experiences of, and thoughts about: (1) how autism diagnostic assessments were conducted before the pandemic; (2) adaptations to service provision because of the pandemic; and (3) challenges, risks, advantages and opportunities associated with autism assessments conducted via online platforms (telehealth). Method: Fifty-two professionals, based in different autism diagnostic services and working with children, adolescents and/or adults, completed an online cross-sectional survey in August and September 2020. This comprised demographic questions (about professionals' roles and experiences), and closed and open questions about service provision and telehealth autism assessments. Results: There was substantial variation in how autism assessments were conducted prior to and during the pandemic; for example, in relation to the number of professionals involved in the assessment and types of structured, semi-structured and unstructured measures used to conduct this. Fifty-two percent of participants (n = 27) reported some service disruption (e.g., full closure, substantial reduction in provision, and/or pausing of in person appointments). Waiting times for assessment had become longer for 58% of services (n = 30), due to pandemic-related disruption. Six themes emerged from thematic analysis of open responses: (1) the autism diagnostic pathway, pre-pandemic; (2) initial impact of the pandemic on service delivery; (3) conducting autism assessments during the pandemic; (4) working remotely; (5) improving service design and delivery; and (6) post-diagnostic support. Views about the accessibility, validity, and reliability of conducting telehealth autism assessments were polarized. Some participants considered this efficient, flexible, and adequate; others viewed this as unethical and inappropriate. What constitutes good practice in telehealth autism assessments remains unclear, but there is a general openness to using this method (potentially in a hybrid telehealth-in person model), provided rigor and standardization are enhanced. Conclusions: The pandemic has potentially compounded existing bottlenecks to the autism diagnostic pathway. Future research should seek to improve timeliness, standardization, accessibility and robustness of this pathway, and the validity and reliability of telehealth autism assessments.

COVID-19 and Perceived Changes to Quality of Life, Anxiety, Depression, and Loneliness in Autistic and Other Neurodivergent U.K. Adults.

Background: In the United Kingdom, we have experienced many changes to our daily lives as a result of COVID-19. Autistic and other neurodivergent (ND, e.g., those with attention-deficit hyperactivity disorder) adults may be more vulnerable to negative effects of the pandemic due to pre-existing mental health disparities and unmet support needs. Furthermore, there is little research, either pandemic related or otherwise, which considers how the experiences of autistic adults with additional intersecting ND identities might differ from those without. Methods: We collected data from an online survey during June 2020 to September 2020 to explore the psychological impact of the coronavirus pandemic on U.K. adults (N = 286, age 18-72 years). Participants included neurotypical (NT) adults (N = 98), autistic adults (N = 73), other ND adults (N = 53), as well as autistic adults with an additional intersecting ND identity (N = 63). We measured and compared levels of quality of life (QoL), depression, anxiety, and loneliness across groups as well as perceived change in these as a result of the pandemic. Results: Autistic adults, with and without additional ND identities, had consistently low QoL and high anxiety, depression, and loneliness compared with NT adults. We found no differences in these areas between autistic adults with and without additional intersecting ND identities. In some areas, non-autistic ND participants were also doing poorly compared with their NT peers. Many participants felt that their QoL, mental health, and loneliness had worsened due to the pandemic, and this was largely similar across groups. Conclusions: These results highlight that COVID-19 may have led to increased need and demand for mental health services across the U.K. adult population. Both autistic and ND adults may be in particular need of increased (and improved) mental health and well-being support. This is likely because of pre-existing differences in mental health and well-being as well as individuals facing further difficulties as a result of the pandemic.

Why is this an important issue? The coronavirus pandemic has been difficult for many people. Some researchers have found that the pandemic may have been especially difficult for autistic adults and those who are neurodivergent in another way. This might be because autistic and neurodivergent people often experience poor mental health and have a variety of unmet needs. What was the purpose of this study? The purpose of this study was to explore quality of life, depression, anxiety, and loneliness in different groups of adults during the pandemic. We also wanted to explore whether people felt that these had become worse during the pandemic. We were interested to explore differences between autistic adults and other groups of neurodivergent adults. This included autistic adults, autistic adults who were neurodivergent in another way, non-autistic neurodivergent adults, and a comparison group of adults who were not autistic or neurodivergent in any way. What did the researchers do? We recruited participants to take part in an online survey during June 2020 to September 2020. We advertised the study using social media and research websites. A total of 286 adults from the United Kingdom completed our survey. What were the results of the study? Autistic adults had consistently low quality of life and high anxiety, depression, and loneliness compared with the comparison group. This was the same regardless of whether the autistic adults were neurodivergent in another way too. In some areas, non-autistic neurodivergent participants had lower quality of life than the comparison group. Their depression and loneliness scores were somewhere in between autistic participants' and the comparison group's. Many participants felt that their quality of life, mental health, and loneliness had worsened due to the pandemic. This was similar for participants in all the groups. However, there were also participants who felt much better due to coronavirus restrictions. What do these findings add to what was already known? We now know that autistic adults have experienced poor quality of life, mental health, and loneliness during the pandemic. We also found that there were no differences based on whether autistic adults were also neurodivergent in another way (e.g., an autistic adult with attention-deficit hyperactivity disorder). We also know that non-autistic neurodivergent adults have experienced low quality of life during this time. This is important because there has been very little research on other non-autistic neurodivergent adults' experiences during COVID-19 restrictions. What are potential weaknesses in the study? Most of our participants were white British and female. This means that our findings may not be relevant to all adults in the United Kingdom. Our study was carried out during the pandemic, which means that we do not know if these differences between the groups will continue to be true in the future. How will these findings help autistic adults now or in the future? We hope that these findings will help to argue for more support to be made available to promote good quality of life and reduce mental health difficulties for autistic, and other neurodivergent, adults. Lots of our participants felt that their quality of life and mental health had got worse due to the pandemic. Because of this, it is now even more important that governments make changes to policy and funding to provide better services and support for autistic and neurodivergent adults.

Autism Spectrum Disorder and Mental Health Problems: Patterns of Difficulties and Longitudinal Trajectories in a Population-Based Twin Sample.

There is increasing concern regarding additional psychiatric problems that co-occur with Autism Spectrum Disorder (ASD), as reflected in recent changes to diagnostic schemes. However, there remains little research with population-based samples across childhood. We report on additional problems, as measured by the Strengths and Difficulties Questionnaire, in a population-based sample of 135 twins with ASD, 55 non-ASD co-twins, and 144 comparison twins low in ASD traits. Frequencies, associated demographic factors, and changes in mental health difficulties from age 4 to 13 years are presented. Our data confirm the high rates of additional difficulties reported in previous studies, and suggest that the profile, associated risk factors and longitudinal course of additional difficulties in ASD may differ from those in typically-developing populations.

Quality of life, functional impairment and continuous performance task event-related potentials (ERPs) in young adults with ADHD and autism: A twin study.

Background: Young adulthood is a key developmental period for understanding outcomes of childhood onset attention-deficit/hyperactivity disorder (ADHD) and autism. Measurement of functional impairment and quality of life (QoL) can provide important information on the real-life challenges associated with these conditions. Event-related potential (ERP) measures from the continuous performance task (CPT) have long been identified as altered in ADHD and autism but the role of these functions in the aetiological pathway to the disorders and associated impact on quality of life in young adulthood is unknown. Method: We investigated the relationships between ADHD and autism, functional impairment, quality of life, and ERP measures from the cued CPT (CPT-OX) in a young adult twin sample (566 participants aged 22.43 ± 0.96 years old). Results: We observed significant phenotypic correlations between ADHD/autism and lower quality of life with specific genetic overlap between ADHD and physical health, psychological, and environmental aspects. We found significant phenotypic and genetic correlations between ADHD and functional impairment in all domains, as well as between autism and impairment in social functioning and lower impairment in risk-taking. Both ADHD and autism were associated with attenuated amplitude of inhibitory and proactive control ERPs, with large genetic contributions to the overlap. We also found significant phenotypic correlations between these ERP measures and Weiss Functional Impairment Rating Scale (WFIRS) and QoL. Conclusion: This is the first study to investigate the phenotypic and genetic relationships between ADHD and autism, functional impairment, quality of life and ERP measures in young adulthood. Our findings could represent a step towards identifying ERP measures that are related to behaviour in the absence of overt symptoms.

A Meta-analysis of Outcome Studies of Autistic Adults: Quantifying Effect Size, Quality, and Meta-regression.

Longitudinal studies have generally reported poor outcomes in adulthood for the majority of individuals (c.50-60%) with autism. Several factors putatively predict outcome (e.g. IQ), but findings remain mixed. This paper presents an updated meta-analysis of autism outcome studies and extends previous findings with additional analyses (including meta-regression). A total of 4088 records was screened and 18 studies, involving 1199 individuals, were included in the quantitative analysis. Estimated percentages indicated that 20.0% of participants were rated as having a good outcome, 26.6% a fair outcome, and 49.3% a poor outcome. Meta-regression indicated that lower IQ in adulthood was predictive of poor outcome; other meta-regression models did not survive correction for multiple comparisons. Overall, outcomes for autistic people are on average poor, and higher IQ appears to be protective against having a poor outcome. The limitations of current constructs of outcome are discussed.
