Boys with Asperger Syndrome Grow Up: Psychiatric and Neurodevelopmental Disorders 20 Years After Initial Diagnosis

Association Between Autism and PTSD Among Adult Psychiatric Outpatients

PURPOSE

Autism Spectrum Disorder (ASD) occurs in 1-1.5% of the general population and possibly in up to 20% of psychiatric outpatients. Post Traumatic Stress Disorder (PTSD) occurs at some point in life in 4% of the general population and in 14-20% of psychiatric outpatients. Knowledge about how PTSD manifests in people with ASD is important in order for it to be correctly diagnosed and intervened for.

METHODS

This study investigated the relationship between PTSD and autism among adult psychiatric outpatients (N = 90) of whom 63 had ASD or subthreshold ASD based on DSM-5 criteria. The study group was subjected to in-depth psychiatric assessments using validated instruments. Diagnosis of PTSD was made based on the Mini International Neuropsychiatric Interview (MINI).

RESULTS

There was a trend towards PTSD being more common among participants with ASD compared to participants without ASD, although significant differences could not be shown in this small sample. 21% of the ASD group had current PTSD, compared to 4% of the study group without ASD. There were no differences between the groups regarding exposure to trauma. There was a trend towards a relationship between number of autism symptoms and hyperarousal symptoms in PTSD. Conversely, the PTSD symptom of irritability/outbursts of anger, was significantly associated with number of autism symptoms.

CONCLUSIONS

A subgroup of psychiatric outpatients with ASD also suffer from PTSD. Hyperarousal symptoms are possibly more prevalent in the presentation of PTSD in individuals/patients with ASD compared to those without ASD.

The Autism Constellation and Neurodiversity: Long-Term and Adult Outcomes in Autism Spectrum Disorder

Research on autistic adults suggests significant heterogeneity in outcomes. A significant proportion of individuals struggle with intellectual disability and limited communication skills. Of the 67% who have age-appropriate cognitive skills, around half are expected to attain a college education, and 25% are likely to hold a full-time job. Outcomes have been improving over time, in part because of earlier diagnosis and earlier intervention. Indeed, an estimated 10% to 20% are expected to lose all symptoms of autism by adolescence.

Cross-cultural variation in experiences of acceptance, camouflaging and mental health difficulties in autism: A registered report

Recent findings suggest that stigma and camouflaging contribute to mental health difficulties for autistic individuals, however, this evidence is largely based on UK samples. While studies have shown cross-cultural differences in levels of autism-related stigma, it is unclear whether camouflaging and mental health difficulties vary across cultures. Hence, the current study had two aims: (1) to determine whether significant relationships between autism acceptance, camouflaging, and mental health difficulties replicate in a cross-cultural sample of autistic adults, and (2) to compare these variables across cultures. To fulfil these aims, 306 autistic adults from eight countries (Australia, Belgium, Canada, Japan, New Zealand, South Africa, the United Kingdom, and the United States) completed a series of online questionnaires. We found that external acceptance and personal acceptance were associated with lower levels of depression but not camouflaging or stress. Higher camouflaging was associated with elevated levels of depression, anxiety, and stress. Significant differences were found across countries in external acceptance, personal acceptance, depression, anxiety, and stress, even after controlling for relevant covariates. Levels of camouflaging also differed across countries however this effect became non-significant after controlling for the covariates. These findings have significant implications, identifying priority regions for anti-stigma interventions, and highlighting countries where greater support for mental health difficulties is needed.

Beyond Diagnosis: Preliminary Study of Impact on Children and Parents in Neurodevelopmental Disorders and Juvenile Idiopathic Arthritis-Associated Uveitis

Chronic diseases are a growing problem for global health due to the large number of people they involve, the repercussions they have on the mental and physical well-being of those affected, and the costs to society. Particularly, chronic illnesses of childhood have important psychological implications, not only for affected children but also for their parents. Among these pathologies, neurodevelopmental disorders (NDDs) and uveitis associated with juvenile idiopathic arthritis (JIA-U) may affect mental and physical health, emotions, memory, learning, and socializing. This study evaluates the psychological and behavioral/emotional impact of NDDs and JIA-U on children and parents. Specifically, 30 children with active JIA-U and 30 children with NDDs and their parents completed the Child Behavior Checklist (CBCL) and Parent Stress Index-Short Form (PSI) questionnaires. Children with NDDs have statistically significant differences in all the emotional and behavioral variables compared to JIA-U children, and parents of children with NDDs experience an increased stress load compared to parents of children with JIA-U. This study emphasizes the wide range of emotional and behavioral challenges that parents face with NDDs. This study emphasizes that parents of children with NDDs not only experience higher levels of stress compared to parents of normally developing children but also experience higher levels of stress compared to parents of children with potentially debilitating chronic diseases such as JIA-U.

An internet-based behavioral intervention for adults with autism spectrum disorder - A randomized controlled trial and feasibility study

Background

The increased prevalence of Autism Spectrum Disorder (ASD) diagnoses in combination with psychiatric comorbidity, has led to an increased need for effective interventions. The evidence for internet-based interventions for several mental health problems is established but has not been evaluated for adults with ASD.

Objective

The aim of this randomized controlled trial is to evaluate the feasibility and effects of an internet-based intervention targeting quality of life and psychiatric symptoms (depression and anxiety) in adults with ASD.

Methods

84 participants were randomly allocated to intervention (n = 42) or control (n = 42). The 18-week internet-based intervention covered a range of themes related to difficulties common in ASD, and exercises based on cognitive behavioral strategies. Participants were provided with individual feedback following each module and were invited to regular chat sessions with peer participants. The primary outcomes were subjective quality of life and sense of coherence, and secondary outcomes were symptoms of depression and anxiety. All outcomes were measured at five occasions and analysed with linear mixed effect models. Participant satisfaction and adherence was also analysed.

Results

Participant satisfaction and adherence was satisfactory but no significant interaction between group and time was found for any outcome measure. Autistic traits were negatively related to quality of life and sense of coherence and positively related to anxiety and depressive symptoms.

Conclusions

This internet-based intervention showed feasibility regarding adherence and participant satisfaction. However, no significant effects on quality of life, sense of coherence or psychiatric symptoms were found, likely due to limitations in the design and methodology of this specific trial in combination to the heterogeneity of the group. Individuals with ASD may require interventions that are flexible and individually tailored in regard to both format, content and therapeutic support. The current trial provides useful information and suggestions for the future research on internet-based interventions for ASD.

Facilitators and barriers in psychotherapy from the perspective of autistic adults: an enhanced critical incident study

PURPOSE

A significant portion of autistic adults experience mental health challenges. Currently, the literature is incomplete when it comes to understanding the needs and preferences of autistic adults who receive therapy. This study elicited the perspectives of autistic adults, focusing on the facilitators, barriers and ways to enhance psychotherapy based on receiving this care for mental health problems.

METHODS

Using the qualitative, exploratory approach of the Enhanced Critical Incident Technique, eight autistic adults took part in interviews.

RESULTS

A total of 147 critical incidents were extracted from participant interviews and categories salient to therapeutic practice. The study identified key factors influencing therapy, such as trust and respect, practical approaches, client factors, structure of sessions, knowledge about autism, support for individualized needs, access to mental health services, and involvement of family/advocate. These factors were categorized into eight main areas relevant to therapeutic practice.

CONCLUSIONS

Findings from this research reveal that psychotherapy with autistic adults is analogous to performing this work with non-autistic adults, in the sense that this work too entails elements of individually tailored treatment and the reliance on common therapeutic factors. There are also differences in this work that necessitate providers having foundational knowledge about autism. Learning directly from autistic adults' insights may help to improve upon the delivery of mental health care for autistic adults.

Prevalence of co-occurring conditions in children and adults with autism spectrum disorder: A systematic review and meta-analysis

This systematic review estimates the prevalence of co-occurring conditions (CCs) in children and adults with autism. A comprehensive search strategy consulting existing guidelines, diagnostic manuals, experts, carers, and autistic people was developed. PubMed and PsycInfo databases from inception to May 2022 were searched. PROSPERO registration: CRD42019132347. Two blind authors screened and extracted the data. Prevalence estimates for different CCs were summarized by using random effects models. Subgroup analyses were performed for age groups (children/adolescents vs adults) and study designs (population/registry-based vs clinical sample-based). Of 19,932 studies, 340 publications with about 590,000 participants were included and meta-analyzed to estimate the prevalence of 38-point prevalence, 27-lifetime, and 3 without distinction between point and lifetime prevalence. Point prevalence of developmental coordination disorder, sleep-wake problem, gastrointestinal problem, ADHD, anxiety disorder, overweight/obesity, feeding and eating disorder, elimination disorder, disruptive behavior, and somatic symptoms and related disorder were the most frequent CCs. Prevalence differed depending on the age group and study design. Knowing specific CCs linked to autism helps professional investigations and interventions for improved outcomes.

Mental Health Providers' Perspectives on What Helps and Hinders in Psychotherapy for Autistic Adults with Co-occurring Mental Health Problems

Autistic adults experience disproportionate rates of co-occurring mental health problems. Psychotherapy has been recognized as an appropriate treatment approach, but evidence is limited. Researchers used a qualitative research paradigm to explore the experiences of mental health providers who provide psychotherapy to autistic adults. The Enhanced Critical Incident Technique was used to interview 13 mental health providers regarding perceptions of facilitating therapy with autistic adults. This research highlights challenges to providing psychotherapy to autistic adults while also illuminating ways that mental health providers have worked to ameliorate such challenges and create positive experiences in therapy. This research also contrasts therapy for autistic adults relative to the general population. Practice recommendations and suggestions for future research are offered.

Autism in adult psychiatric out-patients: self-reported suicidal ideation, suicide attempts and non-suicidal self-injury

BACKGROUND

The prevalence of self-reported suicidal ideation, suicide attempts and non-suicidal self-injury (NSSI) remains unclear among adults with autism unrecognised in childhood who attend psychiatric services.

AIMS

We aimed to estimate the prevalence of suicidal ideation, suicide attempts and NSSI; identify factors associated with suicide attempts and NSSI; and describe NSSI in this group.

METHOD

Sixty-three new patients at an adult psychiatric out-patient clinic (57% women, mean age 32 years) who met full (n = 52) or subthreshold (two A criteria and minimum of two B criteria; n = 11) DSM-5 criteria for autism spectrum disorder were included in the study. Clinical assessments included overall diagnostic review, Paykel's questions on passive and active suicidality, evaluation of NSSI with the Functional Assessment of Self-Mutilation, and results of cognitive tests. One follow-up of medical records was made.

RESULTS

In this sample of psychiatric out-patients identified as first having autism in adulthood, almost a third (31%) of patients reported suicidal ideation during the past month, 86% had lifetime suicidal ideation and 25% reported at least one suicide attempt. Factors associated with suicide attempts included hazardous or harmful alcohol use and/or drug-related problems, and severity of depression. A total of 44% reported NSSI. Factors associated with NSSI were female sex, history of suicidal plans and antisocial personality disorder. Substance or alcohol use were often overlooked, especially in women.

CONCLUSIONS

Suicidal ideation, suicide attempts and NSSI were very common in adults with autism who were recently referred to an out-patient psychiatric service. Suicidal ideation and NSSI were more common than suicide attempts. Clinicians should always consider suicidal ideation and NSSI in adult psychiatric patients with autism.

Applications of identity-based theories to understand the impact of stigma and camouflaging on mental health outcomes for autistic people

Autistic people have long been conceptualized from a deficit-based model of disability, but recent self-advocates and scholars have asserted the importance of recognizing autism as both a disability and an important part of a person's social identity. The autistic identity is subject to specific stigma and stressors beyond everyday discrimination and prejudice, which can have many downstream implications on mental health and well-being. Prior research on camouflaging has explained both quantitatively and qualitatively how autistic people conform to norms and mask their autistic traits to better fit in with non-autistic societal standards. Given this paradigm shift in understanding autistic peoples' lived experiences, researchers must also begin to reshape the theories guiding their work in order to improve diagnosis, intervention, and supports. This review examines the extant research on identity-related stigma and camouflaging and their subsequent impacts on mental health outcomes in autism. A model is proposed integrating identity-based theories-specifically the social model of disability, social identity theory, and minority stress model-to explain relationships across research areas and better explain the experiences of autistic people. We discuss how identity-based theories can be applied in autism research to better understand the impacts of stigma and camouflaging on autistic peoples' lived experiences and reduce disparities in their mental health outcomes.

Brain white matter microstructure abnormalities in children with optimal outcome from autism: a four-year follow-up study

Autism spectrum disorder (ASD) is a lifelong neurodevelopmental disorder, with only a small proportion of people obtaining optimal outcomes. We do not know if children with ASD exhibit abnormalities in the white matter (WM) microstructure or if this pattern would predict ASD prognosis in a longitudinal study. 182 children with ASD were recruited for MRI and clinical assessment; 111 completed a four-year follow-up visit (30 with optimal outcomes, ASD-; 81 with persistent diagnosis, ASD+). Additionally, 72 typically developing controls (TDC) were recruited. The microstructural integrity of WM fiber tracts was revealed using tract-based spatial statistics (TBSS) and probabilistic tractography analyses. We examined the neuroimaging abnormality associated with ASD and its relationship to ASD with optimal outcome. The ASD+ and TDC groups were propensity score matched to the ASD- group in terms of age, gender, and IQ. TBSS indicated that children with ASD exhibited abnormalities in the superior longitudinal fasciculus (SLF), inferior longitudinal fasciculus (ILF), and extending to the anterior thalamic radiation (ATR) and cingulum; whereas the ASD+ group showed more severe abnormalities than the ASD- group. Probabilistic tractography analysis revealed that ASD+ group exhibited lower Fractional Anisotropy (FA) of the left superior thalamic radiation (STR L) than ASD- group, and that FA value of the STR L was a significant predictor of optimal outcome (EX(B), 6.25; 95% CI 2.50-15.63; p < 0.001). Children with ASD showed significant variations in SLF_L and STR_L, and STR_L was a predictor of 'ASD with optimal outcome'. Our findings may aid in comprehension of the mechanisms of 'ASD with optimal outcome'.

Adaptive behavior and psychiatric symptoms in university students with ASD: One-year longitudinal study

In recent years, more young adults with ASD are attending post-secondary education, and several support programs have been proposed for this population. However, research regarding the long-term effects of university enrollment on outcomes among students with ASD is scarce. This study examined adaptive behavior and psychiatric symptoms during the first semester of two consecutive academic years (T1, T2) among 39 students with ASD, 29 students without ASD and high levels of social anxiety symptoms (High SA), and 32 students without ASD and low levels of SA symptoms (Low SA). Students with ASD participated in a university support program and resided with a peer mentor student without ASD, which encouraged social interaction. At T1, students with ASD reported lower levels of adaptive behavior and higher levels of social anxiety and obsessive-compulsive symptoms compared to the other groups. However, at follow-up (T2), significantly higher conceptual adaptive skill levels (specifically communication skills) and significantly lower depression symptom levels from T1 were reported only among students with ASD. The levels of social anxiety and obsessive-compulsive symptoms at T1 were negatively associated with adaptive functioning a year later (T2). Implications regarding adults with ASD attending university are discussed.

Adapting Drug and Alcohol Therapies for Autistic Adults

Background

Autistic people may be at a higher risk of drug and alcohol misuse than the general population. Autistic people, however, are under-represented within drug and alcohol support services. This is the first survey of drug and alcohol therapists' perceptions of current service provision for autistic clients and recommendations for reasonable adjustments that therapists can make to enhance successful outcomes.

Methods

We conducted an online survey of 122 drug and alcohol therapists, exploring therapists' demographics, training and experience with autistic clients, approaches and adaptations used with autistic clients, and therapists' confidence with autistic clients. Within two focus groups, 11 members of the autistic and broader autism (e.g., family members, professionals) communities reflected on the reasonable adjustments reported by therapists.

Results

Most therapists had autistic clients and most therapists had received no autism-specific training. Alcohol misuse was the most common presenting issue, and most therapists reported that treatment outcomes were less favorable for autistic clients than for other groups. Therapists perceived that barriers to successful outcomes were (1) a lack of autism-specific training, (2) a need to adapt therapy for autistic clients, and (3) a lack of shared perspective between the therapist and the autistic client. Previous research has identified a range of reasonable adaptations and, when asked, therapists were moderately confident in their ability to deliver these. Members of the autistic and broader autism communities coproduced guidance detailing how therapists can best adapt their practice for autistic clients including how to structure sessions and the language to use within sessions.

Conclusion

This study highlights a need for practical and theoretical training for drug and alcohol therapists to support successful adaptation to current service provision for autistic clients and to develop a shared perspective on the desired aims and outcomes of the therapeutic process.

Neurodevelopmental disorders and comorbidity in young adults attending a psychiatric outpatient clinic

"Missed" cases with neurodevelopmental disorders (NDDs) within adult psychiatry services have attracted increasing attention in the last decade. Key questions have been what the prevalence of NDDs (particularly attention-deficit/hyperactivity disorder/ADHD and autism spectrum disorder/ASD) is, and what the clinical and gender characteristics of those with NDD in adult psychiatry are. All first-time attenders at an adult psychiatry clinic serving 18-25 years old were invited to take part in the study regardless of cause of concern. Participation in the study included diagnostic in-depth evaluation performed by experienced adult psychiatrists. Clinical diagnoses (DSM-IV-TR and DSM-5 criteria) were based on all available information (clinical psychiatric interview, clinical observation, and self-rating questionnaires). Almost two thirds (63%) of the study group met criteria for ADHD or ASD. Most of the patients with NDD (particularly the "NDD females") had not been diagnosed in childhood. Twelve percent of the females included had been given an ADHD diagnosis in childhood. In the current study we found that 48% of the females had ADHD. The high male:female NDD ratio reported among children, was not obvious in our NDD group. The results underscore the importance of screening for NDD in adult psychiatric services regardless of referral reason.

Prevalence of Autism Spectrum Disorders in Adult Outpatient Psychiatry

Relatively little has been published about the prevalence of autism in adults with psychiatric disorders. In this study, all new patients referred to an adult psychiatric outpatient clinic in Sweden between November 2019 and October 2020 (n = 562) were screened for autism spectrum disorders using the Ritvo Autism and Asperger Diagnostic Scale Screen (RAADS-14). Out of the 304 (58%) responders, 197 who scored above the cut off (14) were invited to participate in an in-depth assessment. Twenty-six of the 48 that participated in the assessment met criteria for ASD and an additional eight had subthreshold ASD symptoms. We estimated the prevalence of ASD in this population to at least 18.9%, with another 5-10% having subthreshold symptoms.

An Internet Based Intervention for Adults With Autism Spectrum Disorder-A Qualitative Study of Participants Experiences

Background: Adults with autism spectrum disorder face several barriers to accessing evidence-based care, including difficulties in communicating needs, social anxiety or in traveling to a health care unit. In recent years, several forms of internet-based treatments have shown to be effective for a variety of psychiatric conditions. Internet-based treatment alternatives allow convenient and flexible formats, and therefore have the potential to increase access to health care for individuals with autism spectrum disorder. However, knowledge about how internet-based treatment features may suit the needs of individuals with autism is limited. The aim of this study was to explore the participant experiences of an internet-based intervention for adults with autism spectrum disorder. The primary focus of the investigation was on autism-specific needs in relation to the features unique to the online format. Methods: In this qualitative study, semi-structured telephone interviews were conducted with 14 participants who had completed a text-based internet-based intervention for adults with autism spectrum disorder. We used an inductive approach and analyzed the data using qualitative content analysis. Results: Five main categories were identified: (1) implications of the online format, (2) the fixed non-individualized model, (3) therapist interaction, (4) interacting with other participants, and (5) making use of the treatment content. Overall, participants appreciated the availability and that they could work on their treatment independent of time or location. Among those participating in group-based chat-sessions with the other participants, it was considered a generally positive experience. Furthermore, most participants felt safe and relaxed in relation to the therapist and appreciated the text-based format. However, several participants felt that the format and content of the treatment was not sufficiently adapted to their individual life situation. Conclusion: In conclusion, this internet-based treatment constitutes an accessible and energy-saving treatment alternative for adults with autism. Further, integrating group-based components seems feasible in an otherwise individual internet-based treatment for individuals with autism. However, group-based components do require a clear purpose and rationale. Future studies should develop and evaluate treatment adaptations tailored to individual needs.

Adults with Autism: Changes in Understanding Since DSM-111

Over the past four decades there have been significant advances in our understanding of autism, yet services for autistic adults continue to lag far behind those for children, and prospects for employment and independent living remain poor. Adult outcomes also vary widely and while cognitive and language abilities are important prognostic indicators, the influence of social, emotional, familial and many other factors remains uncertain. For this special issue marking the 40th anniversary of DSM-III, the present paper describes the changing perspectives of autism in adulthood that have occurred over this period, explores individual and wider environmental factors related to outcome, and suggests ways in which services need to be changed to improve the future for adults living with autism.

Autistic Adult Health and Professional Perceptions of It: Evidence From the ASDEU Project

The Autism Spectrum Disorders in the European Union (ASDEU) survey investigated the knowledge and health service experiences of users and providers to generate new hypotheses and scientific investigations that would contribute to improvement in health care for autistic adults. An online survey designed for autistic adults, carers of autistic adults, and professionals in adult services was translated into 11 languages and distributed electronically by organizations and in-country adult service facilities in 2017; 522 autistic adults, 442 carers, and 113 professionals provided answers to the health questions. Professionals, the majority in non-medical services, appeared to be poorly informed about whether certain co-occurring conditions were more frequent in autistic adults than typical adults-especially some medical conditions, suicide attempts, accidents, and pain. A minority of autistic adults reported preventive health behaviors such as routine health check-ups. The majority of users and providers expressed the desire to make health care services more user-friendly for autistic adults. Among the three groups, <20% of responders knew an organization or clinician which has developed a way to monitor health, and prevent poor health, that works well for adults on the autism spectrum. The results point to means for better management of co-occurring conditions associated with autism in adulthood in order to reduce hospital admissions and potential areas of improvement in health and social services for autistic adults. Specifically, efforts should be focused on (1) professionals' education on risks for co-occurring conditions in autistic adults; (2) promoting preventive health behaviors; (3) making services user-friendly for autistic adults and their families; and (4) encouraging knowledge of good local services.

Low prevalence of risk drinking in adolescents and young adults with autism spectrum problems

Individuals with Autism Spectrum Disorder (ASD) have high rates of "comorbidity". Research on concurrent substance use (disorder) in ASD, however, is scarce and findings have been inconsistent. This study aims at assessing the prevalence of risk drinking in adolescent and young adult twins with and without autism spectrum problems. Data from a Swedish longitudinal nationwide twin study were analyzed. Across three age groups of 15- (N = 10,050), 18- (N = 7,931) and 24-year-olds (N = 2,882) prevalence rates of risk drinking were compared between twins with and without an ASD proxy diagnosis and between different ASD subgroups based on comorbid proxies for attention-deficit/hyperactivity disorder (ADHD) and/or Learning Disorder (LD). ASD, ADHD, and LD were assessed using the Autism-Tics, ADHD, and other Comorbidities inventory (A-TAC), and risk drinking was captured by the Alcohol Use Disorders Identification Test (AUDIT; age 18 and 24) and another set of self-report questions (age 15). In each age group, the prevalence of risk drinking in ASD was lower than in individuals without ASD, yet increasing continuously with age. Exploratory subgroup ASD analyses showed a trend towards risk drinking being more common among individuals with co-existing ADHD or LD problems than among those without "comorbidity", although sample sizes were too small to draw any certain conclusions. This study indicates low prevalence of risk drinking in adolescents and young adults with autism spectrum problems and highlights the need for further research on alcohol use in individuals with ASD and comorbid disorders.

The Role of Diagnostic Instruments in Dual and Differential Diagnosis in Autism Spectrum Disorder Across the Lifespan

The heterogeneity inherent in autism spectrum disorder (ASD) makes the identification and diagnosis of ASD complex. We survey a large number of diagnostic tools, including screeners and tools designed for in-depth assessment. We also discuss the challenges presented by overlapping symptomatology between ASD and other disorders and the need to determine whether a diagnosis of ASD or another diagnosis best explains the individual's symptoms. We conclude with a call to action for the next steps necessary for meeting the diagnostic challenges presented here to improve the diagnostic process and to help understand each individual's particular ASD profile.

Evaluating specialist autism teams’ provision of care and support for autistic adults without learning disabilities: the SHAPE mixed-methods study

Background

The National Institute for Health and Care Excellence recommends that every locality has a ‘Specialist Autism Team’: an specialist autism, community-based, multidisciplinary service that is responsible for developing, co-ordinating and delivering care and support. The National Institute for Health and Care Excellence recommended that this novel delivery model was evaluated.

Objectives

The objectives were to identify services fulfilling the National Institute for Health and Care Excellence’s description of a Specialist Autism Team; to describe practitioner and user experiences; to investigate outcomes; to identify factors associated with these outcomes; and to estimate costs and investigate cost-effectiveness of these services.

Design

During stage 1, desk-based research and a survey to identify Specialist Autism Teams were carried out. Stage 2 comprised a mixed-methods observational study of a cohort of Specialist Autism Team users, which was followed for up to 2 years from the assessment appointment. The cohort comprised users of a Specialist Autism Team not previously diagnosed with autism (the ‘Diagnosis and Support’ group) and those already diagnosed (the ‘Support-Only’ group). Stage 2 also involved a nested qualitative study of senior practitioners and an exploratory comparison of the Diagnosis and Support group with a cohort who accessed a service which only provided autism diagnostic assessments (‘Diagnosis-Only’ cohort).

Setting

The setting in stage 2 was nine Specialist Autism Teams; three also provided a regional diagnostic assessment service (used to recruit the Diagnosis-Only cohort).

Participants

There were 252 participants in the Specialist Autism Team cohort (Diagnosis and Support, n = 164; Support Only, n = 88) and 56 participants in the Diagnosis-Only cohort. Thirty-eight participants (across both cohorts) were recruited to the qualitative evaluation and 11 practitioners to the nested qualitative study.

Main outcome measures

The World Health Organization Quality of Life assessment, abbreviated version (psychological domain) and the General Health Questionnaire (12-item version).

Data sources

Self-reported outcomes, qualitative interviews with users and focus groups with practitioners.

Results

A total of 18 Specialist Autism Teams were identified, all for autistic adults without learning disabilities. Services varied in their characteristics. The resources available, commissioner specifications and clinical opinion determined service design. Practitioners working in Specialist Autism Teams recruited to stage 2 reported year-on-year increases in referral rates without commensurate increases in funding. They called for an expansion of Specialist Autism Teams’ consultation/supervision function and resources for low-intensity, ongoing support. For the Specialist Autism Team cohort, there was evidence of prevention of deterioration in outcomes and positive benefit for the Diagnosis and Support group at the 1-year follow-up (T3). Users of services with more professions involved were likely to experience better outcomes; however, such services may not be considered cost-effective. Some service characteristics were not associated with outcomes, suggesting that different structural/organisational models are acceptable. Findings suggest that one-to-one work for mental health problems was cost-effective and an episodic approach to delivering care plans was more cost-effective than managed care. Qualitative findings generally align with quantitative findings; however, users consistently connected a managed-care approach to supporting improvement in outcomes. Among the Diagnosis-Only cohort, no changes in mental health outcomes at T3 were observed. Findings from the interviews with individuals in the Diagnosis and Support group and Diagnosis-Only cohort suggest that extended psychoeducation post diagnosis has an impact on immediate and longer-term adjustment.

Limitations

Sample size prohibited an investigation of the associations between some service characteristics and outcomes. Comparison of the Diagnosis-Only cohort and the Diagnosis and Support group was underpowered. The economic evaluation was limited by incomplete costs data.

Conclusions

The study provides first evidence on the implementation of Specialist Autism Teams. There is some evidence of benefit for this model of care. Service characteristics that may affect outcomes, costs and cost-effectiveness were identified. Finding suggest that extended psychoeducation post diagnosis is a critical element of Specialist Autism Team provision.

Future work

We recommend a comparative evaluation of Specialist Autism Teams with diagnosis-only provision, and an evaluation of models of providing consultation/supervision and low-intensity support.

Funding

This project was funded by the National Institute for Health Research (NIHR) Health Services and Delivery Research programme and will be published in full in Health Services and Delivery Research; Vol. 8, No. 48. See the NIHR Journals Library website for further project information.

The Expectancies and Motivations for Heavy Episodic Drinking of Alcohol in Autistic Adults

Background

For autistic adults, the perceived benefits of drinking alcohol to facilitate social interaction may be particularly appealing. Alcohol may be considered "self-medication" for clinical features of autism or may be used to help cope with elevated levels of co-occurring anxiety.

Methods

We developed an online survey and 507 autistic adults responded to questions concerning their expectancies and motivations for heavy episodic drinking. The survey also included questions about ways of seeking support, if needed, and barriers to seeking support.

Results

Over half of those who had drunk alcohol reported heavy episodic drinking in the past year (6 or more units of alcohol at one time). Heavy episodic drinkers endorsed traditional expectancies (e.g., "Alcohol generally has powerful positive effects on people") and autism-specific expectancies (e.g., "Alcohol makes verbal communication easier") to a greater degree than nonheavy episodic drinkers. Autism-specific expectancies, not traditional expectancies, related to frequency of drinking. The strongest motivations for heavy episodic drinking were for social reasons and to enhance positive feelings, rather than for conformity or coping. If support was required for problematic drinking, the internet was the most commonly chosen resource, although 45% of the participants indicated that they would not seek support. Perceived barriers to support included concern that it would take place in an unfamiliar chaotic environment and concern about being misunderstood and judged by a therapist.

Conclusions

This study is the first to identify the expectancies and motivations for heavy episodic drinking in autistic adults as well as identifying barriers to seeking support. There may be some autism-specific expectancies related to the nature of autism that impact upon heavy episodic drinking, as well as impacting upon seeking support. The autistic and broader autism communities can benefit from an awareness of these findings, and service providers can adapt support appropriately.

Lay summary

Why was this study done?: Little is known about how alcohol is used within the autistic community. One population-based study found that autistic adults were four times more likely to experience problematic drinking compared with nonautistic adults.What was the purpose of this study?: This study identified the expectations and motivations for heavy episodic-or "binge"-drinking alcohol among autistic adults. Binge drinking is a risk factor for problematic drinking. The study also identified how autistic adults accessed support should it be needed, and what the potential barriers were to accessing support.What did the researchers do?: We conducted an online survey with 507 autistic adults with formal or informal diagnoses of autism. The survey asked about the frequency of drinking alcohol and binge drinking. Participants then answered a questionnaire about why they drank alcohol. The questions asked about general reasons for drinking (such as: "Alcohol generally has powerful positive effects on people [e.g., makes you feel good or happy; future seems brighter]") as well as autism-related reasons (such as: "Alcohol makes verbal communication easier [e.g., starting conversations, responding to what other people say, or maintaining a normal back-and-forth conversation]"). Finally, participants answered questions about seeking help and potential barriers to help-seeking.What were the results of the study?: Binge drinkers reported a greater number of traditional and autism-relevant expectations for drinking alcohol than nonbinge drinkers. The strongest motivations for drinking alcohol were for social reasons and to enhance positive feelings, rather than coping or to conform. The internet was the most common source of support for problematic drinking (49% of participants); however, 45% of participants indicated that they would not seek any support. Perceived barriers to support were an unfamiliar chaotic environment and being misunderstood and judged by a therapist. Around one fifth of participants self-diagnosed themselves with autism, rather than having a formal diagnosis from a clinician. These two groups were very similar to each other.What do these findings add to what was already known?: This is the first study to identify the expectations and motivations for binge drinking alcohol in the autistic community.What are potential weaknesses in the study?: This was an online survey, and the diagnostic status of participants cannot be verified. Participants chose to take part in the study, and this may represent a bias as some people may not want to take part in online surveys or may not have access to the internet, or may not be part of networks that send out invitations to take part in research. In addition, the sample was largely female and well educated, which is not reflective of the autistic population as a whole.How will these findings help autistic adults now or in the future?: Better understanding the expectations and motivations for binge drinking alcohol can help inform support that is targeted at the autistic community. Alcohol support services can be better informed about how to adapt their provision for the autistic community specifically.

Factors associated with positive mental health in young adults with a neurodevelopmental disorder

BACKGROUND

Positive dimension of mental health has gained less attention in previous research on individuals with neurodevelopmenal disorders. However, knowledge on factors associated with mental well-being is crucial for planning effective interventions for this target group.

AIMS

The aim of the study was to investigate the determinants of positive mental health among young adults with neurodevelopmental disorders.

METHODS AND PROCEDURES

The study sample consisted of 171 young adults (18-35 years, mean age 25 years, SD 4.35) with a diagnosis of Autism Spectrum Disorder (ASD) or ADHD/ADD. The data were collected with questionnaires.

RESULTS

The mean score of SWEMWBS was 20.98 (n = 168, ranging 14.75-35.00, SD = 3.55). Provisions of social relationships, functional capacity and self-rated state of health associated independently with positive mental health.

CONCLUSION AND IMPLICATIONS

The level of positive mental health of study participants was relatively low compared with previous studies in other clinical settings or general populations. Promotion of social competence and social relationship should be included in rehabilitation programmes targeted at individuals with neurodevelopmental disorder. This may be beneficial in reaching also other goals set for the rehabilitation, such as increasing capacity to work or study.

Anxiety Disorders in Adults with Autism Spectrum Disorder: A Population-Based Study

Anxiety is common in children with ASD; however, the burden of specific anxiety disorders for adults with ASD is under-researched. Using the Stockholm Youth Cohort, we compared anxiety disorder diagnoses among autistic adults (n = 4049), with or without intellectual disability, and population controls (n = 217,645). We conducted additional sibling analyses. Anxiety disorders were diagnosed in 20.1% of adults with ASD compared with 8.7% of controls (RR = 2.62 [95% CI 2.47–2.79]), with greatest risk for autistic people without intellectual disability. Rates of almost all individual anxiety disorders were raised, notably obsessive–compulsive disorder and phobic anxiety disorders. Anxiety disorders were more common in full siblings and half-siblings of people with ASD. The implications of this are explored.

The Role of Diagnostic Instruments in Dual and Differential Diagnosis in Autism Spectrum Disorder Across the Lifespan

The heterogeneity inherent in autism spectrum disorder (ASD) makes the identification and diagnosis of ASD complex. We survey a large number of diagnostic tools, including screeners and tools designed for in-depth assessment. We also discuss the challenges presented by overlapping symptomatology between ASD and other disorders and the need to determine whether a diagnosis of ASD or another diagnosis best explains the individual's symptoms. We conclude with a call to action for the next steps necessary for meeting the diagnostic challenges presented here to improve the diagnostic process and to help understand each individual's particular ASD profile.

Adult Manifestation of Milder Forms of Autism Spectrum Disorder; Autistic and Non-autistic Psychopathology

We compared the presence of autistic and comorbid psychopathology and functional impairments in young adults who received a clinical diagnosis of Pervasive Developmental Disorders Not Otherwise Specified or Asperger’s Disorder during childhood to that of a referred comparison group. While the Autism Spectrum Disorder group on average scored higher on a dimensional ASD self- and other-report measure than clinical controls, the majority did not exceed the ASD cutoff according to the Autism Diagnostic Observation Schedule. Part of the individuals with an ASD diagnosis in their youth no longer show behaviors that underscribe a clinical ASD diagnosis in adulthood, but have subtle difficulties in social functioning and a vulnerability for a range of other psychiatric disorders.

Self-reported social impairments predict depressive disorder in adults with autism spectrum disorder

In adults with autism spectrum disorder, co-occurring psychiatric conditions are prevalent, and depression is one of the most common co-occurring disorders. This study examined the relationship between depression and cognitive ability, autism symptom severity, and self-reported social impairments in autism spectrum disorder. A total of 33 adults with autism spectrum disorder and 28 adults with typical development completed a standardized psychiatric interview, cognitive test, measure of clinician-rated autism symptom severity, and self-report of social impairments. Nine participants with autism spectrum disorder (27%) met the criteria for a depressive disorder (autism spectrum disorder + depressive disorder). Relatively more females with autism spectrum disorder had a co-occurring depressive disorder. The typical development group had a higher intelligence quotient than the autism spectrum disorder group, but the autism spectrum disorder + depressive disorder group did not differ from the typical development or autism spectrum disorder group. While the autism spectrum disorder + depressive disorder group had lower clinician-rated autism symptom severity than the autism spectrum disorder group, the autism spectrum disorder + depressive disorder group reported more social impairments than the autism spectrum disorder group. Self-reported social impairments predicted depression in adults with autism spectrum disorder when accounting for symptom severity and cognitive ability. These findings suggest that more self-perceived social impairments are related to depressive disorders in autism spectrum disorder, and may help clinicians identify individuals who are vulnerable in developing a co-occurring depressive disorder. Future directions include follow-up studies with larger cohorts and longitudinal designs to support inferences regarding directionality of these relationships.

"I wouldn't know where to start": Perspectives from clinicians, agency leaders, and autistic adults on improving community mental health services for autistic adults

LAY ABSTRACT

Most autistic adults struggle with mental health problems, such as anxiety and depression. However, they often have trouble finding effective mental health treatment in their community. The goal of this study was to identify ways to improve community mental health services for autistic adults. We interviewed 22 autistic adults with mental healthcare experience, 44 community mental health clinicians (outpatient therapists, case managers, and intake coordinators), and 11 community mental health agency leaders in the United States. Our participants identified a variety of barriers to providing quality mental healthcare to autistic adults. Across all three groups, most of the reported barriers involved clinicians' limited knowledge, lack of experience, poor competence, and low confidence working with autistic adults. All three groups also discussed the disconnect between the community mental health and developmental disabilities systems and the need to improve communication between these two systems. Further efforts are needed to train clinicians and provide follow-up consultation to work more effectively with autistic adults. A common suggestion from all three groups was to include autistic adults in creating and delivering the clinician training. The autistic participants provided concrete recommendations for clinicians, such as consider sensory issues, slow the pace, incorporate special interests, use direct language, and set clear expectations. Our findings also highlight a need for community education about co-occurring psychiatric conditions with autism and available treatments, in order to increase awareness about treatment options.

Is Autism Inborn And Lifelong For Everyone?

Autism or autism spectrum disorder (ASD) is described as a lifelong condition with core behavioural symptoms appearing during infancy or early childhood. Genetic and other effects occurring during the earliest times of life are thought to play a significant contributory role to the presentation of autism, denoting that autism is typically seen as an innate or inborn condition. Such descriptions have, and continue to, define autism research and clinical practice. Inspection of the existing research literature, however, suggests that within the vast heterogeneity of autism, not everyone experiences autism in such a prescribed way. Various reports have observed the presentation of "acquired autism" following a period of typical development. Other findings have documented an abatement of clinically relevant autistic features and related comorbid pathology for some. Such reports offer important insights into the heterogeneity and complexity of autism.

Prevalence of co-occurring mental health diagnoses in the autism population: a systematic review and meta-analysis

BACKGROUND

Co-occurring mental health or psychiatric conditions are common in autism, impairing quality of life. Reported prevalences of co-occurring mental health or psychiatric conditions in people with autism range widely. Improved prevalence estimates and identification of moderators are needed to enhance recognition and care, and to guide future research.

METHODS

In this systematic review and meta-analysis, we searched MEDLINE, Embase, PsycINFO, Scopus, Web of Science, and grey literature for publications between Jan 1, 1993, and Feb 1, 2019, in English or French, that reported original research using an observational design on the prevalence of co-occurring mental health conditions in people with autism and reported confirmed clinical diagnoses of the co-occurring conditions and autism using DSM or ICD criteria. For co-occurring mental health conditions reported with at least 15 datapoints (studies), we assessed risk of bias and we determined pooled estimates of prevalence for different co-occurring conditions in autism using random-effects models, and descriptively compared these with prevalence estimates for the general population from the literature (post hoc). We investigated heterogeneity in prevalence estimates using random-effects meta-regression models. This systematic review is registered with PROSPERO, CRD42018103176.

FINDINGS

Of 9746 unique studies identified, 432 were selected for full-text review. 100 studies were eligible for inclusion in our qualitative synthesis, of which 96 were included in our meta-analyses. 11 categories of co-occurring conditions were investigated, of which eight conditions were included in the meta-analyses and three were descriptively synthesised (ie, trauma and stressor-related disorders, substance-related and addictive disorders, and gender dysphoria). From our meta-analyses, we found overall pooled prevalence estimates of 28% (95% CI 25-32) for attention-deficit hyperactivity disorder; 20% (17-23) for anxiety disorders; 13% (9-17) for sleep-wake disorders; 12% (10-15) for disruptive, impulse-control, and conduct disorders; 11% (9-13) for depressive disorders; 9% (7-10) for obsessive-compulsive disorder; 5% (3-6) for bipolar disorders; and 4% (3-5) for schizophrenia spectrum disorders. Estimates in clinical sample-based studies were higher than in population-based and registry-based studies, and these estimates were mostly higher than those in the general population (post hoc). Age, gender, intellectual functioning, and country of study were associated with heterogeneity in prevalence estimates, yet remaining heterogeneity not explained was still substantial (all I² >95%).

INTERPRETATION

Co-occurring mental health conditions are more prevalent in the autism population than in the general population. Careful assessment of mental health is an essential component of care for all people on the autism spectrum and should be integrated into clinical practice.

Diametrically opposed associations between academic achievement and social anxiety among university students with and without autism spectrum disorder

Research findings indicate that anxiety, social anxiety in particular, is the most common experience reported by individuals with autism spectrum disorder (ASD) attending postsecondary education. Among students without ASD, higher levels of social anxiety have been postulated to correlate with impaired academic achievement; restriction of one's social network because of anxiety is thought to lead to reduction of access to resources important for learning such as social/emotional support and collaborative learning. However, despite growing interest in the outcomes of young students with ASD, no research has studied the associations between academic achievement and anxiety among students with ASD. This study examined the association between social anxiety and grade point average (GPA) among university students: 55 diagnosed with ASD, 31 without ASD but high levels of social anxiety, and 25 without ASD and with low levels of social anxiety (controls). GPAs were significantly lower for the ASD group than for the two non-ASD groups. Among students without ASD, a negative correlation between social anxiety and grades was observed whereas the reverse pattern was found for the ASD group, meaning that for students with ASD, higher levels of social anxiety were associated with higher grades. Additionally, in a regression analysis, ASD diagnosis, social anxiety, and the interaction of group × social anxiety significantly predicted GPA. Possible explanations for this finding, as well as implications for interventions among this population of high-functioning students with ASD, are discussed. Autism Res 2019, 12: 1376-1385. © 2019 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: This study compared the relationship between levels of social anxiety and grades in students with autism spectrum disorder (ASD) and in students without ASD who had either high social anxiety or low social anxiety (controls). Among the group with ASD, higher levels of social anxiety were associated with higher grades, whereas the reverse pattern was found among the other groups. This finding's implications for interventions among students with ASD are discussed.

Child and Family Characteristics that Predict Autism Spectrum Disorder Specialty Clinic Appointment Attendance and Alignment with Providers

We examined factors contributing to initial appointment attendance, alignment between parents' pre-visit and clinicians' diagnostic impressions, and family commitment to follow-ups at an autism spectrum disorder (ASD) specialty clinic. Sample sizes were n = 6558 (initial), n = 1430 (alignment), and n = 1353 (follow-up). Parents completed surveys and clinicians provided their ASD diagnostic impressions. When children were not receiving intervention, families were less likely to keep their initial appointment. Families residing long distances and having older children were less likely to keep their initial and follow-up appointments. African American families were less likely to keep their initial appointment and expressed initial doubts with providers about the diagnosis. Findings suggest that some children are not getting diagnostic clarity or accessing timely services.

Satisfaction and Needs in Serious Mental Illness and Autism Spectrum Disorder: The REHABase Psychosocial Rehabilitation Project

OBJECTIVE

The REHABase project is a French observational, prospective, and multicenter cohort study of serious mental illness and autism spectrum disorder (ASD), launched in 2016 for a planned minimum duration of 15 years. The aim is to characterize the care and quality-of-life needs of participants. This article presents initial results from data collection.

METHODS

Psychosocial, cognitive, and functional data were collected at baseline, annually, and after rehabilitation care. Data from the baseline evaluation on diagnoses, medications, well-being, insight, life satisfaction, and care needs are presented. The clinical profiles of REHABase participants with serious mental illness or ASD were assessed in relation to their level of satisfaction with life and well-being in nine life dimensions and their needs, according to their stage of recovery in a five-stage model.

RESULTS

Baseline data were collected for 1,397 participants between January 2016 and August 2018. Main diagnoses were schizophrenia spectrum disorder (49%); ASD (13%); and personality (12%), bipolar (9%), and major depressive (6%) disorders. More than 50% of participants reported needs for care or interventions in four of nine dimensions: employment, cognitive functioning, symptom management, and interpersonal relationships. Nearly half of participants were not in the active stages of recovery (stages 4 and 5), and even those considered to have reached the final stage continued to require help in several areas.

CONCLUSIONS

Most participants had already received psychiatric care for several years, and most remained dissatisfied with their social and emotional life and their psychological well-being.

Increased psychiatric symptoms in university students with autism spectrum disorder are associated with reduced adaptive behavior

High variability in adaptive behavior in cognitively-able adults with autism spectrum disorder has been previously reported, and may be caused by the high prevalence of psychiatric comorbidity in this population. This study's goals were to examine self-reported psychiatric symptoms in students with ASD, and to identify their relative contribution to the variance in adaptive behaviors. The study population included 95 students: 55 diagnosed with ASD (4 females; age range 18-34) who participated in a university integration program (ASD group), and 40 regularly matriculated students (non-ASD group, 7 females; age range 20-36). The ASD group showed a lower adaptive skill level than the non-ASD group as measured by the Adaptive Behavior Assessment System (GAC-ABAS). Significantly higher scores for the ASD group were found for social anxiety, trait anxiety, obsessive-compulsive symptoms, and depression symptoms. The level of adaptive skills correlated negatively and significantly with the severity of social anxiety symptoms in both groups and with severity of obsessive-compulsive symptoms only in the ASD group. Additionally, in a regression model, significant contributions of having an ASD diagnosis and severity of social anxiety explained 41.7% of the variance in adaptive skills. Adequate evaluation and treatment, if needed, are recommended in this population.

Anxiety and depression in adults with autism spectrum disorder: a systematic review and meta-analysis

Adults with autism spectrum disorder (ASD) are thought to be at disproportionate risk of developing mental health comorbidities, with anxiety and depression being considered most prominent amongst these. Yet, no systematic review has been carried out to date to examine rates of both anxiety and depression focusing specifically on adults with ASD. This systematic review and meta-analysis examined the rates of anxiety and depression in adults with ASD and the impact of factors such as assessment methods and presence of comorbid intellectual disability (ID) diagnosis on estimated prevalence rates. Electronic database searches for studies published between January 2000 and September 2017 identified a total of 35 studies, including 30 studies measuring anxiety (n = 26 070; mean age = 30.9, s.d. = 6.2 years) and 29 studies measuring depression (n = 26 117; mean age = 31.1, s.d. = 6.8 years). The pooled estimation of current and lifetime prevalence for adults with ASD were 27% and 42% for any anxiety disorder, and 23% and 37% for depressive disorder. Further analyses revealed that the use of questionnaire measures and the presence of ID may significantly influence estimates of prevalence. The current literature suffers from a high degree of heterogeneity in study method and an overreliance on clinical samples. These results highlight the importance of community-based studies and the identification and inclusion of well-characterized samples to reduce heterogeneity and bias in estimates of prevalence for comorbidity in adults with ASD and other populations with complex psychiatric presentations.

Subtyping the Autism Spectrum Disorder: Comparison of Children with High Functioning Autism and Asperger Syndrome

Since Hans Asperger's first description (Arch Psych Nervenkrankh 117:76-136, 1944), through Lorna Wing's translation and definition (Psychol Med 11:115-129, 1981), to its introduction in the fourth edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM, 1994), Asperger Syndrome has always aroused huge interest and debate, until vanishing in the DSM fifth edition (2013). The debate regarded its diagnostic validity and its differentiation from high functioning autism (HFA). The present study aimed to examine whether AS differed from HFA in clinical profiles and to analyze the impact of DSM-5's innovation. Differences in cognitive, language, school functioning and comorbidities, were revealed when 80 AS and 70 HFA patients (3-18 years) were compared. Results suggested that an AS empirical distinction within autism spectrum disorder should be clinically useful.

Good social skills despite poor theory of mind: exploring compensation in autism spectrum disorder

BACKGROUND

It is proposed that some individuals with Autism Spectrum Disorder (ASD) can 'compensate' for their underlying difficulties (e.g. in theory of mind; ToM), thus demonstrating relatively few behavioural symptoms, despite continued core cognitive deficits. The mechanisms underpinning compensation are largely unexplored, as is its potential impact on mental health. This study aimed to estimate compensation patterns in ASD, by contrasting overt social behaviour with ToM task performance, in order to compare the characteristics of 'Low' and 'High' Compensators.

METHODS

A total of 136 autistic adolescents, from the ongoing Social Relationships Study, completed a range of cognitive tasks, the Autistic Diagnostic Observation Schedule (ADOS) and a self-report anxiety questionnaire. Participants were assigned compensation group status; High Compensators demonstrated good ADOS scores despite poor ToM performance, while Low Compensators demonstrated similarly poor ToM, accompanied by poor ADOS scores.

RESULTS

High Compensators demonstrated better IQ and executive function (EF), but greater self-reported anxiety, compared with Low Compensators. Such differences were not found when comparing individuals who had good versus poor ADOS scores, when ToM performance was good. Other core autistic characteristics (weak central coherence, nonsocial symptoms) did not differentiate the High and Low Compensators.

CONCLUSIONS

IQ, EF and anxiety appear to be implicated in the processes by which certain autistic young people can compensate for their underlying ToM difficulties. This tendency to compensate does not appear to reflect the severity of 'hit' for ASD per se, suggesting that well-compensated individuals are not experiencing a milder form of ASD. The construct of compensation in ASD has implications for research and clinical practice.

Analysis of Asperger Syndrome Using Genetic-Evolutionary Random Support Vector Machine Cluster

Asperger syndrome (AS) is subtype of autism spectrum disorder (ASD). Diagnosis and pathological analysis of AS through resting-state fMRI data is one of the hot topics in brain science. We employed a new model called the genetic-evolutionary random Support Vector Machine cluster (GE-RSVMC) to classify AS and normal people, and search for lesions. The model innovatively integrates the methods of the cluster and genetic evolution to improve the performance of the model. We randomly selected samples and sample features to construct GE-RSVMC, and then used the cluster to classify and extract lesions according to classification results. The model was validated by data of 157 participants (86 AS and 71 health controls) in ABIDE database. The classification accuracy of the model reached to 97.5% and we discovered the brain regions with significant differences, such as the Angular gyrus (ANG.R), Precuneus (PCUN.R), Caudate nucleus (CAU.R), Cuneus (CUN.R) and so on. Our method provides a new perspective for the diagnosis and treatment of AS, and a universal framework for other brain science research as the model has excellent generalization performance.

Prevalence of long-term health conditions in adults with autism: observational study of a whole country population

OBJECTIVES

To investigate the prevalence of comorbid mental health conditions and physical disabilities in a whole country population of adults aged 25+ with and without reported autism.

DESIGN

Secondary analysis of Scotland's Census, 2011 data. Cross-sectional study.

SETTING

General population.

PARTICIPANTS

94% of Scotland's population, including 6649/3 746 584 adults aged 25+ reported to have autism.

MAIN OUTCOME MEASURES

Prevalence of six comorbidities: deafness or partial hearing loss, blindness or partial sight loss, intellectual disabilities, mental health conditions, physical disability and other condition; ORs (95% CI) of autism predicting these comorbidities, adjusted for age and gender; and OR for age and gender in predicting comorbidities within the population with reported autism.

RESULTS

Comorbidities were common: deafness/hearing loss-14.1%; blindness/sight loss-12.1%; intellectual disabilities-29.4%; mental health conditions-33.0%; physical disability-24.0%; other condition-34.1%. Autism statistically predicted all of the conditions: OR 3.3 (95% CI 3.1 to 3.6) for deafness or partial hearing loss, OR 8.5 (95% CI 7.9 to 9.2) for blindness or partial sight loss, OR 94.6 (95% CI 89.4 to 100.0) for intellectual disabilities, OR 8.6 (95% CI 8.2 to 9.1) for mental health conditions, OR 6.2 (95% CI 5.8 to 6.6) for physical disability and OR 2.6 (95% CI 2.5 to 2.8) for other condition. Contrary to findings within the general population, female gender predicted all conditions within the population with reported autism, including intellectual disabilities (OR=1.4).

CONCLUSIONS

Clinicians need heightened awareness of comorbidities in adults with autism to improve detection and suitable care, especially given the added complexity of assessment in this population and the fact that hearing and visual impairments may cause additional difficulties with reciprocal communication which are also a feature of autism; hence posing further challenges in assessment.

Predictors of quality of life for autistic adults

Research with adults on the autism spectrum is as yet limited in scope and quality. The present study describes quality of life (QoL) of a large sample of autistic adults in the UK and investigates characteristics that may be predictive of QoL. A total of 370 autistic adults from the Adult Autism Spectrum Cohort-UK (ASC-UK) completed the WHOQoL-BREF, and the Social Responsiveness Scale (SRS, autism symptom severity), along with the ASC-UK registration questionnaire giving information on mental health and their life situation. QoL for autistic adults was lower than for the general population for each WHOQoL domain. Younger participants reported higher QoL than older participants in psychological and environment domains. Males reported higher physical QoL than females, and females reported higher social QoL than males. Significant positive predictors of QoL were: being employed (physical QoL), receiving support (social and environment QoL), and being in a relationship (social QoL). Having a mental health condition and higher SRS total score were negative predictors of QoL across all four domains. Autistic adults require access to effective mental health interventions, and informal and formal support for their social difficulties, to improve their quality of life. Autism Res 2018, 11: 1138-1147. © 2018 The Authors Autism Research published by International Society for Autism Research and Wiley Periodicals, Inc. LAY SUMMARY: There has been limited research into the lived experience of autistic adults. Using the World Health Organization quality of life measure, we found that autistic people (370) in the UK reported their quality of life to be lower than that of the general population. Better quality of life was associated with being in a relationship; those with a mental health condition had poorer quality of life. This research suggests some ways in which autistic people can be helped to improve their quality of life.

Neurodevelopmental disorders: prevalence and comorbidity in children referred to mental health services

BACKGROUND

Accurate prevalence rates of the neurodevelopmental disorders (ND) and comorbid conditions in child and adolescent mental health services (CAMHS) are essential for treatment planning and organization of health care. However, valid and reliable prevalence estimates from Nordic CAMHS populations are scarce, and the published findings vary.

AIMS

To report prevalence rates of ND (attention-deficit hyperactivity disorder: ADHD, tic disorder: TD or autism spectrum disorder: ASD) and comorbid disorders by a validated diagnostic instrument in children referred to CAMHS outpatient clinics.

METHODS

Parents of 407 consecutively referred children aged 7-13 years were interviewed with the semistructured interview schedule for affective disorders and schizophrenia, present and lifetime version (Kiddie-SADS-PL) at time of admittance.

RESULTS

One or more ND was diagnosed in 226 children (55.5%; 69.9% boys): ADHD (44.5%; 68.5% boys); TD (17.7%; 77.8% boys) and ASD (6.1%; 76% boys). Among children with ND 70 (31.0%) had only one ND with no comorbid disorder, 49 (21.7%) had more than one ND (homotypic comorbidity) and 131 (58%) had a non-ND psychiatric disorder (heterotypic comorbidity). Anxiety disorders were the most frequently occurring heterotypic comorbidity in all three ND. Comorbid depressive disorder was associated with older age, and comorbid anxiety disorder with female gender.

CONCLUSION

In children referred to CAMHS, ND constitute the most frequently occurring group of disorders, with high rates of both homotypic and heterotypic comorbidity. This needs to be taken into consideration in health service planning and treatment delivery.

Community Mental Health Services for Autistic Adults: Good News and Bad News

Many autistic adults experience psychiatric conditions such as anxiety and depression. However, autistic adults often do not receive effective and affordable mental health (MH) treatment. Untreated psychiatric conditions in autistic adults are associated with a host of negative outcomes, including adaptive functioning impairments, difficulties with employment and independent living, and poor quality of life. The purpose of this Perspectives piece is to shed light on the current state of community MH services in the United States for autistic adults with co-occurring psychiatric conditions. Drawing on the available research and clinical experiences, we aim to (1) highlight positive developments in community mental healthcare for autistic adults; (2) summarize the barriers that continue to exist for autistic adults in need of MH services; and (3) provide recommendations for autistic adults and their families, community MH clinicians, and MH systems administrators to consider. Significant work is needed to provide autistic adults with affordable quality MH services. This Perspectives piece presents a summary of the needed changes and specific methods to continue to improve community MH services for autistic adults.

Behavioral, Cognitive and Neural Markers of Asperger Syndrome

Asperger syndrome (AS) is a subtype of Autism Spectrum Disorder (ASD) characterized by major problems in social and nonverbal communication, together with limited and repetitive forms of behavior and interests. The linguistic and cognitive development in AS is preserved which help us to differentiate it from other subtypes of ASD. However, significant effects of AS on cognitive abilities and brain functions still need to be researched. Although a clear cut pathology for Asperger has not been identified yet, recent studies have largely focused on brain imaging techniques to investigate AS. In this regard, we carried out a systematic review on behavioral, cognitive, and neural markers (specifically using MRI and fMRI) studies on AS. In this paper, behavior, motor skills and language capabilities of individuals with Asperger are compared to those in healthy controls. In addition, common findings across MRI and fMRI based studies associated with behavior and cognitive disabilities are highlighted.

Adults with autism spectrum conditions experience increased levels of anomalous perception

Autism spectrum condition (ASC) is characterised by differences in social interaction and behavioural inflexibility. In addition to these core symptoms, atypical sensory responses are prevalent in the ASC phenotype. Here we investigated anomalous perception, i.e. hallucinatory and/or out of body experiences in adults with ASC. Thirty participants with an ASC diagnosis and thirty neurotypical controls completed the Cardiff Anomalous Perception Scale (CAPS) and the Social Responsiveness Scale (SRS-2). The CAPS is a 32-item questionnaire that asks participants to indicate whether or not they experience a range of anomalous and out of body experiences, and to rate how intrusive and distressing these experiences are. The SRS-2 asks participants to rate the extent to which they identify with a series of 65 statements that describe behaviours associated with the autism phenotype. We found that total CAPS score was significantly higher in the participants with ASC (mean = 14.8, S.D. = 7.9) than the participants without ASC (mean = 3.6, S.D. = 4.1). In addition, the frequency of anomalous perception, the level of distraction and the level of distress associated with the experience were significantly increased in participants with ASC. Importantly, both the frequency of anomalous perceptual experiences and the level of distress caused by anomalous perception in this sample of adults with ASC were very similar to that reported previously in a sample of non-autistic participants who were being treated in hospital for a current psychotic episode. These data indicate that anomalous perceptual experiences are common in adults with ASC and are associated with a high level of distress. The origins of anomalous perception in ASC and the implication of this phenomenon are considered.

Autism spectrum disorder: outcomes in adulthood

PURPOSE OF REVIEW

Until recently, there has been little systematic study of adult life among individuals with autism spectrum disorder (ASD) but recognition of the high psychological and social costs of ASD has led to an increase in adult-focused research over the past decade. The aim of this review is to summarize recent empirical findings on outcomes for adults with ASD.

RECENT FINDINGS

Most research on adult outcomes in ASD indicates very limited social integration, poor job prospects and high rates of mental health problems. However, studies vary widely in their methodology, choice of measures and selection of participants. Thus, estimates of how many adults have significant social and mental health problems are often conflicting. There is little consistent information on the individual, familial or wider social factors that may facilitate more positive social and psychological outcomes. There is a particular dearth of research on older individuals with ASD.

SUMMARY

The very variable findings reported in this review reflect the problems of conducting research into lifetime outcomes for individuals with a condition as heterogeneous as ASD. Much more systematic research is needed to delineate different patterns of development in adulthood and to determine the factors influencing these trajectories.

Atypical sensory profiles as core features of adult ADHD, irrespective of autistic symptoms

BACKGROUND

Abnormal sensory sensitivity is a feature of autism-spectrum disorder (ASD), but is also reported in attention-deficit/hyperactivity disorder (ADHD). In many cases, ADHD and ASD are comorbid. This study investigated the prevalence of sensory hyper- and hyposensitivity among adults with ADHD, controlling for autistic symptoms.

METHOD

One hundred and sixteen adults diagnosed with ADHD completed the Adolescent/Adult Sensory Profile-NL (AASP-NL) and the Autism-spectrum Quotient (AQ) questionnaires. Prevalences of hyper- and hyposensitivity and autism-spectrum symptoms were compared to norm values. Multivariate binary logistic regressions were used to determine the association of autistic symptoms, age, gender, ADHD subtype, self-reported severity of ADHD symptoms, comorbid disorders, and use of medication on the sensory hypo- and hypersensitivity in adults with ADHD.

RESULTS

Adults with ADHD had more autistic symptoms, and they had both more hyper- and hyposensitivity compared to norm groups. This was especially apparent in the Activity level and Auditory sensory modalities. Sensory hypo- and hypersensitivity were both related to an increased ADHD score, even showing a dose-response relationship, but not to any autistic symptom or comorbid disorder. As much as 43% of the females with ADHD reported sensory hypo- and/or hypersensitivity, compared to 22% of the men.

CONCLUSIONS

Sensory hypo- and hypersensitivity may be viewed as key features of adult ADHD, especially in females, regardless of any autistic symptoms. Future research should be directed at the implications of this sensory dysregulation for the understanding of the pathophysiology of (female) ADHD, and on the usefulness of assessment of atypical sensory profiles in the diagnostic procedure of ADHD in adults.
