Scene construction ability in neurotypical and autistic adults.

People with autism spectrum conditions (ASC) have difficulties imagining events, which might result from difficulty mentally generating and maintaining a coherent spatial scene. This study compared this scene construction ability between autistic (N = 55) and neurotypical (N = 63) adults. Results showed that scene construction was diminished in autistic compared to neurotypical participants, and participants with fewer autistic traits had better scene construction ability. ASC diagnosis did not influence the frequency of mentions of the self or of sensory experiences. Exploratory analysis suggests that scene construction ability is associated with the ability to understand our own and other people's mental states, and that these individual-level preferences/cognitive styles can overrule typical group-level characteristics.

B - 16 Prevalence of Comorbid Diagnoses among Individuals with a Clinical Vs. Self-Diagnosis of Autism Spectrum Conditions (ASC).

The evolution of ASC has changed drastically since its initial conceptualization. Therefore, it is possible that numerous individuals remain undiagnosed and untreated based on lack of knowledge about this condition. Diagnoses of ASC often include multiple other detrimental comorbid disorders. To elucidate whether the issue of underdiagnosis is relevant, it is important to determine if there are individuals who believe they qualify for a diagnosis of ASC, who remain undiagnosed. This study aims to compare the prevalence of comorbid diagnoses between individuals diagnosed by a clinician with those who self-report having ASC. 391 adults who self-reported have ASC (ages 18+) were recruited via Research Match. The call for subjects stated that the study was looking for individuals with a diagnosis of ASC to participate. Volunteers were asked to indicate if they were diagnosed with ASC, and if so, from whom they were diagnosed. One of the options for who gave the diagnosis was "self". Finally, participants were asked to indicate any comorbid diagnoses they had. Of the 391 participants, 180 self-reported having ASC, and 211 participants indicated that they were diagnosed by a clinician. A one-way ANOVA was significant, indicating significant differences among groups, F(5,389) = 2.84, p = 0.016. Specifically, those who were diagnosed by a psychiatrist (M = 4.41) had significantly more comorbid diagnoses when compared with those who were self-diagnosed (M = 3.62). As 180 participants who claimed to have ASC were not clinically diagnosed, the results suggest that under-diagnoses of this condition may be prevalent.

Gender Differences in Autism Diagnostics

Autism spectrum condition (ASC) is predominantly diagnosed in boys and men. There is evidence that this is also because girls and women with ASC don't receive a diagnosis, or, if they do, only later in life. This study investigates gender differences in diagnosis, support needs, mental health, and life satisfaction among individuals with autism spectrum condition (ASC) in Germany. Data of an online questionnaire study with 659 persons with ASC from 3-67 years of age living in Bavaria, Germany, were analyzed (215 thereof were female). It was found that women with ASC are diagnosed 7-11 years later than men and are more likely to receive at least one misdiagnosis. They are more likely than men to have unmet educational support needs and comorbid internalizing psychiatric disorders. The results of this study point towards a strong gender bias in clinical diagnosis of ASC in Germany and need for improvements in the case of women.

Self-reported autistic traits and psychosocial outcomes among university students in Malaysia.

Most research on autism spectrum conditions is done on young children and not as much on young adults with autism spectrum conditions. Because of this, not much is known about how common autism spectrum conditions are in young adults and how they affect their mental and social health, especially in Southeast Asia. Based on self-reports, 2.8% of the 2732 university students we looked at in Malaysia might have been diagnosed or thought to have an autism spectrum condition. Students who said they had or thought they had autism spectrum conditions had lower self-efficacy, more stress and a lower quality of life than students who said they did not have autism spectrum conditions. The results showed that university students with autism spectrum condition are more likely to have bad psychological and social outcomes than their peers without autism spectrum condition. Also, the link between autistic traits and psychosocial outcomes could depend on the culture.

“Fake it ‘till you make it”: Authenticity and wellbeing in late diagnosed autistic women

The diagnosis of autism spectrum condition (ASC) in women is increasing, prompting research into the gendered experience and presentation of female ASC. To complement this growing body of research, the current study utilised a qualitative approach informed by a feminist disability framework to explore how the intersecting dimensions of difference, gender, and ASC influence autistic women’s subjectivity and wellbeing. Drawing on the experiences of eight late-diagnosed autistic women, thematic analysis highlighted experiences of early marginalisation, challenges of living outside gendered social norms, the psychological and emotional consequences of masking, and the impact of diagnosis on subjectivity, identity, and wellbeing. Participants developed their authenticity and personhood within a performative social context that required masking of the self, a complex process with wide-ranging consequences. Findings also highlight the importance of acceptance, representation, and community for the wellbeing of autistic women. This research challenges the dominant, masculinised construction of ASC. It highlights the need for the ontological status of ASC to be reconceptualised to incorporate diverse experiences of the condition across the gender spectrum. Future research should explore how psychology can facilitate this reconceptualisation.

The Social Support Network of Adults with an Autism Spectrum Condition: An Exploration Using the Network in Action-Questionnaire

Actively involving the network during treatment, as recommended in Autism Spectrum Condition (ASC) guidelines, can be facilitated with the Network in Action-Questionnaire (NiA-Q), which identifies the current and potential sources of social support. The aims of this study were to (1) examine the factor structure of the NiA-Q and (2) to explore the self- and proxy-report on the social network. Before the start of treatment in a mental health institution, 193 adults with an ASC diagnosis and 84 proxies completed the NiA-Q. Factor analysis showed two factors: positive social support and interpersonal distress. Self- and proxy-report on the NiA-Q did not differ for most variables, except for social network wishes. The NiA-Q provides a basis for network involvement and strengthening.

Autism in girls and the pre-referral environment

AimsThis literature review sought to identify and highlight any sex specific factors in the diagnosis of autism spectrum conditions during the pre-referral period which might affect diagnosis rates in ASD in girls. The null hypothesis was that there are no sex specific factors that affect referral and diagnosis of ASD in girls.BackgroundHistorically, boys are diagnosed with ASD more than girls but rates vary depending on clinical population characteristics. Diagnosis trends continue to demonstrate a large male excess. The concept of autism as a predominantly male condition has been challenged and there is increased focus on females with high functioning autism who are not being detected as easily.Various theories exist as to why this is the case.There are high rates of suicidality in ASD and risk of death by suicide is higher in ASD women (the reciprocal of the suicide rates in general population where more men complete suicide). Women with high functioning autism represent an at risk group. Undetected autism in females may be complicated by ‘camouflaging’ or masking of symptoms which puts a large strain on individuals functioning and mental health. Costs to society and the individual are large.However, early identification and intervention improves outcomes such as activities of daily living and social behaviours.MethodAn electronic literature search was completed using MEDLINE, PsycINFO and EMBASE in November 2018. Key terms were: (‘child*’ OR ‘adolescent’ OR ‘young pe*’) AND (‘ASD’ OR ‘autism’ OR ‘asperger*’ OR ‘high functioning*’ OR ‘PDD’ OR ‘Pervasive developmental*’) AND (‘girl*’ OR ‘sex’ OR ‘gender’). Papers were excluded on a number of grounds.Result11 papers were included in the review from an initial 2823 abstracts.ConclusionA number of papers highlighted important learning points. Some of the more original conclusions included that we require more studies comparing populations of girls with ASD to high risk, high functioning girls and female controls to clarify features particular to the ‘female phenotype’. Delays in diagnosis in girls appears to pre-date assessment so further thought on how to educate and support referral sources (caregivers and schools) on how to identify girls with autism is recommended and would be informed by further research focus on the previous point. Active case ascertainment should be considered in future research and follow-up of girls who do not receive a diagnosis at initial assessment were additional learning points that came from the review.

ADOS-Eye-Tracking: The Archimedean Point of View and Its Absence in Autism Spectrum Conditions.

Face perception and emotion categorization are widely investigated under laboratory conditions that are devoid of real social interaction. Using mobile eye-tracking glasses in a standardized diagnostic setting while applying the Autism Diagnostic Observation Schedule (ADOS-2), we had the opportunity to record gaze behavior of children and adolescents with and without Autism Spectrum Conditions (ASCs) during social interaction. The objective was to investigate differences in eye-gaze behavior between three groups of children and adolescents either (1) with ASC or (2) with unconfirmed diagnosis of ASC or (3) with neurotypical development (NTD) during social interaction with an adult interviewer in a diagnostic standard situation using the ADOS-2. In a case control study, we used mobile eye-tracking glasses in an ecologically valid and highly standardized diagnostic interview to investigate suspected cases of ASC. After completion of the ASC diagnostic gold standard including the ADOS-2, the participants were assigned to two groups based on their diagnosis (ASC vs. non-ASC) and compared with a matched group of neurotypically developed controls. The primary outcome measure is the percentage of total dwell times assessed for different areas of interest (AOI) with regard to the face and body of a diagnostic interviewer and the surrounding space. Overall, 65 children and adolescents within an age range of 8.3–17.9 years were included in the study. The data revealed significant group differences, especially in the central-face area. Previous investigations under laboratory conditions gave preferential attention to the eye region during face perception to describe differences between ASC and NTD. In this study – using an ecologically valid setting within a standard diagnostic procedure – the results indicate that neurotypically developed controls seem to process faces and facial expressions in a holistic manner originating from the central-face region. Conversely, participants on the Autism Spectrum (tAS) seem to avoid the central-face region and show unsystematic gaze behavior, not using the preferred landing position in the central-face region as the Archimedean point of face perception. This study uses a new approach, and it will be important to replicate these preliminary findings in future research.

Autism screening and conditional cash transfers in Chile: Using the Quantitative Checklist (Q-CHAT) for early autism detection in a low resource setting.

Getting a diagnosis of autism can take long, because autism is different across people, but also because it depends on the way it gets diagnosed. This is especially important in poorer countries or in the case of poor people living in wealthier countries that have significant groups of disadvantaged communities. We adapted a 10-item version of the Q-CHAT-25 questionnaire for use in routine health check-ups programme in Chile and recruited 287 participants under the age of three divided into three groups: Controls (125), Developmental Delay (149) and Autism Spectrum Condition (13). Our results show that a short questionnaire for autism screening can be successfully applied in a health-check programme in poor resource settings. Our results show that our questionnaire had good overall performance, not different to its longer version, the Q-CHAT-25. Our questionnaire was autism specific, with good sensitivity and reliability, and is suitable to be used in a screening setting. This study provides evidence that the implementation of Autism Spectrum Condition screening programmes using the Q-CHAT-10 provides value for money and improves diagnosis of Autism Spectrum Condition in those participating in routine health check-up programmes in developing countries or poor areas of wealthy countries.

Practical applications of brief screening questionnaires for autism spectrum disorder in a psychiatry outpatient setting.

ObjectivesThis study was designed to examine the diagnostic performance of the social and communication disorders checklist (SCDC) and strength and difficulties questionnaire (SDQ) to detect autism spectrum conditions (ASC), along with the social responsiveness scale‐second edition (SRS‐2) as reference, in a psychiatry outpatient setting.MethodsWe translated the SCDC into Japanese since its Japanese version was unavailable. We examined its test‐retest reliability as well as the internal consistency reliability and diagnostic performance of the three questionnaires among 41 Japanese psychiatric outpatients, using the best‐estimate diagnosis of ASC based on the diagnostic interview for social and communication disorders, as a gold standard.ResultsThe test‐retest reliability was high for the SCDC. Although the internal consistency reliability was high for the SCDC and SRS‐2, that was low for the prosocial and peer problem subscales of the SDQ. The performance of the SCDC, SDQ, and SRS‐2 to detect ASC was moderate: the area under the ROC curve of 0.78, 0.78, and 0.84, respectively.ConclusionsAlthough questionnaires to detect ASC, including the three examined, generally have only moderate performance in this setting, these can be successfully applied to high‐risk populations such as psychiatry outpatients, when multi‐level rather than dichotomous likelihood ratios are used.

Autism Spectrum Social Stories In Schools Trial 2 (ASSSIST2): study protocol for a randomised controlled trial analysing clinical and cost-effectiveness of Social Stories\u2122 in primary schools

BackgroundInterventions designed to support children with a diagnosis of Autism Spectrum Conditions (ASC) can be time consuming, needing involvement of outside experts. Social Stories™ are a highly personalised intervention aiming to give children with ASC social information or describing an otherwise difficult situation or skill. This can be delivered daily by staff in education settings. Studies examining Social Story™ use have yielded mostly positive results but have largely been single case studies with a lack of randomised controlled trials (RCTs). Despite this numerous schools are utilising Social Stories™, and a fully powered RCT is timely.MethodsA multi-site pragmatic cluster RCT comparing care as usual with Social Stories™ and care as usual. This study will recruit 278 participants (aged 4–11) with a clinical diagnosis of ASC, currently attending primary school in the North of England. Approximately 278 school based staff will be recruited to provide school based information about participating children with approximately 140 recruited to deliver the intervention. The study will be cluster randomised by school. Potential participants will be screened for eligibility prior to giving informed consent. Follow up data will be collected at 6 weeks and 6 months post randomisation and will assess changes in participants’ social responsiveness, goal based outcomes, social and emotional health. The primary outcome measure is the Social Responsiveness Scale Second Edition (SRS-2) completed by school based staff at 6 months. Approvals have been obtained from the University of York’s Research Governance Committee, Research Ethics Committee and the Health Research Authority. Study results will be submitted for publication in peer-reviewed journals and disseminated to participating families, educational staff, local authority representatives, community groups and Patient and Participant Involvement representatives. Suggestions will be made to NICE about treatment evidence dependent on findings.DiscussionThis study addresses a much used but currently under researched intervention and results will inform school based support for primary school children with a diagnosis of ASC.Trial registrationThe trial is registered on the ISRCTN registry (registration number: ISRCTN11634810). The trial was retrospectively registered on 23rd April 2019.

When the mask comes off: Mothers' experiences of parenting a daughter with autism spectrum condition.

Parents of children with autism spectrum condition report increased stress and difficulties compared with parents of typically developing children. Our knowledge and understanding of how autism spectrum condition presents in autistic females is currently limited and parents of this population may experience challenges when raising their daughter. Given that mothers are often the main caregiver of a child with autism spectrum condition, they may have useful insights into the experiences of parenting a daughter with autism spectrum condition. Therefore, a qualitative study was undertaken to explore what mothers' experiences are of parenting a daughter with autism spectrum condition. Semi-structured interviews were conducted with 10 mothers of daughters with autism spectrum condition. The interviews were analysed using interpretative phenomenological analysis. Five main themes emerged from the qualitative study ('Girls have autism too', 'She's a chameleon', 'The impact of the diagnosis', 'Impact on mums' and 'Day-to-day life'). The findings of this study expand our current knowledge of the experiences and challenges faced by mothers raising a daughter with autism spectrum condition. Mothers hold a vast amount of knowledge on their daughters' autism spectrum condition which could inform the diagnostic process and clinical practice. Considering these results, it is important that clinicians support mothers and the family system around children with an autism spectrum condition diagnosis.

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

ABSTRACTIncreasingly adults over the age of 50 are receiving a diagnosis of autism spectrum condition. Growing up in a time when autism was poorly recognised, these adults have lived unknowingly with the condition and face readjustment. This paper reports the first study to investigate this population. Nine adults over the age of 50, who had recently been diagnosed with ASC, were interviewed, and thematic analysis was used to analyse the transcripts. Results showed that the participants had received treatment for anxiety and depression. They reported ASC behaviours in their childhood and growing up they felt isolated and alien. Receiving a diagnosis was seen as a positive step and allowed for a reconfiguration of self and an appreciation of individual needs. Given the positive aspects of receiving a late diagnosis, more work is needed to identify older adults with undiagnosed ASC.

Incorporating the Power Threat Meaning Framework into an autism and learning disability team

This article presents our personal experience of using the PTMF in a National specialist service working with children, adolescents, families and adults with a diagnosis of Autism Spectrum Condition (ASC), or intellectual disability. We suggest that regardless of one’s understanding of the nature of ASC, the PTMF offers a broader, contextual understanding of a person’s experience.

Blending Human and Artificial Intelligence to Support Autistic Children’s Social Communication Skills

This article examines the educational efficacy of a learning environment in which children diagnosed with Autism Spectrum Conditions (ASC) engage in social interactions with an artificially intelligent (AI) virtual agent and where a human practitioner acts in support of the interactions. A multi-site intervention study in schools across the UK was conducted with 29 children with ASC and learning difficulties, aged 4--14 years old. For reasons related to data completeness and amount of exposure to the AI environment, data for 15 children was included in the analysis. The analysis revealed a significant increase in the proportion of social responses made by ASC children to human practitioners. The number of initiations made to human practitioners and to the virtual agent by the ASC children also increased numerically over the course of the sessions. However, due to large individual differences within the ASC group, this did not reach significance. Although no evidence of transfer to the real-world post-test was shown, anecdotal evidence of classroom transfer was reported. The work presented in this article offers an important contribution to the growing body of research in the context of AI technology design and use for autism intervention in real school contexts. Specifically, the work highlights key methodological challenges and opportunities in this area by leveraging interdisciplinary insights in a way that (i) bridges between educational interventions and intelligent technology design practices, (ii) considers the design of technology as well as the design of its use (context and procedures) on par with one another, and (iii) includes design contributions from different stakeholders, including children with and without ASC diagnosis, educational practitioners, and researchers.

Risk markers for suicidality in autistic adults

BackgroundResearch has shown high rates of suicidality in autism spectrum conditions (ASC), but there is lack of research into why this is the case. Many common experiences of autistic adults, such as depression or unemployment, overlap with known risk markers for suicide in the general population. However, it is unknown whether there are risk markers unique to ASC that require new tailored suicide prevention strategies.MethodsThrough consultation with a steering group of autistic adults, a survey was developed aiming to identify unique risk markers for suicidality in this group. The survey measured suicidality (SBQ-R), non-suicidal self-injury (NSSI-AT), mental health problems, unmet support needs, employment, satisfaction with living arrangements, self-reported autistic traits (AQ), delay in ASC diagnosis, and ‘camouflaging’ ASC. One hundred sixty-four autistic adults (65 male, 99 female) and 169 general population adults (54 males, 115 females) completed the survey online.ResultsA majority of autistic adults (72%) scored above the recommended psychiatric cut-off for suicide risk on the SBQ-R; significantly higher than general population (GP) adults (33%). After statistically controlling for a range of demographics and diagnoses, ASC diagnosis and self-reported autistic traits in the general population significantly predicted suicidality. In autistic adults, non-suicidal self-injury, camouflaging, and number of unmet support needs significantly predicted suicidality.ConclusionsResults confirm previously reported high rates of suicidality in ASC, and demonstrate that ASC diagnosis, and self-reported autistic traits in the general population are independent risk markers for suicidality. This suggests there are unique factors associated with autism and autistic traits that increase risk of suicidality. Camouflaging and unmet support needs appear to be risk markers for suicidality unique to ASC. Non-suicidal self-injury, employment, and mental health problems appear to be risk markers shared with the general population that are significantly more prevalent in the autistic community. Implications for understanding and prevention of suicide in ASC are discussed.

Sensory and motor differences in Autism Spectrum Conditions and developmental coordination disorder in children: A cross-syndrome study

Recent research has shown that Developmental coordination disorder (DCD) can present with some similar symptomology as Autism Spectrum Conditions (ASC). This paper therefore explored the similarities and differences in coordination and sensory responsivity between DCD and ASC. 77 children took part: 42 (35 male, 7 female) with ASC (ages 7–21: mean age 12.23 years), 26 (19 male, 7 female) with DCD (ages 7–21; mean age 11.07 years) and 9 (2 male, 7 female) with ASC and DCD (ages 8–15; mean age 12.27). All groups completed a battery of validated parent report measures online that included motor coordination (DCDQ), sensory responsivity (SPC-R) and social communication measures (AQ). Results showed no significant differences in coordination, and some significant differences in sensory responsivity between ASC and DCD (increased visual and auditory responsivity and decreased proprioception). Exploratory analysis showed that these differences showed good validity in identifying the diagnosis of ASC and DCD. These results elucidate the underlying causes of motor coordination difficulties in both conditions. Specifically, ASC coordination difficulties appear linked to visual processing impairments, whilst DCD coordination difficulties appear to be linked to spatial processing. This may aid better diagnosis and intervention for these conditions.

Instructions to mimic improve facial emotion recognition in people with sub-clinical autism traits.

People tend to mimic the facial expression of others. It has been suggested that this helps provide social glue between affiliated people but it could also aid recognition of emotions through embodied cognition. The degree of facial mimicry, however, varies between individuals and is limited in people with autism spectrum conditions (ASC). The present study sought to investigate the effect of promoting facial mimicry during a facial-emotion-recognition test. In two experiments, participants without an ASC diagnosis had their autism quotient (AQ) measured. Following a baseline test, they did an emotion-recognition test again but half of the participants were asked to mimic the target face they saw prior to making their responses. Mimicry improved emotion recognition, and further analysis revealed that the largest improvement was for participants who had higher scores on the autism traits. In fact, recognition performance was best overall for people who had high AQ scores but also received the instruction to mimic. Implications for people with ASC are explored.

Are autistic traits associated with suicidality? A test of the interpersonal-psychological theory of suicide in a non-clinical young adult sample.

Autism spectrum conditions (ASC) has recently been associated with increased risk of suicidality. However, no studies have explored how autistic traits may interact with current models of suicidal behavior in a non‐clinical population. The current study therefore explored how self‐reported autistic traits interact with perceived burdensomeness and thwarted belongingness in predicting suicidal behavior, in the context of the Interpersonal‐Psychological Theory of Suicide (IPTS). 163 young adults (aged 18–30 years) completed an online survey including measures of thwarted belonging and perceived burdensomeness (Interpersonal Needs Questionnaire), self‐reported autistic traits (Autism Spectrum Quotient), current depression (Centre for Epidemiological Studies Depression Scale), and lifetime suicidality (Suicide Behavior Questionnaire‐Revised). Results showed that burdensomeness and thwarted belonging significantly mediated the relationship between autistic traits and suicidal behavior. Both depression and autistic traits significantly predicted thwarted belonging and perceived burdensomeness. Autistic traits did not significantly moderate the relationship between suicidal behavior and thwarted belonging or perceived burdensomeness. Results suggest that the IPTS provides a useful framework for understanding the influence of autistic traits on suicidal behavior. However, the psychometric properties of these measures need be explored in those with clinically confirmed diagnosis of ASC. Autism Res 2017, 10: 1891–1904. © 2017 The Authors Autism Research published by International Society for Autism Research and Wiley Periodicals, Inc.Lay SummaryRecent research has shown that people with high autistic traits are more likely to attempt suicide. However, no studies have explored why. We found that people with high autistic traits were more likely to experience feelings that they do not belong in the world, are a burden on others, and depression, which may increase their likelihood of attempting suicide. These results suggest that promoting inclusion and independence in those with high autistic traits could help prevent people attempting suicide.

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.
