Data from the National Survey of Children’s Health 2016-2020 was used to examine the association between physical activity and anxiety and depression among autistic youth, non-autistic youth with ADHD, and non-autistic non-ADHD youth. There was a significant negative association between physical activity and anxiety among all groups. Reduction in anxiety or depression associated with greater physical activity was at least as large or larger among autistic or nonautistic youth with ADHD than among non-autistic non-ADHD youth. Unfortunately, even autistic youth who were physically active 4 to 7 days a week showed very high rates of anxiety (54.5%) and depression (23.1%). Very high levels of dual diagnosis of anxiety and depression in autistic youth and youth with ADHD also emerged. Findings highlight a need to determine the cause-and-effect relationships among physical activity, anxiety, and depression across groups and to prioritize mental health screenings and support for autistic youth and youth with ADHD.

PURPOSE: Genetic and environmental risk factors associated with Autism Spectrum Disorders (ASD) continue to be a focus of research worldwide. Consanguinity, the cultural practice of marrying within a family, is common in cultures and societies of the Middle East, North Africa and parts of Asia. Consanguinity has been investigated as a risk factor for ASD in a limited number of studies, with mixed results. We employed registry and survey data from Qatar to evaluate the role of consanguinity as a risk factor for ASD. METHODS: Data were sourced from a national registry and a population-based survey of autism recently conducted in Qatar. We selected a sample of 891 children (mean age: 8.3 years) with (N = 361) or without (N = 530) ASD. Data on consanguinity and covariates were collected through questionnaires and interviews. RESULTS: The prevalence of consanguinity in the overall sample was 41.2% with no significant difference between cases and controls (42.1% vs 41.3%; p = .836). In adjusted multiple logistic regression analyses, consanguinity was not associated with risk of ASD (aOR = 1.065; 95% CI: .751-1.509; NS). CONCLUSION: Parental consanguinity was not associated with autism risk in our study. Replication in other populations with high rates of consanguineous unions is recommended.

INTRODUCTION: Depression impacts many individuals with autism spectrum disorder (ASD), carrying increased risk of functional impairment, hospitalization, and suicide. Prescribing medication to target depression in patients with ASD occurs despite limited available systematic data describing medication management of depression in this population. PURPOSE: The purpose of this study is to discover prescribing patterns for individuals with MDD and ASD during this time period (2004-2012) to inform current and future prescribing practices with historical data. METHOD: Drawing from a large clinical database describing the prescribing practices in patients with ASD, we identified 166 individuals with ASD (mean age 14.5 ± 8.3 years old) who received medication targeting symptoms of depression. We report prescribing rates for specific drugs, drug treatment duration, and reasons for drug discontinuation when applicable. RESULTS: Sertraline, mirtazapine, and fluoxetine were the three most commonly prescribed medications to treat comorbid depression for this patient population. Among 241 drug starts, 123 (49%) drug treatments were continued at the final reviewed follow-up visit (average treatment duration of ± 0.72 years). The most common reason for discontinuation across all medications prescribed was loss of or lack of effectiveness. CONCLUSION: This study raises concern that standard of care pharmacological treatments for depression in individuals with ASD may be less effective than in neurotypical populations. There remains a need to develop effective interventions for depression specifically tailored to the needs of individuals with ASD.

Caregivers of children with attention deficit-hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) experience more stress than caregivers of typically developing children but there is limited research evaluating caregivers’ quality of life (QoL). This study aimed to describe the association of caregiver QoL in children with ASD and/or ADHD. This study included patients with ADHD and/or ASD seen in one pediatric specialty clinic between September 2018-August 2020. Caregivers were classified as those caring for children with ASD-only, ADHD-only, or youth with both conditions (ADHD + ASD). An adapted version of the PedsQL Family Impact Module was used to measure caregiver QoL. The sample included caregivers of 931 children. The majority of these children were male (74.7%), non-Hispanic white (63.3%), and aged 6 to 12 years (57.8%). Across the groups, significant differences were observed in patient age (p < 0.0001), preferred language (p = 0.005), and insurance (p = 0.001). Caregivers of non-Hispanic Black children had 4-times the odds of reporting feeling isolated from others (OR 4.36, 95% CI 1.19-16.00 p = 0.03). Those caring for children with ADHD-only had significantly lower odds of reporting helplessness or hopelessness (OR 0.45, 95% CI 0.26-0.80, p = 0.004), and difficulty talking about their child's health with others (OR 0.30, 95% CI 0.17-0.54, p < 0.0001). Similarly, caregivers of children who had ADHD + ASD reported higher odds of difficulty making decisions together as a family (OR 14.18, 95% CI 1.15-17.91, p=0.04) and difficulty solving family problems together (OR 45.12, 95% CI 2.70-752.87), p = 0.008). Caring for children with ADHD and/or ASD may affect caregiver QoL.

PURPOSE: The purpose of this study was to analyze secondary data from three mother-child dyads in order to evaluate how family photographs and training in naturalistic strategies affected the way mothers reminisce with their children with autism spectrum disorders. METHOD: A secondary analysis (i.e., collateral effects) of a single-case dataset was conducted to assess the impact of family photographs and training in naturalistic strategies on the selected variables. RESULTS: The introduction of family photographs showed positive effects on the mother’s reminiscing style and the child’s memory responses across all dyads. Furthermore, additional improvements were observed in these areas after training and coaching in the target strategies. CONCLUSION: This study demonstrates the positive impact of using family photographs and naturalistic based strategies in joint-reminiscing conversations for mothers and children with autism spectrum disorder. The intervention improved the mothers reminiscing style and child’s memory responses, highlighting the potential value of parent-implemented interventions, especially those based on naturalistic strategies, in supporting individuals with autism spectrum disorder and their caregivers.

PURPOSE: The aim of the present study was to explore the meaning of work for the subjective well-being of autistic adults with and without paid (competitive) employment and to evaluate the differences and similarities between these groups. METHODS: Eight focus groups were conducted, including a total of 64 autistic adults. Four groups entailed participants with current paid employment (including part-time) and four groups entailed participants without paid employment. All discussions were audiotaped and transcribed verbatim to enable inductive thematic content analysis. Data were analyzed using ATLAS.ti 9. RESULTS: Generally, both groups viewed paid employment as very important for well-being, albeit for different reasons. Three themes were found: (1) Not having paid employment was associated with lacking societal recognition, and subsequent low self-esteem, which was a dominant theme in those without work; (2) Work can seriously damage (mental) health and well-being, found in both groups; and (3) Paid employment provides many benefits for well-being, with subthemes: ‘purpose,’ ‘social contacts,’ ‘growth and use of talents,’ ‘structure and calmness,’ and ‘income and freedom’, which was a dominant theme in those with paid employment. CONCLUSIONS: Both groups found paid employment highly important for their well-being, albeit for different reasons. However, both also agreed that paid employment can be very harmful to (mental) health and well-being. Suitable, well-supported jobs are important for well-being, may help to buffer stress in other life areas, and may even prevent autistic burnout. More studies are needed on how healthy jobs can be created where autistic individuals get positive energy and experience high well-being. This will also help to reduce socio-economic inequality.

OBJECTIVE: Self-reported memory difficulties are common among older adults, but few studies have examined memory problems among autistic middle-aged and older people. The current study examines self-rated prospective (PM) and retrospective (RM) memory difficulties and their associations with age in middle-aged and older autistic and non-autistic people. METHODS: 350 autistic people (58% assigned-female-at-birth; age-range: 40-83 years) and 350 non-autistic adults matched on age, birth-sex and education level were included in the analysis. Participants completed the Prospective and Retrospective Memory Questionnaire (PRMQ) which includes questions about PM vs. RM (memory type), environment-cued vs. self-cued (cue), and short vs. long delay (delay). RESULTS: Autistic people reported significantly more PM and RM difficulties than the comparison group. Both groups reported more difficulties with PM (vs. RM), self-cued (vs. environment-cued), and short (vs. long) delay. No significant interactions were observed. Among autistic people, younger age was associated with reporting more PM and RM difficulties, but this pattern was not observed among non-autistic people. CONCLUSIONS: Autistic people may be at reduced risk for memory problems as they age, compared to their same-age non-autistic peers. Further studies are required to explore the association between self-reported memory challenges and memory task performance among autistic older people.

Although the electrophysiological event-related potential in face processing (e.g. N170) is widely accepted as a face-sensitivity biomarker that is deficient in children with autism spectrum disorders, the time-varying brain networks during face recognition are still awaiting further investigation. To explore the social deficits in autism spectrum disorder, especially the time-varying brain networks during face recognition, the current study analyzed the N170, cortical activity, and time-varying networks under 3 tasks (face-upright, face-inverted, and house-upright) in autism spectrum disorder and typically developing children. The results revealed a smaller N170 amplitude in autism spectrum disorder compared with typically developing, along with decreased cortical activity mainly in occipitotemporal areas. Concerning the time-varying networks, the atypically stronger information flow and brain network connections across frontal, parietal, and temporal regions in autism spectrum disorder were reported, which reveals greater effort was exerted by autism spectrum disorder to obtain comparable performance to the typically developing children, although the amplitude of N170 was still smaller than that of the typically developing children. Different brain activation states and interaction patterns of brain regions during face processing were discovered between autism spectrum disorder and typically developing. These findings shed light on the face-processing mechanisms in children with autism spectrum disorder and provide new insight for understanding the social dysfunction of autism spectrum disorder.

The current review aimed to evaluate the effectiveness of behavior-analytic procedures in increasing face mask-wearing in autistic individuals. This comes following recommended guidance during the COVID-19 pandemic. A systematic review and meta-analysis were completed of peer-reviewed and grey literature. Six databases were searched and seven studies using single-case experimental designs met the eligibility criteria which were then quality appraised. Data were extracted on participant characteristics, study design, independent and dependent variables, fidelity, generalization, maintenance, and social validity outcomes. Both the non-overlap of all pairs and Baseline Corrected TAU were used to estimate effect size. Two studies were rated strong and borderline strong quality and five were rated as adequate or below. All studies showed positive outcomes for mask-wearing, with an average of 0.92 for non-overlap of all pairs and 0.47 for Baseline Corrected Tau effect sizes. The most common and effective procedures for increasing mask-wearing were graded exposure and differential and positive reinforcement. Factors such as mode of delivery, implementer, and setting did not appear to influence study outcomes. Procedures were found to be rated as acceptable by parents and professionals in five of the studies. The existing literature on increasing face mask-wearing in autistic individuals provides promising findings to add to existing literature around increasing tolerance to medical equipment and hygiene practices in autistic populations. However, these findings are based on a small sample size, with six of the studies taking place in the United States with varying study quality.

This article traces the origin, sustenance and implications of a persistent rumour that is responsible for low measles mumps and rubella (MMR) vaccination uptake in the Somali diaspora in a number of countries across the globe. The rumour stipulates that the MMR vaccine – the silent shot – causes autism spectrum disorder (ASD). Although the association between MMR and ASD is non-causal, and various public health initiatives have promoted health information campaigns, the rumour continues to circulate in the Somali diaspora in many countries, including Sweden. This paper shows that there are valid reasons for this. The findings from this paper draw on a systematic scoping review and qualitative interview data from Sweden. The results show that the Somali community experiences higher than average rates of ASD compared to the general population. Moreover, ASD does not exist in the Somali language or their home country, is considered a Western disease that only affects Somali children in the diaspora, and is a highly stigmatised disease. Also, the Somali diaspora has had negative experiences with ASD diagnosis and care. The rumour has been sustained by the absence of an answer to their ASD fear and through active diaspora networks on social media. The network that surrounds the rumour has arguably further helped to create an epistemic community for a community whose concerns have been silenced.

PURPOSE: We explored factors predicting repeated or hazardous alcohol use among autistic and non-autistic U.S. youth ages 16 to 20 years. METHODS: Autistic (n = 94) and non-autistic (n = 92) youth completed an online survey. By design, half of each group reported past-year alcohol use. We compared drinking patterns for autistic and non-autistic youth, and within each group between abstinent or infrequent drinkers (0-1 drinking episodes in past year) versus those who drank 2 + times in past year. RESULTS: Autistic (vs. non-autistic) youth who drank did so less frequently and consumed fewer drinks per occasion. However, 15% of autistic youth who drank in the past year reported heavy episodic drinking and 9.3% screened positive for AUDIT-C hazardous drinking. For autistic youth only, a diagnosis of depression, bullying or exclusion histories were positively associated with drinking 2 + times in the past year. Autistic youth who put more effort into masking autistic traits were less likely to report drinking 2 + times in the past year. As compared to non-autistic youth, autistic participants were less likely to drink for social reasons, to conform, or to enhance experiences, but drank to cope at similar rates. CONCLUSION: Repeated and hazardous underage alcohol occur among autistic youth. Targeted prevention programs designed to address the specific drinking profiles of autistic youth are needed.

Relative Efficacy of Self-directed and Therapist-assisted Telehealth Models of a Parent-mediated Intervention for Autism: Examining Effects on Parent Intervention Fidelity, Well-being, and Program Engagement. Journal of autism and developmental disorders. 2023.

PURPOSE: Although there is growing interest in telehealth to deliver parent-mediated intervention for autistic children, empirical evaluations are limited, and little is known regarding the relative benefits of self-directed and therapist-assisted telehealth interventions. This study examined the effect of self-directed and therapist-assisted ImPACT Online on parent learning and well-being, moderators of treatment, and predictors of program engagement. METHOD: Sixty-four young autistic children and their primary caregiver participated. Children were matched on age and developmental quotient and randomly assigned to a therapist-assisted, self-directed, or resource support control group. Participants were assessed at intake, after 6 months (post), and at a 3-month follow-up. RESULTS: There was a significant treatment effect for parent learning for the therapist-assisted but not self-directed program; when analysis was limited to parents who completed the program, treatment effects were observed for both groups. There were no treatment effects for parent self-efficacy or parenting stress; however, there was an effect on parents’ perception of their child’s positive impact. Parenting stress did not moderate the effect of group on parent outcomes. Parent age, program satisfaction, and therapist assistance were all significant predictors of parent program engagement. CONCLUSION: This study supports the efficacy of therapist-assisted telehealth parent-mediated intervention for teaching parents intervention strategies to support their child’s social communication and improving their perceptions of their child’s positive impact, and suggests that self-directed programs may be beneficial for parents who fully engage with the program.

This systematic review evaluated the treatment effects of communication-focused parent-mediated interventions (CF-PMT), a form of intervention that involves therapists observing parent-child interactions and giving feedback to parents on how they can practice positive parenting strategies to prevent or reduce externalizing behaviours in children with developmental disabilities. A literature search was conducted on three electronic databases. To be included in the review, studies had to: evaluate CF-PMT where therapists give feedback after observing parent-child interactions; examine changes in externalizing behaviours amongst children with any forms of developmental disability; and adopt a randomised controlled trial study design. Fifteen studies met eligible criteria for the literature review, of those, 13 studies had available data on changes in the primary (child externalizing behaviours) and secondary outcomes (parental stress, child linguistic abilities and child social responsiveness). We found significant treatment effects for CF-PMT in reducing child externalizing behaviours (d = -.60) but not for any of the secondary outcomes. A sensitivity analysis showed a small but significant treatment effect for parental stress (d = -.18). Considerable bias was observed due to the lack of available information reported by studies on aspects measured by the Mixed Methods Appraisal Tool. Overall, we found evidence to support the benefits of complex interventions which incorporate direct parent-child observations and feedback to improve behavioural outcomes amongst children with developmental disabilities.

Although there is evidence that exposure to ground-level ozone (O(3)) may cause an increased risk of neurological disorders (e.g., autistic spectrum disorder), low-dose chronic ozone exposure and its adverse effects on the nervous system have not been fully understood. Here, we evaluated the potential neurotoxic effects of long-term exposure to environmentally relevant O(3) concentration (200 μg/m(3) via a whole-body inhalation system, 12 h/day for 5 days/week) using a susceptible mouse model of autism induced by valproic acid. Various indicators of oxidative stress, mitochondria, and synapse in the brain tissues were then measured to determine the overall damage of O(3) to the mouse brain. The results showed an aggravated risk of autism in mice offspring, which was embodied in decreased antioxidant contents, disturbed energy generation in mitochondria, as well as reduced expressions of protein kinase Mζ (PKMζ) and synaptic proteins [e.g., Synapsin 1 (SYN 1), postsynaptic density protein-95 (PSD-95)]. Overall, our study indicates that prenatal exposure to environmentally relevant O(3) may exacerbate the symptoms of autism, shedding light on possible molecular mechanisms and providing valuable insights into the pathogenesis of autism, especially concerning low-dose levels of those pollutants.

Prior evidence has suggested the alleviatory effect of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) on neuroinflammation in neurodegenerative diseases. This study primarily investigates the underlying mechanism of how the long non-coding RNA MALAT1 affects neuronal apoptosis in the hippocampus of mice with autism spectrum disorder (ASD). The findings demonstrate that CASP3 is highly expressed while MALAT1 is downregulated in the hippocampal neurons of autistic mice. MALAT1 mainly localizes within the cell nucleus and recruits DNA methyltransferases (including DNMT1, DNMT3a, and DNMT3b) to the promoter region of CASP3, promoting its methylation and further inhibiting its expression. In vitro experiments reveal that reducing MALAT1 expression promotes the expression of CASP3 and Bax while suppressing Bcl-2 expression, thereby enhancing cellular apoptosis. Conversely, increasing MALAT1 expression yields the opposite effect. Consequently, these results further confirm the role of MALAT1 in suppressing neuronal apoptosis in the hippocampus of mice with ASD through the regulation of CASP3 promoter methylation. Thus, this research unveils the significant roles of MALAT1 and CASP3 in the pathogenesis of ASD, offering new possibilities for future therapeutic interventions.

PURPOSE: Restricted and repetitive behaviours are a core feature of autism diagnoses but have not been widely studied in adulthood. This study examined the rates of and associations between repetitive behaviours and sensory sensitivity in autistic and non-autistic adults; and whether repetitive behaviours described as « stimming » impacted coping with difficulties (self-efficacy). METHODS: Diagnosed autistic (n = 182), undiagnosed autistic (n = 163) and non-autistic (n = 146) adults completed online measures of repetitive behaviours, sensory sensitivity, and self-efficacy for when able and not able to stim. RESULTS: Repetitive behaviours and sensory sensitivity correlated significantly in each group, although ratings were higher in autistic compared to non-autistic groups. When people were able to stim, no differences between the groups were observed on self-efficacy ratings. However when unable to stim, autistic people reported lower self-efficacy than non-autistic people. CONCLUSIONS: Results suggest that repetitive behaviours are significantly associate with sensory sensitivities. Rather than repetitive behaviours being viewed as negative, stimming was associated with increased self-efficacy. Results suggest that stimming may have beneficial effects. Further work is needed to better understand how repetitive behaviours and stimming manifest in adulthood, how they change over time and their effects for autistic adults.

PURPOSE: To investigate the perceptions of parents/caregivers about the impact of oral conditions on the oral health-related quality of life (OHRQoL) of children/adolescents with autism spectrum disorder (ASD) compared to the perceptions of parents/caregivers of children/adolescents without ASD. METHODS: A comparative cross-sectional study was conducted involving 80 children/adolescents with ASD three to 16 years of age matched by sex and age with 80 children/adolescents without ASD and their parents/caregivers. Clinical examinations were performed for the diagnosis of dental caries experience (DMFT/dmft), clinical consequences of untreated dental caries (PUFA/pufa), visible plaque (VPI), bleeding on probing (BPI), malocclusion and traumatic dental injury (TDI). Parents/caregivers answered a questionnaire addressing sociodemographic characteristics and the Brazilian version of the Parental-Caregiver Perceptions Questionnaire (P-CPQ), which measures OHRQoL from the perspective of parents/caregivers. Data analysis involved the Wilcoxon test, chi-squared test and Poisson regression. RESULTS: Dental caries experience impacted OHRQoL in the group with ASD regarding the total P-CPQ score (p < 0.001) as well as the "oral symptoms" (p = 0.011) and "wellbeing" (p < 0.011) domains. No differences were found between the perceptions of parents/caregivers of children/adolescents with ASD and perceptions of parents/caregivers of children/adolescents without ASD (p = 0.721). CONCLUSION: Dental caries experience can have a negative impact on the OHRQoL of children/adolescents with ASD.

BACKGROUND: When screening for autism spectrum disorders (ASD), the Autism Spectrum Quotient (AQ) is generally considered to be useful. Whether the AQ is also a suitable screener for ASD in juveniles with severe behavioral problems (SBPs) is unknown. Due to the overlap of symptoms between ASD and SBPs, particularly in juveniles low on empathy, the screening capacity of the AQ might be constrained. The aim of the present study was to investigate whether (comorbid) SBPs affect the screening capacity of the AQ. The hypothesis is that male juveniles with SBPs – but without a diagnosis of ASD – will score higher than male juveniles without both SBPs and ASD. METHOD: The AQ was completed by 216 male juveniles aged 15-18 years treated at an outpatient department of child and adolescent psychiatry. The 216 participants were categorized into four groups according to a clinical diagnosis of ASD and SBPs (defined as disruptive behavior disorder and/or delinquent behavior). Using multinomial logistic regression, we investigated whether the four identified groups, based on a diagnosis of ASD and SBPs, scored differently for the total score and subscales of the AQ. RESULTS: Participants in the group with ASD (ASD(+)) but without SBPs (SBP(-)) were more likely to report higher levels of autistic traits than the reference group without both ASD and SBPs (ASD(-)SBP(-)), except for the subscale on attention to detail (ASD(+)SBP(-) OR = 1.04; 95%CI = 0.98-1.11). Participants in the group with both ASD and SBPs were more likely to report higher levels for the total AQ score (ASD(+)SBP(+) OR = 1.03; 95%CI = 1.00-1.05) and the communication subscale of the AQ (ASD(+)SBP(+) OR = 1.18; 95%CI = 1.07-1.31) than the reference group without both ASD and SBPs. CONCLUSION: In outpatient male juveniles, SBPs do not affect the screening capacity of the AQ for autistic traits. In spite of the well-known overlap of symptoms between ASD and SBPs, male juveniles with SBPs but without a diagnosis of ASD do not score higher on the AQ than male juveniles without SBPs and without a diagnosis of ASD.

The Selective Social Attention task in children with autism spectrum disorder: Results from the Autism Biomarkers Consortium for Clinical Trials (ABC-CT) feasibility study. Autism research : official journal of the International Society for Autism Research. 2023.

The Selective Social Attention (SSA) task is a brief eye-tracking task involving experimental conditions varying along socio-communicative axes. Traditionally the SSA has been used to probe socially-specific attentional patterns in infants and toddlers who develop autism spectrum disorder (ASD). This current work extends these findings to preschool and school-age children. Children 4- to 12-years-old with ASD (N = 23) and a typically-developing comparison group (TD; N = 25) completed the SSA task as well as standardized clinical assessments. Linear mixed models examined group and condition effects on two outcome variables: percent of time spent looking at the scene relative to scene presentation time (%Valid), and percent of time looking at the face relative to time spent looking at the scene (%Face). Age and IQ were included as covariates. Outcome variables’ relationships to clinical data were assessed via correlation analysis. The ASD group, compared to the TD group, looked less at the scene and focused less on the actress’ face during the most socially-engaging experimental conditions. Additionally, within the ASD group, %Face negatively correlated with SRS total T-scores with a particularly strong negative correlation with the Autistic Mannerism subscale T-score. These results highlight the extensibility of the SSA to older children with ASD, including replication of between-group differences previously seen in infants and toddlers, as well as its ability to capture meaningful clinical variation within the autism spectrum across a wide developmental span inclusive of preschool and school-aged children. The properties suggest that the SSA may have broad potential as a biomarker for ASD.

21. Stern SC. Using Popular Media to Change Attitudes and Bolster Knowledge About Autism Spectrum Disorder. Journal of autism and developmental disorders. 2023.

This research investigated the impact popular novels have on knowledge about and attitudes towards Autism Spectrum Disorder (ASD), compared to that of traditional college textbooks. Study 1 found that participants in the novel condition chose fewer correct and fewer incorrect responses to questions about ASD. Participants did not differ in their desired social distance from individuals with ASD. Study 2 found that participants in the novel and textbook conditions both showed the same amount of learning, with higher scores on the post-test assessment of knowledge than the pre-test. Participants in the novel condition showed significant improvement in their attitudes towards individuals with ASD after reading, while those in the textbook condition showed more negative attitudes after reading the textbook chapter. These findings add to our understanding of the potential of popular fiction to impact consumers’ knowledge about ASD while improving our attitudes towards individuals with ASD. These findings also raise concerns about traditional educational material used to teach about ASD.

BACKGROUND: Children and adolescents with intellectual and developmental disabilities (I/DD), including autism spectrum disorder, benefit from a variety of specialized interventions. However, there are barriers that impact families’ ability to access such services for their children. While not intended as a replacement for individualized or group-based interventions, educational classes may be an option in providing supplemental resources and support to families of individuals with I/DD. This study was a programme evaluation that examined the feasibility and acceptability of a Caregiver Education Program that was created in an outpatient specialty clinic of an academic medical centre, designed to provide educational information on a variety of topics relevant to children and adolescents with I/DD (e.g., toilet training, understanding behaviour and managing anxiety). METHOD: The review included 1027 participants from 40 classes led by licensed clinicians, trainees, and/or experienced caregivers. Classes occurred approximately one time per month over the course of three-and-a-half years and targeted caregivers of children and adolescents with I/DD and community-based professionals in the field of I/DD. Participants were able to attend one or multiple classes, based on their interest in the given topic. Participants were asked to complete post-training surveys at the end of each session as part of ongoing programme evaluation. RESULTS: Participants reported a high level of satisfaction and increased knowledge as a result of participating in classes, and higher knowledge gained and higher satisfaction for in-person classes compared to virtual classes. CONCLUSIONS: This programme is one model of education delivery with high acceptability and feasibility, designed to support families and increase access to information beyond specialized interventions. Future directions include improving the model of programme data collection, examination of the programme’s generalization to practice and to other communities, and an emphasis on culturally responsive curricula.

Fragile X syndrome (FXS) is one of the most common inherited causes of intellectual disabilities. While there is currently no cure for FXS, EEG is considered an important method to investigate the pathophysiology and evaluate behavioral and cognitive treatments. We conducted EEG microstate analysis to investigate resting brain dynamics in FXS participants. Resting-state recordings from 70 FXS participants and 71 chronological age-matched typically developing control (TDC) participants were used to derive microstates via modified k-means clustering. The occurrence, mean global field power (GFP), and global explained variance (GEV) of microstate C were significantly higher in the FXS group compared to the TDC group. The mean GFP was significantly negatively correlated with non-verbal IQ (NVIQ) in the FXS group, where lower NVIQ scores were associated with greater GFP. In addition, the occurrence, mean duration, mean GFP, and GEV of microstate D were significantly greater in the FXS group than the TDC group. The mean GFP and occurrence of microstate D were also correlated with individual alpha frequencies in the FXS group, where lower IAF frequencies accompanied greater microstate GFP and occurrence. Alterations in microstates C and D may be related to the two well-established cognitive characteristics of FXS, intellectual disabilities and attention impairments, suggesting that microstate parameters could serve as markers to study cognitive impairments and evaluate treatment outcomes in this population. Slowing of the alpha peak frequency and its correlation to microstate D parameters may suggest changes in thalamocortical dynamics in FXS, which could be specifically related to attention control.

PURPOSE: Disorders on the autism spectrum have characteristics that can manifest as difficulties with communication, executive functioning, daily living, and more. These challenges can be mitigated with early identification. However, diagnostic criteria has changed from DSM-IV to DSM-5, which can make diagnosing a disorder on the autism spectrum complex. We evaluated machine learning to classify individuals as having one of three disorders of the autism spectrum under DSM-IV, or as non-spectrum. METHODS: We employed machine learning to analyze retrospective data from 38,560 individuals. Inputs encompassed clinical, demographic, and assessment data. RESULTS: The algorithm achieved AUROCs ranging from 0.863 to 0.980. The model correctly classified 80.5% individuals; 12.6% of individuals from this dataset were misclassified with another disorder on the autism spectrum. CONCLUSION: Machine learning can classify individuals as having a disorder on the autism spectrum or as non-spectrum using minimal data inputs.

Autism is increasingly viewed as an expression of neurodiversity deserving accommodation, rather than merely as a disorder in need of remediation or even prevention. This reconceptualization has inspired calls to broaden the ethical debate on early autism care beyond matters of efficient screenings and effective interventions. We conducted 14 in-depth interviews with 26 parents of infants at an increased likelihood for autism (siblings, preterms and children with persistent feeding difficulties) to understand which benefits and risks these parents see for the implementation of a systematic, early autism detection program in our region. With this study, we aim to contribute empirically to the ethical debate on good and just early autism care in the age of neurodiversity. Data were analyzed according to the QUAGOL-methodology. Three main themes emerged from our analysis. In their evaluation of early autism detection, parents discussed how a diagnosis helps gain a different perspective fostering understanding and recognition for both child and parent. Second, a diagnosis supports parents in adjusting their parenting practices, to justify this deviation from « normal » parenting and to strive for such adjusted environments beyond the nuclear family. Third, an autism diagnosis induces ambiguities parents need to navigate, involving questions on whether and when to mobilize the diagnostic label and which language to use to talk about autism. We discuss the complex position of parents of a (potentially) autistic child in terms of moving back and forth across the ab/normal binary and describe implications for the ethical debate on early autism detection.

26. Wilson AC, Gullon-Scott F. Social Anxiety in Autistic People: Does the Clark and Wells Model fit?. Journal of autism and developmental disorders. 2023.

PURPOSE: Cognitive behaviour therapy based on the Clark and Wells (1995) model is a first-line treatment for neurotypical people seeking support for social anxiety. While autistic people frequently report high social anxiety, it is unclear how appropriate the model is for this population. METHODS: Over 300 autistic and non-autistic adults completed an online survey measuring key variables of the Clark and Wells model (socially-related negative thoughts, safety behaviours, self-focused attention). Using multiple regression and structural equation modelling, we assessed whether these variables accounted for the link between autism and social fears. RESULTS: In multiple regression, autistic people experienced greater social fears than expected based on Clark and Wells variables, and safety behaviours were less predictive of social fears in autistic people. In structural equation modelling, Clark and Wells variables only mediated half the link between autistic traits and social fears. In exploratory analysis, we found that distress relating to uncertainty was an additional variable that needed to be taken into consideration in the relationship between autistic traits and social fears. CONCLUSION: The Clark and Wells variables were relevant in autism, but did not fully explain elevated social fears in autistic people, which suggests that other factors are also important in accounting for social anxiety in autistic people. This means that therapy informed by the model may not be optimal for autistic people. We recommend further research developing adapted therapy for social anxiety in autistic people.
