Autistic burnout has been talked about by autistic adults for some time on blogs and in social media. Now, research describes fatigue, exhaustion and other related symptoms experienced by autistic people. We need new ways to help identify autistic burnout. In this study, we tested a new questionnaire called the AASPIRE Autistic Burnout Measure, and we investigated things that are linked to worse autistic burnout. We also trialled a group of Autistic Burnout Severity Items that we made. Working with an autistic researcher, we made the Autistic Burnout Severity Items based on published definitions of autistic burnout. Autistic adults (n = 141) who had experienced autistic burnout completed an online survey. We found that autistic burnout was connected to masking and depression. The Autistic Burnout Measure tool was associated with depression but not with masking. It was not very accurate in telling apart participants who were currently experiencing burnout versus those who were reporting on their past experience. The Autistic Burnout Severity Items might have problems with subscales adding together to measure autistic burnout. More work is needed on how to measure autistic burnout. Our research and other recent studies show autistic people experience a combination of exhaustion, withdrawal and problems with their concentration and thinking. Burnout seems to be linked to the stress experienced by autistic people in their daily lives. We need more research to understand the difference between autistic burnout and other conditions and experiences. We need to develop assessment tools that can help identify this burnout.

Autistic burnout is something autistic people have been talking about for a while (see #AutBurnout and #AutisticBurnout on social media). Recently, researchers published two different definitions of autistic burnout. We wanted to test these definitions. We wanted to confirm the duration and frequency of autistic burnout. That is, how long and how often do people get autistic burnout? We surveyed 141 autistic adults who had autistic burnout. We used descriptive statistics, content analysis and reflexive thematic analysis to analyse the survey responses. Autistic adults strongly agreed with the definition published by Higgins et al. How long and how often people get autistic burnout was not clear. Participants told us they have both short and long episodes. Participants told us that autistic burnout leads to exhaustion. They needed to withdraw from being with other people. They needed to stay away from autism unfriendly places. Many had been misdiagnosed as having depression, anxiety, bipolar disorder, borderline personality disorder or other conditions. We need increased awareness of autistic burnout. Autistic people need more help. More research is needed, we need to have bigger studies to understand autistic burnout.

Profiles of autism characteristics in thirteen genetic syndromes: a machine learning approach. Molecular autism. 2023; 14(1): 3.

BACKGROUND: Phenotypic studies have identified distinct patterns of autistic characteristics in genetic syndromes associated with intellectual disability (ID), leading to diagnostic uncertainty and compromised access to autism-related support. Previous research has tended to include small samples and diverse measures, which limits the generalisability of findings. In this study, we generated detailed profiles of autistic characteristics in a large sample of > 1500 individuals with rare genetic syndromes. METHODS: Profiles of autistic characteristics based on the Social Communication Questionnaire (SCQ) scores were generated for thirteen genetic syndrome groups (Angelman n = 154, Cri du Chat n = 75, Cornelia de Lange n = 199, fragile X n = 297, Prader-Willi n = 278, Lowe n = 89, Smith-Magenis n = 54, Down n = 135, Sotos n = 40, Rubinstein-Taybi n = 102, 1p36 deletion n = 41, tuberous sclerosis complex n = 83 and Phelan-McDermid n = 35 syndromes). It was hypothesised that each syndrome group would evidence a degree of specificity in autistic characteristics. To test this hypothesis, a classification algorithm via support vector machine (SVM) learning was applied to scores from over 1500 individuals diagnosed with one of the thirteen genetic syndromes and autistic individuals who did not have a known genetic syndrome (ASD; n = 254). Self-help skills were included as an additional predictor. RESULTS: Genetic syndromes were associated with different but overlapping autism-related profiles, indicated by the substantial accuracy of the entire, multiclass SVM model (55% correctly classified individuals). Syndrome groups such as Angelman, fragile X, Prader-Willi, Rubinstein-Taybi and Cornelia de Lange showed greater phenotypic specificity than groups such as Cri du Chat, Lowe, Smith-Magenis, tuberous sclerosis complex, Sotos and Phelan-McDermid. The inclusion of the ASD reference group and self-help skills did not change the model accuracy. LIMITATIONS: The key limitations of our study include a cross-sectional design, reliance on a screening tool which focuses primarily on social communication skills and imbalanced sample size across syndrome groups. CONCLUSIONS: These findings replicate and extend previous work, demonstrating syndrome-specific profiles of autistic characteristics in people with genetic syndromes compared to autistic individuals without a genetic syndrome. This work calls for greater precision of assessment of autistic characteristics in individuals with genetic syndromes associated with ID.

4. Brunt S, Nevill R, Mazurek MO. Associations Among Autism Symptom Domains and Facets of Caregiver Strain. Journal of autism and developmental disorders. 2023.

Parents of children with autism spectrum disorder (ASD) often experience elevated levels of caregiver strain (CGS). Few studies have examined the relationship between core ASD symptoms and each facet of CGS: objective, subjective internalized, and subjective externalized strain. The predictive effect of core and associated features of ASD on CGS facets were investigated, while also exploring the moderating effect of age. Atypical behaviors and behavior problems were the strongest predictors of all types of caregiver strain. For younger children, more repetitive behaviors predicted higher externalized strain, yet the opposite was true for parents of adolescents. Given that caregiver strain impacts parents’ service utilization patterns, future research should focus on strategies to support parents in reducing caregiver strain.

Longitudinal neurobehavioral profiles in children and young adults with PTEN hamartoma tumor syndrome and reliable methods for assessing neurobehavioral change. Journal of neurodevelopmental disorders. 2023; 15(1): 3.

BACKGROUND: Individuals with PTEN hamartoma tumor syndrome (PHTS) demonstrate a distinct neurobehavioral profile suggesting primary disruption of frontal lobe symptoms, with more severe cognitive deficits in those with associated autism spectrum disorder (ASD) that extend to other areas of neurobehavioral function as well (e.g., adaptive behavior, sensory deficits). The current study sought to characterize longitudinal neurobehavioral profiles in individuals with PHTS who completed serial assessments (2-3 evaluations) over a 2-year time period. METHODS: Comprehensive neurobehavioral evaluations were conducted on 92 participants (age range 6-21) with PHTS and/or ASD. Spaghetti plots and linear mixed effects models were used to visualize the individual patient profiles and group trends and examine the group differences in cognitive/behavioral test scores over time. Practice-adjusted reliable change indices (RCIs) and standardized regression-based change scores (SRBs) were calculated for those measures in the battery with adequate sample sizes and test-retest reliabilities for future use in assessing neurobehavioral change in children and young adults with PHTS. RESULTS: Wide individual differences were observed at baseline across all measures. Encouragingly, baseline differences between patient groups persisted at the same magnitude over a 2-year time period with no differences in longitudinal neurobehavioral profiles within any one group. Test-retest reliabilities were generally high, ranging from 0.62 to 0.97, and group mean change from baseline to 12 months was small (range - 3.8 to 3.7). A Microsoft Excel calculator was created that clinicians and researchers can use to automatically calculate RCI and SRB thresholds at both 80% and 90% confidence intervals using test scores from a given child or young adult with PHTS. CONCLUSIONS: Our results suggest that the neurobehavioral phenotypes observed in individuals with PHTS remain relatively stable over time, even in those with ASD. The RCIs and SRBs provided can be used in future research to examine patient outcomes at the individual level as well as to detect negative deviations from the expected trajectory that can be used to inform intervention strategies.

BYLEMANS, T., et al. Mentalizing and narrative coherence in autistic adults: Cerebellar sequencing and prediction. NEUROSCI BIOBEHAV REV, 2022. – This review focuses on autistic adults and serves 4 purposes: (1) providing an overview of their difficulties regarding mentalizing (understanding others’ mental states) and narrative coherence (structured storytelling), (2) highlighting the relations between both skills by examining behavioral observations and shared neural substrates, (3) providing an integrated perspective regarding novel diagnostic tools and support services, and (4) raising awareness of adult autism. We suggest that mentalizing and narrative coherence are related at the behavioral level and neural level. In addition to the traditional mentalizing network, the cerebellum probably serves as an important hub in shared cerebral networks implicated in mentalizing and narrative coherence. Future autism research and support services should tackle new questions within a framework of social cerebellar (dys)functioning.

Programmatic cost assessment of clinical interventions can inform future dissemination and implementation efforts. We conducted a randomized trial of Project ImPACT (Improving Parents As Communication Teachers) in which community early intervention (EI) providers coached caregivers in techniques to improve young children’s social communication skills. We estimated implementation and intervention costs while demonstrating an application of Time-Driven Activity-Based Costing (TDABC). We defined Project ImPACT implementation and intervention as processes that can be broken down successively into a set of procedures. We created process maps for both implementation and intervention delivery. We determined resource use and costs, per unit procedure in the first year of the program, from a payer perspective. We estimated total implementation cost per clinician and per site, intervention cost per child, and provided estimates of total hours spent and associated costs for implementation strategies, intervention activities and their detailed procedures. Total implementation cost was $43,509 per clinic and $14,503 per clinician. Clinician time (60%) and coach time (12%) were the most expensive personnel resources. Implementation coordination and monitoring (47%), ongoing consultation (26%) and clinician training (19%) comprised most of the implementation cost, followed by fidelity assessment (7%), and stakeholder engagement (1%). Per-child intervention costs were $2619 and $9650, respectively, at a dose of one hour per week and four hours per week Project ImPACT. Clinician and clinic leader time accounted for 98% of per child intervention costs. Highest cost intervention activity was ImPACT delivery to parents (89%) followed by assessment for child’s ImPACT eligibility (10%). The findings can be used to inform funding and policy decision-making to enhance early intervention options for young children with autism. Uncompensated time costs of clinicians are large which raises practical and ethical concerns and should be considered in planning of implementation initiatives. In program budgeting, decisionmakers should anticipate resource needs for coordination and monitoring activities. TDABC may encourage researchers to assess costs more systematically, relying on process mapping and gathering prospective data on resource use and costs concurrently with their collection of other trial data.

Lymphocytic Extracellular Signal Regulated Kinase Dysregulation in Autism Spectrum Disorder. Journal of the American Academy of Child and Adolescent Psychiatry. 2023.

OBJECTIVE: Extracellular signal-regulated kinase (ERK1/2) is a conserved central intracellular signaling cascade involved in many aspects of neuronal development and plasticity. Converging evidence support investigation of ERK1/2 activity in autism spectrum disorder (ASD). We previously reported enhanced baseline lymphocytic ERK1/2 activation in autism, and now we extend our work to investigate the early phase kinetics of lymphocytic ERK1/2 activation in idiopathic ASD. METHOD: Study participants included 67 individuals with ASD (3-25 years old), 65 age- and sex-matched typical developing control (TDC) subjects, and 36 age-, sex-, and IQ-matched developmental disability controls (DDC) matched to those with ASD and IQ<90. We completed an additional analysis comparing results from ASD, TDC, and DDC groups with data from 37 individuals with fragile X syndrome (FXS). All subjects had blood lymphocyte samples analyzed by flow cytometry following stimulation with phorbol ester and sequentially analyzed for ERK1/2 activation (phosphorylation) at several time points. RESULTS: The ASD group (M = 5.81 minutes; SD = 1.5) had a significantly lower (more rapid) mean ERK1/2 T(1/2) activation value than both the DDC group (M = 6.78 minutes; SD = 1.6; p=0.00078) and TDC group (M = 6.4 minutes; SD = 1.5; p=0.025). More rapid ERK1/2 T(1/2) activation times did correlate with increased social impairment across all study groups including the ASD cohort. Differences in ERK1/2 T(1/2) activation were more pronounced in younger than older individuals in the primary analysis. The ASD group additionally had more rapid activation times than the FXS subject group and the FXS group activation kinetics did not differ from TDC and DDC subject groups. CONCLUSION: Our findings indicate that lymphocytic ERK1/2 activation kinetics are dysregulated in persons with ASD, marked by more rapid early phase activation. Group differences in ERK1/2 activation kinetics appear driven by findings from the youngest children analyzed. DIVERSITY & INCLUSION STATEMENT: We worked to ensure sex and gender balance in the recruitment of human participants. We actively worked to promote sex and gender balance in our author group. The author list of this paper includes contributors from the location and/or community where the research was conducted who participated in the data collection, design, analysis, and/or interpretation of the work.

10. Falck-Ytter T, Kleberg JL, Portugal AM, Thorup E. Social Attention: Developmental Foundations and Relevance for Autism Spectrum Disorder. Biological psychiatry. 2022.

The use of the term « social attention » (SA) in the cognitive neuroscience and developmental psychopathology literature has increased exponentially in recent years, in part motivated by the aim to understand the early development of autism spectrum disorder (ASD). Unfortunately, theoretical discussions around the term have lagged behind its various uses. Here, we evaluate SA through a review of key candidate SA phenotypes emerging early in life, from newborn gaze cueing and preference for face-like configurations to later emerging skills such as joint attention. We argue that most of the considered SA phenotypes are unlikely to represent unique socioattentional processes and instead have to be understood in the broader context of bottom-up and emerging top-down (domain-general) attention. Some types of SA behaviors (e.g., initiation of joint attention) are linked to the early development of ASD, but this may reflect differences in social motivation rather than attention per se. Several SA candidates are not linked to ASD early in life, including the ones that may represent uniquely socioattentional processes (e.g., orienting to faces, predicting others’ manual action goals). Although SA may be a useful superordinate category under which one can organize certain research questions, the widespread use of the term without proper definition is problematic. Characterizing gaze patterns and visual attention in social contexts in infants at elevated likelihood of ASD may facilitate early detection, but conceptual clarity regarding the underlying processes at play is needed to sharpen research questions and identify potential targets for early intervention.

Psychiatric Comorbidities in Children and Adolescents with High-Functioning Autism Spectrum Disorder: A Study on Prevalence, Distribution and Clinical Features in an Italian Sample. Journal of clinical medicine. 2023; 12(2).

This study investigated the prevalence and distribution of psychiatric comorbidities in a group of 472 children and adolescents with ASD aged 3-18 years. We examined differences in age, sex, IQ, adaptive skills, and ASD symptom severity by comparing participants with ASD (ASD group) with participants with ASD and a psychiatric disorder (ASD/PSY group). Overall, 32.2% of participants had a comorbid psychiatric condition. Attention deficit/hyperactivity disorder (ADHD) was the most frequent diagnosis among preschoolers (20.4%); among school-age children, ADHD and anxiety/obsessive-compulsive disorders were the most frequent conditions (21% and 10.6%, respectively); finally, adolescents exhibit higher prevalence of anxiety/obsessive-compulsive disorders (21.8%). The ASD/PSY group showed a higher percentage of males, they were older and showed lower adaptive skills than the group with ASD; moreover, their mothers exhibited higher stress levels than mothers of participants in the ASD group. The comparison between age groups in participants within ASD/PSY group revealed that preschoolers had lower IQ than school-age children and adolescents, and worse adaptive skills, more repetitive behaviors, and restricted interests than adolescents. This study highlights the importance of an accurate diagnosis of psychiatric comorbidities in children and adolescents with ASD, also considering individual and family impairment.

12. Hamama L. Perceived Social Support, Normalization, and Subjective Well-Being Among Family Members of a Child with Autism Spectrum Disorder. Journal of autism and developmental disorders. 2023.

The experience of family members of children with autism spectrum disorder (ASD) is not uniform. This study focused on mothers of a child with ASD (Study 1) and typically developing siblings (TDSs) during their emerging adulthood (Study 2). Similarities and differences were explored regarding a proposed model examining the paths of perceived social support (PSS) and normalization (a coping strategy) with subjective well-being: satisfaction with life (SWL) and positive affect (PA). Similarities were found in the paths between PSS, normalization, and SWL, in mothers and TDSs, but differences emerged regarding PA. These findings highlight the importance of PSS as a resource that contributes to normalization and SWL. Professional awareness of family members’ PSS and their engagement in normalization is needed.

Family coaggregation of type 1 diabetes mellitus, major depressive disorder, attention-deficiency hyperactivity disorder and autism spectrum disorder in affected families: a nationwide study. Acta diabetologica. 2023.

AIMS: This study aimed to examine the risk of T1D, major depressive disorder (MDD), attention-deficiency hyperactivity disorder (ADHD), and autism spectrum disorder (ASD), in first-degree relatives (FDRs) of patients with T1D. METHODS: We enrolled 24,555 FDRs of individuals with T1D and 1:4 matched controls (N = 98,220) based on age and sex using data from the Taiwan National Health Insurance Research Database between 2001 and 2011. Poisson regression analyses were performed to estimate the risks of MDD, attention-deficiency hyperactivity disorder (ADHD), and autism spectrum disorder among the FDRs. Finally, we assessed the impact of DKA in the familial coaggregation. RESULTS: After adjusting for demographic characteristics, FDRs of individuals with T1D had higher risk of T1D (reported as relative risk with 95% confidence interval: 46.07, 33.36-63.63) and MDD (1.17, 1.04-1.32) than controls. Stratified by sex, female FDRs had increased risk of MDD (1.30, 1.13-1.51), while male FDRs had increased risk of ADHD (1.21, 1.01-1.44). Stratified by kinship, parents of individuals with T1D had increased risk of MDD (1.24, 1.06-1.44); offspring of individuals with T1D had increased risk of ADHD (1.41, 1.11-1.79). Importantly, FDRs of individuals with T1D and DKA had higher risk of MDD (1.35, 1.11-1.64) and ADHD (1.40, 1.07-1.82) than controls; however, such risks were not observed in FDRs of individuals with T1D but without DKA. CONCLUSIONS: The individual risks of T1D, MDD, and ADHD were increased in families that included patients with T1D, and DKA might play a role in such coaggregation with MDD and ADHD. Future studies are warranted to investigate the underlying mechanisms.

Comparing sensory processing in children with Down syndrome to a mental age matched sample of children with autism, other developmental disabilities, and typically developing children. Research in developmental disabilities. 2023; 134: 104421.

BACKGROUND: Atypical sensory processing impacts children with intellectual and developmental disabilities (IDD). Research has focused on SP in individuals with autism spectrum disorder (ASD); comparatively, little has been written regarding individuals with Down syndrome (DS) and IDDs. AIMS: We compared patterns of sensory processing in children with DS to children with ASD, other IDDs, and typically developing (TD) peers examining the relationship among different sensory processing measures. METHODS AND PROCEDURES: We analyzed cross-sectional data using two caregiver questionnaires (SP, SEQ) and one observational measure (SPA). Groups were compared on three sensory processing patterns: hyporesponsiveness; hyperresponsiveness; and sensory interests, repetitions, and seeking (SIRS) via ANOVA. We assessed concordance through correlations. OUTCOMES AND RESULTS: Children with DS, IDD, and ASD demonstrated more atypical sensory processing behaviors than TD peers. Children with ASD exhibited the most atypical responses across all measures, significantly more than DS children on all but one subscale. The IDD and DS groups differed on several measures. Measurement concordance was higher between caregiver-report versus observational assessment. CONCLUSIONS AND IMPLICATIONS: Differences between three clinical groups indicate that sensory processing features may differ across clinical populations regardless of cognitive functioning. Lower concordance between caregiver-report and observation measures highlights the need to understand sensory processing expression across different tasks and environments.

OBJECTIVES: This study examined the validity of the Childhood Autism Rating Scale, Second Edition (CARS-2) compared with the Autism Diagnostic Observation Schedule, Second Edition (ADOS-2) in identifying autism spectrum disorder (ASD). METHODS: A total of 237 children were tested using both the CARS-2 and ADOS-2. We examined the correlation using Pearson’s correlation analysis. In addition, we used a receiver operating characteristic graph to determine the optimal standard version of the CARS-2 (CARS2-ST) cutoff score for ASD diagnosis using the ADOS-2. RESULTS: The concurrent validity of the CARS2-ST was demonstrated by a significant correlation with the ADOS-2 (r=0.864, p<0.001). The optimal CARS2-ST cutoff scores were 30 and 28.5 for identifying autism and autism spectrum, respectively, based on the ADOS-2. CONCLUSION: We suggest a newly derived CARS2-ST cutoff score of 28.5 for screening ASD and providing early intervention.

OBJECTIVES: Regression, while not a core symptom of autism spectrum disorder (ASD), has been suggested to be a distinct subtype by previous studies. Therefore, this study aimed to explore the prevalence and clinical differences between those with and without regression in children with ASD. METHODS: This study includes data from toddlers and young children aged 2-7 years acquired from other projects at Seoul National University Bundang Hospital. The presence and characteristics of regression were explored using question items #11-28 from the Autism Diagnostic Interview-Revised. Chi-square and independent t-tests were used to compare various clinical measurements such as autistic symptoms, adaptative behavior, intelligence, and perinatal factors. RESULTS: Data from 1438 young children (1020 with ASD) were analyzed. The overall prevalence rate of regression, which was mainly related to language-related skills, was 10.2% in the ASD group, with an onset age of 24 months. Regarding clinical characteristics, patients with ASD and regression experienced ASD symptoms, especially restricted and repetitive interests and behaviors, with greater severity than those without regression. Furthermore, there were significant associations between regression and hypertension/placenta previa. CONCLUSION: In-depth surveillance and proactive interventions targeted at young children with ASD and regression should focus on autistic symptoms and other areas of functioning.

This study examined the concordance between accelerometry-measured and self-reported physical activity (PA) and sedentary time in adults with autism. Twenty-four participants wore an ActiGraph GT3X + accelerometer for seven consecutive days and completed the International Physical Activity Questionnaire-Short Form (IPAQ-SF) on the last day of their study participation. Bland-Altman plots assessed the magnitude of agreement between the two measures. Nearly 80% of the participants accumulated the recommended ≥ 150 min of moderate to vigorous PA (MVPA)/week, but were also sedentary for over nine hours/day according to accelerometry data. Findings showed that adults with autism tended to overreport MVPA (b = 1.606, p < 0.01) and underreport sedentary time (b = 1.161, p = 0.03) via the IPAQ-SF, as compared to objective measurements.

This study investigated the role of resilience as a mediator and the place of residence as a moderator of parenting stress and parental burnout. The Parenting Stress Index-Short Form, Parental Burnout Assessment, and Connor-Davidson Resilience Scale were administered to 249 Chinese parents of children with ASD (M = 33.95 years, SD = 7.6). Results show that resilience partially mediates the relation between parenting stress and parental burnout. Besides, both the effect of parenting stress on parental burnout and the mediating effect of resilience are moderated by rural/urban residence. This study highlights parenting stress is a risk factor for parental burnout and resilience is the potential mechanism underlying this relation. These findings provide implications for family services for parents of children with ASD.

Autistic people’s perceptions of their interactions with criminal justice professionals are predominantly negative; however, little is known about the state of interactions on a global scale. To further understanding, a comprehensive stakeholder questionnaire was created. Aspects of reliability and validity including evidence for test content and internal structure were gathered using expert reviews, cognitive interviewing, pilot data collection, and a larger data collection effort (N = 1618). Data was gathered from the autism community through perspectives of parents/caregivers as well as from self-reported autistic adults. Criminal justice professionals included law enforcement officers, corrections professionals, probation and parole officers, forensic psychologists and legal professionals. The scale development process was detailed in order to sufficiently document the initial psychometric evidence and share the steps taken to gain diverse stakeholder input. This study is a critical first step in generating further information to facilitate policy and program development with wide applicability.

PURPOSE: Autistic children with limited spoken language ability (LSLA) often do not respond to traditional interventions, reducing their social inclusion. It is essential to identify effective interventions, and sensitive measures to track their intervention response. METHODS: Using data from an RCT comparing music-mediated and play-based interventions, we investigated the impact of spoken language ability on outcomes, and measured response to intervention through natural language sample measures. RESULTS: Children with lower verbal IQ, relative to higher verbal IQ, made some greater gains over the course of music-mediated intervention. Natural language samples were helpful in characterizing communication and tracking change. CONCLUSION: Music-mediated interventions hold promise as effective interventions for autistic children with LSLA. Natural language samples are robust in characterizing this subgroup.

Following the published behavioral and cognitive results of this single-blind parallel sham-controlled randomized clinical trial, the current study aimed to explore the impact of intermittent theta burst stimulation (iTBS), a variant of excitatory transcranial magnetic stimulation, over the bilateral posterior superior temporal sulci (pSTS) on white matter macro/microstructure in intellectually able children and adolescents with autism. Participants were randomized and blindly received active or sham iTBS for 4 weeks (the single-blind sham-controlled phase). Then, all participants continued to receive active iTBS for another 4 weeks (the open-label phase). The clinical results were published elsewhere. Here, we present diffusion magnetic resonance imaging data on potential changes in white matter measures after iTBS. Twenty-two participants in Active-Active group and 27 participants in Sham-Active group underwent multi-shell high angular resolution diffusion imaging (64-direction for b = 2000 & 1000 s/mm(2), respectively) at baseline, week 4, and week 8. With longitudinal fixel-based analysis, we found no white matter changes following iTBS from baseline to week 4 (a null treatment by time interaction and a null within-group paired comparison in the Active-Active group), nor from baseline to week 8 (null within-group paired comparisons in both Active-Active and Sham-Active groups). As for the brain-symptoms relationship, we did not find baseline white matter metrics associated with symptom changes at week 4 in either group. Our results raise the question of what the minimal cumulative stimulation dose required to induce the white matter plasticity is.

Effects of a Parenting Intervention for Emotional and Behavioral Problems in Young Autistic Children Under Conditions of Enhanced Uncertainty: Two-Year Follow-up of a Pilot Randomized Controlled Trial Cohort (ASTAR) During the United Kingdom COVID-19 Pandemic. Journal of the American Academy of Child and Adolescent Psychiatry. 2023.

OBJECTIVE: Most young autistic children display emotional and behavioral problems (EBPs). There is evidence that behavioral parenting interventions (BPIs) reduce these. The COVID-19 pandemic and associated lockdowns can be seen as a natural experiment to test the longer-term effect of BPIs under conditions of increased uncertainty. METHOD: Opportunistic follow-up (n = 49) of a pilot randomized controlled trial (RCT) cohort (n = 62 autistic children aged 6-11 years; originally randomized to a 12-week group BPI [Predictive Parenting; n = 31] or an attention control [Psychoeducation; n = 31]) was conducted during COVID-19-related lockdowns. Measures of parent-reported child irritability and parenting stress were collected at 3 time points (baseline: mean age = 6.7 years; primary endpoint: mean age = 7.1 years, ∼5 months after randomization; and COVID-19 follow-up: mean age = 8.8 years, ∼2 years after randomization). We tested the magnitude of intervention effects using point estimates of differences in child irritability and parenting stress between arms at primary endpoint and COVID-19 follow-up, covarying for baseline scores. We used area under the curve (AUC) analyses to obtain overall estimates of the average intervention effect across all 3 timepoints. Semi-structured qualitative interviews were conducted with a subsample of parents (n = 18). RESULTS: A small but significant intervention effect was found from baseline to COVID-19 follow-up in favor of Predictive Parenting on parent-reported child irritability (d = -0.33, 95% CI = -0.65, -0.01) and parenting stress (d = -0.31, 95% CI = -0.59, -0.03). No overall mean intervention effect for these measures as estimated by the AUC analyses (which takes into account the nonsignificant effect at primary endpoint) was found. Interview feedback on the both interventions was positive, and parents reported using strategies from Predictive Parenting during COVID-19-related restrictions. CONCLUSION: This opportunistic follow-up study at a time of stress indicates the need for careful consideration of how and when to measure the effects of BPIs in autistic child populations. Future trials should consider both the most appropriate endpoint and in what context effects may be more likely to be seen.

This study investigated how emotional valence of a perceived emotional state impacted performance on the Reading the Mind in the Eyes task (RMET) in adolescents with autism spectrum disorder (ASD) and typically developing (TD) controls. Valence of items on the RMET, Adult (RMET-A) and Child (RMET-C) versions, was first classified in a survey of 113 medical students. Adolescents with ASD (N = 33) and TD adolescents (N = 30) were administered both RMET versions. Individuals with ASD made more errors than TD controls on positive and negative, but not neutral, valence items. The difference in performance was accentuated on the RMET-A compared to the RMET-C. Both emotional valence and complexity of language contribute to RMET performance in individuals with ASD.

PURPOSE: ASD is associated with relative strengths in the visuospatial domain but varying abilities in the linguistic domain. Previous studies suggest parallels between spatial language and spatial cognition in older autistic individuals, but no research to date has examined this relationship in young autistic children. Therefore, the purpose of the present study was to investigate the connection between children’s spatial language production and nonverbal spatial cognition over time. We also examined two potential predictors of spatial language observed in previous literature, ASD symptom severity and parent spatial language input. METHODS: In past work investigating spatial language in NT children of the same age, parent-child interactions have been a primary context for study. Therefore, in the present study, we analyzed transcripts of dyadic naturalistic play interactions between autistic children and their parents over three visits from age 30 to 66 months and administered standardized cognitive and ASD diagnostic assessments at each visit. RESULTS: Spatial language production was related to nonverbal spatial cognition even when accounting for overall language production, though the strength of that relationship decreased over time. Parent spatial input (but not ASD severity) significantly predicted children’s spatial language production over and above the effect of overall language production. CONCLUSION: Spatial language is associated with spatial cognition in young autistic children and appears to reflect the interaction of overall linguistic skills and nonverbal spatial cognitive ability regardless of autism severity. Parent-mediated interventions may be a promising context for increasing spatial language in autistic preschoolers.

Requests for pathological demand avoidance (PDA) diagnoses have increased over recent years. However, PDA remains controversial. It was first coined by Elisabeth Newson who hypothesised that PDA differed from autism in specific areas. This case report presents two boys from different families whose parents have suggested PDA as the core problem. But both boys were diagnosed with autism and when reviewing their history, it became clear that they had been subjected to great stress for years as they had not been supported sufficiently at school. PDA may be the resulting behaviour of this.

OBJECTIVES: This study examined the changes in anxiety and depressive symptoms in the parents of Korean adults with autism spectrum disorder (ASD) after participating in the Korean version of the Program for the Education and Enrichment of Relational Skills for Young Adults (PEERS(®)-YA-K). METHODS: Forty-six parents were enrolled (mean age 54.7 years; 22 fathers and 24 mothers), of whom 27 participated in the PEERS(®)- YA-K as social coaches. Participants completed self-report scales, including the Test of Young Adult Social Skills Knowledge (TYASSK), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and Symptom Check-List-90-R (SCL-90-R). The scales were administered three times: before and after the 16-week program and 4 months after the program ended. Differences between participant variables at pretreatment, post-treatment, and follow-up were analyzed using paired-sample t-tests. RESULTS: Participants showed a significant improvement in their social skills knowledge (TYASSK) (p<0.01). There was a significant improvement in the BAI and BDI scores of parents with severe depressive and anxiety symptoms at the baseline (p<0.05). Paternal paranoia and maternal hostility results also significantly improved on the SCL-90-R. CONCLUSION: This study suggests that PEERS(®)-YA-K can reduce parental anxiety and depressive symptoms. To the best of our knowledge, this is the first to compare the degree of depression and anxiety after PEERS(®)-YA-K in parents of adults with ASD.

Some theories have proposed that autistic individuals have difficulty learning predictive relationships. We tested this hypothesis using a serial reaction time task in which participants learned to predict the locations of a repeating sequence of target locations. We conducted a large-sample online study with 61 autistic and 71 neurotypical adults. The autistic group had slower overall reaction times, but demonstrated sequence-specific learning equivalent to the neurotypical group, consistent with other findings of typical procedural memory in autism. The neurotypical group, however, made significantly more prediction-related errors early in the experiment when the stimuli changed from repeated sequences to random locations, suggesting certain limited behavioural differences in the learning or utilization of predictive relationships for autistic adults.
