BACKGROUND: Autistic children experience more stressful life events (SLEs) than their neurotypical peers, which are related to poor mental health outcomes in both neurotypical and autistic individuals. However, there is a lack of longitudinal research assessing the perceived impact of stressful life events on autistic children's mental health. METHOD: Utilizing a novel statistical technique (Ratcliff et al., 2019), called 'area of resilience to stress events' or ARSE in R, we aimed to quantify aspects of resilience, growth, and non-resilience for 67 autistic children (6-13 years old) enrolled in a larger longitudinal study who experienced a SLE...

BACKGROUND: Rates of psychiatric hospitalization among adolescents in the United States are rising, with many adolescents presenting to these settings with diverse clinical presentations, including autistic traits. To our knowledge, there has been little research identifying clinical characteristics of adolescents with autistic traits admitted to psychiatric inpatient units, which may be leveraged to improve assessment and treatment practices. METHOD: In the current study, we examined clinical and demographic characteristics of 195 adolescents admitted to an adolescent psychiatric inpatient unit...

BACKGROUND: Autistic females are frequently underdiagnosed, misdiagnosed, and/or diagnosed later in life. Restricted and Repetitive Behaviors (RRBs) are increasingly critical for diagnosis and yet are commonly rated lower in females. Whether this reflects genuinely lower levels of these traits, or if female-typical RRBs have a different phenotypic presentation that may not register on current quantitative measurement tools is unclear. METHODS: Twenty-one autistic females and 21 autistic males matched on chronological age and FSIQ completed the AQ, ADOS-2, and ADI-R...

BACKGROUND: Children on the autism spectrum encountered interruptions to their education due to the COVID-19 pandemic (White et al., 2021). This study examined the extent to which autistic children's anxiety and depressive symptoms during the pandemic were associated with the school format they attended in October 2020 (remote, in-person/hybrid, homeschool), controlling for their pre-pandemic symptoms. Pre-pandemic peer victimization and autism symptom characteristics were tested as moderators...

Recent trends suggest that autism is more common in females than traditionally held. Additionally, some argue that females express autistic traits differently than males. Dimensional views of autism could shed light on these issues, especially with regards to understudied behavioral areas, such as sensory processing. We examined autistic traits, sensory processing, anxiety, and related behaviors in a large sample of neurotypical young adult males and females ( n = 1,122; 556 female; ages 19-26). Participants completed an online survey containing questionnaires related to the above...

BACKGROUND: Pragmatic language weaknesses, a core feature of autism spectrum disorder (ASD), are implicated in externalizing behavior disorders (Gremillion & Martel, 2014). Particularly in a clinical setting, these co-occurring externalizing disorders are very common in autism; rates of Attentional Deficit-Hyperactive Disorder (ADHD) and Oppositional Defiant Disorder (ODD) are as high as 83% (ADHD) and 73% (ODD; Joshi et al., 2010). It is possible that pragmatic language weaknesses impact the ability to effectively communicate one's needs, which may lead autistic children to utilize externalizing behaviors in order to achieve a desired outcome (Ketelaars et al...

BACKGROUND: Sleep disturbances, gastrointestinal problems, and atypical heart rate are commonly observed in patients with autism spectrum disorder (ASD) and may relate to underlying function of the autonomic nervous system (ANS). The overall objective of the current study was to quantitatively characterize features of ANS function using symptom scales and available electronic health record (EHR) data in a clinically and genetically characterized pediatric cohort. METHODS: We assessed features of ANS function via chart review of patient records adapted from items drawn from a clinical research questionnaire of autonomic symptoms...

BACKGROUND: Difficulties with praxis, the ability to perform learned skilled movements, have been robustly demonstrated in autism spectrum disorder (autism). However, praxis assessment is not routinely included in autism characterization batteries, in part because it is traditionally time consuming to administer and score. We test whether dyspraxia in autism can be captured with a brief measure. METHOD: Youth with autism ( n = 41) and matched typically developing controls ( n = 32), aged 8 to 16 years, completed a 5-minute praxis battery...

BACKGROUND: COVID-19 increased uncertainty for most and was especially disruptive to autistic people and their families, due in part to tendencies toward intolerance for uncertainty across this population. As such, COVID presented a natural experiment of uncertainty and its correlates in autism. Previous reports have shown associations between intolerance of uncertainty, sensory difficulty, and stress. AIMS: We investigated changes in sensory difficulties and stress associated with COVID-related increases in uncertainty...

BACKGROUND: Youth with Autism Spectrum Disorder (ASD) are at-risk for sleep and behavior problems, and their parents are at-risk for high stress. Child sleep duration, behavior problems, and parenting stress are interrelated; however, directionality of these associations is unclear and research including youth with ASD is lacking. Using a day-to-day, within-person design, this study explores the directionality of these relationships in families of children with ASD. METHOD: Twenty-six children (ages 3-5, 73...

BACKGROUND: Speech articulation difficulties have not traditionally been considered to be a feature of Autism Spectrum Disorder (ASD). In contrast, speech prosodic differences have been widely reported in ASD, and may even be expressed in subtle form among clinically unaffected first-degree relatives, representing the expression of underlying genetic liability. Some evidence has challenged this traditional dichotomy, suggesting that differences in speech articulatory mechanisms may be evident in ASD, and potentially related to perceived prosodic differences...

BACKGROUND: Up to 80% of children with autism experience behavioural sleep problems, predominantly relating to bedtime resistance, sleep anxiety, sleep dysregulation, and shorter duration, which are associated with increased autistic symptom expression and emotional and behavioural difficulties. Researchers predicted the COVID-19 pandemic would worsen sleep and behavioural difficulties for autistic children, due to their need for routine and certainty. This systematic review is the first to focus on delineating the role of sleep disturbance in exacerbating autistic symptoms and internalising and externalising behaviours during the pandemic...

BACKGROUND: Adolescents and young adults with autism spectrum disorder (ASD) are prone to experience co-occurring mental health conditions such as mood or anxiety disorders, as well as impairments in emotion regulation and executive functioning. However, little research has examined inter-relationships among these constructs, despite evidence of additional stressors and increased risk of internalizing disorders at this age, relative to non-autistic individuals. If either emotion regulation or executive functioning are shown to have patterns of association with mental health, this can inform mechanism-based intervention...

BACKGROUND: Difficulties with narrative have been reported in individuals diagnosed with autism spectrum disorder (ASD), but the role of executive function on narrative ability has not been examined in ASD. In this study, we aimed to (1) examine whether narrative abilities of ASD children differed from neurotypical (NT) children who did not differ in age, sex, and IQ; and (2) investigate relations between executive function and narrative ability in ASD children. METHOD: Narratives were elicited from 64 ASD children and 26 NT children using a wordless picture book and coded to derive several aspects of narrative ability such as propositions, evaluative devices, and self-repairs...

BACKGROUND: Individuals diagnosed with autism spectrum disorder (ASD) commonly experience difficulties maintaining social gaze with others during interactions. Although behavioral interventions targeted to promote social gaze in ASD are evident in the literature, to our knowledge, no review of the literature has been conducted to summarize and evaluate the evidence for these interventions. METHODS: We reviewed and summarized behavioral intervention studies designed to promote social gaze in individuals diagnosed with ASD and other developmental disabilities published in English between 1977 and January 2022 using PsychINFO and PubMed databases...

BACKGROUND: An emerging body of evidence suggests that autistic people are at greater risk for mortality than non-autistic people. Yet, relatively little is known about mortality rates among autistic people during older adulthood (i.e., age 65 or older). METHODS: We examined 5-year mortality among a national US sample of Medicare-enrolled autistic (n=3,308) and non-autistic (n=33,080) adults aged 65 or older. RESULTS: Autistic older adults had 2...

BACKGROUND: Maternal hormonal risk factors for autism spectrum disorder (ASD) in offspring could intersect genetic and environmental risk factors. OBJECTIVES: This analysis explored ASD risk in association with maternal testosterone, androstenedione, and dehydroepiandrosterone (DHEA) measured in first, second, and third trimesters of pregnancy. METHODS: MARBLES is a prospective pregnancy cohort study based at the MIND Institute in Northern California that enrolls mothers who have at least one child previously diagnosed with ASD and are expecting, or planning to have another child...

Background: Assessments for children with autism spectrum disorder (ASD) must adapt to the current COVID-19 pandemic through innovation in screening and assessment strategies using technology. To our knowledge there are no such studies reported from India. We aimed to study the predictive ability of video-based screening tool with definitive diagnosis in children with ASD. Method: Thirty-nine children were screened independently by two examiners with a video-based screening tool to start intervention followed by an in-person evaluation by clinical DSM-5 diagnosis three months later...

BACKGROUND: Difficulties with emotion regulation (ER) underlie emotional/behavioral challenges and co-occurring psychiatric symptoms in autism spectrum disorder (ASD), yet very little is known about the early development of emotion dysregulation. The present study aimed to identify differences in positive and negative emotional reactivity and regulation strategies in toddlers with and without ASD. METHOD: Nine tasks from the Laboratory Temperament Assessment Battery (Lab-TAB) were completed with 37 toddlers with and without ASD (22-28 months)...

BACKGROUND: Healthcare independence refers to someone's ability to assume responsibility for their own health and complete tasks like taking medication as prescribed or scheduling healthcare appointments. Prior studies have shown that autistic people tend to need more support with healthcare tasks than people with other chronic conditions. We sought to identify modifiable and non-modifiable factors linked with healthcare independence among autistic adults. METHOD: We conducted a cross-sectional survey to examine how executive functioning skills, restrictive and repetitive behaviors, gender, education, and age were linked with healthcare independence among this population...
