Data from children with ASD who are learning Indo-European languages indicate that (a) they vary hugely in their expressive language skills and (b) their pragmatic/socially-based language is more impaired than their structural language. We investigate whether similar patterns of language development exist for Mandarin-exposed children with ASD. Parent report data of the Putonghua Communicative Development Inventory-Toddler Form were collected from 160 17-83-month-old children with ASD. These children with ASD demonstrated similar levels of variability as Western children with ASD...

Aberrant interoceptive accuracy could contribute to the co-occurrence of anxiety and premonitory urge in chronic tic disorders (CTD). If it can be manipulated through intervention, it would offer a transdiagnostic treatment target for tics and anxiety. Interoceptive accuracy was first assessed consistent with previous protocols and then re-assessed following an instruction attempting to experimentally enhance awareness. The CTD group demonstrated lower interoceptive accuracy than controls but, importantly, this group difference was no longer significant following instruction...

Recent studies suggest that circumscribed interests (CI) in females with Autism Spectrum Disorder (ASD) may align more closely with interests reported in typical female development than those typically reported for ASD males. We used eye-tracking to quantify attention to arrays containing combinations of male, female and neutral images in elementary-aged males and females with and without ASD. A number of condition × sex effects emerged, with both groups attending to images that corresponded with interests typically associated with their biological sex...

This review (Prospero Registration Number: CRD42017057915) aimed to systematically identify and summarize existing research on the relationship between additional emotional and behavioral problems (EBP) in children with autism, and parenting stress (PS) and mental health problems (MHP) in their parents. Sixty-seven studies met criteria for inclusion in the review, 61 of which were included in the meta-analysis. Pooled correlation coefficients were in the low to moderate range ([Formula: see text]). Some evidence for moderation by measurement characteristics was found...

Early communication impairment is among the most-reported first concerns in parents of young children with autism spectrum disorder (ASD). Using a parent-report questionnaire, we derived trajectory groups for early language and gesture acquisition in siblings at high risk for ASD and in children at low risk, during their first 2 years of life. Developmental skills at 6 months were associated with trajectory group membership representing growth in receptive language and gestures. Behavioral symptoms also predicted gesture development...

A randomised controlled trial evaluated the effectiveness of the Integrated Employment Success Tool (IEST™) in improving employers' self-efficacy in modifying the workplace for individuals on the autism spectrum. Employers (N = 84) were randomised to the IEST™ or support as usual groups. Measurements of self-efficacy, knowledge and attitudes towards disability in the workplace were obtained at baseline and post-test. Results revealed a significant improvement in self-efficacy within the IEST™ group between baseline and post-test (p = 0...

Specific developmental concerns can distinguish between an early versus later diagnosis of autism spectrum disorder (ASD). Caregiver survey responses of children ≥ 9 years-of-age (2012) with ASD were used to evaluate developmental concerns and associations with age of diagnosis [early (< 3 years: n = 106) vs. later (≥ 3 years: n = 432)] using logistic regression. Concerns arose at mean age 18 and 35-months for children diagnosed early versus later, respectively. Concerns about poor eye contact (aOR 1...

Recently, there has been increased attention to a putative relationship between Autism Spectrum Disorder (ASD) and gender dysphoria, the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5) diagnosis for those whose gender assigned at birth does not match their gender identity. Studies have shown an over-representation of ASD symptoms among transgender youth. These studies, however, have used scales that are non-specific for ASD. These ASD symptoms may represent social deficits that are secondary to social stress and deprivation, as transgender youth suffer high rates of peer and family rejection...

Recent evidence suggests the male predominance in Autism Spectrum Disorder (ASD) may be decreasing. Secondary analyses of Australian Medicare data (paediatrician/child psychiatrist items for diagnosing ASD before age 13) were used (N = 73,463 unique children from 1-July-2008 to 30-June-2016). Cumulative incidence of ASD in 4-year-olds in 2015/2016 was 1.10% [95% CI 1.06-1.14], males 1.66% [95% CI 1.60-1.72] and females 0.51% [95% CI 0.47-0.55]. New diagnoses significantly increased in older (5-12 years) males and females but not younger (0-4 years) children, from 2010/2011 to 2015/2016...

Increasing attention is being paid to how adults on the autism spectrum perceive and interpret the interoceptive sense. This 20-item Interoception Sensory Questionnaire represents a single factor scale that can be interpreted as representing confusion about interoceptive bodily states unless these states are extreme (Alexisomia), and has been designed to discriminate across populations (total sample 511 participants). Findings showed that 74% of adults with autism reported interoceptive confusion. Another finding of the study was that as autistic traits increased, interoceptive confusion increased, with adults with diagnosed autism scoring highest on the construct...

Relatively limited research has been devoted to understanding the postsecondary experience from the students' perspectives. In the current study, individual interviews were conducted with university students with autism spectrum disorder (n = 13) and students with Attention Deficit/Hyperactivity Disorder (n = 18) to investigate likely factors impeding meaningful postsecondary experiences. Through an iterative coding process, nine themes were identified, and direct narratives exemplifying each are included...

This study compared a behavioral feeding intervention with and without pre-meal sensory integration therapy (SIT) in two boys with autism spectrum disorder and severe food selectivity. For both participants, child bite and drink consumption and total intake increased to similar levels with corresponding decreases in inappropriate mealtime behavior (IMB) in both conditions. The SIT condition was then discontinued and both participants continued to exhibit high levels of bite and drink consumption with corresponding low levels of IMB during a non-SIT phase...

Reduced social motivation is hypothesised to underlie social behavioural symptoms of Autism Spectrum Disorder (ASD). The extent to which rewarding social stimuli are granted privileged access to awareness in ASD is currently unknown. We use continuous flash suppression to investigate whether individuals with and without ASD show privileged access to awareness for social over nonsocial rewarding scenes that are closely matched for stimulus features. Strong evidence for a privileged access to awareness for rewarding social over nonsocial scenes was observed in neurotypical adults...

The relationship between brain development and clinical heterogeneity in autism (ASD) is unknown. This study examines the Social Responsiveness Scale (SRS) in relation to the longitudinal development of cortical thickness. Participants (N = 91 ASD, N = 56 TDC; 3-39 years at first scan) were scanned up to three times over a 7-year period. Mixed-effects models examined cortical thickness in relation to SRS score. ASD participants with higher SRS scores showed regionally increased age-related cortical thinning...

This study examined how 34 senior students and first-year college students with autism spectrum disorder, their mothers (n = 34) and fathers (n = 26) navigate the higher education transition, and how this context impacts on dynamics in the parent-child relationships. Semi-structured interviews were analyzed based on grounded theory and dyadic analysis principles. Both parties were confronted with an abundance of challenges and experienced strong feelings of ambivalence, stress and anxiety. Differences in perspectives occurred regarding the construction of adulthood, the acquisition of autonomy, disclosure and subscribing to support services...

There is a gap in our knowledge of aging with autism. The present study examined the applicability of the popular gerontology concept of "aging well" to autistic adults. Using survey data, a model of "aging well" was operationalised and applied to 92 autistic adults and 60 controls. A very small proportion (3.3%) of autistic adults were found to be aging well. Significantly less autistic adults were "maintaining physical and cognitive functioning" and "actively engaging with life" in comparison to controls...

This study used a prospective community-based sample to describe patterns and predictors of language development from 4 to 7 years in verbal children (IQ ≥ 70) with autism spectrum disorder (ASD; n = 26-27). Children with typical language (TD; n = 858-861) and language impairment (LI; n = 119) were used for comparison. Children with ASD and LI had similar mean language scores that were lower on average than children with TD. Similar proportions across all groups had declining, increasing and stable patterns...

High rates of gender variance have been reported in autistic people, with higher variance in autistic females than males. The social component of gender identity may be affected, with autistic females experiencing lower identification with and feeling less positively about their gender groups than controls. We measured gender identification, gender self-esteem, and aspects of gender expression (masculinity and femininity) in autistic natal males and females, and controls (N = 486). We found that autistic people had lower gender identification and gender self-esteem than controls, and autistic natal females had lower gender identification than autistic natal males and natal female controls...

Our study examines the Diagnostic and Statistical Manual-Fifth Edition (DSM-5) and Diagnostic and Statistical Manual-Fourth Edition, Text Revision (DSM-IV-TR) when applied concurrently against the best estimate clinical diagnoses for 110 children (5.1-19.6 years old) referred for diagnostic assessments of Autism Spectrum Disorder (ASD) in a Singaporean outpatient speciality clinic. DSM-IV-TR performed slightly better, yielding sensitivity of 0.946 and specificity of 0.889, compared to DSM-5 (sensitivity = 0...
