Both the amount "and" responsiveness of adult language input contribute to the language development of autistic and non-autistic children. From parent-child interaction footage, we measured the amount of adult language input, overall parent responsiveness, and six discrete parent responsive behaviours ("imitations, expansions, open-ended questions, yes/no questions, comments" and "acknowledgements") to explore which types of responsiveness predicted autistic preschoolers' language five months later, after controlling for adult language input. We found "expansions" and particularly "imitations" to be more important for later language than overall responsiveness. This study emphasises the need to capture what exactly about parent language input influences child language acquisition, and adds to the evidence that imitating and expanding early language might be particularly beneficial for autistic preschoolers.

Many autistic children have co-occurring behavioural problems influencing core autism symptomology potentially relevant for intervention planning. Parental Expressed Emotion -- reflecting critical, hostile and overprotective comments -- contributes to understanding and predicting behaviour in autistic school-aged children, adolescents and adults and is typically measured using the Five-Minute Speech Sample. However, limitations exist for its use with parents of younger autistic children and so the Autism-Specific Five-Minute Speech Sample was adapted with the goal of better measuring parent Expressed Emotion in the context of childhood autism. The Autism-Specific Five-Minute Speech Sample has not yet been used to explore Expressed Emotion in parents of autistic "preschoolers," nor has the relative predictive utility of the Autism-Specific Five-Minute Speech Sample and Five-Minute Speech Sample been evaluated in the same sample. We compared the two measures from speech samples provided by 51 Australian parents with newly diagnosed autistic preschoolers, including investigating their predictive value for concurrent and subsequent child internalising and externalising behaviour problems. While Autism-Specific Five-Minute Speech Sample Expressed Emotion and Five-Minute Speech Sample Expressed Emotion were associated in this sample, only Autism-Specific Five-Minute Speech Sample codes contributed significant predictive value for concurrent and subsequent child problem behaviour. These preliminary data strengthen the position that the Autism-Specific Five-Minute Speech Sample may better capture Expressed Emotion, than the Five-Minute Speech Sample, among parents of autistic preschool-aged children.

Parents from individualist cultures (those focused on autonomy of individuals; that is, Australian) may view their autistic children differently compared to parents from collectivist cultures (where community needs are valued over an individual's, that is, South-East Asian cultures). As most research on autism and parenting has been undertaken in Western individualist cultures, knowledge of parenting beliefs and mental health within collectivist cultures is lacking. We compared the mental health, quality of life, well-being and parenting sense of competency between families raising an autistic child from two groups: 97 Australian parents and 58 parents from South-East Asian backgrounds. Children from both groups were receiving the same community-based early intervention. No group differences were found on the measures of mental health but, when compared to Australian parents, parents from South-East Asian backgrounds reported higher well-being and less impact on their quality of life resulting from their child's autism-specific difficulties. Furthermore, a positive association between well-being and quality of life was only observed for South-East Asian parents. Hence, the views of, and responses to, disability for South-East Asian parents may act as a protective factor promoting well-being. This novel research indicates that culture plays a role in parenting autistic children and highlights the need to accurately capture cultural background information in research.

Extensive research has shown elevated mental health difficulties among parents of children with autism compared to other parents. Although several studies have explored factors related to mental health among parents of children with autism, the factors that influence and promote well-being remain poorly characterised. Parents of young, newly diagnosed autistic children may also be particularly vulnerable to stressors that impact mental health and well-being. We examined child-, parent-, and family/socioeconomic factors associated with concurrent mental health and well-being among 136 parents of young children with autism, aged 13-48 months. Parental mental health was predicted by both trait negative emotionality and reported child autism symptoms, while well-being was predicted by parent factors alone, including trait extraversion and mindfulness. Broader child characteristics and family/socioeconomic contextual factors made no significant contribution in regression models. While the mental health and well-being of parents with young autistic children are associated with one another, unique predictors seem to exist. That well-being was uniquely predicted by a modifiable parent characteristic -- mindfulness -- suggests the potential for early supports to bring direct benefits for parents, in the context of raising a young child with autism.

Autism spectrum disorders (ASD) are neurodevelopmental disorders with an estimated heritability of >60%. Family‐based genetic studies of ASD have generally focused on multiple small kindreds, searching for de novo variants of major effect. We hypothesized that molecular genetic analysis of large multiplex families would enable the identification of variants of milder effects. We studied a large multigenerational family of European ancestry with multiple family members affected with ASD or the broader autism phenotype (BAP). We identified a rare heterozygous variant in the gene encoding 1,4‐ɑ‐glucan branching enzyme 1 (GBE1) that was present in seven of seven individuals with ASD, nine of ten individuals with the BAP, and none of four tested unaffected individuals. We genotyped a community‐acquired cohort of 389 individuals with ASD and identified three additional probands. Cascade analysis demonstrated that the variant was present in 11 of 13 individuals with familial ASD/BAP and neither of the two tested unaffected individuals in these three families, also of European ancestry. The variant was not enriched in the combined UK10K ASD cohorts of European ancestry but heterozygous GBE1 deletion was overrepresented in large ASD cohorts, collectively suggesting an association between GBE1 and ASD.

Little is known about executive functions (EFs) associated with advanced theory of mind (ToM) abilities. We aimed to determine if advanced ToM abilities were reduced in individuals with subclinical traits of autism spectrum disorder (ASD), known as the "Broader Autism Phenotype" (BAP), and identify the EFs that predicted unimpaired performance on an advanced ToM task, the faux pas test. We assessed 29 participants (13 males) with the BAP who were relatives of children with ASD. Thirteen participants showed reduced ability to understand a faux pas. A discriminant function analysis correctly classified 79% of cases as impaired or unimpaired, with high sensitivity (80%) and specificity (77%), which was best predicted by language‐mediated EFs, including verbal generativity, working memory, cognitive inhibition, and flexibility.

Lay Summary: Little is known about the complex cognitive processes that enable accurate interpretation of another person's thoughts and emotions, known as "theory of mind." In relatives of individuals with autism, who had mild traits of autism themselves, approximately half had difficulty interpreting situations involving a social faux pas. Cognitive inhibition and flexibility, working memory, and verbal generativity were related to, and appeared to be protective for, unimpaired understanding of a faux pas. [ABSTRACT FROM AUTHOR]

Purpose: Autistic children are reported to display higher levels of externalizing and internalizing behaviors than neurotypical children, and their parents report more stress than parents of neurotypical children. It is unclear whether child behavior difficulties contribute to increased parenting stress, whether parenting stress contributes to child behavior difficulties, or whether the relationship may be bidirectional., Methods: We investigated prospective bidirectional associations between parenting stress and child externalizing and internalizing behaviors when autistic children were aged on average 3.5, 4.5, and 5.5 years. Data collected at these three timepoints were examined across two panels: Time 1 to Time 2 (n = 38 parent-child dyads) and Time 2 to Time 3 (n = 27 dyads)., Results: Across Time 1 to Time 2, early parenting stress was significantly associated with later child externalizing behavior, and cross-lagged panel analysis supported a uni- rather than a bidirectional association between these factors. There was some evidence of a bidirectional association between parenting stress and child internalizing behavior, though this was non-significant when the strong stability of child internalizing behavior was statistically controlled. In contrast, across Time 2 to Time 3, there were no significant prospective associations found between variables, highlighting the importance of considering the impact of parenting stress early in the course of childhood autism., Conclusion: Our results add to research indicating that support targeting parent characteristics, especially parenting stress, could ameliorate subsequent outcomes for both parents and children., (© 2023.
