A prospective study of associations between early fearfulness and perceptual sensitivity and later restricted and repetitive behaviours in infants with typical and elevated likelihood of autism / Nisha NARVEKAR in Autism, 26-8 (November 2022)

Hoffmann-La Roche Ltd. and Servier, and has received royalties from Sage Publications and Guilford Publications. G.P. is a licensed ADOS-2 trainer and receives income from delivering ADOS-2 training. Index. décimale : PER Périodiques Résumé : Restricted interests and repetitive behaviours are central to the diagnosis of autism and can have profound effects on daily activities and quality of life. These challenges are also linked to other co-occurring conditions such as anxiety and sensory sensitivities. Here, we looked at whether early emerging signs of anxiety and sensory problems appear before symptoms of autism by studying infants with a family history of autism, as these infants are more likely to develop autism themselves. Studying infant siblings provides an opportunity for researchers to focus on early developmental markers of autism as these infants can be followed from birth. This study found that early infant signs of anxiety (e.g. fear/shyness) predicted later perceptual sensitivity, and those infants who scored higher on fear/shyness and sensitivity were more likely to experience more persistent repetitive behaviours, but also social and communication difficulties in toddlerhood. Early signs of anxiety and perceptual sensitivity may thus relate to both later social difficulties and repetitive behaviours. These findings support the importance of further research exploring the causal links between these domains in relation to autism, resulting in increased understanding of children who go onto develop autism in the future and guiding early interventions and supports.

Intolerance of uncertainty (IU) and anxiety mediate the relationship between sensory processing and RRB in autistic children. We replicated this model in autistic adults, extending it to include alexithymia. Serial mediation, using data from 426 autistic adults, identified significant direct effects from sensory processing to RMB and ISB, and indirect effects through alexithymia-IU-anxiety for RMB, and IU alone, and alexithymia-IU for ISB. Different mechanisms may underpin RMB and ISB. Alexithymia alongside, IU and anxiety, should be considered when understanding the relationship between sensory processing and RRB, and when offering interventions to support autistic people.

Ten young people also completed a novel semi-structured interview exploring an individualised example of an RRB. Findings demonstrated that young people with ASD can self-report and show insight in to their RRB, and replicated previous findings based on parent report showing a significant positive relationship between RRB and anxiety. This is the first evidence of young person self-report using both quantitative and qualitative data and indicates a range of reasons why young people may engage in RRB.

We sought to inform this issue through a systematic review and meta-analysis of potential sex differences specifically in young autistic children across a range of domains including core ASD features, social functioning, cognition, and co-occurring internalising and/or externalising conditions. The systematic review identified 35 studies examining sex differences in young autistic children. Conflicting results were evident across studies, with some reporting small sex differences and others reporting no sex differences. Meta-analysis revealed no overarching significant sex differences in the domains investigated. However, the meta-analytic effect for the RRB domain approached significance, with females demonstrating fewer RRBs than males. Many of the primary studies included here utilised data from standardised diagnostic instruments to measure autism features, so while this study suggests non-significant sex differences in early childhood ASD, it remains possible that current tools are insufficiently sensitive to detect differences in ASD presentation by sex at this age. It is also possible that the diagnostic criteria may reflect a predominately 'male phenotype' and this may obscure the detection of genuine sex differences in young autistic children.
