There is now good evidence that behavioural signs of autism spectrum conditions (autism) emerge over the first two years of life. Identifying clear developmental differences early in life may facilitate earlier identification and intervention that can promote longer-term quality of life. Here we present a systematic review of studies investigating behavioural markers of later autism diagnosis or symptomology taken at 0-6 months.
An empirically based understanding of the factor structure of the restricted and repetitive behaviors (RRB) domain is a prerequisite for interpreting studies attempting to understand the correlates and mechanisms underpinning RRB and for measurement development. Therefore, this study aimed to conduct a systematic review and meta-analysis of RRB factor analytic studies.
The aim of the present study was to compare scale and conditional reliability derived from item response theory analyses among the most commonly used, as well as several newly developed, observation, interview, and parent-report autism instruments.
Circumscribed interests encompass a range of different interests and related behaviors that can be characterized by either a high intensity but otherwise usual topic [referred to as restricted interests] or by a focus on topics that are not salient outside of autism [referred to as unusual interests].
A broad range of interests characterized by unusual content and/or intensity, labeled as circumscribed interests are a core diagnostic feature of autism. Recent evidence suggests that a distinction can be drawn between interests that, although characterized by unusually high intensity and/or inflexibility, are otherwise common in terms of their content (e.g., an interest in movies or animals), labeled as restricted interests and interests that are generally not salient outside of autism (e.g., an interest in traffic lights or categorization), labeled as unusual interests.
The identification of reproducible subtypes within autistic populations is a priority research area in the context of neurodevelopment, to pave the way for identification of biomarkers and targeted treatment recommendations. Few previous studies have considered medical comorbidity alongside behavioural, cognitive, and psychiatric data in subgrouping analyses.
Although up to 89% of autistic children experience feeding difficulties, little is known about the impact of these difficulties on mealtime participation. The aim of this study was to explore the impact of feeding difficulties on the mealtime participation of autistic children and their families based on caregiver experiences.
Autistic children have an increased likelihood of anxiety, but more research is needed on the characteristics that predict various types of anxiety in this population.
We do not know much about what support services people think are okay for young autistic children. This study was a survey of 253 people. We asked autistic adults, parents, and professionals from Australia and New Zealand whether they thought it was okay to provide support services to autistic children.
Aotearoa New Zealand does not provide publicly-funded intensive autism support. While parent-mediated supports are promising, children and families may also benefit from direct clinician support. We tested the efficacy of a low-intensity programme involving parent- and clinician-delivered support for autistic children.
