Arriving at the empirically based conceptualization of restricted and repetitive behaviors: A systematic review and meta-analytic examination of factor analyses

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 first six months of life: A systematic review of early markers associated with later autism

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.

The relationship between pitch contours in infant-directed speech and early signs of autism in infancy

Mother-infant interactions during the first year of life are crucial to healthy infant development. The infant-directed speech (IDS), and specifically pitch contours, used by mothers during interactions are associated with infant language and social development.

Andrew Whitehouse: environmental links to autism

Dr Andrew Whitehouse says results from a US study are just the first step when it comes to looking for environmental factors related to autism.

New study shows fetal head size could link to autism

Research has found a link between children with larger head measurements in-utero and a subsequent diagnosis of Autism Spectrum Disorder (ASD) as toddlers.

Better diagnosis leads to higher autism rates

The rapid increase in the number of children diagnosed with autism spectrum disorders (ASD) in Western Australia reflects changes to diagnostic practices

Application of Population-Based Linked Data to the Study of Intellectual Disability and Autism

Data linkage is the bringing together of specific datasets from different sources using demographic information on individuals within a population.
