Autism and intellectual disability are differentially related to sociodemographic background at birthWe used population data on Western Australian singletons born from 1984 to 1999 (n = 398,353) to examine the sociodemographic characteristics of children...

Investigating associations between birth order and autism diagnostic phenotypesBirth order effects have been linked to variability in intelligence, educational attainment and sexual orientation. First- and later-born children have been linked to an increased likelihood of an Autism Spectrum Disorder (ASD) diagnosis, with a smaller body of evidence implicating decreases in cognitive functioning with increased birth order.

Content Validation of Clinician-Reported Items for a Severity Measure for CDKL5 Deficiency DisorderCDKL5 deficiency disorder (CDD) results in early-onset seizures and severe developmental impairments. A CDD clinical severity assessment (CCSA) was previously developed with clinician and parent-report items to capture information on a range of domains.

The longitudinal relationship between BOLD signal variability changes and white matter maturation during early childhoodIntra-individual transient temporal fluctuations in brain signal, as measured by fMRI blood oxygenation level dependent (BOLD) variability, is increasingly considered an important signal rather than measurement noise.

The Investigation of Health-Related Topics on TikTok: A Descriptive Study ProtocolThe social media application TikTok allows users to view and upload short-form videos. Recent evidence suggests it has significant potential for both industry and health promoters to influence public health behaviours. This protocol describes a standardised, replicable process for investigations that can be tailored to various areas of research interest, allowing comparison of content and features across public health topics.

IDEA (Intellectual Disability Exploring Answers) DatabaseIDEA is one of the few population-based resources in the world dedicated to intellectual disability. The IDEA database contains information on all children born in Western Australia since 1983 who have been identified with having an intellectual disability. Individuals with autism spectrum disorder, both with and without intellectual disability, are also included in the database. Deidentified information is accessed from the Department of Communities WA, the WA Department of Education, and the National Disability Insurance Agency (NDIA) to create the database. IDEA can be linked to other datasets to facilitate research into the determinants, outcomes and service needs of children and adults with intellectual disability. Researchers can apply for such linked data, available in a de-identified format under approval from an ethics committee.
