A longitudinal examination of perinatal testosterone, estradiol and vitamin D as predictors of handedness outcomes in childhood and adolescenceThe developmental origins of handedness remain elusive, though very early emergence suggests individual differences manifesting in utero could play an important role. Prenatal testosterone and Vitamin D exposure are considered, yet findings and interpretations remain equivocal.

A genome-wide association study of total child psychiatric problems scoresSubstantial genetic correlations have been reported across psychiatric disorders and numerous cross-disorder genetic variants have been detected. To identify the genetic variants underlying general psychopathology in childhood, we performed a genome-wide association study using a total psychiatric problem score.

Quality of life beyond diagnosis in intellectual disability – Latent profilingTo compare quality of life (QOL) across diagnoses associated with intellectual disability, construct QOL profiles and evaluate membership by diagnostic group, function and comorbidities.

Harmonized Phenotypes for Anxiety, Depression, and Attention-Deficit Hyperactivity Disorder (ADHD)In multi-cohort consortia, the problem often arises that a phenotype is measured using different questionnaires. This study aimed to harmonize scores based on the Child Behaviour Check List (CBCL) and the Strength and Difficulties Questionnaire (SDQ) for anxiety/depression and ADHD.

Changes to the Gut Microbiome in Young Children Showing Early Behavioral Signs of AutismThe human gut microbiome has increasingly been associated with autism spectrum disorder (ASD), which is a neurological developmental disorder, characterized by impairments to social interaction.

Genome-wide analyses of individual differences in quantitatively assessed reading- and language-related skills in up to 34,000 peopleThe use of spoken and written language is a fundamental human capacity. Individual differences in reading- and language-related skills are influenced by genetic variation, with twin-based heritability estimates of 30 to 80% depending on the trait. The genetic architecture is complex, heterogeneous, and multifactorial, but investigations of contributions of single-nucleotide polymorphisms (SNPs) were thus far underpowered.

Factors Influencing Postoperative Experiences in Adult Cochlear Implant Recipients: A Multistakeholder PerspectiveTo explore factors influencing postoperative experiences of adult cochlear implant (CI) recipients, determine the impact of each factor, and conceptualize recipients' postoperative journey.

Assessing functioning for individuals with neurodevelopmental conditions: Current clinical practice in AustraliaIn the disability sector globally, and specifically in Australia, assessments of functioning have become key to diagnostic processes, and accessing therapy and funding. Over half of all individuals accessing support through Australia's National Disability Insurance Scheme have a neurodevelopmental condition diagnosis.
Research
The prevalence of and potential risk factors for Developmental Language Disorder at 10 years in the Raine StudyThis study sought to determine the prevalence of Developmental Language Disorder (DLD) in Australian school-aged children and associated potential risk factors for DLD at 10 years.
Research
Devising a Missing Data Rule for a Quality of Life Questionnaire - A Simulation StudyThe aim of this study was to devise an evidence-based missing data rule for the Quality of Life Inventory-Disability (QI-Disability) questionnaire specifying how many missing items are permissible for domain and total scores to be calculated using simple imputation.
Research
Dental procedures in children with or without intellectual disability and autism spectrum disorder in a hospital settingThis population-based cohort study investigated dental procedures in the hospital setting in Western Australian children with or without intellectual disability (ID) and/or autism spectrum disorder (ASD) aged up to 18 years.

Patterns of sensory modulation by age and sex in young people on the autism spectrumSensory modulation symptoms form a diagnostic criterion for autism spectrum disorder and are associated with significant daily functional limitations. Utilizing caregiver report on Short Sensory Profile-2 (SSP-2) for 919 autistic children (3–14.11 years), we examined the expression of sensory modulation symptoms by age and sex and investigated the existence of specific sensory modulation subtypes.
