Compare developmental profiles and core ASD symptom manifestation between male and female toddlers with DSM-5 ASD. Retrospective record review of 500 toddlers (79% male) at time of ASD diagnosis. There were no differences in developmental functioning between males and females. When adjusting for multiple comparisons, sex differences were only…

The purpose of this project was to investigate potential correlates of family life impairment in families of young autistic children. This project incorporated measures of specific child and parent challenges in addition to a commonly used unidimensional measure of autism characteristics. In this way, we could assess whether such challenges…

Investigate the association between gastrointestinal (GI) issues and psychometric scores among children with developmental delays and typical development. We examined the association between GI issues and the Mullen Scale of Early Learning (MSEL), Vineland Adaptive Behavior Subscales (VABS), and Aberrant Behavior Checklist (ABC) scores from…

Gender-typical play is observed throughout childhood for non-autistic children. However, there has been limited research into the gender typicality of autistic children's play compared to that of non-autistic children. In a longitudinal population-based cohort, we compared gendered play behaviours in autistic and non-autistic children using…

Background: Sensory processing differences are reported both in children with ADHD and in children with autism. Given the substantial overlap between autism and ADHD, the current study examined which sensory features were uniquely predictive of autistic traits after controlling for ADHD symptoms, age, IQ, and sex in a sample of children and…

Inhibitory control (IC) ability in early childhood is associated with positive socioemotional, academic, and behavioural outcomes later in life. However, inhibitory control in young children with autism spectrum disorder (ASD) is not well understood. We conducted a large, cross-sectional study comparing IC ability of young children with ASD and…

Method: Sixty-one parents of children with intellectual disabilities or autism spectrum disorder (aged 13-30) reported children's PSB and emotional, behavioural, cognitive, and interpersonal factors. The frequency of PSB in…

Emotional and behavioural problems occur more commonly in children with Autism Spectrum Disorder (ASD) compared to other children.

We assessed via parent report the emotional and behavioural problems in 160 children aged 4-17 years with ASD attending…

Objectives: The COVID-19 pandemic has shown that people with disabilities are the most vulnerable, neglected and discriminated individuals at times of emergency. National and international studies are needed to understand the extent to which the general well-being, quality of life, and positive and negative behaviors of children with ASD are…

Mounting evidence finds that early life environmental factors increased the probability of autism spectrum disorder. We estimated prospective associations between early life environmental factors and autism spectrum disorder symptoms in children at the age of 2 years in a population-derived birth cohort, the Barwon Infant Study. Autism spectrum…
