The Comprehensive Autistic Trait Inventory (CATI): development and validation of a new measure of autistic traits in the general population

Traits and characteristics qualitatively similar to those seen in diagnosed autism spectrum disorder can be found to varying degrees in the general population. To measure these traits and facilitate their use in autism research, several questionnaires have been developed that provide broad measures of autistic traits [e.g. Autism-Spectrum Quotient (AQ), Broad Autism Phenotype Questionnaire (BAPQ)]. However, since their development, our understanding of autism has grown considerably, and it is arguable that existing measures do not provide an ideal representation of the trait dimensions currently associated with autism. Our aim was to create a new measure of autistic traits that reflects our current understanding of autism, the Comprehensive Autism Trait Inventory (CATI).

The associations between autistic and communication traits in parents and developmental outcomes in children at familial risk of autism at 6 and 24 months of age

Several studies have explored relationships between parent broader autism phenotype and offspring communication, and have reported that autistic-like traits in parents are related to offspring communication difficulties and autism severity. However, past research has focused on studying such associations in childhood and we know very little about them in infancy. With accumulating evidence that interventions administered during infancy may be most effective in reducing ASD symptoms, it is imperative to examine whether relationships between parent autistic-like traits and child communication appear even earlier during this critical period of life.

Investigating the impact of autistic children's feeding difficulties on caregivers

The aim of this study was to investigate the influence of children's autism characteristics, sensory profiles and feeding difficulties on caregiver-reported impact at mealtimes.

Genome-Wide Analyses of Vocabulary Size in Infancy and Toddlerhood: Associations With Attention-Deficit/Hyperactivity Disorder, Literacy, and Cognition-Related Traits

The number of words children produce (expressive vocabulary) and understand (receptive vocabulary) changes rapidly during early development, partially due to genetic factors. Here, we performed a meta-genome-wide association study of vocabulary acquisition and investigated polygenic overlap with literacy, cognition, developmental phenotypes, and neurodevelopmental conditions, including attention-deficit/hyperactivity disorder. 

Reliability of the Commonly Used and Newly-Developed Autism Measures

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.

Hypothesis-driven genome-wide association studies provide novel insights into genetics of reading disabilities

Reading Disability is often characterized by difficulties in the phonology of the language. While the molecular mechanisms underlying it are largely undetermined, loci are being revealed by genome-wide association studies.

Caregiver sensitivity predicts infant language use, and infant language complexity predicts caregiver language complexity, in the context of possible emerging autism

While theory supports bidirectional effects between caregiver sensitivity and language use, and infant language acquisition-both caregiver-to-infant and also infant-to-caregiver effects-empirical research has chiefly explored the former unidirectional path. In the context of infants showing early signs of autism, we investigated prospective bidirectional associations with 6-min free-play interaction samples collected for 103 caregivers and their infants (mean age 12-months; and followed up 6-months later).

Improving the Journey Before, During and After Diagnosis of a Neurodevelopmental Condition: Suggestions from a Sample of Australian Consumers and Professionals

The current study used a transdiagnostic approach to explore experiences of consumers and professionals on how the process of assessing and diagnosing neurodevelopmental conditions can be improved.

Discovery of 42 genome-wide significant loci associated with dyslexia

Reading and writing are crucial life skills but roughly one in ten children are affected by dyslexia, which can persist into adulthood. Family studies of dyslexia suggest heritability up to 70%, yet few convincing genetic markers have been found.

Do parent-reported early indicators predict later developmental language disorder? A Raine Study investigation

Developmental language disorder (DLD) is one of the most common neurodevelopmental conditions. Due to variable rates of language growth in children under 5 years, the early identification of children with DLD is challenging. Early indicators are often outlined by speech pathology regulatory bodies and other developmental services as evidence to empower caregivers in the early identification of DLD.
