Psychometric evaluation of the Comprehensive Autistic Trait Inventory in autistic and non-autistic adults

Measures of autistic traits are only useful – for pre-diagnostic screening, exploring individual differences, and gaining personal insight – if they efficiently and accurately assess autism as currently conceptualised while maintaining psychometric validity across different demographic groups. We recruited 1322 autistic and 1279 non-autistic adults who varied in autism status (non-autistic, diagnosed autistic, self-identifying autistic) and gender (cisgender men, cisgender women, gender diverse) to assess the psychometric properties of the Comprehensive Autistic Trait Inventory, a recently developed measure of autistic traits that examines six trait domains using 42 self-report statements.

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.

Intellectual disability and autism prevalence in Western Australia: impact of the NDIS

Estimates of the prevalence of intellectual disability or autism spectrum disorder may vary depending on the methodology, geographical location, and sources of ascertainment. The National Disability Insurance Scheme in Australia was introduced progressively from 2016 to provide individualized funding for eligible people with a significant and permanent disability.

Community Priorities for Outcomes Targeted During Professional Supports for Autistic Children and their Families

Professional supports play an important role in aiding autistic children's learning, participation, and overall wellbeing. Yet, limited research exists on stakeholders' perspectives and preferences regarding targeted outcomes for children undergoing support facilitated by professionals.

CRISPR-Cas9-generated PTCHD1 2489T>G stem cells recapitulate patient phenotype when undergoing neural induction

An estimated 3.5%-5.9% of the global population live with rare diseases, and approximately 80% of these diseases have a genetic cause. Rare genetic diseases are difficult to diagnose, with some affected individuals experiencing diagnostic delays of 5-30 years. Next-generation sequencing has improved clinical diagnostic rates to 33%-48%. In a majority of cases, novel variants potentially causing the disease are discovered. 

Investigation of associations between self-reported sensory processing, eating disorder symptoms, neurodivergence, and gender congruence from a lived experience lens

Eating disorders (EDs) are increasingly recognised among neurodivergent and transgender and gender diverse (TGD) individuals, yet most assessment and treatment models remain grounded in cisnormative and neuronormative assumptions and frameworks. Sensory processing, spanning interoception and exteroception, has been proposed as a potential factor that may help explain observed associations between neurodivergent traits, gender incongruence, and EDs. 

Characterizing Transdiagnostic Processes Underlying the Drive to Socially Engage: A Multimeasurement Factor Analytic Investigation

Altered drive to socially engage is a transdiagnostic feature across multiple psychopathologies. Yet, lack of clarity regarding specific processes that constitute social drive, along with insufficient measurement methods, has hindered understanding in this area. This study ascertained the feasibility of approximating difficulties within specific fine-grained social drive processes as proposed by 2 theoretical frameworks: “orienting,” “wanting,” “pursuing,” “liking,” “learning,” and “reticence” within a reward processing framework and “orienting,” “seeking and maintaining,” and “liking” within a social motivation framework.

Parent-child interaction and developmental outcomes in children with typical and elevated likelihood of autism

Early parent-child interactions have a critical impact on the developmental outcomes of the child. It has been reported that infants with a family history of autism and their parents may engage in different patterns of behaviours during interaction compared to those without a family history of autism. This study investigated the association of parent-child interactions with child developmental outcomes of those with typical and elevated likelihood of autism.
