Relationship between early motor milestones and severity of restricted and repetitive behaviors in children and adolescents with autism spectrum disorderThis study provides the first evidence for the association between restricted and repetitive behaviors and age of attainment of early motor milestones.

Umbilical cord androgens and estrogens in relation to verbal and nonverbal abilities at age 10 in the general populationThese data suggest that late gestation sex steroids do not exert a major effect on nonverbal and verbal abilities in middle childhood.

Evidence of a reduction over time in the behavioral severity of autistic disorder diagnosesThis study provides the first clear evidence of a reduction over time in the behavioral severity of individuals diagnosed with Autistic Disorder during a period of stability in diagnostic criteria

Reduced goal-directed action control in autism spectrum disorderInvestigate whether impairments in the ability to execute flexible goal-directed actions may be an underlying feature in ASD contributing to these symptoms

Commentary: Are we expecting too much from the extreme male brain theory of autism? A reflection on Kung et al. (2016)This commentary highlights inconsistent findings that undermine the extreme male brain theory autism but data may not present an adequate test of the hypothesis

Short report: Relationship between restricted and repetitive behaviours in children with autism spectrum disorder and their parentsRestricted and repetitive behaviours constitute a core symptom domain of autism spectrum disorder

Characterizing the Nature of Alexithymia in Autistic Adults: Validation of the Perth Alexithymia QuestionnaireAlexithymia—a trait characterized by difficulties in emotion processing—is of high interest in the autism field. However, the lack of validated alexithymia measures for autistic individuals limits progress. This study aimed to address this gap by examining the psychometric properties of the Perth Alexithymia Questionnaire (PAQ) across autistic and non-autistic samples. Using the PAQ, we investigated how alexithymia manifests in autistic individuals and its links with poor mental health outcomes (anxiety).

Co-occurring Neurodevelopmental Conditions in Children: Advocating for Transdiagnostic Approach to AssessmentsApproximately 8% of all children experience developmental and mental health conditions. Similarities in characteristics across neurodevelopmental conditions-such as difficulties in communication and language, social interaction, motor coordination, attention, activity regulation, behavior, mood, and sleep-make it challenging to attribute these characteristics exclusively to specific diagnoses and assessments. The purpose of this study was to identify symptomatic domains across neurodevelopmental conditions in children and to explore dimension reduction for transdiagnostic assessment.

Caregiver broader autism phenotype does not moderate the effect of early caregiver-mediated support on infant language outcomesCaregiver-mediated supports in general have shown mixed evidence for enhancing language outcomes in infants at higher likelihood of autism. While caregivers play a substantial role in caregiver-mediated supports, little is known about whether caregivers' own subclinical autistic features - known as broader autism phenotype - may moderate infant language outcomes.

Early markers of adult symptoms of depression and anxiety in the Raine StudyEarly intervention offers the potential to mitigate adult mental illness; however, trials spanning decades present significant challenges, necessitating predictive early markers useable in trial settings. We hypothesised that parent evaluation using the child behaviour checklist (CBCL) total problem score at age two years predicted adult depressive and anxious symptoms and explored other potential parent ratings.
