Sex-Specific Effects of Birth Weight on Longitudinal Behavioral Outcomes: A Mendelian Randomization Approach Using Polygenic Scores

It is unclear whether sex differences in behavior arising from birth weight (BW) are genuine because of the cross-sectional nature and potential confounding in previous studies. We aimed to test whether sex differences associated with BW phenotype were reproducible using a Mendelian randomization approach, i.e., association between polygenic score (PGS) for BW and behavior outcomes across childhood and adolescence. 

Low-intensity parent- and clinician-delivered support for young autistic children in Aotearoa New Zealand: a randomised controlled trial

Aotearoa New Zealand does not provide publicly-funded intensive autism support. While parent-mediated supports are promising, children and families may also benefit from direct clinician support. We tested the efficacy of a low-intensity programme involving parent- and clinician-delivered support for autistic children.

‘It depends entirely on the nature of those supports’: Community perceptions of the appropriateness of early support services for autistic children

We do not know much about what support services people think are okay for young autistic children. This study was a survey of 253 people. We asked autistic adults, parents, and professionals from Australia and New Zealand whether they thought it was okay to provide support services to autistic children. 

Australian Clinicians’ Considerations When Choosing an Assessment of Functioning Tool for Children with Neurodevelopmental Conditions

In the Australian disability context, the assessment of children with neurodevelopmental conditions’ functioning (across all domains) is of increasing importance, particularly since the introduction of the National Disability Insurance Scheme. Currently, there is wide variability across assessment of functioning practices, including the choice and use of published tools for assessment.

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.

Factors Influencing Postoperative Experiences in Adult Cochlear Implant Recipients: A Multistakeholder Perspective

To explore factors influencing postoperative experiences of adult cochlear implant (CI) recipients, determine the impact of each factor, and conceptualize recipients' postoperative journey.

The effect of oxytocin nasal spray on social interaction in young children with autism: a randomized clinical trial

Early supports to enhance social development in children with autism are widely promoted. While oxytocin has a crucial role in mammalian social development, its potential role as a medication to enhance social development in humans remains unclear.

“It Was Such a Different Experience”: a Qualitative Study of Parental Perinatal Experiences When Having a Subsequent Child After Having a Child Diagnosed with Autism

Children who have an older sibling diagnosed with autism have an increased likelihood of being diagnosed with autism or developing broader developmental difficulties. This study explored perinatal experiences of parents of a child diagnosed with autism, spanning pre-conception until the subsequent child’s early developmental period.

Devising a Missing Data Rule for a Quality of Life Questionnaire - A Simulation Study

The 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.

A systematic review of the biological, social, and environmental determinants of intellectual disability in children and adolescents

This systematic review aimed to identify the most important social, environmental, biological, and/or genetic risk factors for intellectual disability.
