The interactions between sleep problems, autism symptoms and emotional and behavioural difficulties were explored using network analysis in 240 autistic children (mean age: 8.8 years, range 5-13 years) with moderate to severe sleep problems. Findings revealed a highly connected and interpretable network, with three separate clusters identified of…

The association between emotional and behavioural problems and language skills is well documented. However, specific links between these developmental domains remain unclear. This review synthesises associations between components of language skills and emotional and behavioural problems in children aged 6-11 years. PRISMA guidelines were…

Up to 80% of children with autism spectrum disorder (ASD) experience sleep problems, which have been associated with more severe presentations of ASD symptoms. We examined the bidirectional link between sleep problems and specific ASD symptoms at two time points within 5 years in a well-characterized sample (659 children with ASD). Using…

Introduction: Children with fetal alcohol spectrum disorder (FASD), a neurodevelopmental disorder associated with cognitive, emotional, and learning impairments have an increased likelihood of experiencing behavioral and socio-emotional difficulties and historical trauma. Methods: Using the interRAI Child and Youth Mental Health instrument, this…

Objective: This study examined the impact of family size and type on maternal rejection and its relationship with emotional-behavioral difficulties in children with ADHD compared to those typically developing. Method: The participants were mothers of 7- to 12-year-old children with ADHD (n = 102) and mothers of typically developing children (n =…

This study investigated the relationship between mathematics difficulties and psychopathology in a large community sample (N = 881) of youth (8-18 years of age) in the United States. The primary aims of the study were to (a) test the associations between mathematics difficulties and specific components of internalizing, externalizing, attention,…

Several studies have reported conflicting results when assessing associations between stress and repetitive behaviors in individuals with autism spectrum disorder (ASD). Some factors that may have caused these discrepant results include the monitoring of a single broad category for repetitive behaviors, the heterogeneity of the participants, and…

Anxiety and externalizing concerns create notable challenges for families. One factor that has been widely studied in relation to anxiety concerns, which may also be influenced by externalizing symptoms, is parental accommodation. Most research on parental accommodation has tended to focus on behaviors, while not accounting for accommodation…

Background: Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder, the etiology of which has not been clearly determined yet. There is increasing evidence that synaptic and dendritic changes are involved in the etiology of ASD. The aim of this study is to determine whether serum Thrombospondin-1 and Thrombospondin-2 differ between ASD…

Background: In children, internalizing and externalizing problems impact on learning. However, there is limited research on the specific impact of such problems on spatial working memory (SWM), strongly related to cognitive ability and children's learning. Aims: We explored distinct trajectories of internalizing problems and externalizing problems…

Childhood adversity takes a toll on lifelong health. However, investigations of unpredictability as a form of adversity are lacking. Environmental unpredictability across multiple developmental periods and ecological levels was examined using a multiethnic, longitudinal birth cohort (1998-2000) oversampled for unmarried parents. Data were from the…

Background: ADHD is the most common neurodevelopmental disorder. While much is known about the functional and academic impacts of ADHD, impacts on long-term health-related quality of life (HRQoL) are less well-documented. Aims: To explore, in children aged 4 to 17 years, associations between clinical ADHD symptoms and (1) children's HRQoL; (2)…

To explore associations between autism traits and family functioning over time, we studied longitudinal data of a mixed group of 168 clinically referred autistic and non-autistic children. Cross-lagged models showed a significant association between fewer autism traits at the diagnostic assessment and better family functioning 1 year later for the…

During childhood, the ability to limit problem behaviors (i.e., externalizing) and the capacity for cognitive regulation (i.e., executive function) are often understood to develop in tandem, and together constitute two major components of self-regulation research. The current study examines bi-directional relations between behavioral problems and…

Background: Children with developmental language disorder (DLD) are at higher risk of poorer mental health compared with children without DLD. There are, however, considerable individual differences that need to be interpreted, including the identification of protective factors. Aims: Pathways from the early language and communication environment…
