Objective: ADHD is a prevalent neurodevelopmental disorder characterized by symptoms of inattention and hyperactivity-impulsivity. Impairments in executive functioning (EF) are central to models of ADHD, while alpha-band spectral power event-related decreases (ERD) have emerged as a putative electroencephalography (EEG) biomarker of EF in ADHD.…

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…

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)…

Objective: To examine the Strengths and Weaknesses of ADHD--Symptoms and Normal Behavior scale (SWAN) clinical utility as a diagnostic measure of ADHD in an ADHD clinic sample. Method: In a sample of 357 children (6-11 years old) referred for evaluation at an academic medical center, we explored the SWAN's diagnostic and convergent validity with…

Objective: Children born preterm are at an elevated risk of developmental challenges, often exhibiting a distinct "preterm behavioral phenotype" characterized by particular attention difficulties. This review focuses on examining the phenotypical attention profile in preterm children aged 5 to 11 years, considering both clinical and…

This systematic review and meta-analysis explores the effectiveness of teacher interventions supporting children with externalizing behaviors based on teacher and child outcomes. A systematic search was conducted using 5 electronic databases. From 5714 papers, 31 papers that included interventions delivered directly to teachers and aimed to…

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 =…

Parenting interventions have been shown to be successful in supporting parents to address children's challenging behaviour. This systematic literature review explores the effectiveness of Non-Violent Resistance (NVR), a specific parenting intervention which aims to help parents cope with children's violent and controlling behaviour. It is a…

Children with neurodevelopmental disorders often have social-emotional and behavioural difficulties. The present study explored these difficulties in children (n = 50, aged 6-10 years) with autism spectrum disorder, attention-deficit/hyperactivity disorder and developmental language disorder. Parents, teachers and therapists evaluated children's…

Background: Fetal life and infancy might be critical periods for brain development leading to increased risks of neurocognitive disorders and psychopathology later in life. We examined the associations of fetal and infant weight growth patterns and birth characteristics with behavior and cognitive outcomes at the age of 13 years. Methods:…

Autistic youth engage in higher levels of screen time and are more likely to experience mental health problems than their typically developing peers; however, few studies have investigated a potential relationship between daily screen time hours and mental health in autistic youth. This study examined the relations among daily screen time hours…

The purpose of the present study is to compare risk and predictors of poor safety awareness and accidental injuries in ASD, ADHD, and neurotypical samples. Neurodivergent groups (ADHD-I n = 309; ADHD-C n = 747; ASD-only n = 328; ASD + ADHD n = 1,108) were 2-17 years old. The neurotypical group (n = 186) was 6-12 years of age. Maternal ratings on…

Objective: This study aimed to investigate the relationship between Cognitive Disengagement Syndrome (CDS) symptoms in children/adolescents and their parents within the Turkish population, examining the association with co-occurring ADHD symptoms, peer/social relationships, and total difficulties. Method: The study included 229 parents aged 18 to…

Children with complex behavioral profiles (e.g., ASD + ADHD) may experience delays in obtaining a final diagnosis. Low-resource or underrepresented groups may be at even greater risk for delayed diagnosis. We assessed the effect of sociodemographic factors, symptom complexity and co-occurring conditions, and identifier of first symptoms on…

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,…
