Objective: This cross-sectional study investigated social opportunities in children at risk for ADHD in regular primary education classrooms. First, we aimed to compare social preference of children at risk for ADHD and of their unilateral friends, with their classmates. Second, we hypothesized that for the at risk-group higher levels of problem…

Background: ADHD is highly prevalent in adolescents. ADHD is characterized by heightened impulsive behavior and is often associated with increased risk-taking behavior in adolescence. Previous research has mostly focused on negative aspects of risk-taking behavior. However, recently two other types of risk-taking behavior have been identified:…

Cross-sectional research shows that adolescents' social media use (SMU) and attention deficit hyperactivity disorder (ADHD)-symptoms are related, but it is unclear whether this relation is explained by SMU intensity or by addiction-like SMU problems. Also, due to the lack of longitudinal studies, the direction of this relation remains unknown.…

We tested whether adoptive parenting played a role in the association between pre-adoption experiences and children's adaptive (responsiveness) and maladaptive (internalizing and externalizing behavioral problems, attention and sleep problems) behavioral adjustment over time. Ten-year-old girls, adopted at 13 months from institutional care (n =…

Objective: Previous studies at child and youth mental health services (CYMHS) suggest that children with ADHD have poorer outcomes compared to those with other diagnoses. This study investigates this in more detail. Methods: Children with ADHD were compared to those with ASD and those with emotional disorders, on routinely collected outcomes at…

There has been an increased focus on listening to students' voices in inclusive education in the last decade. To ensure the right of students to be heard and educational needs can be met in the Dutch education system, we set up a qualitative study to gain more insight into: 1) the problems that students experience at school, 2) how and from whom…

A retrospective chart study of patients on open-label aripiprazole treatment was conducted in the Netherlands to add to the knowledge of aripiprazole in children and young adults with mild and borderline intellectual disabilities (IDs). Fifty-three youths, mean age 14.7 ± 3.4 years and mean IQ 64.5 ±13.8, were included. Treatment responders were…

Background: Changes in reward processing are thought to be involved in the etiology of attention-deficit/hyperactivity disorder (ADHD), as well as other developmental disorders. In addition, different forms of therapy for ADHD rely on reinforcement principles. As such, improved understanding of reward processing in ADHD could eventually lead to…

Difficulties in peer acceptance during elementary school have been associated with emotional and behavioural problems. This study used a randomized controlled intervention design to test whether improvements in peer acceptance mediated reduced rates of emotional and behavioural problems in intervention compared to control-group children. A total…

Moffitt, Caspi, Harrington, and Milne (2002) found in a follow-up study that many of the supposedly adolescence-limited offenders had committed offenses past adolescence. This finding raises the question of whether adulthood starts later or whether there are two distinct delinquency types, adolescence limited and adolescence onset, each with its…

Research on school bullying often focuses on the directional path of bullying and/or victimization leading to psychosocial problems, while such one-dimensional views have been shown to be too simplistic. Furthermore, recent research has shown that patterns of bullying at school differ for boys and girls, which makes gender a particularly relevant…

The present study first examined the links between reactive temperament (negative affectivity), regulative temperament (effortful control [EC]) and internalizing problems in adolescents (12-18 years) with anxiety disorders (ANX; N = 39) and without anxiety disorders (nANX; N = 35). Links differed between ANX and nANX participants. Negative…

Few classroom behavioral interventions have been thoroughly studied using culturally and linguistically diverse populations, international student populations, or those from diverse socio-economic backgrounds. Yet, having such tools for school psychologists and teachers is critical for behavior management in the classroom. One important exception…

Background: Maternal depression and anxiety during pregnancy have been associated with offspring-attention deficit problems. Aim: We explored possible intrauterine effects by comparing maternal and paternal symptoms during pregnancy, by investigating cross-cohort consistency, and by investigating whether parental symptoms in early childhood may…

High and stable levels of aggression and the presence of aggressive behaviour in multiple settings according to different informants are risk factors for later problems. However, these two factors have not been investigated in early childhood. The present study investigates trajectories of parent-reported child aggression from 1.5 up to 6 years of…
