Longitudinal data from a large sample of twins participating in the Netherlands Twin Register (n = 42,827, age range 3-16) were analyzed to investigate the genetic and environmental contributions to childhood aggression. Genetic auto-regressive (simplex) models were used to assess whether the same genes are involved or whether new genes come into…

There is no current estimation about the impact of prematurity on a child's development in Lebanon.This study describes the developmental profile of 82 former preterm-born children aged between 2 and 8 years. The Wechsler Preschool and Primary Scale of Intelligence, third edition (WPPSI-III) and Achenbach Child Behavior Checklist (CBCL for ages…

Background: Previous research suggests that it is important to use parental reports when assessing children's anxiety, but it remains unclear to what extent there are differences between mothers' and fathers' scores and whether these potential differences have any repercussions for the psychometric properties of the scale being used. Objective:…

This study assessed the links between infant negative affect, parental reflective functioning (RF), and toddler behavior problems in a sample of 84 women and their infants. Mothers provided self-report demographic data and completed the Infant Behavior Questionnaire-Revised during a home visit when the infant was 7 months old. They also completed…

In order to shed more light on why referred girls are less likely to be diagnosed with autism spectrum disorder than boys, this study examined whether behavioral characteristics influence the probability of an autism spectrum disorder diagnosis differently in girls versus boys derived from a multicenter sample of consecutively referred children…

Challenging behavior in preschool can lead to harmful outcomes for some children. While interventions have been shown to be effective in reducing or eliminating challenging behavior, evidence suggests that young children with challenging behavior are under-identified for services, increasing their risk for expulsion from early childhood programs.…

Symptoms of autism spectrum disorder may influence alliance in psychotherapy. This study examined therapeutic alliance and its relationship with child characteristics and anxiety treatment outcomes in youth with autism spectrum disorder. Youth (N = 64) with autism spectrum disorder and co-occurring anxiety (7-16 years, IQ > 70) received 16…

This study examined dispositional and situational correlates of donating behavior in a sample of 221 eight-year-old children. Children were shown a promotional clip for a charity, including a donation call. For a random half of the children, the video fragment ended with a probe of a same-sex peer donating money to the charity. Seeing a peer…

The developmental significance of youths' racial identities during adolescence is well established. It is less clear how puberty, a normative process, influences the relationship between racial identity and adjustment outcomes during adolescence. This study examined whether puberty moderates the relationship between racial identity dimensions and…

This study examined two competing hypotheses regarding the moderators of the association between relational aggression and peer status in early adolescence. The "mitigation relational aggression" hypothesis examined whether positive social behaviors reduced the negative effects of relational aggression, thus amplifying the association…

Based on former research, it can be assumed that attachment relationships provide a context in which children develop both the effortful control (EC) capacity and the repertoire of responses to regulate distress. Both are important to understand children's (mal)adjustment. While the latter assumption has been supported in several studies, less is…

Internalizing problems are among the most common chronic psychological dysfunctions in childhood, yet the factors contributing to their emergence and persistence in preschool-aged children are still less understood. The contribution of specific individual variables (e.g. temperament), and that of proximal environmental factors, such as family…

No comprehensive studies have examined the utility of family drawings within the context of international adoption. We examined the relationship of Kinetic Family Drawings by 54 internationally adopted children in the USA (65% female; M age = 8.57 years, SD = 2.1) to demographics, child competencies (Child Behavior Checklist: CBCL/6-18) and…

The results obtained by adolescents with autism spectrum disorder were compared with those of typically developing girls and boys. Correlations between parents' and adolescents' ratings…

Studies have found that low marital satisfaction, parenting stress, and child behavior problems are linked in families of children with developmental delays (DD). However, previous investigations examining the relationships between parenting stress, child behavior problems, and marital satisfaction rarely examine the interrelationships of these…
