Objective: It has been suggested that both low iron and zinc levels might be associated with Attention Deficit Hyperactivity Disorder (ADHD) symptoms. However, the association of zinc and iron levels with ADHD symptoms has not been investigated at the same time in a single sample. Method: 118 subjects with ADHD (age = 7-14 years, mean = 9.8,…

This study examined whether physical activity, mental health and socio-economic position were associated with the overall academic performance and future educational plans of adolescents aged 15-16 years. We used a sample of 7002 boys and girls from the Northern Finland Birth Cohort 1986. Data were collected by a postal enquiry in 2001-02.…

Analogue behavioral observation of structured parent-child interactions has often been used to obtain a standardized, unbiased measure of child noncompliance and parenting behavior. However, for assessment information to be clinically relevant, it is essential that the behavior observed be similar to that which the child normally experiences and…

Much research has argued for the existence of a marriage benefit to men, women, and children. Although the commonly suggested current response to a husband's violence has been for the couple to separate, traditionally women were often told to "stay for the children." This paper uses the Project on Human Development in Chicago…

This study examined the longitudinal relations between competence (academic achievement and social preference) and problem behavior (loneliness and aggression) in 741 elementary school boys and girls in the Netherlands (Grades 1-5). Also, we examined the moderation effects of having no friends, aggressive friends, or nonaggressive friends on the…

Effortful control (EC) is an important developmental construct, associated with socioemotional growth, academic performance, and psychopathology. EC is defined as the ability to execute goal-directed behavior to inhibit or delay a prepotent response in favor of a subdominant response. Extant research indicates that EC may be multidimensional.…

Background: Childhood behavior problems are associated with premature mortality. To identify plausible pathways that may account for this association, we explored the extent to which childhood behavior problems relate to health behaviors and health outcomes at midlife. Methods: The Aberdeen Children of the 1950s (ACONF) study comprises 12,500…

The aim of this study was to test whether negative cognitive errors (overgeneralizing, catastrophizing, selective abstraction, and personalizing) mediate the moderator effect of non-verbal cognitive ability on the association between adverse life events (life stress) and emotional and behavioral problems in adolescence. The sample consisted of 430…

The prevalence of and risk factors for aggression were examined in 1,380 children and adolescents with autism spectrum disorders (ASD). Prevalence was high, with parents reporting that 68% had demonstrated aggression to a caregiver and 49% to non-caregivers. Overall, aggression was not associated with clinician observed severity of ASD symptoms,…

Background: While there is considerable evidence of income gradients in child and adolescent behaviour problems, evidence relating to children and young people's emotional difficulties is more mixed. Older studies reported no income differentials, while recent reports suggest that adolescents from low-income families are more likely to experience…

Dyadic shared-reading and oral storytelling practices and their association to American preschoolers' (N = 33) prosocial and problem behaviour was examined. The frequency (how often dyads read) and history (the child's age at first reading) were examined within shared-reading; emotion state talk and evaluative judgments were examined in both…

Mother-child play of maltreating and nonmaltreating families was analyzed when infants were 12 months old (Time 1), and 2 years old (Time 2), as a context to examine children's developing cognitive and social skills. At Time 1, infants from abusing families demonstrated less independent and more imitative behavior during play than did infants from…

The current study examined concurrent and longitudinal relations between maternal negative affective behaviour and child negative emotional expression in preschool age children with (n=96) or without (n=126) an early developmental risk, as well as the predictions of later behaviour problems. Maternal negative affective behaviour, child…

This 3-year longitudinal study investigated the associations of student (aged 9 to 10 years at the beginning of the study; n = 281; 51% girls) participation in extracurricular activities with teacher-rated socioemotional behavior and school achievement. MANOVA results showed that, after controlling for the grade level and the initial level of the…

Many children exhibit challenging behavior even in preschool. Recent reports have suggested that behavior problems, language skills, and academic delays are interrelated and perhaps mutually causal mechanisms, each adversely influencing the other. Language difficulties lead to behavior problems, behavior problems lead to academic delays, and…
