BACKGROUND Although the prevalence of bully/victim problems in school-age children and adolescents has been investigated in many countries, only a few studies have been carried out among younger children. This study examines social behaviors and peer relationships of children involved in bully/victim problems in kindergarten. METHODS Three hundred and(More)
OBJECTIVE Theories of health behavior are usually tested on the between-person level. Associations between variables on the between- and the within-person level, however, can differ substantially. Thus, in order to better understand intrapersonal processes in the domain of health behavior, studies applying within-person analyses are needed. This study(More)
The current cross-sectional study investigated basal and stress-challenged hypothalamic-pituitary-adrenocortical (HPA) system function in 102 five-year old kindergarten children (59 boys, 43 girls) who had been assessed by a comprehensive psychological and behavioral test battery. Baseline HPA system activity was significantly increased in girls when(More)
BACKGROUND Cyber-bullying (i.e., bullying via electronic means) has emerged as a new form of bullying that presents unique challenges to those victimised. Recent studies have demonstrated that there is a significant conceptual and practical overlap between both types of bullying such that most young people who are cyber-bullied also tend to be bullied by(More)
OBJECTIVE The aim of this study was to investigate the associations between children's difficulties (conduct problems, hyperactivity/impulsivity, and emotional symptoms) and peer victimization and rejection in kindergarten. For the assessment of children's difficulties, the authors used a multi-informant approach. METHOD A total of 153 five-year-old(More)
BACKGROUND Various studies of adult endocrinology and sleep show close connections between poor sleep quality, deterioration of the HPA axis and negative psychological characteristics. However, the extent to which these associations may have already emerged and developed in childhood remains unclear. METHODS A total of 82 preschoolers (age 4.91+/-0.48)(More)
OBJECTIVES In children, objective data carried out from sleep EEG monitoring are scarce. Furthermore, results associating the hypothalamic-pituitary-adrenocortical (HPA)-activity with sleep EEG measurements in children are missing. Therefore, our study aimed to investigate in preschool-children the association between sleep patterns and endocrine activity.(More)
A summary of current knowledge on successful responses to cyberbullying differentiating between three different response domains: reducing risks, combatting the problem, and buffering negative impact. A systematic literature search yielded thirty-six relevant studies, most of which report findings regarding general prevention strategies (e.g., anti-bullying(More)
BACKGROUND Depressive symptoms in children are associated with social skills deficits and problems with peers. We propose a model which suggests different mechanisms for the impact of deficits in self-oriented social skills (assertiveness and social participation) and other-oriented social skills (pro-social, cooperative and non-aggressive behaviors) on(More)
The transition to parenthood is often accompanied by depression and stress. Several studies have established risk factors for postpartum depression, e.g., antenatal depression. However, only a few studies have involved fathers. Moreover, most studies focus on the prevalence of depression instead of intraindividual changes over time. Our study investigated(More)
