Fatigue is associated with numerous harmful physical and mental health outcomes. Despite the established relationship between sleep and fatigue, research examining sleep variability within a person (i.e. intraindividual variability; IIV) and fatigue is limited. In addition, the associations between child and parent sleep regarding parent fatigue…

Deficits in language skills are a risk factor for later aggressive behaviour. However, previous research has mainly addressed clinical or high-risk samples and relations between language and aggressive behaviour in preschoolers and children in primary school. Based on a German longitudinal project with N = 547 typically developing children, the…

Because parents of children with cerebral palsy encounter many challenges, the quality of their parenting varies substantially across time. To understand how and why their parenting behaviors change across time, we examined the contributions of child behavior and parents' psychological needs to explanations of yearly variation in responsive,…

The current study examines the extent to which associations between internalizing problems, body mass index (BMI), and language skills from early (36 months) to late childhood (fifth grade) are due to relatively stable between-child differences, time-specific correlations, or cross-lagged paths. Data from the NICHD study, Early Child Care and…

The COVID-19 pandemic profoundly affected American families and children, including through the closure or change in the nature of their care and school settings. As the pandemic has persisted, many children remain in remote schooling and those attending in-person childcare or school have contended with unpredictable closures. This study…

The COVID-19 pandemic has presented families around the world with extraordinary challenges related to physical and mental health, economic security, social support, and education.

Posttraumatic growth theory posits that when life circumstances are perceived as stressful, secondary appraisal processes can be recruited in ways to facilitate both coping efforts and personal growth. Using a mixed-methods approach, we found mothers' most challenging experiences involved child behavior (e.g. aggression, communication, and social…

This study aims to reveal the meanings attached to the concept of childhood and discuss how it is conceptualized and shaped with cultural attributes by parents and preschool teachers. The study was based on both quantitative and qualitative stance. One hundred and thirty parents and 125 preschool teachers participated in the first phase of the…

We explored the factors associated with the stress signs among children during the COVID-19 pandemic in Japan. Although children showed increased stress signs, they also showed increased development of good behavioral traits during this period. Parenting styles were significantly correlated with the psychological and physical stresses experienced…

Children who bully have learned to use their power and aggression to control others, a mode that is not conducive to healthy relationships either in the present or in their future lives. Furthermore, there is evidence that children who bully are also likely to have mental health problems that persist into adult life. There are also wide social and…

Purpose: The purpose of the study was to identify major symptom domain variables common to child trauma and create a prototype short trauma symptom screening tool (STST) intended for use in pediatric medical settings. Methods: This manuscript describes the first two phases of an on-going prospective mixed-method instrument development study. Phase…

Clinically meaningful behavior problems are thought to be present beginning in the early toddler years, yet few studies have investigated correlates of behavior problems assessed before age 2 years. The current study investigated the direct and interactive contributions of early infant and caregiver characteristics thought to play an important…

This exploratory longitudinal study examined behavioral outcomes and parenting stress among families with children adopted from foster care, taking into account environmental and biological risk factors. Child internalizing and externalizing problems and parenting stress were assessed in 82 adopted children and their families at 2 months…

Research has demonstrated mixed results regarding differences in social and emotional characteristics between gifted and typical populations. The purpose of this secondary analysis of data from the Early Childhood Longitudinal Study: Birth Cohort (ECLS-B) is to investigate the affective characteristics of early mathematics and literacy ability…

Extant research has highlighted the importance of multiple characteristics of housing but has not comprehensively assessed a broad range of housing characteristics and their relative contributions to children's well-being. Using a representative, longitudinal sample of low-income children and adolescents from low-income urban neighborhoods (N =…
