The time that children spend using digital devices is increasing rapidly with the development of new portable and instantly accessible technology, such as smartphones and digital tablets. Although prior studies have examined the effects of traditional media on children’s development, there is limited evidence on the impact of mobile device use. The current study aimed to clarify the link between mobile device use and child adjustment. The sample included 1,642 children aged 6 in first grade at elementary schools in Japan. Parents completed a self-report questionnaire regarding their children’s use of mobile devices and emotional/behavioral adjustment. We performed inverse probability of treatment weighted (IPTW) logistic regression to compute odds ratios (OR) for emotional/behavioral problems according to mobile device use. The values for IPTW analysis were computed based on variables assessing sociodemographics and child characteristics. Among the participants, 230 (14.0%) were regular users (60 minutes or more on a typical day) and 1,412 (86.0%) non-regular users (under 60 minutes on a typical day). Relative to non-regular use, regular use of mobile devices was significantly linked to conduct problems (IPTW-OR: 1.77, 95% CI: [1.03–3.04], p < .05) and hyperactivity/inattention (IPTW-OR: 1.82, 95% CI: [1.15–2.87], p < .01). Based on these results, routine and frequent use of mobile devices appear to be associated with behavioral problems in childhood.

While ineffective discipline can be attributed to authoritarian and permissive parenting styles, little research has examined the role of gender in the association between parenting style and early childhood behavioral problems. Thus, this study aimed to clarify the effects of authoritarian and permissive parenting on children’s externalizing and internalizing behaviors during the preschool-to-elementary-school transition according to gender in Japan. A sample of 1668 Japanese children (853 boys and 815 girls) were followed longitudinally over one-year intervals, and assessed based on parenting styles (the Parenting Scale), children’s behavioral problems (the Strengths and Difficulties Questionnaire), and family characteristics. Multivariate analyses revealed that, when analyzed by gender, authoritarian discipline influenced externalizing problems in boys (β = 0.048, p = 0.047) and girls (β = 0.067, p = 0.023), while permissive discipline influenced externalizing problems in boys only (β = 0.049, p = 0.038). The results document the relationship between family processes and the development of disruptive behavior disorders in children. Support for parents employing such child-rearing styles in early childhood may be effective in reducing school maladjustment.

BackgroundThis study examined the pathways by which destructive and constructive marital conflict leading to social skills development in preschool children, are mediated through negative and positive parenting practices.MethodsMothers of 2931 Japanese children, aged 5–6 years, completed self-report questionnaires regarding their marital relationship (the Quality of co-parental communication scale) and parental practices (the Alabama parenting questionnaire). The children’s teachers evaluated their social skills using the Social skills scale.ResultsPath analyses revealed significant direct paths from destructive marital conflict to negative parenting practices and lower scores on the self-control component of social skills. In addition, negative parenting practices mediated the relationship between destructive marital conflict and lower scores on cooperation, self-control, and assertion. Our analyses also revealed significant direct paths from constructive marital conflict to positive parenting practices, and higher scores on cooperation and assertion. Positive parenting practices mediated the relationship between constructive marital conflict and higher scores on self-control and assertion.ConclusionsThese findings suggest that destructive and constructive marital conflict may directly and indirectly influence children’s social skills development through the mediation of parenting practices.

ObjectiveUsing a short-term longitudinal design, this study examined the concurrent and longitudinal relationships among familial socioeconomic status (SES; i.e., family income and maternal and paternal education levels), marital conflict (i.e., constructive and destructive marital conflict), parenting practices (i.e., positive and negative parenting practices), child social competence (i.e., social skills), and child behavioral adjustment (i.e., internalizing and externalizing problems) in a comprehensive model.MethodsThe sample included a total of 1604 preschoolers aged 5 years at Time 1 and first graders aged 6 years at Time 2 (51.5% male). Parents completed a self-reported questionnaire regarding their SES, marital conflict, parenting practices, and their children’s behavioral adjustment. Teachers also evaluated the children’s social competence.ResultsThe path analysis results revealed that Time 1 family income and maternal and paternal education levels were respectively related to Time 1 social skills and Time 2 internalizing and externalizing problems, both directly and indirectly, through their influence on destructive and constructive marital conflict, as well as negative and positive parenting practices. Notably, after controlling for Time 1 behavioral problems as mediating mechanisms in the link between family factors (i.e., SES, marital conflict, and parenting practices) and behavioral adjustment, Time 1 social skills significantly and inversely influenced both the internalization and externalization of problems at Time 2.ConclusionsThe merit of examining SES, marital conflict, and parenting practices as multidimensional constructs is discussed in relation to an understanding of processes and pathways within families that affect child mental health functioning. The results suggest social competence, which is influenced by the multidimensional constructs of family factors, may prove protective in reducing the risk of child maladjustment, especially for children who are socioeconomically disadvantaged.
