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 e

The 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.

In this sample, we found that, for children, family income and parental education when entering preschool were significant predictors of mental health problems after elementary school enrollment; in particular, low income and low maternal educational achievement predicted a high probability of the development of a psychiatric disorder. A greater understanding of the mechanisms of these associations could contribute to improvements in interventions aimed at preventing child maladjustment.

These findings suggest that destructive and constructive marital conflict may directly and indirectly influence children's social skills development through the mediation of parenting practices.

Japan has the highest life expectancy in the world. However, this does not guarantee an improved quality of life. There is a gap between life expectancy and healthy life expectancy. This study aimed to reveal the features of healthy life expectancy across all secondary medical areas (<i>n</i> = 344) in Japan and examine the relationship among healthcare resources, life expectancy, and healthy life expectancy at birth. Data were collected from Japan's population registry and long-term insurance r

Social and emotional learning programs in classrooms may effectively control problem behaviors in early childhood and prevent school maladjustment. A whole-class approach can reach more children, maximizing the preventive effects. The program can improve academic performance and social adaptation, contributing to the long-term development of psychological health and social skills. Nevertheless, further longitudinal research is required to assess the program's long-term effects. In summary, stren

The results suggest that deterioration in sleep quality, sleep difficulties, daytime arousal difficulties, and sleep disturbances may increase the risk of behavioral problems in adolescents.

The participation of women with young children in the Japanese labor force has increased dramatically in recent years, bringing growing potential for conflict between work and family roles amid inadequate social systems, such as childcare support. Thus, work-life balance (WLB) of mothers may influence their children's mental health and lifestyle. This study aims to clarify the relationship between parents' WLB and children's mental health, as well as the underlying factors of parental stress and

The results of this study suggest that direct parental assistance for PA such as logistic support encourages children to engage in moderate-to-vigorous PA; in addition, parental use of community resources may encourage children to engage in moderate and light PA such as walking. Conversely, indirect and negative involvement such as modeling and limiting sedentary activities were not associated with children's PA. Therefore, logistic support may need to be strengthened to encourage moderate-to-vi

This study reveals that interparental conflict is associated with children's behavioral problems. Constructive marital conflict was significantly inversely associated with externalizing and internalizing problems in both boys and girls. Meanwhile, destructive marital conflict (i.e., avoidance-capitulation and verbal aggression) was significantly positively associated with externalizing problems in boys and significantly positively associated with internalizing problems in girls. These findings c

This study examines the effectiveness of a community center in Japan at promoting social participation and sustaining its regular users' functional capacity. The surveys were distributed to 108 physically and cognitively independent local older people; 72 responses were received. There were 16 regular users and 56 nonregular users. An inverse probability of treatment-weighted Poisson regression analysis was performed, and prevalence rate ratios were computed for social participation and function

These findings suggest that mother's SOC may directly as well as indirectly influence children's social skills development through the mediating effect of childrearing. The results offer preliminary evidence that focusing on support to improve mothers' SOC may be an efficient and effective strategy for improving children's social skills development.

Healthy life expectancy was negatively associated with characteristic geriatric symptoms, with strong associations with frailty, physical functional decline, and depression. Therefore, comprehensive assessment and prevention of geriatric symptoms may increase healthy life expectancy.

Abstract Consistent daily routines are associated with children’s well-being. Family routines provide both a predictable structure to guide behavior and an emotional environment that supports development. Enforcing family routines, improving family relationships, and creating a healthy home environment are necessary to maintain children’s psychosocial health. This study examined the associations between family routines, family relationships, and elementary school children’s behavior. Parents of
