ABSTRACT
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 nurturing attitude. The study is based on a questionnaire survey administered in 2019 to fifth-grade elementary school students and their caregivers in Aichi Prefecture, Japan. The regression results indicated that the higher the work-family negative spillover, the higher the child's externalizing and internalizing problems, and the higher the positive spillover, the lower the problems and the higher the prosocial behaviors. Path analysis indicates that maternal WLB is negatively and positively related to children's behavior through maternal stress and parenting practices. The study suggests that maternal WLB is related to children's emotional and behavioral problems. WLB may impact children's emotional and behavioral problems through parents' mental health and involvement with their children, particularly because of work arrangements changing with the COVID-19 pandemic.
