[영문]The mismatch between employed parents’ work schedules and their children's school schedules creates the structural underpinning for an as-yet-unstudied stressor, namely, parental after-school stress, or the degree of parents’ concern about their children's welfare after school. We estimate the relationship between parental after-school stress and psychological well-being in a sample of 243 employed parents of children in grades K?12. Parental after-school stress is related to psychological well-being. This relationship did not differ by parent gender or child age but was significantly stronger for parents of girls versus boys. Our results suggest that parental after-school stress is an important stressor that affects the well-being of a large segment of the work force and warrants further research.
