There is a sharp rise in depressive moods from childhood to adolescence. Since moods can cross over from a child to a parent and spill over from family to work, offspring's temporary feelings of depression represent potential risks for parents' occupational health and well-being. In the current study, the authors investigate the impacts of offspring's temporary feelings of depression on mothers' work engagement via the transfer of negative moods, and on fathers' work engagement via the transfer of positive moods. Participants were 265 full-time employees and their adolescent offspring. The results confirmed our hypotheses. Offspring's temporary feelings of depression were associated with less maternal work engagement via increased maternal negative moods and endangered paternal work engagement via decreased paternal positive moods. The finding implies that negative emotions may be related to the occupational health of working mothers, while positive emotions may be related to the occupational health of working fathers.
