How work spills over into the relationship: Self-control matters

This research investigated how and for whom experiences of the workday spill over into relationship functioning at home. Two correlational studies and one experimental study were conducted among Dutch dual‐earners with children. Moderated mediation analyses showed that work demands spill over into relationship behavior through the depletion of temporary self‐regulatory resources and subsequently a decrease in psychological availability for the partner. Whether work demands spill over into relationship behavior was dependent on dispositional self‐control in that evidence for negative spillover was only found for individuals low in dispositional self‐control. The experimental study showed that the induction of gratitude for the partner after the workday helped individuals low in dispositional control to prevent negative spillover into the partner relationship.
