Supervisor Support Buffers Daily Psychological and Physiological Reactivity to Work-to-Family Conflict

Using a daily diary design, the current study assessed within-person associations of work-to-family conflict with negative affect and salivary cortisol. Furthermore, the authors investigated whether supervisor support moderated these associations. Over 8 consecutive days, 131 working parents employed by an information technology company answered telephone interviews about stressors and mood that occurred in the previous 24 hours. On Days 2-4 of the study protocol, they also provided 5 saliva samples throughout the day that were assayed for cortisol. Results indicated a high degree of day-to-day fluctuation in work-to-family conflict, with employed parents having greater negative affect and poorer cortisol regulation on days with higher work-to-family conflict compared to days when they experience lower work-to-family conflict. These associations were buffered, however, when individuals had supervisors who offered support. Discussion centers on the use of dynamic assessments of work-to-family conflict and employee well-being.
