Work-family Conflict, Family-supportive Supervisor Behaviors (fssb), and Sleep Outcomes Running Head: the Work-family Interface and Sleep 2 Author Note

Although critical to health and well-being, relatively little research has been conducted in the organizational literature on linkages between the work-family interface and sleep. Drawing on Conservation of Resources theory, we use a sample of 623 information technology workers to examine the relationships between work-family conflict, family-supportive supervisor behaviors (FSSB), and sleep quality and quantity. Validated wrist actigraphy methods were used to collect objective sleep quality and quantity data over a one week period of time, and survey methods were used to collect information on self-reported work-family conflict, FSSB, and sleep quality and quantity. Results demonstrated that the combination of predictors (i.e., work-to-family conflict, family-to-work conflict, FSSB) was significantly related to both objective and selfreport measures of sleep quantity and quality. Future research should further examine the workfamily interface to sleep link and make use of interventions targeting the work-family interface as a means for improving sleep health.
