Daily survey study demonstrates that nightly work-family conflict increases unsafe morning commute hard braking in workers, highlighting across-day spillover risks to driver safety.
Key Points
To examine how nightly work-family conflict at home transmits across days to impair next-morning commute safety via sleep quality and emotional affect.
Conducted a 2-week daily survey study tracking employees across consecutive workdays (N = 50).
Combined daily self-reported surveys of work-family conflict, sleep, and affect with objective vehicle telemetry measuring hard braking during morning commutes.
Higher nightly work-family conflict was associated with poorer nightly sleep quality.
Impaired sleep quality subsequently diminished next-morning positive affect, which directly predicted an increase in pre-work commute hard-braking events.
