Lost Control Driving Home: A Dual-Pathway Model of Self-Control Work Demands and Commuter Driving

This research contributes to theory on self-control at work through applying and extending the limited-capacity model of self-control to examine the extent to which daily self-control work demands predict self-control failure and driving behavior during the commute after work. We develop a dual-pathway model in which resisting-distractions demands and impulse-control demands at work have unique relationships with speeding behavior via two separate pathways of self-control failure: one reflecting a failure to regulate attention and the other reflecting a failure to suppress impulses, which is moderated by negative affect. In two studies of daily work experiences and driving behavior, we find support for our model, over and above the effects of cognitive and affective work demands, postwork fatigue, and motivation. We discuss the implications of our findings in relation to the concept of self-control work demands and self-control depletion theory. Our findings also contribute to research on the links between work and commuting, and driving commuting most specifically, which is important because work-to-driving spillover represents a substantive safety issue for organizations.
