Abstract

Employees are getting less sleep, which has been shown to deplete self-regulatory resources and increase unethical behavior (Barnes, Schaubroeck, Huth, & Ghumman, 2011; Christian & Ellis, 2011). In this study, we extend the original mediated model by examining the role of 2 moderators in the relationship between sleep deprivation, depletion, and deceptive behavior. First, we derive psychological arguments from the psychopharmacology literature to hypothesize that caffeine moderates the relationship between sleep deprivation and depletion by replenishing self-regulatory resources. Second, we draw from recent research in social psychology to hypothesize that social influence moderates the relationship between depletion and deceptive behavior, such that depleted individuals are less able to resist the negative influence of others. Results of a laboratory study provide support for our expanded model combining mediation and moderation, adding to our understanding of the role of sleep deprivation in the incidence of workplace deception.
