How A Gratitude Intervention Influences Workplace Mistreatment: A Multiple Mediation Model

Despite wide-ranging negative consequences of interpersonal mistreatment, research offers few practical solutions to reduce such behavior in organizations. Given that interpersonal relationships are strengthened and desired employee behaviors are more frequent when individuals purposefully cultivate feelings of gratitude, the present study tests the effectiveness of a 10-day gratitude journaling intervention in reducing workplace incivility, gossip, and ostracism. Because research has not examined the mechanisms by which gratitude interventions influence outcomes, we draw on theory and research from the gratitude literature to propose and test a multiple mediator model. Specifically, we examine the moral affect theory of gratitude, find-remind-and-bind theory, self-regulation theory, and social exchange theory as possible explanations for the effects of the intervention. Two field experiments involving 147 (Study 1) and 204 (Study 2) employees demonstrated that the intervention decreased mistreatment (as reported by coworkers) by enhancing self-control resources. We also found that the effects of the intervention were stronger for individuals who perceive higher norms for gratitude in their workplace. The findings support the resource-building nature of gratitude interventions and demonstrate that a gratitude intervention is one effective way to decrease interpersonal mistreatment in organizations. Implications for theory and practice are discussed.
