Abstract

Although work tasks often address substantive social issues, the effects of issue characteristics on task motivation are little understood. This study explores this topic by examining how the moral characteristics of an issue (moral intensity) affect motivation in tasks intended to address the issue (task motivation). Adopting the lens of work design theory, I hypothesize that moral intensity increases task motivation through the mediation of perceived task impacts on the community (perceived community impacts), and that this effect will occur after controlling for the effects of perceived task impact on the worker and their organization. In two studies in the context of volunteering I find that, rather than acting in parallel with other task impacts, the effect of moral intensity through perceived community impacts is fully mediated by perceived organization and self impacts in a three-stage mediation. These findings demonstrate the potential relevance of issue characteristics such as moral intensity to work design theory and shed new light on the psychological mechanisms through which perceived prosocial impacts promote task motivation. I discuss implications for research and practice.
