Abstract

Luthans, Youssef, Sweetman, and Harms proposed a holistic approach to psychological capital that involves examining psychological capital and its effects across multiple life domains, including work, relationships, and health. This article focuses on the effects of psychological capital on objective health outcomes. Using data from a sample of 1,889 U.S. Army soldiers, we demonstrate that soldiers with higher levels of psychological capital prior to deployment were less likely to receive diagnoses for mental health problems and substance abuse postdeployment. In addition, the effects of psychological capital on mental health diagnoses were mediated by soldiers’ overall health perceptions.
