Abstract: As the Army continues to adapt to evolving mission demands and global threats, those who execute the mission – both soldiers and Department of the Army (DA) civilians – must also adapt to changing occupational demands and requirements. Occupational stress within the military community is a threat to health and wellbeing that impacts not only individual soldiers and civilian personnel, but also units, families, and the broader military community. Hardiness is an operational requirement for military success, spirituality might be a means to positively impact soldier and DA Civilian hardiness. This study sought to understand the relationship between spirituality and hardiness within the Army, which included data collected from U.S. Army soldiers (N=313) and DA Civilians (N=276). We hypothesized that increased individual spirituality have a direct relationship with the positive aspects of hardiness and an inverse relationship with the negative aspects of hardiness as defined by the dual process model of hardiness. Employing regression analysis, empirical support was found to support our hypotheses for relationships between spirituality and hardiness variables, with increased spirituality relating to increased positive hardiness and decreased negative hardiness traits. Military leaders can use that knowledge to develop and test targeted interventions that may help to increase positive hardiness and decrease negative hardiness in the Army. Further, Holistic Health and Fitness programming may benefit from improved psychological function by incorporating training that integrates hardiness and spirituality concepts.
