The moderating effect of perceived organizational support on the relationships between organizational justice and objective measures of cardiovascular health

This paper builds on a recent meta-analytic review on the relationships between organizational justice and health. Specifically, we examine the moderating role of perceived organizational support (POS) on the relationships between organizational justice and three objective cardiovascular health measures, namely, heart rate, systolic blood pressure, and diastolic blood pressure, among a population of 290 public construction workers. The interaction between justice and POS was statistically significant using procedural justice, demonstrating that procedural justice is associated with improvements in the three health outcomes only when POS is relatively high. In other words, higher levels of both procedural justice and POS were needed for reduced heart rate and reduced systolic and diastolic blood pressure. However, the interaction between distributive justice and POS did not significantly relate to the health outcomes. This study makes a contribution to the field by focusing the effects of psychosocial workplace variables on measures of cardiovascular health, and demonstrating an important boundary condition of the relationships between procedural justice and cardiovascular risk factors.
