RESUMO
In today's highly competitive and extremely complex global economy, organizational leaders at all levels are facing unprecedented challenges. Yet, some seem to be handling the pressure better than others. Utilizing 4 samples of CEOs/presidents/top (n = 205), middle (n = 183), and junior (n = 202) managers, as well as 107 entrepreneurs, using Structural Equation Modeling we tested the direct effect that their level of mindfulness (heightened awareness) and the mediating effect of their psychological capital (i.e., hope, efficacy, resilience, and optimism) may have on their mental well-being. In all 4 samples, mindfulness was found to be negatively related to various dysfunctional outcomes such as anxiety, depression, and negative affect of the managerial leaders and burnout (i.e., emotional exhaustion and cynicism) of the entrepreneurs. For all 4 samples, the model with psychological capital mediating the effects of mindfulness on dysfunctional outcomes fit the data best. The study limitations, future research and practical implications of these findings conclude the article.
