<p>This study´s objective was to analyze the mediating effects of hardiness, hope, and vitality in the relationship between future time perspective and self-efficacy in the work context. We also analyzed whether such mediation effects vary between Mexico and the U.S. A total of 583 MBA students were surveyed in both countries. The PROCESS (Hayes, 2013) command in SPSS® (20) was employed to analyze the data. The results suggest that (in order of mediating power) hope, hardiness, and vitality transmit almost all the future time perspective´ effects to self-efficacy and that such mediating effects are invariant between the analyzed countries.</p>
