Recent research has suggested that hardiness protects wellness and stimulates effective functioning despite stressful circumstances. This study continued evaluation of the effectiveness of a hardiness training program. With managers as participants, the hardiness training condition was compared with a relaxation/meditation condition and a placebo/social support control. The hardiness training condition was more effective than the other 2 conditions in increasing self-reported hardiness, job satisfaction, and social support while decreasing self-reported strain and illness severity. This pattern of results furthers the importance of hardiness training in stress management.
