(2004) found that officers who were low in hardiness made more erroneous decisions compared with officers high on hardiness during simulated incidents. In military groups, hardiness has been identified as significant moderator of combat-exposure stress (Bartone, 1999(Bartone, , 2000, as well as leader performance (Bartone, Eid, Johnsen, Laberg, & Snook, 2009
Hardiness DevelopmentHardiness training programs have varied in complexity from relatively simple self-paced learning modules to more elaborate approaches that also include teachings on additional factors that can influence healthy and unhealthy reactions to stress. In one of the earliest reported efforts, In sum, there seems to be some empirical evidence suggesting that hardiness may be malleable to the effects of training initiatives. Many studies, however, are somewhat limited in 6 that they have utilized a relatively short time-frame with minimal post-intervention follow-up (for a more complete review, see . Using a short timeframe raises the possibility that some of the increases are learning effects due to test familiarization. In the study by Tierny and Lavelle (1997), for instance, levels of hardiness increased immediately following completion of the training, but returned to baseline levels six months later. Bartone and Hystad (2010) suggest that to create lasting effects, hardiness training may need to include regular follow-ups and re-training over an extended period of time. To the best of our knowledge, no studies so far have longitudinally investigated how individual levels of hardiness are influenced by long-term training interventions.
Hardiness Development and Military ExperienceBased on the discussion so far, the aim of this study was to longitudinally examine the showed that individual hardiness levels increased following completion of the training course.
