Because exposure to traumatic stressors is part of the expected work experience of some occupations (e.g., military personnel and emergency services workers), it is sensible to make efforts to prepare individuals in these professions for their encounters with traumatic events. This preparation is not explicitly undertaken in most workplaces, with some exceptions (e.g., some military training environments). To date, research has not examined our capacity to prepare individuals or communities for trauma exposure. However, general principles of preparation can be outlined that are consistent with theoretical models of the development of PTSD, research on risk factors for development of PTSD, and emerging concepts of
resilience and hardiness.
