Mental health issues of peacekeeping workers.

The end of the Cold War has brought a dramatic change to the international political situation and the role of the United Nations peacekeeping operations (PKO) has drawn increased attention. While many reports on PKO have focused on political or sociologic considerations, the mental health of the peacekeepers themselves has received little attention and psychiatric problems that can have a negative impact on mission success have been largely ignored. Participation in PKO creates a number of stressors and serious psychiatric and/or physical disorders may result. Yet, there is little research on this topic, either domestically or globally, and the methodology for clinical intervention remains in an early stage of development. We have reviewed previous reports to determine how various stressors before, during and after deployment affect the participants. Research in associated fields (e.g. crisis workers and military personnel) are also reviewed and their application to peacekeeping psychiatry is discussed. It must be admitted that the significance of PKO is arguable and each PKO is unique in terms of the nature of its mission and the local situation. Yet, the relationship between the psychiatric status of the personnel and the characteristics of an individual mission has never been studied. At present, no clear consensus regarding a framework for psychiatric intervention exists. Studies that enhance the recognition and significance of peacekeeping psychiatry are likely to improve the efficacy of PKO.
