Armed conflict is associated with significant long-term psychiatric morbidity. Interventions to reduce the incidence of psychiatric disorder following psychological trauma may be classified into three categories. Primary prevention includes the selection, preparation and training of individuals likely to be exposed to potentially traumatizing events. Secondary prevention comprises a variety of brief psychological techniques immediately or shortly after traumatizing life events, the best known of which is Psychological Debriefing. Tertiary interventions comprise the treatment of established PTSD and others. Psychiatric morbidity was studied in 106 British soldiers returning from UN peace-keeping duties in the former Republic of Yugoslavia. All 106 soldiers received an Operational Stress Training Package prior to their deployment and a randomly selected group also received a post-operational PD. Very low rates of PTSD and other psychopathology were found overall and the Operational Stress Training Package may have contributed to this. Elevated CAGE scores suggestive of significant alcohol misuse were observed in both groups and chemical avoidance behaviours arising from this may have masked psychopathology. CAGE scores diminished significantly in the debriefed group by the end of the follow-up period suggesting that PD may have been of benefit despite the apparent absence of PTSD. This study also demonstrates that a high incidence of psychiatric morbidity is not an inevitable consequence of military conflict.

The efficacy of critical incident stress debriefing (CISD) and psychological debriefing (PD) following potentially traumatising events has recently been challenged after a number of recent randomised controlled trials (RCTs) failed to demonstrate that CISD or PD prevents or reduces the incidence of posttraumatic stress disorder (PTSD). These studies have used measures of PTSD as the principal outcome and have generally not measured comorbid psychopathology, behavioral or social dysfunction. In a recent RCT of group debriefing amongst British soldiers returning from peacekeeping operations in Bosnia, PD had a significant effect in reducing a worrying level of alcohol misuse in the sample. The findings of this study suggest that that it is premature to conclude that debriefing is ineffective and that a broader range of outcome measures should be employed in future trials of debriefing.

These findings show that a psychological debriefing following a series of traumatic events or experiences does not appear to reduce subsequent psychiatric morbidity and highlights the need for further research in military and civilian settings.

On 2 August 1990 Iraq invaded Kuwait and held hostage all its inhabitants. Amongst those forced to stay were 71 British servicemen and their families who were held hostage for up to four and a half months. This study investigated the mental health status of this group of individuals at 6 and 18 months after the final hostage was released. Participants completed the Impact of Event Scale and the 28-item version of the General Health Questionnaire at both 6 and 18 months. In addition they completed a questionnaire regarding background factors, the dimensions of the trauma and the effects of their hostage experience. The Impact of Event Scale scores changed little over time whereas the General Health Questionnaire scores reduced significantly (p = .001) over the 12-month period suggesting that despite ongoing intrusive and avoidance phenomena levels of psychological distress did reduce. Those variables most strongly associated with a poor psychological outcome were witnessing physical violence and perceived deterioration in physical and mental health. Poor outcome at 6 months was strongly correlated with poor outcome at 18 months.
