Input: Ten studies were included in the review but only five reported data that could be used. Three of the ten studies were related to exercise-based psychological interventions. Seven were related to psychological interventions. No meta-analyses were possible due to diversity of participants, interventions and outcomes. Two studies compared a psychosocial intervention versus another intervention. Three studies compared a psychosocial intervention to a control group. Only one primary prevention trial reported data for the primary outcomes and, although this study found a significant difference in depression in favour of the intervention at endpoint, this difference was no longer evident at 18 months. No studies of primary prevention comparing different interventions and reporting primary outcomes of interest were identified. The methodological quality of the included studies was summarised. No study met our full quality criteria and one was regarded as low-quality. The remainder could not be rated because of incomplete data in the published reports and inadequate responses from the trialists. There is evidence only from individual small and low quality trials with minimal data suggesting that police officers benefit from psychosocial interventions, in terms of physical symptoms and psychological symptoms such as anxiety, depression, sleep problems, cynicism, anger, PTSD, marital problems and distress. No data on adverse effects were available. Meta-analyses of the available data were not possible. Further well-designed trials of psychosocial interventions are required. Research is needed on organization-based interventions to enhance psychological health among police officers.
Output:

In view of the importance of the functions performed by law enforcement officers, and the fact that there is no definitive approach to deal with psychological problems they may develop, a systematic review of the evidence is needed to determine the effectiveness of psychosocial interventions in preventing these problems in this select population. We found ten randomised trials, but not of all these contributed useful data for this review and quantitative meta-analyses were not possible. No data on adverse effects were available. The available evidence is, therefore, limited to the analysis of single, small and low quality trials. This suggests that police officers may benefit from psychosocial interventions in terms of psychological symptoms and physical symptoms. Further well-designed trials of psychosocial interventions to enhance the psychological health of police officers are required. Trials of organisation-based interventions are also needed.
