Development of a stepped care intervention model of evidence-based interventions for the management of posttraumatic stress in the Belgian Police.

Background: Police officers are frequently exposed to a wide variety of potentially traumatic events (PTE) and are therefore at a considerable risk of developing posttraumatic stress disorder (PTSD). Previous research estimated the point prevalence of PTSD in Belgian police officers at 7.4%, significantly higher than in the general population. An effective organisational strategy to manage posttraumatic stress is essential.Objective: We aimed to develop a novel organisational approach regarding traumatic stress for Belgian police, combining evidence-based strategies for the prevention and treatment of posttraumatic stress in a stepped care intervention model.Method: In a broad development process, we combined scientific literature, case studies of best practices from other police organisations with insights gathered from a number of expert panels, thematic working groups and feedback groups.Results: A comprehensive stepped care intervention model was developed, consisting of evidence-based interventions for the prevention and treatment of posttraumatic stress.Conclusions: The intervention model is a promising organisational strategy for the management of posttraumatic stress in police organisations based on evidence-based interventions. Its effectiveness will be studied in the coming years.
