Trauma-Related Sleep Problems And Associated Health Outcomes In Police Officers: A Path Analysis

Police officers are frequently exposed to two different types of potentially traumatic events: one dealing with physical threats to self and the other involving the witnessing of harm to others. These different types of traumatic experiences are thought to produce various posttraumatic reactions. Furthermore, sleep problems are also reported as a hallmark of posttraumatic stress disorder. There is evidence, however, that sleep problems may mediate the relationship between posttraumatic stress disorder symptoms and health outcomes, especially physical health and depression. Previous research has shown this to be the case among officers from large urban agencies. The purpose of the present study was to test a model involving a pathway from trauma type and posttraumatic stress disorder symptoms to physical health and depression that is mediated by sleep quality in officers (N = 193) using data from small- to mid-size police agencies. Results revealed that sleep problems served as a mediator between posttraumatic stress disorder hyperarousal and avoidance symptoms and health outcomes, that the trauma types are related to different posttraumatic stress disorder symptoms, and that complicated relationships exist between the study variables. In addition, the results indicated that approximately 25% of our sample displayed probable partial posttraumatic stress disorder or probable full posttraumatic stress disorder, causing substantial functional impairment. Suggestions for improving officer health and performance in the field are provided. Specifically, it appears that interventions designed to address posttraumatic stress disorder hyperarousal symptoms related to personal life threat and the posttraumatic stress disorder avoidance symptoms related to the witnessing of human suffering may maximize officer sleep quality and ultimately overall wellness. In particular, mindfulness-based interventions are well suited for addressing these symptom clusters.
