Sleep quality problems three decades post-disaster

AbstractStudy objectives: Sleep quality problems are a core feature of posttraumatic stress disorder (PTSD). The aims of this study were to describe and evaluate possible differences regarding sleep quality problems and hyperarousal symptoms between exposed and unexposed survivors after an avalanche. Further, we wanted to describe any association between avalanche exposure and survivors’ self-reported sleep quality problems and posttraumatic stress (disorder) symptoms with and without hyperarousal symptoms.Method: The participants were soldiers who had survived an avalanche (n = 12) and a sample of unexposed soldiers (n = 9). Subjective sleep quality problems and posttraumatic stress (disorder) symptoms were assessed using well-validated measures: Pittsburgh Sleep Quality Index (PSQI), Posttraumatic Symptom Scale-10 (PTSS-10), and Impact of Event Scale-15 (IES-15). Hyperarousal symptoms were assessed using a 3-item hyperarousal-index from PTSS-10 (PTSS-10/Hyp index).Results: No significant difference in s...
