Abstract
Sleep disturbances are common following bereavement and are associated with several adverse mental and physical health outcomes. However, limited research has examined which sociodemographic and loss-related characteristics are associated with sleep problems in bereaved individuals. Identifying such characteristics may facilitate early monitoring and intervention to prevent the worsening of sleep problems. The present study aimed to shed light on concurrent predictors of sleep quality and insomnia symptom levels in a sample of 293 adults who experienced bereavement within the past ten years. Sociodemographic variables (age, sex, education level) and loss-related variables (relationship to the deceased, cause of death, and expectedness of death) were examined as predictors of sleep quality and insomnia symptom levels using simple and multiple linear regression analyses. Sleep quality was assessed using the Pittsburgh Sleep Quality Index, and insomnia symptom levels were measured with the Insomnia Severity Index. Univariate analyses indicated that lower educational attainment, less expected death, and older age related to poorer sleep quality. Furthermore, univariate analyses showed that lower education and less expected death were related to higher insomnia symptom levels. In multivariate models, education level remained a significant predictor of both sleep quality and insomnia symptoms, and expectedness of death remained a significant predictor of sleep quality. Future studies are needed that use longitudinal designs, objective sleep measures, and simple random sampling to strengthen and extend these findings.
