Sleep quality in complicated grief

J Trauma Stress. 2005 Aug;18(4):343-6. doi: 10.1002/jts.20035.


The aim of the present study was to evaluate severity of sleep disturbances in a group of 105 individuals presenting with complicated grief (CG) accompanied or not by comorbid depression and/or posttraumatic stress disorder (PTSD). A sample of 105 adults meeting criteria for CG was included in this study. All completed the Pittsburgh Sleep Quality Index (PSQI). The total sample presented a mean global PSQI score of 9.44, indicating overall poor sleep quality. Comorbid depression, but not PTSD, further worsened sleep quality. Further studies are required to investigate the potential role of poor sleep quality as a modifiable risk factor of complicated grief response.
