Disturbed grief, operationalized as persistent complex bereavement disorder (PCBD), correlates with yet differs from posttraumatic stress disorder (PTSD) and depression symptoms. However, knowledge about temporal associations among these symptoms is limited. We aimed to enhance our understanding of the etiology of loss-related distress by examining temporal associations among PCBD, PTSD, and depression symptom levels. Dutch people (N = 172) who lost significant other(s) in a plane disaster completed questionnaires for PCBD, PTSD, and depression 11, 22, 31, and 42 months after the disaster.
