Rationale: Family members of patients who die in an intensive care unit (ICU) are at heightened risk of post-traumatic stress disorder (PTSD) symptoms. Not all surrogates develop these symptoms and heterogeneity exists in PTSD symptom clusters. Objectives: The study tested a personality model of PTSD symptoms in bereaved family caregivers of ICU patients. ⋯ Key Message: Family members who experience the death of a loved one following ICU treatment are vulnerable to PTSD symptoms. These reactions to ICU-related losses may be shaped by family members' personalities, expectations, and emotion regulation styles. Understanding these characteristics could inform family screening and intervention efforts in the ICU.
