Spirit possession is often linked to traumatic experiences, but the evidence for this relationship is inconsistent and methodologically limited. The review examines current global mental health research on trauma exposure and possession phenomena, finding that while some studies suggest a connection, many lack rigorous assessment of trauma and possession, and cultural factors are frequently overlooked. The authors call for more culturally sensitive and methodologically sound research to clarify the nature of this relationship.
In the Eastern Democratic Republic of the Congo, pathological spirit possession is a common explanation for unexplainable mental and physical health problems, especially among people affected by war. Among 73 formerly possessed individuals, mostly women, the most frequent explanation was that a family member or neighbor sent the spirit out of jealousy or conflict. Lifetime spirit possession was linked to more severe PTSD symptoms, depression, shame, guilt, psychotic symptoms, and physical complaints. Possession in the prior four weeks was linked to PTSD, impaired functioning, and psychotic symptoms. The findings suggest pathological spirit possession serves as a broad cultural framework for distress, including but not limited to trauma-related disorders.
