Abstract
The aim of this prospective follow-up study was to investigate the role of trauma-related factors in the development of acute and chronic Posttraumatic Stress Disorder (PTSD) among South African gold mineworkers involved in disabling and reportable earth-fall mine accidents. A consecutive sample of 200 mineworkers who were involved in earth-fall mine accidents was evaluated over a period of seven months. A history of previous trauma exposure was associated with both acute and chronic PTSD. Injury severity predicted acute PTSD but could not differentiate between subjects with acute PTSD that developed chronic PTSD and those whose symptoms went into remission. The intensity and severity of the precipitating earth-fall event were associated with acute and chronic PTSD. Being pinned down by rocks was the earth-fall-related event that predicted chronic PTSD most accurately. The intensity of the traumatic earth-fall event was found to be a more significant predictor for acute PTSD than previous exposure to trauma. Based on these results, recommendations were made to manage trauma in the mining sector.
