A summary of PDS lifetime scores (mean, with range in the parentheses) and lifetime PTSD risk (percentage) according to DSM-IV criteria in survivors of the rebel war in Northern Uganda (African sample 1) and survivors of the 1994 Rwandan genocide (African sample 2). Please note that the calculation of traumatic event types was based on a checklist of 62 items in the African sample 1 and on a checklist of 36 items in the African sample 2.
