title: The Aberfan disaster: 33-year follow-up of survivors.
abstract: BACKGROUND
  Experiencing life-threatening events often contributes to the onset of such psychiatric conditions as post-traumatic stress disorder (PTSD). Children can develop PTSD; however, there is controversy over whether PTSD symptoms decrease or persist over time.
  
  
  OBJECTIVE
  To examine the long-term effects of surviving the 1966 Aberfan disaster in childhood.
  
  
  METHODS
  Survivors (n=41) were compared with controls (n=72) matched for age and background. All were interviewed using the Composite International Diagnostic Interview, measures of current health and social satisfaction, and the General Health Questionnaire. The survivor group also completed the Impact of Event Scale to assess current levels of PTSD.
  
  
  RESULTS
  Nineteen (46%; 95% CI 31-61) survivors had had PTSD at some point since the disaster, compared with 12 (20%; 95% CI 10-30) controls (OR=3.38 (95% CI 1.40-8.47)). Of the survivors,12 (29%; 95% CI 15-43) met diagnostic criteria for current PTSD. Survivors were not at a significantly increased risk of anxiety, depression or substance misuse.
  
  
  CONCLUSIONS
  Trauma in childhood can lead to PTSD, and PTSD symptoms can persist for as long as 33 years into adult life. Rates of other psychopathological disorders are not necessarily raised after life-threatening childhood trauma.
