Planning needs and services after collective trauma: should we look for the symptoms of PTSD?
CarmeloVazquez & Pau Perez-Salesi, 2007
The incidence of PTSD After the Madrid March 11, 2004 terrorist attacks, ranged from what can be expected as a normal prevalence in general population in Spain under non-traumatic conditions to values that, when applied to the general population, could be considered a dramatic epidemic of PTSD. These results demonstrate that inferences about the impact of traumatic events on the general population largely depend on the measure, definition and criteria used by the researcher. Slightly changing the criteria for PTSD makes an enormous difference to the amount of traumatization that is found (Intervention 2007, Volume 5, Number 1).
