The aim of this cohort study was : (i) to validate the diagnostic criteria for post-traumatic stress disorder (PTSD) of the DSM-III-R ; and (ii) to examine the incidence rate of PTSD in a study population exposed to two different traumatic events, i.e. a fire in a hotel ball-room and a multiple collision car-crash on a Belgian highway.
One hundred and eighty-five victims (130 fire and 55 car accident victims) were assessed between 7 and 9 months after the traumatic event using the Composite International Diagnostic Interview (CIDI), PTSD Module, a fully structured diagnostic interview for the assessment of PTSD according to DSM-III-R criteria.
Twenty-three percent of the study population met DSM-III-R criteria for PTSD.
By means of unsupervised and supervised multivariate statistical analyses we were unable to validate the three-factorial structure, i.e. criteria B, C and D, of the DSM-III-R PTSD diagnosis.
The latter relies heavily on the C diagnostic criteria, which appear to be too restrictive.
Women were more likely to develop symptoms of reexperience (B) and arousal (D) than men.
There was a significantly higher incidence of criteria B, C and D, but not of PTSD, in fire than in car-accident victims.
Between 42 and 57% of the victims developed the first PTSD symptoms on the day of the trauma ; within the next week these incidence rates increased to 77.1,57.8 and 73.5% for criteria B, C and D, respectively. (...)
