RESUMO
Our objective was to identify variables related to the onset of acute posttraumatic stress disorder (PTSD) after a road traffic accident. We evaluated 60 victims of a motor vehicle accident (MVA) in 2004 at 2 months postaccident. Thirty of them had developed PTSD; the other 30 had not developed PTSD. Clinical data, physical injuries, and sociodemographic characteristics were determined in 60 victims. The Davidson Trauma Scale (DTS) and a Structured Clinical Interview for DSM-IV (SCID) were used to evaluate PTSD occurrence. PTSD scores assessed by DTS and SCID at 2 months were significantly and positively associated with female sex, severe physical injuries, perceived social deprivation, and loss of job activity due to the accident. Female sex, severe physical injury, perceived social deprivation, and sick leave were related to the diagnosis of PTSD 2 months after the accident.
