The research was conducted in a military unit of British Armed Forces in London. The outcomes of PCL-M questionnaire indicated PTSD in 56% of the subjects (N = 28). According to the analysis, the percentage of correct classification of the model taking into account the variables of trauma intensity (chi2(1) = 37.1; p < 0.01), prior traumatization (chi2(1) = 24.8; p < 0.01) and the size of the group of individuals to provide support (chi2(1) = 0.9) is estimated to be 90%. The variables with the greatest impact on the development of PTSD proved to be the intensity of the trauma and early traumatization. The size of the group of people who can provide support proved to contribute to the occurrence of PTSD in combination with the other two variables.plcombat stressmilitary missionPTSDtrauma intensityprior traumatizationsupport groupArtykuł
