Popis: | The DSM-IV-TR postulates that PTSD symptoms are organized into 3 clusters. This assumption has been challenged by growing number of factor analytical studies, which tend to favor 4-factor, first-order models. Our objective was to investigate whether the clusters of PTSD symptoms identified in North American and European studies could be replicated in a Brazilian sample composed of 805 primary care patients living in hillside slums. Volunteers were asked to fill out the Brazilian version of the Posttraumatic Stress Disorder Checklist—Civilian Version and a confirmatory factor analysis of this scale was conducted with the software LISREL 8.80. Seven models were tested and a 4-factor, first-order solution including an emotional numbing cluster was found to provide the best fit. Although PTSD has been characterized by some critics as a Western culture-specific disorder lacking universal validity, our results seem to uphold the cross-cultural validity of the 4-factor, first-order model. |
