title: [Cross-cultural adaptation of the Brazilian version of the Impact of Events Scale-Revised (IES-R)].
abstract: The Impact of Events Scale-Revised (IES-R) is used to screen for post-traumatic stress disorder (PTSD). The aim of this study was to assess the cross-cultural adaptation of the IES-R. The scale was translated into Brazilian Portuguese and culturally adapted. Reliability and validity were evaluated in 45 individuals divided into three groups of 15 (without PTSD, with PTSD, and treated for PTSD). Reliability was evaluated using intraclass correlation coefficient - ICC and Cronbach's alfa. Discriminant validity was evaluated by comparing mean IES-R scores in the three groups. The area under the ROC curve (AUC) was evaluated to determine cut-offs with higher sensitivity (s) and specificity (e) using the clinical interview (DSM-IV) as reference. The IES-R showed good reliability (ICC = 1; alfa from 0.75 to 0.93). The mean IES-R scores (p < 0.05) and ROC curve had good discriminant validity for a cut-off of 5.6 (s = 0.80, e = 0.70 and AUC = 0.81). The Brazilian version of IES-R showed good properties and can be a useful screening tool for PTSD.
