Validation of a french adaptation of the harvard trauma questionnaire among torture survivors from sub-saharan african countries

Abstract

Background: To date no validated instrument in the French language exists to screen for posttraumatic stress disorder (PTSD) in survivors of torture and organized violence. Objective: The aim of this study is to adapt and validate the Harvard Trauma Questionnaire (HTQ) to this population. Method: The adapted version was administered to 52 French-speaking torture survivors, originally from sub- Saharan African countries, receiving psychological treatment in specialized treatment centers. A structured clinical interview for DSM was also conducted in order to assess if they met criteria for PTSD. Results: Cronbach's alpha coefficient for the HTQ Part 4 was adequate (0.95). Criterion validity was evaluated using receiver operating characteristic curve analysis that generated good classification accuracy for PTSD (0.83). At the original cut-off score of 2.5, the HTQ demonstrated high sensitivity and specificity (0.87 and 0.73, respectively). Conclusion: Results support the reliability and validity of the French version of the HTQ. © 2012 Capucine de Fouchier et al.
