Much research has established the negative effects of trauma; however, there is a growing body of empirical studies that have assessed positive growth from traumThis study examined use of the Posttraumatic Growth Inventory (PTGI) in a sample of humanitarian aid workers, a population often exposed to severe traumNational staff of six different countries served by a humanitarian aid organization completed questionnaires. Aid workers reported high levels of trauma exposure and posttraumatic stress (PTS) symptoms and rates of posttraumatic growth similar to other trauma populations. There were difficulties (related to the instruction set in utilizing the measures) in an international sample, though psychometrically, the PTGI showed good internal consistency across geographical regions. PTG and PTS severity were found to be positively related, though not in a subsample of individuals who reported threat to life or physical well-being. An initial hypothesis about time since trauma could not be completed due to too few participants completing required measures. Results of reliability analysis suggest support for the use of the PTGI in the Middle East, European Caucusus, and Balkans, and the usefulness of the measure for understanding the experience of national humanitarian staff that are exposed to traum[Author Abstract]
