Development of a Questionnaire to Measure the Perceived Injustice of People Who Have Experienced Violence in War and Conflict Areas: Perceived Injustice Questionnaire (PIQ).

The findings of this study support the construct validity and the reliability of the PIQ. For this reason, it can be seen as a useful addition to the psychological assessment in psychotherapeutic settings of survivors of war and violence. In conclusion, and based on the PIQ, we suggest the development of a new set of therapy modules with worksheets, focusing on the perception, dealing, and understanding of feeling of injustice as an addition to the existing trauma therapy manual for therapy in war and conflict areas.
