Brief Summary

Purpose of the study is the validation of the German version of the Injustice Experience Questionnaire. Pretest: Participants were informed about the aims of the study and fill in a consent form. They filled in a paper version of the German translation of the Injustice Experience Questionnaire. In a structured interview patients were asked if there were any items difficult to understand, unacceptable or offending them. Subsequently they had to answer questions about the content and meaning of the IEQ-items. Validation Study: Participants were informed about the aims of the study and filled in a consent form. By e-mail they received an access link to the online survey. The questionnaires of the survey could be filled in at home. The survey could be interrupted and terminated later. About 20 minutes were needed to answer the 80 questions of the survey. All data was saved anonymously during the survey.
