AIMS: The German Version of the Involvement Evaluation Questionnaire (IEQ-EU), developed for the assessment of burden on relatives of mentally ill people will be presented. Also the results of the reliability analysis will be presented. METHOD: After translation and adaptation of the Dutch version of the IEQ-EU into German, the instrument was tested in the study "Cost-effectiveness of psychiatric service systems". RESULTS: The internal consistency was tested on a sub-sample of 138 relatives and the Test-Retest-Reliability on a sub-sample of 37 relatives. The internal consistency (Cronbachs alpha) is moderate or good and slightly lower in comparison with the other European versions. With the exception of one subscale the results for the intraclass correlation coefficient are equal to the European versions. CONCLUSIONS: The IEQ-EU is an instrument with moderate or good psychometric properties. It covers all important domains, is easy to understand and not time-consuming.
