Lebensqualität bei chronisch entzündlichen Darmerkrankungen (CED): die deutsche Version des Inflammatory Bowel Disease Questionnaire (IBDQ-D) zur krankheitsspezifischen Lebensqualitätsmessung - erste Anwendung und Vergleich mit anderen internationalen Fassungen

International data suggest that the IBDQ-D is a suitable instrument for HRQOL-assessment in CD and UC. For both disease a statistically significant negative correlation with disease activity was found. Tested psychometric properties do not suggest that a revision of the IBDQ-D is required. The IBDQ-D offers the HRQOL-assessment as an primary or secondary outcome in clinical trials in IBD in Germany.
