Cross-cultural adaptation and measurment properties
Conclusion
The Brief IPQ-DLV is well understood by patients, health care professionals and first-grade students. It is easy to use, and takes less than 5 min to complete and score. The face and content properties were found to be acceptable. The reproducibility showed moderate to good reliability and a SDC of 1 point for group evaluation measurement and 3-4 points for individual evaluation measurement. The concurrent validity could only be assessed in a limited amount indicating that this needs to be further investigated. Unfortunately a gold standard for comparison representing similar (theoretical) constructs is not readily available. Responsiveness and interpretation of the items by different patient groups have not been investigated yet (Appendix B).
