Validation of the Polish version of the Unified Dyskinesia Rating Scale (UDysRS).
Abstract
<h4>Background</h4>In 2008, the Movement Disorders Society published the Unified Dyskinesia
Rating Scale (UDysRS). This has become the established tool for assessing the severity
and disability associated with dyskinesia in patients with Parkinson's Disease (PD).
We translated and validated the Polish version of the UDysRS, explored its dimensionality,
and compared it to the Spanish version, which is the Reference Standard for UDysRS
translations.<h4>Material and methods</h4>The UDysRS was translated into Polish by
a team led by JS and GO. The back-translation, completed by colleagues fluent in both
Polish and English who were not involved in the original translation, was reviewed
and approved by the Executive Committee of the MDS Rating Scales Programme. Then the
translated version of the UDysRS underwent cognitive pretesting, and the translation
was modified based on the results. The approved version was considered to be the Official
Working Document of the Polish UDysRS and was tested on 250 Polish PD patients recruited
at movement disorder centres. Data was compared to the Reference Standard used for
validating UDysRS translations.<h4>Results</h4>The overall factor structure of the
Polish version was consistent with that of the Reference Standard version, as evidenced
by the high Confirmatory Fit Index score (CFI = 0.98). The Polish UDysRS was thus
confirmed to share a common factor structure with the Reference Standard.<h4>Conclusions</h4>The
Official Polish UDysRS translation is recommended for use in clinical and research
settings. Worldwide use of uniform rating measures offers a common ground to study
similarities and differences in disease manifestations and progression across cultures.
