Measuring Quality of Life in the Speaker with Dysarthria: Reliability and Validity of the European Portuguese Version of the QoL-DyS

Conclusion: The QoL-DyS correlated positively with the QAD, PEAT-10, and EQ5D. Cronbach ’s α was 0.973, and it remained excellent when any item was deleted. The QoL-DyS score mean difference between the non-dysarthric cohort and the dysarthric cohort was also significant. Confirmatory factor analysis did not validate the original 40-item scale but a 33-item scale maintaining the fou r domains of the original version. A significantly higher perception of QoL was found in the non-dysarthric group. The results indicate that the European Portuguese version of the QoL-DyS is a reliable and valid tool to assess QoL in patients with dysarthria and may be used for screening in clinical practice and in research.Folia Phoniatr Logop
