Hypothesis
The study aims to validate the Persian version of the PDQ-39 questionnaire for assessing quality of life in Parkinson's disease patients.
Conclusion
The Persian version of PDQ-39 is a valid and reliable measure of quality of life in patients with Parkinson's disease.
Supporting Evidence
- The internal consistency reliability of the PDQ-39 was high with a Cronbach’s alpha of 0.93.
- Significant correlations were found between PDQ-39 scores and disease severity.
- Patients with longer disease duration had worse quality of life scores.
Takeaway
This study shows that a questionnaire can help understand how Parkinson's disease affects people's lives, and the Persian version works well.
Methodology
Two hundred Parkinson’s disease patients completed the Persian PDQ-39 questionnaire, and its reliability and validity were assessed using Cronbach’s alpha and intraclass correlation coefficients.
Limitations
