Abstract
Background and purpose - This study aims to investigate the validity and reliability of the Turkish Version of the 39-item Parkinson Disease Questionnaire. Methods - A total of 100 patients with Parkinson's disease who were admitted to the outpatient neurology clinic in Koc University and Istanbul University were enrolled. 39-item Parkinson Disease Questionnaire, Parkinson Disease Quality of Life Questionnaire, Unified Parkinson's Disease Rating Scale, Hoehn-Yahr Scale, and Short Form Health Survey-36 were administered to all participants. 39-item Parkinson Disease Questionnaire was repeated 2 weeks later. Results - The internal consistency coefficient of the 39-item Parkinson Disease Questionnaire was 0.957. Test-retest correlation ranged between r = 0.693-0.979. Reliability of Turkish version of the 39-item Parkinson Disease Questionnaire was found to be very high with the exclusion of one item (30(th) item). The scale was found to be consistent over time and correlated positively with Hoehn-Yahr Scale, and negatively with Unified Parkinson's Disease Rating Scale, Parkinson Disease Quality of Life Questionnaire, and Short Form Health Survey-36. Conclusion - Turkish version of the 39-item Parkinson Disease Questionnaire, with the exclusion of the 30th item can be used reliably in assessing the quality of life of Parkinson's patients.
