Objectives: to briefly outline the development and validation of the Parkinson's Disease Questionnaire (PDQ-39) and then to provide evidence for the use of the measure as either a profile of health status scores or a single index figure. Design: the PDQ-39 was administered in two surveys: a postal survey of patients registered with local branches of the Parkinson's Disease Society of Great Britain (n = 405) and a survey of patients attending neurology clinics for treatment for Parkinson's disease (n = 146). Data from the eight dimensions of the PDQ-39 were factor-analysed. This produced a single factor on the data from both surveys.

Apr 18, 2007  The 39 item Parkinson's disease questionnaire (PDQ‐39) is the most widely used patient reported rating scale in Parkinson's disease. However, several fundamental measurement assumptions necessary for confident use and interpretation of the eight PDQ‐39 scales have not been fully addressed. Nov 04, 2019  A short-form questionnaire, the PDQ-8, is composed of eight items, each of which represents one PDQ-39 dimension. The PDQ-39 is the most extensively tested and used HRQoL-specific instrument for PD. The 39-item Parkinson's disease Questionnaire (PDQ-39) was the first specific and a consistent instrument for the evaluation of HRQL in PD patients. Kenmore elite electric range manual. To test the reliability and validity of Chinese. Jan 29, 2014 The PDQ-39 is a 39-item self-report questionnaire, which assesses Parkinson’s disease-specific health related quality over the last month. Assesses how often patients experience difficulties across the 8 quality of life dimensions.

Outcome measures: the eight dimensions of the PDQ-39 and the new single index score—the Parkins's disease summary index (PDSI), together with clinical assessments (the Columbia rating scale and the Hoehn and Yahr staging score).

Results: in the postal survey 227 patients returned questionnaires (58.2%). All 146 patients approached in the clinic sample agreed to take part. Higher-order principal-components factor analysis was undertaken on the eight dimensions of the PDQ-39 and produced one factor on both datasets. Consequently it was decided that the scores of the eight domains could be summed to produce a single index figure. The psychometric properties of this index were explored using reliability tests and tests of construct validity. The newly derived single index was found to be both internally reliable and valid.

• The 39 item questionnaire offers a patient reported measure of health status and quality of life and is the most frequently used disease-specific health status measure. The Parkinson's Disease Questionnaire (PDQ-39) assesses how often people affected by Parkinson's experience difficulties across 8 dimensions of daily living including relationships, social situations and communication.
• The 39-item Parkinson's Disease Questionnaire, and particularly its summary index (PDQ-39SI) is a widely used patient-reported clinical trial endpoint. A basic assumption when summing items into a total score is that they represent a common variable.

Discussion: data from the PDQ-39 can be presented either in profile form or as a single index figure. The profile should be of value in studies aimed at determining the impact of treatment regimes upon particular aspects of functioning and well-being in patients with Parkinson's disease, while the PDSI will provide a summary score of the impact of the illness on functioning and well-being and will be of use in the evaluation of the overall effect of different treatments. Furthermore, the PDSI reduces the number of statistical comparisons and hence the role of chance when exploring data from the PDQ-39.
