What is Parkinson's Disease Questionnaire-39 (PDQ-39)
The Parkinson's Disease Questionnaire-39 (PDQ-39) stands as the leading tool for checking health-related quality of life in people living with Parkinson's. This self-report survey features 39 questions that look at how the condition impacts a person over the last month. It captures the patient's own view of their overall health status. It covers eight specific areas like mobility, activities of daily living, emotional well-being, and stigma. Patients answer on a five-point scale ranging from never to always, allowing clinicians to spot specific physical or social issues clearly. Taking about 10 to 15 minutes to finish, the PDQ-39 is easy to use in busy clinics or research trials. Doctors use the scores to see if treatments are working well. It is a practical way to measure the full impact of the disease beyond just motor symptoms and guide better care plans.
The PDQ-39 can be scored using two main approaches: calculating specific dimension scores and a single summary index. 1. Dimension Scores: Patients rate items from 0 to 4. For domains like Mobility or Stigma, you sum the points, divide by the maximum possible score, and multiply by 100. This creates a 0 to 100 scale where lower numbers mean better quality of life. 2. Summary Index: This method averages the eight dimension scores into one total figure. It is handy for tracking overall health changes in the clinic without getting lost in the details, giving a quick snapshot of how a patient is travelling.
