What is Parkinson's Disease Quality of Life Questionnaire (PDQ)

The Parkinson's Disease Quality of Life Questionnaire (PDQ) is the main tool for checking how this condition affects daily living and health status. It serves as a patient-reported outcome measure that looks at specific health issues. The standard PDQ-39 version covers thirty-nine items across eight distinct areas of health. These areas include mobility, emotional well-being, stigma, and bodily discomfort. Patients answer questions about how often they face difficulties using a simple scale from never to always, helping clinicians see the full picture of a patient's struggles. Completing the form is easy and takes roughly ten minutes. It works well for clinical trials and routine check-ups to track changes over time. By focusing on the patient's voice, doctors can adjust care plans effectively. This helps professionals understand the true disease burden for better support.

PDQ Scoring

The Parkinson's Disease Quality of Life Questionnaire is scored using a dimension based calculation method. First, score each item from 0 for never to 4 for always. Then, sum the item scores within each of the eight dimensions like mobility or emotional wellbeing. To get the final metric, divide this sum by the maximum possible score for that section and multiply by 100. This gives a result between 0 and 100 for each domain. Keep in mind that higher numbers mean more problems and a lower quality of life. This helps clinicians spot specific areas where a patient might be struggling.
