The “Parkinson’s Disease Questionnaire” (PDQ) is a tool used in clinical research and practice to assess the quality of life and the impact of Parkinson’s disease (PD) on individuals. It was developed specifically for patients with Parkinson’s disease to capture various aspects of their physical, emotional, and social functioning.
The PDQ covers multiple domains such as mobility, activities of daily living, emotional well-being, social support, and cognition. By addressing these areas, clinicians and researchers can gain a comprehensive understanding of how Parkinson’s disease affects an individual’s life beyond just the physical symptoms.
The questionnaire typically consists of a series of statements or questions that patients answer based on their experiences. Responses are then scored to provide a quantitative measure of the impact of Parkinson’s disease on the patient’s quality of life. This information can be valuable in guiding treatment decisions, evaluating interventions, and monitoring disease progression.
Several versions of the PDQ exist, each tailored to specific populations or research purposes. These versions may vary in length and content but generally aim to assess similar core aspects of Parkinson’s disease and its impact on individuals.
