The Parkinson's Disease Questionnaire (PDQ-39) is a 39-item self-administered questionnaire with eight subscales: mobility, activities of daily living (ADLs), emotional well-being, stigma, social support, cognitive impairment, communication, and physical discomfort (Gaudet, 2002). The questionnaire is scored on a scale from 0 to 100 with lower scores indicating a better perception of health status (Gaudet, 2002). The PDQ-39 can be used as a valid and reliable tool for measuring quality of life for individuals with Parkinson's Disease (Gaudet, 2002). Its inclusion in comprehensive assessment is especially important due to the tendency of treatment to focus on motor deficits and cardinal features rather than other clinical features including depression, cognitive impairment, and fall risk which can significantly impact quality of life (Gaudet, 2002).
