Ringkasan	The PDQ-39 is the most widely used patient-reported outcome measure for Parkinson's disease quality of life. Developed by Crispin Jenkinson and colleagues in 1997, this 39-item self-report questionnaire comprehensively assesses how Parkinson's symptoms affect daily functioning, emotional well-being, stigma, social support, and cognitive-communication abilities. It is the recommended instrument in major Parkinson's disease clinical trials and forms a core component of outcome measurement in movement disorders.	The EORTC QLQ-C30 is the most widely used international instrument for assessing quality of life in cancer patients. Developed by the European Organisation for Research and Treatment of Cancer in 1993, it measures physical, emotional, cognitive, and social functioning alongside cancer-specific symptoms and financial impact, making it the standard outcome measure in oncology clinical trials and patient care.
