Almost 20 years ago, researchers in the Health Services Research Unit developed the 39-item Parkinson’s Disease Questionnaire (PDQ-39) in order to assess the impact of Parkinson’s disease on health-related quality of life. We are now conducting a series of interviews to explore and assess the current relevance of the questions in the original PDQ-39. This will help us to determine which questions, if any, may benefit from adjustment.
