This study aims to translate and validate the Gastrointestinal Dysfunction Scale for Parkinson's Disease (GIDS-PD) into Italian to enable the assessment of gastrointestinal symptoms in Italian-speaking patients with Parkinson's disease. The psychometric properties of the translated instrument will be evaluated through a multi-phase process involving translation/back-translation, pre-testing, and large-scale validation across multiple Italian centers
