Translation and cross-cultural adaptation of the 39-item Parkinson’s Disease Questionnaire (PDQ-39) to the Italian culture was performed by Oxford University Innovation in 2008, but this version has never been validated. Therefore, we performed the process of validation of the Italian version of the PDQ-39 (PDQ-39-IT) following the “Consensus-Based Standards for the Selection of Health Status Measurement Instruments” checklist. The translated PDQ-39-IT was tested with 104 patients diagnosed with Parkinson’s disease (PD) who were recruited between June and October 2017.

Introduction
. The clinical, social, and economic implications of Parkinson’s disease (PD) are significant; disability occurs leading to a low quality of life (QoL). Information on the QoL of patients with PD and studies on the relationship between QoL and motor and cognitive function are necessary for both research and clinical use to make informed decisions in healthcare and rehabilitation. The aim of this study was to determine which scales are most used to assess QoL in patients with PD.
