This descriptive observational study will involve dyads of Parkinson Disease patients and their caregivers. Participants will be recruited from the Parkinson's Disease and Movement Disorders Centre of ASST Gaetano Pini-CTO. Validated questionnaires, such as the WHOQOL-Bref, the Self-care of Chronic Illness Inventory version 2, and the Caregiver Self-efficacy in Contributing to Self-care Scale, will be administered. The study will also include semi-structured interviews to gather qualitative data on the patients' and caregivers' perceptions of self-care. A non-probabilistic convenience sampling method will be used, with the inclusion of both patients at any disease stage and their primary caregivers. The sample size will range 311 dyads with 5% margin of error.

The primary objective of this study is to describe the proportion of self-care maintenance in the population with Parkinson's Disease and their respective caregivers. Gaining an in-depth understanding of the phenomenon in its experiential and perceptual components, as well as the meanings attributed to it, is essential for developing and validating a new tool capable of assessing and measuring self-care in Parkinson's Disease. The secondary objectives are (a) to describe the proportions of self-care monitoring and management in the population with Parkinson's Disease and their respective caregivers; (b) to explore the meaning attributed by patients with Parkinson's Disease to self-care in its three dimensions: self-care maintenance, monitoring, and management; (c) to describe the attitudes and self-care behaviours adopted by patients with Parkinson's Disease across different disease stages; (d) to explore the meaning attributed by caregivers of patients with Parkinson's Disease to self-care in its three dimensions: self-care maintenance, monitoring, and management; (e) to describe the attitudes and self-care behaviours adopted by caregivers of patients with Parkinson's Disease across different disease stages; (f) to identify the dimensions of self-care and the constructs that should be represented within the items of the new instrument, the Parkinson's Disease Self-care Questionnaire (PDSC-Q).
