Analysis

The Parkinson’s Disease Questionnaire – PDQ-39 is used to assess the quality of life in individuals with Parkinson’s disease, measuring the impact of the disease on various aspects of daily life and well-being.

Objective

The main objective of the PDQ-39 is to evaluate the quality of life of individuals suffering from Parkinson’s disease, taking into account the different aspects of their functionality and well-being. The tool provides information about life areas affected by the condition, such as mobility, activities of daily living, social life, and psychological state.

Scoring

The PDQ-39 consists of 39 questions covering eight key domains of quality of life:
Mobility
Activities of Daily Living
Emotional Well-being
Stigma
Social Support
Cognitions
Communication
Bodily Discomfort
Responses within these domains are scored and combined to provide an overall picture of the individual’s quality of life.
