Questionnaire-Description

The PDQLQ-37 consists of 37 questions covering four main domains of life affected by Parkinson’s disease:

Motor Function: Assesses movement problems, such as tremors, stiffness, and difficulty in motion.

Emotional State: Evaluates the impact of the disease on mental health, including depression, anxiety, and mood changes.

Social Function: Measures the effect of the disease on social activities and the ability to participate in daily social interactions.

Parkinson’s Disease Quality of Life Questionnaire [PDQLQ-37]

Description and Objective

The Parkinson’s Disease Quality of Life Questionnaire (PDQLQ-37) is a disease-specific instrument designed to assess the impact of Parkinson’s disease on patients’ quality of life. It provides a multidimensional assessment of the physical, psychological, social, and everyday consequences of the condition.

Structure and Scoring

The PDQLQ-37 consists of 37 items covering four major domains: motor function, emotional state, social function, and daily activities. Responses are recorded using a Likert-type scale, allowing the degree of impact of Parkinson’s disease on different areas of life to be quantified.

Reliability and Applications

The psychometric evaluation of the PDQLQ-37 may include internal consistency analysis, factor analysis, and cross-validation. The questionnaire can be used in clinical practice and research to identify the areas of life most affected by Parkinson’s disease, monitor patients over time, and evaluate changes following therapeutic interventions.
