Summary
The Questionnaire Rising and Sitting Down (QR&S) reliably measures functional limitations in rising and sitting. This self-administered tool is valid for assessing perceived and actual difficulties in daily activities.
Area of Science:
- Rehabilitation Medicine
- Physical Therapy
- Health Measurement
Background:
- Assessing functional limitations in rising and sitting is crucial for patients with lower extremity disorders.
- Existing tools may not adequately capture the nuances of these specific functional challenges.
Purpose of the Study:
- To develop and validate the Questionnaire Rising and Sitting Down (QR&S).
- To create a self-administered instrument for measuring perceived and actual functional limitations.
Main Methods:
- Developed the QR&S based on literature review and operationalized limitations.
- Utilized Mokken scale analysis to test dimensionality and scalability (H).
- Assessed reliability (Rho, ICC) and validity (content, construct) in 345 outpatients.
Main Results:
- Mokken analysis confirmed 5 object dimensions (H = .53-.59) and 2 global dimensions (H = .50-.54).
- The QR&S demonstrated robust hierarchical scales measuring functional limitations reliably (Rho .77-.91; ICC .72-.90).
- The instrument showed good validity, covering 3 out of 4 aspects and passing construct validity tests for most scales.
Conclusions:
- The Questionnaire Rising and Sitting Down (QR&S) is a reliable and valid self-administered tool.
- It effectively measures perceived and actual functional limitations in rising and sitting movements.
- The QR&S provides hierarchical scales beneficial for clinical assessment and research.
