Summary
The new visual analog scale version of the QuickDASH (Disabilities of the Arm, Shoulder and Hand Questionnaire) demonstrates reliable test-retest results. This validated tool offers a reliable alternative for assessing upper extremity disorders.
Area of Science:
- Orthopedics
- Rehabilitation Medicine
- Health Outcomes Measurement
Background:
- The QuickDASH (Disabilities of the Arm, Shoulder and Hand Questionnaire) uses an ordinal scale.
- A visual analog scale (VAS) version was developed to enhance sensitivity and compatibility with other measures.
- This study evaluated the reliability of the VAS QuickDASH in patients undergoing treatment.
Purpose of the Study:
- To assess the test-retest reliability of the QuickDASH VAS.
- To determine if the VAS version is a suitable alternative to the original QuickDASH.
- To evaluate its utility in patients with upper extremity disorders.
Main Methods:
- A test-retest reliability study design was employed.
- Thirty-eight patients with upper extremity disorders were evaluated.
- A two-day interval was used between assessments.
Main Results:
- The intraclass correlation coefficient (ICC) for the 11-item VAS QuickDASH was 0.90.
- The ICC for the 15-item VAS QuickDASH (including work component) was 0.94.
- These reliability measures were comparable to the original QuickDASH.
Conclusions:
- The QuickDASH VAS questionnaire exhibits acceptable test-retest reliability.
- It serves as a viable alternative to the original QuickDASH for patient evaluation.
- The VAS format enhances measurement sensitivity and compatibility.
