A new scale, the Graduated Compression Stockings Compliance Scale (GCSAS), has been developed and validated. This tool objectively measures patient adherence to graduated compression stockings (GCSs) for chronic venous disease (CVD).
Area of Science:
- Vascular Medicine
- Medical Device Technology
- Patient Adherence Research
Background:
- Graduated compression stockings (GCSs) are standard treatment for chronic venous disease (CVD).
- Objective assessment of GCSs adherence is currently lacking.
- A validated tool is needed to accurately measure patient compliance.
Approach:
- Developed the Graduated Compression Stockings Compliance Scale (GCSAS) based on literature review and expert interviews.
- Conducted pilot tests and exploratory factor analysis to refine scale items.
- Evaluated the reliability and validity of the 17-item, 5-dimension GCSAS in 290 subjects.
Key Points:
- The GCSAS demonstrated strong internal consistency (Cronbach's alpha = 0.90) and reliability (test-retest = 0.81, split-half = 0.92).
- Construct validity was supported by significant positive correlation with quality of life scores (r = 0.76).
- Factor analysis confirmed a robust structure, explaining 79.13% of the variance.
Conclusions:
- The GCSAS is a valid and reliable instrument for assessing patient compliance with GCSs in CVD.
- This scale provides a standardized tool for future clinical research and practice.
- Improved adherence assessment can lead to better management of chronic venous disease.
