Hypothesis
The study aims to analyze the internal consistency and construct validity of the Walter Reed Visual Assessment Scale (WRVAS) for scoliosis.
Conclusion
The WRVAS is a valid instrument for assessing scoliosis patients' perception of their deformity, showing excellent internal consistency and significant correlation with the magnitude of the deformity.
Supporting Evidence
- The WRVAS showed excellent internal consistency with a Cronbach's alpha of 0.9.
- All items on the WRVAS correlated significantly with the Cobbmax.
- The correlation between the total WRVAS and total SRS-22 score was -0.54.
- The study included a diverse group of patients with idiopathic scoliosis.
Takeaway
The WRVAS helps patients describe how they feel about their scoliosis, and it works well to measure their perception of the deformity.
Methodology
A cross-sectional study was conducted with 70 patients who filled out the WRVAS and SRS-22 questionnaires, and their curve angles were measured via X-rays.
Potential Biases
Potential bias in self-reported measures and the subjective nature of the assessment.
Limitations
The study is limited to internal consistency and construct validity, lacking analysis of reliability and sensitivity to change.
Participant Demographics
70 patients (60 women, 10 men) with a mean age of 19.4 years (range 12–40).
