The level of agreement between the numerical rating scale and visual analogue scale for assessing pain intensity in adults with chronic pain
Authors' conclusion
This study failed to show an acceptable agreement between the numerical rating scale and visual analogue scale when pain intensity was rated by adults with chronic pain, despite showing both scales measure the same information.
Study context
- Population
- Adults with chronic pain
- Participants
- 366 adults
- Comparison
- NRS vs VAS for pain intensity
- Primary endpoint
- One-dimensionality and agreement between NRS and VAS scores (current, average, minimal and maximal pain)
Methodological detailsprospective, multicentre
- Prospective
- Multicentre
Primary result
As reported in the abstract
Agreement between NRS and VAS
Intra-class correlation coefficient range
0.739 to 0.858
Further findings
Proportion scoring minimal pain ≤ maximal pain
Agreement between pain severity categories
- 'moderate' for average and minimal pain; 'substantial' for current and maximal pain
