| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Questionnaire |
| Brief Description |
RA stiffness PRO measure (RAST) has 21 items and 3 components identifying stiffness severity, physical effect, and psychosocial effect. |
| Number of Items | 21 |
| Range | --- |
| Responses options/scale |
Yes There are 21 items and 3 components; two of the components use a 0-3 (not at all to very much) scale. The first component has 8 items with various response options scales. |
| Developed for | Clinical practice, Research |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered |
| Recommendations to score |
The RAST can be scored as individual components or as a total scale. To score, convert each item score to a % score using some tables. To generate a % score for individual components, add the % scores together and divide by the number of items within the component. To generate a % score for the total scale add together each % score for each individual component and divide by three. |

| Completion time by the patient | 10 minutes |
| Scoring time by the assessor | 0 minutes |
| Training to score | Not necessary |
| Strengths | Useful in clinical practice & research |
| Limitations | Complex scoring |
