| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Questionnaire |
| Brief Description |
The AS-WIS is a simple, self-administered, 20-item scale which meets the stringent requirements of modern measurement. Used as a screening tool it can identify those experiencing a mismatch at work who are at risk of job retention problems and work disability. |
| Number of Items | 20 |
| Range | 0-20 |
| Responses options/scale |
Yes Dichotomous (yes/no) |
| Developed for | Both |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered |
| Recommendations to score |
Scores are summed up. |
| Score Interpretation | Higher scores indicated higher risk of work disability. |

| Smallest detectable change if described | --- |
| Smallest detectable change applied to | Not specified |
| Completion time by the patient | - minutes |
| Scoring time by the assessor | - minutes |
| Training to score | Not necessary |
| Strengths | Easy to use, Useful in clinical practice & research |
