| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Composite Index, Questionnaire, Scale |
| Brief Description |
OSS is a self-assessment questionnaire of pain and function of the shoulder and measures outcomes after shoulder operations other than stabilization. The original version was published in 1996, and a revision published in 2009 (Dawson, 2009) clarified specifications for its use but only altered the method of scoring each item, not the content. The OSS contains the following two domains: pain and daily functions. It is possible to use subscales. |
| Number of Items | 12 |
| Range | 12-60 (original score); 0-48 (updated version) |
| Responses options/scale |
Yes the item scoring is 0 (worst) to 4 (best). |
| Developed for | Research |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered |
| Recommendations to score |
In the original OSS, the total score is the sum of the (completed) 12 items (scoring 1-5); 12 = best and 60 = worst. In the revised version, the total score is also the sum of the 12 items (scoring 0-4), but the scores are reversed, with score ranges from 0 = worst to 48 = best. The original scoring system (2006) changed in 2009: Each question on the OSS should be scored 0 to 4, with 4 representing the best (this is the opposite direction from the original method of scoring). The overall score is reached by simply summing the scores os the 12 items received for individual questions. When the 12 items are summed, this produces overall scores that run from 0 to 48 with 48 being the best outcome (to convert the “old system” of 60–12 to the 0–48 scoring system and vice versa simply subtract the score from 60). |
| Score Interpretation | Original version: 12 (no disability) to 60 (maximal disability). Revised OSS: 0 (maximal disability) to 48 (no disability). |

| Other Comments |
The OSS is widely used in clinical trials investigating both nonoperative and surgical interventions for people with shoulder conditions. E.g.:Carr, A. et al. Effectiveness of open and arthroscopic rotator cuff repair (UKUFF): a randomised controlled trial. Bone Joint J 2017;99-B:107–15 |
