| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Composite Index, Questionnaire, Scale |
| Brief Description |
The ICOAP-Hip is a multidimensional osteoarthritis -specific measure designed to evaluate the pain experience in people with hip OA, including pain intensity, frequency, and impact on mood, sleep, and quality of life, independent of the effect of pain on physical function. It includes evaluation of two distinct types of pain: "constant pain" and "pain that comes and goes" that were identified by people with OA as important. |
| Number of Items | 11 grouped in 2 subscales: constant pain (5 items) and intermittent pain (6 items) |
| Range | 0-100 (normalized score) |
| Responses options/scale |
Yes ” and “very often” |
| Developed for | Clinical practice, Research |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered |
| Recommendations to score |
Each item is scored from 0–4. A score is separately calculated for each subscale by summing the items’ subscale scores and then normalizing each score from 0 (no pain) to 100 (extreme pain). A total ICOAP score can be calculated by summing the 2 subscale scores, and normalizing from 0 (no pain) to 100 (extreme pain). |
| Score Interpretation | Higher scores indicate a worse pain experience. |

| Training to score | Not necessary |
| Strengths | Useful in clinical practice & research |
