| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Scale |
| Brief Description |
JSS consists of four items that evaluate sleep problems over the preceding four weeks. Each item is rated on a six-point Likert scale. This questionnaire asked how many times during the last month the subject had experienced the following; “trouble falling asleep,” “trouble staying asleep (i.e. wake up far too soon and can’t get back to sleep)“, “waking up several times per night,” and “waking up after your usual amount of sleep feeling tired and worn out.” |
| Number of Items | 4 |
| Range | 0-20 |
| Responses options/scale |
Yes 0-5 |
| Developed for | --- |
| PRACTICAL APPLICATION | |
| Method of administration | Self-administered |
| Recommendations to score |
The following six response categories were available for each question: Not at all, 1-3 days, 4-7 days, 8-14 days, 15-21 days, and 22-31 days. Responses were then coded on a O-5 scale (not at all = 0). All items were equally weighted and summed. |
| Score Interpretation | Higher scores indicate higher sleep problems. |

| 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 |

| OTHER COMMENTS | |
| Other Comments |
The original scale's did not introduce substantial bias in capturing the experience of fibromyalgia-related sleep disturbances. Furthermore, JSS-TR is a valid, simple and feasible sleep instrument that can be easily applied to FMS patients both in researches and clinical settings. It is also a valid and reliable instrument in PsA. |
