Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome variables are fatigue severity and functional disability. The Checklist Individual Strength (CIS) subscale for fatigue indicates the level of experienced fatigue over the past 2-week period and consists of 8 items that have to be answered on a 7-point scale. The score can range between 8 to 56. The scale is reliable, has a good validity, and is sensitive to change. To measure the level of disability the Medical Outcomes Survey Short Form-36 (SF-36) is used. Physical and social disabilities are measured with the *physical functioning* and *social functioning* subscale of the SF-36. The scores range from 0 (maximum limitations) to 100 (no limitations). The SF-36 is often used in treatment studies of CFS patients, is reliable and has a good validity. | — |
Secondary
| Measure | Time frame |
|---|---|
| The secondary outcome measure is the level op psychological distress measured with the Symptom Checklist 90 (SCL-90). The SCL-90 consists of 90 items scored on a 5-point Likert scale. The total score ranges from 90 to 450. A high total score reflects high psychological distress. This scale is widely used and the reliability and discriminating validity are good. | — |
