Eligibility
Inclusion criteria
Inclusion criteria: 1. Persistent or relapsing unexplained chronic fatigue lasting 6 or more consecutive months (Fukuda et al, 1994); 2. Age between 18-65 years.
Exclusion criteria
Exclusion criteria: 1. In treatment with (pre)clinical hospitalisation for complaints of chronic fatigue during participation in the trial; 2. Wheelchair bounded patients; 3.

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary outcome measure is the physical activity level measured with an accelerometer. Firstly, it will be investigated if the average physical activity pattern through the day during the distribution of feedback will come closer to the stipulated norm. Secondly, it will be investigated if the distribution of feedback tips will lead to a changed physical activity level directly after the distributed feedback tip. | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary parameters are: 1. On the PDA the physical activity level will be scored subjectively on a visual analog scale from 0 till 10, and the questions about the experience and expectation with the feedback tips will be answered with 'yes' or 'no'; 2. The behavioral intention/motivation to follow the given feedback in order to get more balance in the physical activity pattern and determinants which are of influence on the behavioral intention/motivation will be evaluated by means of self drafted questionnaire with items scored on a 7 point scale; 3. The physical activity level will be measured subjectively by means of the Baecke questionnaire; 4. The users satisfaction and usability will be measured with an existing questionnaire containing 9 items scored on a 5 point scale; 5. The extent of fatigue will be measured with the CIS20 questionnaire; 6. Demographical data will be obtained towards age, gender, work status, length of complaints, diagnose of CFS and level of education. | — |
