Fatigue (CIS)
The Checklist Individual Strength (CIS) is a 20-item fatigue questionnaire developed in Dutch 1). The questionnaire has been translated into multiple languages and is used in various illnesses, including chronic fatigue syndrome/myalgic encephalomyelitis (ME/CFS).
Note that (chronic) fatigue is also assessed in Lifelines using the CDC and the PROMIS questionnaires, and some general questions.
Scoring
De CIS consists of 20 statements on fatigue-related problems respondents might have experienced in the past 2 weeks. A Likert scoring scheme is used: with each statement respondents have to give a score between 1 and 7, indicating how much the statement applies to them.
A factor analysis indicated 4 components in the 20 questions:
- Subjective fatigue (8 items)
- Concentration (5 items)
- Motivation (4 items)
- Physical activity (3 items)
