Summary
The Chinese Fibromyalgia Impact Questionnaire (CFIQR) is a reliable tool for assessing fibromyalgia patient quality of life in research and clinical settings.
Area of Science:
- Rheumatology
- Health Outcomes Research
- Psychometric Validation
Background:
- Fibromyalgia significantly impacts patient quality of life.
- The Fibromyalgia Impact Questionnaire (FIQR) is a key assessment tool.
- A validated Chinese version is needed for global research and clinical practice.
Purpose of the Study:
- Translate and adapt the English FIQR into Chinese (CFIQR).
- Evaluate the psychometric properties of the CFIQR.
- Establish its validity and reliability in Chinese-speaking fibromyalgia patients.
Main Methods:
- Translation and cross-cultural adaptation of the FIQR.
- Recruitment of 200 fibromyalgia patients across 6 centers.
- Administration of CFIQR, SF-36, and BDI, followed by reliability and validity analyses.
Main Results:
- Excellent internal consistency (Cronbach's alpha .88–.93) and strong test-retest reliability (ICC >0.75).
- Significant correlations between CFIQR, SF-36, and BDI supported criterion validity (P < .01).
- Confirmatory factor analysis confirmed acceptable structural validity for the 3-factor model.
Conclusions:
- The Chinese version of the FIQR (CFIQR) is a valid and reliable instrument.
- CFIQR is suitable for both clinical practice and research involving Chinese speakers.
- This validated tool enhances fibromyalgia assessment globally.
