Summary
The Chinese Rehabilitation Set of the International Classification of Functioning, Disability, and Health (ICF-RS) shows good reliability and validity for assessing cancer patient rehabilitation progress. Further research is recommended for widespread clinical use.
Area of Science:
- Rehabilitation Medicine
- Psychometrics
- Oncology
Background:
- No comprehensive scale exists for assessing Chinese cancer patient rehabilitation.
- The International Classification of Functioning, Disability, and Health's Rehabilitation Set (ICF-RS) offers a potential solution.
Purpose of the Study:
- Evaluate the psychometric properties of the Chinese ICF-RS for cancer patient rehabilitation.
- Determine its reliability and validity in this population.
Main Methods:
- Administered the Chinese ICF-RS to 1055 cancer patients.
- Assessed internal consistency (Cronbach's alpha), test-retest, and inter-rater reliability.
- Explored construct validity via factor analysis and criterion validity against HADS, ECOG, and MBI.
Main Results:
- ICF-RS demonstrated good internal consistency (Cronbach's alpha = 0.87) and high reliability (ICC > 0.75).
- Factor analysis supported construct validity, explaining significant variance.
- Criterion validity was supported by significant correlations with MBI and HADS, but less so with ECOG.
Conclusions:
- The Chinese ICF-RS is a reliable tool for assessing cancer patient functioning and disability.
- Preliminary evidence supports its clinical application, though further validation is suggested.
- The instrument shows good internal consistency and high reliability.
