Objective:
To evaluate the validity, reliability, and cultural relevance of the Arthritis Impact Measurement Scales 2 (AIMS2) as a health assessment tool for Chinese-speaking patients with arthritis.
Methods:
The cultural relevance, language equivalency, and content validity of the AIMS2, Chinese version (CAIMS2) were evaluated by an expert panel. Measurement performance was tested on 240 subjects (rheumatoid arthritis = 81, osteoarthritis = 77, healthy = 82). Subjects (n = 175) were retested within 2 weeks for testing of reliability.
Results:
Three items were modified and 2 items were added, as suggested by the expert panel. Interitem reliability was satisfactory (intraclass correlation coefficient 0.8552-0.9594). Test-retest reliability of the CAIMS2 subscales ranged from 0.770 to 0.952 in subjects in whom the CAIMS2 was self administered. Significant score differences between patients with arthritis and healthy subjects were found in all 12 subscales, except for the support from family and friends and tension subscales. CAIMS2 subscale scores correlated with clinical and laboratory measures of disease activity and patients' perceived quality of life as measured using the Chinese version of the World Health Organization Quality of Life instrument.
Conclusion:
Empirical data support CAIMS2 is a valid and reliable health status measure for Chinese speaking patients with arthritis.
