Abstract
- Objective: We aimed to convert the English version of the Evaluation of Ankylosing Spondylitis Quality of life (EASi-QoL) into a Chinese version, and to test the reliability and validity of the Chinese version of EASi-QoL. Methods: The EASi-QoL was translated into Chinese. A total of 127 patients with ankylosing spondylitis (AS) were evaluated using the Chinese version of EASi-QoL to test its validity and reliability. Internal and test–retest reliability was assessed. In addition, correlation and exploratory factor analyses evaluating the structural, convergent, and criterion-related validities of this measure were performed. Results: The total Cronbach's α coefficient of the Chinese version of EASi-QoL was 0.911. The Kaiser–Meyer–Olkin value of the scale in this study was 0.917, and the Bartlett's test value was 2403.499. The convergent validity of the related domains was analyzed using confirmatory factor analysis; and the average variance extracted values corresponding to the four dimensions were all > 0.5, and the composite reliability values were all > 0.7. Discriminative validity analysis showed that the correlation between the four domains of EASi-QoL and their related domains of the depression/anxiety screening scale and the Medical Outcomes study Short-Form 36 were moderate to high. Conclusion: The Chinese version of EASi-QoL has high reliability and validity, and can reflect the impact of AS on the quality of life. Key Points • The Chinese version of EASi-QoL can accurately measure the impact of AS on the quality of life from the perspective of a patient. It is applicable to the evaluation of AS patients in China • The Chinese version of EASi-QoL is a scale with good reliability and validity [ABSTRACT FROM AUTHOR]
