Reliability and validity analysis of the Chinese version of Evaluation of Ankylosing Spondylitis Quality of Life (EASi-QoL).
Article in Clinical rheumatology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveWe 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.
methodsThe 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.
resultsThe 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.
conclusionThe 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.
