BACKGROUND: The Atrial Fibrillation Effect on Quality-of-Life Questionnaire (AFEQT) is a psychometrically sound instrument for measuring disease-specific health-related quality of life in atrial fibrillation populations.

OBJECTIVE: In this study we aimed to validate the Chinese version of AFEQT (AFEQT-C) among Chinese patients with atrial fibrillation.

METHODS: The AFEQT was translated into Chinese according to Brislin's model. The psychometric properties of internal consistency, stability, and concurrent and factorial validity were examined in a convenience sample.

RESULTS: A total of 200 participants (mean age, 69.8 ± 5.2 years) were recruited. The Cronbach's α of the AFEQT-C was 0.94, and item-to-total correlations ranged from 0.44 to 0.80. The test-retest reliability was supported by good to excellent intraclass correlation coefficients, which ranged from 0.68 to 0.92. The AFEQT-C scores significantly correlated with the EuroQoL 5-Dimensional Questionnaire score to support concurrent validity. Confirmatory factor analysis demonstrated a 3-factor structure and all items loaded strongly onto their respective factors.

CONCLUSIONS: The AFEQT-C is a reliable and valid measure of health-related quality of life in Chinese patients with atrial fibrillation.
