Key result
Chinese 8-item and 5-item AF Information Overload Scales demonstrate good psychometric properties and high reliability.
Why the study?
Patients with AF experience information overload, and while the Atrial Fibrillation Information Overload Scale (AFIOS) has been validated in Australia, a validated Chinese version was not available.
Cross-Sectional (n=362)
The Chinese versions of the 8-item and 5-item Atrial Fibrillation Information Overload Scale are valid and reliable tools for assessing information overload in AF patients.
Chinese AFIOS enables overload assessment in Chinese AF patients; extends validation beyond Australian cohorts but leaves clinical adoption open pending further testing.
PURPOSE: Patients with atrial fibrillation (AF) experience information overload during self-management and engagement in health care. The Atrial Fibrillation Information Overload Scale (AFIOS) has been validated and used to assess information overload in Australian AF population. However, a validated Chinese version of AFIOS is not available. The aim of this study was to translate the 8-item and modified 5-item AFIOSs from English into Chinese and test their psychometric properties. METHODS: Translation and cross-cultural adaption were conducted according to international guidelines. The translated scales were administered to 362 patients with AF from May 2022 to March 2023. Psychometric evaluation included item analysis, content validity, construct validity, and reliability. RESULTS: All items had item-total correlation coefficient over .30 and were significantly different between high-scoring and low-scoring groups. Exploratory factor analysis revealed that both versions were one-factor structure, explaining 52.1% and 52.7% of the total variance. Confirmatory factor analysis indicated that the one-factor model fit the data well in both versions. The scale level-content validity index, Cronbach α, and test-retest reliability of the 8-item scale were .96, .87, and .97, respectively; those of the 5-item scale were .97, .75, and .95, respectively. CONCLUSION: Chinese versions of both the scales exhibit good psychometric properties. Healthcare professionals could utilize the 5-item version scale to assess AF patients' information overload and develop targeted strategies to mitigate its negative impact on self-management and engagement.

Wu et al. (2025) conducted a cross-sectional in Atrial fibrillation (n=362). Chinese version of Atrial Fibrillation Information Overload Scale was evaluated on Psychometric properties including item analysis, content validity, construct validity, and reliability. The Chinese versions of the 8-item and 5-item Atrial Fibrillation Information Overload Scale demonstrated good psychometric properties, with the 8-item scale showing a Cronbach α of 0.87.
