“…Patients did not encounter any particular difficulties in understanding the items of the AFKS-C. None of the items had to be modified to fit the Chinese cultural context, except for the item related to the function of the thrombosis center, which was modified to "warfarin clinic" to fit the terminology used in Hong Kong. In terms of reliability, in this study, we recorded a Kuder-Richardson formula 20 value of 0.60 for the AFKS-C, which indicated only borderline internal consistency. Other AF knowledge tests, such as the Knowledge about AF and Self-Management survey, 36 the Knowledge of AF test, 37 and the Knowledge of Atrial Fibrillation and Stroke Prevention Questionnaire, 38 have reported Cronbach α values greater than 0.80. Such differences in the internal consistency values between these tests and the AFKS-C could be due to the number of items in these tests.…”

Background: Assessment of patients' knowledge on atrial fibrillation (AF) and its management is important for evaluating their learning needs. However, a validated and comprehensive instrument to be used among Chinese patients is yet to be developed. Objectives: The aim of this study was to develop and validate the Chinese version of the Atrial Fibrillation Knowledge Scale (AFKS-C) in Chinese patients. Methods: The 11-item AFKS was translated, and then content and face validations were conducted by an expert panel and patients with AF. A sample of 255 patients with AF was recruited from a university-affiliated hospital to evaluate its psychometric properties. The internal consistency and test-retest reliability were evaluated using the Kuder-Richardson formula 20 and κ statistics. Item analysis determined the item difficulty index and item discrimination coefficients. Factorial and discriminant validity were evaluated using exploratory factor analysis and the known-groups method. Results: The content validity index of the AFKS-C was 0.94, and the Kuder-Richardson formula 20 value was 0.60. The difficulty indices of the items ranged from 0.36 to 0.89, and the point-biserial coefficients of the items ranged from 0.122 to 0.255, indicating sufficient discriminatory ability. The test-retest reliability was acceptable, because the κ values ranged from 0.234 to 0.710. The principal axis factoring analysis indicated a 3-factor structure that explained 50.4% of the total variance. The AFKS-C also demonstrated satisfactory discriminant validity, having yielded significantly different scores between patients with newly diagnosed and established AF. Conclusion: The AFKS-C has acceptable psychometric properties and can be used to measure the knowledge of patients and evaluate the effects of patient education programs.

“…16 However, the authors also did not perform adequate psychometric testing other than content and face validity. Recently, McCabe et al published the newly developed self-management instrument in patients with AF; 40 it has shown adequate content and construct validity as well as internal consistency reliability. Thus, we recommend confirming convergent validity using AF-SCS-10 and this newly developed instrument in future studies.…”

Background Patients with atrial fibrillation (AF) require continuous self-care due to possible complications and side effects from treatment. However, existing tools do not capture all of the critical factors of AF self-care and have limited evidence of reliability and validity. Aims The aim of this study was to develop and evaluate a new Atrial Fibrillation Self-Care Scale-10 (AF-SCS-10) that assesses disease-specific, multidimensional, person-centered self-care for AF patients in South Korea. Methods For this cross-sectional research design, 290 individuals over 20 years of age with a diagnosis of AF for at least three months were recruited. A literature review and in-depth interviews were utilized to identify the scale items. An expert panel evaluated the validity and reliability of a preliminary scale. Exploratory factor analysis and parallel analysis was performed to extract factors; confirmatory factor analysis (CFA) was performed to evaluate fit on the factor structures. Criterion validity was supported by the correlation between AF-SCS-10 and AF quality of life. Results The internal consistency reliability coefficient was 0.87. Three factors, “self-care knowledge,” “self-care behavior,” and “self-care resources” were extracted from the exploratory factory analysis, explaining 79.30% of the total variance in the data. The three-factor model was also confirmed by parallel analysis; CFA met the fitness criteria. Conclusion There is preliminary evidence for internal consistency reliability, as well as content and construct validity, for the AF-SCS-10. Future research is needed to confirm the study results using a larger, more culturally diverse sample.

“…Knowledge scores are calculated as a percentage of correct answers, with higher numbers indicating higher knowledge. Four items were removed from the overall knowledge percent scores, as per McCabe et al [ 25 ] finding that these items had factor loadings below .45 and were not reliable predictors of overall test performance and knowledge. The Knowledge about AF tool demonstrated an internal consistency reliability coefficient of .86, convergent validity (i.e., was positively related to another knowledge about AF test), and distinguished between patients recently diagnosed with AF from those seeking advanced treatment for AF [ 25 ].…”

Background Patients with atrial fibrillation (AF) have significantly lower health-related quality of life (HRQoL) compared to the general population and patients with other heart diseases. The research emphasis on the influence of AF symptoms on HRQoL overshadows the role of individual characteristics. To address this gap, this study’s purpose was to test an incremental predictive model for AF-related HRQoL following an adapted HRQoL conceptual model that incorporates both symptoms and individual characteristics. Methods Patients attending an AF specialty clinic were invited to complete an online survey. Hierarchical regression analyses were conducted to examine whether individual characteristics (overall mental health, perceived stress, sex, age, AF knowledge, household and recreational physical activity) incremented prediction of HRQoL and AF treatment satisfaction beyond AF symptom recency and overall health. Results Of 196 participants (mean age 65.3 years), 63% were male and 90% were Caucasian. Most reported ‘excellent’ or ‘good’ overall and mental health, had high overall AF knowledge scores, had low perceived stress scores, and had high household and recreation physical activity. The mean overall AF Effect On Quality-Of-Life Questionnaire (AFEQT) and AF treatment satisfaction scores were 70.62 and 73.84, respectively. Recency of AF symptoms and overall health accounted for 29.6% of the variance in overall HRQoL and 20.2% of the variance in AF treatment satisfaction. Individual characteristics explained an additional 13.6% of the variance in overall HRQoL and 7.6% of the variance in AF treatment satisfaction. Perceived stress and household physical activity were the largest contributors to overall HRQoL, whereas age and AF knowledge made significant contributions to AF treatment satisfaction. Conclusions Along with AF symptoms and overall health, individual characteristics are important predictors of HRQoL and AF treatment satisfaction in AF patients. In particular, perceived stress and household physical activity could further be targeted as potential areas to improve HRQoL.
