Vietnamese version of the coronary artery disease education questionnaire-Short version: Translation, adaptation and validation

Cultural Adaptation and Psychometric Validation of a Cardiac Knowledge Questionnaire for Chinese Immigrants

BACKGROUND

Disease-related knowledge deficits are common in Chinese immigrants living in Western countries, putting them at risk of disease progression and mortality, particularly those with a coronary heart disease (CHD) diagnosis. However, no measurement instrument is available to assess CHD-related knowledge in this population.

OBJECTIVES

The aim of this study was to culturally adapt and examine the psychometric properties of the short version of Coronary Artery Disease Education Questionnaire (CADE-Q SV) (simplified Chinese version) in Chinese immigrants with CHD.

METHODS

Mandarin-speaking people recruited from medical centers and cardiology clinics across metropolitan Sydney completed the 20-item CADE-Q SV (5 domains; potential scores: 0-20). Internal consistency was assessed using Cronbach α . A subgroup (n = 40) repeated the survey 2 weeks later for test-retest reliability by intraclass correlation coefficient. Factor structure (confirmatory factor analysis) and discriminant (known-groups) validation using education and English proficiency (univariate general linear model) were also undertaken.

RESULTS

Participants (n = 202) had a mean (SD) age of 66.08 (10.93) years, 45.1% were male, and the mean (SD) total CADE-Q SV score was 13.07 (4.57). Reliability and consistency were good (intraclass correlation coefficient > 0.70; Cronbach α coefficients > 0.70, for total and per domain, respectively). The 5-domain structure was validated by confirmatory factor analysis. The scale demonstrated discriminant validity, with low education ( P < .001) and low English proficiency ( P = .017) associated with lower knowledge scores.

CONCLUSION

The CADE-Q SV (simplified Chinese version) can be used as a valid and reliable instrument, either paper based or digital, to evaluate the CHD-related knowledge of Chinese immigrants. This scale can be adapted to other migrant populations in the future.

Translation, cultural adaptation and psychometric validation of the Arabic short version of the coronary artery disease education questionnaire (CADE-Q SV) in Saudi Arabia

Objective

To translate, culturally adapt, and psychometrically validate the Arabic Coronary Artery Disease Education Questionnaire Short Version (CADE-Q SV).

Methods

The CADE-Q SV was translated to Arabic by two independent translators, followed by back-translation. Then, an expert panel of 10 healthcare providers and 10 patients reviewed the survey and provided input for content validity (CV) and clarity of items. For the psychometric analysis, 202 cardiac patients from Saudi Arabia completed the questionnaire, of which factor structure, internal consistency, construct, and criterion validity were assessed.

Results

Items were translated, and CV was confirmed. Items were rated based on relevance and understandability. The scale was finalized after changes in 5 items. Confirmatory factor analysis revealed 5 factors, all internally consistent: medical condition, risk factors, exercise, nutrition, and psychosocial health. Overall alpha was 0.84. Construct validity was established by significant associations between scores and occupation, educational level, family income, having a diagnosis of acute coronary syndrome or valve disorders and with a history of valve repair or replacement a coronary artery bypass graft procedure. Scores were significantly higher for those that participated in cardiac rehabilitation, confirming criterion validity.

Conclusions

Results from this study confirm the validity and reliability of the CADE-Q SV in Arabic-speaking patients.

Innovation

The CADE-Q SV can be used as a knowledge measurement to support clinical work and development of education intervention for Arabic patients.

Changes in disease-related knowledge and educational needs of patients with coronary heart disease over a six-month period between hospital discharge and follow-up

OBJECTIVE

To describe changes in the disease-related knowledge and educational needs of individuals with coronary heart disease (CHD).

METHODS

Patients hospitalized for CHD answered questionnaires about disease-related knowledge (Coronary Artery Disease Education Questionnaire-short version (CADE-Q-SV), score 0-20), educational needs (investigator-designed questions), health literacy (Short version of the European Health Literacy Survey Questionnaire (HLS-EU-Q16)), self-care (Self-Care of Coronary Heart Disease Inventory version (SC-CHDI)), and physical activity (Leisure-time Physical Activity Questionnaire) at discharge (T1) and six months later (T2).

RESULTS

Participants' (N = 308; mean [M] age=65.5 years [SD=8.7]; 81.5% male) knowledge scores increased from M= 13.8 (SD=3.2) to M= 14.8 (SD=2.8) (p < 0.001). At T1, educational level, age, health literacy, smoking, and self-care maintenance explained 14.5% of knowledge variability. At T2, these variables plus lack of awareness of CHD diagnosis explained 20.3% of the variability. Substantial educational needs were reported at both time points, although 89% received predischarge education.

CONCLUSION

The patients' educational needs were unfulfilled despite an increase in disease-related knowledge over time. Improved evidence-based patient education and follow-ups that address diagnosis, treatment, and self-care are needed.

PRACTICE IMPLICATIONS

Healthcare professionals can improve care of patients with CHD by providing focused patient education, prioritizing "need-to-know" topics and considering patients' health literacy.

Vietnamese Version of the General Medication Adherence Scale (GMAS): Translation, Adaptation, and Validation

Background: We aimed to translate, cross-culturally adapt, and validate the General Medication Adherence Scale (GMAS) into Vietnamese. Methods: We followed the guidelines of Beaton et al. during the translation and adaptation process. In Stage I, two translators translated the GMAS to Vietnamese. Stage II involved synthesizing the two translations. Stage III featured a back translation. Stage IV included an expert committee review and the creation of the pre-final version of the GMAS, and in stage V, pilot testing was conducted on 42 Vietnamese patients with type 2 diabetes. The psychometric validation process evaluated the reliability and validity of the questionnaire. The internal consistency and test–retest reliability were assessed by Cronbach’s alpha and Spearman’s correlation coefficients. The construct validity was determined by an association examination between the levels of adherence and patient characteristics. The content validity was based on the opinion and assessment score by the expert committee. The Vietnamese version of the GMAS was created, including 11 items divided into three domains. There was a good equivalence between the English and the Vietnamese versions of the GMAS in all four criteria. Results: One hundred and seventy-seven patients were participating in the psychometric validation process. Cronbach’s alpha was acceptable for all questionnaire items (0.817). Spearman’s correlation coefficient of the test–retest reliability was acceptable for the GMAS (0.879). There are significant correlations between medication adherence levels and occupation, income, and the Beliefs about Medicines Questionnaire (BMQ) score regarding construct validity. Conclusions: The Vietnamese version of GMAS can be considered a reliable and valid tool for assessing medication adherence in Vietnamese patients.
