    ABSTRACT: Background: The lack of tools to measure heart failure patients' knowledge about their syndrome when participating in rehabilitation programs demonstrates the need for specific recommendations regarding the amount or content of information required. Objectives: To develop and validate a questionnaire to assess heart failure patients' knowledge about their syndrome when participating in cardiac rehabilitation programs. Methods: The tool was developed based on the Coronary Artery Disease Education Questionnaire and applied to 96 patients with heart failure, with a mean age of 60.22 ± 11.6 years, 64% being men. Reproducibility was obtained via the intraclass correlation coefficient, using the test-retest method. Internal consistency was assessed by use of Cronbach's alpha, and construct validity, by use of exploratory factor analysis. Results: The final version of the tool had 19 questions arranged in ten areas of importance for patient education. The proposed questionnaire had a clarity index of 8.94 ± 0.83. The intraclass correlation coefficient was 0.856, and Cronbach's alpha, 0.749. Factor analysis revealed five factors associated with the knowledge areas. Comparing the final scores with the characteristics of the population evidenced that low educational level and low income are significantly associated with low levels of knowledge. Conclusion: The instrument has satisfactory clarity and validity indices, and can be used to assess the heart failure patients' knowledge about their syndrome when participating in cardiac rehabilitation programs.

    ABSTRACT: Objectives To translate, culturally adapt and psychometrically validate the Information Needs in Cardiac Rehabilitation (INCR) tool to Portuguese. Background The identification of information needs is considered the first step to improve knowledge that ultimately could improve health outcomes. Methods The Portuguese version generated was tested in 300 cardiac rehabilitation patients (CR) (34% women; mean age = 61.3 ± 2.1 years old). Test-retest reliability was assessed using intraclass correlation coefficient (ICC), the internal consistency using Cronbach's alpha, and the criterion validity was assessed with regard to patients' education and duration in CR. Results All 9 subscales were considered internally consistent (á > 0.7). Significant differences between mean total needs and educational level (p < 0.05) and duration in CR (p = 0.03) supported criterion validity. The overall mean (4.6 ± 0.4), as well as the means of the 9 subscales were high (emergency/safety was the greatest need). Conclusion The Portuguese INCR was demonstrated to have sufficient reliability, consistency and validity.

    ABSTRACT: Cardiovascular diseases (CVD) are the leading cause of mortality in middle-income countries, such as Brazil. However, given the diversity in health care systems in Brazil, access to proven services, such as cardiac rehabilitation (CR), varies widely. TO DESCRIBE AND COMPARE MULTILEVEL BARRIERS TO CR ENROLLMENT AND PARTICIPATION IN THREE BRAZILIAN COHORTS: (1) cardiac outpatients not attending CR (public or private system); (2) cardiac outpatients paying for CR; and (3) residents at high-risk of CVD with access to a free comprehensive exercise program but not making use of the program. Brazilian residents from two cities were invited to participate - Florianopolis, an urban center; and Luzerna, a rural center. Respondents completed a survey including the Cardiac Rehabilitation Barriers Scale. Mann-Whitney U tests were used to compare barriers between cohorts cross-sectionally. Six hundred twenty-eight Brazilians consented to participate: 237 (37.7%) from Florianopolis, of which 139 (22.1%) participated in CR; and 391 (62.3%) from Luzerna. The mean total CR barriers for the sample were 1.66 ± 0.6 and differed significantly by cohort (P < 0.001). CR nonattendees from Florianopolis (eg, distance and not knowing about CR) and participants from Luzerna (eg, work and family responsibilities) reported significantly higher barriers than CR attendees from Florianopolis. CR nonattendees reported significantly greater barriers than CR attendees. It is hoped that the provision of CR will increase, and that the development of the programs will be in a manner which mitigates the chief barriers identified herein.

    ABSTRACT: Cardiovascular diseases show high incidence and prevalence in Brazil; however, participation in Cardiac Rehabilitation (CR) is limited and has been poorly investigated in the country. The Cardiac Rehabilitation Barriers Scale (CRBS) was developed to assess the barriers to participation and adherence to CR. To translate, cross-culturally adapt and psychometrically validate CRBS to Brazilian Portuguese. Two independent initial translations were performed. After the reverse translation, both versions were reviewed by a committee. The new version was tested in 173 patients with coronary artery disease (48 women, mean age = 63 years). Of these, 139 (80.3%) participated in CR. Internal consistency was assessed by Cronbach's alpha, test-retest reliability by intraclass correlation coefficient (ICC) and construct validity by factor analysis. T-tests were used to assess criterion validity between participants and non-participants in CR. The applied test results were evaluated regarding patient characteristics (gender, age, health status and educational level). The Brazilian Portuguese version of the CRBS had Cronbach's alpha of 0.88, ICC of 0.68 and disclosed five factors, most of which showed to be internally consistent and all were defined by the items. The mean score for patients in CR was 1.29 (SD = 0.27) and 2.36 for ambulatory patients (SD = 0.50) (p <0.001). Criterion validity was also supported by significant differences in total scores by gender, age and educational level. The Brazilian Portuguese version of CRBS has shown adequate validity and reliability, which supports its use in future studies.
