- Background: Health literacy (HL) is an important concept for patient education and disease management with heart failure (HF). However, research on HL has predominantly focused on functional HL (ability to read and write). The World Health Organization advocates evaluating comprehensive HL, including the ability to access information (communicative HL) and critically evaluate that information (critical HL).Objective: We developed an instrument for measuring functional, communicative, and critical levels of HL in patients with HF.Methods: We evaluated the reliability and validity of those 3 HL scales in a sample of 191 outpatients with HF (mean [SD] age, 66.9 [13.9] years; 64.9% males). Sociodemographic and clinical characteristics, knowledge of HF, a well as motivation to obtain health information were assessed for each patient through a self-administered questionnaire and review of electronic medical records.Results: We constructed scale items to reflect directly the comprehensive World Health Organization definition of HL. We identified 3 interpretable factors by exploratory factor analysis. Internal consistency was marginally acceptable for total HL (Cronbach [alpha] = 0.71), functional HL ([alpha] = 0.73), communicative HL ([alpha] = 0.68), and critical HL ([alpha] = 0.69); the interclass correlation coefficients of the functional, communicative, and critical HL subscales were 0.882, 0.898, and 0.882, respectively. Low functional, communicative, and critical HL was characteristic of older patients, those with lower socioeconomic status, patients living alone, those without a high school education, and patients lacking HF knowledge.Conclusions: Our new HL scale was demonstrated to be a reliable, valid instrument for measuring functional, communicative, and critical HL in patients with HF. Exploring a patient's HL level, including the ability to access, understand, and use health information as well as the ability to read and write, may provide better understanding of patients' potential barriers to self-care.

- Objective: Health literacy (HL) has been recognized as an important concept in patient education and disease management for heart failure (HF). However, previous studies on HL have focused predominantly on the relationships between functional HL (the ability to read and write), comprehensive HL including the ability to access information (communicative HL), and the ability to critically evaluate information (critical HL). Self-care behavior has not been evaluated. This study determined the relationship between functional, communicative, and critical HL and self-care behavior in HF patients. Methods: Cross-sectional analysis of the data was completed for HL, HF-related knowledge, and HF-related self-care behaviors. Sociodemographic and clinical characteristics were also assessed. Multivariate linear regression analysis was used to estimate the associations between literacy and self-care behavior. Results: 249 patients with HF were assessed (mean age, 67.7 +/- 13.9 years). Patients with low HL had poorer knowledge and self-care behavior than those with high HL. Critical HL was an independent determinant of self-care behavior (s beta = -0.154, P = 0.027). Conclusions: Critical HL was independently associated with self-care behavior in HF patients. Practice implications: Effective intervention should be developed to improve patient skills for critically analyzing information and making decisions. (C) 2016 Elsevier Ireland Ltd.
