背景：有人认为，只有12%的成年人具备必要的卫生知识，可以有效地管理他们的卫生保健，这可能导致自我保健活动的困难，如药物依从性。先前的研究表明，健康素养可能会影响知识，自我效能和自我保健，但这还没有得到充分的检验。目的：检验一个模型来解释健康素养、心力衰竭知识、自我效能感和自我保健之间的关系。方法：在接受以临床为基础的教育之前，新转诊到3家心力衰竭诊所的患者完成了健康素养、心力衰竭知识、自我效能感、自我保健和人口统计学的评估。完成结构方程建模以检验变量间关系的强度。结果：在81名参与者中，63名患者的数据是完整的。健康素养与知识独立相关（P < 0.001）。健康素养与自我保健无关。自我效能感与自我护理依从性独立相关（P = 0.016）。其他关系无统计学意义。模型具有较好的拟合性（比较拟合指数= 1.000），可以解释33.6%的知识方差和27.6%的自我保健方差。结论：健康素养影响心力衰竭知识，但不影响自我护理依从性。相反，自我效能感会影响自我护理依从性。未来的研究应纳入其他因素，以更好地模拟健康素养、知识、自我效能和自我保健之间的关系。(C) 2014爱思唯尔公司版权所有。
Background: It has been argued that only 12% of adults have the necessary health literacy to manage their health care effectively, which can lead to difficulties in self-care activities, such as medication adherence. Prior research suggests that health literacy may influence knowledge, self-efficacy and self-care, but this has not been fully examined.Objective: To test a model to explain the relationships between health literacy, heart failure knowledge, self-efficacy, and self-care.Methods: Prior to receiving clinic-based education, newly referred patients to 3 heart failure clinics completed assessments of health literacy, heart failure knowledge, self-efficacy, self-care, and demographics. Structural equation modeling was completed to examine the strength of the inter-variable relationships.Results: Of 81 participants recruited, data from 63 patients were complete. Health literacy was independently associated with knowledge (P < 0.001). Health literacy was not related to self-care. Self-efficacy was independently-associated with self-care adherence (P = 0.016). No other relationships were statistically significant. The model had good fit (comparative fit index = 1.000) and explained 33.6% of the variance in knowledge and 27.6% in self-care.Conclusions: Health literacy influences knowledge about heart failure but not self-care adherence. Instead, self-efficacy influenced self-care adherence. Future research should incorporate additional factors that may better model the relationships between health literacy, knowledge, self-efficacy, and self-care. (C) 2014 Elsevier Inc.
