To investigate cardiac self-efficacy and its predictors among patients with coronary artery diseases.
Patients with coronary artery diseases must perform the health behaviour to prevent recurrent cardiac events. It has been already well known that self-efficacy is a vital factor in both initiating and maintaining health behaviours.
Descriptive correlational and cross-sectional survey design.
Subjects were interviewed using structured study questionnaires. The data collected were statistically analysed by descriptive statistics and inferential statistics including the t-test, anova, Tukey's test, Pearson's correlation and hierarchical multiple regression analysis to determine the predictors of cardiac self-efficacy.
A convenience sample of 214 patients with coronary artery diseases was included. The mean age of subjects was 60·71 ± 10·07 years, and three-fourths were men. The overall model significantly explained 15·8% of variance in cardiac self-efficacy. Among predictors, occupation, diagnosis, body mass index, experience of receiving patient education and awareness of risk factors had statistically significant influences on cardiac self-efficacy.
Rather than disease knowledge, factors related to subject's perception were more likely to associate with cardiac self-efficacy. These findings might provide a theoretical basis to develop nursing interventions for enhancing cardiac self-efficacy of patients with coronary artery diseases.
Clinical nurses taking care of patients with coronary artery diseases should consider the patients' perception on their coronary artery diseases including experience of receiving patient education, and awareness of risk factors in encouraging the cardiac self-efficacy to promote the health behaviours for the secondary prevention of coronary artery diseases.
调查冠心病患者的心脏自我效能及其预测因素。
冠心病患者必须进行健康行为以预防心脏事件复发。自我效能感是启动和维持健康行为的重要因素，这一点已得到充分证实。
描述性相关性和横断面调查设计。
采用结构化研究问卷对受试者进行访谈。收集的数据采用描述性统计和推断性统计进行分析，包括 t 检验、方差分析、Tukey 检验、皮尔逊相关和分层多元回归分析，以确定心脏自我效能的预测因素。
纳入了 214 名冠心病患者的便利样本。受试者的平均年龄为 60.71 ± 10.07 岁，四分之三为男性。总体模型对心脏自我效能的解释率为 15.8%。在预测因素中，职业、诊断、体重指数、接受患者教育的经验和对危险因素的认识对心脏自我效能有统计学上的显著影响。
与疾病知识相比，与受试者感知相关的因素更有可能与心脏自我效能相关。这些发现可能为增强冠心病患者心脏自我效能的护理干预措施提供理论依据。
照顾冠心病患者的临床护士应考虑患者对冠心病的感知，包括接受患者教育的经验和对危险因素的认识，以鼓励心脏自我效能，促进二级预防冠心病的健康行为。
