This study examined the mediation effect of practical training on the relationship of demographic characteristics with bystander self-efficacy in cardiopulmonary resuscitation (CPR) performance. We used nationwide, cross-sectional data from the Korea Community Health Survey and analyzed 25,082 Korean adults who participated in CPR training within the last 2 years. A mediation model was applied to explore the pathway from demographic characteristics via CPR practical training to self-efficacy in CPR performance. A multiple logistic regression analysis was performed to examine each path in the mediation model. Of the 25,082 respondents recently trained, 19,168 (76.8%) practiced on a manikin. In the unadjusted CPR practical training model, the demographic characteristics associated with high self-efficacy in CPR performance were male gender (odds ratio [OR] = 2.54); 50s age group (OR = 1.30); college or more (OR = 1.39) and high school education (OR = 1.32); white collar (OR = 1.24) and soldier (OR = 2.98) occupational statuses. The characteristics associated with low self-efficacy were 30s age group (OR = 0.69) and capital (OR = 0.79) and metropolitan (OR = 0.84) areas of residence (p < 0.05). In the adjusted CPR practical training model, the significance of the relationship between demographics and self-efficacy in CPR performance decreased in male gender, 30s age group, college or more and high school education, and soldier occupational status (i.e., partial mediation), and disappeared in metropolitan residents (i.e., complete mediation). The degree of the mediating effect of CPR practical training on self-efficacy differed for each demographic characteristic. Thus, individualized educational strategies considering recipient demographics are needed for effective practice-based CPR training and improving bystander CPR performance.
本研究考察了实践培训对心肺复苏术（CPR）表现中旁观者自我效能与人口统计学特征之间关系的中介效应。我们使用了全国性的横断面数据，即韩国社区健康调查，并分析了在过去 2 年内参加过 CPR 培训的 25082 名韩国成年人。采用中介模型探讨了从人口统计学特征到 CPR 实践培训再到 CPR 表现自我效能的途径。采用多元逻辑回归分析检验了中介模型中的每条路径。在最近接受培训的 25082 名受访者中，有 19168 人（76.8%）在模型上进行了实践。在未调整的 CPR 实践培训模型中，与 CPR 表现自我效能较高相关的人口统计学特征是男性（优势比[OR] = 2.54）；50 多岁年龄组（OR = 1.30）；大学及以上学历（OR = 1.39）和高中学历（OR = 1.32）；白领（OR = 1.24）和军人（OR = 2.98）职业状态。与自我效能较低相关的特征是 30 多岁年龄组（OR = 0.69）和首都（OR = 0.79）以及大都市（OR = 0.84）地区的居住者（p < 0.05）。在调整后的 CPR 实践培训模型中，人口统计学特征与 CPR 表现自我效能之间的关系在男性、30 多岁年龄组、大学及以上学历和高中学历以及军人职业状态方面的重要性降低（即部分中介），而在大都市居民方面则消失（即完全中介）。CPR 实践培训对自我效能的中介效应程度因人口统计学特征而异。因此，需要根据接受者的人口统计学特征制定个性化的教育策略，以实现有效的基于实践的 CPR 培训和提高旁观者的 CPR 表现。
