Cardiopulmonary resuscitation (CPR) has recently been added to the school curriculum worldwide and is currently taught to students between the ages of 10 and 16 years. The effect of the age of trainees on their satisfaction with CPR training has yet been elucidated. The aim of this study was to compare the satisfaction of trainees of different ages who participated in CPR training in schools in Japan. In total, 392 primary school students (10-11 years old), 1798 junior high school students (12-13 years old), and 4162 high schools students (15-16 years old) underwent the same 3-h course of CPR training, according to the guidelines of 2000 for Emergency Cardiovascular Care and CPR. The course was evaluated by a questionnaire completed by the participants. Primary school students responded most positively to all questions, including those reflecting enjoyment and the confidence of participants to apply CPR (Jonckheere-Terpstra test: P < 0.01). Exploratory factor analysis defined three latent variables (reaction, concentration, and naïveté) based on the seven variables addressed in the questionnaire. In the causal relationships analyzed by structural equation modeling (SEM), naïveté (which is related to age) directly affected the other latent variables. The current model suggested that the students' satisfaction with CPR training was strongly related to their age. Primary school students enjoyed CPR training more and were more confident in their ability to perform CPR than junior high and high school students were. Therefore, children aged 10-11 years may be the most appropriate candidates for the introduction of CPR training in schools.
心肺复苏术（CPR）最近已被纳入全球学校课程，目前面向10至16岁的学生进行教学。培训学员的年龄对其心肺复苏培训满意度的影响尚未阐明。本研究的目的是比较在日本学校参加心肺复苏培训的不同年龄段学员的满意度。根据2000年《心血管急救和心肺复苏指南》，总共392名小学生（10 - 11岁）、1798名初中生（12 - 13岁）和4162名高中生（15 - 16岁）接受了相同的3小时心肺复苏培训课程。该课程通过参与者填写的问卷进行评估。小学生对所有问题的回答最为积极，包括那些反映参与度和参与者实施心肺复苏信心的问题（Jonckheere - Terpstra检验：P < 0.01）。探索性因素分析基于问卷中的七个变量定义了三个潜在变量（反应、注意力和天真）。在通过结构方程模型（SEM）分析的因果关系中，天真（与年龄相关）直接影响其他潜在变量。当前模型表明，学生对心肺复苏培训的满意度与其年龄密切相关。小学生比初中生和高中生更喜欢心肺复苏培训，并且对自己实施心肺复苏的能力更有信心。因此，10 - 11岁的儿童可能是学校引入心肺复苏培训的最合适人选。
