BACKGROUND Early intervention in a cardiorespiratory arrest by a witness significantly increases survival. That is why early training in cardiopulmonary resuscitation (CPR) may be essential. Therefore, the aim of this study is the development and validation of an instrument to assess CPR knowledge and skills for schoolchildren from 5 to 8 years old. METHOD We used a Spanish sample with 164 children aged between 5 and 8 years old. These children received a workshop called the "CPR from my school" program and their knowledge of CPR was assessed pre- and post-Workshop. We examined the scale through psychometric analyses within the framework of Classical Test Theory. RESULTS The Nonide Scale provided evidence of content validity, revealed an essentially unidimensional internal structure, as well as excellent reliability (Ω = .87). Furthermore, a significant improvement was observed in scores, before and after the CPR Workshop. CONCLUSIONS The Nonide Scale, designed to measure CPR knowledge and acquired skills in children from 5 to 8 years old, shows adequate psychometric properties, hence it can be used as professional and research contexts require.

5至8岁儿童的心肺复苏（CPR）：Nonide量表的心理测量特性。

背景技术由证人对心肺停止进行早期干预显着增加了存活率。这就是为什么心肺复苏（CPR）的早期培训可能必不可少的原因。因此，本研究的目的是开发和验证一种用于评估5至8岁学童的CPR知识和技能的工具。方法我们使用了一个西班牙样本，其中包括164名5至8岁的儿童。这些孩子参加了名为“我的学校的心肺复苏术”计划的讲习班，他们的心肺复苏术知识在工作坊之前和之后进行了评估。我们在古典测验理论的框架内通过心理测验分析了量表。结果Nonide量表提供了内容有效性的证据，揭示出本质上是一维的内部结构以及出色的可靠性（Ω= .87）。此外，在心肺复苏术研讨会之前和之后，在分数方面都观察到了显着的改善。结论Nonide量表旨在测量5至8岁儿童的CPR知识和后天技能，该表显示出足够的心理计量学性质，因此可以用于专业和研究环境。
