: In this study, we aimed to analyze the validity, based on the internal structure of the construct, measurement invariance by sex, and reliability of the scores for the "Knowledge in Basic Cardiopulmonary Resuscitation in Peruvian children/adolescents" (KBCPR_P21) and "Attitudes in Basic Cardiopulmonary Resuscitation in Peruvian children/adolescents" (ABCPR_P21) instruments in Spanish. : A cross-sectional and instrumental methodological study was conducted between February and August 2021, with the participation of 415 Peruvian elementary school students between 8 and 13 years of age. Participants responded to surveys on knowledge and attitudes toward CPR. For both instruments, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) was used as the estimation method for categorical data. : All of the items for both scales have high discriminative capacity (>0.30), and both scales showed high internal consistency (Cronbach's alpha > 0.87 and McDonald's omega > 0.90). The validity, based on the internal structure of the construct, implied the existence of a single factor grouping all the items in the two scales (CFI and TLI > 0.95; RMSEA and SRMR < 0.08). Multigroup confirmatory factor analysis also allowed us to satisfactorily verify measurement invariance by sex at the four levels (configural, metric, scalar, and strict) for both scales. : We can conclude that the values obtained in our evaluation of the scales favor considering them as valid and reliable instruments with which to measure knowledge and attitudes toward basic cardiopulmonary resuscitation in children/adolescents in Peru, given prior learning. The scales could also be used in the evaluation of knowledge and attitudes around basic cardiopulmonary resuscitation in other countries, providing trainers with rapid feedback on the knowledge and attitudes transmitted in training courses, thus allowing better control over the training activities carried out in these courses. Finally, the availability of the scales would allow researchers to empirically test their psychometric properties in other countries.
在本研究中，我们旨在基于结构的内部结构、按性别划分的测量不变性以及西班牙语版“秘鲁儿童/青少年基本心肺复苏知识”（KBCPR_P21）和“秘鲁儿童/青少年基本心肺复苏态度”（ABCPR_P21）工具得分的可靠性，分析其有效性。
2021年2月至8月进行了一项横断面和工具性方法学研究，有415名8至13岁的秘鲁小学生参与。参与者对关于心肺复苏知识和态度的调查问卷做出回应。对于这两种工具，探索性因素分析（EFA）和验证性因素分析（CFA）被用作分类数据的估计方法。
两个量表的所有项目都具有较高的区分能力（>0.30），并且两个量表都显示出较高的内部一致性（克朗巴哈α系数>0.87，麦克唐纳ω系数>0.90）。基于结构的内部结构的有效性意味着存在一个单一因素将两个量表中的所有项目分组（CFI和TLI>0.95；RMSEA和SRMR<0.08）。多组验证性因素分析还使我们能够令人满意地验证两个量表在四个水平（构型、度量、标量和严格）上按性别划分的测量不变性。
我们可以得出结论，鉴于先前的学习情况，我们对量表评估中获得的值有利于将它们视为有效且可靠的工具，用于测量秘鲁儿童/青少年对基本心肺复苏的知识和态度。这些量表也可用于评估其他国家围绕基本心肺复苏的知识和态度，为培训人员提供关于培训课程中所传授知识和态度的快速反馈，从而更好地控制这些课程中开展的培训活动。最后，这些量表的可用性将使研究人员能够在其他国家实证检验其心理测量特性。
