According to the literature, the use of the Berkeley Puppet Interview (BPI) to measure Big Five personality traits in children provides reliable and valid scores. However, the implementation of the BPI could be costly, especially when working with large sample sizes. Big Five self-reports were collected from 1118 Mexican children aged 7–8 years using a modified version of the BPI protocol and a Spanish version of the Big Five questionnaire. The main objective of this study was to inquire whether some modifications in the application protocol of the BPI could still provide reliable personality scores for the population under study. We report item–rest correlation, Cronbach’s alpha and omega as reliability measures, and confirmatory factor analytic models to investigate dimensionality. The results show that the personality trait scores are markedly reliable and that the dimensionality of the instrument holds for the Mexican sample.

根据文献，使用伯克利木偶面试（BPI）来测量儿童的五种人格特质可提供可靠且有效的分数。但是，BPI的实施成本可能很高，尤其是在处理大样本量时。使用修订后的BPI协议版本和西班牙版的“大五国”问卷，从1118名7-8岁的墨西哥儿童中收集了“大五国”自我报告。这项研究的主要目的是询问对BPI应用协议的某些修改是否仍可以为所研究的人群提供可靠的人格评分。我们报告了项目-休息相关性，Cronbach的alpha和omega作为可靠性度量，以及用于研究维数的确认性因子分析模型。
