The Life Engagement Test (LET) consists of a fast instrument to measure the extent to which individuals identify and participate in valued activities and, therefore, engage in life. It is also a fundamental component of psychological well-being. This study aims to validate the Spanish version of the Life Engagement Test (LET-ES). First, the LET was translated using back-translation methodology, after which a pilot study was tested on 41 individuals. Then, the final version of the LET-ES was administered to a convenience sample of 436 Spanish participants (67,7 % female; 59,6 % aged 18 to 35 years old) to assess its reliability and validity. A subset of 138 participants (70,5 % female, 59,7 % aged 18 to 35 years old) completed a retest. Confirmatory factor analysis, reliability analysis (Cronbach's alpha, McDonald's omega), test-retest reliability (intraclass correlation coefficient), measurement invariance across gender and age, as well as convergent validity analyses were conducted. Results confirmed the one-factor structure of the LET-ES. Cronbach's alpha, McDonald's omega, and test-retest analysis yielded satisfactory reliability of the scale. Measurement invariance was established for gender, but not for age. Finally, convergent validity was supported by significant and positive correlations between the LET-ES scores and psychological well-being variables (i.e., purpose in life, satisfaction with life), and significant negative correlations between the LET-ES and psychological discomfort variables (i.e. stress, anxiety, depression). In conclusion, the Spanish version of the LET is a valid and reliable measure to assess life engagement among the Spanish population.
生活参与测试（LET）由一个快速的工具组成，用于衡量个体识别和参与有价值活动的程度，因此参与生活。它也是心理健康的一个基本组成部分。本研究旨在验证生活参与测试（LET-ES）的西班牙语版本。首先，使用回译方法对 LET 进行翻译，然后在 41 名个体中进行了预测试。然后，对 436 名西班牙参与者（67.7%为女性；59.6%年龄在 18 至 35 岁之间）进行了便利样本的最终版本的 LET-ES 测试，以评估其信度和效度。138 名参与者（70.5%为女性，59.7%年龄在 18 至 35 岁之间）完成了重测。进行了验证性因素分析、信度分析（Cronbach's alpha、McDonald's omega）、测试-重测信度（组内相关系数）、性别和年龄的测量不变性以及收敛效度分析。结果证实了 LET-ES 的单因素结构。Cronbach's alpha、McDonald's omega 和测试-重测分析得出了量表具有令人满意的信度。在性别方面建立了测量不变性，但在年龄方面没有。最后，LET-ES 分数与心理幸福感变量（即生活目的、生活满意度）之间存在显著正相关，与心理不适变量（即压力、焦虑、抑郁）之间存在显著负相关，支持了收敛效度。总之，LET-ES 的西班牙语版本是一种有效的、可靠的测量工具，可用于评估西班牙人群的生活参与度。
