Abstract

Grit is one of the non-cognitive variables that has received the most attention in recent years given its relationship to and influence in various aspects of life. There are very few reliable, valid instruments to evaluate it in Spanish-speaking countries. Because of that, the aim of this study is the development and validation of a new scale to evaluate grit in Spanish-speaking contexts. We used a sample of 531 Spanish participants (60% women) from the general population (M_years = 38.60, SD_years = 14.90). We examined the structure and measurement invariance of the instrument. We calculated the instrument’s reliability and obtained evidence of validity in relation to other variables. We examined the differences in grit as a function of gender and age. The factorial analyses confirmed the unidimensionality of the instrument, along with the measurement invariance of the scores with respect to sex and age. The new grit scale demonstrated excellent reliability (α = .94; ω = .94). We found clear evidence of validity in relation to other variables; the Grit short scale (r = .691), self-control (r = .595), self-efficacy (r = .703), and conscientiousness (r = .661). The new scale for evaluating grit (Oviedo Grit Scale) is essentially unidimensional, and scores produced by it exhibit excellent indicators of reliability and validity.

摘要

砂砾是近年来受到最多关注的非认知变量之一，因为它与生活的各个方面都有关系和影响。在西班牙语国家，很少有可靠、有效的工具来评估它。正因为如此，本研究的目的是开发和验证一个新的量表，以评估西班牙语环境中的毅力。_{我们使用了来自普通人群（M年} = 38.60，SD_年）的 531 名西班牙参与者（60% 女性）的样本 = 14.90)。我们检查了仪器的结构和测量不变性。我们计算了该工具的信度，并获得了与其他变量相关的有效性证据。我们检查了作为性别和年龄函数的毅力差异。析因分析证实了该工具的单维性，以及分数在性别和年龄方面的测量不变性。新的砂砾量表表现出出色的可靠性（α = .94；ω = .94）。我们发现了与其他变量相关的明确证据；毅力短量表 (r = .691)、自我控制 (r = .595)、自我效能 (r = .703) 和尽责性 (r = .661)。用于评估毅力的新量表（Oviedo Grit Scale）本质上是一维的，它产生的分数表现出出色的信度和效度指标。
