The Brief Self-Control Scale (BSCS) is a 13-item personality measure capturing how people differ in their capacity to exert self-control. Although the BSCS was originally regarded as a one-dimensional scale, subsequent psychometric studies have provided support for the empirical distinction of two and four interrelated but distinct components of self-control. Using a large sample of Spanish adults (n = 1,558; 914 female, 58.7%), we performed a comprehensive data-driven comparison of the most well-established item-level latent structures for the BSCS. Results showed that the differentiation between general self-discipline and impulse control offered a better fit to the observed data than did the unidimensional representation of self-control. This two-dimensional structure for the BSCS scores was also supported in terms of its internal consistency, measurement invariance across gender and age groups, and meaningful correlations with wellbeing-related indicators and Big Five personality traits. Plausible implications of these findings are discussed.
简要自我控制量表（BSCS）是一种 13 项人格测试，用于衡量人们在自我控制能力方面的差异。尽管 BSCS 最初被视为一个单维量表，但随后的心理测量研究为自我控制的两个和四个相互关联但不同的组成部分的经验区分提供了支持。本研究使用了大量西班牙成年人的样本（n=1558；914 名女性，58.7%），对 BSCS 最成熟的项目层面潜在结构进行了全面的数据驱动比较。结果表明，与自我控制的单一维度表示相比，一般自我约束和冲动控制之间的区分更符合观察到的数据。BSCS 分数的这种二维结构在内部一致性、跨性别和年龄组的测量不变性以及与幸福感相关指标和大五人格特质的有意义相关性方面也得到了支持。讨论了这些发现的可能意义。
