Testing the latent structure, factorial equivalence, and external correlates of the brief self-control scale in a community sample of Spanish adults Torres Marín, Jorge Gómez-Benito, Juana Guerrero, Estefania Guilera, Georgina Barrios, Maite 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. 2024-06-06T08:25:40Z 2024-06-06T08:25:40Z 2024-02-23 journal article Torres-Marín J, Gómez-Benito J, Guerrero E, Guilera G, Barrios M (2024) Testing the latent structure, factorial equivalence, and external correlates of the brief self-control scale in a community sample of Spanish adults.
