Validation of the Low Self-Control Scale Spanish Version: a bifactor model approach.

General Theory of Crime has considered low self-control as the main cause of crime, and the Low Self-Control Scale (LSCS) is the tool derived from this theory to measure it. However, a debate exists about self-control dimensionality, and the LSCS has been used as a suitable tool in spite of this discussion. The present work explored the LSCS psychometric properties in 272 offender and non-offender adolescents from Argentina. Confirmatory factor analysis indicated that the scale is best represented by a bifactor structure, so a general latent self-control factor exists beyond its elements and vice versa. Internal consistency indexes were good to excellent for total and elements scores. Criterion validity analyses indicated that risk-seeking and self-centered subscales are associated with different types of deviance to the same extent as the total scale. The present study aims to provide new evidence on the use of the LSCS in research and professional practice.
