Spanish adaptation of the Self-Control Scale and the Brief Self-Control Scale and evidences of validity in university population

The aim of the study was to adapt and validate the Self-Control Scale (SCS) and the Brief Self-Control Scale (BSCS) for the Spanish-speaking population. We worked with a sample of 430 students from the National University of Mar del Plata (279 women and 151 men) with an average age of 23.38 (SD = 5.69). The Exploratory Factor Analysis revealed in the SCS a three-factor structure. The factors were named as Non-reflective control of impulses, Self-discipline and Reflective control of impulses. In the BSCS, a two-factor structure was found. Factors were named Self-Discipline and Control of the impulses. Both the SCS and the BSCS presented good model fit index and adequate values of internal consistency. Evidence of concurrent and convergent validity is also presented through associations with measures of impulsivity and responsibility, respectively. It is concluded that both scales are valid for the population under study.
