Here, we examine the psychometric properties of the Brief Self-Control Scale (BSCS) and its refined version (BSCS-R) among a forensic sample (n = 131) of incarcerated male youth and a school sample of male (n = 257) and female (n = 213) youth from Portugal. Confirmatory factor analysis indicated that the original one-factor structure of the BSCS and the refined two-factor structure of the BSCS-R obtained adequate fits. The BSCS demonstrated strong measurement invariance across gender and setting (forensic versus school), while the BSCS-R only revealed gender measurement invariance. The BSCS also tended to perform better that the BSCS-R in terms of other psychometric properties, including internal consistency measured by Alpha and Omega coefficients, discriminant and convergent validities, criterion validity, and known-groups validity. Findings support the use of the BSCS among justice-involved and community youth, but caution is advised regarding the use of its refined version in forensic settings.engDark triadTriarchic modelConcise measureGeneral-theoryGenderDelinquencyVictimizationPsychopathyAdolescentRiskjournal article10.1080/01639625.2019.1684942
