GARCIA-CADENA, Cirilo H. et al. Validation of the Brief Interactive Optimism Scale-G in Mexico before COVID-19. Av. Psicol. Latinoam. [online]. 2021, vol.39, n.1, pp.1-14.  Epub 23-Set-2021. ISSN 1794-4724.  https://doi.org/10.12804/revistas.urosario.edu.co/apl/a.10504.

The primary objectives of this study were determining the construct, convergent, and discriminant validity of the Brief Interactive Optimism Scale-G (BIOS-G) in participants from six states of Mexico and estimating its internal consistency. In this study 3289 Mexicans participated (2028 men and 1243 women). The average age was = 30.43 years and SD = 10.52. Confirmatory factor analysis (CFA) and multiple regression analysis (MRA) were applied. There were appropriate fit indexes (e. g., CFI = .99; RMSEA = .07.). Convergent validity showed an r (3289) = .52 (p = < .01; d = medium), with the Satisfaction with Life Scale (SWLS) and the estimation of discriminant validity was r (3 289) r = -.19 with the Brief Scale for Assessing Anger Proneness (APS-G) (p = < .01; d = almost small), Alpha = .70 (3 289); p = < .01; omega = .76. The conclusion is that there is partial national evidence supporting the use of BIOS-G, because Mexico lacks a measure of this kind, being useful, at least, for research purposes.
