“…As previous studies have pointed out [47], the COVID-19 pandemic forced the different educational institutions to transfer their classes to the virtual system, which also brought changes in interactions and students' perceptions of the instructional processes [47,69], and, in turn, could have had an impact on the construct validity of the instrument; however, the structure of the Spanish language version of the Life Skills Ability Scale, grouped into eight factors and a second order factor, corresponds to the original theoretical conception of the scale [2], which provides evidence of nomological validity. In this sense, studies that have tested construct validity in other instruments in the context of pandemics [70][71][72] have used confirmatory factor analyses, the same analyses performed in the present study. With respect to convergent validity, although, in this study, the scale presented was not associated with other instruments, it is possible to demonstrate that the relationships between the factors are positive and significant both in study 1 and 2, and between gender, while, with respect to discriminant validity, and although there was no other contrast instrument, it is possible to point out that, since there are significant differences between gender, the instrument presented is stable in the factors despite the differences between means, so it is capable of discriminating between gender.…”
