“…Currently, the gender presents scientific, social, and cultural importance, with debates about the psychic response in various attributes that sometimes present prejudices and inaccuracies (Upchurch, 2020) and feed narra-tives loaded with ideology that in this aspect science and psychology should help to clear with evidence But in the case of the sciences, preliminary findings of gender differences without precise and reliable instruments are questionable, since they do not guarantee that the calibration represents equality of measurement between the groups. In this sense, is common in multi-group research that, when conducting comparative analyses, no prior verification of the ME of a measure is carried out in order to estimate inter-group discrepancies because, if they exist, it is unlikely to determine whether they are due to divergences in the interpretation of the items in the structure of the scale or to the characteristics of the groups themselves (Asparouhov & Muthén, 2014;Larzabal-Fernandez et al, 2023;Moreta-Herrera et al, 2021;Van de Schoot et al, 2015). The inability to account for the exact origin of the difference between groups leads to bias in the estimation of the final conclusions.…”
