Adaptation and validation of the spanish version of the moral attentiveness scale

The present study adapted and validated Reynolds' (2008) Moral Attentiveness Scale (MAS) for use in Spanish populations (MAS-S). The adaptation process employed a committee approach to ensure linguistic and cultural appropriateness. The validation study ( N = 428) included exploratory and confirmatory factor analyses. The results supported the original two-factor structure, explaining 64.2 % of the variance ( χ 2 53 = 165, p < .001; CFI = 0.93; TLI = 0.91; RMSEA = 0.10). Reliability indices were high (Cronbach's α > 0.90). Convergent and discriminant validity evidence is provided through positive correlations between MAS-S dimensions and theoretically related constructs such as Social Justice Orientation and Empathic Concern and Personal Distress, while no significant associations were found with sacrificial moral dilemmas. These findings establish the MAS-S as a reliable and valid instrument for assessing moral attentiveness in Spanish contexts, with implications for advancing theoretical and practical research in moral psychology. • The MAS-S accuratly measures moral attentiveness in Spanish-speaking populations. • Validity evidence confirms the MAS's utility for assessing moral attentiveness. • Moral attentiveness is crucial to the development of morality theories.
