ResumoThis study aimed to gather psychometric evidence of the Scale of Positive and Negative Aff ects (EAPN-10) within the Brazilian context.Three studies were performed (N = 911).Study 1 considered 296 undergraduate students (M Age = 23.8;59.1% females), who answered the EAPN-10 and a demographic questionnaire.Exploratory factor analysis revealed a two-factor structure [positive aff ects (α = .82)and negative aff ects (α = .81)],explaining 59.7% of the total variance.Study 2 took into account the participation of 313 undergraduate students (M Age = 23.3;57.2% females), who answered the same instruments.Confi rmatory factor analysis corroborated the two-factor structure (e.g., CFI = .92),which was invariant across males and females (e.g., ΔCFI < .01),with alphas greater than .70.Finally, Study 3's participants were 302 university students (M Age = 23.1;54.3% females), who answered the aforementioned instruments as well as measures of vitality, positivity, optimism, anxiety, depression and stress.Supporting their criterion validity, positive aff ects (α = .83)were positively correlated Trends Psychol., Ribeirão Preto, vol.27, nº 1, p. 189-203 -March/2019 with well-being indicators, and negative aff ects (α = .80)were positively correlated with indicators of psychological discomfort.In conclusion, the EAPN-10 is a psychometrically adequate measure that can be employed to assess people's aff ects and their correlates within the Brazilian context.
