Abstract

Abstract This study aimed to gather psychometric evidence of the Scale of Positive and Negative Affects (EAPN-10) within the Brazilian context. Three studies were performed (N = 911). Study 1 considered 296 undergraduate students (MAge = 23.8; 59.1% females), who answered the EAPN-10 and a demographic questionnaire. Exploratory factor analysis revealed a two-factor structure [positive affects (α = .82) and negative affects (α = .81)], explaining 59.7% of the total variance. Study 2 took into account the participation of 313 undergraduate students (MAge = 23.3; 57.2% females), who answered the same instruments. Confirmatory 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 (MAge = 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 affects (α = .83) were positively correlated with well-being indicators, and negative affects (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 affects and their correlates within the Brazilian context.

Highlights

With well-being indicators, and negative affects (α = .80) were positively correlated with indicators of psychological discomfort
Along the lines of the aforementioned, we propose a brief measure, gathering evidence of its presumably two-factor structure and of the internal consistency of those factors
By way of multivariate analysis of variance (MANOVA), the group means for each item were compared, checking whether they would discriminate the participants with close magnitudes in the latent trait, which was confirmed [Wilks’ Lambda (10.258) = 0.31; p < .001, η2 = 0.69]
