GOUVEIA, Valdiney V. et al. Scale of Positive and Negative Aff ects (EAPN-10): evidence of its psychometric adequacy. Temas psicol. [online]. 2019, vol.27, n.1, pp. 189-203. ISSN 1413-389X.  http://dx.doi.org/10.9788/TP2019.1-14.

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.
