SEGABINAZI, Joice Dickel et al. Positive and negative affect scale for adolescents: adaptation, standardization and validity evidence. Aval. psicol. [online]. 2012, vol.11, n.1, pp. 1-12. ISSN 1677-0471.

This study aimed to adapt a positive and negative affect scale for adolescents. Participants were 425 students, aged between 14 and 19 years. Students were tested in their classrooms. Principal component analysis revealed a bifactorial solution. The first factor, positive affect, had an eigenvalue of 8.1 and explained 29% of the total variance. The second factor, negative affect, had an eigenvalue of 3.6 and explained 12.4% of the total variance. Internal consistency, Cronbach’s alpha, was .88 for both positive and negative affect scales. Positive correlations were found between positive affect and self-esteem and life satisfaction. Negative correlations were found between negative affect and these two variables. In addition, males presented higher scores of positive affect, while females showed higher scores of negative affect. Local norms for interpreting scores are presented

Keywords : subjective well-being; life satisfaction scale; self-esteem; psychometrics.
