Psychometric studies of the Eudemon Scale of Personal Well-being in adolescents

This study aims to evaluate the psychometric properties of the Eudemon Scale of Personal Well-being (EBP) in Brazilian adolescents. The participants were 1479 adolescents (64.7% girls) between 12 and 16 years old (M=14,12, SD=1,26). Participants answered the EBP and other instruments of well-being. The Exploratory Factor Analysis (n=712) indicated the presence of two factors and the internal consistency of the scale was adequate (α=0,767). The Confirmatory Factor Analysis (n=767) showed good fit indices of the scale with 21 items. Multigroup analyses indicated that the factor structure of the scale and the factor loadings of the items are similar for boys and girls. Significant correlations of the EBP were found with other scales that assess well-being through concurrent validation (Pearson correlations). It is possible to conclude that the instrument showed evidence of validity and it can be used with Brazilian adolescents.
