GOUVEIA, Valdiney V. et al. Subjective Vitality Scale - SVS: evidences of its psychometric adequacy. Psic.: Teor. e Pesq. [online]. 2012, vol.28, n.1, pp.5-13. ISSN 0102-3772. http://dx.doi.org/10.1590/S0102-37722012000100002.
This paper presents empirical evidence of the psychometric adequacy of the Subjective Vitality Scale (SVS), based on three studies. In Study 1, 200 undergraduate students responded the SVS. The SVS showed a unidimensional factor structure (α = .73). In Study 2, another 200 undergraduate students answered the same instrument. A confirmatory factor analysis (CFA) confirmed the factor structure of Study 1, although item 2 was inadequate. Another CFA was realized without this item. Results were better than those considering all items (α = .75). Study 3 replicated these results with 200 elementary school teachers, and investigated the convergent validity of the SVS with satisfaction with life. It can be concluded that the SVS showed sufficient psychometric adequacy to support its use.
