SERRANI AZCURRA, Daniel. TRANSLATION, SPANISH ADAPTATION AND VALIDATION OF THE WARWICK-EDINBURGH WELL-BEING SCALE IN A SAMPLE OF ARGENTINE OLDER ADULTS. Act.Colom.Psicol. [online]. 2015, vol.18, n.1, pp.79-93. ISSN 0123-9155.  https://doi.org/10.14718/ACP.2015.18.1.8.

The study assesses psychometric properties and factorial structure of the Warwick-Edinburgh mental well-being scale after forward and backward translations and Spanish adaptation. The scale was validated by applying it to a sample of 910 Argentine elders, with ages ranging from 71 and 96 years (media 81.4 years; SD 10.9 years). The following measures were obtained: response distributions, internal consistency, test-retest reliability, construct validity and exploratory and confirmatory factor analysis. In four of the original items, phrasing was modified to keep conceptual equivalence with the original instrument. Reliability (Cronbach's alpha 0.89), item-total scale (0.41-0.78) and test-retest measured by intra-class correlation coefficient (ICC) (0.91) were deemed appropriate. Confirmatory factorial analysis showed a RMSEA = 0.054, considered acceptable, a CFI = 0.963, a NNFI = 0.925 (slightly below the accepted value) and a GFI = 0.991. A two factor solution was obtained so it was not possible to hold the single dimensional hypothesis as in the original scale. The translated and adapted scale shows an appropriate level of adjustment, high internal consistency and good test-retest reliability, with the same construct validity as the original instrument which allows its use among the elderly population.
