[Factorial confirmatory models of Ryff's scales in a sample of elderly people].

Several recent works have analysed the factorial structure of well-being measures. The aim of our study is to analyse the factorial structure of a widely used well-being scale, Ryff's Scales of Psychological Well-being, but in a specific subpopulation of the Spanish population, the elderly. For this particular subpopulation, the construct of well-being has been employed in most theoretical models that explain quality of life, and its role is therefore pivotal. The sample comprised 169 elderly people (65 years or more), sampled within the Valencian Community. The 54-item version of Ryff's scales was used. An item parcelling process was analytically employed before confirmatory factor analyses, allowing a total of 18 well-being indicators. Confirmatory factor analyses were specified and tested, including all theoretical and empirical solutions found in the literature, either in the general population or in specific populations of different cultural contexts. Goodness-of-fit results were similar to the ones found in the literature. Best solutions were a six-factor model with correlated factors, as defended by the authors, and a five-factor correlated solution, collapsing environmental mastery and self-acceptance into a single factor.
