  ABSTRACT: Introduction: The multidimensional psychological well-being model proposed by Ryff (RPWB) represents the widely used instrument to assess the human positive functioning by six interrelated dimensions. Previous studies have shown controversial results regarding the latent structure and factorial validity of the model. It was emphasized that, it is necessary to use particular methodological procedures that are appropriate for the treatment of ordinal variables. The aim of the research was to explore the dimensions of psychological well-being of RPWB, within the Italian context. Method: 602 adolescents attending high schools in the Florence area took part in the study. The data gathered with the Italian version of RPWB, were analyzed using polychoric correlations. Exploratory Factor Analyses, on the 54-, 42-, and 18-item versions, were conducted using the Maximum likelihood method for the extraction of factors, the Direct Oblimin for the rotation along with hierarchical analysis of oblique factors. Confirmatory Factor Analyses were conducted on the 18 items version. Results: Comparisons of 9 concurrent models through relative and absolute Goodness of Fit Indices, suggested that the most appropriate solutions were those with one or two second order factors and five or six first order factors correlated between them. Conclusions: Although, these results confirmed the multidimensionality of the instrument, in particular the substantial validity of the Ryff model; nevertheless further analyses are required in order to better clarify its nature and structure.
