VIZIOLI, Nicolás Alejandro  e  PAGANO, Alejandro Emilio. Beck Anxiety Inventory: structural validity and reliability through different estimation methods in Argentine population. Act.Colom.Psicol.

Validity and reliability as psychometric properties consist of complex processes that must be constantly reviewed to ensure the correct use of a measurement instrument. Therefore, the present study investigated the structural validity, factorial validity, and reliability of the Beck Anxiety Inventory (BAI) in its Argentine adaptation, using different methods in a sample of 746 participants (Mean = 33.49, SD = 10.55) belonging to the city of Buenos Aires and the Buenos Aires suburbs, in Argentina. Specifically, confirmatory factor analyses were performed to test the one-, two- and four-dimensional models, using unweighted least squares, robust maximum likelihood, diagonal weighted least squares, and robust generalized least squares estimation methods. In addition, test-retest reliability was investigated using alpha, omega, algebraic and factorial GLB, H, beta, and theta. The results indicate that the unidimensional model showed better goodness-of-fit indices regard-less of the estimation method; and that all the reliability indices obtained were acceptable. This research provides strong evidence on the structural validity and reliability of the BAI.
