TEZZA, Rafael; BORNIA, Antonio Cezar; SPENASSATO, Débora  e  TRIERWEILLER, Andréa Cristina. EMPIRICAL COMPARISON OF THE MULTIDIMENSIONAL MODELS OF ITEM RESPONSE THEORY IN E-COMMERCE. Pesqui. Oper. [online]. 2016, vol.36, n.3, pp.503-532. ISSN 1678-5142.  https://doi.org/10.1590/0101-7438.2016.036.03.0503.

The measurement of latent traits within the organizational field such as quality, effectiveness and learning has been conducted in several formats using a wide variety of quantitative methods, including Item Response Theory that consistently increased in organizational studies. The purpose of this article is to compare the hierarchical and non-hierarchical structures of three multidimensional models of ItemResponse Theory, based on the interface quality measurement in e-commerce sites. We compared the multiple unidimensional, compensatory multidimensional and bifactorial models, and also elaborated and applied 75 items in a sample of 441 e-commerce websites. As a result, we conducted a discussion of the latent construct, the quality in e-commerce and its multidimensional configuration to adjust and compare three multidimensional models.

Palavras-chave : multidimensional Item Response Theory; latent trait; measurement; websites; organizations.
