MORAN, Valeria Estefanía et al. IPIP-NEO Inventory: Stability and Internal Structure, Convergent and Concurrent Validity in Argentinean Samples. Acta de investigación psicol [online]. 2020, vol.10, n.2, pp.27-42.  Epub Mar 05, 2021. ISSN 2007-4719.  https://doi.org/10.22201/fpsi.20074719e.2020.2.344.

The main personality assessment tools were built on the theoretical basis of the Five Factors model. Particularly, in Argentina, IPIP-NEO is one of the instruments, based on this model, that presents satisfactory results in the studies of internal consistency (reliability) and validity through evidence of internal structure (exploratory factor analysis). The aim of this work was to contribute new psychometric studies to the scale using a heterogeneous sample of Argentinean (N = 499). The temporal stability of the scores was estimated through the test-retest method and an internal structure validity study was performed by confirmatory factor analysis. On the other hand, external validity was provided through convergence studies, contrast studies of groups divided by sex and age, and a test criterion analysis through multiple regression with recreational activities. The results suggest that the IPIP-NEO scores are stable, with adequate reliability indices and evidence of external validity, indicating that it can be used in Argentine samples. The development of a local scale and new studies of external validity with clinical and labor implications are planned.
