ABAL, Facundo Juan Pablo; AUNE, Sofía Esmeralda  and  ATTORRESI, Horacio Félix. Construcción de un banco de ítems de facetas de neuroticismo para el desarrollo de un test adaptativo. Rev. psicodebate: psicol. cult. soc. [online]. 2019, vol.19, n.1, pp.31-50. ISSN 24516600.

The goal of this work was to elaborate a bank of items to measure the facets of neuroticism on the basis of the Five-Factor Model (McCrae & Costa, 2010) and the feasibility of adaptive administration was examined. The study began with a pool of 90 items which was then reduced to 54 (nine per facet) through expert judgment and a pilot study. The refined version was administered to 1147 adults in the general population of Buenos Aires metropolitan area (52.7% women). Seventy percent of the cases were used to: a) calibrate the items of each facet separately with Samejima’s (2010) Graded Response Model, b) verify internal structure of bank through Confirmatory Factorial Analysis and c) obtain evidence of concurrent validity. Facets ordinal alpha ranged between .76 and .87. With the remaining 30% of cases, an adaptive administration simulation was carried out considering an estimation error ≤ 0.50 as stopping criteria. It is concluded that the bank collects evidence of acceptable validity and reliability for its administration in a conventional format but requires the incorporation of more items to optimize the Impulsiveness, Vulnerability and Angry Hostility facets measurement.
