[Analysis of the gender variable in the EDTC using differential item functioning techniques]. / Análisis de la variable género en las escalas del EDTC mediante técnicas de funcionamiento diferencial de los ítems.

ABSTRACT

The aim of this work is to analyze the gender differences in the scales of a recently constructed test the so-called EDTC. This test measures the following traits sensation seeking, fearlessness, and impulsivity. Gender differences will be studied using Differential Item Functioning (DIF) techniques, in order to determine whether these differences are true differences in the assessed dimensions or if, on the contrary, they are the result of a mere artefact of the measuring instrument used. The methods used to study DIF are standardization, SIBTEST, logistic regression, Lord's chi 2 test, and indices based on the DFIT model. Despite the fact that some items with DIF exist, the gender differences observed seem to be the result of true differences in the measured personality constructs and they don't seem to be artificially produced by a bias in the test items.
