Is translation enough? : a study of the item characteristics which influence equivalence between English and Spanish versions of a selection test
Valentine, Andrea · 2013
The goal of this study was to investigate the equivalence between an English and Spanish version of a selection test that was used to hire entry-level employees for a nationwide retail organization. By using a test that was back translated from English to Spanish, this study aimed at understanding whether different item characteristics are related to differential item functioning (DIF) and whether these item characteristics moderate the degree of equivalence between IRT item parameters. An understanding of which item characteristics influence equivalence can help guide researchers and practitioners in deciding on which items require test adaptation and which can simply be translated without a substantial loss of equivalence.
