This study utilized a Differential Item Functioning (DIF) methodology for examining translated tests wherein all the examinees have the same native language -the target language of the translation- in order to provide information about the psychometric equivalence of the original and translated versions of the tests at item level. This study has also found possible explanations for translation DIF in certain types of items.
