This article reports the results of a study of potential sources of item nonequivalence between English and Chinese language versions of a cognitive development test for preschool-aged children. Items were flagged for potential nonequivalence through statistical and judgment-based procedures, and the relationship between flag status and item…

A linking design typically consists of a data collection procedure together with an item linking procedure that places item parameters calibrated from multiple test forms onto a common scale. This study considered 2 potentially useful item response theory linking designs. The first one is characterized by selecting a single set of common items…

When a test is adapted from a source language (SL) into a target language (TL), the two forms are usually not psychometrically equivalent. If linking between test forms is necessary, those items that have had their psychometric characteristics altered by the translation (differential item functioning [DIF] items) should be eliminated from the…

Because of the increased popularity of computerized adaptive testing (CAT), many admissions tests, as well as certification and licensure examinations, have been transformed from their paper-and-pencil versions to computerized adaptive versions. A major difference between paper-and-pencil tests and CAT from an examinee's point of view is that in…

Developed an Italian version of the Self-Description Questionnaire (SDQ-III) and studied the reliability and factorial validity of this translated instrument. Results show that the translated version has psychometric properties similar to those of the original English version. (SLD)

Illustrates how multidimensional scaling (MDS) and differential item functioning (DIF) procedures can be used to evaluate the equivalence of different language versions of an examination. Presents examples of structural differences and DIF across languages. (SLD)

Developed a method for evaluating cross-lingual equating and applied it to 12 forms of the Psychometric Entrance Test for admission to Israeli universities, a test translated from Hebrew into five languages. Discusses significance of the results and the differences between the two target-languages. (SLD)

Evaluated the structural equivalence and differential item functioning of an employee attitude survey from a large international corporation across three languages, eight cultures, and two mediums of administration. Results for 40,595 employees show the structure of survey data was consistent and items functioned similarly across all groups. (SLD)

Disentangled sources of differential item functioning (DIF) in a multilanguage assessment for which multiple factors were expected to be causing DIF. Data for the Third International Mathematics and Science study for four countries and two languages (3,000 to 11,000 cases in each comparison group) reveal amounts and sources of DIF. (SLD)

This study investigated the interaction between different cultural groups and item type, and the ensuing effect on construct validity for a psychological inventory, the Myers-Briggs Type Indicator (MBTI, Form G). The authors analyzed 94 items from 2 Chinese-translated versions of the MBTI (Form G) for factorial differences among groups of…

The increased use of computer-based and Internet-delivered testing has raised a number of ethical and legal issues. The International Test Commission's (this issue) Guidelines for Computer-Based and Internet-Delivered Testing represent the most recent attempt to provide test users, publishers, and developers with guidance regarding the appropriate…
