The fidelity of a translated survey instrument used to measure attitudes toward mental health was evaluated using statistical methods based on item response theory . Data from French and German versions of the attitude survey were analyzed, and items that displayed differential item functioning (dif) were identified. Item characteristic curves (ICCs) were examined to determine whether the source of dif could be attributed to errors in translation or differences in cultural experiences or knowledge. The proposal by Humphreys and Hulin for using ICCs to determine the source of dif is evaluated.
