While cross-cultural research has posited the importance of intercultural competence in both global and domestic contexts, work by Bennett (1986, 1993b) has additionally suggested an underlying theoretical framework, which he calls the Developmental Model of Intercultural Sensitivity (DMIS), for conceptualizing intercultural sensitivity and competence. This theoretical framework provided conceptual guidance as we undertook the construction of the Intercultural Development Inventory (IDI) to measure the orientations toward cultural differences described in the DMIS. The result of this work is a 50-item, paper-and-pencil instrument (with 10 additional demographic items). (author abstract)
