Today, the importance of intercultural competence in both global and domestic contexts is well recognized. Bennett (1986, 1993b) posited a framework for conceptualizing dimensions of intercultural competence in his developmental model of intercultural sensitivity (DMIS). The DMIS constitutes a progression of worldview “orientations toward cultural difference” that comprise the potential for increasingly more sophisticated intercultural experiences. Three ethnocentric orientations, where one's culture is experienced as central to reality (Denial, Defense, Minimization), and three ethnorelative orientations, where one's culture is experienced in the context of other cultures (Acceptance, Adaptation, Integration), are identified in the DMIS.Based on this theoretical framework, the Intercultural Development Inventory (IDI) was constructed to measure the orientations toward cultural differences described in the DMIS. The result of this work is a 50-item (with 10 additional demographic items), paper-and-pencil measure of intercultural competence.Confirmatory factor analyses, reliability analyses, and construct validity tests validated five main dimensions of the DMIS, which were measured with the following scales: (1) DD (Denial/Defense) scale (13 items, alpha=0.85); (2) R (Reversal) scale (9 items, alpha=0.80); (3) M (Minimization) scale (9 items, alpha=0.83), (4) AA (Acceptance/Adaptation) scale (14 items, alpha=0.84; and (5) an EM (Encapsulated Marginality) scale (5 items, alpha=0.80). While no systematic gender differences were found, significant differences by gender were found on one of the five scales (DD scale). No significant differences on the scale scores were found for age, education, or social desirability, suggesting the measured concepts are fairly stable.
