IDI General Information: The Intercultural Development Inventory (IDI)

The Intercultural Development Inventory® (IDI®) assesses intercultural competence—the capability to shift cultural perspective and appropriately adapt behavior to cultural differences and commonalities. Intercultural competence has been identified as a critical capability in a number of studies focusing on overseas effectiveness of international sojourners, international business adaptation and job performance, international student adjustment, international transfer of technology and information, international study abroad, and inter-ethnic relations within nations.

The Intercultural Development Inventory is a 50-item questionnaire available online that can be completed in 15–20 minutes. A wide range of organizations and educational institutions use the IDI (click here to view a number of organizations using the IDI). Thousands of Qualified Administrators in more than 30 countries have extensively applied the IDI in corporate, non-profit, government, faith-based, and educational contexts. In addition, more than 60 published articles and book chapters as well as over 66 Ph.D. dissertations have been completed using the IDI.

The IDI includes up to six (6) customized questions that can be added to the questionnaire. In addition, the IDI includes contexting questions that allow respondents to describe their intercultural experiences in terms of (a) their cross-cultural goals, (b) the challenges that they face navigating cultural differences, (c) critical (intercultural) incidents that they face when they encounter cultural differences, and (d) the ways they navigate those cultural differences. These questions allow individuals to reflect on how their IDI results relate to their cross-cultural goals and challenges, increasing cultural self understanding, and enabling improved accomplishment of key cross-cultural goals.

After individuals complete the IDI, each person’s responses to the 50 items are analyzed and reports are prepared that include the person’s written responses to the contexting questions.

An Education and Organization Version

The IDI is available in two different versions: one for use in educational institutions and the other in all other organizational settings. Each version is customized with different demographics questions as well as customized analysis of individual and group profile results.

Available in Multiple Languages

The IDI is available in 17 languages: Arabic, Bahasa Indonesian, Chinese, Czech, English, Finnish, French, German, Italian, Japanese, Korean, Norwegian, Portuguese, Russian, Serbian, Spanish, and Turkish. Each language version of the IDI has been rigorously “back translated,” ensuring both linguistic and conceptual equivalence in the meaning of each of the items.

Generates Customized Profile Reports

The IDI generates profiles of an individual’s intercultural competence (click here for a sample individual profile report). When used to assess an individual’s level of intercultural competence, a customized Intercultural Development Plan® (IDP®) is also prepared for the person. This IDP provides a detailed blueprint for the individual to further develop his/her intercultural competence (click here for a sample IDP report).

The IDI also generates group, subgroup, and organizational intercultural competence profiles (click here for a sample group profile report). When used to assess a group’s intercultural competence, interviews or focus groups can be conducted to identify cross-cultural goals and challenges, providing valuable information regarding how the group’s IDI profile translates into interculturally competent strategies across diverse groups.

A Valid Assessment Tool

The Intercultural Development Inventory has been psychometrically tested and found to possess strong validity and reliability across diverse cultural groups (click here for IDI validity overview results). This validity includes predictive validity within both the corporate and educational sectors. The IDI has been rigorously tested and has cross-cultural generalizability, both internationally and with domestic diversity.

Psychometric scale construction protocols were followed to ensure that the IDI is not culturally biased or susceptible to social desirability effects (i.e., individuals cannot “figure out” how to answer in order to gain a higher score).

The IDI possesses strong content and construct validity. Recent studies also indicate strong predictive validity of the IDI (click here for M.R. Hammer 2011 published IDI validation study results). In one study within the corporate sector, higher levels of intercultural competence, as measured by the IDI, were strongly predictive of successful recruitment and staffing of diverse talent in organizations. In another study, higher IDI scores among students were predictive of important study abroad outcomes, including greater knowledge of the host culture, less intercultural anxiety when interacting with culturally diverse individuals, increased intercultural friendships, and higher satisfaction with one’s study abroad experience.

The IDI is the assessment platform from which IDI Guided DevelopmentTM is undertaken to build intercultural competence based.
