Intercultural Development Inventory

The Intercultural Development Inventory

We use the Intercultural Development Inventory (IDI) with many clients who are seeking to measure individual and team adaptability to differences. The IDI is a highly validated, confidential 3rd-party assessment accessed online. We have a team of Qualified Administrators to administer the assessment and provide group and individual debriefs. The IDI has been a well-received tool across client organizations.

About the Intercultural Development Inventory (IDI)

The Intercultural Development Inventory (IDI) is an online assessment tool which helps individuals and teams assess and reflect on their stages of cultural sensitivity. The IDI was developed by Dr. Mitchell Hammer and Dr. Milton Bennett as an empirical measurement of intercultural sensitivity, as conceptualized by Bennett’s Developmental Model of Intercultural Sensitivity (DMIS).

The DMIS has been used extensively in intercultural education and training since 1986 as a framework for explaining the reactions of people to cultural difference. The DMIS identifies a set of cognitive structures (or “worldviews”) that act as orientations to cultural difference which move along a developmental scale from stages of ethnocentrism through stages of ethnorelativism. The IDI is a valid, reliable tool to measure an individual’s (or group’s) fundamental worldview orientation to cultural difference according to the DMIS stages.

What is the IDI?

  • A theory-based (not opinion-based) inventory which meets standard scientific criteria for a valid and reliable psychometric instrument

  • A 50-item questionnaire available in 15 languages

  • It is accessed online

  • The IDI is currently being used by over 2500 Qualified Administrators in more than 25 countries

Why use the IDI?

  • To assess cross-cultural competencies for teams or individuals working in cross-cultural situations

  • To understand and identify developmental stages of clients or partners

  • To encourage reflection and strategizing for multicultural teams

  • To determine areas that facilitate, or limit, cross-cultural competence for teams or individuals

  • To increase self-awareness of intercultural competencies and encourage further development

What is the purpose of the IDI?
The IDI can help respondents to:

  • Understand the developmental stages of intercultural sensitivity through which people move towards greater intercultural effectiveness

  • Increase self-awareness for each individual respondent and identify issues that may be impeding development

  • Increase organization-level understanding of intercultural issues

  • Determine training and educational needs

  • Evaluate the effectiveness of training, counselling and education endeavours

  • Improve intercultural skills

  • Prepare to enter a new culture, such as a multinational environment, a new country or a domestic situation with cultural diversity

  • Identify training and education needs of client populations

How does it work?

  • Participants complete a confidential (password accessed) online inventory

  • A Qualified IDI Administrator creates a graphic profile (for a group or individuals)

  • IDI Administrator explains stages of the Developmental Model of Intercultural Sensitivity (DMIS) which is the theoretical base of the instrument

  • IDI Administrator provides graphic profile and interpretation

  • Teams or individuals reflect on results of inventory, strategize for further development and achieve greater understanding of reactions to cultural difference
