Frequently Asked Questions

IDI Overview
1. What is the IDI® Assessment?

The Intercultural Development Inventory® (IDI®) is a statistically reliable, cross-culturally valid measure of intercultural competence owned and copyrighted by Mitchell R. Hammer, Ph.D. The IDI Assessment is rigorously back translated into each available language, and is widely used in corporate, government, military, not-for-profit organizations, and educational institutions (e.g., K-12; universities) throughout the world.

The IDI Assessment is administered by trained and licensed IDI Qualified Administrators. The respondent completing the IDI Assessment is asked to answer a 50-item questionnaire, available online, that can be completed in 15–20 minutes. The Qualified Administrator can then generate Individual and Group IDI Reports based on the respondent’s answers to provide coaching and other services.

2. How do the recent events in the U.S.A. related to the COVID-19 pandemic and racial injustice affect the use of the IDI® Assessment?

The IDI® Assessment measures an individual’s or group’s mindset for dealing with cultural differences. Validation studies of the IDI® indicate this mindset towards cultural differences is stable across a wide range of human experiences and challenges. In only rare cases does a transitional event or traumatic event directly impact how we make sense of or construe cultural differences, the focus of the IDI®.

Whether current events would be considered transitional or traumatic events for a person is going to vary by individual, based on several factors such as the direct impact of the events on one’s work and home life; and whether they or someone they know have directly experienced negative impacts due to these events. In addition, the extent to which these events may be considered transitional or traumatic will vary based on these factors. What we do know is that in only rare cases does a transitional or traumatic event play a role in how an individual makes sense of cultural differences.

Regarding the COVID-19 pandemic: While the pandemic may impact thinking and behavior in regards to safety, in the vast number of cases, this impact does not significantly change our mindset towards cultural differences. However, if a respondent feels their thinking and behavior has changed specifically towards how they engage cultural differences, you may wish to ask them to reflect on how this transitional situation may impact how they make sense of cultural differences and commonalities as identified by their IDI® results.

Regarding events around racial injustice: Due to the cultural nature of these events for many, it is possible that these events may be considered transitional or traumatic, and may be reflected in IDI® results. That being said, an individual’s results will still be valid of their current experience, and will present an accurate portrait of how the person is making sense of cultural differences.

In any case, the IDI® profile results present an accurate portrait of how an individual makes sense of cultural differences.

While we may see an effect on IDI® results as a result of current events, IDI®, LLC does not recommend waiting to administer the IDI®, and in fact, believes this is a more important time than ever to engage individuals in this work and conversations. We encourage you to continue using the IDI® as you have prior to current events, but also encourage you to make time and space for conversation, if needed, around how these events could potentially be impacting respondents, and how this may be affecting profile results.

3. I am in charge of locating an instrument to use in our company-wide diversity and inclusion efforts. What can I present or provide as a handout to our team regarding the IDI® Assessment?

In summary, 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 and in a paper-and-pencil format that can be completed in 15–20 minutes.
